The technical field

The present invention relates to upper clinovia mechanism containing the device mounting tool, at least one tool equip lateral surface, and wedge mechanism includes a slide caliper and the leading element, and the device mounting tool for such a wedge mechanism.

The level of technology

Wedge mechanism is used for vertical deflection current efforts of the press, which is used for the manufacture of molded sheet items, in particular automotive body parts, in any direction from the vertical. It is in the manufacture of body parts due to their geometry, which includes the undercut and other irregular areas, creates a problem in that these details cannot be processed using a press or pressing in a vertical direction of the dies or presses, so this should be used wedge mechanisms. Such wedge mechanisms consist essentially of a guide element for a slide caliper or guide plate, guide element or lead wedges and slide caliper, which through two other elements transmit the pressing force to change direction due to the wedge-shaped. Depending on the use of the wedge mechanism mo is et to be located at the top or at the bottom of the stamp. In both cases it produces the same effect, namely, the deviation created by the stamp of efforts in the direction deviating from the vertical. Typically, the angle of deviation of the tonnage is determined by the fact whether the wedge mechanism at the bottom or top of the stamp. Deviation up to an angle of 20 to the base of the stamp (horizontal) is provided mainly through V mechanisms in the lower part, and a deviation of greater magnitude in order to ensure the best possible removal of body parts of the stamp is provided mainly through V mechanisms in the upper part of the stamp. The deflection angle mainly depends on what processing should be performed by a stamp, and wedge mechanisms are used in particular when punching holes, cutting areas up to the edging and processing copier areas of undercut, to which there is no access from above or below.

Thus, the wedge mechanism is the Executive body of the stamp and is used to drive, for example, punch, cutting knife or polimetrica in the stamp. Himself wedge mechanism is usually not in contact with the product. Contact or incision in the body part is only fixed on Klinova mechanism tools (punch, cutting knife, polimetrica stamp and so on). Tool the options are set appropriately on the slope of the wedge mechanism to allow obliquely directed processing of the product. Due to the oblique or inclined directional designs are not only the difficulties of production, but also increased the cost of manufacturing. This can be understood already from the fact that the first Assembly, as well as changing standards of the punch and die, you need to unmount the whole wedge mechanism. However, in many cases it is very difficult to do, because the guides leading wedge due to non-rectangular outer surface very poorly clamped by the vise. Therefore, the installation tool may often be accompanied by large and unreasonable costs.

To solve this problem have been developed device mounting tool, which can be secured to the slide caliper (slider) wedge mechanism for cutting and forming tools could be pre-installed on these devices outside of the wedge mechanism and stamp with his machining tools and thus would provide a quick and easy tool change.

Such a device mounting tool is disclosed, for example, in patent document FRG No. 19860178 C1. This device fixing tool called a mounting plate, is removed using the available rear mounting screws. This means that this device can be disassembled only when the slide caliper offset the top so that become available from below, i.e. from the side of the host item. The device mounting tool is made in the form of a rectangular plate and is located on the front side of the slide caliper, and from there it is located down in the direction of a guide for the slide caliper is based on the leading element. In addition, the device mounting tool provided with T-slot for transmission to the slide caliper side efforts shift.

Such devices fixing tool have a great advantage in that it's much easier to replace worn-out tools, as well as the editing during production, as it requires to remove from the stamp only a small part wedge mechanism, namely the attachment of the tool to be replaced by the tool. This overrides the complete dismantling of the entire wedge mechanism, requiring large expenditures of time and in most cases expensive. Usually this dismantling process is very time consuming due to the very constrained space inside the stamp and difficult access clinovia mechanism. This requires that the device mounting tool met the high demands on tolerances and effort, created inside the stamp, and this, among other things, means that the device mounting tool is not up to what should be disconnected by itself and must also be perceived lateral shearing forces. In addition, it should be easily accessible, and its Assembly and disassembly should be done with repeatable accuracy to meet the high requirements for accurate positioning of the instruments on Klinova mechanism. Because the wedge mechanisms for the most part passed the efforts of several hundred tons, it is required that the device mounting tool when moving, that is in the workflow, was planted on Klinova mechanism securely and rigidly, without deflection. When reverse motion device fixing tool also should not bend or break with wedge mechanism or dislodged from their position, even if a fixed tool during the punching or molding engages inside the product and creates resistance that must be overcome when pulling back of the instrument. Generally, the efforts of the reverse range from 10 to 15% of their work effort, there are important efforts that should be interpreted by the device fixing tool.

