Vision System Non Contact Measurement of Pintail Type Fasteners 2010-01-1870

Accurately measuring the length of a pintail type fastener is limited by the process of forming the fastener. When the pintail is formed its overall length is not dimensionally controlled. To accurately measure the grip of the bolt a vision system is utilized that finds the notch between the tail and bolt shank. The grip, diameter, and angle of the bolt prior to insertion are then measured. This method proves to be more accurate than measuring the bolt mechanically and provides a number of other advantages including; decreased measurement time, improved accuracy, FOD detection, and angle of the bolt in the fingers prior to insertion.
