Abstract

La présente invention concerne une machine de perçage de profil assurant une commutation pratique entre des tiges à forets. La machine comprend un établi (1), et un évidement de maintien d'objet (11) est disposé sur l'établi (1). Un ensemble de perçage est disposé au-dessus de l'évidement de maintien d'objet (11), et comprend une base (2) entraînée au moyen d'un ensemble d'entraînement à vis. La base (2) est pourvue d'une cavité (21). Une plaque tournante (51) est disposée rotative dans la cavité (21), et un mécanisme de positionnement est disposé sur la base (2) et utilisé pour limiter la rotation de la plaque tournante (51). Une partie de la plaque tournante (51) s'étend hors de la cavité (21). Une pluralité de tiges à forets (52) ayant des diamètres de tige différents sont disposées à demeure sur une surface circonférentielle de la plaque tournante (51) de manière circonférentielle et équidistante. L'ensemble de perçage composé de la base (2) et de la plaque tournante (51) est conçu pour fonctionner en coordination avec le mécanisme de positionnement, de telle sorte que les tiges à forets (52) peuvent être commutées au moyen de la rotation de la plaque tournante (51) sans avoir à effectuer de manière répétée des opérations de détachement et de fixation, ce qui améliore ainsi l'efficacité de commutation.
