中走丝线切割机床工作台进给系统设计方案的研究

摘要

在采用滚动直线导轨的基础上，对中走丝线切割机床DK7732的工作台进给系统进行了设计。根据机床工作台速度从静止加速至快速移动速度，为满足工作台性能的要求，对工作台进给系统电机转速、驱动扭矩、惯量匹配作了详细的计算。另外，对工作台滚珠丝杠螺母进给传动系统结构进行了设计和分析。%Adopting rolling linear guide, the workbench feeding system of the medium⁃speed wire cut electrical discharge machi⁃ning DK7732 was designed. According to the character of accelerating speed from motionless to the fast moving speed, to meet the re⁃quirements of workbench performance, the motor speed of workbench feeding system, driving torque, inertia matching were calculated in detail. On the other hand, the ball screw nut feeding drive system structure of the workbench was designed and analyzed.
