The two oppositely arranged clamping jaws 11 move toward the middle under the control of the driving device 5 to realize the clamping operation of the workpiece.

[0021] The base 16 can be connected to an operating table or a mechanical arm through a positioning hole 20. For the structure of the base 16 and the slide 13, see Figure 3 , its sliding setting method includes slotting a guide rail on the base 16, and the slide 13 slides along the guide rail. When in use, it can be manually adjusted to the target position and then locked. In some specific applications, it can be set to be automated, using a screw linear module 17, the screw linear module 17 includes a ball screw 18, a screw slider 19 is installed on the outer wall of the ball screw 18, and the screw slider 19 is assembled with the bottom of the slide 13; the end of the ball screw 18 is used to connect to the screw motor (not shown in the figure), and the screw motor and the ball screw 18 drive the screw slider 19 to move linearly; the position of the slide 13 is adjusted by the screw linear module 17, so that the clamping position can be changed before clamping, and after clamping the workpiece, the workpiece can be driven to achieve displacement, thereby improving flexibility.

[0022] Combination Figure 1 As shown, the base 16 is provided with a slidable slide 13, and a rotating table 14 is installed based on the opening of the slide 13. The rotating table 14 can be manually rotated by sleeve bearings in the through holes provided in the slide 13. When in use, it is locked by a rotating locking mechanism 15. The rotating locking mechanism 15 can be a combination of a bolt and a clamp, and the locking can be achieved by the bolt against the lower end of the slide 13. In some application modes, the rotating table 14 is set in an electric or pneumatic manner, including using a motor (stepping motor or servo motor) to drive the rotating table 14 to rotate through a driving shaft. More preferably, a telescopic mechanism 12 is set below the rotating table 14, and the telescopic mechanism 12 rotates together during the rotation process. The telescopic mechanism can be realized by an electric telescopic rod. Based on this structure, the clamping part below the utility model rotates, so that the mechanical clamp can have the effect of rotating to adjust the clamping position, and can conveniently adjust the clamping position during clamping, and adjust the angle of the workpiece by rotating after clamping the workpiece, so as to further improve the flexibility of the mechanical clamp.

[0023] Combination Figure 2 As shown, the lower part of the rotating table 14 is connected to the clamping assembly, and its two sides are symmetrically installed between the two clamp assembly frames 1. The clamping assembly 7 includes a bracket 8. The side wall of the bracket 8 can drive the motor 9. The driving motor 9 drives the slider 3 in the driving groove 2 to move. The slider 3 is located on the side of the clamp mounting part 7, including two. The clamp mounting part 7 can realize the installation of the clamp 11 through the connecting piece 10, and it is also possible to directly replace the clamp 11 later.

[0024] The driving mode of the driving motor 9 is a two-end drive, which is used to drive the clamping jaws to move closer to the middle of the clamp assembly frame along the slide groove to achieve workpiece clamping. The clamping movement of the clamping jaws 11 also includes being set in the middle drive, that is, the driving device is set in the middle of the clamp assembly frame.

[0026] A groove is provided on the side of the clamp assembly frame 1, and a rack or chain is arranged in the groove. The oppositely arranged clamp assembly frames 1 have a gear in the middle of the clamp assembly frame 1. The racks or chains in the clamp assembly frames 1 on both sides are meshed with the gears. The rotation of the gears can realize the movement of the two, one side to the right and the other side to the left, causing the clamping jaws 11 to move closer to or separate from the middle.
