The invention relates to a device for pressing one part to another and can be used for the Assembly of machines and mechanisms.

A device for pulling the parts and quality control fitting, comprising a slide provided with drive reciprocating movement and connected with the slide rod, a supporting tool for the shot and made two stops, the rod is installed with vozmogla of the known device is complicated, because you want a separate drive for movement of the slide, and does not provide sufficient strength when determining the quality of crimp, which is required, for example, when the pressing cylinder liner in the cylinder axial piston hydraulic machines, as these sleeves when working hydraulic machines are always subject to axial pressure working environment. Lack of precision is due to the fact that the quality control offset is calibrated spring, the parameters of which vary and depend on the quality of the spring itself.

The basis of the invention is to create a device for pulling the parts and quality control fitting, which would be simpler design and improved control over the quality of the crimp.

The problem is solved in that in the known device for pressing containing the slider to the actuator reciprocating movement and connected with the slide rod, a supporting tool for the shot and made two stops, the rod is installed with the possibility of axial movement relative to the slide bar and interact with stops according to the invention, the actuator reciprocating peremeshheniem, located on both sides of the piston.

Thus, by performing the drive reciprocating movement in the form of a cylinder, and the function of the slider is aligned with the function of the piston of the hydraulic cylinder, it is possible to simplify the device, eliminating the need for additional hardware calibrated spring), the loading rod effort to control the quality of the pressing, the function assumes the working fluid, and the force more accurately and stably, as it depends only on the diameter of the rod, which remains constant.

To reduce leakage of the working fluid in the device, you must also rod in the coupling zone with the piston to equip at least one seal.

It is also useful to improve the performance of the piston of the power cylinder to equip at least two additional rods.

The drawing shows the device in longitudinal section.

Device for mounting parts, such as bushings in the cylinder axial piston hydraulic machines, contains mounted on the frame 1 column 2, fastened in the upper part of the head plate 3 made in the form of a plate. On traverse 3 is what about the feature evenly spaced around the circumference of the rod 6 with the tool 7 for pressing sleeves 8 through conductoras plate 9 in the cylinder block 10.

This number of rods 6 to provide smooth movement of the piston 5 without distortions in the power cylinder 4 and increase the number of simultaneously injected bushings 8.

The rod 6 is installed with the possibility of axial movement relative to the piston 5 and is equipped with lugs 11 and 12, arranged on the rods on both sides of the piston 5. The distance L between the lugs 11 and 12 is greater than the thickness S of the piston 5.

The rods 6 in place mates with the piston 5 to reduce leakage of the working fluid include at least one seal 13.

Column 2 opposite each of the rods 6 are installed end sensors 14.

The device operates as follows.

In conducting plate 9 load sleeve 8 and is served in the piston cavity 15 of a cylinder working fluid, under the action of the pressure which the piston 5 moving down, rests on the lugs 11 on the rod 6 and through tools 7 supressive sleeve in the cylinder block 10 to the stop of the piston 5 in the yoke 3. Further, because the rod 6 is movable in the axial direction relative to the piston 5, due to the fact that the distance L between the lugs 11, 12 is greater than the thickness S of the piston 5, the bushings and will be accompanied by Kee the river cross-section of the rod 6 in place mates with the piston 5.

If further with this testing effort of the sleeve 8 does not move in the bores of the cylinder block, the quality control of completed pressing and forging a connection block with bushings recognizes fit.

If any of the bushings 8 and then will move in the cylinder block 10, the end face of the shaft 6 abuts against the end of the sensor, which sends a signal to the rejection.

Further, when the supply of the working fluid in the rod cavity 16 of a cylinder, the device returns to its original state.

Thus, the rod is loaded by the control pressure of the working fluid and not a spring, which greatly simplifies the design of the device, with the effort to control the quality of the shot more accurately and stably, which improves control over the quality of the crimp.
