The motor two 519 drives the pressure plate 517 to rotate to fit with the blade body 513 placed on the bonding plate 540, so as to fix the blade body 513. Before starting welding, the motor five 539 is started. The motor five 539 drives the screw rod one 531 and the screw rod two 533 to rotate, so that the connecting piece one 537 and the connecting piece two 538 drive the support plate 522 to slightly adjust the position. Adjust to make the welding point position of the connection between the hub body 512 and the blade body 513 optimal. After the blade and the hub are fixed and positioned in the positioning and fixing module 5, start the vertical hydraulic rod 601, the output end of the vertical hydraulic rod 601 extends and drives the mounting block 602 to descend. When the welding gun 607 on the fitting 605 descends to the lowest point where it can contact the connection between the blade and the hub, start the welding gun 607 for welding, start the motor 603, and the motor 603 drives the fitting 605 to rotate. With the inclination angle of the joint between the blade and the hub, the fitting 605 is lifted by the vertical hydraulic rod 601. After welding is completed, the welded fan blade and hub are taken out of the device to prepare for the next welding.
