The invention relates to a tool for disassembly of the cutter, in particular from the holder containing the basic element that hosts the Executive body, the Executive authority has eject the mandrel and arranged to move.

Such instruments are used for example in road milling, recycler, career harvesters (surface miner), etc. They are used for dismantling of the cutters, in particular cutters with shank (picks). While the cutters are clamped in the respective slots of the holders. Socket holders are made usually in the form of through holes. Themselves the holders mounted on the pipe surface milling drum, in particular welded or fastened removable on the basis of load-bearing elements, which, in turn, is welded on the pipe surface of the milling drum. To facilitate dismantling of the pick-known tools, such as described in patent publication DE 296 23 508 U1.

This tool includes two lever arm, connected by a hinge. However, one of the lever forms a shoulder eject the mandrel, and the other lever forms a handle. Eject the mandrel to its free end may be inserted into the slot of the tool holder so that the end rests on the shank deleted cutter.

His second lever tool is NT can be installed on the supporting flange pipe milling drum. In this case, the cutter by moving the lever can be pushed out of the socket holder. After that from the socket of the tool holder is removed eject the mandrel. Manipulation of the double arm in a tight mounting space seems to be laborious and time consuming. Therefore, the abutment flange on the milling drum, which is not always present.

The prior art desoldering tools that tightening the foot can be mounted on the working head cutter. This requires circumferential groove in the working cylinder and in engagement with which is constricting the foot. These tools do not, however, provide for disassembly of the cutter when cutting heads are worn so that the groove has not been preserved. Also can not be dismantled cutters with broken work heads. Such tools are known from the patent publication DE 43 23 699 C2, DE 32 23 761 A1, DE 84 03 441 U1 and US 6,526,W.

Another tool is described in the publication DE 30 26 930 A1. This tool has a support arm that can be mounted on the holder. The abutment shoulder connected with the pivoting arm that has a handle. The tool holder includes a rectilinearly moving the plunger. For disassembly of the cutter roller lever mounted on the plunger facing away from the handle lever shoulder. AFL is stvie movement of the handle the plunger can move and push the cutter from the socket of the tool holder. Mounted on the tool holder plunger causes additional expense constructive and mounting material. In addition, this requires an increase to the tool holder mounting space, which is unacceptable in modern precision cutters.

Further, this design requires the installation of the cutter in the slot of the tool holder type blind hole. When work can occur contamination that leads to the exit of the system.

The objective of the invention is to create an instrument of the above type that provides a simple and rapid replacement of the cutter.

This problem is solved due to the fact that the Executive authority directly or indirectly connected to a cylinder-piston system fill fluid medium, or with a motorized node. The cylinder may constitute, for example, liquid cylinder, in particular a hydraulic cylinder, which is loaded by circulating oil. In particular, it creates a high pressure on the piston and correspondingly high force impact is transferred to the Executive body. Thus, the cutters can be reliably removed without greater effort. Electrically driven, the installation may represent, for example, the mechanism of type “screw-nut”, which is driven by an electric motor.

In a preferred embodiment, about what westline of the invention can be provided, that the Executive body is mounted on the base element can be rotated about a fixed pivot bearing. The base element can be designed for tool holder and repeatable process for Stripping (removing) is carried out by means of a fixed pivot bearing.

If stipulates that eject the mandrel by moving Executive body moves along an arc trajectory, may change the characteristics of the moment. For example, if a specific calculation parameters at the beginning of the movement can generate high torque, which then gradually decreases. Consequently, this allows a simple way to satisfy the requirement that at the beginning of the movement, it is first necessary to overcome the friction clutch between the cutter and the socket of the tool holder.

The preferred way is envisaged that the base element has a support section for supporting directly or indirectly on the holder, for example on snoozester disk. Due to the rigid binding of the tool to the tool holder can refuse additional supporting elements, such as squeezing the bead on the pipe milling drum. This allows the pipe milling drum compact arrangement of the individual holders and excluded additional costs to the it is, when talking about the state of the art.

The preferred way to support the use of such places on the holder, which are not subject to excessive wear, so that the tool can be used to continuously reproducible basis. In particular, iznomasana washer, which is usually between the working cylinder and cutter and the installation surface of the tool holder, offers such a perfect resting place.

