Abstract

Pinza per torni automatici comprendenti ganasce esternamente coniche, tre bicchieri coassiali composti da un collare e da linguette longitudinali elastiche agenti sulle ganasce ed un anello di reazione a doppia conicità interna che circonda la sommità delle ganasce ed il bordo del primo bicchiere esterno a doppia conicità interna ed esterna che circonda a sua volta la parte inferiore delle ganasce ottenendosi con ciò un movimento traslante delle ganasce sia nella chiusura della pinza per l'azione del bordo del primo bicchiere sull'anello e sulla parte posteriore esterna delle ganasce e per l'azione dell'anello sulla parte anteriore esterna delle ganasce e sia nell'apertura della pinza per la reazione elastica delle linguette del secondo e terzo bicchiere su parti interne rispettivamente anteriore e posteriore delle ganasce.
