[0003] For example, the existing Chinese patent CN109202621 A discloses a grinding device for processing the inner raceway of a bearing, which is fixedly connected to the surface of a slider with a short rod, one end of the short rod penetrates the telescopic sleeve and extends to the outside of the telescopic sleeve, and the surface of the telescopic sleeve is provided with a slide groove adapted to the short rod, and one end of the short rod is fixedly connected to the outside of the telescopic sleeve with a push block, and by setting a push block on the outside and using the short rod to push the internal slider to move, the brush head can be conveniently pulled toward the center, so that it is convenient to place it in the inner raceway, and the operation is more convenient. Although the above device can clean the iron filings after grinding the surface of the inner raceway of the bearing, and use the magnetism of the magnetic ring to adsorb the iron filings to the surface of the iron sheet for collection, it can avoid the problem of iron filings flying around and causing inconvenience in cleaning, but it lacks the function of fixing the bearing when processing the bearing, and it is not easy to adjust the grinding position and angle during processing, resulting in poor flexibility of the processing equipment.
