Abstract
Description
본 발명은 밸브리테이너를 밸브에 고정시키기 위해 장착하는 밸브코터의 조립을 용이하게 하는 지그장치에 관한 것이다.The present invention relates to a jig device that facilitates assembly of a valve coater for mounting a valve retainer to a valve.
흡배기포트를 개폐하는 흡배기밸브(20)는 제3도에 도시하는 것과 같이 캠 또는 로커암(21)에 의해 하강되어 개방된 후 복귀 작동은 밸브스프링(22)의 탄발력에 의하고 있다.As shown in FIG. 3, the intake and exhaust valve 20 for opening and closing the intake and exhaust port is lowered and opened by the cam or rocker arm 21, and the return operation is based on the elastic force of the valve spring 22. As shown in FIG.
따라서 밸브(20)가 하강시에 실린더헤드에 의해 지지되는 밸브스프링(22)을 압축하기 위한 수단으로 밸브리테이너(23)가 밸브(20)에 고정되게 된다. 이 때 밸브리테이너(23)를 밸브(20)에 끼워 특정 위치에 고정시키기 위해서 2개로 분할된 밸브코터(24)를 밸브(20)의 고정홈(25)에 끼워지도록 맞추게 된다.Therefore, the valve retainer 23 is fixed to the valve 20 as a means for compressing the valve spring 22 supported by the cylinder head when the valve 20 is lowered. At this time, in order to fix the valve retainer 23 to the valve 20 to be fixed at a specific position, the valve coater 24 divided into two is fitted to fit in the fixing groove 25 of the valve 20.
그러나 밸브코터(24)를 끼워 맞추기 위해서는 밸브리테이너(23)를 큰 힘으로 내리눌러 밸브스프링(22)을 압착시켜 고정홈(5)을 노출시킨 다음 밸브코터(24)를 양측에서 밸브(20)이 표면에 맞대고 밸브스프링(22)의 압력을 해제하게 되며 이 때 밸브스프링(22)의 탄발력으로 밸브리테이너(23)가 상승하면서 경사면(26)에 밀착하면 밸브스프링(22)의 탄발력에 의해 밸브리테이너(23)와 조립된 밸브코터(24)가 벗어나지 않고 밸브(20)의 상하 작동에 밸브코터(24)와 밸브리테이너(23)와 함께 작동하게 되는 것이어서 밸브코터를 조립시 밸브스프링(22)을 압축시키는데 큰 힘이 소요되어지게 되나 종래의 경우 이를 압축하기 편리한 전용 장비가 구비되어 있지 못하여 밸브조립 및 정비에 많은 시간이 소요되는 불편함이 있었다.However, in order to fit the valve coater 24, the valve retainer 23 is pressed down with great force to squeeze the valve spring 22 to expose the fixing groove 5, and then the valve coater 24 is opened on both sides of the valve 20. The pressure of the valve spring 22 is released against the surface. At this time, when the valve retainer 23 rises due to the elastic force of the valve spring 22, the valve retainer 23 rises and adheres to the inclined surface 26 to the elastic force of the valve spring 22. As a result, the valve coater 24 assembled with the valve retainer 23 is operated together with the valve coater 24 and the valve retainer 23 in the up and down operation of the valve 20 without disengaging the valve spring. 22) A large force is required to compress, but in the conventional case, since there is no dedicated equipment for convenient compression, there is an inconvenience in that a lot of time is required for assembly and maintenance of the valve.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 밸브코터의 조립을 용이하게 하여 밸브조립 및 정비 작업 시간을 단축시킬 수 있는 밸브코터 조립을 위한 지그장치를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its object is to provide a jig device for assembling the valve coater which can facilitate the assembly of the valve coater and shorten the valve assembly and maintenance work time.

도면중 부호 1은 좌우 고정지지대이며 좌우 고정지지대에는 크로스바(2)가 가로질러 회전가능하게 지지되도록 설치되어 있다. 상기 크로스바(2)에는 슬라이딩 원통부(3)를 통해 작동로드(4)가 축방향을 따라 좌우 이동 및 회동을 허용토록 계합되어 있다. 그리고 상기 작동로드(4) 단부에는 손잡이(5)가 형성되고 상기 손잡이(5)는 작동로드(4)에 대해 전체 길이를 조정할 수 있게 슬라이딩 이동 가능하게 접속된다.Reference numeral 1 in the drawings is a left and right fixed support, and the left and right fixed support is provided so that the crossbar 2 is rotatably supported across. The working rod 4 is engaged with the crossbar 2 through the sliding cylindrical portion 3 to allow left and right movement and rotation along the axial direction. In addition, a handle 5 is formed at the end of the operating rod 4, and the handle 5 is slidably connected to adjust the overall length with respect to the operating rod 4.
