加工中心自动换刀系统设计说明书 毕业论文 .doc

摘要 加工中心是现代机械加工中用得最多的设备之一，而自动换刀装置作为加工中心的核心部件，一直处在不断改进之中。本课题 Abstract Processing Center is a modern mechanical processing equipment used in one of the largest and automatic tool change device as the core parts processing center, has been in the continuous improvement of. The topics designed a small knife processing center for devices and automatic tool change. The design is divided into two parts. First of all, the main view of the current machine, commonly used for several types of knives (knives drum disc library, the chain knife, knife lattice cassette library, etc.) a comparative analysis, the final choice of the chain knife structure, choice of servo motor Driver, a worm worm deceleration devices, and completed the chain and sprocket of the choice of design and calculation. In addition, the choice of single-claw manipulator arms structure, its movement made a detailed analysis will eventually ATC campaign for the decomposition of the telescopic arm, hand-stretching and rotating the three movements. All the hydraulic system used to control. A reasonable choice of hydraulic cylinders, to map out plans of the hydraulic control systems, mechanical hand movements schematics, basically completed the installation of automatic tool change the design work. Keywords：The servo motor actuates; Chain knife storehouse; The manipulator trades the knife; The hydraulic system controls目录 目 录 摘 要 I Abstract Ⅲ 1 绪 论 1.1 本课题的来源、目的及意义 (1) 1.1.1 课题的来源……………………………………………………….....(1) 1.1.2 本课题研究的目的……………………………………………….....(1) 1.1.3 本课题研究的意义………………………………………………….(1) 1.2 课题背景及国内外研究现状 (2) 1.3 本课题研究的主要内容 (3) 2 刀库及换刀机构总体结构设计 2.1 刀库的结构设计 (3) 2.1.1 方案分析比较…………………………………………………….....(3) 2.1.2 刀库容量的确定………………………………………………….....(6) 2.1.3 刀库选刀方式的确定…………………………………………….....(6) 2.1.4 刀库的设计及计算……………………………………………….....(6) 2.2 自动换刀装置设计 (13) 2.2.1 方案分析比较……………………………………………………...(13) 2.2.2 机械手自动换刀工作流程设计…………………………………...(13) 2.2.3 换刀机械手结构设计……………………………………………...(22) 2.2.4 换刀手手臂和手爪结构设计……………………………………...(23) 2.2.5 液压
