SURFACING MACHINE TOOL Russian patent published in 2005 - IPC

FIELD: machine engineering, namely apparatuses for surfacing at restoring defective or damaged parts.

SUBSTANCE: surfacing machine tool includes column with yoke, cross piece, carriage, face chuck, table with adjustable inclination angle, surfacing head having mechanism for reciprocation motion in horizontal plane, mechanism for vertically moving surfacing head, mechanism for rotating in horizontal plane surfacing head with mouthpiece. On surfacing head there are mounted: reel with surfacing wire, mechanism for feeding wire to surfacing zone through mouthpiece and mechanism for reciprocation motion of surfacing head in horizontal plane. Machine tool is provided with matching device having actuating organ and providing kinematic connection between mechanism for rotating surfacing head and mechanism for vertical motion of surfacing head. Handle and flywheel kinematically joined with toothed rack of cross piece are secured to carriage. Matching device is in the form of worm reduction gear of rotation mechanism that is kinematically joined through first cone reduction gear with face chuck and through set of gear wheels - with connection coupling. The last through spring of actuating organ in the form of electromagnet and through second and third cone reduction gears is joined with lead nut of vertical motion mechanism.

EFFECT: enhanced operating efficiency, enlarged functional possibilities of machine tool.
