Abstract

The invention relates to riveting and assembly work, in particular to devices for riveting roller bearing cages. The purpose of the invention is to improve the quality, reduce energy costs and expand technological capabilities. The device includes a housing 1 on which a riveting stamp is mounted, including the lower riveting tool (NCI) 3, the spring-loaded cradle 4 and the upper riveting tool (CRI) 5. The actuator of the AWI is made in the form of two sliders (P) - the bottom 6 and the top 7. The latch is connected with the FRI 5 and is made with an inclined surface. P 7 is made with the lever 11 and the roller 12, interacting with an inclined surface. The actuator includes a pneumatic cylinder 13 with a double-arm lever 14 and a roller 15. The pre-compression mechanism is made in the form of an additional pneumatic cylinder 19 connected by means of a rigid frame 20 with a FRI 5. The bearing 21 is mounted on a cradle 4. The FRI 5 is lowered onto the bearing by means of an pneumatic cylinder 19 to a height H and preloads the bearing to the NCI 3. In this case, both half separators are compressed between each other, P 6 and 7 are lowered down, P 7 are locked by means of a clamp. After that, the pneumatic cylinder 13 is turned on, which through the lever 14 with the roller 15, the lever 11 with the roller 12 transfers the force to П 6, which drives the FRI 5. 3 Cp f-ly, 3 ill.

riveting tool (FRI) 5. The actuator of the FRI is made in the form of two sliders (P) - the bottom 6 and the top 7. The clamp is connected to the FRI 5 and is made with an inclined surface. П 7 it is executed with the lever 11 and with the roller 12 interacting with an inclined surface. The power drive turns on the pneumatic cylinder for 13 s. two shoulders with lever 14 and roller 15. The pre-compression mechanism is made in the form of an additional pneumatic cylinder 19 connected by means of a rigid frame 20 with a FRI 5.

The bearing 21 is mounted on a bed 4. The FRI 5 is lowered onto the bearing by means of an air cylinder 19 to a height H and preloads the bearing towards NSI 3. Both half separators are pressed together, P b and 7 are lowered down, P 7 is locked by means of a clamp. After that, the pneumatic cylinder 13 is turned on, which through the lever 14 with the roller 15, the lever 11c with the roller 12 transfers the force to П 6, which drives the FRI 5. 3 Cp f-ly, 3 ill.

This invention relates to riveting and jointing works.

The aim of the invention is to improve the quality, reduce energy costs and expand technological capabilities.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same view in the process; in fig. 3 is a section A-A in FIG. 2

The device includes a housing 1 on which a riveting stamp is mounted, which includes a lower riveting tool 3 fixed on the housing plate 2, a spring-loaded cradle 4 for placing a riveted product on it and an upper riveting tool 5. The power rider of the upper riveting tool 5 is made in two with the possibility of axial movement of the sliders 6 and 7, mounted in the sleeve 8. The slide 6 is made with an inclined end surface and on it by means of an adjusting screw 9 with a lock nut 10 mounted upper riveting tool 5. On the upper slider 7 mounted lever 11 with two rollers 12 located on both sides of the lever and interacting with the inclined surface of the slide 6. In addition, the power actuator includes a power pneumatic cylinder 13 with two shoulders lever 14 with a roller 15 at the end . On housing 1, a retainer 16 is installed with a pneumatic actuator 17 and an emphasis 18. The pre-compression mechanism is made in the form of an additional power pneumatic cylinder 19 connected by means of a rigid frame 20 with a top riveting tool. Assembled bearing 21 mounted on the cradle 4.

The device works as follows.

The bearing 21 is oriented oriented on the cradle 4. The upper tip of the tool 5 is lowered onto the bearing

21 by means of a pneumatic cylinder 19 through the frame 20 to a height H (FIG. 2) and preloads the subsignator to the lower riveting tool 3, overcoming

the force of the spring of the lodgement 4. In this case, both half-separators of the bearing 21 are compressed between themselves (Fig. 3), which is a necessary condition for their high-quality riveting.

Lowering the upper riveting tool 5 by the pneumatic cylinder 19 allows, under its own weight, lowering to the lower position the sliders 6 and 7. At the same time, the end of the upper slide 7 is locked by a movable latch 16. After that, the pneumatic cylinder 13 is activated and through the double-arm lever 14 with the roller 15 transmits force to the lever 11 with the rollers 12 of the upper slider 7. The rollers 12, rolling on the inclined end surface of the slider 6, move the upper riveting tool 5 by an amount fy (Fig. 3), equal to the height of the deformable part of the rivet shank. As a result of the force action, a high-quality riveting of the bearing cage occurs.

Upon completion of the riveting process, the rod of the power pneumatic cylinder 13, the movable clamp 16 and the rod of the pneumatic cylinder return to their original position. When this pneumatic cylinder 19 raises to its original position through the frame 20, the upper riveting tool 5, the slider 6 and the upper slider 7. The device is ready for the next cycle of operation.
