Description

Technical Field

[0001] The utility model relates to the technical field of mechanical clamps, and more specifically, to a precision machining mechanical clamp. Background Art

[0002] In the machining of mechanical workpieces, fixtures are indispensable. Fixtures are used to fix the workpieces, making them convenient for subsequent cutting, grinding and other processing operations. However, due to the different sizes and shapes of workpieces, in actual operations, in order to improve the fixing effect, it is often necessary to replace different fixture heads according to different workpiece requirements. However, traditional partial fixtures use small parts such as bolts and nuts to fix the fixture head. This design requires the removal of all these fixing parts when replacing the fixture head, and then re-screwing and fixing them after the replacement is completed, resulting in cumbersome and time-consuming operations. Frequent disassembly may damage the threaded holes and affect the fixing effect of the fixture head. Utility Model Content
