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.
Keywords: Camshaft; surface defects; detecting means;
