Before use, adjust the position of the front connecting block 10 according to the size of the plate to be welded, and then horizontally clamp the plate with the two clamping members 11. Drive the U-shaped lifting plate 7 to lift through the lifting screw rod 122 in the driving unit 12, so as to adjust the height of the horizontal plate above the vertical plate, and flexibly adapt to the positioning work of plates of different sizes. Drive the vertical plate to move below the horizontal plate through the moving plate 4, and use the pushing plate 134 in the fixing unit 13 to clamp and fix the vertical plate. The two plates are perpendicular to each other, which is convenient for subsequent welding work and improves the efficiency of chassis welding.
[0022] Furthermore, as Figure 2 - Figure 4As shown in the figure, the clamping member 11 includes a mounting block 111. The mounting block 111 is fixedly connected to the right end of the connecting block 10. A fastening bolt 112 is threadedly connected to the top of the mounting block 111. The bottom of the fastening bolt 112 is fixedly connected to a pressing block 113. The fixing unit 13 includes a second driving motor 131. The second driving motor 131 is fixedly installed on the left side wall of the vertical plate 5.
