Abstract

L'invention concerne un logement d'écartement convenant pour le centrage et le support de force d'outils dans des carters de soupape (2). Pendant différentes étapes d'un usinage du carter de soupape (2), le dispositif (41) peut demeurer dans le carter de soupape (2), en tant que support d'outil exactement reproductible. Un chariot d'ajustement X-Y (A) permet un ajustement d'un manchon de centrage (Z) et constitue ainsi un système de référence de haute précision, par rapport à un axe de symétrie du carter de soupape (2). La bonne précision de répétivité lors du positionnement des outils dans le manchon de centrage (Z) permet un changement d'outils rapide et reproductible, qui n'exige aucun autre mesurage, ni nouvelle orientation. Le support d'outil à précision de répétivité déploie ses avantages, notamment dans un ensemble comportant un système de changement d'outils pour des tâches multifonctionnelles d'usinage et de mesures. Tous les outils nécessaires peuvent être mis en place, par l'intermédiaire d'un cône de réception, avec une précision reproductible, dans le manchon de centrage Z du dispositif (41). Le dispositif (41) permet en outre une stabilisation des outils qui sont mis en place dans le manchon de centrage (Z). Le support de force dans le carter de soupape (2) est en outre suffisant, selon l'invention, pour des processus d'usinage de surfaces trempées.
