The connecting cover 607 is fixedly connected to the clamping block 604. The rotating head 608 is movably installed in the connecting cover 607. One end of the adjusting screw 609 passes through the connecting cover 607 and is fixedly connected to the rotating head 608. The operating panel 610 is fixedly connected to the other end of the adjusting screw 609. Both ends of the double-headed screw 3 are movably installed with the mounting frame 1 through the rotating shaft 4. A stepping motor 5 is fixedly connected to one side of the mounting frame 1. The output of the stepping motor 5 The output shaft is fixedly connected to one end of the double-headed screw 3, and the clamping assembly 6 also includes a limiting block 603, a rubber pad 605 and a limiting groove 606. The limiting block 603 is fixedly connected in the ferrule 602, and the limiting groove 606 is arranged on the clamping block 604. The limiting block 603 and the limiting groove 606 are movably installed, and the rubber pad 605 is fixedly connected to the outer end position of the clamping block 604. The upper and lower surfaces of the clamping block 604 are slidably connected with the top and bottom of the ferrule 602, so that the clamping block 604 will not rotate in the ferrule 602 and keep moving in a straight line. When the adjusting screw 609 is turned When moving, the rotating head 608 at one end of the adjusting screw 609 rotates synchronously with the connecting cover 607, and the rotating head 608 pushes the clamping block 604 or pulls the connecting cover 607 and the clamping block 604 to move in the opposite direction, so that the clamping block 604 can move freely in the sleeve 602, thereby adjusting the position of the clamping block 604, making the position of the clamping block 604 easy to adjust, and by adjusting the position of the clamping block 604 in turn, multiple clamping blocks 604 can fit the surface of the special-shaped workpiece, so that the clamping assembly 6 is easy to fix a variety of different types of workpieces, thereby improving the applicability of the clamping assembly 6.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the slide bar 612 is movably installed with the ferrule 602 and is located at both sides of the adjusting screw 609. One end of the slide bar 612 is fixedly connected with a slide plate 615, and the positioning rod 616 is fixedly connected with the slide plate 615. The clamping assembly 6 also includes a positioning hole 611, which is provided on the operating plate 610. The positioning rod 616 is movably installed in the positioning hole 611.

When the adjusting screw 609 is rotated, the slide plate 615 is pushed sideways so that the positioning rod 616 moves out of the positioning hole 611 of the operating plate 610. When the adjusting screw 609 is adjusted to a suitable position, the slide plate 615 is released so that the spring 614 pushes the slide plate 615 to move in the opposite direction, so that the positioning rod 616 of the slide plate 615 is inserted into the corresponding positioning hole 611, thereby limiting the operating plate 610 and the adjusting screw 609, so that the fixing effect of the clamping block 604 is better and less susceptible to vibration.

[0023] It should be noted that the utility model is a clamp that can fix various types of workpieces. The slide plate 615 is pushed sideways so that the slide bar 612 moves inward in the slide hole 613, the spring 614 on the slide bar 612 is compressed, and the positioning rod 616 on the side of the slide plate 615 is moved out of the operating plate 610, thereby releasing the fixed limit of the operating plate 610, and then the operating plate 610 is rotated so that the adjusting screw 609 rotates in the screw hole of the ferrule 602, and the rotating head 608 rotates in the connecting cover 607. The rotating head 608 pushes the clamping block 604 to move outward, or the rotating head 608 pulls the connecting cover 607 and the clamping block 604 to move inward, so that the position of the clamping block 604 is adjusted. By adjusting the position of the clamping block 604 in turn, the respective clamping blocks 604 in the ferrules 602 on both sides fit the surface of the special-shaped workpiece, so that the clamping The fixing effect is better, and various types of workpieces can be fixed to improve applicability. When the clamping block 604 is adjusted to a suitable position, the slide plate 615 is released to allow the compressed spring 614 to resume expansion, and the slide plate 615 and the positioning rod 616 are pushed to move in the opposite direction, so that the positioning rod 616 is inserted into the corresponding positioning hole 611 on the operating plate 610, thereby limiting the rotation of the operating plate 610 and the adjusting screw 609, so that the fixing effect of the adjusting screw 609 is better, and it is more fixed and not easy to loosen when facing vibration. The workpiece is placed between the ferrules 602, and the stepper motor 5 is started to rotate the double-headed screw 3. Threads are engraved on both ends of the double-headed screw 3, and the slider 601 moves toward each other through the screw hole, so that the two ferrules 602 approach each other, and each clamping block 604 in the ferrule 602 squeezes and fixes the workpiece through the rubber pad 605.
