为实现超声振动钻削加工，需设计超声振动主轴系统。而主轴系统中声振部件是最关键的部件。本文首先提出了一套用于微细孔加工的轴向超声振动钻床主轴的关键部件的设计方案，通过分析超声振动钻削主轴的基本工作原理，确定了主轴关键部件的结构选择和设计方法，进一步对主轴关键部件的连接进行改进。随后对主轴关键部件建立动力学模型，并应用Ansys Workbench软件对其进行了动力学分析，得到了关键部件的模态和谐响应特性，动力学分析验证了设计的可行性，最后通过钻削实验实现了难加工材料的微细孔振动钻削。

In order to achieve ultrasonic vibration machining, an ultrasonic vibration spindle system was developed, and the acoustic components are the key part of the system. In this paper,a design scheme for the key components of ul-trasonic vibration assisted drilling spindle system was proposed,which can be used for micro-hole machining. By study-ing the basic principle of ultrasonic vibration assisted drilling spindle, the structure and the design method of the key components were determined. Moreover,the connections among the key components of spindle were improved. To veri-fied the feasibility of the design,a dynamic model of key components has been build. Through the dynamic analysis by ANSYS Workbench, the results of model and harmonic response were acquired. The drilling experiments showed that processing micro-hole in the difficult-to-machine material can be achieved with ultrasonic vibration drilling technology.
