The supporting square pipe 42 is pushed upward as a whole by the extension of the output end of the hydraulic cylinder 41, so that the pipe at the top of the discharge assembly 45 is driven to move, and the height of the pipe to be welded can be adjusted. The V-shaped rods 43 symmetrical on both sides are used for support, and the supporting square pipe 42 is supported by the rolling of the roller 44, so that the overall operation of the structure is stable. At the same time, when the V-shaped rod 43 is driven by the supporting square tube 42 to move upward, the bottom end of the connecting support column 51 contacts the inclined surface of the top of the V-shaped rod 43, and the V-shaped rod 43 continues to move upward, so that the supporting square tube 42 is driven to approach the arc-shaped material receiving plate 451, and the supporting square tube 42 is slidably connected with the top of the frame 1, so that the two symmetrical supporting square tubes 42 move toward each other with respect to the centering cone 53, and the tip of the centering cone 53 is inserted into the end of the pipe, so that the pipe is centered, so that the pipe to be welded is not easily deviated; At this time, the staff turns on the servo motor 454 to work, and uses the output end of the servo motor 454 to drive the cylindrical block 455 to rotate, so that the toggle rods 456 evenly distributed on the outer circumferential surface of the cylindrical block 455 are driven to rotate in a circle, and the force-bearing teeth 4574 are meshed and connected with the toggle rods 456, so that the force-bearing teeth 4574 are subjected to the toggle force of the toggle rods 456, and under the rotation connection of the rotating shaft 4571, the driving wheel 4572 is driven to rotate, and the anti-skid pattern 4573 can be used to increase the friction force, so that the pipe placed inside the arc-shaped receiving plate 451 is driven to rotate, and the rotation of the output shaft of the servo motor 454 is controlled to control the rotation speed of the pipe, and under the rolling support of the roller 453, the pipe rotates smoothly and is not prone to jamming; At the same time, the staff starts the linear drive 32 to work, and uses the output end of the linear drive 32 to drive the right-angle connecting plate 33 to move, so that the welding host 34 and the cleaning component 35 are driven to move together, and the cleaning component 35 is driven to move by the output end of the linear drive 32 as a whole, and the grinding brush 355 is stopped from moving when the grinding brush 355 is in the gap between the two pipe ports as a whole; The cylinder 31 is turned on to work, and the linear drive 32 can be driven to move downward as a whole by the extension of the output end of the cylinder 31, so that the bottom end of the grinding brush 355 can fit with the edge of the port of the outer cylindrical surface of the pipe, and the grinding brush 355 can clean the debris attached to the port of the outer cylindrical surface of the pipe by the rotation of the pipe, so that the weld can be kept clean; After the end surface of the outer cylindrical surface of the pipe is cleaned, the cleaning assembly 35 is lifted as a whole, and the linear drive 32 can be driven downward as a whole by the extension of the output end of the cylinder 31 again, so that the welding host 34 can be driven downward, and the welding head 36 can be fine-tuned, so as to accurately control the distance between the welding head 36 and the pipe, and the supporting teeth 37 are used to move the welding head 36 downward, so that the bottom end of the welding head 36 can be used to contact the top of the outer cylindrical surface of the pipe, and the welding head 36 is supported by the rolling connection of the ball 38, so that the welding head 36 is more stable as a whole, and the influence of external force and vibration is reduced, and it is not easy to shake, so that the welding head 36 can accurately weld the pipe; As the grinding, cleaning and welding proceed, the position of the weld at the end of the pipe corresponds to the position of the slag leakage hole 452, and the slag generated when cleaning and welding the pipe will fall to the position of the slag leakage hole 452, and under the guidance of the supporting square tube 42, the slag will fall to the bottom of the inner wall of the frame 1, and the slag will be gathered. After the welding of the pipe is completed, the cabinet door on the outside of the frame 1 can be opened to remove the slag leaked from the supporting square tube 42.
