Research on Electromagnetic Ultrasonic Automatic Measurement System for Wall Thickness of Cabin Parts

特种装备舱段件壁厚尺寸要求严格,导致其在加工过程中,需要进行多次的人工测量。上述过程存在耗时长、效率低、精度不高等问题,严重影响了生产节拍提升和成本控制。为此,开展了舱段件壁厚电磁超声自动测量方法研究,提出了壁厚测量系统的总体框架,进行了测量机械本体设计、测头运动路径规划、壁厚数据采集整理等,构建了在线测量系统,并开展了测量验证试验。实验结果表明,基于该方法构建的壁厚自动测量系统,可直接求解出舱段件各点壁厚;与相比传统方式,具有自动化程度高、测量效率高、误差小等特点。

The wall thickness of some equipment compartments is strictly required,resulting in multiple manual measurements during the machining process.The above process has problems such as long time-consuming,low efficiency,and low precision,which seriously affects production tact improvement and cost control.To this end,the research on electromagnetic ultrasonic automatic measurement system for wall thickness of cabin parts was carried out,and the overall framework of the wall thickness measurement system was proposed.The measurement of the mechanical body design,the probe motion path planning,the wall thickness data collection and so on,and the like were constructed.The online measurement system was carried out and a measurement verification test was carried out.The experimental results show that the wall thickness automatic measurement system based on this method can directly solve the wall thickness of each point of the cabin section;compared with the traditional method,it has high automation degree,high measurement efficiency and small measurement error.
