In traditional technology, the hub is mostly manually marked and graduated. The accuracy of the graduation has a certain error, and the efficiency of manual marking is low; the blade profile is a curve, and there is a certain error in the verticality of the blade when it is welded with a square ruler; the impeller is hung on the fixed shaft of the welding tool and needs to be rotated to the best welding position, which increases the workload of the operator and is not conducive to large-scale production. It is urgent to develop an axial flow fan impeller welding tool to overcome the shortcomings in current practical applications. Summary of the invention

[0007] The processed hub is placed on the support platform of the hub positioning shaft, and the hub is fixed to the hub positioning shaft with a quick-fix nut. The blades to be welded are fixed to the positioning guide grooves of the four-claw disk. After determining the position and direction, the first blade can be welded to the hub. Then the blade is released and the control box is operated to start the servo motor. The servo motor drives the hub on the hub positioning shaft to rotate an angle, and then the next blade is put in for welding. Repeat the above operation to weld all the blades to the hub.

[0008] Compared with the prior art, the utility model has the following beneficial effects: it overcomes the error caused by manual marking and grading on the wheel rim, has high precision, improves work efficiency, reduces the workload of operators, and is conducive to large-scale production.
