본 발명은 밸브설치통로내에 장착된 밸브스템실이 올바르게 장착되었는지를 작업자가 직접 확인할 수 있도록 하는 장치에 관한 기술이다.The present invention relates to a device for allowing the operator to directly check whether the valve stem chamber mounted in the valve installation passage is correctly mounted.

일반적으로, 엔진을 구성하는 실린더헤드(1)에는 도 1에 도시된 바와 같이 흡,배기밸브의 설치를 위한 밸브설치통로(2)가 흡,배기포트(3)와 연결되도록 형성된다.In general, the cylinder head (1) constituting the engine is formed so that the valve installation passage (2) for the installation of the intake, exhaust valve as shown in Figure 1 is connected to the intake, exhaust port (3).

여기서, 상기 밸브설치통로(2)에는 밸브의 직선왕복 이동을 안내하는 밸브가이드(4)가 설치되고, 상기 밸브가이드(4)의 상단부에는 밸브스템실(5)이 장착된다.Here, the valve guide passage 2 is provided with a valve guide 4 for guiding the linear reciprocating movement of the valve, and the valve stem chamber 5 is mounted at the upper end of the valve guide 4.

상기 밸브스템실(5)은 상기 밸브가이드(4)와 밸브스템간의 접촉면을 윤활시키는 엔진오일의 유입을 단속하게 된다.The valve stem chamber 5 interrupts the inflow of engine oil for lubricating the contact surface between the valve guide 4 and the valve stem.

한편, 상기와 같은 밸브스템실(5)은 조립지그를 통해 밸브설치통로(2)로 공급되어지며, 밸브설치통로(2)로 공급되어진 후에는 조립지그의 가압력에 의해 하단의 플랜지부(5a)가 상기 밸브설치통로(2)의 바닥면(2a)에 밀착됨으로써, 장착이 완료되는 구조이다.On the other hand, the valve stem chamber 5 as described above is supplied to the valve installation passage (2) through the assembling jig, and after being supplied to the valve installation passage (2), the flange portion 5a at the lower end by the pressing force of the assembly jig ) Adheres to the bottom surface 2a of the valve installation passage 2, whereby the mounting is completed.

이와 같이, 밸브스템실(5)이 장착될 때 밸브설치통로(2)의 바닥면(2a)에 이물질이 존재하게 되면, 상기 밸브스템실(5)은 삐뚤어진 상태로서 장착되어지고, 이 결과 밸브스템실(5)의 플랜지부(5a)와 상기 밸브설치통로(2)의 바닥면(2a)사이에 틈새가 발생하게 된다.In this way, when foreign matter is present on the bottom surface 2a of the valve installation passage 2 when the valve stem chamber 5 is mounted, the valve stem chamber 5 is mounted as a skewed state, and as a result, the valve A gap is generated between the flange portion 5a of the stem chamber 5 and the bottom surface 2a of the valve installation passage 2.

따라서, 밸브스템실(5)이 정상적으로 장착되지 못하면 엔진오일이 과도하게 소모되기 때문에, 이를 예방하는 것도 중요한 과제중 하나이다.Therefore, since the engine oil is excessively consumed when the valve stem chamber 5 is not normally mounted, it is also one of the important problems.

그러나, 종래에는 밸브설치통로(2)내에 장착 완료된 밸브스템실(5)이 올바르게 장착되었는지를 확인할 수가 없는 문제점이 있었다.However, conventionally, there has been a problem that it is not possible to confirm whether the valve stem chamber 5 which has been mounted in the valve installation passage 2 is correctly mounted.

한편, 상기와 같은 밸브스템실(10)은 조립지그를 통해 밸브설치통로(2)로 공급되어지며, 밸브설치통로(2)로 공급되어진 후에는 하단의 플랜지부(11)가 상기 밸브설치통로(2)의 바닥면(2a)에 밀착됨으로써, 장착이 완료되는 구조이다.On the other hand, the valve stem chamber 10 as described above is supplied to the valve installation passage (2) through the assembly jig, and after being supplied to the valve installation passage (2) the lower flange portion 11 of the valve installation passage By being in close contact with the bottom surface 2a of (2), it is a structure in which mounting is completed.

