Here mainly includes: Z axis transmission system design, the frame work system design, liquid medium circulation system. The graduation design on the design of the basic skills training, enhancing the analysis and to solve engineering problems, and create a certain condition for general mechanical design. The structure is mainly produced by the motor power through the coupling will need to transfer the power to the screw rod, the screw rod drives the screw rod nut, which drives the motion machine device, improve labor productivity and automation level of production. But also show its superiority, there are broad prospects for the development. The research of this thesis: (1) a small overall structure design of high-speed electric spark machine tool. (2) analysis of small hole machine tool working performance of high speed electric spark hit. (3) the choice of motor. (4) transmission system, execution unit and a high speed EDM drilling holes on the machine. (5) the design of components for the design calculation and check. (6) the use of computer aided design, 3D modeling on Design of parts. (7) to draw the assembly drawing and parts assembly diagram and parts diagram design. Keywords: high speed EDM drilling holes on the machine, coupling, ball screw 目 录 目 录 VI 1　概述 9 1.1 电火花加工前言 9 1.2 电火花加工工作原理 9 1.3 电火花加工特性 9 1.4 电火花加工主要特点 10 2 高速电火花打小孔机床总体设计 12 2.1总体概述 12 2.2 技术参数 12 3 高速电火花打小孔机床 Z轴机械结构设计 13 3.1 确定脉冲当量 13 3.2滚珠丝杠螺母副的计算和选型 13 3.2.1 精度的选择 13 3.2.2丝杠导程的确定 13 3.2.3 最大工作载荷的计算 13 3.2.4 最大动载荷的计算 14
