Abstract

Bolt structure effective for reduce mounting space is provided to easily perform a coupling work of a bolt and a nut by giving improved bolt structure. A bolt structure effective for reduce mounting a space includes a tool gripping section(10) formed on the end part(20) of a road part. The bottom surface of the tool gripping section(10) is installed along the whole diameter. The tool gripping section(10) is integrated with the bolt. The guide part helps the bolt to be fixed. The tool gripping section(10) is deposited to an end part of a road part. The tool gripping section(10) is constructed in such a manner that the width of the tool gripping section(10) does not excess the semi-diameter of the road part. A nut is coupled with a bolt after a tool such as a spanner grips the tool gripping section(10) so as to prevent the movement of the bolt.

Description

공간 절약형 보울트 구조{Bolt structure effective for sparing mounting space} Bolt structure effective for sparing mounting space

본 발명은 공간 절약형 볼트 구조에 관한 것이다. 더욱 구체적으로는 볼트의 끝단에 공구파지부를 두어 볼트와 너트의 체결 작업을 간편히 하고, 공간이 협소한 곳에서도 원활하게 체결 작업을 수행할 수 있도록 개량된 볼트 구조에 관한 것이다.The present invention relates to a space saving bolt structure. More particularly, the present invention relates to a bolt structure that has a tool gripping portion at the end of the bolt to simplify the fastening operation of the bolt and nut, and to perform the fastening operation smoothly even in a narrow space.

도 1에 도시한 것과 같이 자동차 조립 공정등에 있어 볼트(B')와 너트(N')의 체결 작업은 먼저 볼트(B')를 체결구조물(1')에 삽입한 후, 너트(N')를 가조립하고, 스패너와 같은 파지 공구로 볼트(B')의 헤드부 또는 나사부를 잡고 너트에 힘을 주어 볼트에 나사 결합하는 방식을 취하고 있다. 이때, 파지 공구로 볼트를 잡지 않으면 너트의 회전이 볼트의 회전과 요동을 수반하여 피치각이 일치하지 않고 토크가 어긋나서 체결 작업이 완전하게 수행될 수 없으므로 볼트(B')의 고정은 필수적인 것이라고 할 수 있다. 그런데, 파지공구로 볼트(B')를 고정하기 위한 작업 공간이 부족한 경우는 너트(N')를 체결구조물(1')에 가용접한 상태에서 볼트(B')를 회전시켜 두 부재를 결합하는 방식을 취하고 있다.As shown in FIG. 1, in a vehicle assembly process or the like, the fastening operation of the bolt B 'and the nut N' is performed by first inserting the bolt B 'into the fastening structure 1' and then the nut N '. Is assembled, and a gripping tool such as a spanner is used to hold the head or threaded portion of the bolt B 'and force the nut to screw the bolt. At this time, if the bolt is not held by the holding tool, the fixing of the bolt B 'is essential because the rotation of the nut is accompanied by the rotation and the swing of the bolt, so that the pitch angle does not coincide and the torque is shifted so that the tightening operation cannot be performed completely. can do. However, if the working space for fixing the bolt (B ') with a holding tool is insufficient, the two bolts are joined by rotating the bolt (B') while the nut (N ') is welded to the fastening structure (1'). The way it is.

이상의 종래 기술에서 알 수 있듯이, 종래의 볼트-너트 체결방식은 볼트를 파지하고 너트를 가조립하는 부수 작업이 수반되어 불편하며, 작업 공간이 좁을 때 볼트를 고정하는 것이 어렵고 특히 볼트 고정을 위하여 두 명의 작업자가 필요한 경우 공간의 부족으로 말미암아 볼트 결합 작업을 원활히 수행할 수 없는 문제점이 있었다. As can be seen from the prior art, the conventional bolt-nut fastening method is inconvenient due to the additional work of gripping the bolt and pre-assemble the nut, it is difficult to secure the bolt when the working space is narrow, especially for fixing the bolt If a worker is required, there is a problem that the bolt can not be performed smoothly due to lack of space.

그러므로 본 발명은 자동차 조립 공정에 있어 볼트와 너트의 체결 작업을 간편히 하고, 공간이 협소한 곳에서도 원활하게 체결 작업을 수행할 수 있도록 개량된 볼트 구조를 제공하는 것을 목적으로 한다.Therefore, an object of the present invention is to provide an improved bolt structure to simplify the fastening operation of the bolt and nut in the automobile assembly process, and to perform the fastening operation smoothly even in a narrow space.

