본 발명은 밸브스프링의 서어징측정장치에서 스트레인게이지 설치구조에 관한 것으로서, 특히 밸브스프링의 회전으로 인한 게이지의 구리선이 끊어지는 것을 방지하는 것이다.The present invention relates to a strain gauge mounting structure in the surge spring measuring device of the valve spring, in particular to prevent the copper wire of the gauge is broken due to the rotation of the valve spring.
일반적으로 혼합기의 폭발이 일어나는 연소실에 설치되는 흡배기장치인 밸브의 편마모를 방지하기 위해 기관의 회전에 비례하여 일정한 속도로 회전됨으로서, 밸브에 설치된 밸브스프링은 밸브의 직선왕복운동에 의하여 일정한 응력을 계속 받아왔다.In general, in order to prevent uneven wear of the valve, which is an intake / exhaust device installed in the combustion chamber where the explosion of the mixer occurs, the valve spring rotates at a constant speed in proportion to the rotation of the engine. Have been received.
그러나 코일형인 밸브스프링은 서징현상인 고유한 진동수를 가지고 있어 밸브의 직선왕복운동에 의한 진동수와 밸브스프링이 갖는 고유의 진동수가 일치한 경우 밸브스프링이 파손되는 문제점이 있었다.However, the coil-type valve spring has a unique frequency, which is a surging phenomenon, so that the valve spring breaks when the frequency due to the linear reciprocation of the valve coincides with the inherent frequency of the valve spring.
이러한 문제점을 고려하여 종래에는 이러한 밸브스프링의 서징현상을 정확히 측정하여 실차에 반영하는 것이 중요한 문제로 부각되었다.In consideration of such a problem, it has been highlighted in the related art that the surging phenomenon of the valve spring is accurately measured and reflected in the actual vehicle.
이러한 밸브스프링의 서어징측정장치를 제1도에 도시한 바와 같이 이하에서 설명하면 편마모를 방지하기 위해 회전하는 밸브(1)와, 상기 밸브(1)에 설치된 스프링시트(2)와 상기 스프링시트(2)에 밸브(1)를 복귀시키기 위해 안착된 밸브스프링(3)으로 이루어지는 밸브구조에 있어서, 상기 밸브스프링(3)에 설치되어 밸브(1)의 직선왕복운동에 따른 체적변화를 저항값의 변화로 측정하는 스트레인게이지(4)와, 상기 스트레인게이지(4)로 부터 출력된 전류를 받아 이를 증폭하는 앰프리파이어(5)와, 상기 앰프리파이어(5)로 부터 증폭된 전류를 받아 이를 사용자가 식별할 수 있도록 출력하는 디스플레이(6)로 구성되었다.As shown in FIG. 1, the surge spring measuring device of the valve spring is described below. The valve 1 rotates to prevent uneven wear, the spring seat 2 provided on the valve 1, and the spring seat. In the valve structure consisting of a valve spring (3) seated in order to return the valve (1) to (2), it is provided in the valve spring (3) to change the volume change caused by the linear reciprocating motion of the valve (1) Strain gauge (4) measured by the change of, the amplifier refiner (5) for receiving and amplifying the current output from the strain gauge (4), and receives the amplified current from the amplifier (5) It is composed of a display 6 for outputting it for the user to identify.
상기 스프링시트(2)는 밸브(1)의 일단과 헤드블록의 바닥면에 각각 위치한 것으로 밸브(1)를 원위치로 복귀시키는 밸브스프링(3)을 안착시켜 고정하였다.The spring seat (2) is located at one end of the valve (1) and the bottom surface of the head block, respectively, was fixed by seating the valve spring (3) for returning the valve (1) to its original position.
