Background Art

[0002] Nanocrystalline magnetic cores have extremely high magnetic permeability, high saturation magnetic induction intensity, low coercivity, and low loss, and are suitable for occasions such as filter common mode inductors, high-frequency transformers, frequency converters, and current transformers. In the new energy field, such as solar inverters and wind power generation, they have also been widely used. After the production and processing of nanocrystalline magnetic cores, it is necessary to detect the softness and hardness of the nanocrystalline magnetic cores to facilitate smooth grasping and installation during the subsequent processes of core curing and assembly.

[0003] However, currently, the detection is mainly carried out by manually setting corresponding weights on the nanocrystalline magnetic cores. However, manual detection is prone to errors and low detection efficiency. Therefore, it is very necessary to develop a detection tool for the curing effect softness and hardness of magnetic cores that can quickly detect. Summary of the Utility Model

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a detection tool for the curing effect softness and hardness of special-shaped nanocrystalline magnetic cores, which can efficiently and conveniently detect the curing effect softness and hardness of magnetic cores.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

The upper slider and the lower slider are both slidably matched with the sliding slot, and the lower slider is closely attached to the lower part of the upper slider. Both sliders are fixedly connected to the column through tightening bolts.

[0008] Further, a difference scale is provided at the end of the upper slider close to the product placement area. The difference scale is an L-shaped structure composed of a horizontal scale one and a vertical scale, and a set of scales is provided on the vertical scale.

[0009] Further, a horizontal scale two is provided at the end of the lower slider close to the product placement area. Before measurement, the end of the horizontal scale two is located in the L-shaped groove formed by the horizontal scale one and the vertical scale.

[0010] Furthermore, the sum of the thickness of the second horizontal scale and the thickness of the vertical scale is equal to the thickness of the first horizontal scale.

[0011] Furthermore, a set of adjustment holes are provided on the sliding card slot, and through holes matching the size of the adjustment holes are provided on both the upper slider and the lower slider.

[0012] Furthermore, a height scale is provided on the column, and the height scale is located on the left side of the sliding card slot.

[0013] Furthermore, a strip-shaped protrusion is provided on the upper surface of the base along its length direction, and the product placement area and the column are respectively located on both sides of the strip-shaped protrusion.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but the scope protected by the present utility model is not limited to the described scope.

[0023] As Figure 1-2 shown, a detection tool for the softness and hardness of the curing effect of a special-shaped nanocrystalline magnetic core includes a base 2. Along the length direction of the upper surface of the base 2, a strip-shaped protrusion 14 is provided. One side of the strip-shaped protrusion 14 is a product 1 placement area, and on the other side, there is a column 3. A detection component for detecting the softness and hardness of the product 1 is provided on the column 3. Among them, the detection component slides up and down along the column 3 and is fixedly connected to the column 3 after its position is determined.

[0024] In the present utility model, the detection component includes an upper slider 5 and a lower slider 6. Along the height direction of the surface of the column 3, a sliding slot 9 is opened. The sliding slot 9 is of a U-shaped structure. Both the upper slider 5 and the lower slider 6 can move up and down along the sliding slot 9 to facilitate the detection of the softness and hardness of different nanocrystalline magnetic cores. After the positions of the two sliders are determined, they are fixedly connected through a tightening bolt 4.

[0025] In this embodiment, a set of adjustment holes are opened on the sliding slot 9, and through holes matching the sizes of the adjustment holes are opened on both the upper slider 5 and the lower slider 6. After the positions of the two sliders are determined, the tightening bolt 4 passes through the through holes of the two sliders and the corresponding adjustment holes to achieve fixation.

[0026] At the end of the upper slider 5 close to the product 1 placement area, a difference scale 8 is provided. The difference scale 8 is an L-shaped structure composed of a horizontal scale 10 and a vertical scale 11. Among them, a scale 12 is provided on the upper surface of the vertical scale 11.

[0027] At the end of the lower slider 6 close to the product 1 placement area, a horizontal scale 13 is provided. Before measurement, the end of the horizontal scale 13 is located in the L-shaped groove formed by the horizontal scale 10 and the vertical scale 11, so that the length of the vertical scale 11 is the same as the width of the horizontal scale 13.

[0028] In addition, the sum of the thickness of the horizontal scale 13 and the thickness of the vertical scale 11 is equal to the thickness of the horizontal scale 10. Embodiment 1

[0029] The specific process of detecting the softness and hardness of the curing effect of a special-shaped nanocrystalline magnetic core by using the height scale 7 of the tooling of the present utility model is as follows:

[0030] First, place Product 1 in the placement area of Product 1. Align the second horizontal scale 13 of the lower slider 6 with a scale on the height scale 7, which is denoted as Scale One. Then, place the corresponding weights on the upper surface of Product 1. At this time, the upper slider 5 and the lower slider 6 move downward rapidly as a whole until they reach the upper surface of Product 1. At this time, the second horizontal scale 13 of the lower slider 6 also aligns with the scale on the height scale 7, which is denoted as Scale Two. The distance between the two scales is the height dimension variable of the softness and hardness of the magnetic core. Finally, by comparing with the standard, the softness and hardness of Product 1 can be detected. Embodiment 2

[0031] The specific process of detecting the softness and hardness of the curing effect of the special-shaped nanocrystalline magnetic core by using the differential scale 8 of the tooling of the present utility model is as follows:

[0032] First, place Product 1 in the placement area of Product 1. Align the first horizontal scale 10 of the upper slider 5 with a scale on the height scale 7, and fix the upper slider 5. Then, place the corresponding weights on the upper surface of Product 1. At this time, the lower slider 6 moves downward rapidly until the end of the second horizontal scale 13 abuts against the upper surface of Product 1. The height by which the second horizontal scale 13 of the lower slider 6 descends is denoted as the height dimension variable of the softness and hardness of the magnetic core. Finally, by comparing with the standard, the softness and hardness of Product 1 can be detected.

[0033] Using the differential scale 8 of the tooling of the present utility model to detect the softness and hardness of the curing effect of the special-shaped nanocrystalline magnetic core is a preferred embodiment of the present utility model, which is applicable to the situation where the height dimension variable of the softness and hardness of the magnetic core is small.
