Abstract

A rotary clamp having an adjustable pre-stop wherein the rotary clamp includes a linear actuator for transmitting linear motion to a linkage assembly. The linkage assembly converts the linear motion into rotary motion of a clamp arm, wherein the clamp arm moves between a clamped position and an unclamped position. The adjustable pre-stop provides a substantially cylindrical member having a substantially polygonal shaped surface formed on the cylindrical member. The polygonal surface matingly engages a substantially polygonal shaped aperture formed in the housing of the rotary clamp. An eccentric mid-portion of the cylindrical member engages the linkage assembly in the clamped position to prohibit the clamp arm from rotating beyond the clamped position. The eccentric mid-portion provides a plurality of predetermined radial distances extending from the longitudinal axis corresponding to predetermined rotational positions of the hexagonal surface relative to the hexagonal aperture, wherein the predetermined radial distances correspond to predetermined incremental angular adjustments of the clamp arm in the clamped position.
