Abstract

Dispositif de perçage automatique à moyens de génération d’avance vibratoire débrayable automatiquement La présente invention concerne un dispositif de perçage comprenant un carter et une broche apte à porter un outil coupant, ladite broche étant montée mobile en rotation et en translation selon un même axe à l’intérieur dudit carter, ledit dispositif comprenant des moyens moteurs reliés à ladite broche au moyen d’une transmission apte à générer un mouvement combiné de rotation et de translation de ladite broche selon ledit axe, ledit dispositif comprenant une butée portée par ladite broche délimitant une course maximale prédéterminée de translation de ladite broche dans le sens d’un perçage, ladite course maximale étant atteinte lorsque ladite butée se trouve dans une position de fin de perçage, ledit dispositif comprenant des moyens de génération d’une avance axiale vibratoire induisant une oscillation périodique de ladite translation de ladite broche selon deux directions opposées de sorte à générer un mouvement d’avance vibratoire de ladite broche le long dudit axe. Selon l’invention, ledit dispositif comprend des moyens de débrayage automatique desdits moyens de génération d’une avance axiale vibratoire, après que ladite butée se trouve dans ladite position de fin de perçage, ledit débrayage automatique permettant une rotation de ladite broche selon ledit axe sur au moins un angle prédéterminé sans aucune avance. Fig. 4The present invention relates to a drilling device comprising a housing and a spindle capable of carrying a cutting tool, said spindle being mounted to be movable in rotation and in translation along the same axis at inside said housing, said device comprising motor means connected to said spindle by means of a transmission capable of generating a combined movement of rotation and translation of said spindle along said axis, said device comprising a stop carried by said spindle delimiting a predetermined maximum travel of translation of said spindle in the direction of drilling, said maximum travel being reached when said stop is in an end-of-drilling position, said device comprising means for generating a vibratory axial advance inducing a periodic oscillation of said translation of said spindle in two opposite directions d e so as to generate a vibratory advance movement of said spindle along said axis. According to the invention, said device comprises means for automatically disengaging said means for generating a vibratory axial advance, after said stop is in said drilling end position, said automatic disengaging allowing rotation of said spindle along said axis. on at least a predetermined angle without any advance.
