COOPERATING BOLSTER AND FIXTURE CONSTRUCTION FOR QUICK-CHANGE FIXTURING Abstract of the Disclosure A machine tool bolster includes a horizontal fixture support plate and a pressure-operable clamp device is vertically shiftably mounted to the underside of the plate and includes a clamp insert holder extending axially into a circular hole provided in the plate. A fixture is mounted to a locating plate provided with a receptacle adapted to receive the clamp insert holder when the clamp device is raised relative to the plate. A rod is connected to a piston of the clamp device and extends vertically through the holder. The upper end of the rod is conically shaped and acts against complementary shaped clamp inserts radially slidably mounted in the holder to shift them outwardly against a conically flared portion of the locating plate receptacle so as to clamp the fixture to the bolster.
