When the second worm 7 rotates, it can drive the second worm gear 6 to rotate, thereby rotating the driving disk 8. At the same time, the transmission system of the two has self-locking properties, and the second worm 7 stops rotating. After that, the second worm gear 6 is locked, and the outer wall of the driving disk 8 is provided with a plurality of grooves 8a at equal intervals along the circumferential direction, and the radius of the groove 8a is smaller than the radius of the driving disk 8. The outer walls of the driving disk 8 and the groove 8a are in contact with the clamping arm 10 respectively, which can drive the clamping arm 10 to embrace or expand inward. One end of the spring 12 is installed on the outer wall of the clamping arm 10, and the other end of the spring 12 is installed on the inner wall of the mounting base 5. When the driving disk 8 rotates, the groove 8a corresponds to the clamping arm 10, and the elastic force of the spring 12 is used to drive the clamping arm 10 to expand.

[0019] As a preferred solution, further, a placement table 11 is installed at the center position of the top of the mounting base 5, and a buffer cavity 14 is opened at the center position of the placement table 11. The bottom end of the buffer cavity 14 does not contact the workpiece, and the punching tool is buffered in this space after penetrating the outer wall of the workpiece, while ensuring that the hole is penetrated to avoid damage to the outer wall of the equipment.

[0020] As a preferred solution, further, the inner cavity of the base 1 is rotatably installed with a first worm gear 2, and the top of the first worm gear 2 is fixedly connected to the bottom end of the mounting base 5, and the inner wall of the base 1 is rotatably installed with one end of the first worm 3, and the first worm 3 and the first worm gear 2 are engaged with each other.

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0022] When in use, the metal disk workpiece to be processed is placed on the top of the placement table 11, the equipment is installed on the machine tool, and the punching position of the workpiece is made to correspond to the machine head, and then the second worm 7 is rotated to make the second worm gear 6 rotate, thereby making the drive disk 8 rotate. When the part in contact with the clamping arm 10 is converted from the groove 8a to the outer wall of the drive disk 8, the clamping arm 10 will rotate, thereby driving each clamping arm 10 to clamp the workpiece and position the workpiece circumferentially and longitudinally. Then, holes can be punched, and the motor 4 is turned on to drive the first worm 3 to rotate, thereby driving the first worm gear 2 to drive the mounting base 5 to rotate, so that the workpiece rotates together, thereby changing the relative position between the punching position and the machine tool head, and ensuring that the relative position is always on the circumference of the required punching position, thereby realizing circumferential punching. In actual use, it can not only achieve stable positioning of the metal disk workpiece, but also provide circumferential and longitudinal directions to avoid displacement of the punching, and can also quickly switch the punching position. The equipment has high stability and is easy to operate.
