A Technique of Calibrating an Optoelectronic Sensor for Monitoring of the Diameter of Tension Springs

Resumo

Features in the process of monitoring the diameter of tension springs and other spiral-like bodies in the course of their manufacture are considered and the selection of an optoelectronic method of measuring the diameter of a spring is evaluated. Structural data and the characteristics of a newly designed sensor that satisfies the technological requirements are presented. A technique for calibrating the sensor is proposed and implemented. Testing of the sensor in an actual production process is performed. Satisfactory results from a comparison of the estimators of the diameter performed by the optoelectronic technique and by indirect techniques are obtained.
