The invention relates to the technical field of production of fan impellers and particularly relates to a correcting device for concentrically welding fan impellers. The correcting device comprises a base, wherein a socket is rotatably mounted on the top surface of the base through a rotating bearing; a transverse insertion hole is formed in the center of the socket; a shifting rod is inserted in the insertion hole; a fixing disc is arranged at the top end of the socket; a straight-tooth bevel gear combination is arranged in the fixing disc; a screw is led out of the interior of the straight-tooth bevel gear combination; a nut sleeve is arranged on a rod body of the screw in a threaded fit mode; and adjusting rulers are arranged at the top end of the nut sleeve.Through the correcting device for concentrically welding the fan impellers, the problems that coaxial centers of wheel discs can not be ensured and the quality of product is influenced when the fan impellers are assembled are solved; when the correcting device is used, the positions of the wheel discs placed on the adjusting rulers can be finely adjusted through the shifting rod, the radial moving distances of the adjusting rulers can be changed; and finally, the situation that all the wheel discs are coaxially welded can be guaranteed; and the machining quality of the products is obviously improved.
Description
technical field [0001] The invention relates to the technical field of fan impeller production, in particular to a fan impeller concentric welding correction device. Background technique [0002] At present, the metal impellers used for blowers generally include a central disk and blades fixed on the bottom plate. The blades are evenly distributed along the circumference of the bottom plate. The assembly method of the impeller is to weld different disks concentrically to form an impeller. This design structure has the advantages of Sufficient durability, but such a design needs to ensure the concentricity of each wheel disc. Under the existing technology, the concentricity of the fan impeller is not accurate, and there are often errors, which will eventually affect the quality of the product and affect the actual use of the product . Contents of the invention [0003] The purpose of the present invention is to solve the defect in the prior art that the concentricity of th...
