[0037] The anti-deviation mechanism 5 includes a fixed threaded rod 51, a limit mounting pad 52 fixed to the top of the fixed threaded rod 51, a movable bracket 53 movably sleeved on the outside of the fixed threaded rod 51, two positioning nuts 54 threadedly connected to the outside of the fixed threaded rod 51, a guide groove 55 opened inside the movable bracket 53, a movable mounting rod 56 extending through its bottom movably inserted into the top of the movable bracket 53, a cast iron block 57 fixed to the top of the movable mounting rod 56, a positioning pad 58 fixed to the bottom of the movable mounting rod 56, a fixed mounting sleeve 510 movably sleeved on the outside of the movable mounting rod 56, multiple positioning connection holes 59 opened inside the movable bracket 53, a fixed threaded sleeve 511 fixed to the top of the fixed mounting sleeve 510, a positioning threaded rod 512 extending through its bottom threadedly connected to the top of the fixed threaded sleeve 511, and a positioning threaded rod 512 fixed to the top of the positioning threaded rod 512. A rubber sleeve 513 is provided. The size of the positioning threaded rod 512 is adapted to the size of the positioning connection hole 59. The size of the guide groove 55 is adapted to the size of the movable mounting rod 56, allowing the movable mounting rod 56 to move within the guide groove 55. At the same time, after one end of the positioning threaded rod 512 is movably inserted into the corresponding positioning connection hole 59, the position of the movable mounting rod 56 can be fixed. The fixed threaded rod 51 and the metal fixing block 3 are fixedly connected. The outer side of the positioning nut 54 is provided with anti-slip texture, which makes it easy for the user to rotate the positioning nut 54. The inside of the fixed mounting sleeve 510 is provided with a through hole, the size of which is adapted to the size of the positioning threaded rod 512. The spacing between adjacent positioning connection holes 59 is equal. The inside of the movable bracket 53 is provided with a through hole adapted to the size of the fixed threaded rod 51, allowing the movable bracket 53 to move vertically outside the fixed threaded rod 51.

[0038] The auxiliary positioning mechanism 6 includes a fixed bracket 61. A movable metal plate 62 is movably inserted into one side of the fixed bracket 61 and extends through the other side. A positioning connecting block 63 is fixed to one end of the movable metal plate 62, and a handle pad 64 is fixed to one end of the movable metal plate 62. A movable rod 65 extends through the bottom of the movable metal plate 62 and is movably inserted into the top of the movable metal plate 62. A plastic plate 66 is fixed to the top of the movable rod 65, and a positioning suction cup 67 is installed at the bottom of the movable rod 65, allowing the movable metal plate 62 to move horizontally along with the positioning connecting block 63. The fixed bracket 61 and the metal fixing seat 4 are fixedly connected. The fixed bracket 61 has a through groove inside to accommodate the movement of the movable metal plate 62, and the movable metal plate 62 has a through hole inside. The size of the through hole is adapted to the size of the movable rod 65, allowing the positioning suction cup 67 to move up and down along with the movable rod 65.

[0039] Working Principle: During the welding and positioning of automotive metal parts, the automotive metal parts are placed on the welding platform 1. Specifically, the automotive metal parts are positioned below the positioning pad 58. The movable bracket 53 can then be moved to the outside of the fixed threaded rod 51, allowing the bottom surface of the positioning pad 58 to align with the top of the automotive metal part. After height adjustment, the two positioning nuts 54 on the outside of the fixed threaded rod 51 can be rotated, causing the corresponding surfaces of the positioning nuts 54 to align with the outside of the movable bracket 53. This facilitates locking the movable bracket 53 after adjustment and simultaneously locks the height of the positioning pad 58. This allows for the positioning and reinforcement of the top of the automotive metal part using the positioning pad 58 without affecting normal welding, thus preventing displacement during the welding process. Furthermore, the forward and backward position of the movable mounting rod 56 can be adjusted according to the welding and positioning requirements of the automotive metal part. Adjustment can be achieved by moving the movable mounting rod 56. The mounting rod 56 moves within the guide groove 55. At the same time, the fixed mounting sleeve 510 on the outside of the movable mounting rod 56 moves. After moving to the corresponding position, the rubber sleeve 513 is rotated clockwise, allowing one end of the positioning threaded rod 512 to be inserted into the corresponding positioning connection hole 59 to lock the position of the movable mounting rod 56. When the automotive metal part is placed on the welding platform 1 for welding positioning, the handle pad 64 can be pushed horizontally to move the moving metal plate 62 and the positioning connecting block 63, so that one end of the positioning connecting block 63 is attached to the outside of the corresponding automotive metal part. At this time, the plastic plate 66 is pressed vertically, so that the plastic plate 66 moves the movable rod 65 and the positioning suction cup 67, allowing the positioning suction cup 67 to be attached to the welding platform 1 to fix the position of the positioning connecting block 63. The two positioning connecting blocks 63 are clamped and fixed to the outside of the automotive metal part. The positioning operation is simple and facilitates the welding of automotive metal parts.
