Abstract

In una morsa autocentrante M per l'ammorsaggio di pezzi in lavorazione nelle macchine utensili, del tipo comprendente una coppia di ganasce 1 contrapposte portanti organi intercambiabili di bloccaggio dei pezzi, in cui il reciproco avvicinamento delle ganasce per il serraggio di detti organi sui pezzi viene ottenuto attraverso il movimento - trasversalmente alla direzione di spostamento delle ganasce - di un cuneo 6 con il quale le ganasce cooperano mediante guide inclinate in reciproco impegno di scorrimento, l'angolo al vertice ? di detto cuneo viene scelto ampio più di 60° e preferibilmente intorno a 90°, così eliminando o limitando drasticamente i possibili momenti di ribaltamento agenti sulle ganasce 1, per assicurare una maggior precisione dell'ammorsaggio.
