Description

technical field [0001] The invention relates to a machining tool, in particular to a clamping device for clamping the inside of a workpiece. Background technique [0002] The fixture that fixes the workpiece by clamping the outside of the workpiece so that it occupies the correct position will often cause scratches on the surface of the workpiece and affect the processing quality of the workpiece. Therefore, for some workpieces that need to protect the smoothness of the outside, by clamping the inside of the workpiece Fix the workpiece. At present, the fixtures for clamping the inside of the workpiece often have the defects of complex structure, inconvenient operation, and unstable clamping, which affects the processing quality of the workpiece. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an internal clamping device with a simple structure and stable clamping of workpieces. [0004] In order to solv...
