[산업상 이용 분야][Industrial use]
본원 발명은 자동차 엔진의 흡배기 밸브와 실린더 헤드의 밸브좌(Valve seat)와의 접촉성을 검사하기 위한 검사방법 및 그를 위한 장치에 관한 것이다.The present invention relates to an inspection method for inspecting the contact between the intake and exhaust valves of an automobile engine and the valve seat of a cylinder head, and an apparatus therefor.
[종래기술][Private Technology]
일반적으로 흡배기 밸브와 실린더 헤드의 밸브시트의 접촉성이 나쁘면 압축 또는 연소가스의 누설이 발생하고 엔진의 출력을 저해하는 문제점이 발생하게 딘다.In general, when the contact between the intake and exhaust valves and the valve seat of the cylinder head is bad, there is a problem of leakage of compression or combustion gas and deterioration of the engine output.
이에 따라 흡배기 밸브와 실린더 헤드에 형성된 밸브시트와의 밀착성 시험은 엔진제작 시험의 중요한 과정중 하나가 되고 있으나 흡배기밸브의 반복된 개폐작동에 따른 밸브시트와의 접촉성(밀착성)을 검사하기 위한 종래 시험검사 방법으로는 인주를 밸브에 바른 후 밸브시트에 인주가 묻어나는 인주 흔적으로 접촉성의 균일 유무를 확인하는 원시적인 방법이 현재가지 사용되고 있다.Accordingly, the adhesion test between the intake and exhaust valve and the valve seat formed on the cylinder head has become one of the important processes of the engine production test, but the conventional method for inspecting the contact (adhesiveness) with the valve seat in accordance with the repeated opening and closing operation of the intake and exhaust valve. As a test method, a primitive method is currently used to check the uniformity of contact by applying a pad to the valve, and a track of padding on the valve seat.
한편 또다른 밸브개폐 내구 시험에 따른 접촉성 검사 방법으로는 담배연기등을 흡기 및 배기포트에 불어넣어 밸브와 밸브시트 사이로 누설되는가의 여부를 육안으로 확인하는 방법등이 사용되고 있다.On the other hand, as a method of contact test according to another valve opening / closing endurance test, a method of visually confirming whether or not the cigarette smoke is leaked between the valve and the valve seat is blown into the intake and exhaust ports.
[종래기술의 문제점][Problems with Prior Art]
그러나 상기와 같은 인주에 의한 밀착성 시험의 경우 검사 작업시간이 길고 이물질이 묻어나 불결해지며 반복시험시마다 닦아내고 다시 시작해야 하며 인주의 묻어남이 접촉상태를 정확히 반영하기 곤란하다는 문제점이 지적되고 있으며 연기 누설에 의한 접촉성 시험방법 역시 연기가 틈새를 통하여 누설되더라도 공기중에 확산을 일으키게 되어 정확한 누설 위치의 판정이 어렵다는 문제점이 있는 것이었다.However, it is pointed out that in the case of the adhesion test by the above-mentioned rod, the inspection work is long, foreign matters get dirty and become dirty, and each repetitive test should be wiped off and restarted. The contact test method also had a problem in that even if smoke leaked through a gap, it caused diffusion in the air, so that it was difficult to determine an accurate leak position.
[발명이 해결하고자 하는 과제][Problem to Solve Invention]
이에 본원 발명은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 하는 바는 엔진블럭 특히 실린더 헤드의 내구성 시험에 있어서 밸브의 반복적인 개폐작동에 따른 밸브시트와의 접촉성(밀착성)여부를 즉시 손쉽게 확인할 수 있는 검사방법 및 검사장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and its object is to readily check whether the contact with the valve seat (adhesiveness) due to the repeated opening and closing operation of the valve in the engine block, especially the cylinder head durability test.

[실시예]EXAMPLE
이하 본 발명의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
제1도는 본 발명에 의한 밸브와 밸브시트와의 접촉성 시험검사장치의 일실시예를 나타내는 도면이다.1 is a view showing an embodiment of a contact test test device between the valve and the valve seat according to the present invention.
도면중 부호1은 실린더 헤드이며 부호2는 흡기(또는 배기)밸브이며 부호3은 흡기(또는 배기)포트이며 부호4는 밸브시트이다.In the figure, reference numeral 1 denotes a cylinder head, reference numeral 2 denotes an intake (or exhaust) valve, reference numeral 3 denotes an intake (or exhaust) port, and reference numeral 4 denotes a valve seat.
상기 밸브(2)는 흡입 및 배기과정시 상·하로 반복작동하여 흡배기포트(3)를 실린더 내부와 연통되거나 또는 폐쇄하게 된다.The valve 2 is repeatedly operated up and down during the intake and exhaust process so that the intake and exhaust port 3 communicates with or closes the inside of the cylinder.
