Description

Technical Field

[0001] The invention relates to the technical field of bearing outer ring polishing, in particular to a polishing device for bearing outer ring processing. Background Art

[0002] During the processing of the outer ring of the bearing, some surface defects may be generated, such as processing lines, burrs, tiny cracks, etc. These defects will become stress concentration points. When the bearing is under load, it is easy to cause the cracks to expand and eventually cause bearing damage. Polishing operation can effectively remove these surface defects, make the outer ring surface more uniform and complete, enhance the fatigue resistance of the bearing, and extend its service life.

[0003] A patent application with application number CN202020284156.8 discloses a bearing outer ring polishing device, including a processing table, wherein two adjustment grooves are provided on one surface of the processing table, and sliders are slidably connected to the inner walls of the two adjustment grooves. Electric push rods are fixedly installed on the side surfaces of the processing table and at positions corresponding to the adjustment grooves, and the movable ends of the two electric push rods extend into the corresponding adjustment grooves and are fixedly connected to the corresponding sliders.

[0004] In summary, when polishing the outer ring of the bearing, if the fixture of the polishing equipment cannot accurately fix the outer ring of the bearing, causing the outer ring of the bearing to shake during the polishing process, some areas will be over-polished and some areas will be under-polished. This will not only have an adverse effect on the surface quality and dimensional accuracy of the entire outer ring, but also reduce the qualified rate of the finished product of the bearing outer ring in the polishing process.
