At the same time, the limiting processing mechanism 14 at the front end also operates synchronously to align the center of the second metal sheet 39, and then the horizontal hydraulic seat 32 works, and the horizontal hydraulic seat 32 The telescopic guide rod 33 is driven to extend, thereby squeezing the first metal sheet 38 and the second metal sheet 39, so that the first metal sheet 38 and the second metal sheet 39 are aligned, and then the first electric hydraulic control rod 6 is controlled to descend, the position of the connecting frame 5 and the matching seat 7 is changed, and the position of the laser welding head 8 is adjusted at the same time. The laser welding machine 11 is electrically connected to the laser welding head 8 through the connecting harness 9, and the screw rod can control the laser welding head 8 to slide on the limiting guide rod 10. At this time, the laser welding head 8 performs welding at the center position of the first metal sheet 38 and the second metal sheet 39. After the welding is completed, wait for cooling. Afterwards, the first screw rod 17 rotates on the frame 16 to change the position of the displacement adjustment seat 20 on the frame 16.
