[0023] As Figures 1 - 3 shown, a fixing structure of an amorphous alloy iron core includes an upper pressing assembly 1 and a lower pressing assembly 2. The structures of the upper pressing assembly 1 and the lower pressing assembly 2 are the same. The outer edges of the upper pressing assembly 1 and the lower pressing assembly 2 are connected by a connecting rod 3. An amorphous alloy iron core 4 is provided between the upper pressing assembly 1 and the lower pressing assembly 2. Triangular limiting columns 5 are provided in the middle of the upper pressing assembly 1 and the lower pressing assembly 2. The triangular limiting columns 5 are connected to the outer edges of the upper pressing assembly 1 and the lower pressing assembly 2 through L-shaped plates 9. A transverse moving side plate 6 is provided on the vertical surface of the triangular limiting column 5. One end of the transverse moving side plate 6 is connected to a guiding column 7, and the other end of the guiding column 7 extends into the inner cavity of the triangular limiting column 5 and abuts against a conical driving body 8.
[0024] As Figure 2 shown, the top of the triangular limiting column 5 is set as an arc surface 501, and the center of the arc surface 501 is set as a horizontal positioning surface 502, which is convenient for the subsequent insertion of the positioning rod.
[0025] As Figure 2 shown, rubber layers (not shown in the figure) are provided on the outer surfaces of the L-shaped plates 9 and the transverse moving side plates 6. The rubber layers effectively protect the main body of the iron core and avoid situations such as collision damage.
[0026] As shown Figures 2 - 3 in FIG. 3, a bottom plate 10 is connected to the bottom of the triangular limit post 5, and a threaded post 801 is provided at the bottom of the conical drive body 8. The threaded post 801 passes through the bottom plate 10 and is threadedly connected to the bottom plate 10. By rotating the threaded post, the height of the conical drive body can be adjusted.
[0027] As shown Figure 2 in FIG. 4, three groups of positioning holes 5021 are provided on the horizontal positioning surface 502. The three groups of positioning holes 5021 are used to set positioning rods. The positioning rods extend into the triangular limit post without contacting the conical drive body and the guide post and pass through the bottom plate of the triangular limit post and are fixedly connected by nuts. The positioning rods are used to cooperate with external connecting rods to improve the stability after the upper and lower pressing components are connected.
[0028] As shown Figures 2 - 3 in FIG. 5, one end of the guide post 7 located in the inner cavity of the triangular limit post 5 is provided with a guide post inclined surface matching the conical drive body 8. By rotating the conical drive body to increase the height of the conical drive body, the conical drive body contacts the guide post to compress the spring, and then the transverse moving side plate is moved outward. Further, iron cores with different widths can be pressed tightly, improving the stability after the iron core is installed, avoiding shaking, and protecting the iron core body.
[0029] As shown Figures 2 - 3 in FIG. 6, a fixing plate 701 is provided on the guide post 7 located in the inner cavity of the triangular limit post 5. A spring 11 is provided between the fixing plate 701 and the triangular limit post 5. The transverse moving side plate realizes the contact with the vertical surface of the triangular limit post through the restoring force of the spring, avoiding the situation that the transverse moving side plate moves outward and the iron core cannot be installed.
[0030] As shown Figure 3 in FIG. 7, the transverse moving side plate 6 is provided with a side plate inclined surface 601. The sharp angle side of the side plate inclined surface leans against the inner side of the triangular limit post and also covers a rubber layer, further avoiding damage caused by contacting the amorphous alloy iron core and protecting the iron core body.
[0031] The working principle of the present utility model is described as follows: During assembly, the amorphous alloy iron core is inserted. The triangular limit post has no sharp corners, realizing a multi-faceted arc structure, effectively avoiding the risk of damage to the amorphous alloy iron core caused by sharp corners; after insertion, rotate the threaded post to move the transverse moving side plate outward to press the amorphous alloy iron core tightly. The rubber layer can protect the iron core body, and the shaken amplitude of the clamped iron core is smaller, which is beneficial to protecting the iron core body and avoiding damage.

Without departing from the design concept of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention. The technical content claimed by the present invention has been fully recorded in the claims.