또한 상기 작동로드(4)에는 밸브스프링 압착구(6)가 회동을 허용하는 구조로 연결되어 수직 하방으로 늘어져 있으며 밸브스프링 압착구(6)의 하단에는 밸브(7)스템의 통과를 허용하는 구멍(8)을 갖는 링부재(9)가 일체로 형성되어 있다.In addition, the valve spring presser 6 is connected to the operation rod 4 in a structure allowing rotation, and is vertically stretched downward, and a hole allowing the passage of the valve 7 stem at the lower end of the valve spring presser 6. The ring member 9 having the number 8 is integrally formed.
여기서 미설명 부호 10은 실린더헤드이다.Here, reference numeral 10 is a cylinder head.
이상과 같은 본 발명 장치에 의한 밸브코터(11)의 조립 과정을 다음과 같다.The assembly process of the valve coater 11 according to the present invention as described above is as follows.
밸브(7)를 실린더헤드(10)에 끼운 상태에서 밸브스프링(12)을 끼우고 밸브스프링(12)의 상부에 밸브리테이너(13)를 올려놓는다. 다음에 손잡이(5)를 크로스바(2)를 따라 움직여 밸브스프링 압착구(6)의 링부재(9)가 밸브(7) 중앙에 위치토록 한 다음 손잡이(5)를 내리누른다.The valve spring 12 is inserted in the state in which the valve 7 is inserted into the cylinder head 10, and the valve retainer 13 is placed on the valve spring 12. Next, the handle 5 is moved along the crossbar 2 so that the ring member 9 of the valve spring presser 6 is positioned at the center of the valve 7, and then the handle 5 is pressed down.
이 때 밸브스프링(12)의 탄성력이 커서 더 큰 힘이 필요할 때에는 손잡이(5)를 작동로드(4)로부터 후퇴시켜 전체 길이를 길게하므로써 모우먼트를 크게 발생시킬 수 있도록 조정한다. 손잡이(5)를 내리누르게 되면 밸브스프링 압착구(6)가 하강하면서 하단의 링부재(9)가 밸브리테이너(13)를 통해 밸브스프링(12)을 압축시키게 되며 밸브스프링(12)이 압축되면 밸브(7) 상단이 링부재(9)의 구멍(8)을 통하여 상부측으로 돌출되고 고정홈(14)이 드러나게 된다.At this time, when the elastic force of the valve spring 12 is large and a larger force is required, the handle 5 is retracted from the operating rod 4 so as to increase the overall length so that the moment can be generated largely. When the knob 5 is pressed down, the valve spring presser 6 descends and the lower ring member 9 compresses the valve spring 12 through the valve retainer 13, and the valve spring 12 is compressed. The upper end of the valve 7 protrudes upward through the hole 8 of the ring member 9 and the fixing groove 14 is exposed.
이 상태에서 2조각으로 분할된 밸브코터(11)를 내측 돌기부(15)가 고정홈(14)에 계합되도록 맞춘 상태에서 손잡이(5)의 내리누름력을 서서히 감소시키게 되면 밸브스프링(12)의 복원력으로 밸브리테이너(13)가 밸브(7) 상부로 상승하게 되며 양측 경사부(16)(17)가 당접하게 되면 밸브코터(11)와 밸브리테이너(13)는 밸브(7)와 한 몸체를 이루도록 조립이 완성되는 것이다.In this state, when the valve coater 11 divided into two pieces is fitted so that the inner protrusion 15 is engaged with the fixing groove 14, the pressing force of the handle 5 is gradually reduced. When the valve retainer 13 is raised above the valve 7 by the restoring force, and the two inclined portions 16 and 17 come into contact with each other, the valve coater 11 and the valve retainer 13 connect the valve 7 and one body. The assembly is completed to achieve.
만일 분해시에는 같은 모양으로 손잡이(5)를 내리누르면 링부재(9)가 밸브리테이너(13)와 밸브스프링(12)을 하강시키게 되므로써 밸브코터(11)의 외부 구속 상태가 해제되어 간단히 분해되어지게 된다.When disassembling, if the handle 5 is pushed down in the same shape, the ring member 9 lowers the valve retainer 13 and the valve spring 12, thereby releasing the external restraint state of the valve coater 11 and disassembling it. You lose.
이상과 같은 본 발명에 의하면 밸브의 조립 및 분해시 간단한 장치로 큰 힘을 들이지 않고도 밸브리테이너를 내리눌러 밸브스프링을 압축시키는 것이 가능하여 밸브코터의 탈 장착이 손쉬워 밸브조립 및 정비 시간을 크게 단축시키는 것이 가능하다.According to the present invention as described above, it is possible to compress the valve spring by pressing the valve retainer without a large force with a simple device when assembling and disassembling the valve, so that the valve coater can be easily attached and detached, thereby greatly shortening the valve assembly and maintenance time. It is possible.
