Abstract

The present invention relates to a press-fit bolt, and more particularly, to a press-fit bolt having a bolt head formed in a hexagonal shape and having a fixing groove recessed along an outer circumferential surface thereof immediately below the bolt head so that the bolt head is pressed and joined to the base material. To raise
Lt; / RTI >
When the press-fit bolt is inserted into the press-fitting portion of the base material, the press-fit bolt is press-fitted to the base material at the bolt head portion of the press-fit bolt to push the base material into the fixing groove of the press-fit bolt to firmly fix the press- The bolt head of the bolt also enters the inside of the base material and is almost integrated with the base material. In this case, the bolt head is formed into a hexagonal shape, so that the bolt head is pressed into the base material and inserted into the base material, .

Description

Clinching volt

Machine tool

Generally, bolts and nuts are most commonly used for mutual coupling of various mechanical devices and structures.

Among them, the method of pressing the bolts or nuts greatly improves the workability and cost saving compared to the work which had been dependent on the welding. In this case, the indentation bolt or the indentation nut is used.

In the case of the press-fit nut used in the past, after being pressed and inserted into the base material,

And the bolt is inserted into the body to be coupled with the press-fitting nut. Thus, there is a gap between the base material and the body to be bonded, which lowers the adhesion force.

Also, when combined with the bolts and nuts used previously. As shown in FIG. 6, since the bolt head and the nut are formed at both ends after fastening the base material and the body to be fastened, there is a problem that the cosmetic problem and the work process are increased, and the production cost is increased.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a bolt head having a hexagonal head shape and a fixing groove formed in a lower portion of the bolt head along a circumferential surface thereof, So that it is possible to secure the fastening and increase the adhesion force.

The bolt head is formed in a hexagonal shape and the fixing groove is formed in the lower part of the bolt head along the outer circumferential surface to be pressed and joined to the base material so as to firmly tighten the bolt and improve the adhesion force.

As described above, the press-fit bolt according to the present invention has a structure in which the bolt head is formed in a hexagonal shape, and the fixing groove is formed in a recessed shape along the outer circumferential surface just under the head of the bolt and pressed and joined to the base material, And has a much stronger advantage over desorption and torsional loads.

The press-fit bolt according to the present invention is formed with a hexagonal bolt head on its upper portion, and a fixing groove is formed along the outer circumferential surface of the bolt head.

When the press-fit bolt is inserted into the press-fitting portion of the base material and then the press-fit is performed toward the base material from the head of the bolt of the press-fit bolt, the base material is pushed into the fixing groove of the press-fitting bolt to firmly fix the press-fitting bolt.

At this time, the bolt head of the press-fit bolt also enters the inside of the base material and is substantially integrated with the base material. Further, the bolt head is formed into a hexagonal shape and is pressed and inserted into the base material, Which is a much stronger structure.

The to-be-assembled body is fitted to the press-fit bolt pressed and inserted into the base material, and the nut is coupled to the base body.
