Description

technical field [0001] The invention relates to the field of fan impeller tooling equipment, in particular to a tooling device for high-end axial flow fan impeller high-precision welding. Background technique [0002] The impeller of the axial flow fan includes a hub part and multiple blade parts. Currently, it is processed for welding with the impeller, such as figure 1 As shown, the main thing is to install the hub into the corresponding equal plate, and then choose the inclination angle corresponding to the model and take the center line as the reference for welding work. Every time the spot welding is completed, each blade needs to be dragged by hand. The chassis and the mold with an inclination angle are used for spot welding of the second blade, and so on. [0003] The analysis of the above-mentioned welding processing method for the impeller is as follows: [0004] 1. Since the axial flow fan uses special tooling in the welding process, it is necessary to select the...

Problems solved by technology

[0004] 1. Since the axial flow fan uses special tooling in the welding process, it is necessary to select the appropriate special tooling according to different types of blades each time. During each use, the tooling transfer and debugging need to waste a lot of working time for the operator ;

[0005] 2. Due to the manufacturing error of the blade and impeller in the spot welding process, it is difficult for the operator to ensure the uniformity of the blade shape and size in the absence of a reference point, resulting in the imbalance of the impeller and affecting the performance;

[0006] 3. The workpiece needs to be welded at frequently changing angles. During the welding process, it is mainly due to the platform limitation and the singleness of the blade mold that the operator often changes the angle, which indirectly increases the labor intensity and reduces the concentration of the work.
