加工中心自动换刀装置结构设计 [摘要] 本论文完成的是立式加工中心盘式刀库的传动设计、结构设计以及机械手部分的传动设计、结构设计。盘式刀库在数控加工中心上应用非常广泛，其换刀过程简单，总体结构简单、紧凑，定位精度高。刀库传动部分采用蜗轮蜗杆减速装置，可提高输出轴的传动平稳性能，即提高刀盘的运转平稳性。刀库满载装刀16把，采用单环排列方式放置。本次设计中的机械手采用单臂双手式机械手，可以同时完成插刀和拔刀动作，结构简单，换刀时间短。机械手传动部分采用一个液压升降缸和液压回转缸带动花键轴，进而带动机械手的运动。 [关键词Automatic tool changer structural design of machining centers Abstract what finished in this paper is drive design, structural design and the power transmission parts design of disc tool magazine in vertical machining center. This tool magazine is widely applied in NC machining center. And the process of changing tools is simple, short change time , high precision, simple and compact of structure, reliable, easy maintenanced and low cost. The transmission part of this tool magazine adopts gear reducer. The design of worm gearbox device can improve the stationarity of output shaft, namely, increasing the operation stability and smooth transmission properties of tool magazine.Transmission device of tool magazine adopts a adjusting sleeve to eliminate the transmission clearance of worm.This tool magazine can load 16 cutting tools which are arranged with monocylic and according to the principle of nearby to choose the right tool. The manipulator of this design is the manipulator with one arm and pair of hands.The advantage of this manipulator is that it can complete the action of inserting tool and pulling out the tool at the same time,simple structure and short change time. Mechanical transmission part adopts a hydraulic lift cylinder and hydraulic cylinder drives the spline shaft rotation, thus drive the motion of the manipulator. Key words Vertical machining center; Disc tool magazine; Manipulator; Automatic Tool Changer  毕业论文﹙设计﹚任务书 一、毕业设计题目 加工中心自动换刀装置结构设计 二、毕业设计工作自_ 2012 年__11_ 月__19 _日 起至 2013 _年 6 月_10 _日止 三、毕业设计进行地点: 校 内 四、毕业设计内容要求： 随着机械加工业的发展，制造行业对于带有自动换刀系统的高效高性能加工中心的需求量越来越大。本设计主要任务是进行加工中心自动换刀装置结构设计： 1、查阅有关自动换刀系统方面的