상기 목적을 달성하기 위한 본 발명의 자동차조립공정에 있어 체결 구조물에 볼트-너트 결합구조를 형성하기 위한 볼트 구조는, 상기 볼트의 로드부의 끝단부에 직육면체 형상의 공구파지부를 볼트와 일체로 형성하여 파지 공구로 상기 공구파지부를 잡고 볼트를 고정시킬 수 있도록 한 것을 특징으로 하고 있다.In the automobile assembly process of the present invention for achieving the above object, the bolt structure for forming the bolt-nut coupling structure to the fastening structure, the tool grip portion of the rectangular parallelepiped shape formed at the end of the rod portion of the bolt integrally with the bolt It is characterized in that the gripping tool to hold the tool holding portion to secure the bolt.

이러한 본 발명의 구성에 의하면, 최소한의 공간을 이용하여 볼트를 고정시키면서 너트를 체결하는 장점을 기대할 수 있게 된다.According to the configuration of the present invention, it is possible to expect the advantage of fastening the nut while fixing the bolt using a minimum space.

이하, 본 발명의 바람직한 실시예를 첨부 도면을 참조로 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에 도시한 것과 같이 본 발명의 볼트(B)는 로드부의 끝단부(20)상에 사각 형상의 공구파지부(10)를 설치하여 두고 있다. 상기 공구파지부(10)의 밑면은 끝단부의 중앙 지름 전체를 따라 설치되고, 그 위로 스패너등의 파지 공구가 충분히 잡을 수 있는 정도의 높이를 가지도록 몸체부가 연장되어 전체적으로 슬림형의 직육면체 형상을 취하고 있다. 공구파지부(10)는 주조, 프레스등의 볼트 제조 공정시 기존의 볼트와 같은 재료로 볼트와 일체로 성형되는 것이 바람직하다.As shown in FIG. 2, the bolt B of the present invention is provided with a tool holder 10 having a rectangular shape on the end portion 20 of the rod portion. The bottom surface of the tool holding portion 10 is installed along the entire center diameter of the end portion, the body portion is extended so as to have a height enough to hold a gripping tool such as a spanner thereon, taking the overall shape of a slim rectangular parallelepiped. . Tool holding portion 10 is preferably molded integrally with the bolts of the same material as the existing bolt during the manufacturing process of the bolt, such as casting, press.

또, 도 2에 도시한 본 발명의 볼트(B)는 공구파지부(10)를 너트가 체결되는 쪽인 로드부의 끝단에 배치하고, 공구파지부(10)의 폭이 로드부의 반경을 넘어 돌출되지 않게 구성하고 있다. 그러므로, 볼트(B)를 체결구조물에 기존과 같이 원활하게 삽입한 상태에서 스패너등의 파지공구로 공구파지부(10)를 잡아 볼트가 회전 내지 요동되지 않도록 한 후, 너트를 체결할 수 있어 체결 작업이 간편해지며, 너트 체결 공간만을 필요로 하므로 한 명의 작업자가 체결 작업을 효율적으로 수행할 수 있게 된다. 또, 볼트(B) 및 너트의 가용접이나 사전 고정 작업이 불필요하여 작업성이 우수하며, 너트의 회전각, 피치각등을 종전과 같이 확인할 수 있는 편리함이 있다. In addition, the bolt (B) of the present invention shown in Figure 2 arranges the tool holding portion 10 at the end of the rod portion which is the side to which the nut is fastened, the width of the tool holding portion 10 does not protrude beyond the radius of the rod portion I do not configure it. Therefore, while holding the tool holder 10 with a gripping tool such as a spanner while the bolt B is inserted into the fastening structure smoothly as before, the nut can be tightened after the bolt is not rotated or rocked. The work is simplified and only a nut fastening space is required so that one worker can perform the fastening work efficiently. In addition, there is no need for welding or pre-fixing of the bolts (B) and the nut, and thus the workability is excellent, and the rotation angle, the pitch angle, and the like of the nut can be confirmed as before.

이상 기술한 본 발명은 특히 자동차 조립 공정에 있어 볼트와 너트의 체결 작업을 간편히 하고, 공간이 협소한 곳에서도 원활하게 체결 작업을 수행할 수 있도록 하여 작업성이 우수하며 편리성을 증대시킨다는 효과를 발휘한다.The present invention described above makes it easy to fasten the bolts and nuts in the automobile assembly process, so that the fastening operation can be performed smoothly even in a narrow space, thereby improving the workability and increasing convenience. Exert.
