The invention is explained in more detail as an example with reference to the accompanying drawings, which represent:

figure 1: schematically a device for the controlled and monitored the implementation of the process for placement of the pipe clamp;

figure 2: schematic crimp tool for placement of the pipe clamp;

figure 3: processing the body or sponge tube ticks;

figa-3G: schematically the process or the basic idea of the invention;

figure 4: opravlyaushi-measuring and control device for a managed and controlled implementation process;

- figure 5: chart of the process of compression or clamping with clamping jaws shown in figure 1-3.

1 schematically shows a device for the controlled and controlled placement of the clamping ring, for example, when placing a plastic or rubber hose connecting the nipple or for making connections pipe-hose, for example, in a hydraulic system or in the car.

In opravlyaushi-measuring and control device 1 can be set and control the various processing parameters that are important when placing the clip or clamp 33, so that the connection hose-nipple or hose-trovaporno be made reliably in accordance with the required quality standards. The device 1 is installed first, different values 3 lengths or distances, for example, so that it was possible to detect a passage of a segment of the path during processing or the length or distance on the clip or clamp. Further, the device 1 is capable of setting 5 tolerances within which it is possible to vary the length of the path or the length or distance. On the display 9 displays effectively the path or measured length or distance, and on the basis of this display additional indicator 7, for example, visually shows which countries not specified or the specified value 3 within tolerances 5 in the process or not. For example, the LEDs 7 can contain red and green light bulbs, and in the positive case, the light turns green, and in the negative - red. Of course, can be provided by acoustic signals, in order to immediately be discovered, does the specified value.

There are different handles 11 settings, which you can install the operating conditions during processing. Thus, the handles 11 settings you can choose the speed of processing, speed drain, etc.

There are key 13 enter to set the value achieved on the clamping ring or clamp clamping force or reverse effort in p is acesse processing. Provided key 15 values tolerance and indicators 11, showing whether the value displayed on the display 19 and measured on the clamping ring or clip with the specified value 13.

Through an electric line 25 and pneumatic control line 27 device 1 controls the clamping tongs 29, which at its front side has two sponge or two legs 31 for the implementation of the process or fixing clamp 33 to secure the hose 37 to the pipe or nipple 39 of the pipe.

Figure 2 clamp clamp 29 is depicted in the enlarged view, and, for example, on the rear side of the clamping jaws 29 may be provided button 26 enable to start the process of clamping or compression. Of course, the launch or implementation of the process of clamping or compression can also occur by a corresponding control device 1 or the start can happen automatically and periodically, particularly when we are talking about automated or robotized operation.

In the front part 30 of clamping jaws 29 are one or more of the pressure piston or pressure cylinders (not shown), as known from the prior art for the operation of clamping jaws. These pistons or cylinders actuate with the possibility of longitudinal movement of the clamping wedge 32, which movement is drop forward breeds two rollers 38, responsible for the convergence or divergence of the two clamping jaw 31 ticks. These gripping jaws 31 are fixed in the manufacturing of the cylinder 40 with two fingers 42.

Figure 3 operate the cylinder 40 is depicted in an enlarged view and in the extended condition, wherein the longitudinal wedge 32 is depicted protruding from the anterior segment 30. In order to post the longitudinal pull-out wedge 32 it again to take back in anterior segment 30, is provided by the spacer sleeve 36 and resting on her return spring 34.

Due to the pull-out wedge 32 converge both roller 38 and thereby both of the clamping jaws 31, which, as already described with reference to figure 2, is fixed on Cams or pins 42.

With reference to figa-3G schematically the process according to the invention.

At figa both sponge 31 ticks shown in the initial position, i.e. distant from each other by a distance A. Due to actuate the clamping jaws 29 both clamping jaws 31 converge, as shown in figb. Using opravlyaushi-measuring and control device, you can enter the command after processing the clamping ring or clamp the two clamping jaws 31 converge to a finite distance b. However, you can also enter the passed two clamping jaws 31 path, i.e. the value of a-b.

