[0002] The inner ring of the bearing is one of the main parts of the bearing. After the inner ring of the bearing is processed, it needs to go through a grinding process to remove burrs on the inner ring of the bearing. The outer surface of the inner ring of the bearing is processed with an annular groove for storing balls. During the grinding process of the inner ring of the bearing, the annular side surface of the inner ring of the bearing, the two sides of the inner ring of the bearing, and the inner wall of the annular groove on the inner ring of the bearing need to be ground. When the inner ring of the bearing is ground with a motor-driven grinding disc, the relative position of the inner ring of the bearing and the grinding disc needs to be adjusted multiple times because the grinding disc is a disc-shaped structure, which reduces the grinding efficiency of the inner ring of the bearing. Therefore, it is necessary to design a bearing inner ring processing equipment that improves the grinding efficiency of the inner ring of the bearing. Utility Model Content
