ABSTRACT:
A clamping fixture for rectangular workpieces is formed by a pair of oppositely directed cylindrical chuck jaws, each mounted so as to be freely rotatable about a longitudinal axis. Each of the chuck jaws has a cut-out sector extending along its length, which forms a seat for the workpiece and which is defined by a pair of extending surfaces set at right angles to each other and intersecting in a common edge extending co-axially with the axis of rotation of the chuck jaws. Each of the chuck jaws is provided with a longitudinal slot extending inwardly from the intersection of the seat surface and terminating short of the opposite wall, so as to provide an integral web connecting the seat surfaces.
