Clamp structure for C-shaped ferrite magnetic core

Abstract

A clamp structure for a C-shaped ferrite magnetic core belongs to the technical field of tooling clamps and comprises a base, a press bar and a pair of clamping pins. A C-shaped cavity penetrating from one end of the base in the length direction to the other end of the base is formed on the upward surface of one side of the base in the use state, a hook plate containing cavity is respectively arranged on end portions of two ends of a downward side of the base in the use state, and the hook plate containing cavity is located in the middle position of the base in the width direction. The press bar is matched with the C-shaped cavity, and a concave cavity is respectively formed at two ends of the press bar. One end of the pair of clamping pins is matched with the hook plate containing cavity, and the other end of the pair of clamping pins is matched with the concave cavities. The clamp structure for the C-shaped ferrite magnetic core has the advantages of being capable of not only ensuring power of the C-shaped ferrite magnetic core and assembling effect during use but also avoiding coil damage during coil winding, and being compact in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the field of fixture technology, and in particular relates to a fixture structure for processing a C-shaped ferrite core . Background technique [0002] The aforementioned C-shaped ferrite cores are not limited to be used in electrical and electronic products, lighting equipment and the like. Usually, it is necessary to grind the C-shaped ferrite core, and the positioning reference plane needs to be determined during the grinding process, and the positioning must also be ensured reliably, otherwise the grinding process effect will be affected, or even scrapped. [0003] Due to the special shape and relatively small size of the C-shaped ferrite core, it is very difficult to locate it in the subsequent grinding process. For this, the industry usually focuses on changing the shape, such as for pressing the C-shaped ferrite core. The mold of the ferrite core blank is modified so that the pressed C-shaped ferrite core blank fo...

Problems solved by technology

[0004] Any one of the above three ways to obtain the positioning reference plane has the following technical problems: as far as the first way is to form a concave platform at the top of the arc , since the cross-section of the C-shaped ferrite core is reduced, it directly affects the power; as for the second method, which is to form a convex platform at the top of the arc, because the volume is enlarged, it is difficult to communicate with the electrons during use. Electrical products or lighting equipment matching; As far as the third method is to pre-grind the positioning reference plane at the top of the arc, not only the lack of the first method exists, but also sharp corners will be formed at the edges of the reference plane. Damage to the coil when winding the coil

It is based on this factor that there is no corresponding technical revelation suitable for effectively holding back the aforementioned C-shaped ferrite core in the current published patents and non-patent literature.
