Description

Technical Field

[0001] This invention relates to the field of bearing outer ring polishing technology, specifically to an adaptive polishing device for bearing outer rings and its usage method. Background Technology

[0002] The polishing precision of the bearing outer ring is one of the key factors affecting bearing quality. If the polishing precision is not up to standard, defects such as roughness, ripples, and scratches will appear on the bearing surface. These defects will increase the bearing's frictional resistance and reduce the bearing's rotational accuracy and service life.

[0003] The polishing gloss of the outer ring of a bearing is an important factor affecting the appearance quality of the bearing. If the polishing gloss is insufficient, the bearing surface will appear dull and lack luster, which will affect the aesthetics of the bearing.

[0004] In the process of polishing bearings, when polishing bearing outer rings of different diameters, the polishing equipment needs to be adjusted to different positions to ensure stable polishing of the bearing outer ring. However, existing polishing equipment requires not only adjusting the position of the polishing equipment but also adjusting the dimensions of the bearing conveying structure when polishing bearing outer rings of different diameters, which is quite cumbersome. Therefore, to address the above problems, an adaptive polishing device for bearing outer rings and its usage method are proposed. Summary of the Invention
