Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing and relates to a grinding device, in particular to an outer surface grinding device for bearing ring processing. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearing rings are one of the main components of bearings. The raw material of bearing rings is cylindrical bars or tubes. During processing, long sections of bars or tubes are usually cut into multiple rings for production. Before cutting, the outer surface of the tube needs to be polished, usually with a polishing belt. During polishing, the polishing belt rubs against the outer surface of the bearing sleeve to complete the outer surface treatment.

[0003] However, the existing grinding devices usually grind by fixing both ends of the pipe. The distance between the fixed structures at the two ends is fixed, so that the grinding device can only grind blanks of the same length. In addition, the position of the grinding belt is fixed and it is inconvenient to adjust. The pipe can only be grinded at a fixed position. The grinding device has low applicability and reduces the grinding efficiency. Utility Model Content
