1、 毕业设计(论文)毕业设计(论文) 题目:题目:机床的数控化改造分析 专 业: 机械设计制造及其自动化 年 级: 2009 级 学 校: 汽修工作站 学 号: 姓 名: 指导教师: 时 间: 2011 年 11 月 I 摘要 本文介绍了机床数控化的改造,主要是对原有机床的结构进行创造性的设 计,最终使机床达到比较理想的状态。传统机床存在着一些弱点,如刚性不足、 抗振性差、热变形大、滑动面的摩擦阻力大及传动元件之间存在间隙等,难以胜 任数控机床对加工精度、表面质量、生产率以及使用寿命等要求。现代化的数控 技术,特别是加工中心,无论是其支承部件、主传动系统、进给传动系统、刀具 系统、 辅助功能等部
2、件结构, 在其整体布局、 外部造型等都已经发生了很大变化, 已经形成了数控机床的独特机械结构。 目前机床数控化改造技术已经日趋成熟, 专用化的机床数控改造系统所具备 的性能和功能一般均能满足机床的常规加工要求。 本文主要介绍了机床的数控化 改造,具有一定的借鉴作用。 关键词:专用机床、机床改造、机床、 PLC II Abstract This article describes the transformation of CNC machine tools, machine tool is mainly the structure of the original creative design
3、, and ultimately enable the machine to achieve the ideal state. There are some weaknesses of traditional machine tools, such as the lack of rigidity, vibration, poor, hot deformation, the sliding surface of the friction and drive a large gap between the components, etc., could not do the CNC machine
4、 tools for machining accuracy, surface quality, productivity and service life requirements. Modern digital technology, especially processing center, whether it is the supporting parts, the main transmission system, the feed drive system, tool systems, auxiliary functions and other parts of the struc
5、ture, or the overall layout, exterior styling, great changes have taken place and so has CNC machine tools to form a unique plant mechanical structure. Transformation of the current CNC technology has matured, dedicated CNC transformation of the system have the performance and functionality of conventional machine tools are capable to meet the processing requirements. This paper describes the transformation of CNC machine tools, has a certain reference.
