Description

Motor has upset instrument of winding stator core

Technical Field

The utility model relates to a motor manufacturing technology field specifically is a motor has winding stator core's upset instrument.

1. In the process of motor production, according to the process requirements, the motor stator is often in different placement states, for example, when the stator is embedded into a coil, the stator core is horizontally placed; when the stator with the winding iron core is assembled into the motor base, the stator with the winding iron core is required to be in a vertical position. The invention is a special process device applied to overturning and placing the winding iron core of the motor in different states.

2. In the existing scheme, a hoisting ring screw is screwed into a screw hole at one end of an excircle welding rib of a motor winding iron core for overturning the motor winding iron core, and the hoisting ring screw is used for hoisting so that a motor stator is in a vertical state. And then placed into a seat ring to be assembled.

3. The prior art has the following defects:

(1) in the hoisting process, because the hoisting point is at one end, when the winding core is hoisted from a horizontal state to a vertical state, the hoisted winding core of the motor can shake and swing, so that personal safety hazards exist.

(2) The suspension screws of larger dimensions cannot be screwed in the end planes of the stator bars due to the limitation of the winding ends. The lifting ring screw is screwed in the excircle of the stator rib, and the plane of the lifting ring screw cannot be well attached to the stator rib due to the fact that the excircle of the rib is a cylindrical surface, and the stress state is not good. When the lifting bolt is lifted, the lifting bolt is simultaneously acted by tension and shearing force, for a large motor, the weight of a motor stator is heavy, the lifting bolt cannot be lifted safely and stably (see GB-825 maximum lifting weight when the lifting bolt is lifted stably), and the lifting bolt is extremely unsafe.

(3) When the motor winding iron core is temporarily and vertically placed to be installed in a motor base, the motor winding iron core needs to be placed on a base ring to protect the end part of a winding. The distance between the seat ring and the winding is small under the influence of the size of the winding end, so that the winding end is easy to be damaged in the placing process, and the electric fault of the motor is caused.

The invention aims to overcome the defects of the prior art, and provides a method for realizing safe overturning and placing by utilizing special process equipment in order to solve the problem that a stator is provided with a winding iron core.