The reference area may be located, for example, by using Timna element. In the presence of forked squeezing element can be placed on the holder so that the supporting section is laterally relative to the working head cutter. In this case, the reference area also captures snoozing washer.

In a preferred embodiment of the invention can be provided that the base element at a distance from the reference site is located outside bearing surface for bearing on the holder. The reference area and the reference surface can create a certain connection of the tool to the tool holder. Thus the tool is constantly in equally attached to the tool holder.

A possible variant of the invention may differ in that the base element has a slot that hosts the Executive body between the two bounding the slot side walls, moreover, the side walls have a reference nests that are running can be rotated by the Executive body.

This simple way of doing provides a stable move of the Executive body between the two side walls.

Another preferred variant of the invention provides that the move of the Executive authority is limited to at least one located on the base element focus. The Executive body may be limited in this case in its motion. When this movement is controlled in such a way that eliminates the jamming of the Executive body in its end positions.

In the initial position of the Executive body at the proper limit stop is positioned so that it is easy overlay on the tool holder. The limitation of the stroke of the Executive body in position dismantling prevents jamming of the Executive body in the socket of the tool holder.

It is possible, in particular, provide that the Executive body is moved from the starting position to the position of the removal and that the Executive authority by the spring element can be fixed in the original position and preloaded by springs. This measure ensures that when the cylinder without pressure the Executive body of f is ciruits in its initial position or is returned in this situation. Of course, due to the use of, for example, double action cylinder can opt out of pre-stressing of the spring.

To provide a simple and reliable service tool even in hard to reach places can be provided that the base element is indirectly or directly by means of the connecting element is connected with the handle, and the handle due to the rotary support is rotated relative to the base element.

In a preferred embodiment, the invention can provide that push the mandrel is connected with a lever arm that has a coupling element for rotatable mounting of the piston rod, and a lever installed at a distance from the above-mentioned coupling element can be rotated.

Below the invention is explained in greater detail on the basis shown in the drawings of embodiments. Shown:

Figure 1 shows a tool 10 with a handle 12. The handle 12 is mounted battery. By means of two electrical contacts 11, the battery may be recharged from the charging station. The battery is used to power the electric motor. This motor is attached in the housing, which is attached to the handle 12. This extra housing is placed in the cylinder 13. In this case, the cylinder 13 is designed as a hydraulic cylinder, so that in side the casing is mounted a corresponding circulating hydraulic system. In the cylinder 13 between the two end positions moves the piston. On the handle 12 is built split 12.1 mechanism. This split 12.1 mechanism closes the contact when the second circuit and thus starts the motor in attached housing. The motor in connection with the hydraulic system actuates the piston in the cylinder 13. As an alternative valid also in the handle 12 to build the line leading to the connections for the supply of the fluid medium on the handle 12. Join for supplying a fluid medium is designed as a fast connection.

They can be connected to the return connection elements hoses or hoses. This sleeve or hose may be flexible, for example, from hydraulic road cutters or career harvester. Built into the handle 12 of the line leading to the cylinder 13. In the cylinder 13 posted by rectilinearly moving the piston. The movement of the piston may be regulated by means of valve, which is controlled through split 12.1 mechanism on the handle 12. To the cylinder 13 can be connected is shown in figure 4, the adapter 20. This adapter 20 will be explained below in more detail with reference to figures 1 and 4. It contains basic element 20.1. Basic element 20.1 limits two side walls 20.4 nest 20.2. In this nest 20.2 installed with the possibility of moving the Executive body 60 in the form of a lever. The Executive body 60 has a lever shoulder 64, with which it is connected are made as one whole eject the mandrel 65. Eject the mandrel 65 is made curved. The free end of the ejector mandrel 65 is made of round-arched. Lever PL is Cho 64 at its converts from push mandrel 65 end provided with a hole, which forms a bearing socket 63.

