[0023] In this embodiment, a clamping mechanism is provided on the clamping seat 1, and the clamping mechanism includes a servo motor 2, which is fixedly mounted on the side of the clamping seat 1. A bidirectional screw rod 3 is fixedly connected to the output shaft of the servo motor 2, and the bidirectional screw rod 3 is located inside the clamping seat 1. One end of the bidirectional screw rod 3 away from the servo motor 2 is connected to the inside of the clamping seat 1 through a bearing. Two transmission nuts 4 are threadedly connected to the outer side of the bidirectional screw rod 3, and connecting rods 5 are fixedly connected to the upper sides of the two transmission nuts 4. The opposite sides of the two connecting rods 5 are fixedly connected to mounting rods 6, and the opposite ends of the two mounting rods 6 are fixedly connected to movable plates 7.

[0024] Two fixing blocks 14 are fixedly mounted on the upper side of the clamping seat 1 , and a reset button 17 is also arranged on the outside of one of the fixing blocks 14 . The reset button 17 is used to control the operation of the servo motor 2 to restore the position of the driving nut 4 to its original position.

[0025] It should be noted that the two transmission nuts 4 are respectively located on two sections of threads on the bidirectional screw rod 3 that are arranged in opposite directions to each other.

[0026] It should be added that the bottom of the two transmission nuts 4 are fixedly connected with a slider 12, the inside of the clamping seat 1 is fixedly installed with a guide rail 13, and the two sliders 12 are slidably connected to the inner side of the guide rail 13. The cooperation between the slider 12 and the guide rail 13 can guide the transmission nuts 4, thereby improving the stability of the structure.

[0027] In this embodiment, a sensing component is also provided on the clamping seat 1, and the sensing component includes a first pressure sensor 8 and a second pressure sensor 11. The first pressure sensor 8 is fixedly connected to the upper side of the clamping seat 1, and the second pressure sensor 11 is fixedly connected to the outer side of one of the moving plates 7. The first pressure sensor 8 is used to sense the pressure and send a signal to the relevant controller so that it controls the servo motor 2 to automatically operate, and the second pressure sensor 11 is used to sense the pressure and send a signal to the relevant controller so that it controls the servo motor 2 to stop operating.

[0028] In this embodiment, an elastic component is provided on the outside of the second pressure sensor 11, and the elastic component includes a first spring 9 and a positioning plate 10. One end of the first spring 9 is fixedly connected to the movable plate 7 on which the second pressure sensor 11 is installed, and the other end of the first spring 9 is fixedly connected to the positioning plate 10. The second pressure sensor 11 is located between the movable plate 7 and the positioning plate 10.

[0029] It should be supplemented that the outer sides of the two fixed blocks 14 are fixedly connected with mounting covers 15, the two connecting rods 5 extend to the inner sides of the two mounting covers 15 respectively, a second spring 16 is sleeved on the outer wall of the mounting rod 6, one end of the second spring 16 abuts against the connecting rod 5, and the other end of the second spring 16 abuts against the inner wall of the mounting cover 15, and a strip opening for the connecting rod 5 to pass through is opened on the inner side of the clamping seat 1, and the number of the strip openings is two.

[0030] The working principle of the above embodiment is:

[0031] When the utility model is in use, the workpiece to be fixed is placed on the clamping seat 1, and the workpiece contacts the first pressure sensor 8 on the clamping seat 1. The first pressure sensor 8 is used to sense the pressure and send a signal to the relevant controller, so that it controls the servo motor 2 to automatically operate. The servo motor 2 will drive the bidirectional screw rod 3 to rotate, and drive the two transmission nuts 4 to approach each other, thereby driving the two moving plates 7 to approach each other, and then clamping the workpiece. While clamping the workpiece, the positioning plate 10 on the moving plate 7 equipped with the second pressure sensor 11 contacts the workpiece and squeezes the first spring 9, so that the second pressure sensor 11 is in close contact with the positioning plate 10. The second pressure sensor 11 is used to sense the pressure and send a signal to the relevant controller, so that it controls the servo motor 2 to stop running and complete the fixation. After the workpiece processing is completed, the reset button 17 is pressed to control the servo motor 2 to drive the bidirectional screw rod 3 to rotate in the opposite direction, thereby driving the two transmission nuts 4 to move away from each other, and restoring the two transmission nuts 4 to their original positions, so as to release the fixation of the workpiece.
