To move the welding head 54, the moving assembly adopts the existing front, back, left and right moving assembly, which is similar to the moving assembly on a CNC machine tool.

[0041] A shielding assembly 6 is also provided on the upper surface of the base 1 to shield the welding part. The shielding assembly 6 includes a baffle 61 and a shielding motor 62. The baffle 61 shields the welding, and the shielding motor 62 moves the baffle 61. The lower surface of the baffle 61 is fixedly connected with a rack 63 for convenient connection with a gear 65.

The gear 65 is meshed with the rack 63 to facilitate driving the rack 63 to move. The shielding motor 62 is fixedly connected to the base 1.

[0042] Working principle: Before use, two workers stand on both sides of the base 1, and the welding assembly 5 in the middle can be selected as many as needed, and the positions of the clamping assemblies on the two transmission devices 2 are adjusted to a mode in which one is welding and the other is transmitting;

[0043] When in use, the staff will fit the welding position of the seat chassis that needs to be welded with the cooling pipe 3433, insert it under the pressure plate 352, and the first pressure sensor 353 will sense it and control the second electric telescopic rod 3421 to push the pressure rod 3422, so that the other end of the seat chassis is engaged with the clamping plate 3423, and then control the first electric telescopic rod 3411 to lower the clamping plate 3412 to press the welded parts, thereby determining the welding position.

[0044] To perform welding, when the conveyor belt 22 transfers the clamping assembly 3 to the welding position, the front clamping assembly 35 contacts the positioning rod 43, and the second pressure sensor 44 detects the pressure, causing the conveyor belt 22 to stop transmitting. At the same time, the rotating motor 42 causes the positioning rod 43 to rotate and rise, and welding is performed through the welding head 54.

[0045] After welding is completed, the conveyor belt 22 moves. When it is transported to the unloading position, the front end clamping assembly 35 connected to the mounting seat 31 tilts upward due to the conveying roller 21. The first pressure sensor 353 cannot detect the pressure, so that the side pressing device 341 opens, allowing the next welding component to enter the welding position, and the staff can directly take out the welded seat chassis.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
