<p>It is described a tool spindle (1) for automatic machines comprising a body (2) provided with a longitudinal axis of rotation (A-A), a plurality of jaws (3) (or clamps) constrained to the body and movable between a position of maximum closure, proximal to the longitudinal axis of rotation, and a position of maximum opening, distal from the longitudinal axis of rotation, and means for driving the displacement of the jaws between the position of maximum closure and the position of maximum opening, and/or vice versa. The travel extend of the driving means can be adjusted to modify the position of maximum opening of the jaws. The adjustment can be preferably obtained by means of a wrench when the spindle is assembled on the corresponding automatic machine.</p> |
