Abstract
A workpart fixture for an unbalanced drill bit lug includes a support having a vee-shaped recess with an included angle substantially the same as vee-shaped intersecting surfaces on the drill bit lug to receive same and a fluid actuated clamp assembly carried on an arcuate slide which is movable in a circular arc path laterally relative to the drill bit lug generally about a centerline through the drill bit lug body to accommodate right or left linear or angular offset of the line of intersection of the vee-shaped lug surfaces and to optimize clamping force on the lug in the fixture. The clamp assembly includes a clamp lever which is pivotal toward and away from the drill bit lug by a fluid actuator and which carries swiveling clamp pads that seat against the drill bit lug when the clamp lever is actuated by the cylinder.
