Description

Rotor machining device

Technical Field

The invention belongs to the technical field of rotor machining, and particularly relates to a rotor machining device.

Background

The motor is a device for converting electric energy and mechanical energy, and mechanical energy and electric energy. The motor consists of a rotor and a stator, wherein the rotor is a rotating part in the motor and consists of a rotor core, a rotor winding, a rotating shaft and other parts, and the function of the motor is to obtain a rotating torque under the action of a rotating magnetic field.

In the mechanical field, the rotor of the alternator needs to be subjected to rust-proof processing, namely, a layer of rust-proof paint for preventing oxidation is coated on the outer circumference of the winding post of the rotor so as to ensure the normal operation of the motor. At present, the rust-proof processing of the rotor mostly adopts the painting operation, and specifically comprises the following steps: and spraying the liquid anti-rust paint by a high-pressure airflow atomizing gun, and attaching the liquid anti-rust paint to the surface of the sprayed rotor winding post to form a fixed paint film.

Above-mentioned mode of adopting the spraying paint, because can have a large amount of atomizing lacquer liquid dispersed everywhere at atomizing spun in-process for the benzene concentration in operation place is very high, has seriously polluted the environment, still can cause serious harm to workman's healthy simultaneously, flies to the atomizing lacquer in the air in addition and does not carry out recycle again well, consequently makes the cost input of enterprise improve.
