摘要 本次的臂式焊接变位机结构设计，在设计焊接上机械臂自由度的一个臂式焊接变位机结构，在工业上实现焊接上机械臂型的灵活运转变位的机械臂，它基本的结构形式是通过焊接上机械臂转动来实现的，能够到达一定的空间上的一个任意的位置，实现对工业上的物件进行准确的焊接上的转移功能。通过本次设计的要求和查阅相关的设计资料，结合现有的市场上的机械臂等各方面的设计因素，确定了本次设计的机械臂一个合理的总体设计的方案，在提出的方案上通过相关的技术分析和参数的计算等，在查阅先关的文献后，确定本次设计的臂式焊接变位机结构设计的手臂、指尖夹紧焊料的结构形式等参数的标准化设计。在此次提出的设计方案的基础上，通过对实际使用的臂式焊接变位机进行采样、结构分析、参数化的计算、对设计的结构中重要部件进行校验，最后确定了各设计的部件在结构上的尺寸等。 设计中通过软件进行机构的方案设计，根据本次设计的相关的尺寸的大小，用软件绘制出臂式焊接变位机结构设计的草图，并且通过导出后绘制出CAD相应的设计结构工程图。并能够实现对焊料的迅速准确转移等目的，最终实现焊接上的动作。 关键词：焊接上机械臂转动、机械臂、机器臂 Abstract The structural desig
