Place the welding box 11 on the support assembly 2, so that one side of the box is in contact with the limiting block 8 to complete the initial positioning. Then, start the cylinder support 18 to drive the vertical beam pressure plate 17 to move the top block 9 towards the box until the top block 9 is in close contact with the other side of the box to achieve side clamping and fixation. At the same time, start the second electric push rod 14 to drive the push block 13 to move the top plate 12 towards the end of the box, so that the top plate 12 is in contact with the end of the box to complete the end fixation.

After completing the above fixation and positioning, start the welding assembly 6 to perform FSW welding on the welding box 11 according to the preset welding path. After welding is completed, release each clamping and holding component in sequence and take out the welded box.
