摘　　要：对焊接机器人工作站管管相贯的焊接坡口模型进行了计算分析。为保证管管相贯的焊接坡口多层多道焊接工艺的可行性,相贯坡口需要在数控切割机上进行切割加工。建立了小管端部坡口的数学模型,数学模型包括小管管端内径与大管相贯的空间曲线上的坡口角以及马鞍形空间曲线族。根据以上计算结果生成离散点,在三维软件SolidWorks里拟合生成坡口模型。此三维模型作为小管管端的切割源文件。实验达到了预期目的,为焊接机器人工作站焊接提供了保证。Welding groove models of the intersecting pipe are calculated and analyzed in welding robot workstation.In order to ensure the feasibility of multi-layers and multi-tracks welding process for welding groove of the intersecting pipe,the intersecting groove needs to cut by CNC cutting machine.The mathematical models of small pipe end groove are built.The mathematical models include groove angles of space curves intersected by inside diameter of small pipe end and big pipe and saddle-shaped space curves series.Discrete points are generated according to the results of above calculations.Groove models are fitted by three-dimensional software solidworks.These three-dimensional models are used as cutting source file of small pipe end.The experiment has accomplished the intended purpose.It provides a guarantee for welding of the welding robot workstation.
