상기 고정기구는 덮개(18)의 개구부(34)에 직선 이동되도록 끼워지고 작업자가 조작하는 레버(36)와, 이 레버(36)의 하측에 설치되어 일정 탄성력을 부여하는 판스프링(38)과, 상기 판스프링(38)이 고정되도록 케이스(2)의 내측에 형성되는 판스프링 고정부(40)와, 상기 레버(36)에서 피동 스프로킷(6)의 방향으로 돌출되어 레버(36)를 이동시키면 피동 스프로킷의 기어부(30)에 걸림되어 피동 스프로킷(6)을 고정시키는 돌기부(42)로 이루어진다.The fixing mechanism includes a lever 36 inserted into the opening 34 of the cover 18 and operated by a worker, and a leaf spring 38 installed below the lever 36 to impart a predetermined elastic force. In addition, the leaf spring fixing portion 40 formed inside the case 2 so that the leaf spring 38 is fixed, and protrudes from the lever 36 in the direction of the driven sprocket 6 to move the lever 36. The lower portion is composed of a projection 42 which is caught by the gear portion 30 of the driven sprocket and fixes the driven sprocket 6.

이와 같이 이루어진 본 발명에 따른 차체 조립용 공구의 작용을 다음에서 설명한다.The operation of the vehicle body assembling tool according to the present invention thus made will be described below.

도 4는 본 발명에 따른 차체 조립용 공구의 사용 상태를 나타낸 일실시예로서, 차체 패널(46)과 범퍼 프레임(50)을 연결하는 볼트 조립 부위를 나타낸 것이다.Figure 4 is an embodiment showing a state of use of the vehicle body assembly tool according to the present invention, it shows a bolt assembly portion connecting the body panel 46 and the bumper frame 50.

즉, 차체 패널(46)의 내측에 범퍼 멤버(48)가 용접 등의 방법으로 고정되고, 이 범퍼 멤버(48)의 측면에 범퍼 프레임(50)을 맞대기한 후 볼트(12)를 조립한다.이때 범퍼 멤버(48)의 내측에는 너트(52)가 용접에 의해 부착된다.That is, the bumper member 48 is fixed to the inner side of the vehicle body panel 46 by welding or the like, and the bolt 12 is assembled after abutting the bumper frame 50 on the side surface of the bumper member 48. At this time, the nut 52 is attached to the inside of the bumper member 48 by welding.

여기에서 상기 볼트머리에 피동 스프로켓(6)을 끼우고 구동 스프로킷(4)에 전동공구(8)를 끼운 뒤 전공공구(8)를 작동시키면 구동 스프로킷(4)이 회전되면서 체인(9)에 의해 구동력이 피동 스프로킷(6)으로 전달되어 피동 스프로킷(6)이 회전되면서 볼트(12)의 조임 및 풀림 작용을 이루어진다.Here, the driven sprocket 6 is inserted into the bolt head and the power tool 8 is inserted into the drive sprocket 4, and then the electric tool 8 is operated. As the driving force is transmitted to the driven sprocket 6, the driven sprocket 6 is rotated to perform tightening and releasing action of the bolt 12.

이때, 공구를 수동으로 사용하고자 할 경우에는 레버(36)를 직선 이동시키면 레버의 돌기(42)가 피동 스프로킷의 나사부(30)에 걸림되어 피동 스프로킷(6)을 고정시킨다.At this time, in the case where the tool is to be used manually, the projections 42 of the levers are caught by the threaded portions 30 of the driven sprockets to fix the driven sprockets 6 by linearly moving the levers 36.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 차체 조립용 공구는 공간 협소하여 전동공구를 직접 연결하기 힘든 부위에 공구를 설치하여 전동공구의 구동력을 볼트로 전달되도록 함으로써, 공간이 협소한 부위에도 전동공구의 사용을 가능하게 하여 사용의 편리성을 증대시키고, 조립시간을 줄일 수 있는 이점이 있다.Therefore, the tool for assembling the vehicle body according to the present invention constructed and acted as described above has a narrow space so that the tool is installed in a region where it is difficult to directly connect the power tool, so that the driving force of the power tool is transmitted to the bolt, where the space is narrow. Edo also enables the use of power tools to increase the convenience of use, there is an advantage that can reduce the assembly time.
