摘要本文简略的说明了无缝钢管表面与近表面缺陷涡流旋转探头检测机构的设计过程，对今后设计此类产品有一定的借鉴和参考作用。

    本文清楚的说明了无缝钢管表面与近表面缺陷涡流旋转探头检测机构的设计流程，主要研究了从机架到轴承的设计选择过程，而且清楚的说明了各个零件的选用原则和方法，对其中需要计算的部分有详细的公式给出，而且每个标准都是严格参照手册进行选择，有较高的参考价值。

    整个设计的重点托起无缝钢管及使无缝钢管穿过涡流旋转检测机构的过程，本文创新的选择了一个液压缸，利用杠杆机构来同时实现待检测无缝钢管来穿过检测机构。理论上，该套设备能够满足无缝钢管从进料到出料的整个过程的各个要求，各个参数都能与无缝钢管缺陷涡流检测机构的其他装置相匹配。42070

ABSTRACT

This paper briefly describes the design process of the seamless steel tube surface and near surface defect eddy current rotating probe detection mechanism, which has a certain reference and reference for the design of such products in the future.

The clearly illustrates the design process of seamless steel tube surface and near surface defect of eddy current rotating probe inspection agencies, mainly studies from rack to bearing design selection process, and clearly illustrates the various parts of the selection principle and method of, the need to the calculation of the Ministry have given detailed formulas, and each standard are strictly refer to manual selection, have a high reference value.

The design of key hold seamless steel pipe and seamless steel pipe through the rotary vortex detection mechanism. The innovation of this paper chose a hydraulic cylinder, make use of lever mechanism to simultaneously achieve detected seamless steel tube to pass the detection mechanism. Theoretically, the equipment can meet the requirements of the whole process of seamless steel pipe from the whole process, and each parameter can be matched with other devices of seamless steel pipe flaw eddy testing mechanism.

Key words:Seamless steel tube; surface defect; eddy current; inspection mechanism
