[0002] A bumper mounting bracket is a structural component installed on an automobile bumper, used to support the bumper and firmly connect it to the vehicle body. These brackets are usually made of metal or plastic and have a certain strength and stiffness to ensure that they can withstand external impact forces during a collision. For metal bumper mounting brackets, welding is required during processing. To improve the welding quality, a jig needs to be set up for clamping. The existing jigs for welding bumper mounting brackets generally use two clamping components with adjustable spacing to splice two workpieces to be welded together and then perform welding. However, the shapes of bumper mounting brackets vary, and it may be necessary to splice two workpieces at a certain inclination angle before welding. Therefore, one workpiece needs to be held by hand and spliced to the other. For this reason, a jig for welding a bumper mounting bracket is designed, which has two sets of clamping mechanisms, the spacing and inclination angle between the two sets of clamping mechanisms can be adjusted, and one of the clamping mechanisms can be adjusted for self-rotation, facilitating horizontal and inclined splicing, and further ensuring the welding quality of the bumper mounting bracket.

Detailed implementation mode
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0019] Embodiment:
[0020] Please refer to Figures 1-3 , a fixture for welding a bumper mounting bracket, including a support frame 1. Two sets of clamping mechanisms are arranged on the upper side of the support frame 1 and are separately arranged on both sides. One set of clamping mechanisms is rotatably connected to the support frame 1, and the other set of clamping mechanisms can perform spacing adjustment and inclination adjustment around this set of clamping mechanisms. A spacing adjustment mechanism and an inclination adjustment mechanism for adjusting the other set of clamping mechanisms are arranged on the support frame 1.
[0021] Specifically, it further includes a rotation mechanism for driving one set of clamping mechanisms to rotate. The rotation mechanism includes a rotation adjustment motor 8 fixedly installed on the support frame 1. A gear 9 is fixedly installed on the output shaft of the rotation adjustment motor 8. A toothed ring 10 is fixedly installed on this set of clamping mechanisms, and the gear 9 meshes with the toothed ring 10. Start the rotation adjustment motor 8 to make the output shaft of the rotation adjustment motor 8 rotate clockwise or counterclockwise, thereby driving the gear 9 to rotate clockwise or counterclockwise and mesh with the toothed ring 10, and then driving this set of clamping mechanisms to rotate counterclockwise or clockwise, so as to facilitate the counterclockwise or clockwise self-rotation of the main workpiece.
[0022] Specifically, one side of the clamping mechanism is rotatably connected to a rotating support bar 2 through a rotating shaft, and a spacing adjustment slider 4 is slidably fitted on the rotating support bar 2. Another group of clamping mechanisms is fixedly connected to the spacing adjustment slider 4. The spacing adjustment mechanism includes a screw 3 rotatably connected to the rotating support bar 2, and the spacing adjustment slider 4 is rotatably connected to the screw 3. The inclination adjustment mechanism includes an inclination adjustment motor 6 fixedly mounted on the support frame 1, and the output shaft of the inclination adjustment motor 6 is connected to the rotating shaft through a transmission assembly 7. Furthermore, a driving button 5 for driving the screw 3 to rotate is provided on one side of the screw 3 close to the clamping mechanism, which can be The driving button 5 drives the screw 3 to rotate clockwise or counterclockwise and engages with the spacing adjustment slider 4, thereby driving the spacing adjustment slider 4 to move closer to or away from one side of the clamping mechanism, thereby adjusting the distance between the two clamping mechanisms. By starting the inclination adjustment motor 6, the output shaft of the inclination adjustment motor 6 rotates clockwise or counterclockwise, and through the transmission cooperation of the transmission component 7, it is convenient to drive the rotating support bar 2 to rotate clockwise or counterclockwise, thereby driving the other group of clamping mechanisms to adjust the tilt. Furthermore, the transmission component 7 can be set to a sprocket chain or pulley belt transmission form for transmission.
[0023] Specifically, the clamping mechanism includes two groups of symmetrically arranged clamping boxes 12, the two clamping boxes 12 are fixedly connected by a cylinder 11 covered on the outside, and a plurality of clamping magnetic columns 13 are slidably matched on opposite sides of the two clamping boxes 12, and the clamping magnetic columns 13 arranged on the two groups of clamping boxes 12 magnetically repel each other, and an electromagnetic plate 14 is fixedly installed on the clamping box 12 to magnetically repel the plurality of clamping magnetic columns 13. The cylinder 11 is used to facilitate fixing the two relatively arranged clamping boxes 12, and the electromagnetic plate 14 can be turned off to open the clamping box 12. The clamping magnetic columns 13 on the box 12 magnetically repel each other, so that the multiple clamping magnetic columns 13 on both sides can be separated by a certain distance, so as to facilitate the placement of the workpiece between the two sides, and then the electromagnetic plate 14 is energized to overcome the magnetic repulsion of the clamping magnetic columns 13 on both sides and push the multiple clamping magnetic columns 13 outward to clamp the workpiece. This structure is convenient for clamping workpieces of various irregular shapes, and has relatively small clamping limitations. Furthermore, the clamping box 12 and the cylinder 11 are fixedly connected by two sets of connecting blocks 15.
[0024] Specifically, one side of the support frame 1 further includes two groups of support rings, and the cylinder 11 in the clamping mechanism is rotatably connected to the two groups of support rings. The two groups of support rings facilitate rotational support of the clamping mechanism.
[0025] In use, the main workpiece is clamped on the clamping mechanism rotatably connected to the support frame 1, and then two sub-workpieces are clamped on another set of clamping mechanisms. Then, according to the position of the splicing surface of the two, the sub-workpiece is first tilted and rotated by the inclination adjustment mechanism, and then moved toward the main workpiece side by the spacing adjustment mechanism. At the same time, the clamping mechanism rotatably connected to the support frame 1 is rotated, so that the main workpiece is rotated to a certain angle, so that the splicing surface of the sub-workpiece is aligned and fitted with the main workpiece, thereby facilitating welding.