According to patent document FRG No. 19860178 C1 mounting plate can be removed using the available rear mounting screws, and the mounting screws are located in the horizontal direction, i.e. in the direction of the stroke wedge mechanism. If the mounting plate is perpendicu the Jarno or at least, inclined to the direction of the stroke wedge mechanism, the fastening screws should have a fairly large dimensions, that is impossible, mainly because of the very constrained space inside the stamp.

The device mounting tool should prevent the formation of burrs and unnecessary wear of the machining tools, and tolerance or repeatable positioning device fixing tool must lie within 0.02 mm, Usually known device, including the device according to patent document FRG No. 19860178 C1 cannot ensure compliance with such strict tolerances.

Disclosure of inventions

The problem to which the present invention is directed, is to create a top wedge mechanism with a device for fastening instrument and device fixing tool for such a wedge mechanism, which meet the above requirements for repeatable accuracy and tolerances to reduce the user cost of manufacture and maintenance. The device mounting tool should be easy to disassemble with a wedge mechanism, however, when mounting repeatable way accurately positioned and fixed on Klinova mechanism to be sustainable itself with the boe and during operation to maintain accurate positional position under the action of high effort pressing.

In accordance with the invention the solution of this problem in relation to the upper wedge mechanism under paragraph 1 of the claims is due to the fact that the device mounting tool fortified with the possibility of dismantling in a downward direction relative to the upper wedge mechanism in its operating position.

In relation to the device mounting tool for such a wedge mechanism solution of the problem is due to the fact that the device mounting tool includes at least one connecting device for connection by means of kinematic and/or force-closure with a slide caliper (slider) and the leading element.

Further decisions on the development of the objects of the invention are defined in dependent claims.

This solution created upper wedge mechanism, in which due to the possibility of dismantling the unit fixing tool down relative to the wedge mechanism in its operating position is achieved the great advantage that ensures good accessibility without interference from structural components, such as matrix stamp or cutting matrix. In known devices, for example, patent document FRG No. 198 60 178 C1, there is provided a solution to the problem of difficult access to the fastening means./p>

In accordance with the invention, the device mounting tool for wedge mechanism, which is connected by kinematic and/or force-closure with slide calipers, and the leading element, allows, essentially, to prevent the violation of positioning during operation of the drive mechanism. Further, it gives the ability to withstand repeated the accuracy of mounting the unit mounting tool and also when changing or replacing a fixed tool at the desired minimum range of less than 0,02 mm due to the fact that the device mounting tool are connected by kinematic and/or force-closure with slide calipers, and the leading element, the support and positioning are carried out at least in two directions to achieve the desired positioning accuracy.

By providing opportunities to dismantle the device mounting tool at an angle essentially perpendicular to the direction of the stroke drive mechanism in the direction of the open wedge mechanism achieves better access to the mounting means or the means by which the device fixing tool is fixed on Klinova mechanism. In the solution according to the patent document, the Federal Republic of Germany No. 19860178 C1 slide caliper and the leading element should be NR is the beginning moved away from each other at a distance, to be able to detach the mounting plate and remove it with a slide caliper. Due to a favourable opportunity to dismantle the device mounting tool with a wedge mechanism without such separation at the leading element and the slide caliper is provided not only more easy to change, but also cost savings, since the replacement device fixing tool can be made faster than in the known solutions of the prior art.

Currently, the increasingly widespread practice of serial manufacturing standard wedge mechanisms. For the buyer this means that he can get from the warehouse of the seller wedge mechanism standard production, in which the buyer only need to individually perform the fixing grooves for concrete cutting and forming tools, i.e. machine tools. It also means that the finished wedge mechanism Assembly needs to be disassembled and handled in its own manufacturing equipment in a special way for a specific use, i.e. in particular to perform the corresponding fixing grooves for machine tools. Basically here you can revert to the mounting plate in patent document FRG No. 19860178 C1, where costs can be reduced, as this circuit platanifolia, essentially, in the form of a flat plate with parallel planes, which can be easily clamped in the processing device. However, this mounting plate can not be easily installed on any standard Klinova mechanism and removed from it. In contrast, the device mounting tool according to the invention can be easily installed on Klinova the engine and disassembled, so that the cost of these operations can be reduced by 80%.

