Problems solved by technology

Bolts are commonly used to connect this type of hood. However, when bolts are used to connect the rear of the hood, it is difficult for the operator to confirm the bolt holes with the naked eye, and assembly must be done intuitively.
In this way, the bolts will be worn during the assembly process, which will delay the assembly time and reduce productivity.

Embodiment Construction

[0033] Next, the present invention will be described in detail with reference to the drawings. Such as figure 1 As shown, the present invention consists of a bolt 10 and a bushing 20 surrounding the bolt 10. The bolt 10 is composed of a polygonal head 11, a circular washer 12 located on the underside of the head 11, an upper body part 13 and a lower body part 16 connected from the washer 12 to the bottom. A blocking portion 14a having a radius larger than that of the upper body portion 13 and the lower body portion 16 is formed between the upper body portion 13 and the lower body portion 16. The upper side of the blocking portion 14a is perpendicular to the bolt 10, and the lower side has a slope surface 14a-1 inclined downward toward the central axis of the bolt 10. Threads 15 are formed on the lower body portion 16 and are combined with nuts embedded in the base material 30 . The screw thread 15 is formed at the central portion of the lower body portion 16 and is not conn...

Abstract

The invention relates to an insert bolt and a bushing manufacturing method using a bushing. In order to assemble the bolts stably, the bushing is clamped in the groove connected by the base material bolt, and the embedded bushing can play a role in guiding the bolt connection. The role of position, thus referring to accuracy and stability. In addition, the bushing can be fixed to the base material by the outer protrusions provided on the outer side of the bushing, and the bolts can be prevented from coming out of the bushing by the inner protrusions provided on the inner side of the bushing.

Description

technical field [0001] The present invention relates to the manufacturing method of the insert bolts and the bushing using the bushing, and further relates to a method of fixing the bushing on the base material by using the outer protrusions arranged on the outer side of the bushing, and using the outer protrusions arranged on the inner side of the bushing to fix the bushing The inner protrusion on the upper part prevents the bolt from coming out of the bushing, and the manufacturing method of making a circular bushing on a plate-shaped metal material by using a plurality of forming fixtures. Background technique [0002] Generally speaking, the hood is an important device to protect the engine in a vehicle, it can block the external pressure acting on the engine, prevent the engine from deforming or malfunctioning, etc. Bolts are commonly used for this type of hood connection, but when bolts are used to connect the rear part of the hood, it is difficult for workers to confi...
