摘要
以一种应用于某滑块磨床的双导程进给系统为对象,对该双导程进给系统进行了介绍;基于Workbench对滑块磨床中的y轴双导程进给系统进行了静动态特性仿真分析。分析结果表明:静态特性方面,该进给系统最大应力约为1.65 MPa,最大变形约为11μm,位于第二工作台最右端,砂轮处变形约为4.2μm;动态特性方面,该进给系统1阶固有频率约为138.34 Hz,最大振幅位于二级进给驱动部分,相较于传统滚珠丝杠进给系统具有更好的动态特性。在设计阶段对该双导程进给系统进行静动态特性分析,为进给系统的结构优化设计、指导样机生产提供了理论支撑。
A double lead rolling linear feed system applied in a special grinding machine for sliding block is introduced:its working principle and structure characteristics are elaborated,and the static and dynamic characteristics of the y axis feed system in the slider special grinder are simulated and analyzed in Workbench simulation software.The analysis results show that the maximum stress of the feed system is about 1.65 MPa in terms of static characteristics,the maximum deformation is about 11μm,located at the far right end of the second workbench,and the deformation at the grinding wheel is about 4.2μm;while in terms of dynamic characteristics,the first order natural frequency of the feed system is about 138.34 Hz,and the maximum amplitude is located in the secondary feed drive section,which has better dynamic characteristics compared with the traditional ball screw feed system.The analysis on the static and dynamic characteristics of the double lead rolling linear feed system is conducted in design stage,which provides theoretical support for structural optimization design of the feed system and guiding prototype production.
