Vertical paint dipping mould for stator of permanent magnet synchronous roller motor
Technical Field
The invention relates to the field of mining motors, in particular to a vertical paint dipping mould for a motor stator.
Background
In recent years, the development of new types of motors represented by permanent magnet synchronous motor drums has become more and more important in domestic and foreign markets.
The permanent magnet synchronous electric roller adopts the latest electromagnetic scheme and the latest structural scheme, the rotor component is arranged outside the stator component, and the stator component is connected with the spoke plate shaft.
Compared with the horizontal paint dipping, the horizontal paint dipping mode has more insulating paint in the paint dripping process, so that the insulating paint die is not uniform, and the paint film is thicker at the upper part and the lower part of the winding; this situation not only causes waste of the insulating varnish but also causes a phenomenon of drying cracking of the insulating varnish, thereby causing a reduction in the service life of the motor. Therefore, when the paint dipping mode is selected, the vertical paint dipping mode is preferably selected. The permanent magnet synchronous electric roller adopts the latest electromagnetic scheme and the latest structural scheme, the rotor assembly is arranged outside the stator assembly, the stator assembly is connected with the spoke plate shaft, the weight of the stator is increased, the paint dipping length is greatly increased, and paint is prevented from flowing into the spoke plate shaft in the paint dipping process, so that the traditional mould cannot be used for stator paint dipping work.
Disclosure of Invention
In order to solve the problems, the invention discloses a vertical paint dipping mould for a stator of a permanent magnet synchronous roller motor.
The specific technical scheme is as follows:
a vertical paint dipping mould for a permanent magnet synchronous roller motor stator comprises a base, a lower cover plate, a clamping ring and an upper end cover;
the lower cover plate is tightly fixed at the lower shaft end;
the clamping ring clamps the upper line hole of the shaft;
the upper end cover is connected with the upper shaft end through a bolt;
the base supports the stator; the lower end of the base is of a circular ring structure, and vertical ribs are arranged around the base; the upper end of the base is provided with a protective ring, a hoisting plate and a supporting seat, and the supporting seat is supported at the positioning end of the amplitude plate shaft.
And a rubber pad is arranged between the lower cover plate and the lower shaft end.
The clamping ring clamps the wire inlet hole on the shaft through the bolt and the nut, so that the paint is prevented from entering the shaft from the wire inlet hole on the shaft when the paint is dipped.
The lower cover plate is tightly fastened at the lower shaft end through a bolt.
A hanging ring is fixed on the upper end cover.
The invention has the advantages that: the vertical paint dipping tire greatly improves the space utilization rate of the paint dipping tank and the baking oven, improves the production efficiency, reduces the energy consumption in the paint dipping process, ensures the uniform thickness of an insulating paint film, and prolongs the service life of a motor.

Detailed Description
The invention is described in detail below with reference to the accompanying drawings, and as shown in the figures, the vertical paint dipping mould for the permanent magnet synchronous roller motor stator comprises a base 1, a lower cover plate 2, a bolt 3, a clamping ring 4, a nut 5, an upper end cover 6 and a hanging ring 7. The lower cover plate 2 is tightly fastened at the lower shaft end 12 by using a bolt 3, and a rubber pad 8 is padded in the middle; the clamping ring 4 clamps a shaft upper line hole 9 through a bolt 3 and a nut 6, and a rubber pad 8 is arranged in the middle; the rubber cushion 8 can effectively prevent paint from entering the shaft from the position of the upper line hole 9 of the shaft when the paint is dipped, and can also effectively prevent the shaft surface from being abraded; the upper end cover 6 is matched with the upper shaft end 13 and is connected and fastened by a bolt 2 through a hole 17; the lifting ring 7 is connected with a lifting threaded hole 18 on the upper cover plate 6; the stator is hung in the base 1; the lower end of the base 1 is of a circular ring structure, and the vertical ribs 101 are arranged on the periphery of the base, so that paint dipping conditions can be observed conveniently, and meanwhile, paint accumulation can be reduced; the upper end of the base 1 is provided with a protective ring 14, a hoisting plate 15 and a supporting seat 16, and the coil 10 is prevented from colliding, so that the supporting seat 16 is arranged in the structure and supported at the positioning end 11 of the amplitude plate shaft, and the stator can be effectively prevented from colliding in the hoisting process. The motor stator is high in overall height due to the fact that paint is soaked on the motor stator with the shaft, the distance between a crane is not enough, a hoisting plate 15 and a protective ring 14 are arranged at the upper end of a hoisting base 1, and the upper shaft end portion is not required to be hoisted during hoisting, so that the hoisting height is greatly reduced while the outline of the stator is fully protected.
