도 3은 본 고안 샤프트와 레버의 체결구조를 나타낸 분리사시도이다.3 is an exploded perspective view showing a fastening structure of the shaft and lever of the present invention.
샤프트(2)의 일단에 원형의 나사부(13)를 형성하고 이를 레버(1)에 형성된 레버홀(11)에 삽입하여 너트(3)로 고정설치하되, 샤프트(2)와 레버(1)의 사이에 심(12)을 설치하고, 나사부(13)에 핀홀(15)을 형성하여 이에 핀(14)을 양끝단이 돌출되도록 삽입설치하며, 핀(14)의 돌출부가 삽입되어 고정되도록 레버(1)의 레버홀(11) 양측에 핀삽입홈(10)을 형성하여 구성한 것이다.A circular screw portion 13 is formed at one end of the shaft 2 and inserted into the lever hole 11 formed in the lever 1 to be fixedly installed with the nut 3, but the shaft 2 and the lever 1 The shim 12 is installed between the pins, and the pin hole 15 is formed in the threaded portion 13 so that the pin 14 is inserted so that both ends protrude therefrom, and the protrusion of the pin 14 is inserted into and fixed to the lever ( The pin insertion grooves 10 are formed on both sides of the lever hole 11 of 1).
상기와 같이 구성된 본 고안의 작용을 살펴본다.Looking at the operation of the present invention configured as described above.
우선 본 고안 샤프트와 레버의 체결구조를 이용하여 샤프트와 레버를 조립하고저 할 때에는, 우선 샤프트(2)의 나사부(13)에 심(12)을 삽입하고, 핀홀(15)에 핀(14)을 삽입하여 핀(14)의 양단이 나사부(13)의 외측으로 돌출되도록 하고, 나사부(13)가 레버(1)의 레버홀(11)에 삽입됨과 동시에 나사부(13)에 삽입된 핀(14)의 양측 돌출부가 핀삽입홈(10)에 삽입 고정한 후 레버(1)의 일측으로 돌출된 나사부(13)에 너트(3)를 체결하는 것이다.First, in order to assemble the shaft and the lever using the coupling structure of the shaft and lever of the present invention, first, the shim 12 is inserted into the threaded portion 13 of the shaft 2, and the pin 14 is inserted into the pinhole 15. To insert both ends of the pin 14 to protrude to the outside of the threaded portion 13, and the threaded portion 13 is inserted into the lever hole 11 of the lever 1 and the pin 14 inserted into the threaded portion 13 at the same time. After both sides of the protrusions are inserted into and fixed in the pin insertion groove 10, the nut 3 is fastened to the screw 13 protruding to one side of the lever 1.
이와 같이 구성된 샤프트와 레버의 체결구조는 종래의 체결구조와 같이 레버와 샤프트의 나사부에 절단면을 구비한 원형의 결합부를 형성함에 따른 가공의 어려움을 해소할 수 있도록 샤프트(2)의 나사부(13)를 보통의 원형 나사부(13)로 형성하여 이에 핀홀(15)을 형성하며, 레버(1)의 레버홀(11) 역시 일반 원형의 홀을 형성하고 가공이 용이한 핀삽입홈(10)을 형성하므로서, 샤프트(2)와 레버(1)의 접촉면적을 최대화 함은 물론 가공의 오차를 최소화하여 정밀 가공을 가능케 하여 체결력과 정밀제어력을 크게 향상시킬 수 있는 것이다.The coupling structure of the shaft and the lever configured as described above has the screw portion 13 of the shaft 2 so as to solve the difficulty of processing by forming a circular coupling portion having a cutting surface in the lever and the screw portion of the shaft as in the conventional coupling structure. To form a common circular screw 13 to form a pinhole 15, the lever hole 11 of the lever 1 also forms a general circular hole and forms a pin insertion groove 10 that is easy to process. As a result, the contact area between the shaft 2 and the lever 1 can be maximized, as well as minimizing machining errors to enable precision machining, thereby greatly improving the tightening force and the precise control force.
상기와 같이 본 고안 연료분사장치의 샤프트와 레버의 체결구조는 샤프트의 끝단에 원형의 나사부를 형성하고 이에 핀을 삽입하여 레버에 형성된 핀삽입홈에 핀이 삽입 고정되도록 구성하므로서, 샤프트와 레버의 접합면적을 최대화 하여 체결력을 향상시키므로서 종래의 체결방식보다 체결력과 정밀제어등을 개선할 수 있는 효과가 있는 것이다.As described above, the coupling structure between the shaft and the lever of the fuel injection device of the present invention forms a circular screw portion at the end of the shaft and inserts the pin into the pin insertion groove formed in the lever, thereby fixing the pin to the pin insertion groove. By maximizing the bonding area to improve the fastening force, there is an effect that can improve the fastening force and precision control than the conventional fastening method.
