Abstract:
1. A clamping driver system for incorporation into a host clamping device as a portion, located at a first end thereof, that includes a movable clamp jaw co-operating with a fixed clamp jaw of the host clamping device, located at a second end thereof, to securely clamp a workpiece therebetween, said clamping driver system comprising: a lever having a first end region pivotally mounted on a lever pivot pin secured in a base mechanical node in common with the host clamping device, said lever extending to a second end region for user actuation, constrained to a working range of rotation approximating 90 degrees; a cam formed integrally as a portion of said lever in the first end region thereof; a compressible drive subassembly, comprising: a solid lever-driven component receiving driving force and displacement from said cam: a compressible drive component having a resilient thickness between a first side surface thereof held in operational contact with said solid lever-side driver component; and a second and opposite side surface thereof; a solid driver component, receiving the driving force and a portion of the displacement from the second side surface of said compressible drive component; configured to constitute the movable clamp jaw; whereby, a user, manipulating said lever to a first end of the working range, is enabled to initiate a disengaged mode wherein a workpiece of designated dimensions and tolerances can be readily and rapidly relocated between a removed location and a clamping location, regardless of dimensional variations in the workpiece including those due to the tolerances, such variations being compensated by variations in the resilient thickness of said compressible drive component; and whereby, upon user manipulating said lever to a second and opposite end of the working range of rotation, is enabled to initiate an engaged mode wherein the workpiece is held securely clamped in place, between the fixed jaw and the movable jaw, by at least a designated required substantial amount of compressive clamping force, regardless of dimensional variations in the workpiece, due to the tolerances, such variations being compensated by variations in the resilient thickness of said compressible drive component.
