Machining clamp for numerical control machine tool

The utility model provides a machining fixture for a numerical control machine tool, relates to the technical field of machining fixtures for machine tools, and solves the problem that the working efficiency is reduced due to the fact that repeated clamping and tool setting are needed when a workpiece with a small size is subjected to rotary head machining in the actual application of the existing fixture for the numerical control machine tool. The main body of the clamping mechanism is designed into a disc-shaped structure, the auxiliary mechanism is arranged, the auxiliary assembly is designed into a split type structure, the impurity removing assembly is further arranged in the auxiliary assembly, the main body of the impurity removing assembly is the transmission shaft, and the impurity removing fan is further arranged on the outer side of the transmission shaft; and a brush in the cleaning assembly is further arranged on the right side of the impurity removal fan, so that impurities generated in the mach
