Description
Technical Field
The utility model relates to a stator bush machining tool field says in detail is a processingequipment of special motor stator bush.
Background
As is known, a motor is composed of a stator and a rotor, and a special motor requires a weight as light as possible and a stator bushing as thin as possible, so that the thickness of the stator bushing needs to be controlled within 0.5 mm. However, the stator bush is required to be not only thin but also to have strict tolerance control for its respective dimensions, and particularly, the roundness of the outer circle and the inner hole is required to have a dimensional variation range of 0 to 0.012. This is because the rotor is mounted inside the liner, and the gap between the stator liner and the rotor affects the efficiency of the rotor in converting electrical energy, so the roundness of the liner is particularly important. The thinner the workpiece, the more difficult it is to control the deformation, so that the thickness and roundness of the stator bushing are ensured, which becomes a processing difficulty of the stator bushing.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a processing device of a special motor stator bush, simple structure and convenient use, and can improve the labor efficiency when batch production is carried out.
The utility model provides a technical scheme that its technical problem adopted is: a processing device for a stator bush of a special motor comprises an inner hole processing device and an outer circle processing device and is characterized in that the inner hole processing device is provided with an outer sleeve, one end inside the outer sleeve is provided with a limiting step, the other end surface of the outer sleeve is provided with a fixing bolt and a limiting block, the stator bush is arranged in the outer sleeve, and the stator bush is fixed by the limiting step and the limiting block; the excircle processing device comprises a supporting shaft, wherein one end face of the supporting shaft is provided with a clamping chuck, the other end face of the supporting shaft is processed with a center hole, the excircle of the supporting shaft is provided with three positioning steps, glue overflowing grooves are processed on the positioning steps, a stator bushing is sleeved outside the supporting shaft, and the supporting shaft is adhered to the stator bushing.
The beneficial effects of the utility model are that, easy operation, it is efficient, reduced intensity of labour and cost of labor, improved the machining precision again.
