Full-automatic numerical control machine tool for air cylinder machining

The invention discloses a full-automatic numerical control machine tool for air cylinder machining. The device comprises a rack, the inner wall of the rack is rotationally connected with a revolution table driven by a rotating motor, a distance adjusting module is installed on the surface of the revolution table, the circumferential side face of the distance adjusting module is in transmission connection with two symmetrically-arranged transmission clamping bases, and a set of clamping modules distributed in a circumferential array mode are installed between the opposite surfaces of the two transmission clamping bases; a support is fixedly installed on the back face of the rack, the inner wall of the support is rotationally connected with a corner rotating frame driven by a corner motor, and a lead screw transmission module is installed in the corner rotating frame. A single-drilling tool bit structure of a traditional numerical control device is changed into a multi-drilling tool bit structure, and in the nu
