One end of the bidirectional lead screw 6 is rotatably connected to the bracket 4, and a pair of connecting blocks 7 are threaded onto the bidirectional lead screw 6. A limit rod 8 is fixedly connected to the bracket 4. The limit rod 8 passes through the two connecting blocks 7 and can effectively limit the movement of the two connecting blocks 7. A laser spot welding machine 9 is installed at the lower end of the connecting blocks 7. The lower end is provided with a welding head 10, and a horizontal plate 11 is fixedly connected to one side of the connecting block 7. A suction head 12 is provided on the horizontal plate 11, and the suction head 12 cooperates with the suction assembly.

Simultaneously, the two bolts 23 are rotated, causing the two bolts 23 to move the two clamping plates 24 respectively, clamping and fixing the bent steamer plate. Then, the motor 5 is started, driving the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 can move the two connecting blocks 7, and the connecting blocks 7 can move more stably under the limiting action of the limiting rod 8. This allows for adjustment of the distance between the two welding heads 10, facilitating simultaneous two-point welding of the bent steamer plate. This device mainly targets symmetrical welding points on the bent steamer plate. Simultaneously, the laser spot welding machine 9 and the electric telescopic rod 3 are started, allowing the electric telescopic rod 3 to... The welding head 10 is moved downwards to weld the bent steamer plate. At the same time, the fan 13 is started. Under the action of the fan 13, the suction head 12 can absorb the fumes generated during the welding process and enter the fume treatment box 15 through the telescopic hose 17. The fumes are then purified through the activated carbon filter layer 16. This device can avoid the need for manual welding with a welding gun, thus improving processing efficiency and preventing the fumes from harming the human body.
