摘　　要：简要介绍了PCB高速钻铣床机械结构,该结构采用龙门框架式总体布局,工作台床身选用箱形铸件结构,其上安装有台面、运动部件等;主轴采用高转速电主轴,额定转速8000为rad/min;采用丝杆螺母实现传动和换向,保证运动传递平稳和结构的紧凑;采用导轨副实现导向和承载,保证各运动部件的相对位置和精度;采用继电器-接触器电气控制系统,基于运动控制卡的开放式数控系统,该研究对数控设备设计制造有一定借鉴价值。The mechanical structure of PCB high-speed drilling and milling machine is briefly introduced. The structure adopts the overall layout of the gantry frame. The bed of the workbench is made of box-shaped casting structure, and the table top and moving parts are installed on it. The spindle adopts highspeed electric spindle with rated speed of 8000. Rad/min;screw and nut for transmission and commutation, to ensure smooth motion transmission and compact structure;guide and load to achieve the relative position and accuracy of the moving parts;using relaycontactor electrical control system, Based on the open CNC system of motion control card, this research has certain reference value for the design and manufacture of numerical control equipment.
