Description

Technical Field

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

[0002] Bearings are important mechanical parts that support mechanical rotating bodies, reduce the friction coefficient during movement, and ensure their rotation accuracy. To ensure the accuracy and performance of bearings, the raceways of bearings need to be super-finished before leaving the factory to meet the requirements for the surface roughness of the bearing raceways.

It includes a polishing truncated table, a bracket arranged on the polishing truncated table, and a motor arranged on the bracket. The polishing truncated table is provided with a positioning member, and the positioning member includes a positioning column and a plurality of positioning shafts for positioning the bearing outer ring. The positioning column is arranged at the center of the polishing truncated table, and the positioning shafts are evenly spaced and arranged on the outer peripheral surface of the positioning column; a polishing wheel is arranged on the output shaft of the motor, and a spacing for accommodating the bearing outer ring is formed between the polishing truncated table and the polishing wheel;

[0004] The device is convenient for simultaneously mounting multiple sets of bearings on multiple positioning shafts by setting several sets of positioning shafts, and then the outer rings of multiple sets of bearings can be polished at the same time. However, the following defects still exist: the multiple sets of positioning shafts on the device are welded to the outside of the positioning column, and the bearings are mounted on the outside of the positioning shafts and polished by the polishing wheels above. Therefore, the inner diameter of the bearing needs to be slightly larger than the outer diameter of the positioning shaft. When the inner diameter of the bearing is much larger than the outer diameter of the positioning shaft, the outer rotation of the bearing positioning shaft becomes unstable when the polishing wheel polishes the outer ring of the bearing. Therefore, the welded positioning shafts are only suitable for bearings with the same inner diameter, which makes it impossible for the device to polish the outer rings of bearings of different sizes.
