Comprehensive polishing device for automobile brake disc Technical Field The invention relates to the technical field of automobile part machining, in particular to a comprehensive polishing device for an automobile brake disc. Background With the rapid development of the automobile industry to high performance and high safety, a brake system is used as a core safety component, and more stringent requirements are put on the machining precision and the surface quality of a brake disc. The surface flatness and the side smoothness of the brake disc directly influence the friction force stability, the heat dissipation efficiency and the service life during braking, and the processing quality of the brake disc directly relates to the running safety of a vehicle. In the field of automobile manufacturing and after-sales maintenance, brake disc polishing is a key process for guaranteeing performance of the brake disc, and comprehensive and fine machining of surfaces and side surfaces is required. Currently, automotive brake disc grinding equipment is mainly divided into two categories. One type is traditional single-module polishing equipment, and polishing of the surface and the side face of a brake disc is completed sequentially through a single grinding head, and the position and polishing parameters of the grinding head are manually adjusted. The other type is a semiautomatic polishing system, which is provided with a simple moving mechanism, can partially reduce manual intervention, and still adopts fixed polishing parameter operation. Both types of equipment take basic grinding of a brake disc as a core target, and the synchronous processing and dynamic adaptation requirements of multiple parts are not fully considered. However, there are significant limitations to the prior art. Traditional single module equipment inefficiency of polishing, surface and side ordered processing lead to the cycle overlength, and manual adjustment easily causes polishing precision inequality, is difficult to satisfy the batch production demand. While the semi-automatic system improves part of efficiency, the real-time perception of key parameters such as temperature, roughness, clamping pressure and the like in the grinding process is lacking, the fixed parameter operation is easy to cause over-grinding, under-grinding or thermal damage of a brake disc, meanwhile, the double-part grinding lacks independent motion control, the track is easy to interfere, the dust collection and safety protection integration level is low, the working environment is influenced, potential safety hazards exist, and the requirements of modern automobile industry on high-precision, high-efficiency and high-safety grinding cannot be adapted.
