[0002] Steel structure welding is a technique that connects metal components through high-temperature melting. It is widely used in a variety of fields, including construction, bridges, and shipbuilding. It not only improves the integrity and stability of the structure, but also enhances the component's load-bearing capacity. During the welding process, precise control of welding parameters such as current, voltage, and welding speed ensures weld quality and prevents defects such as cracks and holes. Post-weld heat treatment and non-destructive testing are also important steps in ensuring weld quality. With the development of technology, the application of automated and intelligent welding technologies has further improved welding efficiency and quality, providing strong support for the development of modern industry. However, existing steel structures require welding on all four sides. However, when rotating one side of the steel structure after welding, the steel structure is usually removed from the clamping assembly, then flipped over and re-inserted into the clamping assembly for welding. This frequent disassembly and re-clamping can cause unnecessary damage or deformation to the steel structure. Utility Model Content

A water pump 238 is sleeved on the outer surface of the water pipe 234, and a connecting plate 237 is fixedly installed on the outer surface of the water pump 238. One end of the connecting plate 237 is fixedly connected to the welding gun 236. The water pump 238 can allow the liquid inside the water tank 233 to be sprayed to the welding point between the welding gun 236 and the steel structure, thereby cooling it.

[0029] A water storage tank 11 is provided on the upper surface of the machine base 1, a drain outlet 13 is provided on the inner wall of the water storage tank 11, a plate groove 12 is provided on the inner wall of the water storage tank 11, a filter plate 14 is provided inside the plate groove 12, and a handle 15 is fixedly installed on one side of the filter plate 14. The water storage tank 11 is directly below the lifting plate 23. The sprayed liquid can be filtered through the filter plate 14 and then discharged through the drain outlet 13.

[0030] Working principle: When it is necessary to clamp the steel structure, after placing the steel structure into the inner ring of the rotating disk 36, start the motor 392 to allow the threaded rod B393 to move the moving block 394 and the side plate 395, and the side plate 395 will rotate with the inner ring 396. When the inner ring 396 rotates, the outer ring 3962 will also rotate accordingly. As the outer ring 3962 rotates, since the fixed column 3965 is fixedly installed on one side of the rotating disk 36, and one end of the splint 3967 is movably mounted on the outer surface of the cross bar 3966, one end of the splint 3967 will rotate with the cross bar 3966 as the center of the circle, and the other end of the splint 3967 will slowly contact the steel structure until all three sets of splints 3967 all support the steel structure, and the steel structure is now fixedly clamped. At this time, the electric telescopic rod 22 and the motor 232 can be started to move the welding gun 236 to the junction of the two sets of steel structures so as to weld them. When the welding gun 236 is welding, the water pump 238 will extract the liquid inside the water tank 233, thereby spraying it onto the surface of the steel structure to cool it down. The sprayed water will eventually pass through the filter plate 14 for filtration, then fall into the water storage tank 11, and finally be discharged from the drain port 13. After one surface of the steel structure is welded, the rotating disk 36 can be manually rotated to rotate the rotating disk 36 with the steel structure. When the rotating disk 36 has finished rotating, the clamping rod 35 will be clamped into the clamping hole 38 to fix the rotating disk 36, thereby achieving the effect that the required welding surface can be conveniently adjusted when welding the steel structure.
