Patent ID: 7543519

Claim:
A device for high precision generation and measurement of forces and displacements along a single axis X, having great rigidity in an axis Y perpendicular to the axis X, the device comprising: a) a shaft for transferring the forces; b) at least two first leaf springs attached to said shaft, wherein said at least two first leaf springs are clamped at each end and biased in a direction toward the axis Y; c) a first closed frame movably mounted to a rack with at least two second leaf springs, wherein said at least two first leaf springs are clamped in said closed frame; and d) a first bracing element for adjusting a bias of said at least two first leaf springs said first bracing element comprising a first clamping strap; a first clamping plate; a first adjusting screw for clamping a first end of one of said at least two first leaf springs between said first clamping strap and said first clamping plate; and a first straining screw for adjusting said first clamping plate against said closed frame in a direction along the axis Y to bias said leaf spring clamped between said first clamping strap and said first clamping plate in a longitudinal direction along the axis Y.
