Positioning device of insertion piece type impeller forming machine

Abstract

The invention discloses a positioning device of an insertion piece type impeller forming machine. The positioning device is arranged on a base of the insertion piece type impeller forming machine and is characterized by further comprising locking mechanisms, a linkage ring, first cylinders and push heads, wherein each locking mechanism comprises a rocking bar, a first fixing block and a second fixing block, one end of the rocking bar is movably hinged and connected with the first fixing block which is fixedly connected with the linkage ring, a positioning column which can be inserted into a positioning hole of a lower gland of an impeller for positioning is arranged at the other end of the rocking bar, a convex shaft is arranged in the middle of the rocking bar, the rocking bar is hinged and connected with the second fixing block through the convex shaft, the second fixing block is fixedly connected with the bottom of a mold, the push heads are arranged below the linkage ring, and the first cylinders drive the push heads to move up and down. The positioning device has the advantages as follows: the structure is simple, the operation is convenient, accurate positioning between a slotted hole of the lower gland and an inserted slot of the mold can be guaranteed, the precision and the accuracy of the insertion piece are improved, the product quality is guaranteed, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to a positioning structure, in particular to a positioning device for a lower gland of an insert-type impeller forming machine. Background technique [0002] In the prior art, the existing Chinese utility model patent "A Metal Fan Impeller Automatic Assembly Machine" with the patent number ZL201020606311.X discloses a processing equipment for metal cross-flow fan impellers. The metal fan impeller automatic assembly machine includes A frame and a blade cutting mechanism, a blade threading mechanism, an impeller blade inserting mechanism and a middle disk dividing mechanism installed thereon. The patented impeller assembly machine only needs to put the shaped blades into the blade cutting mechanism, put the middle plate into the middle plate dividing mechanism, and the blade cutting mechanism, blade threading mechanism, impeller inserting mechanism and the middle plate on the frame The sub-disk structure works sequentially, and all...

AI Technical Summary

Problems solved by technology

This manual insertion method cannot achieve reliable positioning of the lower gland. During the insertion process, the movement of the lower gland will cause uneven spacing between the blades. It is often necessary to adjust the distance between the blades after all the blades are inserted. spacing, resulting in low work efficiency and high assembly costs