이와 같이, 밸브설치통로(2)내에 밸브스템실(10)의 장착이 완료되고 나면, 본 발명에 따른 밸브스템실 장착 확인장치를 이용해 밸브스템실(10)이 올바르게 장착되었는가를 검사하게 된다.Thus, after the installation of the valve stem chamber 10 in the valve installation passage (2) is completed, it is checked whether the valve stem chamber 10 is correctly mounted using the valve stem chamber mounting confirmation device according to the present invention.

즉, 본 발명에 따른 밸브스템실 장착 확인장치는 관통구멍(13)이 형성된 밸브스템실(10)을 포함하여, 상기 밸브설치통로(2)로 삽입되어 밸브스템실(10)을 밀폐시키도록 장착되면서 내부의 밀폐공간을 외부와 연결하도록 공기통로(21)가 형성된 실덮개블록(20)과, 상기 실덮개블록(20)의 공기통로(21)와 공기호스(31)를 통해 연결된 에어플로미터(30)와, 상기 에어플로미터(30)를 통해 상기 실덮개블록(20)의 내부 밀폐공간으로 에어를 공급하는 에어공급유닛(40)과, 상기 에어플로미터(30)로부터 신호를 전달받아 상기 실덮개블록(20)의 내부 밀폐공간에서 누출되는 에어량을 디스플레이하는 디스플레이유닛(50)으로 구성된다.That is, the valve stem chamber mounting confirmation apparatus according to the present invention includes a valve stem chamber 10 having a through hole 13 formed therein so as to be inserted into the valve installation passage 2 to seal the valve stem chamber 10. While being mounted, a seal cover block 20 in which an air passage 21 is formed to connect the sealed space inside to the outside, and an air flow connected through the air passage 21 and the air hose 31 of the seal cover block 20. The meter 30, the air supply unit 40 for supplying air to the inner sealed space of the seal cover block 20 through the air flow meter 30, and transmits a signal from the air flow meter (30) It is composed of a display unit 50 that receives and displays the amount of air leaking from the inner sealed space of the seal cover block 20.

여기서, 상기 실덮개블록(20)은, 상기 밸브설치통로(2)의 바닥면(2a)상에 중첩된 밸브스템실(10)의 플랜지부(11)를 가압하는 플랜지가압부(23)와, 상기 플랜지 가압부(23)의 내측에 오목한 모양으로 형성되어 상기 밸브스템실(10)을 밀폐시키는 밀폐홈(25)과, 상기 밀폐홈(25)의 윗면에 수직하방으로 돌출형성되어 상기 밸브스템실(10)의 상부구멍(15)을 밀폐시키는 밀폐돌기(27)를 갖추도록 형성된다.Here, the seal cover block 20, the flange pressing portion 23 for pressing the flange portion 11 of the valve stem chamber 10 superimposed on the bottom surface (2a) of the valve installation passage (2) and And a sealing groove 25 formed in a concave shape inside the flange pressing part 23 to seal the valve stem chamber 10 and protruding downwardly from an upper surface of the sealing groove 25 to form the valve. It is formed to have a sealing projection 27 for sealing the upper hole 15 of the stem chamber (10).

이에 따라, 상기 실덮개블록(20)에 형성된 공기통로(21)는 상기 밀폐홈(27)과 상기 공기호스(31)를 연결하도록 실덮개블록(20)을 관통하여 형성되는 구조이다.Accordingly, the air passage 21 formed in the seal cover block 20 is formed through the seal cover block 20 so as to connect the sealing groove 27 and the air hose 31.

