摘　　要：设计了一种基于CCD传感的轮式移动焊接平台机构,采用光杠配合丝杠改进常规的十字滑块机构,改善移动焊接平台整体的平衡性,降低了焊缝跟踪中对平衡控制的难度。本设计采用两个无刷直流电机驱动十字滑块实现左右和上下运动,采用一个步进电机调整CCD传感器滤光装置的位置。MIG和TIG焊枪的支撑机构选用工业型材组合装配方式,根据不同的实验环境能够调整MIG和TIG焊枪的夹角大小。该移动焊接平台结构紧凑、灵活,易于实现自身的平衡调节,可完成各种焊接实验及空间焊缝的焊接,实验得到机构的执行精度在1mm的范围内。A design of wheeled welding mobile platform was presented based on CCD sensor. Using the slick pole with the ball screw can improve the conventional cross-slider mechanism, which can also improve the welding mobile platform balance, reduce the difficulty of welding seam track for balance control. Two brushless DC motors （BLDCM） were applied in the design to drive cross-slide movement, and a stepper motor is employed to adjust the position of CCD sensor filter device. The combination structure with industrial profile is served in the support device of MIG and TIG guns to adjust the angle of the MIG and TIG welding torch in accordance with the experiment conditions. The welding mobile platform is compact, flexible, easy to implement its own balance adjustment, and it also can complete different welding experiment, including space welding seam, with the range of 1 mm of operative accuracy of the mechanism under verification.
