Method for installing magnetic steel in circular hole

Abstract

The invention relates to a method for installing magnetic steel in a circular hole. The method comprises the steps of loading a yoke body into a fixture base, installing auxiliary magnetic steel by anauxiliary magnetic steel installing fixture and an auxiliary magnetic steel pushing fixture, loading a magnetic steel loaded positioning block into the yoke body, loading simulated magnetic steel into the yoke body, replacing a first piece of the simulated magnetic steel with a first piece of magnetic steel, compressing by a pressing plate structure, replacing a second piece of the simulated magnetic steel adjacent to the first piece of magnetic steel with a second piece of magnetic steel, pushing the second piece of magnetic steel to be next to the first piece of magnetic steel through rotating the compressing device, and compressing the first piece of magnetic steel and the second piece of magnetic steel by the pressing plate structure; installing the left magnetic steel according to the replacement method of the second piece of magnetic steel; fastening the yoke body and the magnetic steel loaded positioning block by using a magnetic steel fastening device, taking the yoke body outfrom the fixture base, performing position fixation, and completing the installation. The magnetic steel is installed by adopting the special assembly fixtures and the specific technological method,thereby being excellently controlling the assembling process of the magnetic steel, meeting assembly requirements of the magnetic steel, having high positioning accuracy, being simple and practical inassembly technological process, capable of installing in place in one time, and reducing the assembly rework rate.

Description

technical field [0001] The invention belongs to the technical field of mechanical assembly, and in particular relates to a method for installing magnetic steel in a circular hole. Background technique [0002] In the actual production process, we often encounter such figure 2 A part of the type of motor yoke shown, where a hole such as image 3 The auxiliary magnetic steel shown, and install multiple pieces such as Figure 4 magnets shown, and finally formed as figure 1 Magnet mounting assembly shown. When combined, since the material of the magnetic steel and auxiliary magnetic steel is NdFeB371 / 138 soft magnetic alloy, it has a large magnetic force after magnetization, and the material of the motor yoke is iron cobalt vanadium soft magnetic alloy 1J22, which itself is also It has a certain degree of magnetism. When assembling, due to the magnetic attraction or mutual repulsion between the various parts, it brings great difficulties to the assembly. If the parts cannot...

When combined, since the material of the magnetic steel and auxiliary magnetic steel is NdFeB371 / 138 soft magnetic alloy, it has a large magnetic force after magnetization, and the material of the motor yoke is iron cobalt vanadium soft magnetic alloy 1J22, which itself is also It has a certain degree of magnetism. When assembling, due to the magnetic attraction or mutual repulsion between the various parts, it brings great difficulties to the assembly. If the parts cannot be placed and fixed according to the assembled position at one time, it will cause rework. Difficulties and scrapping of magnetic steel, resulting in a lot of waste
