Abstract

L'invention concerne les machines-outils. L'appareil ou mandrin faisant l'objet de l'invention est caractérisé instamment en ce que ses mors 5 successifs sont liés entre eux par des chaînes cinématiques 17, 19, 22, 23 de façon à constituer au moins trois paires de mors disposés symétriquement et en ce qu'il comporte un seul dispositif de manoeuvre, commun à toutes les paires de mors et assurant leur déplacement en synchronisme. L'invention peut être utilisée notamment sur les tours et les aléseuses multibroches et monobroches.The invention relates to machine tools. The apparatus or mandrel forming the subject of the invention is characterized urgently in that its successive jaws 5 are linked together by kinematic chains 17, 19, 22, 23 so as to constitute at least three pairs of jaws arranged symmetrically. and in that it comprises a single operating device, common to all the pairs of jaws and ensuring their movement in synchronism. The invention can be used in particular on lathes and multi-spindle and single-spindle boring machines.
