The discs are stacked in a disc tray 16 tool, conveyed to a grabbing position by a double-layer lifting conveying roller line 15, grabbed by a transfer robot and a disc clamping jaw 17 and uploaded to a disc cache seat 18. Then the disc is transported to a disc positioning platform 20 by a disc transporting mechanism 19; then the disk turnover mechanism 21 turns over and positions the components to wait for assembly. After the alignment of the steel pipe is finished, the first servo moving sliding table 40 pushes forwards for one stage, after the alignment is finished, the first pneumatic tensioning inner support clamping jaw 38 is loosened, servo retraction is carried out, the lifting tip 43 descends to the center position of the steel pipe, and then the second servo moving sliding table 42 moves forwards, so that the tip contacts with the steel pipe and pushes forwards for two stages. At this time, the steel pipe is penetrated into the disc to be assembled, and the assembly of the steel pipe and the disc is completed. And finally, moving the whole body to a welding position. The sleeve is discharged by the sleeve sorting and positioning mechanism 22, conveyed to a V-shaped positioning tool 48 of the sleeve feeding mechanism 24 by the horizontal multi-joint manipulator conveying mechanism 23, transplanted in front of the three-grabbing and clamping cylinder 25 by the rodless transverse moving cylinder 50, and finally pushed into the three-grabbing and clamping cylinder 25 by the pressing cylinder 51 to clamp and position the sleeve to wait for assembly. The sleeve at the waiting position is pushed into the head end of the steel pipe by the cylinder pushing mechanism 27, and the assembly of the steel pipe and the sleeve is completed. The rotating tailstock mechanism 64 is driven by a tailstock moving servo sliding table 66 to move to the tail end of the steel pipe, and the tail end of the steel pipe is pressed against the rotating tailstock by a tailstock telescopic cylinder 65. The torch lifting mechanism 29 is lowered to move the water-cooled torch unit 28 to the welding position, and the automatic spot welding is performed. After the electric welding is finished, the disc turnover mechanism 21 resets. At this time, the product has certain strength after being spot-welded. After the spot welding is completed, the full-length welding is continued for the entire circumferential portion. During full welding, the sleeve is driven by the sleeve rotating servo mechanism 26 to rotate for a whole circle, so that the whole product is driven to rotate, and full welding is realized. After welding, all mechanisms reset, and products automatically fall to the blanking slide rail 33 and enter the material receiving slide rail 34 and are blocked by the material separating and blocking stop cylinder 35. Only one product is allowed to enter the robot material taking position. The handling robot and the finished product gripper 36 automatically stack the product gripping and handling material frame 37. After welding is completed each time, in the synchronous process of assembling products, the three-axis servo transplanting module 32 drives the automatic gun cleaning mechanism 8 to automatically clean one of the eleven sets of welding guns, and the automatic gun cleaning operation without stopping is completed by circulating in sequence.
