Claims28
A clamping device for a tool or a workpiece, comprising at least one chuck and at least one holder for the workpiece or the tool, wherein the holder has an upper part and a hollow tubular extension, and the upper part is detachably connected to the hollow tubular extension such that the hollow tubular extension remains hollow when connected to the upper part, wherein the upper part defines a flat upper surface for the tool or the workpiece, wherein the chuck defines a circular opening for receiving the hollow tubular extension of the upper part, and wherein the detachable connection of the upper part of the holder to the hollow tubular extension is a bayonet connection, whereby the bayonet connection is designed to lessen or eliminate undesirable lateral forces during clamping, wherein the at least one chuck has x-y references and z references which, in clamping operation, cooperate with corresponding means of the holder.
A clamping device for a tool or a workpiece, comprising at least one chuck and at least one holder, wherein the chuck has x-y references, which cooperate with a bottom face of the holder, wherein the holder has an upper part and a hollow tubular extension, the upper part being detachably connected to the hollow tubular extension, wherein the clamping device has an inner chuck and an outer chuck, the inner chuck being fixedly connected concentrically to the outer chuck, wherein the x-y references of the holder are configured as elastic inner and/or outer tongue pairs, wherein a hollow tubular extension clamps to the inner and/or outer chuck, wherein an external diameter D of the hollow tubular extension lying in the order of magnitude of an internal diameter D′ of a continuous opening of the inner chuck up to an external diameter D″ of the inner chuck.
A clamping device for a tool or a workpiece, comprising at least one chuck and at least one holder for the workpiece or the tool, wherein the holder has an upper part and a hollow tubular extension, the upper part being detachably connected to the hollow tubular extension, wherein the at least one chuck comprises an inner chuck and an outer chuck, the inner chuck being fixedly connected, concentrically, to the outer chuck, and wherein at least one of the inner chuck and the outer chuck have x-y references and z references which, in clamping operation, cooperate with corresponding means on the holder, and wherein the chuck defines a circular opening for receiving the hollow tubular extension of the upper part.
