[0024] When the two battery box bottom plates 4 are placed on the conveyor 3 and moved to the bottom of the welding device 13, the servo cylinder in the cylinder groove is started to make its telescopic end push the welding device 13 to perform multiple spot welding on the joints of the two battery box bottom plates 4. When it is necessary to adjust the welding points of the two limit frame plates 14, the No. 1 motor 5 can be started to make its output end drive the No. 1 threaded rod 7 to rotate, so that the welding frame 8 moves longitudinally in the No. 1 groove 6 and then drives the welding device 13 to move longitudinally on the welding platform 1. When it is necessary to move the welding device 13 horizontally, it is only necessary to start the No. 2 motor 9 so that its output end drives the No. 2 threaded rod 11 to rotate, so that the moving block 12 moves horizontally in the No. 2 groove 10 and then drives the welding device 13 to move horizontally on the welding platform 1. There is no need to manually move the welding points of the two battery box bottom plates 4 to the bottom of the welding device 13 to achieve automatic spot welding, which saves time and effort and is more practical.

When it is necessary to adjust the welding points of the two limit frame plates 14, the No. 1 motor 5 can be started so that its output end drives the No. 1 threaded rod 7 to rotate, so that the welding frame 8 moves longitudinally in the No. 1 groove 6 and then drives the welding device 13 to move longitudinally on the welding platform 1. When it is necessary to move the welding device 13 horizontally, it is only necessary to start the No. 2 motor 9 so that its output end drives the No. 2 threaded rod 11 to rotate, so that the moving block 12 moves horizontally in the No. 2 groove 10 and then drives the welding device 13 to move horizontally on the welding platform 1. Automatic spot welding can be achieved without manually moving the welding points of the two battery box bottom plates 4 to the bottom of the welding device 13, which saves time and effort and is more practical.
