The method of installing magnetic steel in the round hole

Abstract

The method of installing the magnet in the round hole includes the following installation steps: install the yoke body into the fixture base, install the auxiliary magnet with the auxiliary magnet installation jig and push the auxiliary magnet jig, and install the magnet positioning block into the In the yoke body, put the simulated magnetic steel into the yoke body, replace the first simulated magnetic steel with the first magnetic steel and press it with the pressure plate structure, and replace the one next to the first magnetic steel with the second magnetic steel For the second piece of simulated magnet, push the second piece of magnet close to the first piece of magnet by rotating the pressing device, and press it tightly with the pressure plate structure; install the remaining magnet according to the replacement method of the second piece of magnet above; Fasten the yoke body and the magnetic steel positioning block with the fastening magnetic steel device, then take it out from the fixture base and perform position curing to complete the installation. The invention adopts a special assembly fixture and installs the magnetic steel with a specific process method, can well control the assembly process of the magnetic steel, meets the assembly requirements of the magnetic steel, has high positioning accuracy, simple and practical assembly process, and can be installed in place at one time, reducing 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 Auxiliary magnetic steel as 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
