Abstract
Description
Claims (1)
- 실린더내부에 제 1 및 제 2 프리피스톤을 축방향에 인접하여 전후운동 자유롭게 배치하고, 상기 실린더내에 상기 제 1, 제 2 프리피스톤에 의하여 전부, 중부 및 후부의 실린더실(R1, R2, R3)을 구획하며, 상기 전부실린더실(R1), 중부실린더실(R2) 및 후부실린더실(R3)에 에어원으로부터 에어를 선택적으로 도입할 수 있는 유로를 형성하고, 에어원으로부터의 에어가 제 1 프리피스톤과 제 2 프리피스톤의 사이의 중부실린더실에 도입되었을 때에는 제 1, 제 2 프리피스톤이 서로 떨어지는 방향으로 이동하며, 에어원으로부터의 에어가 제 2 프리피스톤의 전부실린더실 및 제 1 프리피스톤의 후부실린더실에 도입되었을 때는 제 1, 제 2 프리피스톤이 동시에 접근하는 방향으로 이동하고, 이러한 제 2 프리피스톤의 왕복이동에 의하여 상기 제 2 프리피스톤의 전방에 설치된 공구지지샤프트를 왕복운동시켜서 동일 샤프트에 부착한 공구에 의해 워크에 가공을 실시하는 왕복운동공구이고,상기 제 1 프리피스톤의 후방에는 상기 공구지지샤프트와 거의 동일 직경의 샤프트부를 설치하여 상기 제 1 프리피스톤과 제 2 프리피스톤의 질량을 대략 동등하게, 또한 에어원으로부터의 에어압이 제 1 프리피스톤, 제 2 프리피스톤에 동시에 작용하는 수압면적을 동등하게 한 것을 특징으로 하는 왕복운동공구의 방진구조.
