南 京 工 程 学 院毕业设计说明书(论文)作 者: 罗 毅 学 号: 201080426 系 部: 机械工程学院 专 业: 机械电子专业 题 目: CK6125 型半闭环系统数控车床设计 指导者: 李雪 讲师 评阅者: 2012 年 06 月 南 京摘 要CK6125 数控车床由主传动系统,进给系统和控制系统三部分组成。设计中首先进行总体方案的确定,画出简易的传动系统图,根据给定的设计参数对主传动和进给系统中的主要传动件进行了校验计算。进给系统由步进电机驱动滚珠丝杠实现进给。控制系统是由 CPU、键盘,显示,接口电路,脉冲分配器和电机驱动部分组成。CK6125 通过单片机反馈补偿实现半闭环控制。最后进了技术经济分析得出设计生产该产品是经济合理的。关键词:数控 车床 设计Half a closed loop system of CK6125 CNC lathe designAbstractCK6125 CNC lathe is made up by three parts ,that is main transmission system, feeding system and control system . In the design scheme for the first, draw the simple transmission system graph, according to the design parameters of a transmission and the main transmission system into the calibration calculation. Feeding system by stepping motor drive the ball screw realize feed.Control system consists of CPU, keyboard, display, interface circuit, pulse distributors and motor driving part. Through the feedback compensation of the single-chip microcomputer CK6125 realize half closed loop control .Finally into the technical and economic analysis of the design and production of the product is reasonable in economy .Keywords: the numerical control lathe design目 录第一章 前 言.............................................................................................................1第二章 总体方案设计...................................................................................................22.1 设计参数...............................................................................................................22.2 总体方案的确定..................
