Description
Technical Field
The invention belongs to the technical field of motor tools, and relates to a motor stator winding varnishing tool.
Background
The motor stator winding consists of a stator core and a stator winding, and the motor stator winding needs to be painted in order to ensure the insulation strength and the moisture resistance of the motor stator winding, improve the mechanical property, the chemical stability, the heat conductivity, the heat dissipation effect and the ageing delay of the motor stator winding. At present, the motor winding is painted mainly by three steps, namely paint dipping, paint dripping and drying, and the purpose of the paint dipping of the motor stator winding is to expel moisture contained in the stator winding firstly and fill all space air gaps with insulating paint; in order to reduce the cleaning of sticking, reserving and solidifying impregnating varnish in the later factory finishing, the motor stator winding is required to be hung with the impregnating varnish after the impregnating varnish is finished so as to reduce the amount of redundant insulating varnish on the stator core and the stator winding, and finally the motor stator winding after the impregnating varnish is finished is dried so that the insulating varnish is solidified.
In the process of finishing the painting of the motor stator winding, a fixture is needed to realize the fixation and the transportation of the motor stator winding, and as the motor stator winding has relatively heavy weight, the common fixture is used for realizing the support of the motor stator winding by arranging a support on the motor stator winding. For example, a special fixture for dip coating of a winding of a motor (grant bulletin number CN 204442123U) disclosed in chinese patent literature comprises a base and an opening collar, wherein the opening collar is connected with the base through a plurality of connecting rods, the opening inner diameter of the opening collar is larger than the outer diameter of the winding of the stator, and the inner diameter of the base is smaller than the outer diameter of the winding. In this patent, the stator windings of the motor are arranged on the base through an open collar; the motor stator winding is positioned only by abutting against the base, so that the motor stator winding is easy to incline during paint dipping, so that collision with the connecting rod occurs, and the positioning is unstable; the contact area of the base and the part where the motor stator winding is abutted is larger, and the abutted position cannot be contacted with the insulating paint, so that the situation of incomplete paint dipping can occur; in the process of paint dripping, insulating paint on the outer side of a motor stator winding can drip onto a base and gather on the base, so that the insulating paint on the position of the motor stator winding close to the base is more, the workload of subsequent treatment is increased, and meanwhile, the insulating paint cannot be dripped into a paint barrel for recycling, so that the insulating paint is wasted; the base can block part of hot air during drying, so that the drying efficiency of the motor stator winding is relatively low.
