After the welding parts of the two tank body components come into contact, stop the second electric telescopic rod 34. Then start the first electric telescopic rod 6 to push the welding torch 7 downward so that the welding torch 7 moves to the joint of the welding parts of the two tank body components. Then start the double-shaft motor 19 to drive the transmission rod 20 to rotate. The transmission rod 20 drives the first transmission wheel 21 to rotate. The first transmission wheel 21 drives the second transmission wheel 24 to rotate through the transmission belt 22. The second transmission wheel 24 drives the sleeve rod 25 to rotate. The sleeve rod 25 drives the support rod 27 to rotate under the interaction of the sliding block 30 and the sliding groove 31. The support rod 27 drives the rotating disk 28 to rotate. The rotating disk 28 drives the circular seat 8 to rotate through the connecting column 29. The tank body components fixed on one side of the circular seat 8 rotate accordingly. At this time, the two tank body components rotate simultaneously. Then start the welding torch 7 and weld the joint between the two during the rotation of the two tank body components. In this way, the tank body welding device for hydrogen storage tank processing can achieve the effect of rapid welding during use, improve the processing efficiency, and thus achieve better practicability.
