<p>A machine tool (10), particularly of the type of wood panel sizing machines, comprising
- a worktable (11),
- a tool (12) provided on one side of the worktable (11),
- a part guiding arm (13), which can slide in a working direction (A) along the worktable (11) to move a part (14) retained thereon so that it interferes in a guided manner with the tool (12) to be machined by it,
- a driving slider (15), which supports a first abutment (16) for positioning a part (14) in abutment against the arm (13) and is supported by the arm (13) so that it can slide along an axis (B) that is longitudinal thereto and is connected to means (17) for actuating its driven sliding movement along the longitudinal axis (B),
- at least one driven slider (18), which supports a second abutment (19) for positioning the part (14) in abutment against the arm (13) and is supported by the arm (13) so that it can slide along the longitudinal axis (B),
- an element (20) for the extension of the arm (13), which is supported thereby so that it can slide along the longitudinal axis (B) to protrude from its free end in a manner that can be modulated and supports a third abutment (21) for positioning a part (14) in abutment against the arm (13),
- means (22) for the temporary and reversible coupling of the driving slider (15) with the driven slider (18) and/or with the extension element (20), for the entrainment of the driven slider (18) and/or of the extension element (20) by the driving slider (15) along the longitudinal axis (B),
- means (28) for the temporary and reversible locking of the sliders (15, 18) and/or of the extension element (20) to the arm (13).</p> |
