Impeller assembly machine for multi-blade centrifugal fan

Abstract

The invention discloses an impeller assembly machine for a multi-blade centrifugal fan. The impeller assembly machine comprises a workbench, a vertical post and a beam, wherein a power device and a main shaft are arranged in the workbench; an impeller mold is connected to the main shaft; a feeding cylinder and a spinning frame fixed on a piston of the feeding cylinder are fixedly arranged on the vertical post; two spinning cylinders and spinning wheel components fixed on pistons of the spinning cylinders are fixedly arranged on the spinning frame; the positions of the two spinning wheel components are on the same vertical protection surface; each spinning wheel component is rotatably connected with a spinning wheel; a tightening cylinder and a tightening block fixed on a piston of the tightening cylinder are fixedly arranged on the beam; and the center of the tightening block and the center of the impeller mold are on the same axis. An initially-assembled impeller is fixed on the impeller mold and tightly clamped by the spinning wheels of the two spinning wheel components, and fixed end pieces at the two ends of the impeller are respectively bent at one time and fixed between a front disc and a rear disc, so the working efficiency is greatly improved, and the assembly quality of the impeller is improved.

Description

technical field [0001] The invention relates to a manufacturing equipment of a multi-blade centrifugal fan, specifically an assembly machine for assembling the blades of the impeller of the multi-blade centrifugal fan and the front and rear discs. Background technique [0002] The multi-blade centrifugal fan impeller includes a front disk, a rear disk and several blades evenly distributed along the outer edges of the front and rear disks. The two ends of the blades are provided with fixed end pieces slightly smaller than the transverse size of the blades. The fixed end pieces of the blades Insert into the fixing holes evenly distributed on the outer edges of the front and rear discs and bend in the plane direction of the front and rear discs, so that the blades are fixed between the front and rear discs. [0003] The assembly of the existing multi-blade centrifugal fan impeller is basically manual operation. The operator inserts the fixed end pieces of the blades into the fi...

AI Technical Summary

Problems solved by technology

[0003]The assembly of the existing multi-blade centrifugal fan impeller is basically manual operation. In the distributed fixing holes, the fixing blocks are bent by simple tools such as hammers. Using this assembly method, on the one hand, the assembly process takes a long time and the production efficiency is extremely low. On the other hand, due to the The force used for bending the fixed block is not the same, which causes each blade of the impeller to be fixed differently from the front and rear discs, which affects the quality of the impeller
