(1) When the machine tool parts need to be grooved, the staff first places the machine tool parts that need to be grooved on the upper surface of the clamping base 1. After placing the machine tool parts, start the drive motor 301. The output shaft begins to rotate, driving the threaded rod 302 to start rotating. At this time, the threaded barrel 303 threadedly connected to the outside of the threaded rod 302 begins to move outside the threaded rod 302, and the threaded barrel 303 moves in a direction close to the longitudinal central axis of the clamping base 1 , the movement of the threaded barrel 303 drives the moving block to slide inside the slide rail 305, and at the same time, the positioning plate 304 on the upper surface of the threaded barrel 303 moves in a direction close to the longitudinal central axis of the clamping base 1.

(2) The movement of the positioning plate 304 drives the clamping plate 313 to move in a direction close to the longitudinal central axis of the clamping base 1. The rubber plates on the opposite sides of the two clamping plates 313 push the machine tool accessories to the center of the clamping base 1. , to achieve the purpose of centering the machine tool accessories, and then the machine tool accessories need to be clamped. At this time, the staff starts the electric push rod 307, and the electric push rod 307 drives the movable block 308 to move upward. Under the action of the hinge frame, the movable block 308 moves upward. The movement drives the first connecting rod 314 to move, and drives the movable plate 311 to move in a direction close to the longitudinal central axis of the clamping base 1. The movement of the movable plate 311 drives the first slider 310 to slide inside the first slide groove 309, and at the same time drives the expansion and contraction. The rod 312 and the clamping plate 313 move in a direction close to the longitudinal central axis of the clamping base 1. When the two clamping plates 313 have completely fixed the machine tool accessories, close the electric push rod 307 and start grooving the machine tool accessories. .
