摘　　要：针对挤压棒材检测效率低的问题,分析了挤压棒材的检测难点,提出了一种挤压棒材的机器人超声无损检测系统。该系统从功能上可以分为被检件的运动控制与超声检测两部分。经试验验证,该系统能准确识别挤压棒材中的缺陷,不仅检测速度快,而且工作效率高,具有较大的应用前景。Aiming at the problem of low detection efficiency of extruded bars, this paper analyzes the difficulties of extruded bar inspection and a robotic ultrasonic nondestructive testing system for extruded bars is therefore proposed. The system can be functionally divided into two parts: motion control of the test piece and ultrasonic testing. After experimental verification, the system can accurately identify the defects in the extruded bars with high efficiency and fast detection speed, which has a greater application prospect.
