Self-centering clamp
A clamping device is configured to ensure that a workpiece fixed between the jaws of the clamp is self centered by coupling the jaws to a pair of linkages that rotate through the same angle as the application of a first causes the jaws to translate in linear fashion across the surface of the device. In particular, the clamping device utilizes coupled linkage (e.g., a 180° bell crank), in combination with slots for retaining opposing jaws and maintaining only linear movement of the jaws, thus providing a fast and accurate self-centering arrangement.
