The staff starts the cylinder 373 to work, and uses the extension of the telescopic end of the cylinder 373 to push the welding gun 375 downward, and fine-tune the distance between the welding gun 375 and the box to be welded, and uses the output end of the linear driver 371 to drive the connecting frame 372 to move, and under the connection of the cylinder 373, the welding gun 375 moves linearly; The welding gun 375 is installed on the rotating end of the rotating workbench 374, and the rotating end of the rotating workbench 374 can be rotated to drive the welding gun 375 to rotate together, so that the angle of the welding gun 375 can be adjusted to facilitate welding of the welds on both sides; The fan-shaped baffle 376 is installed near the welding gun 375, and as the rotating workbench 374 drives the welding gun 375 to move downward, the fan-shaped baffle 376 moves downward together, so that the fan-shaped baffle 376 and the welding gun 375 move synchronously, and the fan-shaped baffle 376 is hingedly installed, and the bottom end of the fan-shaped baffle 376 is in contact with the box to be welded, and the fan-shaped baffle 376 is rotated to adjust the angle, so that the structure will not get stuck during operation, and the fan-shaped baffle 376 is used to shield the welding gun 375 during welding, so that it is not easy to cause welding slag splashing; And by utilizing the movement of the moving trolley 32, the support member 33 can be driven to move together, so that the welding assembly 37 can move together, and the position of the welding assembly 37 can be adjusted, and the box body of the flange ball valve building pressure regulating box can be welded; When welding is completed, the hydraulic cylinder 34 is turned on again to work. The welding gun 375 can be lifted by extending the telescopic end of the hydraulic cylinder 34, and the servo motor 42 is turned on again to work. The output end of the servo motor 42 rotates in the opposite direction, so that the clamping head 46 moves in the opposite direction as a whole, the box is loosened, and the welded box can be removed.
