摘要凸轮机构广泛应用于自动化机械、自动化控制系统中，是影响发动机气门开闭间隙大小和配气效率的主要因素。随着凸轮轴自动化加工水平的不断提高，为了处理、评定它的各项工艺误差高，并正确精度、高效率地检测凸轮轴，快速地反馈凸轮轴的质量信息，传统的光学机械量仪方法已经不能适应凸轮轴工艺质量管理的实际检测需要，因此采用了涡流检测系统这种无损检测方式来进行凸轮轴的表面缺陷检测，对今后设计此类产品有一定的借鉴和参考作用。47325

Camshaft surface defect detecting mechanism design eddy current testing
systemAbstract: Cam mechanism widely used in automated machinery, automatic control system, is a major factor affecting engine valve opening and closing the gap size and gas distribution efficiency. With the camshaft increasing levels of process automation, order processing, assess its various high technology error, and correct precision, high efficiency detection of the camshaft, quality information feedback quickly camshaft, conventional optical mechanical meter method camshaft been unable to meet the actual testing process quality management needs, so using eddy current testing system NDT this approach to the camshaft surface defect detection for the future design of such products have some reference and reference.
This article clearly illustrates the camshaft surface eddy current flaw detection system mechanism design process, mainly studied the selection process from the overall structure of the motor, and the selection rules and methods of the various parts, the paper detailed formulas and calculations, each We are in strict accordance with the formula given in accordance with the relevant books, have a high reference value.
Theoretically, this set of equipment can meet various requirements from the camshaft detected fed the whole process, various parameters can be other devices with the camshaft surface defect detection means of eddy current testing system to match.
