Abstract

Cette invention concerne un mandrin à serrage mécanique assisté. Ce mandrin comprend des mors déplacés radialement sous l'action de cales mobiles orientées tangentiellement par rapport à l'axe de rotation du mandrin. Un organe d'entraînement rotatif centré est relié à un organe de réglage. Celui-ci peut être déplacé axialement par des moyens connus et la transformation du mouvement axial de cet organe de réglage en mouvement rotatif de l'organe d'entraînement des cales est assurée par des surfaces obliques à profil hélicoïdal de l'organe de réglage, qui coopèrent avec des surfaces antagonistes de l'organe d'entraînement L'organe de réglage est immobilisé en rotation. Un mandrin de ce type est utilisable sur toutes les machines-outils rotatives.
