Abstract

La présente invention concerne une rectifieuse plane à deux têtes de type vertical pour usiner un disque de frein, la rectifieuse plane étant capable de rectifier les deux surfaces de diverses pièces en forme de disque sans changer les porte-pièces. La rectifieuse plane comporte une paire de meules supérieure et inférieure (2, 3) qui tournent autour d'un axe vertical et les porte-pièces rotatifs (9) pour retenir, en tant que pièce (W), le disque de frein qui possède un trou central (18). La pièce (W) retenue dans les porte-pièces (9) est insérée entre les deux meules (2, 3) tout en tournant autour du centre de la pièce, et ainsi les deux surfaces, supérieure et inférieure, de la pièce (W) sont rectifiées en même temps. Chacun des porte-pièces (9) possède trois coulisseaux (40), ou plus, disposés sur le corps de porte-pièce rotatif (10) à des intervalles égaux dans la direction circonférentielle et mobiles dans la direction radiale. Les coulisseaux (40) sont installés sur des griffes de mandrin (41) capables de prendre appui contre le bord périphérique du trou central (18) de la pièce (W) à partir du côté d'axe rotatif du corps de porte-pièce (10), et les coulisseaux (41) sont simultanément mobiles de façon radiale selon une quantité égale conjointement au fonctionnement d'un dispositif d'entraînement unique.
