It is therefore possible that the two machine beds are firmly screwed together for transportation and that the entire vertical lathe can thus be transported as a unit.

Abstract

L'invention concerne un tour vertical à deux broches, ou plus, qui comportent des poupées présentant un mandrin et dont les mandrins sont disposés en vis-à-vis ou dans le même sens. Un porte-outil est affecté à chaque poupée et on peut amener une première poupée de sa position de travail, sur une glissière transversale par rapport à son axe de rotation, dans une position alignée par rapport à l'autre poupée et en direction de son axe de rotation, la glissière de la poupée déplaçable allant latéralement, par-delà la position du porte-outil affecté, jusqu'à une position de réception sur un dispositif de transport de pièce. Le tour selon l'invention est caractérisé en ce que les deux poupées (4, 10) sont logées, dans leur position de travail, dans leur propre banc (1a, 1b), isolé contre les vibrations et étanche par rapport à l'autre le long d'une fente de séparation (22), et en ce que les deux bancs (1a, 1b) peuvent être reliés pour le transport des pièces (6) d'une poupée à l'autre, au moins dans la zone des glissières (2), ou pour le transport des deux bancs (1a, 1b). Le tour selon l'invention est également caractérisé en ce que la deuxième poupée (10) peut être amenée, sur une glissière (12) dans l'axe des X, d'une position de réception de pièce (A) dans une position de remise de pièce (C) en passant par une position d'usinage (B) sous le porte-outil (11).
