Assembly fixture for wire retaining rings for rear drive axle half shafts

This invention relates to the field of rear drive axle assembly technology, and more particularly to an assembly fixture for a wire retaining ring for a rear drive axle half-shaft. The fixture includes an assembly sleeve containing a cylindrical wire retaining ring placement groove and a cylindrical clearance groove, the latter communicating with the bottom surface of the placement groove. During assembly, the wire retaining ring is first placed in the placement groove. Then, the assembly fixture with the wire retaining ring is aligned with the half-shaft end face. Next, the second end of the assembly sleeve is pressed or struck, causing the wire retaining ring and the assembly sleeve to expand outwards by the half-shaft. Finally, after the wire retaining ring moves into the half-shaft groove, it retracts and returns to its original position. Using this assembly fixture, the wire retaining ring only needs to expand to the outer diameter of the half-shaft to complete the assembly, effectively reducing the possibility of the wire retaining ring failing to retract and return to its original position, thus improving the assembly quality stability of the wire retaining ring.
