Technical Field
[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for an integrated cast bridge housing of a commercial vehicle. Background Art
[0002] The bridge housing is the assembly base for the main reducer, differential, half-shafts and wheels. Its main function is to support and protect the main reducer, differential and half-shafts. Generally speaking, the bridge housing of an ordinary non-disconnecting drive axle is a rigid hollow beam supported on the left and right drive wheels. The main reducer, differential, half-shafts and other transmission parts are installed in it. The bridge housing is connected to the frame or carriage through longitudinal leaf springs. It is an important component of the drive axle and one of the main components of the running system. Therefore, it plays a large role in the production of machine parts.
[0003] At present, the production and processing of special-shaped bridge housings involves the processing and polishing of the finished bridge housings to ensure product quality. Usually, the finished bridge housings are fixed on a grinding bed and polished by a grinding mechanism. However, the waste chips generated during grinding cannot be effectively collected, which makes the workbench surface dirty and brings trouble to subsequent cleaning. At the same time, during the grinding process, it is impossible to quickly adjust according to the different sizes of bridge housings, which affects the grinding efficiency. For this reason, we propose a grinding device for integrated cast bridge housings of commercial vehicles. Utility Model Content
