Abstract

Mandrino per utensili comprendente un corpo cilindrico presentante un foro (2) passante assiale, una boccola (6) alloggiata nel foro (2) nelle vicinanze di una (4) delle due estremità del corpo, un pistone (10) mobile alloggiato in una sede (12) nel corpo e coassiale con il foro (2), il pistone essendo appoggiato sopra la boccola (6), una camera (14) definita tra il pistone (10) e la sede (12), la camera essendo riempita con fluido, mezzi (16) di comando per regolare la pressione del fluido per cui aumentando la pressione con i mezzi (16) si sposta il pistone (10) e si comprime e si restringe circonferenzialmente la boccola (6) per bloccare un utensile nella boccola.Tool mandrel comprising a cylindrical body having an axial through hole (2), a bush (6) housed in the hole (2) near one (4) of the two ends of the body, a mobile piston (10) housed in a seat (12) in the body and coaxial with the hole (2), the piston being supported above the bush (6), a chamber (14) defined between the piston (10) and the seat (12), the chamber being filled with fluid , control means (16) for regulating the pressure of the fluid whereby increasing the pressure with the means (16) moves the piston (10) and circumferentially compresses and shrinks the bushing (6) to lock a tool in the bushing.
