Abstract
The utility model relates to a testing device for magnetic induction intensity on a fabric surface, which comprises a teslameter, a box body with holes, and a sample plate. By the testing device, the magnitude of the magnetic field on the fabric surface can be accurately and normatively tested, and the testing errors caused by the lack of the necessary testing device and manual operation can be effectively overcome.
Description
Technical field:
The present invention relates to the textile test field, especially the testing arrangement of magnetic induction intensity of textile surfaces is applicable to exploitation, production and the detection of magnetic textiles.
Background technology:
The magnetic textiles is meant by technology such as blending, coatings magnetic material is combined with textile material, makes textiles produce magnetic field.This textiles and human body are regular contacts the medical health care function that can bring into play magnetic field, is that magnetic field acts on the good approach of human body.The magnetic textiles kind of at present magnetic being developed by the mode of blend spinning and post processing is a lot, research and development and the enterprise that produces are also a lot, but about the also not research of test of fabric magnetic field size, production, research and development and detection department all wish to have one to guarantee normalized testing arrangement.
At present, because the magnetic field intensity of textiles is fainter, most of enterprise only is to use the magnetometer of head transformation to detect cloth qualitatively to be had nonmagneticly, can't quantitatively detect the magnetic field size.In the method for testing that other are relevant such as the assay method of rolling bearing residual magnetism, what use is Tesla meter, the axial hall probe of people's hand operated Tesla meter is vertical with the tested surface of rolling bearing downwards, probe keeps the plumbness mobile test on measured surface, but this method is applied directly in the textile field, because textiles is a soft material, especially fluffy fabric, axial probe produces downward pressure in textile surface mobile test meeting to textiles, and the pressure of generation can cause depressed deformation on attenuation of textiles thickness or the thickness direction.The distance dependent on hall probe test value and tested surface system, distance is more little usually, and test value is big more, is difficult to the test value that control causes the attenuation of textiles thickness to the pressure of textiles and then has influence on hall probe during the test of people's hand operated probe.Can not guarantee behind the depressed deformation on the thickness direction that probe axially keeps vertical with textile surface, the angular deflection meeting take place cause bit errors 1-cos θ,, then will produce 0.15% bit errors, thereby influence test result as being 1 ° when the drift angle.The drift angle difference of the variant generation of power that applies in different testers, the different test processs causes the repeated relatively poor of test result.The area of the required test of textiles is big simultaneously, and test data is many, and people's hand operated probe constantly applies active force and very easily damages the sensing unit hall probe in the test process.
Summary of the invention:
The present invention proposes a kind of testing arrangement of magnetic induction intensity of textile surfaces at above-mentioned defective, be used for the magnetic textiles exploitation, produce and detection.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of testing arrangement of magnetic induction intensity of textile surfaces, it is characterized in that it comprises Tesla meter (1), casing with holes (2), the axial hall probe (3) of Tesla meter (1) is inlayed and is fixed in the aperture of casing (2), by variety of way smooth being close under tension-free state of tested fabric is fixed on sample board (4) bottom lower surface, the cross section of described axial hall probe is circular.
Described variety of way can adopt clamping or stickup or other modes, and clamping or stickup or other modes can be by wood clamp or plastic clip or two-sided tape or other lightweight non-magnet_conductible materials.
Described casing (2) adopts non-magnet_conductible material to make, the upper surface of casing is smooth smooth, the length and width of casing (2) should be respectively 2 times of sample length and width at least, the height of casing is slightly larger than the length of axial hall probe (3), centre bit at casing (2) upper surface is equipped with an aperture, the size of aperture and shape and axial hall probe (3) cross section are consistent, at casing (2) upper surface, the center of small holes is used a standardized straight line L parallel with any limit of casing of crayon and a straight line H vertical with straight line L respectively.
Described non-magnet_conductible material is copper aluminium or timber or plastics or other materials.
Described axial hall probe (3) is inlayed in the aperture that is fixed on casing (2) and probe (3) test surfaces is that end face makes progress, retainer shaft is vertical with casing (2) upper surface to the axial direction of hall probe (3), and axially the test surfaces of hall probe (3) is end face and the equal or slightly high 1～2mm of casing (2) upper surface.
Described sample board (4) adopts the lightweight black plastic to make
The shape structure, the smooth and length and width in the bottom of sample board are consistent with sample size, and the both sides height should make things convenient for people's hand operated sample board to move.
At present in this field no standardization quantitative assay through spinning or after the device in the little magnetic field of textile surface of Collator Mode loading permanent-magnet material, the present invention proposes the testing arrangement of quantitative test textile surface Weak magentic-field first, the present invention realizes test by the hall probe test surface upwards is fixed in the casing with holes with moving cloth.When having overcome the test of people's hand operated hall probe, because textiles is a soft material, probe produces pressure in textile surface mobile test meeting and makes its distortion, thereby the angle that makes textiles thickness and hall probe and textile surface is difficult to control, the problem that test result repeatability is relatively poor, simultaneously also overcome people's hand operated hall probe and tested the problem that hall probe very easily damages repeatedly.
Testing arrangement structural framing of the present invention is new, rational in infrastructure, easy operating.
