Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a press-fitting fixture for a shaft head and axle housing assembly. Background Technology

[0002] In the automotive manufacturing industry, the assembly accuracy of the axle head and axle housing assembly directly affects the overall performance and safety of the vehicle. Traditional axle head press-fitting processes typically employ fixed tooling, using manual labor or simple mechanical devices for positioning and pressing. However, due to the complex structure of the axle housing and axle head, and the need to ensure high coaxiality and angular accuracy during assembly, traditional tooling often fails to meet production requirements, leading to low assembly efficiency, unstable accuracy, and even problems such as incorrect assembly or omissions.

[0003] In existing technologies, while some press-fitting fixtures utilize V-blocks for positioning, they typically lack flexible angle adjustment capabilities, making it difficult to adapt to the assembly requirements of shaft heads of different models or specifications. Furthermore, the unreasonable layout of adjustment blocks in traditional fixtures can easily lead to shaft head misalignment or tilting during press-fitting, affecting assembly quality. Simultaneously, the lack of effective error-proofing mechanisms makes assembly errors prone to occur during operation, increasing rework rates and production costs. Utility Model Content
