广西工学院 毕业设计（论文）说明书 课题名称 C630-1D车床的数控改造 ——横向进给运动的设计 系 别 机械工程系 专 业 机械工程及其自动化（数控技术） 班 级 机自Y073 学 号 200700104038 姓 名 潘 子 龙 指导教师 李 健 教 授 2011年 1月 10日摘要众所周知，制造业是国民经济的基础产业和支柱产业，是推动国家技术进步的力量。我国制造业较落后，想要改变此现状就必须提高制造业装备水平，特别是机床的数控化率。数控机床是属于高新技术集成的机电一体化机械加工设备，受到世界各工业发达国家的高度重视。成为当今世界机械加工设备中最引人注目的产品，但其价格昂贵。因此，普通车床的数控化改造成为热点。本次设计是对普通车床C6的数控化改造。主要包括:主传动系统的改造、进给系统的改造、进给系统的改造。进给系统改造这次毕业设计对设计工作的基本技能的训练，提高了分析和解决工程技术问题的能力，并为进行一般机械的设计创造了一定条件数控改造主要传动系统的机械改造。由于对经济型数控机床的加工精度要求不高，为简化结构、降低成本。通过控制横进给系统，保证改造后的车床具有定位、直线插补、圆弧插补、暂停等功能。为实现机床所要求的，采用步进电机经再传动丝杠；为保证一定的传动精度和平稳性，尽量减小摩擦力，选用滚珠丝杠螺母副。关键词：车床 数控改造滚珠丝杠 Abstract As we all know, manufacturing is the basic of economy industries and pillar industries, is the power to promote the progress of technological of the State. Chinas manufacturing industry has fallen behind，if we want to change this situation we must improve the level of equipment manufacturing industry, especially in CNC machine tools rate. High-tech CNC machine tools are integrated mechatronics mechanical processing equipment, the worlds industrialized countries are highly valued of it. It has become the worlds most remarkable mechanical processing equipment products, but the price is very expensive. Therefore, the lathe’s Transformation of NC has become a hot. This design is about the common Lathe C630-1D transformation of NC. Main tasks are: the transformation of the main transmission system, the transformation of the vertical feeding system, horizontal feed system reform. While I was mainly aim at the lateral feeding system mechanical transformation. The graduation project on the design of the basic skills training has improved the analysis and the ability to solve engineering problems, and create a