Because the device mounting tool according to the invention preferably contains at least one surface essentially parallel with the tool-side surface, it is very well suitable for additional processing, as it can be clamped in a vise and similar devices processing equipment much easier than a non-rectangular housing of the slide caliper or master element, which for the most part, have an irregular shape. This advantage of the easy clip also has a mounting plate according to patent document FRG No. 19860178 C1. Compared with the device mounting tool according to the invention has a significant advantage in that the connecting device for the connection by means of kinematic and/or force-closure with slide caliper (RAM)and are well-versed element provide reliable connections with both elements and due to this positioning and retention from tipping over and displacements in different directions.

Equipment wedge mechanism with a device for fastening tool according to the invention creates a significant economic advantages in terms of manufacturing and maintenance wedge mechanism, and General operating expenses and the cost of primary processing based on the production time of one wedge mechanism can be reduced by more than 50%. In other cases, operating costs and the costs of initial processing up to several times the cost of the purchase of wedge mechanism.

Preferably the connecting device for connection by kinematic circuit is connected to the tongue and groove. Due to the presence of such compounds in the tongue and groove or several connections between the device mounting tool and other components is provided trouble-free to obtain a certain positioning and also under high effort pressing. Thus in the course of feeding can be prevented deflection device mounting tool, because the connection to the tongue and groove may be exposed to increased efforts of the pressure in an optimal way, so that due to the connection by the kinematic circuit device mounting tool is not rejected, and works together with wedge mechanism as the whole. Also during the reverse course of the machining tool from the products when he can easily get caught in a product and create a resistance to the output connection by kinematic circuit, such as the connection into the tongue and groove also provides special advantages, as this device fixing tool remains stably positioned on Klinova mechanism.

Preferably the connecting device for connection by the power circuit contains at least one provided on one side of the device mounting tool guiding prism and/or at least one prismatic recess, and/or at least one prismatic section, made in one piece with the base (i.e. the main body of the device fixing tool. Alternatively, at least one guide prism is made as a separate element that can be connected or is connected to the base of the device fixing tool. In a particularly preferred exemplary embodiment, at least one guide prism and the base of the device mounting tool can be made with the possibility of connection or are connected by means of the fastening means, in particular screws. Due to the presence of the guide prism as the connecting device is for connection in particular, with the leading element wedge mechanism creates a profitable opportunity to create a support device mounting tool on the leading element in the process of moving when processing items in process of submission and reverse course.

Connection guide prism with a device mounting tool, i.e. their execution for one or only connection between them can be determined depending on the specific values of the wedge mechanism and its design. Guide prism may be made in the form of a block element with slip planes, the response to the leading element. In an alternative embodiment, may be provided only prismatic notch. The specific implementation may be determined depending on the effort that must be considered. The device mounting tool and guide prism for one unit is particularly suitable for small V-mechanisms and implementation guide prism in a separate item is better suited for medium to large wedge mechanisms. While this may also guide prism can only be executed in the form of a thin sheet element or in the form of a compact design details that also depends on the size of the wedge mechanism and the efforts that are generated when handling products.

For that is about, in order not to create obstacles when sliding on the master element, the guide prism may be preferably provided with fastening means, which are arranged in the longitudinal direction of the device mounting tool and at least partially recessed into the body of the guide prism. For disassembly of the guide prism device-mounting tool is sufficient to move the slide caliper in the process direction. With appropriate fastening means in the working position of the upper wedge mechanism become available at the bottom, that allows you to easily carry out the dismantling device fixing tool. The device mounting tool may be advantageous way dismantled at an angle perpendicular to the direction of the stroke drive mechanism in the direction of the open wedge mechanism with the movement when mounting or Dismounting down relative to the upper wedge mechanism in its operating position. Essentially a right angle relative to the direction of the stroke wedge mechanism provides easy access for Assembly and disassembly of the device fixing tool.

Preferably the wedge mechanism according to the invention is equipped with at least one directed to a device for fastening tool portion which to play is embracing efforts backstop provided, at least one connecting device for connection with a device mounting tool by kinematic and/or power circuit. Preferably such a connecting device for connection by kinematic circuit is connected in tongue and groove, which in a particularly preferred exemplary embodiment is provided on the side of the device mounting tool opposite to the location of the guide prism. Due to this, after mounting the device mounting tool part forming the connection by kinematic circuit, pressed into the desired position and rigidly retained therein without the use of additional fasteners, for example, by screws or other fastening elements. However, the mounting of the tool on the side to which it may be removed from the wedge mechanism may be attached to clinovia mechanism using at least one fastening means, in particular by means of a screw. However, this is not a necessary condition, since the positioning device fixing tool it's planted by the kinematic and power circuit between the slide caliper and the leading element.

