摘　　要：螺旋纹是阿塞尔机组热轧管关键技术指标,决定液压缸的使用性能。为提高液压缸缸筒螺旋纹检测水平,克服现有方法的局限性,提出一种基于无线信号传输的螺旋纹检测方法。根据阿塞尔机组螺旋纹周期性特点,给出检测原理与检测系统总体方案,建立螺旋纹检测数学模型。以某工程机械核心零部件为例,采用所设计检测装置与三坐标进行检测与比较,证明所设计检测装置检测误差优于0.01 mm。检测系统分析结果表明,所设计检测装置的合计量具R&R占研究变异的百分比小于30%,说明其重复性与再现性良好,进一步证明其可以应用于实际生产现场。本研究为工程机械螺旋纹等关键几何误差检测提供了技术支持。That thread is a key tech indicator of ASSEL mills for pipes heat rolling further determines application of the pipe for hydraulic cylinder use. Therefore, it has to provide a method for testing the thread with wireless signals transmission, while according to the ASSEL mills cyclist features of thread it has to provide a general solution to the test system by building up a mathematical model to test the thread. Comparison and tests show that the device so designed for the purpose has got a cutting precision at the finish with a tolerance better than 0.01 mm;a total measuring tool R&R accounts for variation is less that 30% that tells good capability in reproduction and representation, thus providing a tech support for such helicoid machining and measuring work to come in the field of construction machinery and equipment.
