Description
Technical Field
The invention belongs to the technical field of motor production equipment, and particularly relates to a tool for press fitting of a motor insulating sleeve.
Background
In the production process of the motor, an insulating sleeve is required to be sleeved on the rotor. The insulating sleeve is provided with a plurality of hollow winding columns (shown in figure 1) which are annularly arranged at intervals, and when the insulating sleeve is pressed on the rotor, the hollow winding columns 1 need to be aligned with slots on the rotor one by one so as to accelerate the accurate pressing operation of the insulating sleeve. The hollow winding column 1 is affected by the material and the processing conditions, and in actual operation, the deformation or the insufficient precision can be caused, especially the end part of the hollow winding column 1 can be enlarged, and the slot can not be accurately aligned during press fitting. The existing press mounting equipment is difficult to insert the corresponding hollow winding column into the slot at one time, so that the insulating sleeve is crushed, and the press mounting process of the insulating sleeve cannot be performed normally and effectively.
