Adjustable type varnish stripping device of high-performance stator

Abstract

Provided is an adjustable type varnish stripping device of a high-performance stator. The adjustable type varnish stripping device of the high-performance stator comprises a power source used for providing rotating power and a varnish knife which is driven by the power source, wherein the varnish knife comprises a rotating shaft which is used for carrying a varnish knife body and is connected with the power source, the output end of the rotating shaft is fixedly connected with a knife rest, a knife rod is connected on the knife rest in a hinge joint mode through a fulcrum, a varnish stripping end which is used for removing insulation varnish from the surface of a varnished wire, a heavy bob is arranged at the other end of the knife rod, and the torque of the heavy bob corresponding to the fulcrum in a direction far away from a center shaft of the rotating shaft is larger than the torque of the varnish stripping end corresponding to the fulcrum in a direction far away from the center shaft of the rotating shaft. Through determination of rotating speed of the high-speed varnish knife, the pressure of the varnish knife to varnished wires with any diameter is constant, and copper wires inside the insulated varnish are not damaged.

Description

technical field [0001] The invention relates to an adjustable paint stripping device for a high-performance stator, which belongs to the field of generator and motor manufacturing. Background technique [0002] The stators of high-performance generators and high-performance motors are mostly made of enameled wires, and the wire ends of the coils composed of enameled wires need to be welded and other operations, so the insulating varnish on the wire ends must be stripped. The traditional craft is to peel off the paint by hand, but because the diameter of the enameled wire is relatively small, it is very easy to damage the inner copper wire by hand. Once the copper wire of the stator is damaged, the welding will not be firm enough during installation, and the hidden danger of poor contact will be introduced. Moreover, the current has a skin effect. When the current flows through the copper wire, it tends to concentrate on the surface of the copper wire, and the surface of the ...

Problems solved by technology

However, each blade of this paint stripping mechanism needs to be manually adjusted, which is inconvenient to use and the adjustment accuracy is not high. It is very easy to cause incomplete paint stripping due to improper adjustment or damage to the copper wire in the paint due to excessive adjustment.
