A Stacking Die for Rotors with Inclined Slots for Electric Motors

Abstract

The invention discloses a motor chute rotor overstowing die. The motor chute rotor overstowing die comprises an overstowing base, a stripper plate, a fixing button and a pressing head. The stripper plate is installed on the overstowing base, a fixing base A and a fixing base B are arranged on the overstowing base and located on the outer side of the stripper plate, the fixing button is installed on the upper portions of the fixing base A and the fixing base B, the pressing head is located above the fixing button and arranged on the tops of the fixing base A and the fixing base B, a guiding support A is fixed to the fixing base A through a fastener, a fixing support B is fixed to the fixing base B through a fastener, a pull rod A is installed on the guiding support A, a pull rod B is installed on the guiding support B, a positioning button fixing plate A is arranged on the outer side of the fixing base A, a positioning button fixing plate B is arranged on the outer side of the fixing base B, and the positioning button fixing plate A and the positioning button fixing plate B are provided with positioning buttons. The motor chute rotor overstowing die is suitable for production of various motors in small batches, the machining efficiency is effectively improved, the machining consistency is guaranteed, and investment of equipment and die cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a motor skewed rotor stacking mold. Background technique [0002] The existing skewed rotor manufacturing is mainly divided into two methods. One manufacturing method is that most of the motor production and development enterprises with many varieties and small batches use manual work. In this way, the electric motor is punched with a common composite die, the surface of the punch is sprayed with adhesive and dried, and then the punch is manually stacked into the mandrel with the mandrel and the fixed key, and the punch is manually twisted after stacking. Twist the iron core at a certain angle, press it with a hand press, fasten it, and bake for 4 hours. After the iron core is unloaded from the mold, remove the glue that overflowed during drying in the tank by hand, and the iron core after repairing The core is inserted into the motor shaft and pressed in...

AI Technical Summary

Problems solved by technology

Similarly, this die tooling device cannot solve the problem of precise positioning and angle consistency of the angle of the iron core chute. Since the angle is determined by manual rotation, the error is relatively large, and the angle of the chute is highly discrete, so the chute angle cannot be achieved. At the same time, it will cause poor stability of the motor, floating current, high scrapping rate of the armature, and difficulty in debugging

[0007] To sum up, the existing stacked molds only complete the processing of the iron core, the positioning accuracy is low, and the consistency of the angle of the chute is poor, and manual rotation is required to control the angle of the chute

The positioning method adopts the two-point positioning of the mandrel and the positioning key, and the positioning reliability is poor

The height of the iron core needs to be manually measured and adjusted to the size requirements, and the processing efficiency is low; at the same time, the positioning method is the positioning method of the mandrel positioning and positioning keys, resulting in cumbersome disassembly of the tooling, low processing efficiency, and high labor intensity for workers
