(300X300)方台面数控回转工作台设计 摘要当今世界电子技术迅速发展，微处理器、微型计算机在各技术领域得到了广泛应用，对各领域技术的发展起到了极大的推动作用。一个较完善的机电一体化系统，应包含以下几个基本要素：机械本体、动力与驱动部分、执行机构、传感测试部分、控制及信息处理部分。机电一体化是系统技术、计算机与信息处理技术、自动控制技术、检测传感技术、伺服传动技术和机械技术等多学科技术领域综合交叉的技术密集型系统工程。新一代的CNC系统这类典型机电一体化产品正朝着高性能、智能化、系统化以及轻量、微型化方向发展。关键字：机电一体化的基础 基本组成要素 特点 发展趋势Abstract Now the world electronic technology rapidly expand, the microprocessor, the microcomputer obtain the widespread application in various area of technology, to various domains technology development enormous promotion effect. A perfect integration of machinery system, should contain the following several base elements: Basic machine, power and actuation part, implementing agency, sensing measurement component, control and information processing part. The integration of machinery is the system technology, the computer and the information processing and management technology, the automatic control technology, the examination sensing technology, the servo drive technology and the mechanical skill and so on multi-disciplinary area of technology synthesis overlapping technology-intensive systems engineering. New generations CNC system this kind of model integration of machinery product toward the high performance, the intellectualization, the systematization as well as the featherweight, the microminiaturized direction develops. key words: Integration of machinery foundation basic component elements characteristic trend of development. 目录 课程设计的内容和要求 ……………………………………… 3 系统的总体方案设计 ………………………………………… 4 机械部分设计 …………………………………………… 5 3.1 脉冲当量和传动比的确定 …………………………………… 5 3.2工作台外形尺寸及重量初步估算………………………………… 5 3.3 传动系统等效转矩惯量计算…………………………………… 6 3.4 工作载荷分析及计算…………………………………………… 6 3.5 滚珠丝杠螺母副的选型和校核………………………………… 8 3.6 导轨的选型和计算……………………………………………… 11 3.7 驱动电机的选择………………………………………………… 11 第四章 数控系统设计………………………………………………… 15 4.1 控制系统硬件的基本组成………………………………… 15 4.2 接口程序初始化及步进电机控制程序………………………… 17 4.3 直线圆弧插补程序设计………………………………………… 19 参考文献 ………………………………………………………………… 25 第一章 课程设计的内容
