The driving component 31 is mounted on the base 10 and is used to drive the rack 33 to move, so as to drive the gear 32 to rotate, thereby rotating the rotating shaft 40.

[0068] In this way, the driving component 31 drives the rack 33 to move, drives the gear 32 to rotate, thereby drives the rotating shaft 40 to rotate, and then drives the mounting frame 21 to rotate, so as to adjust the angle of the parts clamped by the clamping member 22 on the mounting frame 21.

[0069] Specifically, the driving assembly 30 can be a combination of components for transmitting driving force. The driving assembly 30 can transmit the driving force from the power device to the rotating shaft 40 to drive the mounting frame 21 to rotate. The power device includes but is not limited to a motor, a cylinder, a hydraulic cylinder, etc.

[0070] The gear 32 can be integrally formed with the rotating shaft 40, or can be connected by welding. The number of teeth of the gear 32 can be the same as or different from the number of teeth of the rack 33. By designing the number of teeth on the gear 32 and the rack 33, the maximum rotation angle of the rotating shaft 40 can be set. When the number of teeth of the gear 32 is the same as the number of teeth of the rack 33, the maximum rotation angle of the rotating shaft 40 is 360°; when the number of teeth of the rack 33 is 1 / 2 of the number of teeth of the gear 32, the maximum rotation angle of the rotating shaft 40 is 180°; when the number of teeth of the rack 33 is 1 / 4 of the number of teeth of the gear 32, the maximum rotation angle of the rotating shaft 40 is 90°.

[0071] See also Figure 4 In some embodiments, the driving component 31 includes a third screw rod 34 and a slider 35 sleeved on the third screw rod 34 , and the rack 33 is fixedly connected to the slider 35 .

[0072] In this way, the slider 35 is sleeved on the third screw rod 34 , so that the rotation of the third screw rod 34 can drive the slider 35 to move, thereby driving the rack 33 to move.

[0073] Specifically, the length direction of the rack 33 can be consistent with the axial direction of the third screw rod 34, and the third screw rod 34 can be driven by a motor, by air pressure, or by hydraulic pressure. A groove 11 can be provided on the upper surface of the base 10, and the third screw rod 34 is located in the groove 11, and the slider 35 is clamped in two adjacent threaded surfaces of the third screw rod 34. The smaller the distance between the two adjacent threaded surfaces, the smaller the moving distance of the third screw rod 34 driving the rack 33 when it rotates one circle, the smaller the angle of rotation of the rotating shaft 40, and the higher the accuracy of the angle adjustment of the parts. The slider 35 and the rack 33 can be integrally formed or connected by welding. By setting the length of the third screw rod 34, the movement stroke of the slider 35 can be limited, the rotation angle of the gear 32 can be limited, and thus the rotation angle of the rotating shaft 40 can be limited.

[0074] In one embodiment, the working principle of the clamp 100 can be as follows: according to the model of the part, a suitable clamping member 22 is selected and installed on the clamp 100. After the clamping member 22 is installed, the second screw rod 243 is manually driven to rotate according to the height of the part to adjust the height of the clamping member 22. After the height is adjusted, the first screw rod 232 is manually driven to rotate so that the two fixed plates 24 are close to each other. The clamping members 22 on the two fixed plates 24 clamp the parts. After clamping, the third screw rod 34 is driven to rotate by the motor to adjust the angle of the part clamped by the clamping member 22 so that the part is in a suitable processing position.
