[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1 to 2 Combination Figure 4 As shown, a ring-shaped Helbeck wireless magnetizing assembly fixture includes a base plate 10 and a cover plate 20. The base plate 10 includes a bottom plate 11 and an upper plate 12. The bottom plate 11 is provided with a plurality of positioning posts 111. The upper plate 12 is provided with a plurality of first positioning holes 120 and a first positioning groove 100 that penetrates its body vertically. The first positioning holes 120 are fitted onto the positioning posts 111 so that the upper plate 12 abuts against the bottom plate 11. The first positioning groove 100 and the upper end face of the bottom plate 11 are used to position a magnetic ring 1A. The cover plate 20 is provided with a plurality of second positioning holes 201 and a second positioning groove 200 for positioning an iron ring 1B is provided on one side wall. The second positioning holes 201 are fitted onto the positioning posts 111 so that the iron ring 1B in the second positioning groove 200 abuts against the magnetic ring 1A in the first positioning groove 100.

[0026] More specifically, four positioning posts 111 are provided on the substrate 11, and the four positioning posts 111 are respectively located at the four corners of the bottom plate 11. Correspondingly, the four corners of the upper plate 12 are respectively provided with first positioning holes 120, and the four corners of the cover plate 20 are respectively provided with second positioning holes 201. Through the cooperation of the positioning holes and positioning posts, the precise alignment between the upper plate 12 and the bottom plate 11, and between the cover plate 20 and the substrate 10 can be achieved.

[0027] In this invention, the upper plate 12 is positioned on the bottom plate 11. A magnetic ring 1A is placed in the first positioning groove 100 formed between the two for positioning, and an iron ring 1B is placed in the second positioning groove 200 on the cover plate 20 for positioning (glue is applied to the positioned iron ring 1B). The cover plate 20 is then inverted onto the upper plate 12, so that the iron ring 1B abuts (and is bonded) to the magnetic ring 1A to form the product ring-shaped Heilbeck wireless magnetizing assembly. After the product is assembled, the cover plate 20 is removed from the positioning post 111 and the base plate 10. Since the iron ring 1B is bonded to the magnetic ring 1A, the position of the iron ring 1B will not be offset. After moving the upper plate 12 away from the positioning post 111 and the bottom plate 11, only the product is left on the upper surface of the bottom plate 11, which can be easily removed. In another embodiment, in order to ensure that the product is not lifted when the upper plate 12 is separated from the positioning post 111 and the bottom plate 11, the bottom plate 11 can be made of a magnetic material, such as stainless iron. The magnetic ring 1A can be attracted to the bottom plate 11 to ensure that the product will not be lifted and detached from the bottom plate 11. Since the magnetic ring 1A and the iron ring 1B are already bonded, even if the bottom plate 11 is made of a magnetic material, the product can be detached from the bottom plate 111 by translating or rotating the product on the upper surface of the bottom plate 11.

[0028] This invention positions the magnetic ring 1A using the first positioning groove 100 on the upper plate 12 and the bottom plate 11, and positions the iron ring 1B using the second positioning groove 200 on the cover plate 20. The cover plate 20 and the base plate 10 are positioned by the positioning post 111 to achieve product assembly, ensuring the precise alignment of the components (magnetic ring 1A and iron ring 1B) in the product and ensuring the assembly accuracy of the product. Moreover, the upper plate 12 is connected to the bottom plate 11 through the positioning post 111, which makes it convenient to replace the upper plate 12 with different specifications to achieve the first positioning groove 100 of different specifications on the base plate 10, and to match the first positioning groove 100 with the second positioning groove 200 of different specifications on different cover plates 20, so as to achieve the assembly of products of different specifications and improve the applicability of the assembly fixture.

[0029] Preferably, multiple insertion holes (not shown) can be provided on the base plate 11, preferably blind holes, and the positioning pins 111 are inserted into the insertion holes. That is, the positioning pins 111 are detachably set on the base plate 11, so that the positioning pins 111 can be used in a reasonable way. For example, in another embodiment, it is not necessary to use four positioning pins 111, but three positioning pins 111 can be inserted into the insertion holes, or two positioning pins 111 can be inserted into the insertion holes arranged diagonally on the base plate 11.

[0030] The upper surface of the base plate 11 has relief grooves 112 on both sides, through which fingers or embedded tools can be easily inserted to separate the upper plate 12 from the base plate 11.

[0031] Combination Figure 3As shown, a mounting hole 202 is provided on the side wall of the cover plate 20 away from the second positioning groove 200. An adsorption magnet 30 is detachably provided in the mounting hole 202. During the process of fastening the cover plate 20 and the substrate 10, since the cover plate 20 is in an inverted state, the second positioning groove 200 is located at the lower end of the cover plate 20. In order to prevent the iron ring 1B located in the second positioning groove 200 from falling off during the inverted closing process, an adsorption magnet 30 is provided on the other side of the cover plate 20 to adsorb the iron ring 1B. After the cover plate 20 and the substrate 10 are closed, the adsorption magnet 30 can be removed from the mounting hole 202 to release the iron ring 1B.

[0032] To facilitate the removal of the magnet 30 from the mounting hole 202, when the magnet 30 is placed in the mounting hole 202, the magnet 30 protrudes from the cover plate 20, making it easy for the operator to hold or use a tool to clamp the protruding part of the magnet 30 and remove it.

[0033] To ensure the stability of the magnet 30 within the mounting hole 202, an elastic support block 203 is provided within the mounting hole 202. The elastic support block 203 can be adhered to the cover plate 20. The magnet 30 is a ring magnet, which is fitted onto the elastic support block 203 and makes an interference fit with it. With the above arrangement, the magnet 30 can be stably installed and easily removed. Furthermore, the elastic support block 203 has a cylindrical structure, and the magnet 30 has a ring structure.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
