Abstract

La présente invention a trait à un porte-outil et à un procédé de fixation d'outil utilisant un alliage à mémoire de forme. Le porte-outil permettant de fixer un outil comprend : une unité de montage d'outil ayant un trou de fixation d'outil pénétrant à travers celle-ci, lequel trou de fixation d'outil est pourvu d'un diamètre intérieur qui est relativement plus petit que le diamètre extérieur d'une unité de manche de l'outil ; et au moins un anneau en alliage à mémoire de forme inséré dans un trou de fixation d'anneau formé à travers l'unité de montage d'outil de sorte que le trou de fixation d'anneau est doté d'un diamètre intérieur qui est relativement plus grand que le trou de fixation d'outil. La dimension du diamètre intérieur du trou de fixation d'outil varie de façon forcée au moyen de la transformation de l'anneau en alliage à mémoire de forme causée par une source de chauffage et une source de refroidissement prévues dans l'anneau en alliage à mémoire de forme, de sorte à serrer ou à desserrer l'outil.
