Abstract
The invention relates to a device for testing polarity of a magnet, comprising a positioning sliding block, wherein the upper end face of the positioning sliding block is embedded with a standard magnet; the positioning sliding block is arranged in an aluminum sleeve and capable of sliding along the axial direction of the sleeve under the action of external force; the sleeve is provided with a reset spring; one end of the spring is pressed against the lower end face of the positioning sliding block while the other end thereof is pressed against the internal cavity bottom of the sleeve; a pressure switch button of a power source indicating lamp is arranged at the lower position of the positioning sliding block positioned in the sleeve internal cavity; a working face for abutting the to-b-tested magnet is formed on the top face of the sleeve; and the working face is parallel to the upper surface of the standard magnet. The device triggers the switch button through the magnetic action relation of the to-be-tested magnet and the standard magnet, then judges the polarity of the testing face of the magnetic by the indicating lamp, so that the testing effect is visualized and distinct.
Description
Technical field
The present invention relates to a kind of test or testing tool, specifically be a kind of proving installation that is used for testing or distinguishing magnet polarity.
Background technology
In the magnetic product industry, magnet for example, finish and reach corresponding performance, must distinguish one from the other generally speaking the N utmost point of magnet and the S utmost point and best mark to some extent, if before magnet being used or be assembled in product, do not go to distinguish that the polarity of knowing magnet will cause many beyond thought situations, for example the magnetic field phase mutual interference between each magnet, reduce magnet suction, even can't bring into play its estimated performance after installing.
Special-shaped or the special magnet for some has just carried out the mark of magnetic pole at present basically before dispatching from the factory, but for the magnet of some shapes commonly used, for example Yuan Xing magnet is not also accomplished clearly to mark; At present follow-up distinguish or test some original straightforward procedures that adopt more, for example concern to finish and distinguish by observing a small magnet of measuring polarity in advance and the gravitation between the magnet to be tested, though such mode can be finished relevant task substantially, but require operating personnel's notice concentrated relatively in identifying, idol has carelessness or absent-mindedly just may misremember; And small magnet also is attached together with the magnet that is identified through regular meeting, with both separation unusual trouble always.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of can conveniently test the device of magnet polarity, and it can feed back to operating personnel with test result intuitively, significantly reduces because the probability of personnel's oversight.
Its technical matters to be solved can be implemented by the following technical programs.
A kind of magnet polarity test device, comprise a location slide block, the upper surface of described positioning sliding block is embedded a benchmark magnet, described positioning sliding block be located in the aluminium matter sleeve and under external force along quill to slidably, also be provided with a back-moving spring in the described sleeve, one end of described back-moving spring is resisted against on the lower surface of described positioning sliding block, and the other end of described back-moving spring is resisted against the inner chamber bottom surface of described sleeve; Be positioned at the pressure switch button that orientation under the positioning sliding block of described barrel bore also is provided with a power light; The end face of described sleeve forms a workplace that is used for reclining magnet to be tested, and described workplace parallels with the upper surface of described benchmark magnet.
As the further improvement of the technical program, described sleeve is cylindrical, and the upper surface of described cylindrical sleeve forms described workplace.
As the further improvement of the technical program, described sleeve is fixed on the mounting base obliquely.
Adopt the magnet polarity test device of technique scheme, concern by the magneticaction between magnet to be tested and the benchmark magnet and touch pilot lamp pressure switch button, and then judge the magnetic pole of magnet test surfaces by external pilot lamp.The test effect of this device is simple and clear.

Embodiment
Magnet polarity test device as shown in Figure 1 to Figure 3, this device is a kind of mechanism that is used for testing magnet polarity, laying a columniform sleeve 2 what mounting base 1 tilted, sleeve 2 is made by alumina based material, cannot be magnetized, the upper surface of sleeve is a workplace 21, sleeve inner hollow, laying one in the inner chamber 22 can be along the magnet locating piece 4 of sleeve wall slip, the top of magnet locating piece 4 is being embedded a benchmark magnet 3 that is used for testing other magnet polarity, these magnet 3 tops are reference field 31, reference field 31 and workplace 21 keeping parallelisms.
Also laying a pressure switch button 6 in barrel bore 22, this shift knob is connecting the pilot lamp 7 of sleeve 2 outsides, and is used for controlling whether bright it is.
Its concrete course of action is as follows:
With the close workplace 21 of the magnet of polarity to be tested, when the magnetic force face polarity of reference field 31 1 sides of the magnet 3 of close magnet magnetic force face and aluminum sleeve the inside is identical, because the principle that the same sex is repelled each other, will promote the magnet 3 in the sleeve and drive magnet locating piece 4 to move downward along barrel, until having touched shift knob 6, this moment, pilot lamp 7 will be bright, if polarity is opposite, then owing to do not have downward acting force or downward gravity deficiency with the touch switch button, pilot lamp can be not bright, and magnet 3 in the sleeve and magnet locating piece 4 can upwards reset under the spring force effect of back-moving spring 5.
The test result of this device directly, accurately.Convenient test has solved existing method of testing test magnet and tested magnet and has inhaled together easily, and test result is less to cerebral irritation, does not allow catchy shortcoming; This device is easy to use, of many uses.
Claims (3)
1. magnet polarity test device, it is characterized in that, comprise a location slide block, the upper surface of described positioning sliding block is embedded a benchmark magnet, described positioning sliding block be located in the aluminium matter sleeve and under external force along quill to slidably, also be provided with a back-moving spring in the described sleeve, an end of described back-moving spring is resisted against on the lower surface of described positioning sliding block, and the other end of described back-moving spring is resisted against the inner chamber bottom surface of described sleeve; Be positioned at the pressure switch button that orientation under the positioning sliding block of described barrel bore also is provided with a power light; The end face of described sleeve forms a workplace that is used for reclining magnet to be tested, and described workplace parallels with the upper surface of described benchmark magnet.
