摘要
微夹持器是微装配系统的关键部件,设计了一种以柔性铰链为基础的二级位移放大机构的夹持器,该夹持器由压电陶瓷驱动。计算了夹持器的放大倍数和柔性铰链的节点应力,并对夹持器的最大张合量、放大倍数、夹持力和刚度进行有限元仿真分析。分析结果表明:夹持器的结构设计满足实际应用要求,对实现微小零件的自动装配有实际意义。
As micro-gripper is a key component of micro-assembly system, a gripper with two grades displacement isdesigned based on flexible hinges, which is actuated by piezoelectric ceramics. Then, its magnification and node stress is calculated, the finite element simulation analysis on maximum gripping displacement, magnification, gripping force and stiffness was carried out. The results show that the structure design of gripper can meet actual application requirements and have practical significance for achieving the automatic assembly of small parts.
