Abstract: This paper presents a detection system for wheel billet end face angular deviation based on laser ranging method. Using three parallel lasers Irradiate the checking surface at the same time, the distance between the wheel billet end face and the laser sensors can be obtained, then the angle between the checking face and the reference plane is calculated by using the geometric theory and the standard cylindrical steel billet. And the multi-sensor networks based on the CANopen protocol and the communication conversion module is constructed to achieve the data transmission and display. The wheel is marked and excluded when it exceeds the allowable tolerance before the following process, the saw machine and the saw blade is repaired when the system alarms. The effective of detection system and measurement algorithm is verified through field test.


Keywords: Laser ranging, Wheel billet, Billet face, Angular deviation, Detection system.
