Abstract: In order to realize multipoint measurement for the thickness of bearings, a method for the multipoint measurement of bearings thickness was presented based on optical triangulation measurement principle. The measurement principle, the composition and the mathematical model were presented. The system was composed of three parts, including automatic sending the material machine, measurement machine and grouping machine. With the method of pressing the bearing into the model, the error introduced by the extension of the bearings was eliminated. The real-time data record processing system was designed based on LabVIEW, and the thickness of bearings was collected fleetly and exactly. The system can satisfy the requirement for the on-line grouping of the thickness of bearings.