For the perception of increased effort mass acceleration is preferably OEM home button Flex cable is the TREN, at least one lateral locking plate that overlaps the region, at least one of the guide prism and passes to the host item. In a particularly preferred exemplary embodiment, this at least one lateral locking plate engages the leading element on the side, top or bottom. Also preferably, when at least one lateral locking plate passes between the slide caliper and the leading element and in particular mounted on the slide caliper. This locking plate fixation device fixing tool in the lateral direction, i.e. in the direction in which the connection by the kinematic circuit in the form of connection in the tongue and groove oriented in one direction only, does not create a holding effect. The presence of the guide prism creates the most desirable fixation in the lateral direction. However, it was with great effort acceleration of the masses in addition to steady the guide prism preferably also to lock it in the lateral direction relative to the leading element by means of the fixing plates. Due to the fact that at least one locking plate locks the slide caliper and the leading element in relation to each other only in the lateral direction, provides perhaps the th move in the longitudinal direction of the lead element, that is, the locking plate does not impede this movement. For this purpose, at least one lateral locking plate has a corresponding shape, which allows it to engage with the leading element, but not to attach to it rigidly. Preferably the fastening of the locking plates is made on the slide caliper as they slide on the lead element. In principle it is also possible that the locking plate was mounted on the leading element and passed along the outer surface of the sled carriage slidable along them, particularly provided on the recess or groove, which can be performed also on the outer surface of the device mounting tool.

Preferably provided by one or more retaining hooks for the transmission when reverse motion of the slide caliper, and these retaining hooks can capture the leading element type hooks or fixed in it. Preferably, the fixation is carried out in a corresponding groove or recess in the host element, you can move the slide caliper along the leading element.

The implementation of the invention

Figure 1 shows in perspective, in the first exemplary embodiment, the device 10 of the fastening tool when it is mounted on Klinova mechanism 1. Wedge mechanism includes slide 2 slide (slider), the leading element 3 and the guide element 4 to slide caliper, and the guide element 4 and the carrier 2 calipers are held together by the guide clip 5. The device 10 of the fixing tool is attached to the slide 2 slide on their front side 21 of its rear side 20. The device 10 of the fixing tool is connected to the carrier 2 caliper by kinematic circuit through the connection 11, 22 in the tongue and groove. The device 10 fixing tool provided with a protruding element 11, and the slide 2 slide - groove 22. The groove includes a protruding element of the device 10 mounting with provision kinematic circuit.

In facing the leading element 3 side of the base 12 is disorder 10 fixing tool made the recess 13, into which is inserted a guide prism 14. This guide prism 14 are slidable on top of the prism 31 host item 3.

On the front surface 19 (2) of the device 10 of the fixing tool can be strengthened with the tool in the same place, which is selected in accordance with the purpose of the tool. This mount can easily be carried out before installation of the device 10 fixing tool.

As you can see in figure 2, the base 12 and guide prism 14 are connected by screws 15 which pass through the through holes 16, 17 in the guide prism 14 and the base 12. From figure 2 can also be understood that the guide prism 14 is also provided a screw 15 for mounting directly on the carrier 2 of the caliper, and the corresponding holes 16, 17 in the guide prism 14 and the carrier 2 caliper. Due to the fact that the guide prism 14 passes, essentially over the entire surface of the overlap of the slide caliper and a driving element is provided not only particularly good support of the slide caliper with the base 12 to the leading element, but also especially good and hard landing on this leading element.

For especially large wedge mechanism, in which the workflow can be created of high-mass acceleration, to provide better retention of the slide caliper on leading the m element or as the device is forced fixation with two sides on the carrier 2 of the support provided by the locking plates 50, 51. The locking plates 50, 51 are for guiding prism 14 and rely on the leading element 3, as shown in figures 1 and 3. To install the locking plates on the sled carriage provided with appropriate recesses 24, and the locking pads fortified them with screws, as conventionally shown in figure 1. For this purpose, the locking plates in the mounting area have grooves and recesses for recessed head screws in order to eliminate the risk of separation during installation wedge mechanism.

