Abstract

La présente invention concerne un dispositif pour réaliser un couplage amovible de deux pièces (10, 12), par exemple de deux pièces d'outil. La première pièce (10) présente un axe d'ajustage cylindrique (14) et une surface plane (22) qui délimite l'axe d'ajustage à sa base (28) et qui fait saillie radialement, alors que la seconde pièce (12) présente un manchon de réception (16) à surface intérieure cylindrique (32). L'invention fait également intervenir un mécanisme de serrage (20) qui, au cours du processus de serrage, assure l'insertion de l'axe d'ajustage (14) dans le manchon de réception (16), et l'appui mutuel entre la surface plane (22) et la surface frontale (24). Pour garantir avec des moyens simples, un centrage exact des pièces, le manchon de réception présente selon l'invention une partie conique intérieure (34) qui diverge de la surface intérieure cylindrique vers la surface frontale, et l'axe d'ajustage porte un anneau de centrage (29) à déformation élastique, disposé au niveau de la base et présentant une partie conique extérieure complémentaire de la partie conique intérieure (34).
