Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing devices, and in particular to a center bearing grinding and polishing device and a use method thereof. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support the mechanical rotating body and reduce its friction coefficient during rotation, thereby ensuring the normal operation of the mechanical equipment. Bearings are mainly composed of inner and outer rings and middle rollers. Bearings need to be polished during the production process to reduce their friction during use. Therefore, existing bearings need to be polished with a grinding device during the production process. However, there are still some problems with the existing grinding devices, as follows:

[0003] The existing grinding device can only be used to grind a single outer ring or inner ring of a bearing when in use. Moreover, since there is a groove between the inner and outer rings of the bearing for placing the roller, the existing grinding device cannot perform a good grinding on the groove part. Moreover, the existing grinding device cannot be well adapted to grinding bearings of various sizes, which limits the use scope of the grinding device. At the same time, the existing grinding device cannot collect the metal debris produced by grinding in time during use, which leads to metal dust polluting the processing environment and also affects the health of the workers.
