Abstract:
Fastening device for fastening a work on a machine tool, comprising a palette defining an exterior generally flat surface, said palette having a bore defining a bore axis generally normal to said flat surface; a generally elongate draw-in nipple defining a nipple axis and having one end portion received within said bore and having an opposing end portion extending outwardly beyond said flat surface; and retaining means on said palette for retaining said one portion within said bore and forming selected clearances about said one end portion when no tension or pulling forces are applied to said opposing end portion and for substantially eliminating said clearances when tension or pulling forces are applied to said opposing end portion to lock said draw-in nipple with said bore and nipple axes in substantial alignment, whereby said clearances are only eliminated upon application of a tension or pulling force on said draw-in nipple acting along said axes, said draw-in nipple being permitted to experience limited movements in relation to said bore axis only prior to application of tension or pulling forces.
