[0027] like Figures 1 to 5 As shown, a welding device for a torsion arm of an automotive seat connecting rod includes a base frame 1. A rotary motor 2 is fixedly installed on the bottom surface of the base frame 1. The output end of the rotary motor 2 passes through the base frame 1 and is fixedly connected to a base 3. A first threaded rod 31 is fixedly installed on the top surface of the base 3. A cover 4 is fitted over the top surface of the base 3 and the surface of the first threaded rod 31. A support adjustment component 5 is provided inside the cover 4. The position of the automotive seat connecting rod torsion arm support plate in the automotive seat connecting rod torsion arm frame is adjusted by the support adjustment component 5. A clamping nut 6 is threaded onto the surface of the first threaded rod 31 to fix the automotive seat connecting rod torsion arm support plate. An operating frame 7 is provided on the top surface of the base frame 1, and a handheld laser welding device 8 is fixedly installed on the mounting part of the operating frame 7. More specifically, the torsion arm support plate of the car seat connecting rod is placed on the top surface of the support adjustment assembly 5. The support adjustment assembly 5 then drives the torsion arm support plate of the car seat connecting rod to move vertically to a suitable processing position. The torsion arm support plate of the car seat connecting rod is fixed by tightening the nut 6 and threading the first threaded rod 31. The torsion arm frame of the car seat connecting rod is placed on the top surface of the cover 4, so that the torsion arm frame of the car seat connecting rod is located outside the torsion arm support plate of the car seat connecting rod. The operator uses a handheld laser welding device 8 for precise welding. After welding is completed, the handheld laser welding device 8 can be vertically retracted by the operating frame 7.

[0028] The support adjustment assembly 5 includes a second threaded rod 501 rotatably mounted on the top of the inner side of the cover 4, and a first bevel gear 502 fixedly sleeved on the surface of the second threaded rod 501. A rotating rod 503 is rotatably inserted into the surface of the cover 4, and a second bevel gear 504 is fixedly mounted at the end of the rotating rod 503. The second bevel gear 504 and the first bevel gear 502 mesh with each other. A movable plate 505 is threadedly sleeved on the surface of the second threaded rod 501, and a stepped support rod 506 and a support cover 507 are fixedly mounted on the top surface of the movable plate 505. The stepped support rod 506 and the support cover 507 are movably inserted into the top surface of the cover 4, and the support cover 507 is slidably sleeved on the surface of the first threaded rod 31. The stepped support rod 506 and the support cover 507 support the torsion arm support plate of the car seat connecting rod. More specifically, rotating the rotating rod 503 drives the second bevel gear 504 to rotate. The meshing of the second bevel gear 504 and the first bevel gear 502 drives the first bevel gear 502 and the second threaded rod 501 to rotate. The surfaces of the movable plate 505 and the second threaded rod 501 are threaded together, allowing the movable plate 505, the stepped support rod 506, and the support cover 507 to move vertically. This allows the distance between the torsion arm support plate of the car seat connecting rod and the top surface of the cover 4 to be adjusted via the stepped support rod 506 and the support cover 507, enabling the position of the torsion arm of the car seat connecting rod to be freely adjusted according to its size.

[0029] A guide rod 41 is fixedly installed on the bottom inner side of the cover 4, and the surfaces of the movable plate 505 and the guide rod 41 are slidably fitted together. More specifically, the guide rod 41 guides and limits the vertical movement of the movable plate 505.

[0030] The operating frame 7 includes a U-shaped frame 701 fixedly installed on the top surface of the base frame 1. Two sets of ropes 702 are fixedly installed on the inner top of the U-shaped frame 701, and mounting bases 704 are fixedly installed at the bottom ends of the ropes 702. Springs 703 are sleeved on the surface of the ropes 702, and the two ends of the springs 703 are fixedly connected to the opposite surfaces of the U-shaped frame 701 and the mounting bases 704, respectively. The handheld laser welding device 8 is fixedly inserted into the interior of the mounting bases 704. More specifically, when the handheld laser welding device 8 is idle, the elastic force of the ropes 702 and the springs 703 vertically lifts the handheld laser welding device 8. At this time, the ropes 702 are in a wavy and relaxed state. When using the handheld laser welding device 8, the operator holds the handheld laser welding device 8 and pulls it to move along the gap between the torsion arm frame of the car seat connecting rod and the torsion arm support plate of the car seat connecting rod to weld it. At this time, the springs 703 are stretched to ensure the flexibility and accuracy of the welding operation.

[0031] The top surface of the cover 4 has a stepped hole, and the top surfaces of the stepped support rod 506 and the support cover 507 can be flush with the inside of the stepped hole on the top surface of the cover 4. More specifically, the stepped support rod 506 and the support cover 507 can be stored through the stepped hole on the top surface of the cover 4.

[0032] A limiting ring is provided on the top surface of the base frame 1 to limit the rotation of the base 3 on the top surface of the base frame 1. More specifically, the limiting ring on the top surface of the base frame 1 is used to limit the planar movement of the base 3 when it rotates.

[0033] In summary: The torsion arm support plate of the car seat connecting rod is placed on the top surface of the support adjustment assembly 5. The support adjustment assembly 5 then drives the torsion arm support plate of the car seat connecting rod to move vertically to a suitable processing position. The torsion arm support plate of the car seat connecting rod is fixed by the threaded engagement of the clamping nut 6 with the surface thread of the first threaded rod 31. The torsion arm frame of the car seat connecting rod is placed on the top surface of the cover 4, so that the torsion arm frame of the car seat connecting rod is located outside the torsion arm support plate of the car seat connecting rod. The operator uses a handheld laser welding device 8 for precise welding. After welding is completed, the handheld laser welding device 8 can be vertically retracted via the operating frame 7.
