ABSTRACT:
A power operated clamp includes a cylinder having a reciprocal piston rod. A hollow clamp body having side plates is aligned with and connected to the cylinder. A clamp arm is pivotally mounted upon the body and in one position is adapted to retainingly engage a workpiece relative to a workpiece support. A linkage is pivotally connected to the clamp arm; the improvement which comprises a series of vertically spaced pairs of longitudinally spaced transverse mount holes extending through the side plates. The mounting of the body includes an upright riser extending between the side plates and has a series of longitudinal similarly spaced apertures corresponding to some of the side plate apertures. Pivot bolts extend through some of the mount holes and riser, whereby the body may be mounted selectively in one of a plurality of longitudinal locations above or below the riser. A rod end is guidably mounted within the body and axially connected to the piston rod. A pivot slide pin supportably extends transversely through the rod end and at its ends is slidably mounted within side plate slots. The linkage includes a pair of links interconnecting the rod end and clamp arm. An eccentric pre-stop spans, is rotatively adjustable and secured to the side plates and is spaced from the clamp arm adapted for retaining engagement with the clamp arm when moved to workpiece retaining position.
