| 摘 要： | 微夹钳是微装配与微操作过程中直接与被操作对象相接触的末端执行器，对微装配与微操作任务的完成起着决定性作用．介绍了一种采用压电致动的微夹钳的工作原理、结构组成及实验原型，该微夹钳采用一种基于双边和单边直圆柔性铰链的单片柔顺机构实现微位移传递／放大功能，同时实现微夹钳夹爪平行移动．针对本文研究和开发的一种微夹钳的原型建立了实验装置并进行了开环位移特性测试．实验结果表明，微夹钳的夹爪能够实现平行移动，夹爪的输出位移与输入位移呈线性关系，且微夹钳单边夹爪输出位移最大可达150μm．

| Abstract: | Microgrippers,which directly contact the operated object as the end-effectors of the microassembly and micromanipulation systems,play a crucial role in microassembly and micromanipulation.In this paper,the operation principle,structure configuration and experimental prototype of a piezoelectrically driven microgripper were introduced.A monolithic compliant mechanism based on single-notch right-circular flexure hinges and double-notch right-circular flexure hinges was used in the microgripper to amplify/tran... |
