摘　　要：快速车削能够实现复杂面形零件的精密高效加工,在分析快速车削加工特点的基础上,设计了"压电陶瓷+柔性铰链"结构形式的快速刀具驱动装置;进行了柔性铰链的参数分析、结构设计和静力学分析,并采用有限元仿真方法分析了装置的刚度和振动模态;通过试验对快速刀具驱动装置进行了性能测试,结果表明所设计的快速刀具驱动装置具有较高的分辨率、跟踪精度和工作频响,能够作为超精密快速车削加工的快速进刀装置。Fast turning is capable of machining the components with complex shape accurately and efficiently. Based on the analysis of machining characteristics of fast turning, a kind of fast feed device is developed which is driven by piezoelectric actuator and flexible-hinge. The dimension parameter, the structure design and the statics characteristic of flexible-hinge are analyzed. Moreover, the stiffness and the vibratory modality are simulated by using the finite-element method. On the basis of above work, the performance of fast tool drive is tested. The result shows that the developed device take on high resolution, good tracking accuracy and high response, and it can act as fast feed device in uhra-precision fast turning.
