Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a mechanical processing fixture with a clamping mechanism for precision mechanical processing. Background Art
[0002] Precision machining is a process of using machining machinery to change the shape, size or performance of a workpiece. It is divided into cold machining and hot machining according to the temperature state of the workpiece being machined. Generally, machining at room temperature and does not cause chemical or physical changes in the workpiece is called cold machining. Generally, machining at temperatures above or below room temperature will cause chemical or physical changes in the workpiece, which is called hot machining. During machining, parts need to be clamped to facilitate subsequent processing. However, the fixtures currently used generally cannot be disassembled and assembled separately. After damage, a single fixture cannot be clamped and installed. Often, a whole set of clamping components must be replaced, which invisibly increases economic expenditures. Utility Model Content
