毕业设计论文 学 院： 机械工程学院 专 业： 机械设计制造及其自动化 题 目： 焊缝自动跟踪系统设计 -焊接小车车身设计 2010年6月 摘要 随着制造业的不断发展，传统的手工焊接已不能满足现代高技术产品制造的质量、数量要求，提高焊接自动化程度已成为现代焊接工艺发展的关键问题。焊接机器人的发明使焊接自动化产生革命性的进步，它的出现极大地提高了焊接生产的自动化水平，使焊接工艺的生产效率和生产质量产生了质的飞跃。本文设计了一种能够完成焊缝自动跟踪系统的全位置爬行式焊接机器人系统。 首先，本文从整体上介绍了一种采用履带式爬行机构的全位置焊接机器人系统，详细地阐述了系统的组成和工作原理。该系统由爬行机构、焊接系统、视觉跟踪系统及控制系统组成。 其次，本文介绍了焊接机器人焊接小车部分及焊枪摆动机构的设计情况，对小车车体组成和各部分结构功能进行了说明和分析。 最后，对焊接机器人系统中的送丝机构做了系统分析，介绍了其原理及组成，并对部分部件（送丝轮及其轮轴）做了设计和计算。 关键词：焊接机器人; 焊缝跟踪 ;焊接小车; 送丝机构 Abstract With the continuous development of the manufacturing sector, the traditional hand soldering can not meet the modern high-tech product manufacturing quality and quantity requirements, improve welding automation have become key issues in the development of welding technology. The invention of welding robot welding revolutionary advances in automation, which greatly improves the appearance of the production level of automation of welding to welding productivity and product quality produced a qualitative leap. This paper designs an automatic seam tracking system can complete the whole welding robot crawling position. First, the paper introduces an overall crawler crawling bodies all position welding robot system, the system described in detail the composition and work principle. The system consists of crawling bodies, welding systems, visual tracking and control system. Second, the article describes some of the welding robot and welding torch welding car body design swing situation, car body components and their structure and function are described and analyzed. Finally, robotic welding wire feeding system has done a systematic analysis, description and composition of its principles, and some parts (wire wheel and axle) to do the design and calculation. Key words: welding robot; seam tracking; welding carriage; wire feeder 第1章 绪论 1.1课题研究的目的及意义 焊接是制造业中最
