A circular tool magazine for carrying a plurality of tools in a horizontal attitude is provided on a support base which is positioned above the region in which the mobile column moves. The support base is supported in a cantilever fashion by posts erected on a bed. The tool magazine rotates within a horizontal plane for indexing tools to a standby position. The tools are accommodated in pots suspended via rolling members from the body of the tool magazine and adapted to move along a ring-shaped path under the tool magazine body. The tool magazine body has a local removal opening or cutout, from where a shifter at a standby position carries a pot to a tool delivery position.

Abstract: The machine tool comprises a machine stand (10) with a vertically movable vertical carrier (12) carrying a spindle head (SK1) for treatment of a workpiece. To exchange the spindle head (SK1) against a new spindle head (SK2), an exchange unit (15) is provided, comprising an exchange arm (16) pivotable by 90.degree. about a vertical axis (37). Two holding couplings (17,18) are mounted above each other on the exchange arm (16), each adapted to carry a spindle head (SK1,SK2). A delivery means (21), gripping the spindle heads from above, is used to supply the spindle heads for transfer to the exchange unit (15). The exchange unit (15) grips the spindle heads from the side. By pivoting the exchange arm (16) over 90.degree., the spindle head is pivoted to a position in front of the machine stand (10) and thus can be taken over by the vertical carrier (12).

Abstract: A machine tool comprises a tool exchanger for exchanging tools between a vertical-axis spindle and a load/unload position of a tool magazine. The load/unload position is located, in a front view of the machine tool, above the spindle and laterally offset therefrom. The tool exchanger, further, comprises two exchanger arms operating reciprocally, each contributing to conveying a first tool from the spindle to the load/unload position and, simultaneously, a second tool from the load/unload position to the spindle. The exchanger arms are each rotatable about one separate axis only. Each of the exchanger arms exchanges its associated tool between the spindle and one separate transfer position each. The two transfer positions associated to the two exchanger arms are located at different distances in front of the load/unload position on the tool magazine. Further, a transfer device is provided for transferring the tools between the load/unload position and, alternately, one of the transfer positions.

Abstract: A simple and efficient tool exchanger device is presented. The device has a pair of swing arms (8, 9), and each swing arm is provided with a set of grippers (11, 12) for holding a tool bit. The positions of the swing arms (8, 9) are separated by 90 degree so that they will not interfere with each other during the swinging motion. One driving device (2) is provided to operate both swing arms (8, 9) and operate the gripper devices (11, 12). The swing arm (8) rotates upwards to remove a used tool bit (10) from the machining shaft (21) of a machining center and the other swing arm (9) is rotated downwards to install a new tool bit (10') in the vacated machining shaft in a single simultaneous step.
