[0024] Combination Figure 1-Figure 3The joint welding machine with automatic grinding structure shown in the figure comprises a support structure 1, a fuselage 2 is arranged above the support structure 1, the support structure 1 comprises support columns 11, the number of support columns 11 is four, the support columns 11 are arranged at the four corners of the bottom of the fuselage 2, the bottom of the support columns 11 are all provided with anti-skid bases 12, and the support structure 1 supports the fuselage 2 firmly. A control panel 3 is arranged on one side of the outer wall of the fuselage 2, a moving structure 4 is arranged on one side above the fuselage 2, a clamping and rotating structure 5 is arranged at both ends above the fuselage 2, and a grinding device 6 is arranged on one side of the clamping and rotating structure 5. The clamping and rotating structure 5 includes a first fixed block 501 and a second fixed block 502, which are both fixedly arranged at two ends above the fuselage 2, and through holes 503 are provided inside the first fixed block 501 and the second fixed block 502. The inner walls of the first fixed block 501 and the second fixed block 502 are rotatably connected with a first clamping tube 504 and a second clamping tube 505 respectively through bearings, and four micro electric telescopic rods 506 are evenly arranged on the inner walls of the first clamping tube 504 and the second clamping tube 505, and the ends of the micro electric telescopic rods 506 are connected with rubber arc plates 507. A rotating motor 508 is provided at one end of the outer wall of the first fixed block 501, and a rotating gear 509 is directly connected to the driving end of the rotating motor 508. A rack 5010 is provided on the outer wall of the first clamping tube 501, and the rotating gear 509 is meshed with the rack 5010. A lifting structure 5011 is provided between the first fixed block 501 and the second fixed block 502. Before welding the pipe fittings, firstly, the pipe fittings to be welded are passed through the perforation 503 and placed into the first clamping tube 504 and the second clamping tube 505. At this time, the micro electric telescopic rod 506 extends to drive the rubber arc plate 507 at the end to move to squeeze and fix the pipe fittings placed therein to keep them stable. The lifting structure 5011 includes a lifting cylinder 50111. There are two lifting cylinders 50111. The lifting cylinders 50111 are fixedly arranged above the fuselage 2. An arc support plate 50112 is fixedly connected above the lifting cylinders 50111. The end of the pipe fitting to be welded is placed on the arc support plate 50112. The piston end of the lifting cylinder 50111 moves upward to support and stabilize the arc support plate 50112 for subsequent welding work.

[0025] The moving structure 4 includes a first electric slide rail 41, which is provided on one side above the fuselage 2, a column 42 is slidably connected to the first electric slide rail 41, a crossbeam 43 is connected to the top of the column 2, a second electric slide rail 44 is provided on the crossbeam 43, a moving block 45 is slidably connected to the second electric slide rail 44, a lifting cylinder 46 is provided below the moving block 45, and a welding head 47 is connected to the bottom of the lifting cylinder 46. After the pipe is clamped and fixed, the control panel 3 controls the moving structure 4 to drive, the column 42 moves in the vertical direction through the first electric slide rail 41, the moving block 45 can drive the welding head 47 to move in the horizontal direction through the second electric slide rail 44, and the piston end of the lifting cylinder 46 drives the welding head 47 below to move up and down to adjust the appropriate welding height. After one side of the pipe fitting is welded, it needs to be rotated to facilitate full welding. At this time, the rotating motor 508 drives the rotating gear 509 to rotate. Since the rotating gear 509 is engaged with the rack 5010 outside the first clamping tube 504, the first clamping tube 504 and the second clamping tube 505 are rotatably connected to the inner walls of the first fixed block 501 and the second fixed block 502 through bearings. Therefore, when the rotating gear 509 rotates, it will also drive the first clamping tube 504 and the second clamping tube 505 to rotate, and the pipe fittings clamped in the first clamping tube 504 and the second clamping tube 505 will also rotate accordingly, and the welding head 47 can fully weld the pipe fitting.

[0026] Combination Figure 1 and Figure 3 As shown, the grinding device 6 includes a rectangular groove 61, which is opened on one side above the fuselage 2.

After the pipe is welded, the weld on the surface of the pipe needs to be polished to make the surface smoother. At this time, the rotating motor 508 is still driven and the pipe continues to rotate. At this time, the driving motor 63 drives the screw rod 62 to rotate. The slider 64 has a thread that matches the screw rod 62. Therefore, when the screw rod 62 rotates, the slider 64 will move along the direction of the screw rod 62. After the slider 64 moves to the position of the weld connection, the hydraulic telescopic rod 66 drives the grinding bracket 67 on the top to adjust the appropriate height and angle until the grinding wheel 68 can contact the weld of the pipe. At this time, the grinding motor 69 drives the rotating shaft to rotate, and the grinding wheel 68 on the rotating shaft will rotate rapidly to grind around the weld of the pipe. Since the pipe is in a rotating state, the weld of the pipe will eventually be fully polished.
