Abstract

L'invention concerne une machine d'oxydocoupage déplaçable équipée d'un élément de réglage en hauteur sur un chariot transversal (4) qui se déplace transversalement sur un bâti de machine (1). Dans cette machine, une tête d'outil de profilage, notamment une tête de coupe de profilage, est reliée à l'élément de réglage en hauteur par liaison rotative et pivotante par l'intermédiaire d'un axe de rotation vertical et d'un axe de pivotement horizontal. Pour pouvoir usiner une pièce avec une grande précision même dans des zones de travail d'accès étroit et difficile, l'élément de réglage en hauteur est conçu sous la forme d'une unité poussoir (5) constituée d'un profilé fermé et en forme de caisse. Cet élément de réglage est pourvu d'un axe central (6) vertical et la tête d'outil de profilage (11) est placée en bas du profilé sur le même axe de telle manière que l'axe de rotation (12) vertical virtuel de la tête d'outil de profilage (11) se trouve dans le prolongement de l'axe central (6) vertical du profilé.
