Abstract

Un ensemble de boîtier ajustable est présenté, qui comprend un logement cannelé et une bague de réglage qui comporte un mandrin cannelé. Le mandrin cannelé peut être déplacé axialement dans lensemble de boîtier lorsque dégagé des portions, en amont et en aval, dun train de tiges afin de dégager le mandrin du logement cannelé. Le mandrin cannelé peut être pivoté au moyen de la bague de réglage en vue de modifier les interfaces inclinées entre les composantes et de changer langle dinclinaison dans le logement.
