The simpler structure is welded by the bottom frame, top frame and vertical poles. The bottom frame and top frame are welded by four rectangular tubes. At present, when welding, the rectangular tubes are butt-jointed to form a rectangular structure, and then spot welding is performed first to fix the relative position between the rectangular tubes, and then full welding is performed. During the welding process, the frame structure needs to be constantly turned over to ensure the firmness after welding. When the weight of the frame structure is large, it will undoubtedly increase the difficulty of welding. Utility Model Content

After clamping, the position of the rectangular tube can be adjusted again by adjusting the screw 36, and finally the ends of each rectangular tube are tightly connected together. During the welding process, the back plate 3 can be rotated to facilitate welding operations at different positions.
