Description

An assembly tool for special-shaped eccentric head combination bolts

technical field

The utility model belongs to the technical field of machinery, and in particular relates to an assembly tool for a special-shaped eccentric head combination bolt.

Background technique

The special-shaped eccentric head combination bolt includes two parts: the washer and the bolt; among them, the head of the bolt is a special-shaped eccentric head. During the assembly process, when the vertical pressure is applied for assembly, due to the eccentricity of the bolt head, a lateral force will be generated to affect the assembly. , the generation of the lateral component force will lead to uneven stress on the special-shaped eccentric head combination bolt, which will cause metal shedding at the contact between the washer and the bolt, which is not allowed to happen in the assembly appearance requirements. Therefore, it is difficult to assemble It has become the bottleneck of the production of this combined part.

Utility model content

The purpose of the utility model is to overcome the aforementioned difficulties and provide an assembly tool for special-shaped eccentric head combination bolts with simple structure, easy operation and remarkable effect.

The utility model relates to an assembly tool for a special-shaped eccentric head combination bolt, which includes an assembly upper seat and an installation lower seat. It refers to the body sleeve that matches the washer of the special-shaped eccentric head combination bolt and the shape below the bolt head.

Compared with the prior art, the utility model has obvious beneficial effects. It can be seen from the above technical scheme that the utility model can make the head of the bolt become a conventional head-shaped bolt during assembly through the setting of the assembly upper seat, and the force passes through the axis. Effectively eliminate the lateral component force and prevent metal falling off to achieve the effect of assembly; through the setting of the mounting base, the washer used to fix the special-shaped eccentric head combination bolt can prevent the washer from moving during assembly; the tooling can not only make assembly convenient , It can also ensure that the appearance of the combined parts is not damaged.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a special-shaped eccentric head combination bolt, as shown in Fig. 2-3, the assembly tooling of the special-shaped eccentric head combination bolt of the present utility model, comprises assembly upper seat 1 and installation lower seat 2, and described assembly upper seat refers to and special-shaped eccentric head The head cover that the shape of the bolt head 3 of the combination bolt matches, and the described installation base refers to the body cover that matches the shape of the washer 4 of the special-shaped eccentric head combination bolt and the shape below the bolt head 3.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any modifications made to the above embodiments according to the technical essence of the present utility model do not deviate from the content of the technical solution of the present utility model. Any simple modifications, equivalent changes and modifications still belong to the scope of the technical solution of the present utility model.
