Abstract
The utility model relates to a cross-shaped magnetic flux testing device comprising a cross-shaped iron core (2). The cross-shaped iron core (2) is formed by crossing and connecting a first iron core frame body (9) and a second iron core frame body (10). The cross-shaped iron core (2) is wounded with a copper coil (3) and is fixed and moulded in a sleeve (5) through epoxy resin adhesive (4). The sleeve (5) is fixedly arranged on a base (1) through a sleeve housing (6). The upper end surface at one end of the base (1) is provided with a wiring terminal (7). According to the cross-shaped magnetic flux testing device, the iron core arrangement structure is improved by changing an original single frame iron core into a crossed double-frame cross-shaped iron core, so that the cross-shaped magnetic flux testing device is capable of accurately testing the magnetic flux of a magnetic block and the testing precision is high; and the magnetic block is performed magnetic-flux measurement after each step in the production process, so that the magnetic flux loss of the magnetic block can be traced and the process is adjusted based on actual conditions.

beneficial effect
The utility model relates to a kind of cruciform magnetic flux proving installation, improved iron core arranging structure, by the single frame body iron core in past, be transformed into the cruciform core of two frameworks of right-angled intersection, can accurately test the magnetic flux of magnetic patch, testing precision is high, magnetic patch carries out magnetic-flux measurement after links in production technology, can follow the trail of magnetic patch flux loss amount, according to actual conditions, carries out technique adjustment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that cruciform core of the present utility model is arranged in the structural representation in sleeve.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1-2, the utility model relates to a kind of cruciform magnetic flux proving installation, comprise cruciform core 2, described cruciform core 2 is connected to form by the first iron core framework 9 and the second iron core framework 10 right-angled intersections, on described cruciform core 2, be wound around copper coil 3, described cruciform core 2 is fixed-type in sleeve 5 by epoxide-resin glue 4, described sleeve 5 is fixed on base 1 by sleeve shell 6, described base 1 upper surface is provided with terminals 7 by one end, the parallel edge 11 in described described the first iron core framework 9 and the both sides of the second iron core framework 10 is wound around copper coil 3, described copper coil 3 is connected with terminals 7 by cable 8, described sleeve shell 6 upper surfaces are provided with product test mouth 12, and described product test mouth 12 is positioned at cruciform core 2 tops, described terminals 7 are connected with fluxmeter.
Embodiment 1
The step that employing the utility model carries out magnetic flux test is as follows: the signal input part by the signal output part of magnetic flux head coil with fluxmeter connects, the position of platform of regulating winding inside makes the requirement that the height of platform is appropriate to measure (suitable height for by the putting into after coil of sample, the center line of sample is just in time aimed at coil Guan Chakong center).Magnetic patch is placed on to test zone, clicks the return-to-zero button of fluxmeter, make the data of fluxmeter be shown as zero, then take magnet away, the magnetic patch magnetic flux that the data that now fluxmeter shows are this magnet.
