Description

Technical Field

[0001] The utility model belongs to the technical field of precision bearing processing, in particular to a groove grinder for precision bearing processing. Background Art

[0002] When machining bearings, grooves need to be cut on the outer and inner rings of the bearings by machine tools. The grooves are in direct contact with the bearing balls and have strict precision requirements. Therefore, grinders are generally used to machine the grooves.

[0003] During use, the existing groove grinders for precision bearing processing are restricted by precision bearings of different sizes. The grinding head needs to be disassembled and the position of the grinding head needs to be changed to facilitate grinding of grooves of different depths and positions. At the same time, the positioning ring for fixing the bearing needs to be disassembled and replaced, which cannot effectively fix bearings of different sizes, thereby wasting manpower and reducing efficiency.

[0004] For example (authorization announcement number CN220128408U) a groove grinder for precision bearing processing can drive the top shaft to move toward the top block through the slide seat, fix the inner ring of the bearing from the inside through the positioning ring on the top block and the top shaft, and then drive the grinding head down through the telescopic part to process the groove. This method is faster and simpler than the conventional fixing method, can effectively improve the processing efficiency of the grinder, and has good actual use effect. This device has this problem: it cannot fix precision bearings of different sizes during use, and cannot grind out grooves of different depths and positions, which reduces the use efficiency.
