ABSTRACT:
A machine tool includes a table (24) movable in a first direction and a second direction for supporting a work holder (H), a work storage magazine (3) for storing a plurality of work holders (H), and a work changer for transferring work holders (H) between the work storage magazine (3) and the table (24). The axis of the work holder (H) supported in the table (24) is directed in a horizontal direction. Each axis of the work holders (H) stored in the work magazine (3) is directed in a vertical direction. The work changer (5) comprises: a frame (70); a vertical shaft (71) fixedly mounted on the frame (70), the vertical shaft (71) having a first bevel gear (74) fixed thereto; a casing (72) rotatably supported on the vertical shaft (71); a drive device (76-78) for rotating the casing (72) about the vertical shaft (71); a horizontal shaft rotatably mounted on the casing (72), the horizontal shaft having a second bevel gear (83) engaging with the first bevel gear (74); a finger frame (80) connected to the horizontal shaft (8); a finger unit (5a) mounted on the finger frame (80) and rotatable about its rotation axis, the finger unit (5a) having two pairs of fingers (86b, 86a) each of which grips a work holder (H), the two pairs of fingers (86b, 86a) being arranged symmetrically about the rotation axis of the finger unit (5a); and a drive device for rotating the finger unit (5a). The gear ratio of the second bevel gear (83) to the first bevel gear (74) is 2/1 so that when the casing (72) is rotated about the vertical shaft (71) by 180 degrees the second bevel gear (83) is rotated by 90 degrees.
