苹果装箱机械手设计
中文摘要
本课题最终目的在于研制一套自动装箱机械手用于苹果自动生产线取代人工装箱工作，以实现成型工序参数的稳定性。设计了一种苹果自动装箱机械手，利用步进电动机带动手臂进行上下移动和水平垂直旋转，通过气压驱动机械手抓取和松放，能够实现全自动装箱放各种型式和材料的苹果。本次设计的苹果自动装箱机械手由底座、传送机构、臂部升降机构、臂部摆动机构、吸盘等构成。
本次设计首先，通过对苹果自动装箱机械手结构及原理进行分析，在此分析基础上提出了总体结构方案；接着，对主要技术参数进行了计算选择；然后，对各主要零部件进行了设计与校核；最后，通过AutoCAD制图软件绘制了苹果自动装箱机械手装配图及主要零部件图。
通过本次设计，巩固了大学所学专业知识，如：机械原理、机械设计、材料力学、公差与互换性理论、机械制图等；掌握了普通机械产品的设计方法并能够熟练使用AutoCAD制图软件，对今后的工作于生活具有极大意义。

Title Apple packing manipulator design
Abstract
The ultimate goal of this project is to develop a set of automatic packing machine for automatic production line of apple to replace the manual packing, in order to achieve the stability of the forming process parameters. An apple automatic packing manipulator is designed, using step motor drive the arm of under movement andvertical rotation, through the air pressure drive manipulator and release, can realize the automatic packing forvarious types and materials of apple. The design of Apple's automatic packing machine hand by the base, the transmission mechanism, the arm of the lifting mechanism, the arm swing mechanism, sucker, etc..
This design first, through apple automatic packing machine for the structure principle and analysis, this analysis is proposed based on the overall structure of the program; then, the main technical parameterswere calculated to select; then, of the main partswere designed and checked. Finally, through the AutoCAD drawing software drawn apple automatic packing machine for assembly and major parts of the map.
Through the design, the consolidation of the University of the professional knowledge, such as: mechanical principles, mechanical design, mechanics of materials, tolerance and interchangeability theories, mechanical drawing; master the design method of general machinery products and be able to skillfully use AutoCAD drawing software, for the futurework in life is of great significance.
