摘　　要：为了提高焊装效率,柔性化焊装自动线上将总拼工位分成预拼工位和焊装工位。文中为自动线预拼工位设计了一种机器人预拼抓具,通过对侧围MCP的布置优化了抓具结构,同时应用CATIA中DMU模块对每个单元进行运动过程模拟,检查干涉情况,对框架结构进行有限元分析,使框架刚度满足使用要求。实际运用表明此种机器人抓具能充分利用工业机器人的高精度和柔性化能力,准确地抓取工件并迅速完成拼装。In order to improve the efficiency of welding,the pre-assembly station is arranged in a flexible automatic welding line.The author designed a robot welding gripper for the pre-assembly station,and optimized the structure by arranging MCP,simulating the motion of each unit using the CATIA DMU module to inspect the interference and also making the strength of the framework meets the demand by CAE analysis.The practical application indicated this robot gripper could make good use of the high-accuracy and flexibility of robots to grab workpiece accurately and assemble quickly.
