Abstract

L'invention concerne un appareil d'usinage équipé d'un mécanisme d'échange de pièces à usiner sous une forme qui n'augmente pas des limitations structurales sur le mécanisme d'échange de pièces à usiner ni ne réduit l'efficacité d'usinage des pièces à usiner, même pour un appareil d'usinage dans lequel un magasin d'outils et une table de travail se déplacent d'un seul tenant. L'appareil d'usinage (100) est pourvu d'une tête d'usinage (101), d'un mécanisme (110) de mouvement dans la direction axiale Y et d'un mécanisme (116) d'échange de pièce. La tête d'usinage (101) est pourvue d'un arbre principal (102) destiné à maintenir détachable un outil d'usinage (104) et à effectuer des va-et-vient dans les directions axiales X et Y. Le mécanisme (110) de mouvement dans la direction axiale Y est pourvu de tables de travail (108) destinées à supporter des pièces à usiner (WK), d'un magasin (112) d'outils et d'une séparation (117) de région d'usinage, et leur fait effectuer des va-et-vient d'un seul tenant dans la direction axiale Y. Le mécanisme (116) d'échange de pièce à usiner est placé au niveau d'une position dans laquelle le mécanisme peut échanger des pièces à usiner (WK) au niveau de la position des tables de travail (108) sur la direction axiale Y lorsque le magasin (112) d'outils est situé au niveau de la position d'échange d'outil d'usinage (104), et échange les tables de travail (108) sur le mécanisme (110) de mouvement dans la direction axiale Y.
