Patent ID: 7434302

Claim:
A replacement device for clamping heads having several clamping jaws, wherein said clamping jaws are separated from one another by radially directed slits and are elastically interconnected, said replacement device comprising: a carrier with outer areas, which extend from a central axis of said replacement device in a radial direction, each outer area having a bearing for one pivoting part for each of said clamping jaws, each said pivoting part having at least one extending portion for radial force and torque-transmitting cooperation with said clamping jaws; and a radially acting force application device for acting on said pivoting parts for pivoting said pivoting parts with a certain axial spacing from said bearing and said extending portions, wherein on pivoting said pivoting part said extending portions are substantially radially further compressed by pivoting about said bearing as a result of said cooperation, wherein one of said pivoting parts is pivoted on a carrier plate that is fixed to said carrier, and wherein an outer area of said carrier is constructed as a projecting arm, wherein on the sides of said arm, close to an end, is fixed in each case one said carrier plate for said pivoting parts, said carrier plates having two parts being angled towards each other.