그런데 밸브(2)와 실린더 헤드의 밸브시트(4)와의 접촉성(밀차성)이 나쁘면 압축 및 폭발시 틈새를 통하여 연소가스가 누설되므로 엔진의 출력이 저하되고 배기행정시에는 흡기밸브를 통해 배기가스가 역류하게되어 엔진 성능을 현저하게 떨어드리게 되므로 밸브(2)와 밸브시트(4)의 변함없는 균일한 접촉성 유지가 매우 중요하며 이를위해 밸브(2)의 반복작동에 따른 접촉성 여부를 본 발명의 광케이블 장치를 통하여 손쉽게 확인하는 것이 가능하다.However, if the contact between the valve 2 and the valve seat 4 of the cylinder head is poor, the combustion gas leaks through the gap during compression and explosion, so that the output of the engine is lowered and the exhaust gas is exhausted through the intake valve. As the gas flows backward, the performance of the engine is remarkably degraded. Therefore, it is very important to maintain constant contact between the valve 2 and the valve seat 4 so that the contact between the valves 2 and the repeated operation of the valve 2 is very important. It is possible to easily check through the optical cable device of the present invention.
본 발명의 검사장치는 광원(5)을 내부에 수용하고 있는 본체(6)와 상기 광원(5)에의 전원공급을 온·오프시키는 전원스위치(7)와, 상기 본체(6)의 광원(5)부위로부터 외부로 길게 돌출되어지는 광케이블(8)과로 구성되어 있다.The inspection apparatus of the present invention includes a main body 6 accommodating the light source 5 therein, a power switch 7 for turning on and off a power supply to the light source 5, and a light source 5 of the main body 6. And an optical cable 8 that protrudes outwardly from the portion.
상기 광케이블(8)은 광원(5)이 점들될 때 빛을 안내하여 그의 끝단을 통해 빛을 사방으로 조사하게 되며 실린더 헤드(1)의 흡배기포트(3)를 통해 삽입되어 밸브(2)에 이를만큼 충분한 길이를 가진다.The optical cable 8 guides the light when the light source 5 is dotted to irradiate the light through the end thereof, and is inserted through the intake and exhaust port 3 of the cylinder head 1 to the valve 2. Have enough length.
이상과 같은 본원 발명의 검사장치를 이용하여 밸브와 밸브시트의 접촉성을 시험검사하는 방법은 다음과 같다.The method for testing the contact between the valve and the valve seat using the inspection device of the present invention as described above is as follows.
밸브의 개폐작동을 반복하는 과정중의 도중마다 밸브(2)를 밸브시트(4)에 밀착시킨 후 실린더 헤드(1)의 흡배기포트(3)를 통하여 밸브(2)에 다다를때까지 검사장치의 광케이블(8)을 삽입시킨다.In the middle of repeating the opening and closing operation of the valve, the valve 2 is brought into close contact with the valve seat 4, and then the inspection device is opened through the intake and exhaust port 3 of the cylinder head 1 until the valve 2 is reached. Insert the optical cable (8).
그런다음 전원스위치(7)를 온시키면 광원(5)이 점등되며 광원(5)으로부터의 불빛은 광케이블(8)을 통하여 유도 안내되어 그의 선단부(9)에서 빛을 조사하게 된다.Then, when the power switch 7 is turned on, the light source 5 is turned on, and the light from the light source 5 is guided through the optical cable 8 to irradiate light from its front end 9.
이때 만일 밸브(2)와 밸브시트(4)와의 밀착성이 좋지 아니하다면 그의 틈새를 통해 빛이 새어나오게 되며 검사자는 육안(10)으로 이 빛을 보고서 밀착성의 불량여부를 확인하게 되는 것이다.In this case, if the adhesion between the valve 2 and the valve seat 4 is not good, light leaks through his gap, and the inspector sees the light with the naked eye 10 to check whether the adhesion is poor.
[효과][effect]
이상과 같은 본원 발명에 의하면 좁고 굴곡진 깊숙한 곳까지 자유롭게 삽입할 수 있는 광케이블을 실린더 헤드의 흡배기포트를 통해 밸브에까지 삽입한 후 외부의 광원으로부터 발산되는 빛을 광케이블이 안내하여 밸브와 밸브시트와의 틈새로 조사하게 되므로써 이 틈새를 통해 흘러나오는 불빛을 보고 밀착성을 쉽게 확인할 수 있기 때문에 작업시간이 단축되고 정확한 확인이 가능하다는 효과가 있다.According to the present invention as described above is inserted into the valve through the intake and exhaust port of the cylinder head can be inserted freely to the narrow and deep deep to the valve and the optical cable guides the light emitted from the external light source to the valve and the valve seat By inspecting through the gap, the light flowing through the gap can be easily seen by checking the adhesion, which shortens the working time and makes it possible to confirm accurately.
