摘要

摘要：针对目前焊接监控系统与焊枪分离引起的结构冗余与干涉，以及取像偏离熔池中心等问题，设计了一种带有视觉功能的同轴一体化焊枪，摄像机与钨极同轴，同时安装在焊枪的内部，可以同步监测焊缝的质量.设计了钨极调节系统，并将冷却和保护系统设计为一个整体，从而使钨极的调节、焊枪的冷却降温以及气体的保护效果更好，优化了焊枪的结构，提高了焊枪的可达性及可操作性.实验表明，本焊枪结构可获得以钨极为中心的熔池图像，可以清晰地定位钨极和焊丝位置，对比传统的视觉结构，该一体化焊枪机构在焊缝跟踪、过程监控等应用上有明显的优势.

Abstract：

Abstract： For the issues of structural redundancy, interference of the welding torch and images deviation from the center of weld pool caused by separation between the welding monitoring system and torch, a coaxial welding torch with visual function (coaxial integration with the visual function, CIV) was designed, whose camera is coaxial to the tungsten electrode, installed in the interior of the welding torch, which can provide real time monitoring of the welding processing. Innovation design of the tungsten electrode regulating system simplifies the regulation of tungsten electrode. The cooling and protection system were integrated, which has a dramatically effect on welding gun cooling and gas shielding. It not only optimizes the structure of the welding torch, but also improves the accessibility of the welding gun. The result shows that a very central pool image of tungsten and the exact positions of tungsten and welding stick can be obtained by the structure of the CIV torch. The structure of CIV torch is more advantageous in the applications of seam tracking, process monitoring.
