1. A powered clamp assembly comprising:
- an actuator;
a cam member having a camming surface;
wherein the cam member is attached to and driven by the actuator;
at least one jaw arm pivotable about an axis;
a bearing member attached to the jaw arm;
wherein the bearing member is engagable with the camming surface of the cam member; and
wherein movement of the cam member causes the camming surface to move the bearing member which causes the jaw arm to pivot.

Abstract
A powered clamp assembly is provided having an actuator, a cam member, a jaw arm, and a bearing member. The cam member has a camming surface and is driven by the actuator. The jaw arm is pivotable about an axis. The bearing member is attached to the jaw arm, as well as being engagable with the camming surface of the cam member. Movement of the cam member causes the camming surface to engage the bearing member which causes the jaw arm to pivot.

9. A powered clamp assembly comprising:
-
a body; an actuator; a cam member having first and second camming surfaces; wherein the cam member is driven by the actuator; a first jaw arm pivotally mounted with respect to the body; a second jaw arm pivotally mounted with respect to the body, and positioned opposite the first jaw arm; a first bearing member attached to the first jaw arm and engagable with the first camming surface of the cam member; and a second bearing member attached to the second jaw arm and engagable with the second camming surface of the cam member; wherein movement of the cam member causes the first and second camming surfaces to engage the first and second bearing members, respectively, to cause the first and second bearing members to move to cause the first and second jaw arms to move. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A powered clamp assembly comprising:
-
an actuator; a cam member having a camming surface which forms a pathway along at least a portion of the outer periphery of the cam member; wherein the cam member is driven by the actuator in first and second directions; a link movably coupled to the cam member; a jaw arm; and a bearing member coupled to the jaw arm; wherein the link is movably coupled to the jaw arm; and wherein during movement of the cam member in the first direction, the camming surface engages the bearing member and moves it along the pathway which causes the jaw arm to move. - View Dependent Claims (20, 21)

22. A powered clamp assembly having at least two jaw arms, with at least one of which being pivotable with respect to the other at a pivot point, and an actuator having a rod extending therefrom which is movable rectilinearly, the powered clamp assembly further comprising:
-
a wedge that is coupled to the rod for rectilinear movement; a bushing coupled to the at least one jaw arm wherein the wedge engages the bushing on the at least one jaw arm at a location spaced apart from the pivot point to move the at least one of the jaw arms about the pivot point.