상기 스트레인게이지(4)는 얇은 구리선으로 구성되어 밸브스프링(3)의 일단에 설치되며 밸브스프링(3)의 상하운동에 따른 길이 변화시 구리선의 길이 변화에 따른 단면적의 변호로 입력된 전류의 저항값의 변화되어 출력되도록 되어있다.The strain gauge 4 is composed of a thin copper wire and is installed at one end of the valve spring 3, and the resistance of the current inputted by the variation of the cross-sectional area according to the length change of the copper wire when the length changes due to the vertical movement of the valve spring 3 is changed. The value is changed and output.
상기 앰프리파이어(5)는 스트레인게이지(4)로 부터 출력되는 미세한 전류를 증폭하여 이를 사용자가 식별할 수 있도록 디스플레이(6)에 출력하였다.The amplifier refiner 5 amplifies the minute current output from the strain gauge 4 and outputs it to the display 6 so that the user can identify it.
이와 같이 밸브스프링(3)의 서어징을 측정하고자 할 때에는 밸브스프링(3)에 스트레인게이지(4)를 설치한 뒤에 기판을 회전시켜 밸브스프링(3)이 밸브(1)에 의해 직선 왕복운동하면, 스트레인게이지(4)에서 출력된 길이 변화에 따른 저항값을 앰프리파이어(5)에서 증폭하여 사용자가 디스플레이(6)를 통하여 이를 측정할 수 있었다.As described above, when the surge of the valve spring 3 is to be measured, the strain spring 4 is installed in the valve spring 3, and then the substrate is rotated so that the valve spring 3 linearly reciprocates by the valve 1. The amplifier 5 amplifies the resistance value according to the change in the length output from the strain gauge 4 so that the user can measure it through the display 6.
그러나 편마모를 방지하기 위해 밸브가 회전되고, 상기 밸브와 이런 현상이 나타나면 회전됨으로써 스트레인게이지의 구리선이 끊어지는 현상이 생기는데, 스트레인게이지를 재설치 하기 위해 엔진을 분해하여야 함으로 측정에 오랜 시간이 소요되는 문제점이 있었다.However, the valve is rotated to prevent uneven wear, and when this phenomenon occurs with the valve, the copper wire of the strain gage is broken, which causes a long time to measure because the engine must be disassembled to reinstall the strain gage. There was this.
따라서, 본 발명은 밸브스프링의 서어징측정시 밸브스프링의 회전을 방지하도록 하여 측정장치측 부품의 파손을 방지하고 이로부터 측정에 소요되는 시간이나 측정 손실을 줄일수 있도록 하는 것이다.Accordingly, the present invention is to prevent the rotation of the valve spring in the surge spring measurement of the valve spring to prevent damage to the components of the measuring device and to reduce the time or measurement loss required from the measurement.
이와 같이 목적을 달성하기 위한 본 발명의 특징은 헤드블록의 스프링시트에 안착되는 밸브스프링과, 상기 밸브스프링에 설치한 스트레인게이지가 밸브스프링의 길이 변화에 대한 저항값의 변위를 측정하여 앰프리파이어에 의해 전류가 증폭되어 이를 디스플레이로 출력하도록 구성된 밸브스프링 서어징측정장치를 밸브스프링에 설치하는데 있어서, 밸브스프링에 걸림홈을 형성하고, 상기 걸림홈에 밸브스프링의 회전을 방지하도록 탈착가능하게 걸림핀을 설치하며, 상기 걸림편이 삽입되어 고정되도록 스프링시트에 고정홈을 형성함으로서 이루어지는 것이다.Thus, the characteristics of the present invention for achieving the object is the amplifier spring by the valve spring seated on the spring seat of the head block, and the strain gauge installed on the valve spring measures the displacement of the resistance value with respect to the length change of the valve spring In the installation of the valve spring surging measuring device configured to amplify the current by the output to the display in the valve spring, forming a catching groove in the valve spring, the catching groove is detachably latched to prevent rotation of the valve spring By installing a pin, the locking piece is formed by forming a fixing groove in the spring sheet to be fixed.
본 발명의 밸브스프링 서어징측정장치의 스트레인게이지 설치구조를 제2도에 도시한 바에 의하여 이하에서 설명하면 다음과 같다.The strain gauge installation structure of the valve spring surging measuring apparatus of the present invention will be described below with reference to FIG.
