[0027] Working principle: When in use, the moving frame 12 moves to one side of the tank body 1, and the moving seat 3 and the L-shaped frame 4 are driven to move up by the lifting mechanism. Then, after the position of the corresponding flange tube 2 is reached, the cylinder seat 44 is placed inside the flange tube 2 from above. The worker presses the push rods 45 at both ends against the inner wall of the flange tube 2, and then pulls out the moving rod 43, and then rotates the movable plate 47 so that the surface of the movable plate 47 is against the bottom wall of the flange seat, and then screws in the screw pin 46 to position the flange tube 2. After determining the axial position of the flange tube 2, the motor 5 drives the second gear 15 at the output end to rotate, and the corresponding meshing first gear 6 will drive the installation cylinder 7 to rotate. The installation cylinder 7 rotates above the outer side of the fixed shaft 8, and the corresponding sleeve seat 24 will drive the sliding The rod 25, the first slide 10 and the second slide 17 as a whole rotate synchronously. During the rotation, the roller 28 rolls in contact with the curved surface of the guide wheel 27. The irregular weld of the flange seat can be welded through the curvature. If the welding head 41 is offset during the welding process, it is adjusted by adjusting the assembly and the push assembly. In this way, the difficulty of automatic welding of the welding head 41 on surfaces that are not in the same plane can be solved, and more flange pipes 2 with different diameters can be positioned, so that when the flange pipe 2 is welded to the tank body 1, it is more convenient and efficient. During the welding process, the nozzles at both ends of the arc rod 37 at the welding head 41 can spray air in the welding area, thereby reducing the high temperature loss at the connection between the tank body 1 and the flange pipe 2.
