Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a bearing ring processing clamp. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The bearing ring refers to the outer ring and the inner ring. The outer ring is the external annular part of the bearing, usually made of metal, and its surface is ground and polished to provide a fit with the seat. The outer ring cooperates with the inner ring and the balls to provide external support and fixation for the bearing. The inner ring is the internal annular part of the bearing, also usually made of metal. The surface of the inner ring is also ground and polished to provide a fit with the shaft. The inner ring rotates on the shaft by contacting the rolling elements, bearing and transmitting axial and radial loads. These two parts work together to form the basic structure of the bearing to support and transmit the load on the shaft, reduce friction, and enable the bearing to run smoothly.

[0003] When the bearing ring is being produced and processed, it is necessary to clamp and fix the bearing ring. However, when the current processing fixture is used, the bearing ring is mostly clamped and fixed directly through the clamping plate. Although this method is easy to operate and convenient for clamping bearing rings of different sizes, the connection between the clamping plate and the bearing ring is in a processing blind spot. Therefore, during processing, the bearing ring needs to be disassembled and clamped many times to complete the processing operation, which is rather troublesome. In view of the above problems, the inventor proposes a bearing ring processing fixture to solve the above problems. Utility Model Content
