Title (EN) A CHUCK FOR A HIGH PRECISION MACHINE TOOL
(FR) MANDRIN POUR UNE MACHINE-OUTIL DE HAUTE PRÉCISION
Abstract:
(EN) A chuck for a machine tool having a rotation spindle (14) with a main axis of rotation (19). The chuck comprises a base plate (1), a first rotatable plate (2) eccentrically mounted on the base plate (1), a second rotatable plate (3) eccentrically mounted on the first rotatable plate (2), balancing means (6, 11) for aligning a principal axis of inertia of the chuck with the main axis of rotation (19) and a holding mechanism (17,18). The chuck is provided with an actuating mechanism for angularly displacing the first rotatable plate (2) around a first rotation axis (20) over a first angle of rotation and/or the second rotatable plate (3) around a second rotation axis (21) over a second angle of rotation such that the position of the object (13) with respect to the main axis of rotation (19) can be altered.
(FR) La présente invention concerne un mandrin pour une machine-outil comportant une broche de rotation (14) avec un axe principal de rotation (19). Le mandrin comprend une plaque de base (1), une première plaque rotative (2) montée excentriquement sur la plaque de base (1), une seconde plaque rotative (3) montée excentriquement sur la première plaque rotative (2), des moyens d'équilibrage (6, 11) pour aligner un axe d'inertie principal du mandrin avec l'axe de rotation principal (19) et un mécanisme de maintien (17, 18). Le mandrin est muni d'un mécanisme d'actionnement pour déplacer angulairement la première plaque rotative (2) autour d'un premier axe de rotation (20) sur un premier angle de rotation et/ou la seconde plaque rotative (3) autour d'un second axe de rotation (21) sur un second angle de rotation, de telle sorte que la position de l'objet (13) par rapport à l'axe principal de rotation (19) peut être modifiée.