This anchor socket 63 in alignment with the corresponding holes in the side walls 20.4. Through the aligned holes and a support slot 63 can be opened and securely retaining rings pivot pin 20.6, as shown in figure 4. Pivot pin 20.6 forms the axis of rotation, which according to figure 1 is vertical to the image plane. In the zone between the base of the socket 63 and the junction of the ejector mandrel lever 65 with the shoulder 64 of the lever shoulder 64 provided with the element 62 connected. This element 62 may to join their support slot 15, the piston rod 14. The piston rod 14 at its facing away from the anchor slot 15 end has a flange 16, as shown in figure 4. On a basic element 20.1 molded are made as one whole with him connecting element 20.10. Figure 1 shows that the connecting element 20.10 has a Cup-shaped socket, through which a through hole is in spatial connection with the mounting socket 20.2. In the Cup-shaped nest is placed the spring element 20.11. The spring element 20.11 made in the form of coil springs. The piston rod 14 is drawn through the spiral spring, so that the free end of the piston rod 14 is in contact with the Executive body 60.

When the piston rod 14 and its supporting socket 15 falls on element 62 connected. R is canoe shoulder 64 in the area of the element 62 has two coaxially between the openings, which can be aligned with a support slot 15 in the piston rod 14.

To this end, the piston rod 14 with its flange 16 is located opposite the speaker of the Cup-shaped socket end of the spring. Then the pressure on the flange 16 of the spring element 20.11 may be compressed up until the anchor slot 15 is not aligned coaxially with the holes in the coupling element 62. Through the aligned holes and anchor the socket 15 may be omitted hinge rod. As shown in figure 4, the side walls 20.4 there are round holes 20.5.

Lever shoulder 64 of its holes can be aligned coaxially with the holes in the coupling element 62. Then the hinge pin passes through holes 20.5 into the holes of the lever shoulder 64 and through the anchor slot 15. Therefore, it may be easy connection and accordingly, the separation of the piston rod 14. In close position, as shown in figure 4, the piston rod 14 is fixed preload of the spring. Thus, also the Executive body 60 is fixed in this position.

By means of the connecting element 20.10 adapter 20 can be connected to the side housing. Between the connecting element 20.10 and attached housing formed bearing rotation, so that a side of the housing can be rotated relative to the base element 20.1. In mounted in the second position, the piston rod 14 with its flange 16 adjacent to the introduced into the cylinder 13 piston. When the piston in the cylinder 13 is in its end position, which defines the extended position.

As shown by figure 1, in the area of the mounting socket 20.2 basic element 20.1 provided by the stops 20.8 and 20.9.

These lugs 20.8 and 20.9 serve to limit the travel of the Executive body 60. This Executive body 60 has corresponding opposite surfaces which can come into contact with stops 20.8 and 20.9. In figure 1 the Executive body 60 adjacent to the emphasis 20.8, and figure 3 the Executive body 60 adjacent to the emphasis 20.9.

As can be seen in figure 4, the base element 20.1 molded as one piece with it the release element 20.13. The release element 20.13 made forked and has a support section 20.14.

The above-described tool 10 is used for Dismounting the cutter 50, which are mounted in the tool holder 40. The tool holder 40 is fixed with the possibility of replacement in the base support element 30.

For this purpose, the base supporting member 30 has a socket in which is mounted a cap element of the tool holder 40. Its clamping screw 32 tool holder 40 can be fixed on the base support element 30. The base supporting member 30 has a concave bearing surface 31. It can be installed on the pipe surface milling drum and welded thereto. The holder 40 includes a nozzle 41 in which a hole is provided by the slot 43 of the tool holder. The slot 43 of the tool holder is accessible from the back side through the aperture 42. The cutter 50 is made in this case as the pick. It contains a working head, which are molded as one piece shank 51 of the cutter. On the shank 51 is set clamping sleeve. The clamping sleeve is installed without the possibility of moving in the axial direction on the shank 51 of the cutter, but with the possibility of free rotation in the circumferential direction. As shown in figure 1, its shank 51 of the cutter 50 is installed in the slot 43 of the holder 40 so that it is fixed in it the clamping sleeve. In the inserted position, the cutter 50 of his working head supported on snoozing washer 54, which is attached to the shank 51 of the cutter. Iznomasana washer 54 is located between the working cylinder and cutter and clamping sleeve. Iznomasana washer 54 its facing away from the working head side adjacent to the supporting surface of the holder 40.

In operating mode, the cutter 50 of his working head can rotate iznomasanai the washer 54. Also the shank 51 of the cutter is rotated in the clamping sleeve. Working the pick head 50 typically has a top 52 of the cutter, made for example from solid alloy.

