Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, and more specifically, to a rotating part grinding processing device. Background Art

[0002] The so-called rotating parts are parts of various shapes made from raw materials with a cylindrical shape after mechanical processing. Their shapes are generally symmetrical about the center line of the cylinder, so they are called rotating parts. They usually appear as parts of rotating motion. Common transmission shafts, main shafts, motors and turbine rotors in life can all be called rotating parts.

[0003] When operators are processing rotating parts, they often use grinding equipment to improve the surface accuracy of the rotating parts, thereby reducing the friction that may be generated when the rotating parts rotate. In actual use, although the existing grinding equipment has basic grinding functions, the existing grinding equipment generally fixes the rotating parts by manually tightening the clamping chuck. This clamping method is time-consuming and labor-intensive, thereby reducing the processing efficiency of the rotating parts, and therefore needs to be improved. Utility Model Content
