设计简介
摘要：在当今大规模制造业中，企业为提高生产效率，保障产品质量，普遍重视生产过程的自动化程度，工业机器人作为自动化生产线上的重要成员，逐渐被企业所认同并采用。工业机器人的技术水平和应用程度在一定程度上反映了一个国家工业自动化的水平，。工业机器人的技术水平和应用程度在一定程度上反映了一个国家工业自动化的水平，目前，工业机器人主要承担着焊接、喷涂、搬运以及堆垛等重复性并且劳动强度极大的工作，工作方式一般采取示教再现的方式。
本设计介绍了关于工业机器人的一些基本常识和原理，包括工业机器人的组成、分类、主要技术性能参数和工业机器人的运动分析，并参考通用型工业六自由度机器人的结构。根据对工业六自由度机器人的总体结构及传动系统的分析和探讨，进行三自由度工业机器人的结构设计。关键在于三轴（臂）的传动系统的设计以及整体的结构设计，避免运动的干涉，在本次设计中主要负责第一臂与底座的结构设计及其传动原理，对第一臂与底座的各零部件的结构设计。

Abstract ： In the modern large-scale manufacturing industry, enterprises pay more attention on the automation degree of the production process in order to enhance the production efficiency, and guarantee the product quality. As an important part of the automation production line, industrial robots are gradually approved and adopted by enterprises. The technique level and the application degree of industrial robots reflect the national level of the industrial automation to some extent, currently, industrial robots mainly undertake the jops of welding, spraying, transporting and stowing etc. , which are usually done repeatedly and take high work strength, and most of these robots work in playback way.
The Design of industrial robots on some basic common sense and principles, including the composition of industrial robots, classification, main technical performance parameters and the movement of industrial robots, with reference to general-purpose industrial 6-DOF robot's structure, conduct three degrees of freedom industrial robot structural design, based on the industry overall structure of six degrees of freedom robot and transmission system analysis and discussion of the 3-DOF industrial robot for structural design. The key lies in the fact that three axis (arm) transmission system design and the whole structure design, avoid the interference in the sports, mainly responsible for the design of the arm and base structure design and its transmission principle of first arm and the base of the parts of the structure design.
