针对多数弧焊机器人商品化离线编程系统技术不公开、价格昂贵,且缺乏复杂焊接件及设备建模能力的现状,提出基于三维设计软件开发经济适用型离线编程系统的思路. 运用SolidWorks三维建模功能、二次开发接口平台和VC++6 . 0 ,构建OTC弧焊机器人离线编程系统. 该系统具有实体建模、离线示教和碰撞检测等功能,并且能编写直接导入机器人控制柜中的程序. 通过对比离线编程系统的规划轨迹和实际机器人再生程序时焊枪末端运动轨迹的结果表明,系统较好地实现了弧焊机器人的离线编程.%For the majority of commercial arc welding robot off-line programming systems are private, ex-pensive, and lack of complex welding and equipment modeling capabilities, the approach of developing an economic and reingistic off-line programming system which is based on 3D design software is proposed. In order to achieve this idea, the OTC robot off-line programming system is built by using the SolidWorks 3D modeling capabilities and its secondary development interface platform and VC + + 6. 0 software. This system has realized the functions of 3D modeling, off-line teaching, collision detection and it can write pro-grams which can be directly imported to the robot' s control cabinet. By comparing the real robot reproduce trajectory and the planning trajectory of system, the result shows that this system is feasible.
