Description

Technical Field

[0001] The utility model relates to the technical field of assembly tooling, in particular to an assembly tooling for a wet clutch spring retaining ring. Background Art

[0002] As a standard part, circlips are widely used in the machinery industry. According to their uses, they can be divided into circlips for shafts and circlips for holes. According to their structural forms, they can be divided into circlips without ears and circlips with ears. Among them, circlips for shafts are also called shaft clamps and external clamps. They are used to fix the axial movement of parts and prevent unnecessary axial movement of bearings.

[0003] The wet clutch requires an elastic retaining ring for the assembly shaft. Due to the particularity of the clutch structure, the spring covers the retaining ring slot. For this reason, it is necessary to design and manufacture a set of special assembly tools to assemble the retaining ring into the slot while pressing down the clutch spring to expose the slot.

[0004] The existing assembly method is to use a press to press the clutch spring down to expose the retaining ring assembly slot, and then the worker reaches under the press to install it with circlip pliers. However, this assembly method takes a long time to adjust, has low assembly efficiency, and cannot meet the production line production rhythm. In addition, during the operation of the press, the worker reaches under the press to assemble, which does not comply with the press safety operation specifications and poses a safety hazard. Therefore, it needs to be improved. Utility Model Content
