Press-fitting device for roller pin check ring for tripod ball

Abstract

The invention discloses a press-fitting device for a roller pin check ring for a tripod ball. The press-fitting device mainly comprises a pressing-in device, a check ring compression device and the like; a driving device is installed above a frame top plate of a frame; the lower end of the driving device is connected with and drives the pressing-in device to do vertical reciprocating motion alongthe axis thereof; one end of a transition shaft of the pressing-in device is connected with a piston rod of the driving device, and the other end of the transition shaft is connected with a pressing head; the pressing head is sleeved with a pressing sleeve; a guide column and the transition shaft are connected by an anti-rotation plate so as to limit the pressing-in device to only move in the axial direction; a fixed substrate is fixed onto a frame base; the check ring compression device is placed on the fixed substrate; and the check ring is placed in the check ring compression device. The press-fitting device avoids the bad conditions that the check ring seriously deforms, a port is overlapped and the like when the check ring is entirely pressed down, reduces the risk of plastic deformation of the check ring, effectively protects the assembly mating state of the check ring and an outer ring, can well protect the check ring and the press-fitting device, reduces the labor intensity andcost of a worker, and improves the automation degree and production efficiency.

Description

technical field [0001] The invention relates to the field of three-ball pins, in particular to a press-fitting device for three-ball pin roller retaining rings. Background technique [0002] The retaining ring is a part that is compressed by an external force during assembly, expands to recover part of the deformation after being installed in the card slot, and achieves a good positioning function. The three-ball pin roller retaining ring is used for the axial limit of the outer ring and the needle roller. The existing technical solution is to manually break the retaining ring into a vertically staggered state, place it in the original retaining ring compressing device 101, and then use the automatic retaining ring pressing device with a flat indenter 102 to press the retaining ring into the outer The retaining ring is press-fitted in the ring slot. The retaining ring is pressed with a flat indenter. Because the force of the operator's hand is not uniform, if the force is ...

AI Technical Summary

Problems solved by technology

The retaining ring is pressed with a flat indenter. Because the force of the operator's hand is not uniform, if the force is too large, the retaining ring will be scrapped because it cannot spring back freely; It is easy to appear that the whole retaining ring is pressed down to the card slot at the same time, so that the two ports at the fracture overlap together, resulting in serious elastic deformation of the retaining ring and being blocked in the retaining ring compression groove or forced into the retaining ring card slot. The thickness of the retaining ring at the overlap is greater than the width of the card slot, and the retaining ring is difficult to be inserted into it, and it will rebound under the action of the elastic force, which will cause the retaining ring to be scrapped and damage the press-fitting device

Secondly, the amount of assembly of the three-pin retaining ring is large, and manual breaking of the retaining ring will cause excessive labor intensity and low press-fit efficiency
