Servomotor is fixed on the casing through motor cabinet by connecting plate, the little timing belt pulley of transmission system is installed on the optical axis of servomotor, big timing belt pulley is loaded on the microcephaly rear end of main shaft, and synchronous belt is connected between little timing belt pulley, the big timing belt pulley;

The main shaft big end surface is connected with terminal pad, and cylinder is connected the little end surface of main shaft through ring flange, and pull bar passes spindle hole and connects cylinder, and the other end connects locking nut;

Be connected with axis pin base on the casing, the bearing pin of band handle is contained on the axis pin base.

The utility model by original hand feed, manually control the processing dimension scope and change the calibration of realizing work spindle by the servomotor anglec of rotation into, workpiece locking realizes by rotary cylinder, workpiece is carried out auto lock and calibration, not only significantly improved production efficiency, and product quality is greatly improved.

The utility model compared with prior art changes pneuma-lock into by manual locking, has reduced labour intensity, has improved operating efficiency; Workpiece rotation calibration is by original manually changing into by the rotational automatic calibration of servomotor, and the error of division is little, accurate positioning.
