선박용 밸브스핀들의 런-아웃 검사장치{valve spindel's run-out inspection device for ship}Valve spindel's run-out inspection device for ship

본 발명은 내연기관의 흡배기용 밸브스핀들에 대한 동심도와 직각도 및 직진도를 검사하는 런-아웃 검사장치에 관한 것이다.The present invention relates to a run-out inspection apparatus for inspecting concentricity, squareness and straightness of the valve spindle for intake and exhaust of an internal combustion engine.

선박과 같은 내연기관의 흡배기용 밸브스핀들은 원판형의 헤드부에 직각방향으로 길이가 긴 스핀들이 형성된 형태로 통상 긴 환봉형태의 소재를 업셋(up-set) 단조방법으로 헤드를 성형하여 완성된다.Valve spins for intake and exhaust of internal combustion engines, such as ships, are formed by forming long spindles at right angles in the disk-shaped heads, which are usually formed by forming the heads in an up-set forging method. .

밸브스핀들은 헤드와 스핀들의 동심도와 직각도 및 직진도가 불량할 경우 헤드가 밸브가이드와 접촉이 불량하여 흡배기 가스가 누출된다거나 내연기관의 파손을 초래하는 원인이 된다.The valve spindles may cause a poor contact with the valve guide due to poor concentricity, right angle and straightness of the head and spindle, resulting in intake and exhaust gas leakage or damage to the internal combustion engine.

따라서 밸브스핀들은 연마가공 전에 밸브스핀들의 동심도, 직각도 및 직진도 등을 검사하여 교정작업을 거친 후 최종연마작업을 수행하고, 최종연마작업 후에는 제품의 완성도를 검사한다.Therefore, the valve spins are inspected for concentricity, perpendicularity, and straightness of the valve spins before grinding, to carry out the final polishing operation after the calibration work, and to check the completeness of the product after the final polishing work.

종래 밸브스핀들의 런-아웃검사는 정반상에 구비된 V블록상면에 밸브스핀들을 거치하고 수작업으로 밸브스핀들을 회전시키면서 아날로그 인디케이터로 밸브헤드의 동심도와 스핀들의 직각도 및 직진도를 계측하였으나 측정데이터의 계량화가 어려워 불량의 통계적 관리가 곤란하고 휴먼 에러의 발생으로 측정자의 변동시 측정치가 변동될 수 있었고, 수작업으로 밸브스핀들을 회전시킴에 따라 정확하게 360°를 회전시키기 어렵다는 문제점과 함께 측정작업에 많은 시간이 소요된다는 문제점이 있었다.In the run-out inspection of the conventional valve spindles, the valve spindles are mounted on the upper surface of the V block and the valve spindles are manually rotated to measure concentricity and straightness and straightness of the valve head with an analog indicator. It is difficult to quantify the data, making it difficult for statistical management of defects, and the measurement value can be changed when the measurement changes by the human error.It is difficult to rotate 360 ° accurately by rotating the valve spindle by hand. There was a problem that it takes.

In addition to this, it is possible to drastically reduce the time required for measurement, thereby improving the productivity of the valve spindle.
