Abstract

The invention relates to machine-assembly production, namely to devices for assembling a shaft with a hinge (W). The aim of the invention is to increase the reliability of the assembly. This is achieved by supplying the device with a lock ring orientation mechanism (CK), which eliminates the possible displacement of the latter in the horizontal plane and avoids their jamming.

Description

The invention relates to machine-assembly production, and in particular to devices for assembling a shaft with a hinge, for example, a drive shaft of a vehicle's front wheels. The aim of the invention is to increase the reliability of the assembly.

FIG. 1 shows the device, about the PSY view (nodes I and I, which explain the position of the locking rings after the final assembly of the shaft); in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - section B - B in FIG. 3 (which explains the sequence of assembling a drive shaft with a hinge).

The device comprises a drive shaft 1, on which the stop rings 2 and the stop rings 3 are installed, the outer hinge 4 with the inner race 5, the ferrule 6 of the inner hinge.

The device consists of the following nodes; frame 7, shaft 8 press-in mechanism with 1 hydraulic cylinder 9, at the end of the stem of which there is a punch with collar 10, mechanism for testing locking rings 11 with spring-loaded two-shoulder grippers 12, hinge mounted on a movable platform, prisms 13 with spring-loaded grippers 14, devices for hinge fixation 15 with clamps 16, kinematically connected with hydraulic cylinders 17, spring-loaded slider 18 spring loaded with a predetermined force (FIG. 2) with a finger 19, kinematically connected with hydraulic cylinder 20, retaining ring orientation mechanism

22 and hydraulic cylinders 23. Jaws 24 are connected with sponges 25 and 26, on which semi-rings 27 are mounted, with a taper 28, a cylindrical surface 29 and a centering ridge 30. The slider 18 is installed in the guide cylinder 31. The control panel and the hydraulic station do not are shown.

The device works as follows.

In the initial position, the hydraulic cylinder 9. Of the pressing mechanism 8 slightly does not reach the extreme upper position; the spring-loaded two shoulders grips 12 of the mechanism for testing the locking rings 11 are divorced; the clamps 16 of the fixation device for the hinge 15 are separated by hydraulic cylinders 17, and the slider 18, spring-loaded with a predetermined force, is held in the lowest position by the hydraulic cylinder 20; the movable jaws 25 and 26 of the device for orientation of the locking rings 21 are separated by a hydraulic cylinder 23.

The hinge 4 with the inner race 5 is manually installed into the slide 18 spring-loaded with a predetermined force. The control buttons of the orientation of the snap rings 21 are pressed. The movable jaws 25 and 26 with the orienting half-rings 27 are reduced by the action of the hydraulic cylinder 23 and occupy the position above the outer 4 hinge. how

only the jaws 25 and 26 are connected, the hydraulic cylinder 20 automatically activates and the slider spring-loaded with a predetermined force, together with the outer hinge, emerges before contact with the centering 30, orienting the semiring 27. After the inner race 5 of the outer hinge 4 comes into close contact with the orienting half rings 27 allowed to install the drive shaft.

The drive shaft 1 with retaining rings 2 and retaining rings 3 assembled on it is installed in a prism 13 with spring-loaded grippers 14 and guided by the splines of the inner race 5, pro, pushing the shaft manually through the lead-in cone 28 and the cylinder 29 of the orienting half-rings before the retaining ring with internal clip slots.

After the lower end of the drive shaft is oriented, its upper end

0 set the clip 6 and orients it along the slots and retaining ring. After finishing the shaft preparation for assembly, turn on the control button. “Start-up is located on the control panel. With the inclusion of control buttons "Start automatic

5, the hydraulic cylinder 9 is actuated. As the pressure increases from the side of the hydraulic cylinder 9 to the holder 6, the drive shaft 1, the outer hinge 4 and the spring-loaded slider 18 move downwards. When the slider and the entire assembly is moved downward, the outer hinge releases the orienting half rings 27, and when the finger reaches the end switch 19, the hydraulic cylinder 23 is activated, the jaws 25 and 26 open, and the drive shaft with the stop ring 3 passes. As soon as the spring-loaded slider 18 reaches the extreme the lower position, the drive shaft 1 is pushed all the way with the holder 5, and the holder 6 to the stop ring. After the exposure time has expired, the hydraulic cylinder 20 is activated and locks the spring-loaded slider in the lower position.

Simultaneously with the inclusion of the hydraulic cylinder 20, the hydraulic cylinders 17 are activated, the clamps 16 cover the outer hinge 4 and hold it. As soon as the clamps 16 securely fix the outer joint 4,

5, the hydraulic cylinder 9 is actuated and the punch with the flange 10 rises, grasping the small shoulders of the spring-loaded two shoulders grips 12. The grips are turned until the hooks of the large shoulders of the two shoulders grips 12 do not catch the clamp 6 and do not pull it with a certain force. After the holding time has expired, the hydraulic cylinder 9 switches and the punch with the collar 10 retracts, the spring-loaded two shoulders gripping the sides and one of them acts on the limit switch.

After that, the hydraulic cylinder 9 stops its work, the hydraulic circuit works.

Lindra 17, clamps 16 release outboard hinge 4 from retention. The assembly is removed from the installation. This ends the work cycle. In the event that the drive shaft 1 is pulled out of the outer hinge 4 or the cage 6 is removed from the drive shaft 1, a red lamp on the control panel lights up, indicating the assembly is defective.
