Abstract
The invention discloses a magnetic field measuring device, which is used for measuring a magnetic field of a miniature multi-pole magnet. The device comprises a Gauss meter and a base, wherein a turntable bracket is arranged on the base; a rotating disc is arranged on one side of the turntable bracket and a magnet frame for fixing the miniature magnet is arranged on the other side of the turntable bracket; the magnet frame is rotationally connected with the rotating disc through a bearing; a bracket for fixing the Gauss meter is arranged on the base close to one side of the magnet frame; the miniature magnet comprises at least test points; the rotating center of the rotating disc is consistent with the centre of a circumcircle of each test point; and a probe of the Gauss meter is positioned on a circular path of the circumcircle. The position of each test point of the miniature multi-pole magnet can be accurately aligned with the probe of the Gauss meter by rotating the rotating disc only, the device is easy to operate, convenient to use and high in accuracy and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of magnetic field measuring device, relate in particular to a kind of magnetic field measuring device of miniature many pole magnet.
Background technology
In the prior art, the instrument of measuring magnet surface magnetic field is generally gaussmeter, gaussmeter is a kind of relatively accurate surveying instrument, especially the Hall plate of probe segment, it is high to Magnetic susceptibility, the magnetic field intensity of each position in can measurement plane magnetic field, and show by gauging table.Magnetic field for the miniature a plurality of magnetic poles of distribution, want to measure wherein each regional magnetic field intensity, at present commonly used is manually method, measure with each region point that gaussmeter is aimed on the magnet, because magnet itself is just very small, locate very difficult, therefore, the accuracy rate of not only measuring is low, and measurement data is unreliable, and work efficiency also reduces.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of magnetic field measuring device that can be used for measuring miniature many pole magnet.
Purpose of the present invention will be achieved by the following technical programs:
A kind of magnetic field measuring device, be used for measuring the magnetic field of miniature many pole magnet, comprise gaussmeter, also comprise a base, described base is provided with a support for rotary disc, described support for rotary disc one side is provided with rotating disc, and opposite side is provided with the magnet frame for fixing miniature magnet, passes through the bearing connection of rotating between described magnet frame and the rotating disc; Base near described magnet frame one side is provided with for the support of fixing described gaussmeter; Described miniature magnet comprises at least 2 test points, and the rotation center of described rotating disc is consistent with the center of circle of the circumscribed circle of described each test point, and the probe of described gaussmeter is positioned on the circular path of described circumscribed circle.
Further, above-mentioned magnetic field measuring device, wherein: described rotating disc is connected with an electric transmission machanism.
Further, above-mentioned magnetic field measuring device, wherein: described rotating disc is connected with a cogwheel gearing.
The present invention only need be by rotating rotating disc, can make the position of the test point of miniature many pole magnet accurately aim at the probe of gaussmeter, and simple to operate, easy to use, accuracy rate is high, has improved work efficiency.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
