[0002] Auto parts are the various units that make up the entire car and the products that serve the car.

[0003] When producing automobile parts, it is necessary to use a milling cutter to grind the parts. Since the milling cutter rotates very fast during grinding, the parts are usually fixed with a clamp. However, when general clamps are used to fix parts with cylindrical outer surfaces, since the surface of the parts is curved, when the clamp clamps the parts, there will be a gap between the clamp and the parts, which may cause the parts to shake during grinding, affecting the processing quality. Therefore, we propose a clamp for processing automobile parts to solve the above-mentioned problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2 , Figure 3The utility model provides an embodiment: a fixture for processing automobile parts, comprising a workbench 1 for processing automobile parts, the top of the workbench 1 is fixedly connected with a support member 6 for supporting a cylindrical rod 17, the top of the support member 6 is fixedly connected with a cylindrical rod 17 for supporting a circular ring 16, the top of the cylindrical rod 17 is fixedly connected with a circular ring 16 for rotating a rotating shaft 4, the inner wall of the circular ring 16 is rotatably connected with the rotating shaft 4, the left side of the rotating shaft 4 is fixedly connected with a threaded rod 13 for rotating a stabilizing ring 12, the outer wall of the threaded rod 13 is threadedly connected with a stabilizing ring 12, so that the stabilizing ring 12 can rotate left and right on the outer wall of the threaded rod 13, the outer wall of the stabilizing ring 12 is provided with a limiting groove 14 for allowing a transmission rod 11 to slide, the outer wall of the stabilizing ring 12 is slidably connected with a hinge 21 connected to the transmission rod 11, and the top of the hinge 21 is hinged with a transmission The movable rod 11 and the right side of the transmission rod 11 slide in the limiting groove 14, so that the transmission rod 11 can slide in the limiting groove 14, which is convenient for adapting to the size of the workpiece to be processed. The left side of the threaded rod 13 is fixedly connected with a cylinder 10 supporting the transmission disc 7, and the left side of the cylinder 10 is fixedly connected with the transmission disc 7. The left side of the transmission rod 11 is hinged with a resistance member 3 connected to the transmission rod 11. The inner wall of the transmission disc 7 is provided with a limiting hole 8 for allowing the resistance member 3 to slide, which can limit the sliding range of the resistance member 3. The resistance member 3 penetrates and slides on the inner wall of the transmission disc 7, and the size of the resistance member 3 can be scaled. Two groups of support members 6 are provided, and the other group of support members 6 is provided on the left side of the first group of support members 6. The two groups of support members 6 can clamp the left and right ends of the workpiece to be processed more firmly to prevent the workpiece from moving during processing, thereby improving work efficiency.

[0033] Reference Figure 1 , Figure 5 , Figure 6 The bottom end of another group of support members 6 is fixedly connected with a ball 19 that can slide left and right in the second limiting groove 20. The right side of the ball 19 is fixedly connected with a spring 18. The inner wall of the workbench 1 is provided with a second limiting groove 20 for allowing the ball 19 to slide left and right. The right side of the spring 18 is fixedly connected to the right side of the second limiting groove 20. The ball 19 slides on the inner wall of the second limiting groove 20. The second limiting groove 20 is set to a trapezoidal shape, so that the ball 19 is not easy to fall out when sliding in the second limiting groove 20. When the workpiece is long, one end of the workpiece is placed in the resistance piece 3 on one side, and the ball 19 will slide to the left due to the pulling force of the spring 18, thereby lengthening the distance between the two groups of resistance pieces 3, and then the other end of the workpiece is placed in the resistance piece 3 on the other side. After the staff puts the workpiece into the two groups of resistance pieces 3, it will be subjected to the reverse force of the spring 18, so that the two groups of resistance pieces 3 clamp the workpiece, making it difficult for the workpiece to fall off during processing, thereby improving the processing quality.

[0034] Reference Figure 1 , Figure 4The inner wall of the ring 16 is fixedly connected with a rubber pad 15 connected with a bolt 9, and the top of the rubber pad 15 is rotatably connected with a bolt 9 supporting the rubber pad 15. During processing, the bolt 9 can be rotated to squeeze the rubber pad 15 to stabilize the rotating shaft 4 from rotating. The bolt 9 passes through and is rotatably connected to the top of the ring 16. The inside of the ring 16 is set to be hollow. The rotating shaft 4 passes through the ring 16, and the angle of the workpiece can be adjusted to adapt to various processing angles, thereby improving work efficiency. The right side of the rotating shaft 4 is fixedly connected with a rotating rod 5 that can drive the rotating shaft 4 to rotate.

[0035] Reference Figure 1 The bottom end of the workbench 1 is fixedly connected with table legs 2 for supporting the workbench 1 for processing automobile parts. There are four groups of table legs 2 and they are evenly distributed at the bottom end of the workbench 1. The evenly distributed table legs 2 can stabilize the workbench 1, make it stable when processing the workpiece, and not easy to shake, thereby improving the processing quality.

[0036] Working principle: When in use, first put one end of the workpiece into the left side resistance piece 3, rotate the stabilizing ring 12, the stabilizing ring 12 rotates left and right on the threaded rod 13, the hinge 21 slides in the limiting groove 14, and the hinge 21 drives the transmission rod 11 to slide when sliding, which can ensure that the four groups of transmission rods 11 will not rotate with the rotation of the stabilizing ring 12, and the left side of the transmission rod 11 drives the resistance piece 3 through the limiting hole 8, and the resistance piece 3 can only move in the limiting hole 8, so that the resistance piece 3 can scale and clamp the workpiece, and after successfully putting one end of the workpiece into the resistance piece 3, the workpiece is pushed to the left in the resistance piece 3, and the support piece 6 will drive the ball 19 to move to the left, and the ball 19 will be affected by the spring The pulling force of 18 moves to the left in the limit groove 20. After roughly determining whether the workpiece can be placed in the two groups of resistance members 3, the other end of the workpiece is placed in the right resistance member 3. After placement, the ball 19 will move to the right under the reverse force of the spring 18, so that the two groups of resistance members 3 clamp the workpiece. Rotating the rotating rod 5 can drive the rotating shaft 4 to rotate in the ring 16, so that the angle of the workpiece can be adjusted. After adjusting the appropriate angle, turn the bolt 9 downward to make the bolt 9 contact the rubber pad 15. The rubber pad 15 contacts the rotating shaft 4 through the ring 16, which can stabilize the rotating shaft 4 so that the rotating shaft 4 will not rotate during processing, thereby stabilizing the workpiece. After the operation is completed, the workpiece can be processed.
