Jig for motor core static motor powder coating and motor core static motor powder coating method

Abstract

The invention relates to a jig for motor core static motor powder coating and a motor core static motor powder coating method. The jig for motor core static motor powder coating is characterized in that a motor core comprises an annular core body, wherein the annular core body comprises a plurality of core units which can be mutually spliced to form an annular structure, each core unit comprises ayoke part and a tooth part which extends from the yoke part along the radial direction to form inner teeth of the annular core body, the jig comprises a positioning assembly, the positioning assemblycomprises a positioning main body, at least one positioning groove is formed on an outer side wall of the positioning main body, the shape and the size of the positioning groove are matched with theshape and the size of a yoke part of the core unit, the yoke part is clamped into the positioning groove, the tooth part protrudes out of an outer side wall of the positioning body in the radial direction. The jig is advantaged in that the powder coating procedure of the motor core with the internal teeth can be simplified, and powder coating efficiency and powder coating precision are improved.

Description

technical field [0001] The invention relates to the field of motor manufacturing, and more specifically relates to a jig for powder coating of a motor iron core electrostatic machine and a powder coating method for a motor iron core electrostatic machine. Background technique [0002] At present, the iron core used in the motor generally needs to coat the contact surface with the coil winding with insulating powder, so as to be insulated from the coil winding. In the prior art, clamps are generally used to clamp the iron core at both ends of the iron core for the iron core with external teeth, and then the assembly is sent to an electrostatic machine for powder coating. However, for iron cores with internal teeth, this method cannot be applied, and it is easy to cause the outer surface of the yoke of the iron core and the inner wall of the teeth to stick to the insulating powder, which affects the use of the iron core. At present, the iron core with internal teeth generally...

Problems solved by technology

However, for iron cores with internal teeth, this method is not applicable, and it is easy to cause insulating powder to stick to the outer surface of the yoke of the iron core and the inner wall of the teeth, affecting the use of the iron core

At present, the iron core with internal teeth generally uses a mask to cover the surface that does not want to be coated, but this method has disadvantages such as cumbersome operation and low efficiency.
