Patent

CA 2009602

A holder for use with a plurality of optical fibers that illuminate a workpiece has a central bore through which the fibers extend. Screws and springs are used to adjust the orientation of the fibers with respect to each other in order to achieve different illumination patterns on the workpiece. Instead of the screws, motor driven micrometer shafts and wedges can be used. A method of processing a workpiece comprises adjusting the orientation of a plurality of optical fibers to obtain a selected illumination pattern on the workpiece, and illuminating the workpiece with high power laser beams eminating from the fibers.

Support pour faisceau de fibres optiques destinées à éclairer une pièce à travailler. Le support comporte un trou central par lequel passent les fibres optiques. Des vis et des ressorts règlent l'orientation des fibres l'une par rapport à l'autre afin de créer divers éclairages pour la pièce à travailler. Des arbres micrométriques actionnés par moteur et des coins peuvent remplacer les vis. Une méthode de traitement de pièces à travailler comprend le réglage de l'orientation de plusieurs fibres optiques en vue d'obtenir l'éclairage voulu pour la pièce à travailler, et pour éclairer cette dernière au moyen de faisceaux laser à puissance élevée transmis par les fibres.