The locking plates 50, 51 are their protruding ends 52, 53, fulfilled in the form retaining hooks into the corresponding recesses or the appropriate region 32 of a driving element 3. Because of this, when the moving wedge mechanism, and therefore of the slide caliper relative to the leading element is further amplified by a reliable retention of both elements on each other. The locking plates can additionally contain other prominent areas for the transmission of efforts at reverse motion of the slide caliper, they come with the link to the head element and contribute to involuntary commit.

The transfer of lateral forces and shifts at the expense of connection by kinematic circuit between the device 10 of the fastening tool and the carrier 2 is of opportu, and between the guide prism 14 and the base 12 of the device 10 through the guiding prism 14 and leading the prism 31, on which the guide prism 14. The actual base 12 of the device 10 fixing tool also pressed the guide prism 14 in the desired position, so that in the process, i.e. during operation of the wedge mechanism is reliably provided the connection by kinematic circuit in this field.

As can be seen in figure 2 and 3, the mounting and Dismounting of the device mounting tool can be carried out without problems in a downward direction to the drive element 3, in this case we are talking about Klinova mechanism 1 on the upper part of the press or on top Klinova mechanism. Due to this eliminates the disadvantage of the known solutions of the prior art in that the dismantling of the device mounting tool must be in the direction of the guiding element for a slide caliper or to another element, around which there is insufficient space. Moreover, when performing device-mounting tool in accordance with the invention and corresponding equipment wedge mechanism possible completely do not pose problems mounting the unit mount the tool on Klinova mechanism and Dismounting.

Precise determination of the position and the accuracy posizionare the project can also be provided with grooves for fingers. Such grooves 18, 23 under the fingers provided on the side of the device mounting tool and slide the caliper (figure 2). In principle, these grooves can also serve for attachment of the slide 2 caliper and device fixing tool to each other.

Due to the fact that there are connections in the tongue and groove, i.e. connections by kinematic circuit may additionally be provided with the desired repeatable position accuracy or positioning device fixing tool on Klinova mechanism, i.e. on the slide caliper and the master element, and the positioning inaccuracy can be reduced to a value less than 0,02 mm in Addition, the best way is possible after dismantling the device mounting tool clamping base in the corresponding processing device and to complete the exact landing grooves to install it punches punch, cutters and other tools, since the front surface and the rear surface of the base device mounting tool is made essentially parallel to each other. This ensures the possibility of a flat clamping and precise landing positioning to perform drillings for fixing machine tools, also with high repeatability. Thus, even after replacing and is the instrument and/or device mounting tool can be satisfied with very high accuracy requirements.

Figs.4, 5 and 6 shows the device 200 in another example implementation. In this version, the base 212 and the guide prism is made different from the exemplary embodiment of figure 1-3. In the embodiment according to figure 4-6 base 212 of the device mounting tool is made essentially L-shaped in side view and includes an ascending section 211 and section 215 extending from it at right angles. Instead of the angular recess 13 in the base is made of prismatic notch 213. Guide prism formed by the mounting plate 214 of the sliding surfaces of the prismatic grooves 213. In the example run in figure 4 and 5, there are two such plates 214 slip. These plates slide rely on leading the prism 31. They can be made relatively thin. Possible additional mounting plates sliding on the base 212 by means of clamps and/or screws that are marked holes 217 in the base 212. It is also possible any other fastening between the plates slip and base. Through hole 217 is also provided the possibility of determining the position and positioning of the plates 214 slide with the desired accuracy. In the prismatic recess 213 has a partition 216, passing in the longitudinal direction of the bottom portion 215 L-shaped base. To the adjacent partition plate 214 of the slide. Thus, the partition so the e is for positioning plates slide with the desired accuracy. Leading the prism 31 is in its middle part to slide along the septum 216. However, in the example run in figure 4-6 is not provided, as in the septum 216 are grooves, which could corrupt leading the lens and prevent it moving.

The lower portion 215 of the L-shaped bases on his side 218 opposite the prismatic recess 213 and converted to slides slide has grooves that cannot be seen in figs.4-6. These grooves are protruding ribs 25 on the underside of the slide caliper (figure 5), with the ribs 25 are arranged in the longitudinal direction of the speaker section 215 L-shaped basic unit fixing tool. Both ribs 25 are interconnected by transverse edge 26 to form a stop for the bottom portion 215 L-shaped basic unit fixing tool. The presence siteplease ribs 25 and grooves best way prevents any movement of the device mounting tool in the transverse direction of the wedge mechanism. Possibly in addition to the connection by the kinematic circuit between the slide caliper and basis in the upper area basis using the speaker transverse ribs 219 (5) in combination with a groove 22 in the upper region of the slide 2 caliper. Thus, in this example, run the mount corresponds to the connection of the drive mechanism of the device is m fixing tool in the exemplary embodiment of figure 1-3. In principle, the lower portion 215 of the L-shaped bases forms a connected portion 12 of figure 1-3. Else additional fastening by means of the fixing plates 50, 51 can be performed in the same manner as shown in Fig.1-3.