헤드블록(11)의 스프링시트(12)에 안착되는 밸브스프링(13)과, 상기 밸브스프링(13)에 설치한 스트레인게이지(14)가 밸브스프링(13)의 길이 변화에 대한 저항값의 변위를 측정하여 앰프리파이어(15)에 의해 전류가 증폭되어 이를 사용자가 식별할 수 있도록 출력하는 디스플레이(6)로 구성함에 있어서, 밸브스프링(13)에 형성함 걸림홈(13a)에 밸브스프링(13)의 회전을 방지하도록 탈착가능하게 설치되는 걸림핀(17)과, 상기 걸림핀(17)이 삽입되도록 스프링시트(12)에 형성된 고정홈(12a)으로 구성된다.The valve spring 13 seated on the spring seat 12 of the head block 11 and the strain gauge 14 installed on the valve spring 13 are displaced in response to the change in length of the valve spring 13. In the configuration of the display 6 for measuring and measuring the current is amplified by the amplifier refiner (15) and outputs so that the user can identify, formed in the valve spring (13) valve spring ( The locking pin 17 is detachably installed to prevent rotation of the 13 and the locking groove 12a is formed in the spring sheet 12 so that the locking pin 17 is inserted.
상기 걸림핀(17)은 밸브스프링(13)이 흡배기장치인 밸브(11)를 따라 회전되지 않도록 밸브스프링(13)을 고정하는 것으로, 밸브스프링(13)의 걸림홈(13a)과 스프링시트(12)의 고정홈(12a) 사이에 삽입되어 밸브스프링(13)이 회전되는 것을 방지한다.The locking pin 17 is to fix the valve spring 13 so that the valve spring 13 does not rotate along the valve 11, which is an intake and exhaust device, and the locking groove 13a and the spring seat ( It is inserted between the fixing groove 12a of 12) to prevent the valve spring 13 from rotating.
이와 같이 구성된 상태에서 밸브스프링(13)의 서어징을 측정하고자 할 때에는 밸브스프링(13)에 스트레인게이지(14)를 설치한 뒤 기관을 회전시켜 밸브(11)에 의해 밸브스프링(13)이 직선왕복운동하면 스트레인게이지(14)에서 출력된 밸브스프링(13)의 길이 변화에 따른 저항값을 앰프리파이어(15)에서 증폭하여 사용자가 디스플레이(16)를 통하여 이를 측정한다.When measuring the surging of the valve spring 13 in this configuration, the strain spring 14 is installed in the valve spring 13 and the engine is rotated so that the valve spring 13 is straight by the valve 11. In the reciprocating motion, the resistance value according to the change in the length of the valve spring 13 output from the strain gauge 14 is amplified by the amplifier refiner 15 and the user measures it through the display 16.
이때 흡배기장치인 밸브(11)에 의해 밸브스프링(13)이 회전되고자 할 때 밸브스프링(13)이 걸림핀(17)에 의해 고정되어 스트레인게이지(14)가 끊어지는 것을 방지하는 효과가 있는 것이다.At this time, when the valve spring 13 is to be rotated by the valve 11 which is an intake and exhaust device, the valve spring 13 is fixed by the catching pin 17 to prevent the strain gauge 14 from breaking. .
이와 같이 본 발명은 밸브스프링의 서어징측정시 밸브스프링에 스트레인게이지를 고정하여 스트레인게이지의 파손을 방지함으로서 부품의 비용을 절감할 수 있으며, 스트레인게이지의 파손으로 스트레인게이지를 재설치하는 작업을 단축할 수 있도록 한 것이다.As described above, the present invention can reduce the cost of components by fixing the strain gauge to the valve spring when measuring the surge of the valve spring to prevent breakage of the strain gauge, and shorten the task of reinstalling the strain gauge due to breakage of the strain gauge. I would have to.