Due to compression, for example, zone 35 ear sage the nogo ring or clamp 33 with eyelet, as shown in figv, created, of course, return or clamping force, which acts on both of the clamping jaws 31. In the initial state, as shown in figv, effort K1, acting through the lug 35 on both the clamping jaws 31, is almost equal to zero.

By compressing both clamping jaw 31 eyelet 35 is deformed or clamping ring 33 is compressed so that the hose is firmly on the yoke. Due to this compression lugs 35 occurs, however, the return force K3, which is created by the deformation and, in particular, the clamping action of the clamp 33 on the outer surface of the hose (not shown). It is important that both the clamping jaws 31 converge as long as the distance between them is set on opravlyaushi-measuring and control device is not equal to b. Then additionally measure the return force K3 and compare with the input device 1 specified value 13. If the value of b (or a-b) and the value of K3 coincide with the respective preset values of 3 and 13 within fields 5 and 15 tolerances, the process of pressing or squeezing implemented successfully. In other words, you assume that have, for example, on the nipple or pipe hose placed or swaged in accordance with the set quality norms flawlessly. This, of course, always provided that the used pipes or nipples and hoses also meet a need for the consistent quality standards that is, as material, and calculation of connected or obitaemyh materials comply with certain rules.

Finally, you can type in memory measured during compression or squeezing of the actual value, as the underlying process set value, and to use in this ongoing process. So, you can at a later time to determine made if perfectly the process of clamping or compression or not. Preferred would be, of course, if it were possible to immediately report incorrectly implemented processes clamping or compression, or make them visually or acoustically noticeable, so you can immediately be excluded from the production process, this lack of connection, or the process of clamping or compression.

Figure 4 in the enlarged view shown opravlyaushi-measuring and control device of figure 1, i.e. different knob and indicators are seen better. For example, the set value 3 you can set the distance b, the initial position and the jaws 31 ticks, and also the so-called position a’ fixation, in which, for example, depicted in FIGU clamping lug 35 may already be fixed. This locked position is important, particularly in robotic processing, when the robot arm, comprising a pipe gripping pliers, with the achala takes from a shop for eyelet 35 clamp 33, moves the clamp 33 due to its rotation, and puts on a pipe or hose, which again automatically put on the nipple or other pipe is then automatically carried out are described according to the invention the process of placing a clamping ring or clip. In conclusion, the robot arm again automatically turns back for further processing.

For all three set of predefined values 3 you can set the tolerances. Besides setting the values of the tolerances provided by one indicator 7, which shows whether the entered preset value or not. Indicator 9 shows the value measured on the clamping ring or clip. Handles 11 settings you can set the speed of compression, i.e. the speed with which advances a wedge 33 to actuate both the clamping jaws or clamping wedges 31. Respectively you also can customize, which allows you to set the re-opening or removal of the clamping wedge 32.

As already explained with reference to figure 1, you can enter setpoints 13 achieved or established efforts, and can be set to be reached in the end clamping force K3 as the maximum applied during clamping swaging force. You can also assign the admission is through indicators 17 to determine whether the actual values specified. The actual value is also displayed on the indicator 19.

Further, the device comprises a handle 21 settings that can be set, i.e. begins when mounting the intermediate phase commit or do directly pincer movement from distance a to distance b.

Finally, the indicator 23 indicates complete the whole process of clamping or compression is successful or unsuccessful.

On the rear side of the device 1 provides a plug connector 24, which can be located 25 and the pressure control line 27. This plug connector 24 or the corresponding plug can be encoded, so that when the entered set values to the device 1 can be connected only matching these preset values clamping pliers.