In this example, run for 4-6 in the same manner as in example run in figure 1-3, during installation and during processing of the product existing tonnage passed through leading the lens directly on the device mounting tool, and in the process provides stable rigid position relative to the device mounting tool. This favorable impact on precision.

The device mounting tool can be insured against loss with a slide caliper down with screws, screwed from below, i.e. from the side of a driving element, which is adjacent device mounting tool.

7-12 device fixing tool according to the invention the following example is shown when it is set on the slide caliper upper wedge mechanism with the leading element.

The device 300 fixing tool also includes L-shaped base 312. This L-shaped base has an ascending section 311 and the lower transverse him a plot 315. In contrast to the exemplary embodiment in figure 4-6 ver is it rising area 311 on its upper side, addressed to the speaker section of the slide caliper, no protruding edges, but instead made the recess 319. This recess 319 surrounded on three sides by edge bumpers. On an acting section 27 of the slide caliper for entering the recess 319 is provided by a transverse rib 28, protruding in the direction of the device mounting tool. Transverse rib 25 is preferably essentially in such a way that it extends into the recess 319 with the kinematic closure. The rib 28 is particularly well seen on Fig.

The lower portion 315 is made in the form of three longitudinal walls 316, 317, 318. The longitudinal walls are fastened with screws to the underside 29 of the slide caliper. To do this, in the longitudinal walls and the underside of the slide caliper is provided by grooves or through holes for screwing screws in them.

Between the middle longitudinal wall 317 and the outer longitudinal walls 316, 318 are formed longitudinal passages 313, 314 so that they can be inserted prismatic sections 320, 321. After Assembly, the drive mechanism prismatic sections 320, 321 sit on leading the prism 31. They are connected with the base of the device fixing with screws or clamping, or any other connection. Adjusting for different width of the slide caliper and/or the host item, i.e. its leading prisms, may be the ay change the length by the width and along the length of the base and prismatic sections. It can be seen in Fig.7-12, which presents different across the width of the device mounting tool and prismatic parts. This prismatic areas may have lateral surfaces of varying steepness to match the height of the leading prism.

As can be seen from figure 10-12, prismatic sections 320, 321 protruding beyond the outer front edge of the framework 312. However, if it interferes with the installation of the tool on the outer side of the device mounting tool, in principle, we can also perform flush with the outer surfaces of the prismatic sections 320, 321 and 312 fundamentals.

On Fig-17 shows the upper wedge mechanism with the device 400 fixing tool in the following sample run. This upper wedge mechanism differs from the mechanism of figure 1-3 the fact that the leading element 430 is supplied not inclined located the leading prism, and essentially horizontal leading prism 431. Accordingly, the carrier 420 caliper is made on the form so that it is slidable along the leading prism located essentially horizontally. For this purpose, the slide caliper is equipped with a section 428, elongated in the direction to the leading element. Elongated section covers the guiding prism device mounting tool with three sides. Due to this, for directing prism 414 with whom is leased back focus in the direction of the drive. In the rest of the guide prism mounted on the slide caliper in accordance with the exemplary embodiment of figure 1-3. The base 412 of the device mounting tool mounted on the carrier 420 caliper with slots 410, 411, and the carrier 420 of the support provided by the respective protruding ribs 422, 423, and longitudinal grooves 424, 425, including the respective protruding sections 408, 409 basis. Due to this, it also provides the mounting bases of the device mounting tool for slide caliper by kinematic and force-closure. Guide prism 414 may be mounted on a slide caliper and on the basis of screws in accordance with the exemplary embodiment of figure 1-3.

In addition to the described and shown in the drawings of examples V and mechanisms designed for them devices fixing tool, there are many other modifications, which are provided for the connection between the device mounting tool, a slide caliper and the leading element by kinematic and/or power circuit. In particular, it is also possible different combinations of structural characteristics represented in the drawings, the device mounting tool depending on usage.
