Abstract
1353886 Chucks PAUL FORKARDT GmbH 4 April 1972 [15 April 1971] 15294/72 Heading B3B A multi-jaw chuck for a high speed machine comprises an axially displaceable clamp piston 2 in the interior of a chuck body 1, the displacement of which effects a radial movement of bottom jaws 9 carried in clamp grooves 24 of the chuck body, the transfer of force taking place from the piston to the bottom jaws via angle levers 7, characterized in that each angle lever is arranged in the bottom jaw so as to be pivotable about a bearing pin 8 in the bottom jaw, a long arm 10 of each angle lever engaging in the piston, a short arm 12 being inserted in a pivot pin 14 carried in a through bore 13 in the chuck body. Thus axial movement of the piston causes radial movement of the bottom jaws. Actuation of the piston is by a draw bar. A clamp jaw 15 is attached to each bottom jaw.
