Description
Technical field
The utility model relates to magnetic patch technical field of measurement and test, particularly relates to a kind of miniature magnetic flux proving installation.
Background technology
The Design and manufacture trend of digital cell phone camera is to miniaturization, how can test out the vector of magnet magnetic flux in each technical matters accurately, situation according to the actual loss of magnetic flux adjusts technique, improve the magnetic behavior of magnetic property product with this, become an instant problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of miniature magnetic flux proving installation, can test out the vector of magnet magnetic flux in each technical matters accurately.
The utility model solves the technical scheme that its technical matters adopts: provide a kind of miniature magnetic flux proving installation, comprise base and pick-up unit, described pick-up unit comprises two iron cores and rheostat, described two iron cores are wound with four groups of coils, described iron core is arranged on iron core location-plate, and described rheostat is arranged on base; Described coil and rheostat are connected with connecting line; Described connecting line is connected with the both positive and negative polarity terminals on base.
Described iron core also overlaps outward shell, and the top of described shell is provided with location-plate.
The end face of described iron core is fixed on location-plate.
Described base bottom is provided with four rubber feets.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model by being wound around 4 groups of coils on 2 iron cores, can measure accurately W1.0*1.2*0.35 microminiature product, thus reach that very small product also can be accurate, uncertain measure numerical value, improve measuring accuracy.

Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment of the present utility model relates to a kind of miniature magnetic flux proving installation, as shown in Figure 1, comprise base 1 and pick-up unit, described pick-up unit comprises two iron cores 2 and rheostat 3, described two iron cores 2 are wound with four groups of coils 4, described iron core 2 is arranged on iron core location-plate 5, and described rheostat 3 is arranged on base 1; Described coil 4 and rheostat 3 are connected with connecting line 6; Described connecting line 6 is connected with the both positive and negative polarity terminals 7 on base 1.The outer also cover of described iron core 2 has shell 8, and the top of described shell 8 is provided with location-plate 9.The end face of described iron core 2 is fixed on location-plate 9.
As shown in Figure 2, the bottom of base is provided with 4 rubber feets, and position, hole 17 is fixed with screw.Mounting anode and cathode terminals on base.
As shown in Figure 1, pick-up unit comprises 2 iron cores and slide rheostat, 2 iron cores is wound around 4 groups of coils (see Fig. 3), and what can reach that very small product also can be accurate, uncertain measures numerical value.Thereafter iron core is arranged on iron core location-plate.Slide rheostat is laid in the position, hole 14 on base in fig. 2, and is fixed by gluing.Coil and slide rheostat are connected in series connecting line, and this connecting line is connected with both positive and negative polarity terminals 8 through the position, hole 16 of base in Fig. 2.Shell 2 is arranged on base 1, and with fixing on the position, hole 15 of screw base in fig. 2.Location-plate 3 is arranged on shell 2, and the end face of iron core 5 is fixed on (see Fig. 4) on location-plate 3, can be fixed by screw through the pilot hole 19 on location-plate 3 in Fig. 4.
It is as follows that the utility model carries out magnetic flux testing procedure: connected by the signal input part of magnetic flux head coil signal output both positive and negative polarity terminals with fluxmeter.Magnetic patch is placed on test zone (region of Fig. 5 arrow points), presses the zero reset button of fluxmeter, make the numerical value display zero of fluxmeter, then taken away by magnet, the data of fluxmeter display this moment should be magnetic patch magnetic flux.The difference such as magnetic patch specification, performance regulates the corresponding resistance of this magnetic patch to measure by slide rheostat.
Be not difficult to find, the utility model by being wound around 4 groups of coils on 2 iron cores, can be measured W1.0*1.2*0.35 microminiature product accurately, thus reach that very small product also can be accurate, uncertain measure numerical value, improve measuring accuracy.
