Problems solved by technology

There are two ways to place the magnets of the motor rotor: built-in and surface-mounted. Both methods require a size inspection of the magnets. If the size of the magnet is too large, it will not be able to be installed or the magnet will be scrapped directly. If the size of the magnet is too small, it will be installed It will be photographed that the gap between the magnet and the punch is too large
Therefore, it is necessary to check the size of the magnetic steel, but there is no special measuring tool for checking the magnetic steel on the market. If you use ordinary measuring tools to check the magnetic steel, you cannot get accurate values.

Embodiment Construction

[0010] Such as figure 1 , figure 2 As shown, a magnetic steel inspection tool includes a body 10, and a through groove 11 is opened on the body 10, and the cross section of the groove 11 is the same as that of the stamping groove. By simulating the groove shape of the punching sheet, the groove 11 is processed by the wire cutting process. The magnet steel A to be inspected is used as the sub-block, and the inspection tool is used as the mother block. The magnet steel A to be inspected can pass through the groove on the body smoothly and If there is no obvious gap, the size of the magnetic steel A to be inspected is qualified. If the magnet steel A to be inspected cannot pass through the groove on the body smoothly, it means that the size of the magnet steel A to be inspected is too large and unqualified; if the magnet steel A to be inspected can pass through the groove on the body smoothly but the gap is too large, it means The size of the magnetic steel A to be inspected i...

Abstract

The invention aims to provide a detection tool for checking the size of magnetic steel. The detection tool comprises a body,wherein a V notch is formed on the body,and the cross section of the V notchis the same as that of the punching groove. Through the simulation of the punching groove type,the magnetic steel A to be detected is a sub-block,and the detection tool is a mother block,and the magnetic steel A to be detected can pass through the V notch on the body and has no obvious clearance,and the size of the magnetic steel A to be detected is qualified.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a magnetic steel inspection tool. Background technique [0002] The rotor core of the permanent magnet motor is inlaid with magnetic steel. The cross-sectional view of the magnetic steel is as follows figure 1 As shown in the figure, during the assembly process of the magnetic steel, the magnetic steel with different polarities needs to be inserted into the punching slots on the corresponding rotor surface. There are two ways to place the magnets of the motor rotor: built-in and surface-mounted. Both methods require a size inspection of the magnets. If the size of the magnet is too large, it will not be able to be installed or the magnet will be scrapped directly. If the size of the magnet is too small, it will be installed It will be photographed that the gap between the magnet and the punch is too large. Therefore, it is necessary to check the size of the magnet, ...
