[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The downward moving slide can drive the bearing seat to move downward. When the positioning seat at the outermost edge of the bearing seat is pressed against the highest cross frame, the bearing seat will continue to move downward. At this time, the clamping spring on the positioning seat at the outermost edge is deformed to offset the downward force of the bearing seat, so that the positioning seat close to the outermost edge of the bearing seat can be pressed against the cross frame at the second height, and so on, so that multiple positioning seats on the bearing seat can be pressed against multiple cross frames respectively, that is, the heights of multiple welding guns on multiple positioning seats can be lowered in turn to adapt to the heights of the multiple cross frames, so as to achieve the purpose of welding multiple cross frames and arc frames together at the same time, thereby shortening the welding time and improving the welding efficiency.

[0013] 2.

At the same time, under the action of multiple support seats arranged in a linear array and in a stepped manner, multiple cross frames can be placed in the limiting grooves on the multiple support seats in turn, so that under the support limit of the support seat, the multiple cross frames can be evenly distributed and aligned between the two arc frames to complete the positioning. The process does not require workers to additionally measure and position each cross frame, thereby effectively reducing the labor intensity of workers, saving time spent on measurement and positioning, and further improving welding efficiency.

[0014] 3. When the bearing seat drives the welding gun downward, it will also drive the push plate to move downward synchronously. At this time, the push wheel rolls on the inclined surface of the push plate to drive the connecting frame to move backward. At this time, the guide frame slides on the clamping plate seat to assist the movement of the connecting frame, and then drives the arc frame on the second clamping plate to move backward to press against the arc frame, so that multiple cross frames can be tightly clamped between the two arc frames waiting for welding, so as to avoid the gap between the arc frame and the cross frame being too large, resulting in the phenomenon of not being welded together, so as to ensure the welding quality, and under the magnetic effect of the No. 3 magnetic block, the No. 2 magnetic block and the No. 1 magnetic block, the arc frame and the cross frame can be firmly adsorbed to avoid the arc frame or the cross frame falling off during the moving and clamping process, so as to ensure the positioning force of the arc frame and the cross frame.
