Assembling process of motor with square iron core and steel plate shell

Abstract

The invention relates to an assembling process of a motor with a square iron core and a steel plate shell. The assembling process comprises the steps that 1, the shell is manufactured, wherein shell blanking sizes and welding and shaping moulds are adjusted according to the requirement of the roundness of motor sizes, and the shell is manufactured through blanking, punching, rounding, welding, shaping and plane chamfering; 2, a stator is pressed into the shell, wherein a stator pressing guiding mould and a fit clearance between the stator and the shell are adjusted, and the guiding mould is used for pressing the stator into the shell in a small interference fit mode; 3, dies are used for coining and locating of the stator and the shell, wherein a coining die is used for shearing and coining of the shell with the two ends of the stator core as coining male dies, and the stator core is fixed on the shell through coining; 4, the whole motor is assembled, wherein the stator after coining is directly assembled with a rotor and an end cover to form the whole motor. The process is reasonable in design, simple, easy to operate, high in assembling quality and capable of improving assembling efficiency by 20%.

Description

technical field [0001] The invention relates to the technical field of motor assembly technology, in particular to a square iron core steel plate shell motor assembly technology. Background technique [0002] The current production of steel plate casing motors, the casing is made of steel plate rolling and welding, the stator core is laminated with a square iron core, after the stator is pressed into the steel plate casing, the end face of the inner hole of the turning casing is positioned with the inner hole of the stator, so that the motor The inner hole of the stator is concentric with the spigot of the casing to ensure the uniform air gap between the rotor and the stator, that is, the light spigot process. However, in order to prevent the relative rotation between the casing and the stator, this process generally requires a large interference between the stator and the casing. After the stator is pressed into the casing, the deformation of both ends of the casing is larg...

Problems solved by technology

However, in order to prevent the relative rotation between the casing and the stator, this process generally requires a large interference between the stator and the casing. After the stator is pressed into the casing, the deformation of both ends of the casing is large, and the difference between the straight sides of the stator and the round edge of the casing is 0.50mm, and the optical seam process is cumbersome to operate and low in efficiency, and the light seam process is difficult to clean when the iron is cut into the wire bag, which should cause the motor stator to withstand voltage breakdown, and the product has quality problems
