<p>A spindle for tools for machining wood panels or the like in related work centres comprises a containment body for a motorised shaft (2) able to be connected to a tool (3) housed, able to rotate, within a related hold (4); the hold (4) is able to be coupled in a related seat (1s) obtained at one end (la) of the body, and to be locked therein, with no ability to rotate, through related gripping and releasing means (5) positioned and defined the end (1a) of the containment body and the housing seat (1s) for the hold (4); said means (5) comprise a first cylindrical element (6) encompassing a portion of the hold (4); a plurality of spherical body (7) for securing the hold (4), uniformly distributed along its circumference, and able to be interposed between the hold (4) and a second abutting cylindrical element (9), and means (10) for supporting the two cylindrical elements (6, 9) and for axially actuating, in the two directions, the first cylindrical element (6) between a rear operative position gripping the hold (4), and an advanced operative position releasing the hold (4) in correspondence with a simultaneous radial actuation of the plurality of spherical bodies (7) away from the portion of hold (4) through an inclined profile (11) obtained on the inner surface of the second cylindrical element (9). <IMAGE></p> |