그리고, 상기 관통구멍(13)은 상기 밸브스템실(10)의 외주면에서 상기 밸브설치통로(2)의 바닥면(2a)과 상기 밸브가이드(4) 및 상기 실덮개블록(20)의 플랜지가압부(23) 중 어느 한 부위와도 서로 접촉하지 않는 소정의 위치에 형성된다.The through hole 13 has a bottom surface 2a of the valve installation passage 2 and a flange of the valve guide 4 and the seal cover block 20 at the outer circumferential surface of the valve stem chamber 10. It is formed in the predetermined position which does not contact with any part of the pressure part 23, either.

또한, 상기 플랜지가압부(23)의 밑면에는 상기 플랜지부(11)와의 접촉성을 좋게 하기 위한 패드부재(60)가 일체로 결합된다.In addition, the bottom surface of the flange pressing portion 23 is integrally coupled to the pad member 60 for improving contact with the flange portion (11).

상기 패드부재(60)는 고무를 사용하는 것이 바람직하다.The pad member 60 is preferably made of rubber.

이하, 본 발명의 작용 및 효과에 대해 설명하기로 한다.Hereinafter, the operation and effects of the present invention will be described.

먼저, 조립지그를 통해 밸브설치통로(2)로 공급된 밸브스템실(10)은 그 하단의 플랜지부(11)가 상기 밸브설치통로(2)의 바닥면(2a)에 밀착되면서 장착된다.First, the valve stem chamber 10 supplied through the assembly jig to the valve installation passage 2 is mounted while the flange 11 at the lower end thereof comes into close contact with the bottom surface 2a of the valve installation passage 2.

이때, 밸브스템실(10)의 상단부는 밸브가이드(4)의 상부측에 압착되면서 장착된다.At this time, the upper end of the valve stem chamber 10 is mounted while being pressed on the upper side of the valve guide (4).

이와 같이, 밸브스템실(10)의 장착이 완료되고 나면, 또 다른 지그를 통해 실덮개블록(20)이 밸브설치통로(2)로 공급되어지고, 상기 밸브설치통로(2)로 공급되어진 실덮개블록(20)은 플랜지가압부(23)가 밸브스템실(10)의 플랜지부(11)를 가 압하는 상태로 장착된다.As such, after the mounting of the valve stem chamber 10 is completed, the seal cover block 20 is supplied to the valve installation passage 2 through another jig, and the chamber supplied to the valve installation passage 2. The cover block 20 is mounted in a state in which the flange pressing portion 23 presses the flange portion 11 of the valve stem chamber 10.

이때, 상기 플랜지가압부(23)에 결합된 패드부재(60)는 상기 플랜지부(11)와 직접 접촉하게 됨으로써, 플랜지가압부(23)와 플랜지부(11)사이의 기밀을 유지시키게 된다.At this time, the pad member 60 coupled to the flange pressing portion 23 is in direct contact with the flange portion 11, thereby maintaining the airtightness between the flange pressing portion 23 and the flange portion 11.

상기와 같이, 실덮개블록(20)의 장착이 완료되고 나면 에어공급유닛(40)으로부터 일정량의 에어가 공급된다.As described above, after the mounting of the seal cover block 20 is completed, a predetermined amount of air is supplied from the air supply unit 40.

상기 에어는 에어플로미터(30)와 공기호스(31) 및 공기통로(21)를 경유하여 실덮개블록(20)의 밀폐홈(25)으로 공급되어지고, 상기 밀폐홈(25)내에서는 관통구멍(13)을 통해 밸브스템실(10)의 내부로도 공급되어 진다.The air is supplied to the sealed groove 25 of the seal cover 20 through the air flow meter 30, the air hose 31, and the air passage 21, and penetrates through the sealed groove 25. It is also supplied into the valve stem chamber 10 through the hole 13.

