Description

Technical Field

[0001] The utility model relates to the field of machining, and particularly relates to a swing grinding device. Background Art

[0002] During the process of grinding and polishing mechanical parts by a grinding machine, when grinding the surface of a part that cannot rotate 360°, the existing grinding machine itself does not have a device for driving the swing of such a part. Therefore, when grinding such a part, it is generally necessary to use a manual auxiliary tool to control the swing of the part for grinding. However, after a long time of operation, the high-frequency manual swing of the part will cause the operator's hand to fatigue, resulting in the swing deviation, which affects the grinding of such a part. To solve this problem, a new type of swing grinding device is needed. Content of the Utility Model
