Abstract
A clamping device includes a first clamping segment which has a first mounting flange and a tubular member extending axially away therefrom. A first bore extends through the first mounting flange and the tubular member. The first mounting flange is configured for attachment to a rotatable spindle of a machine tool. The clamping device includes a draw bar assembly which has an axially extending elongate shaft. The elongate shaft extends through the first bore of the first clamping segment. A biasing unit is mounted on or in the tubular member. A locking member is removably secured to the elongate shaft such that the biasing unit is compressed between the locking member and a portion of the first clamping segment. The biasing member remains compressed when the first clamping segment is separated from the spindle of the machine tool.
