Abstract

L'invention concerne une machine-outil comportant un porte-pièces (6) et un ou plusieurs porte-outils (4) qui sont agencés dans des compartiments d'application de la machine-outil. La machine-outil sert à l'usinage de pièces (16), en particulier de bielles qui sont usinées dans un espace de travail (20) de la machine-outil. Le porte-pièces est chargé et déchargé par un dispositif (8) d'amenée de pièces. Le dispositif d'amenée de pièces est à cette fin muni d'un corps de support (14) sur lequel des pièces usinées et non usinées peuvent être agencées et sont interchangées par le porte-pièces lors de l'opération de chargement et déchargement. L'invention vise à aménager de manière flexible, en particulier de manière peu encombrante, le dispositif d'amenée de pièces par rapport à la machine-outil. A cet effet, le corps de support peut être déplacé, en particulier pivoté, le long d'au moins deux axes de la machine. Il peut ainsi être introduit de manière flexible à l'intérieur de l'espace de travail par un côté extérieur de la machine-outil.
