Problems solved by technology

[0007] The purpose of the present invention is to overcome the poor repeatability of the measurement due to the different positions of the magnets in the prior art, and it is difficult to compare the magnetic flux values ​​of magnets of different shapes because the position of the geometric center of the magnet cannot be determined, and provides A device for measuring magnetic flux and its measurement method can make each time a magnet is placed in the same position, and when the shape of the magnet is different, its geometric center can be placed in the same position, so that its magnetism pass value for reasonable comparison

Abstract

The invention discloses a magnetic flux measuring device and a measuring method thereof and belongs to the technical field of magnet detection. The magnetic flux measuring device comprises a bottom plate; a bracket is mounted on the bottom plate; a first coil and a second coil which are coaxially arranged are fixed to the upper end and lower end of the bracket respectively; a positioning table fixed on the bottom plate is mounted in the bracket; a positioning assembly used for enabling the geometric center of a magnet to coincide with the axis of the first coil is installed on the positioningtable; the first coil and the second coil are electrically connected with a fluxmeter; and by means of the positioning assembly, the geometric centers of magnets in different shapes can be located atthe same point when the magnets are placed into the device multiple times. With the magnetic flux measuring device and the measuring method thereof adopted, the problems of poor magnetic flux measurement and low accuracy in the prior art can be solved.

Description

technical field [0001] The invention relates to a magnet detection technology, in particular to a magnetic flux measurement device and a measurement method thereof. Background technique [0002] In the conventional manufacturing process of permanent magnet ferrite, it generally needs to go through the following process, powder making (slurry), magnetic field compression molding, sintering, grinding, appearance dimension inspection and magnetic performance testing, etc. After the product is ground by a grinder, it is necessary to conduct a comprehensive inspection and analysis of the product, such as whether the geometric size is within the tolerance range, whether the appearance is qualified, and at the same time, the magnetic performance is inspected and analyzed. In actual large-scale production, before batch sintering of semi-finished blanks, it is necessary to test and compare the magnetic properties after several trial sinterings, and then determine the optimal sinterin...
