Rotor hole pushing equipment capable of avoiding excessive hole forming for three-phase motor machining

Abstract

The invention discloses rotor hole pushing equipment capable of avoiding excessive hole forming for three-phase motor machining, and relates to the technical field of three-phase motor machining, in particular to a machining frame and a hole forming assembly, an adjusting motor is assembled at the top of the machining frame, and electric lifting rods are arranged on the two sides of the bottom face of a transmission disc. The tapping assembly is fixed to the bottom of the electric lifting rod, and a rotor body is placed at the bottom of the machining frame. According to the rotor hole pushing equipment capable of avoiding excessive hole opening for three-phase motor machining, the action track of the milling cutter head is synchronously limited from the physical level, so that the stability of the milling cutter head during moving is improved, too large hole opening caused by shaking is avoided, the distance size between the milling cutter head and the bottom of a rotor body is further measured in real time during hole opening, and the machining precision is improved. And furthermore, the milling cutter heads with different action tracks can be used by replacing the first shaping piece and the second shaping piece of the shaping piece tooth edges with different shapes, so that the milling cutter head can adapt to different trepanning shapes.

Description

technical field [0001] The invention relates to the technical field of three-phase motor processing, in particular to a rotor hole-pushing device which can avoid excessive drilling for three-phase motor processing. Background technique [0002] The rotor is an important part of a three-phase motor. The rotor of a three-phase motor is generally composed of an iron core with coils, a slip ring, and a fan blade. The surface of the rotor often has holes evenly distributed for winding, and these holes are usually It is formed by turning the milling cutter and pushing it down to stick to the surface of the rotor to open holes, and the equipment for this hole opening operation is called pushing hole equipment. [0003] The existing hole pushing equipment generally uses software to control the movement trace of the milling cutter so that the holes on the surface of the rotor form a shape consistent with the trace, but this method has weak control over the milling cutter and its shaf...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a rotor-pushing device for machining three-phase motors that can avoid excessive drilling, which solves the problem that the conventional hole-pushing equipment generally uses software to control the milling cutter in the above-mentioned background technology. The movement track makes the hole on the surface of the rotor form a shape consistent with the track, but this method has weak control over the milling cutter and its rotating shaft. When the milling cutter rubs against the rotor surface, it is easy to cause the milling cutter to deviate from the preset track due to external force, thus Problems leading to over-drilling
