Abstract

Il existe un besoin de mécanisation du travail et d'amélioration du rendement de production, l'invention concerne donc une automatisation de la fixation et du retrait d'une plaquette d'outil de coupe. Au lieu d'utiliser un mécanisme de fixation manuel par vissage de plaquette, la présente invention concerne un outil de coupe équipé : d'un dispositif de fixation de plaquette en forme de L (4), la goupille servant de point de support de rotation étant introduite dans une section d'appui formée dans le corps principal de l'outil de coupe ; d'un ressort (8), qui est fixé à l'intérieur du bout de l'outil de coupe et dont la force de restauration est appliquée au niveau du pied (16) du dispositif de fixation de plaquette pour que le dispositif de fixation de plaquette provoque une action de fixation d'une plaquette (3) ; et d'un piston hydraulique (9), qui est entraîné par un cylindre hydraulique (10) et qui est prévu pour déformer le ressort dans le sens contraire à celui de la force de restauration du ressort au niveau du pied du dispositif de fixation de plaquette et pour appliquer une force de façon à tourner le dispositif de fixation de plaquette pour qu'il libère la fixation de la plaquette.