이와 같이, 일정량의 에어가 일정시간동안 공급되었을 때 상기 밀폐홈(25)의 공간이 완전히 밀폐된 상태라면, 상기 밀폐홈(25)으로부터 누출되는 에어는 제로(zero)인 상태가 되고, 또한 에어공급유닛(40)으로부터는 더 이상의 에어공급이 진행되지 않게 된다.As such, if the space of the sealed groove 25 is completely sealed when a certain amount of air is supplied for a predetermined time, the air leaking from the sealed groove 25 is in a zero state, and air From the supply unit 40 no further air supply proceeds.

따라서, 디스플레이유닛(50)은 에어플로미터(30)로부터 이때의 상황을 신호로서 전달받아 표시하게 되고, 작업자는 디스플레이유닛(50)을 통해 밸브설치통로(2)내에 밸브스템실(10)이 정상적으로 장착되었음을 육안으로 확인할 수 있게 된다.Therefore, the display unit 50 receives and displays the situation at this time from the air flow meter 30 as a signal, and the operator has the valve stem chamber 10 in the valve installation passage 2 through the display unit 50. It can be confirmed visually that the installation is normal.

그런데, 상기 밀폐홈(25)의 공간이 완전히 밀폐된 상태가 아니라면, 일정시간이 지난후에도 에어의 공급은 계속해서 진행되게 된다.By the way, if the space of the sealed groove 25 is not completely sealed, the supply of air continues to proceed even after a certain time.

이는, 밀폐홈(25)으로부터 에어가 누출되는 상황이기 때문에 누출되는 에어 만큼 계속해서 새로운 에어가 공급되는 것이다.This is because new air is continuously supplied as much as the air leaks because the air leaks from the sealed groove 25.

이때에도, 디스플레이유닛(50)은 에어플로미터(30)로부터 신호로서 전달받아 이때이 상황을 표시하게 된다.In this case, the display unit 50 receives the signal from the air flow meter 30 to display the situation at this time.

따라서, 작업자는 디스플레이유닛(50)을 통해 나타난 수치나 또는 그래프등을 보고, 누출되는 에어의 양이 정상 상태인지 또는 비정상 상태인지를 판단하게 된다.Therefore, the operator looks at the numerical value or graph displayed through the display unit 50, and determines whether the amount of air leaked is in a normal state or an abnormal state.

만약, 누출되는 에어의 양이 비정상 상태이면 밸브설치통로(2)내에 장착된 밸브스템실(10)은 비정상적으로 장착된 상태이므로, 작업자는 비정상적으로 장착된 밸브스템실(10)을 재 장착시킨 다음, 상기와 같은 절차를 반복 수행하여 밸브스템실(10)의 올바른 장착을 실현시키게 된다.If the amount of leaked air is abnormal, the valve stem chamber 10 mounted in the valve installation passage 2 is abnormally mounted. Therefore, the operator may refit the abnormally mounted valve stem chamber 10. Next, by repeating the above procedure to realize the correct mounting of the valve stem chamber (10).

따라서, 본 발명은 밸브설치통로(2)내에 장착된 밸브스템실(10)의 장착상태를 작업자가 직접 확인할 수 있게 됨으로써, 항상 밸브스템실(10)의 올바른 장착을 실현할 수 있게 되고, 이 결과 엔진오일이 불필요한 낭비를 없앨 수 있게 되며, 더 나아가서는 엔진의 내구성능을 크게 향상시킬 수 있게 된다.Therefore, the present invention enables the operator to directly check the mounting state of the valve stem chamber 10 mounted in the valve installation passage 2, so that the correct mounting of the valve stem chamber 10 can always be realized. Engine oil can eliminate unnecessary waste, and further improve the durability of the engine.

이상 설명한 바와 같이 본 발명에 의하면, 밸브설치통로내에 장착된 밸브스템실의 상태를 작업자가 직접 확인할 수 있게 됨으로써, 항상 밸브스템실의 올바른 장착을 실현할 수 있는 효과가 있게 된다.As described above, according to the present invention, since the operator can directly check the state of the valve stem chamber mounted in the valve installation passage, there is an effect that the correct mounting of the valve stem chamber can always be realized.