When the cutter 50 reaches the state of wear, it must be removed. This use is described in the drawing, the tool 10. With this tool, the t 10 is placed on the tool holder 40, and the release element 20.13 their support section 20.14 adjacent to the front side iznomasanai washer 54. Of course, the release element 20.13 may be supported directly or indirectly on any suitable position of the tool holder 40.

In the mounting direction of the cutter between the pressing element 20.13 and the tool holder 40 should be formed geometric circuit. Further, the base element 20.1 has a thrust surface 20.7, which is the basic element 20.1 rests on the surface of the tool holder 40. Due to the hard surface 20.7 and reference section 20.14 can be created a certain accession of the tool 10 to the tool holder 40. When applying the tool 10 to the tool holder 40 through the aperture 42 penetrates also eject the mandrel 65. Thus the free end of the ejector mandrel 65 is located opposite the free end of the shank 51 of the cutter. The free end of the shank 51 of the cutter forms a bearing surface 53. When the tool 10 is shown in the figure 1 position, actuates split 12.1 mechanism on the handle 12.

When triggered the split 12.1 mechanism starts the motor in attached housing. It pumps the hydraulic fluid in the cylinder 13, resulting in moving the piston in the cylinder 13. As the piston directly or indirectly adjacent to the flange 16 p is ravago rod 14, he also moves shown in the figure 2 position. When this movement is also the compression of the spring element 20.11.

The resulting displacement of the piston rod 14 Executive body 60 is rotated about its pivot socket 63. This Executive body 60 to its eject the mandrel 65 is so penetrates into the slot 43 of the tool holder, the free end of the ejector mandrel 65 comes into contact with the supporting surface 53 on the shank 51 of the cutter. When moving the Executive body 60 of the cutter 60 is ejected from the slot 43 of the tool holder. When the clamping sleeve is slid into the cylindrical hole iznomasanai washer 54. When the clamping sleeve is radially compressed inward, resulting in partially compensated by its clamping action. Due to this, less the buoyancy force. The installation movement of the Executive body 60 limits the focus 20.9.

In this end position also triggered to shut off the flow switch current to the electric motor in attached housing. This is the working position shown in figure 3. When the cutter 50 is completely out of the socket 43 of the tool holder. Due to the disconnection of the electric motor is reduced hydraulic pressure of the piston.

Now the spring element 20.11 can reduce your preload and Executive body 60 counterclockwise returns shown in figure 1 to its original position. When the cylinder piston 13 is returned to its original position. Now the tool 10 can be removed from the tool holder 40, resulting freed snoozeworthy disk 54. The cutter 50 can be removed.

Figure 5-8 shows the versions of the tool. The images according to figure 5-7 system providing a replacement cutter, which consists of a base support member 30, the tool holder 40 and the cutter 50, corresponds to the device according to figure 1-4. On Fig shown that tools 10 according to the invention is not limited to the implementation of these are in principle known systems replacement. Moreover, acceptable use, when the tool holder 40 are welded directly to the pipe milling drum F (see welding seam 44).

The design of the tool according to figure 5 corresponds essentially to a variant of execution of the instrument figure 1-4. Structurally differ only by the Executive body 60. This Executive body 60 is made as a planar mechanism in the form of saving mounting space articulated chetyrehzvennoy. It uses two levers 61, 65.2, through which the hinge supports 65.1, 65.4 linked to eject the mandrel 65. In this case the axis of swing (rotation) is oriented perpendicular to the image plane.

On the reverse side relative to the ejector mandrel 65 is icag 61 via a pivoting bearing (hinge finger 20.6) is connected with the piston rod 14. This coupling zone corresponds to the coupling zone of the piston rod 14 with the Executive body 60 according to Fig.1-4. The link is on the above options.

The second lever 65.2 his converts from push mandrel 65 end by means of pivot bearing 65.3 connected with the side walls 20.4. The swing axis is also oriented perpendicular to the image plane. Figure 5 shows the initial position of the tool. When triggered the split 12.1 mechanism, the piston rod 14 in the image plane is shifted straight down. While United via an ejector mandrel 65 of the levers 61 and 65.2 synchronously rotated in a clockwise direction. Simultaneously eject the mandrel 65 enters into the slot 43 of the tool holder and pushes the cutter 50 on its supporting surface 53 of the slot 43 of the tool holder, cover clamping force of the clamping sleeve S.

