Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to a grinding tool for machining a groove of a bearing outer ring. Background Art

[0002] In the process of machining the outer ring groove of the bearing, the traditional grinding tool design often has problems such as low installation efficiency and insufficient machining stability. Specifically, the traditional grinding tool usually uses fasteners such as screws and nuts to connect the shaft and the grinding block. This connection method is not only cumbersome to install, but also requires a lot of time and manpower. In addition, it is easy to loosen or deviate during the machining process, thus affecting the machining accuracy and safety.

[0003] In addition, traditional grinding tools often lack angle adjustment functions, making the processing process inflexible. In practical applications, the shape and size of the bearing outer ring groove may vary from product to product, and the angle of the grinding block needs to be adjusted according to the specific situation. However, traditional grinding tools often cannot meet this demand, resulting in low processing efficiency and even failure to meet product quality requirements. For this reason, we provide a grinding tool for bearing outer ring groove processing. Utility Model Content
