摘　　要：针对传统多轴数控电火花高速小孔机结构布局不合理、加工精度不稳定、占地面积大等问题,设计了专用于叶片气膜孔加工的数控电火花小孔机床。结果表明:通过有限元分析优化设计,机床具有更优良的静态机械性能;通过紧凑型总体布局设计和合理化结构设计,减少机床占地空间;通过配置刀库、导向器库、扶丝器、卡盘等自动化装置,减少人工操作、短缩加工辅助时间,适用于自动化生产线。Aiming at the shortcomings of the traditional multi-axis CNC EDM high-speed small hole machine,such as unreasonable structure layout,unstable machining accuracy and large occupied space,a CNC EDM small hole machine dedicated to blade gas film hole processing was designed.The research results show that the machine tool has better static mechanical properties through finite element analysis.The compact overall layout design and rationalization structure design help to reduce the space occupied by machine tools.The automatic devices such as the configuration of tool library,guide library,wire holder,chuck help to reduce manual operation and shorten the auxiliary processing time,which can be used in automatic production line.
