Abstract

Il dispositivo trascinatore frontale per macchine utensili comprende un corpo allungato e dotato, secondo il proprio asse longitudinale, di un codolo tubolare e di una cavità che è chiusa frontalmente da un coperchio presentante, secondo detto asse longitudinale, una punta di centraggio. Una pluralità di artigli sono disposti sul coperchio attorno alla punta di centraggio e guidati scorrevoli parallelamente ad essa. Una bussola, montata scorrevole longitudinalmente all'interno di detta cavità, è solidale allo stelo di un organo spintore guidato assialmente lungo detto codolo, per la trasmissione di una spinta assiale prodotta da un organo di azionamento pneumatico. La bussola porta un organo di bilanciamento dotato di una coppia di linguette, oscillanti indipendentemente secondo un asse trasversale a detto asse longitudinale, sulle quali sono destinate ad appoggiare le estremità interne degli artigli.The front driving device for machine tools comprises an elongated body and equipped, according to its longitudinal axis, with a tubular tang and a cavity which is closed at the front by a cover having, according to said longitudinal axis, a centering point. A plurality of claws are arranged on the cover around the centering tip and guided sliding parallel to it. A bush, mounted sliding longitudinally inside said cavity, is integral with the stem of a pusher member driven axially along said tang, for the transmission of an axial thrust produced by a pneumatic actuation member. The bush carries a balancing member equipped with a pair of tabs, independently oscillating along an axis transverse to said longitudinal axis, on which they are intended to rest the internal ends of the claws.
