Universal joint shaft sleeve and clamp spring synchronous pressing-in device

Abstract

The invention discloses a universal joint shaft sleeve and clamp spring synchronous press-in device. The universal joint shaft sleeve and clamp spring synchronous press-in device mainly comprises a pressing head, a partition plate, a conical guide sleeve, a cross shaft supporting rod, a part supporting rod and a base, wherein one end of the pressing head is connected with press-fitting equipment, the other end of the pressing head is matched with the conical guide sleeve in the press-in process, the cross shaft supporting rod is coaxially arranged below the pressing head, the part supporting rod sleeves the cross shaft supporting rod, one end of the part supporting rod is inserted into the base, and the other end of the part supporting rod is used for supporting a part; and a cross shaft is inserted into one end of the cross shaft supporting rod, the other end of the cross shaft supporting rod is inserted into a shaft sleeve, and the shaft sleeve is inserted into the conical guide sleeve. The shaft sleeve and a clamp spring can be installed in place at a time, and use of clamp spring pliers is eliminated; the shaft sleeve is installed in place at a time, and the situation that one shaft sleeve is excessively pressed in before is eradicated; and by adopting the universal joint shaft sleeve and clamp spring synchronous press-in device, the productivity is improved by 15%, and the potential quality hazard caused by deformation due to the fact that the shaft sleeve moves in an earhole after being excessively pressed in is eliminated.

Description

technical field [0001] The invention relates to the field of universal joints, in particular to a synchronous press-in device for a shaft sleeve of a universal joint and a circlip. Background technique [0002] The assembly of the existing universal joint in the workshop mainly includes the following steps: the first step, place a flange fork on the backing plate with the left hand, put the bushing into the ear hole of the flange fork with the right hand, and press the bushing in by stepping on the switch. ; In the second step, turn the flange fork 180°, put the cross shaft of the universal joint into the flange fork; in the third step, put a bush on the flange fork, step on the foot switch to turn the bush Press into the flange fork; Step 4, step on the foot switch to press the bushing into the ear hole of the flange fork until the circlip groove is fully visible; Step 5, use the circlip pliers to put the circlip into the groove; The sixth step is to turn the flange fork 1...

AI Technical Summary

Problems solved by technology

In the existing assembly method, the shaft sleeve is pressed in by a press, and the circlip is manually clamped into the circlip groove by a caliper, so the operating skills and physical strength of the operator are relatively high.

In addition, because the shaft sleeve and the circlip are installed in two steps, the production efficiency is low. During the press-fitting process, the shaft sleeve will be pressed into the position where the circlip groove completely leaks out, but the shaft sleeve will be over-pressed during the actual operation. As a result, when the second bushing is pressed, the first bushing moves through the extrusion force of the cross shaft, causing the bushing to deform