Figure 5 in the form of a diagram depicts the process of clamping or compression, and the curve 51 indicates the path of ticks during installation, and curve 53 - clamping force generated between the pincers clamping or compression ring. In the area of R is the clamping or compression lugs 35, as shown in FIGU-g both sponge 31 ticks are shown in figure 5 the path until both the edge of the mites will not converge, for example, up to 2.5 mm, Then the process is interrupted, and simultaneously in this region R is also measured component 53 effort is well seen, the emergence of a force when clamping is slightly slow, i.e. upon reaching a distance of, for example, 2.5 mm final clamping force has not yet been achieved. Finally, there is a clamping force, for example, 1,0 kN, which is then compared to the corresponding specified value in the device 1. In the case that both values are within the required tolerance, the process of installation is estimated as completed successfully.

In depicted in figure 1-5 devices, clamping and crimping tools, it is of course only examples, which should serve for a more detailed explanation of the present invention. In principle, we are talking about any form of mechanical locking or fastening means, and characterized according to the invention the apparatus and method are specifically designed to accommodate clamps, clamping rings, crimp rings, clamps, bands bundles of cables, etc. In this connection, it should, among other things, to refer to the clips described, for example, in European patent No. 570742, 591648, 503609 and patents Switzerland No. 561383, 555026, 669642 and 677010. Clips with loops and without it is known also from many other patents. In relation to the ferrule should, inter alia, refer to patent Switzerland No. 679945 and European patent No. 543338.

In respect of the principle of operation of clamping jaws should refer to Europe is iski patent No. 591648.

The described device is possible, a controlled and adjustable placement, clamping and compression all fixing and fastening means, and the actuator may be pneumatically, hydraulically, and electromehanichesky. In regard to measurement technology, sensor technology, e-governance, etc. should also be mentioned that it is on conventional known technique and knowledge, which are not described in detail here.

In conclusion it should be stated as an example of the operation of ticks for clamps with eye, as it can be chosen in conjunction with clamping tongs in figure 1-4.

Stationary electro-pneumatic pliers, based on the clamping pincers 29, depicted in figure 1, equipped with sensors and electronics for control and evaluation, in order to adjust with the possibility of installing physical quantities provisions of the clamping movement of the clamping and effort.

Registered physical values can be compared with set values 1 (figure 1 and 4), and on the basis of comparison can be obtained evaluation information.

For example, a stationary pneumatic pliers have a cascade of higher priority control path and slave control efforts. Regulation efforts mites it is the indirect regulation based on the control pressure, because the effort ticks = f (inlet pressure x area of the cylinder).

In the initial state and, as shown in the example on figa, position disclosure mites can take over the control loop path any arbitrary position. The optimum condition occurs when the position disclosure ticks slightly larger than the lug 35 of the clamp 33. From this position can be selected from two modes of compression loops.

1. The compression in the compression with asking installed crimp efforts. After operation of the pliers are closed in accordance with their given speed of the provisions and disclosures in the position b of the compression.

The regulation circuit of effort controls in each moment of time characteristic of effort and prevents exceeding the maximum value. If the maximum force is reached, then either continue the compression with this effort until it reaches the prescribed path, or, if this is not possible, ticks stop in its position. If the specified force is not achieved, then the pliers are closed in a state of compression.

2.1. Stop with fixing clamp and’ eye with adjustable clamping force.

2.2. The compression in the compression with asking installed crimp efforts. After tripping and’ pliers are closed in accordance with their given speed of the ogene disclosure ticks to position and hold.

This locked position is not a specified value, and occurs upon reaching the locking efforts, which should be such that it recorded the eye, without deforming it.

Following actuation closes his pliers in accordance with their given rate of position fixing in position b of the compression.

The regulation circuit of effort controls in each moment of time characteristic of effort and prevents exceeding the maximum value. If the maximum force is reached, then either continue the compression with this effort until it reaches the prescribed path, or, if this is not possible, ticks stop in its position. If the specified force is not achieved, then the pliers are closed in the position b of the compression.

Optimal compression is achieved when the eye has reached the appropriate parameter table position compression with application specific crimp efforts.
