技术领域technical field
本发明涉及电机制造领域，更具体地说，涉及一种电机铁芯静电机涂粉用的治具及电机铁芯静电机涂粉方法。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.
背景技术Background technique
目前用于电机的铁芯一般需要在与线圈绕组接触的接触面上涂覆绝缘粉，以便于与该线圈绕组绝缘。而现有技术中，对于具有外齿的铁芯一般都是采用夹具置于铁芯的两端将该铁芯夹住，然后将该组合件送至静电机中进行涂粉。而对于具有内齿的铁芯，该种方法则无法适用，其容易导致该铁芯的轭部外表面以及齿部的内侧壁粘有绝缘粉，影响该铁芯的使用。目前对具有内齿的铁芯一般采用掩模覆盖不希望涂装的表面进行涂粉，但是该种方法，存在操作繁琐、效率低下等弊端。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 uses a mask to cover the undesired surface for powder coating, but this method has disadvantages such as cumbersome operation and low efficiency.
