| description | To provide an electric/hydraulic dual use cylinder device that combines both hydraulic driving for high driving force and electric driving capable of high speed and/or accurate speed control, has a simple structure and high durability, and is easy to maintain.SOLUTION: An electric/hydraulic dual use cylinder device includes a cylinder tube 10 having a cylindrical shape, a first piston 20 that is in the cylinder tube 10 and is electrically driven, a second piston 30 that is hydraulically driven, and a piston rod 40 that transmits force of both the first piston 20 and the second piston 30. The first piston 20 is driven by rotating a ball screw 70, which is screwed into a female screw provided on an axial center, with a motor 80, and has a rotation stop mechanism comprising a convex key 50 that is provided on the outer periphery of the first piston 20 and a long hole 60 that is engaged with the key 50 and is provided to penetrate the cylinder tube 10.SELECTED DRAWING: Figure 1
【課題】高駆動力の液圧駆動と、速度の速いおよび／または正確な速度制御の可能な電動駆動の両方を兼ね備えた、構造が単純で、耐久性が高く、メンテナンスの容易な、電動／液圧両用シリンダ装置を提供する。【解決手段】円筒形のシリンダチューブ１０と、シリンダチューブ１０内にあって、電動駆動される第１ピストン２０と、液圧駆動される第２ピストン３０と、第１ピストン２０と第２ピストン３０との両方の力を伝達するピストンロッド４０とを備え、第１ピストン２０は軸心に設けられた雌ねじに螺合するボールねじ７０をモータ８０で回転することによって駆動され、第１ピストン２０の外周に設けられた凸状のキー５０と、キー５０と係合し、シリンダチューブ１０に貫通して設けられた長穴６０とよりなる廻り止め機構を有する。【選択図】図１ |
