A machine tool (2) comprising a mobile table (11) and a support and gripping device (200) for mechanical part fitted to a machine tool (2) which comprises:
- pincer means (210) for blocking said mechanical part;
- a support (250) which contains and supports said pincer means (210) and is blocked to the mobile table (11). The pincer means (210) comprise a part blocking pincer (212) and an intermediate pincer (211), respectively one inside the other, both with elastic characteristics. The blocking pincer (212) has a structure suitable for gripping the mechanical part following interaction between the intermediate pincer (211) and the support (250); furthermore the pincer means (210) are suitable to be placed in rotation around said pincer axis (P-P). The support (250) comprises means of braking and/or blocking the rotation of the pincer means (210), comprising one annular membrane (400) which act on said pincer means (210). |
