A kind of rotor punching equipment that can avoid excessive opening for three-phase motor processing

Abstract

The invention discloses a rotor pushing device for three-phase motor processing that can avoid excessive opening, and relates to the technical field of three-phase motor processing, in particular to a processing frame and a hole-opening assembly. The top of the processing frame is equipped with an adjusting motor, Electric lifting rods are arranged on both sides of the bottom surface of the transmission disc, the opening assembly is fixed on the bottom of the electric lifting rod, and a rotor body is placed on the bottom of the processing frame. The three-phase motor processing uses a rotor-pushing device that can avoid excessive hole opening, and synchronously limits the movement trajectory of the milling cutter head from the physical level, so as to improve the stability of the milling cutter head when it moves, and avoid excessive opening due to jitter. , and further measure the distance between the milling cutter head and the bottom of the rotor body in real time during the opening, so as to accurately control the depth of the opening, and then further by replacing the first shaping piece and the second shaping piece of the teeth edge of the shaping piece with different shapes The two shaped parts can use milling cutter heads with different action trajectories to adapt to different opening 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 for three-phase motor processing, which can avoid excessive opening. Background technique [0002] The rotor is an important part of the three-phase motor. The rotor of the three-phase motor is generally composed of a coiled iron core, a slip ring, a fan blade, etc. The rotor surface often has evenly distributed holes for winding, and these holes are usually It is formed by rotating the milling cutter and pushing down on the surface of the rotor to make a hole. [0003] The existing punching equipment generally controls the movement trace of the milling cutter through software 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 rotating shaft. During friction, it is easy to cause the milling cutter to deviate from the preset trajecto...

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
