Abstract
A machine tool has a multiplicity of stationary tool spindles that are optionally displaceable from a retracted rest position into an extended working position are positioned at various positions in a frame-like stand which defines and comprises machining space, and has a workpiece manipulator by way of which a workpiece support is movable multi-axially in translation and preferably also in rotation. In order to create advantageous loading conditions, it proposed that a loading door is associated with at least one of the leg walls defining the machining space, and that a workpiece support holder, which is equipped with a coupling for the workpiece support, is arranged on at least one, preferably on both, loading door panel fronts.
Claims12
Machine tool (1) comprising:
- a tool spindle (3) that is positioned in a stand (2) that defines and delimits a machining space (6),
- a workpiece manipulator (4) within the machining space (6), for supporting a workpiece and workpiece support (5) while the workpiece is machined by the tool spindle (3), with which workpiece manipulator (4) the workpiece and workpiece support (5) can be moved relative to the tool spindle,
- wherein the stand (2) includes a plurality of side walls (7) that delimit the machining space (6), the plurality of side walls including a side wall that has an opening therethrough, wherein a loading door (8) having two opposed side panels (9) is provided so as to pivot about a horizontal pivot axis (12) to open and close the opening, and
- wherein a respective workpiece support holder (10), which is equipped with a respective coupling (11) for coupling to a respective workpiece support (5), is disposed on both of the loading door side panels (9) such that when the opening is closed by the loading door (8), one of the workpiece support holders (10) and its respective workpiece support (5) is located at a transfer position within the machining space (6) while the other of the workpiece support holders (10) and its respective workpiece support (5) is located at a loading position outside the machining space (6), and such that pivoting of the loading door (8) about the horizontal axis (12) is configured to move the one workpiece support holder (10) and its respective workpiece support (5) to said loading position and to move said other of the workpiece support holders (10) and its respective workpiece support (5) to said transfer position;
- and
- wherein, from said transfer position, a given one of the workpiece supports (5) and its corresponding workpiece are transferred from the corresponding respective workpiece support holder (10) to the workpiece manipulator (4), for the machining of the corresponding workpiece by the tool spindle (3).
