PCT No. PCT/EP85/00265 Sec. 371 Date Feb. 7, 1986 Sec. 102(e) Date Feb. 7, 1986 PCT Filed Jun. 4, 1985 PCT Pub. No. WO86/00040 PCT Pub. Date Jan. 3, 1986.The invention concerns a manipulator (1) which is able to automatically receive the tool holder (7), to clamp it and to set it down again, in order thus to make possible a rapid changing of different tools. For this purpose, the last drive element (6) of the manipulator (1) as well as the tool holder (7) are provided with coupling parts (8,9) and with cooperating screw systems (16,17). The manipulator-side screw system (17) is mounted via an operating element (11) for rotation at a second operating element (10) which forms a rotation barrier (13) with the tool holder (7) as the coupling parts (8,9) come together. The screwing process is actuated by rotation of the last drive member (6). The two operating elements (10,11) are furthermore non-rotationally connected through a fixing mechanism (20). This rotation lock is abolished as soon as the rotation barrier (13) between the operating part (10) and the tool holder (7) becomes effective. In this manner it is possible during the screwing process to connect connectors (24) present at the operating part (10) with connector counterpieces (25) provided at the tool holder (7) in order to automatically achieve a transfer of energy, cooling and/or pressure medium.
