<p>An automatic working centre for frame pieces comprises a work table (3) formed by a group of mobile cross bars (4), wherein each bar (4) is equipped with locking means (5) for the pieces (2) to be worked. The locking means (5) include at least two pressers (6) which are driven with a roto-translation movement so as to pass from a standstill position, in which they do not interact with the pieces (2), to a working position, in which they clamp the pieces (2) during machining, and vice versa. The pressers (6) include sections of surfaces (61), shaped so as to complement one another, allowing the pressers (6) also act on the pieces (2) to be worked at the same time.</p> |
