Abstract:
A Machine tool comprising:a tool spindle (1; 1â€²) rotatable about a spindle axis (1a); a tool exchanger including at least one pivotable gripper (2; 2â€²) for displacing tool holders (4) or tools between a receiving position in the tool spindle (1; 1â€²) and a storage position or vice versa, and whereby the orientation of the tool holder (4) or tools in the receiving and storage positions is identical, and wherein the storage position and receiving position are displaced with respect to each other along the direction of the spindle axis (1a) of the machine tool (1; 1â€²); and a transport mechanism that includes a driven inclined carrier element (3; 3â€²) rotatable about a pivot axis (5) inclined to the spindle axis (1a), to which carrier element (3; 3â€²) and the at least one pivotable gripper (2; 2â€²; 2â€³) are connected about mutually-perpendicular axes, and wherein guide elements (10) are included on and driven by said carrier element (3; 3â€²) that include a central drive gear wheel (3a), said carrier element (3; 3â€²) being mounted so it may rotate about a first axes (8) that is parallel to the pivot axis (5) in the direction opposite to a pivoting movement of the carrier element (3; 3â€²) about the pivot axis (5), each of these first axes (8) being connected to said at least one gripper (2; 2â€²; 2â€³) rotating about second axes (9) extending parallel to the spindle axis (1a).