After reaching the extended position of the spring element 20.11 again pressed the Executive body 60 shown in figure 5 original position.

Figure 6 shows another variant of the design tool and the adapter 20 here also corresponds essentially to the adapter 20 to the tools 10 figure 1-5. So we are talking here only about the distinctive characteristics and, in General, reference is made to the above options. Attach the capacity element 20.10 adapter 20 is equipped with a Jack, in which is inserted and fixed therein the curved pipe 66.2. In this tube 66.2 wound flexible (non-rigid) element 66.7, in this case, link chain, such as is used in principle also in drive technology. One end of the link chain pivotally connected with a support slot 15 of the piston rod 14. On the other end of the chain, the last link in the chain forms eject the mandrel 65. Figure 6 again shows the initial position of the tool. When triggered the split 12.1 mechanism, the piston rod 14 is shifted down. When he walks into a cylindrical docking area of the pipe 66.2.

Link chain is moved in the pipe 66.2, and pipe 66.2 prevents buckling link chain. Eject the mandrel 65 abuts against the abutment surface 53 of the cutter 50 and pushes it out of the slot 43 of the tool holder.

When link chain reaches the zone of the slot 43 of the tool holder, it prevents it from buckling. After reaching the end position the spring element 20.11 again returns to the Executive body 60 shown in figure 6 to its original position.

In the tool with 7 instead of the link chain in the pipe 66.2 served fluid 66.3, preferably liquid. To porshneva the rod 14 by means of the articulated slider attached to the piston 66.1. The piston 66.1 its outer contour is sealed by means of sealing rings which and the inner wall of the cylindrical zone of the pipe 66.2. The second end of the tube, also made cylindrical, wound up with the seal of the second piston 66.6. The piston 66.6 can move rectilinearly and is pushing the mandrel 65. Pipe 66.2 through the aperture 42 may extend into the slot 43 of the tool holder, so that pushes the mandrel 65 is located opposite the supporting surface 53 of the cutter 65. When moving the piston rod 14 of the piston 66.1 slid into the pipe 66.2. Fluid passes is the installation movement of the second piston 66.6. Thus eject the mandrel 65 pushes the cutter 50 from the slot 43 of the tool holder. With the loss of load of the piston rod 14 of the spring element 20.11 presses Executive body 60 to its original position. When this plunger 66.1 moves up. By creating a vacuum fluid working environment 66.3 moves the second piston 66.6 to its original position.

On Fig shows the tool 10, the handle 12 which has a built motor 66.8. Output shaft 66.9 motor 66.8 provided with a spindle 66.11. On the opposite side of the motor 66.8 through bearing 66.10 is mounted for rotation adapter 20. Further, the adapter 20 between the two side walls 20.4 placed Executive body 60, which in this case has the form of a disk. The Executive body 60 along the edge fitted with a toothed crown 66.12, which is engaged with the screw 66.11.

Use the Executive body 60 is fixed in the adapter 20, moreover, the reference slot 63 forms the axis of swing. The Executive body 60 carries eject the mandrel 65, which is formed as one unit and eccentric relative to the pivot slot 63.

The tool 10 also eject the mandrel 65 can be opened through the aperture 42 in the slot 43 of the tool holder, so that pushes the mandrel 65 is opposite the support surface 53 of the cutter 50. When triggered the split 12.1 mechanism on the handle 12 starts the motor 66.8. Thus is rotationally driven output shaft 66.9. The spindle 66.11 by means of the ring gear 66.12 rotates clockwise Executive body 60. Due to the distance between the ring gear 66.12 and swivel bearing 53 is created rather large lever arm. Using a screw mechanism can significantly reduce the effort. Eject the mandrel 65 by rotation of the Executive body 60 pushes the cutter 50 from the slot 43 of the tool holder. After reaching the advanced end position, the motor 66.8 reverses and rotates in the opposite direction until such time as the Executive body 60 will not take shown Fig its original position. In this position, the motor 66.8 off.

Of course, the described tool 10 can also be used with the appropriate variety of holders 0 and systems providing a replacement cutter.
