[0048] Working principle:

[0049] In the initial state, the first cylinder 28 contracts to move the push plate 26 away from the abutment plate 25, and the second cylinder 42 contracts to lift the bottom end of the pressing member 43 upward. Figure 1 The protective frame body (hereinafter referred to as the frame body) shown has one long rod abutting against the push plate 26, another long rod placed close to the abutment plate 25, and two short rods respectively located in two sets of positioning plates 20 on the crossbeam 24;

[0050] First, start the first cylinder 28 to extend its movable end, push the push plate 26 to drive the frame to move along the positioning plate 20, until the two long rods of the frame abut against the abutment plate 25 and the push plate 26 at the same time, and the short rod abuts against the long rod, and the frame is assembled and clamped;

After welding, the first cylinder 28 and the second cylinder 42 are returned to their initial positions, and the finished frame can be removed.

[0053] The flipping process is as follows: step on the pedal rod 55 to rotate it downward, drive the clamping column 53 to compress the spring 57 through the connecting rod 56, so that the clamping column 53 moves down and completely disengages from the bottom slot 52, and the welding frame 2 is rotated 90° or 180° along the bearing 12 and the rotating rod 13. After the rotation, the other slot 52 is located at the bottom, and the pedal rod 55 is released. Under the action of the spring 57 to reset, the clamping column 53 moves up and is inserted into the slot 52 at the bottom, so as to limit the position of the welding frame 2 and perform welding on the other side.
