摘 要 数控技术是先进制造技术的核心，是制造业实现自动化、网络化、柔性化、集成化的基础。数控装备的整体水平标志着一个国家工业现代化水平和综合国力的强弱ABSTRACT Numerical control technology is the core of advanced manufacturing technology, are manufacturing realize automation, network, flexibility, integration foundation.Machining center is a sword with knife library can automatically change tool repository is more process of workpiece of numerical control machine.This paper introduces is processing center library design tools. Tool storage adopts the chain structure, it is respectively by a guide wheel, regulate the wheel, the drive wheels composition, dao database is for 40 to choose way, using any sword. Tool storage kinematic characteristics is, time short intermittent movement: starting and stopping no impact on the smooth, accurate positioning and arbitrary way and choosing tools velocity is not high Key words：Processing center Automatic tool changer Tool storage 目 录 摘要 …………………………………………………………………………………………1 Abstract ……………………………………………………………………………………1 目录……………………………………………………………………………………………1 第1章 绪论 …………………………………………………………………………………2 1.1数控机床的发展现状 …………………………………………………………………2 1.1.1国际数控机床的发展现状 …………………………………………………………2 1.1.2 国内控机床的发展状况……………………………………………………………3 1.2加工中心…………………………………………………………………………………4 1.2.1加工中心用途和特点………………………………………………………………5 1.2.2加工中心的组成及其工作原理……………………………………………………6 第二章 加工中心刀库方案设计………………………………………………………………7 2.1 加工中心刀库换刀系统概述…………………………………………………………7 2.2 刀库方案设计 ………………………………………………………………………8 2.2.1 刀库方案的确定…………………………………………………………………8 2.3总体方案设计 ………………………………………………………………………8 2.3.1刀库的总体设计…………………………………………………………………8 2.3.2确定刀具的选择方式 …………………………………………………………8 2.3.3刀库的驱动系统…………………………………………………………………10 2.3.4刀库运动的定位装 …………………………………………………………10 2.3.5刀库运动中力的传输……………………………………………………………11 第三章 参数的确定…………………………………………………………………………12 3.1电机的选用……………………………………………………………………………12 3.2蜗轮及蜗杆的选用与校核……………………………………………………………12 3.3刀库驱动转矩的校核…………………………………………………………………15 3.4 轴承的选用 ………………………………………………………………………15 3. 4. 1
