Title (EN) A SYSTEM FOR MOVING A TOOL IN A MACHINE TOOL
(FR) SYSTÈME DESTINÉ À DÉPLACER UN OUTIL DANS UNE MACHINE-OUTIL
Abstract:
(EN) Described is a system for moving a tool in a machine tool, comprising a frame (102), a member (103) movable relative to the frame along or about an axis of movement (M), a unit (104) for transmission of the rotating motion operatively interposed between the frame (102) and the movable member (103), a hydraulic stop unit (105) operatively interposed between the frame (102) and the movable member (103) and a control unit (12) associated with the transmission unit (104) and with the stop unit (105) for controlling them. The stop unit (105) comprises at least a first element (106) rigidly connected to the frame (102), at least a second element (107) rigidly connected to the movable member (106) and a hydraulic actuation circuit (13) configured for moving the first (106) and the second element (107) towards and/or away from each other according to a command issued by the control unit (12), wherein the control unit (12) is configured for selectively controlling the hydraulic actuation circuit (13) at a first pressure (P1), in which it generates a first contact force between the first (106) and the second element (107), or at a second pressure (P2), in which it generates a second contact force between first (106) and second element (107), greater than the first pressure (P1).
(FR) L'invention concerne un système pour déplacer un outil dans une machine-outil, comprenant un cadre (102), un organe (103) mobile par rapport au cadre le long ou autour d'un axe de mouvement (M), une unité (104) pour la transmission du déplacement rotatif interposé fonctionnellement entre le cadre (102) et l'organe mobile (103), une unité d'arrêt hydraulique (105) intercalée fonctionnellement entre le cadre (102) et l'organe mobile (103) et une unité de commande (12) associée à l'unité de transmission (104) et à l'unité d'arrêt (105) pour commander ces dernières. L'unité d'arrêt (105) comprend au moins un premier élément (106) solidarisé au cadre (102), au moins un second élément (107) solidarisé à l'organe mobile (103) et un circuit d'actionnement hydraulique (13) conçu pour déplacer le premier élément (106) et le second élément (107) l'un vers l'autre et/ou l'un à distance de l'autre selon une commande émise par l'unité de commande (12), l'unité de commande (12) étant conçue pour commander sélectivement le circuit d'actionnement hydraulique (13) à une première pression (P1), dans laquelle il génère une première force de contact entre le premier élément (106) et le second élément (107), ou à une seconde pression (P2), dans laquelle il génère une seconde force de contact entre le premier élément (106) et le second élément (107), supérieure à la première pression (P1).
