Abstract

Selon l'invention, un outil comporte une tige d'outil (14), éventuellement creuse, tandis que la broche de machine comporte une douille de raccordement (20) présentant une cavité (18) destinée à loger la tige d'outil. Dans la zone comprise entre la tige d'outil (14) et la douille de raccordement (20) se trouve un mécanisme de serrage (22) qui comprend au moins un élément de serrage (24'') pouvant se déplacer sensiblement radialement, dont le déplacement radial peut être transformé, comme c'est le cas dans un engrenage conique, en un mouvement de serrage axial entre la tige d'outil (14) et la douille de raccordement (20). Le mécanisme de serrage comprend, selon l'invention, un écrou d'actionnement (26) qui est vissé sur un filetage extérieur (28) de la douille de raccordement (20) coaxiale par rapport à l'axe de broche, et dont le déplacement axial lors du processus de serrage, avec intercalation d'au moins un élément intermédiaire (30''), est transformé en déplacement radial de l'élément de serrage (24'').
