Abstract
A clamping nosepiece for a hardness tester is disclosed. The clamping nosepiece is removable from the tester and includes means to adjust the position of the penetrator with respect to the clamp. Additionally, the amount of clamping force with which the clamp holds the workpiece is also adjustable. Belleville washers having a stiff gradient are employed to exert the clamping force, and linear ball bearings are employed to minimize frictional hysteresis which can occur in prior clamping nosepieces.
