Description

Technical Field

[0001] The utility model relates to the field of mechanical processing equipment, in particular to an axle housing clamping tool. Background Art

[0002] The axle housing is the base upon which the final drive, differential, axles, and wheels are mounted. Its primary function is to support and protect these components. Generally speaking, the axle housing of a conventional non-disconnecting drive axle is a rigid hollow beam supported by the left and right drive wheels. The final drive, differential, axles, and other transmission components are housed within it. The axle housing is connected to the vehicle frame or carriage via longitudinal leaf springs. It is a crucial component of the drive axle and a key component of the running system.

[0003] At present, when cutting, grinding, welding and other processing are carried out on automobile axle housings, fixed tooling is required for clamping. Drive axle housings can be structurally divided into three categories: integral axle housings, separable axle housings and combined axle housings, with different shapes. The fixing effect of traditional fixed tooling is not ideal. Not only is the operation cumbersome, but it is easy to loosen after fixing, affecting the processing and resulting in poor processing quality. This is an existing problem. Utility Model Content
