Abstract

L'invention concerne les machines-outils. Elle a pour objet un dispositif de serrage comportant une pièce fixe 1, 3 et une pièce mobile 2, 4 actionnée par un vérin hydraulique 5, 6, 7, une broche de déplacement rapide 10 et une broche d'entraînement 18. Cette dernière porte une butée 24 qui vient rencontrer une douille de butée 27 réglable axialement sur la broche 10, de manière à limiter le déplacement de la broche 18 correspondant à une augmentation de la force de serrage. Application au réglage et à la limitation de la force de serrage d'un étau de machine
