夹紧气缸直接利用气动驱动式夹紧元件或通过运动机构，对工件执行保持或夹紧操作。 在非工作状态下，夹紧元件会从作业区域退出。 得益于其运动学特性，夹紧气缸能够以较低的能量输入实现非常高的夹持力。 为满足不同夹紧需求，Festo 开发有膜片式夹紧气缸、直线/回转式夹紧气缸和铰链式气缸等多种产品。
In welding and clamping processes, confirmation signals protect quality and safety. Add cylinder sensors as pneumatic actuator limit switches. These cylinder end position sensors, often used as limit switches for pneumatic cylinders, detect the piston magnet—typically via a reed switch for pneumatic cylinder—and report the clamp position clearly. They act as pneumatic cylinder end-of-stroke sensors and a dependable cylinder limit switch for sequencing.
