Definitions

  • the tool holder serves to fix a fixed tool 11, e.g. a lathe tool for external machining of a rotating workpiece or a plunge-cut tool for internal machining of such a workpiece on a tool holder 12, which is only schematically indicated, on an NC- or CNC-controlled machine tool represented by the latter, in which the tool holder on a - not shown - Support is arranged, which is arranged to be movable parallel to and at right angles to the axis of rotation of the rotatingly driven workpiece on the machine frame, the central longitudinal axis 13 'of the tool carrier 12 and the central longitudinal axis of the tool carrier 12 being aligned therewith when the workpiece is rotated Tool holder 10 generally run at a lateral distance from and parallel to the axis of rotation of the workpiece.

Abstract

L'invention concerne un porte-outils (10) recevant des outils fixes (11) au moyen desquels sont usinées des pièces tournant sur une machine-outil à commande numérique ou à commande numérique par calculateur. Ce porte-outils (10) comporte un support de base (14) et un support interchangeable (16) ainsi qu'un dispositif de serrage qui assujettit le support interchangeable sur le support de base et qui comprend des tirants de raccordement (44, 46) pouvant agir sur le support de base et le support interchangeable et pouvant être axialement serrés. Ces tirants de raccordement (44, 46) présentent chacun un élément de traction (47, 48), lequel est ancré, par liaison de forme et de manière à résister à la traction axiale, sur l'un des deux supports, et un élément de serrage (49 ou 51) qui est monté sur l'autre des deux supports (14 ou 16) de manière à tourner autour d'un axe de rotation (92, 93) perpendiculaire à l'axe longitudinal des supports et espacé de celui-ci. Les éléments de serrage (49, 51) se présentent sous la forme de leviers à deux bras qui peuvent être mis en rotation par actionnement de vis de serrage (81, 82), ce qui permet d'assujettir les supports (14, 16) l'un à l'autre par liaison de force et de forme.
