MULTIPURPOSE MACHINE TOOL Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: this relates to machine-tool industry and can be used in machines with automatic replacement of table-satellites. Turning platform of machine has bosses with supporting surfaces, and rigidly installed in them by means of thermoplastic compound are hollow basing taper pins resting on supporting surfaces of bosses. Installed in holes of table-satellite and secured by means of thermoplastic compound are sleeves having taper surface which is mating to basing pins. Sleeves are rigidly connected with table-satellite by fastening member with shank on its end. Interacting with it is fixing device which is spring-biased relative to turning platform and can be displaced inside every taper pin. Rigidly mounted in base according to number of taper pins are releasing devices which can interact with fixing devices, and they are located at guaranteed clearance with respect to fixing devices. Provided in table-satellite are covering guide strips for interaction with clamping plate which is installed on rod of mechanism for lifting and clamping of table-satellite with possibility of self-adjusting. It is provided with guide bars which can displace axially inside bushes. Bushes are rigidly installed in holes made in turning platform. With table-satellite in clamped position, mechanism for lifting and clamping of table-satellite is in released position. EFFECT: higher efficiency. 7 cl, 8 dwg
