Abstract
The invention discloses equipment for detecting magnetic flux of a magnetic element. The equipment comprises a supporting frame, an object table which is fixed on the supporting frame, and an electronic scale and an iron block which are arranged exactly below the object table. The object table is prepared by non-magnetic-conductive material. The upper surface and the lower surface of the object table are horizontal planes. The iron block is placed on the electronic scale. The upper surface and the lower surface of the iron block are horizontal planes. A segment of gap is reserved between the upper surface of the iron block and the lower surface of the object table. Advantages are that the magnetic flux of the magnetic element is presented by the numerical value of the electronic scale, and an operator can judge qualification of the magnetic flux of the magnetic element according to the numerical value of the electronic scale only by placing the magnetic element to be detected on the object table so that operation is easy, qualification of the magnetic flux is presented by the numerical value of the electronic scale without interference of external factors, and thus test precision is relatively high.
Description
Technical field
The present invention relates to a kind of checkout equipment, especially relate to a kind of equipment detecting magnetic element magnetic flux.
Background technology
Along with the development of science and technology, magnetic element is more and more applied to every field.In order to ensure the quality of magnetic element, after magnetic element has been produced, need to detect its each important parameter (such as magnetic flux) whether in acceptability limit.
The equipment of existing measurement magnetic flux generally comprises magnetic flux coil (Helmholtz coils) and fluxmeter, and magnetic flux coil is connected with fluxmeter.When testing magnetic flux, opening fluxmeter, magnetic element is first put into magnetic flux coil, then magnetic element to be taken out in magnetic flux coil and away from after magnetic flux coil one segment distance, fluxmeter is tested out the magnetic flux of this magnetic element and exported by its display screen.But there is following problem in the equipment of existing measurement magnetic flux: one, magnetic element needs first to put into magnetic flux coil and then just can complete a testing process away from magnetic flux coil, operation more complicated; Two, magnetic element is far away away from the distance of magnetic flux coil in theory, the data testing accuracy of the magnetic flux of fluxmeter test is higher, but in reality is produced, in order to ensure the efficiency of testing, magnetic element is determined away from the distance of magnetic flux coil, this is apart from not too large, and magnetic element can cause interference to the test of fluxmeter thus, so that the precision of the test data of magnetic flux is not high.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of simple to operate, and the equipment of the higher detection magnetic element magnetic flux of precision.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of equipment detecting magnetic element magnetic flux, comprise bracing frame, be fixed on the objective table on described bracing frame, be positioned at the electronic scale immediately below described objective table and iron block, described objective table is prepared from by non-magnet material, upper surface and the lower surface of described objective table are surface level, described iron block is placed on described electronic scale, upper surface and the lower surface of described iron block are surface level, there is between the upper surface of described iron block and the lower surface of described objective table an intersegmental gap.
The thickness of described objective table is no more than 3mm, and the gap between the upper surface of described iron block and the lower surface of described objective table is no more than 10mm.
Described non-magnet material is stainless steel.
Upper surface and the lower surface of described objective table all polish, and upper surface and the lower surface of described iron block all polish.
Compared with prior art, the invention has the advantages that and to be claimed by unlocking electronic, to after electronic scale zero setting (peeling), standard component (magnetic element that magnetic flux is qualified) is placed on objective table, standard component produces attractive force to iron block, now the reading of electronic scale is negative, according to the range of readings that the now reading of electronic scale and the qualified magnetic element of the margin tolerance determination magnetic flux of magnetic flux to be detected show on electronic scale, the magnetic flux of magnetic element is showed by the reading of electronic scale, operating personnel only need magnetic element to be measured to be placed on objective table, both can judge that whether the magnetic flux of this magnetic element was qualified according to the reading of electronic scale, simple to operate, and the whether qualified reading by electronic scale of magnetic flux shows, the interference of extraneous factor can not be subject to, measuring accuracy is higher,
When the thickness of objective table is no more than 3mm, when the gap between the upper surface of iron block and the lower surface of objective table is no more than 10mm, the attractive force of magnetic element to iron block can be ensured, avoid electronic scale reading too little being difficult to differentiate;
When the upper surface of objective table and lower surface all polish, when the upper surface of iron block and lower surface all polish, improve objective table and iron block horizontality further, improve accuracy of detection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
