Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinder with adjustable processing diameter. Background Art

[0002] The retaining ring is a mechanical part, usually installed on the shaft, used to limit the position of the part in axial motion. It is widely used. In order to ensure the installation fit of the produced retaining ring, a grinder is needed to grind the retaining ring.

[0003] Most of the existing grinders do not have the function of adjusting the grinding diameter. Since the diameters of the produced retaining rings are different, when it is necessary to grind a retaining ring with a larger diameter, it is necessary to replace the grinding disc with an adapted diameter, which takes time to replace accessories and results in low work efficiency. In addition, the traditional grinder can only grind one side of the retaining ring at a time. After grinding one side of the retaining ring, it is necessary to manually disassemble the retaining ring and flip it over, and then fix the retaining ring before grinding it again. The operation steps are cumbersome and time-consuming, which easily affects the processing efficiency.

[0004] For this purpose, we propose a grinding machine with adjustable processing diameter. Utility Model Content

[0022] Each first threaded rod 14 is provided with two sections of threads facing each other, and the two sliders 15 are respectively sleeved on the two sections of threads. This design is conducive to the use of the present device. A second motor 8 is fixedly installed at the bottom end of the driving groove 17, and the output end of the second motor 8 is fixedly installed on the gear plate 9.
