    Abstract: A clamping apparatus and method for maintaining a workpiece flatness during processing includes a base having a planar surface for receiving a first workpiece. Two sets of opposing clamping mechanisms are mounted to the base and include a clamp head at a distal end of a rod extending from a housing in removable overlapping relation to the first workpiece. Each set of the clamp heads are in opposing spaced relationship to each other defining a second workpiece area, and the clamp heads are configured to mate with a top surface of the first workpiece. A biasing member is coupled to each of the housings and apply a downward vertical force to the housings, rods, and the clamp heads for applying a downward vertical pressure to the first workpiece. The first workpiece is thereby discouraged from thermally expanding in a vertical direction and is thermally expandable horizontally along the planar surface.

  • Patent number: 5730433
    Abstract: A tool for mating, clamping, and gluing under high pressure, two picture frame members, the ends of which have been precisely cut prior to clamping. This high pressure produces a stronger joint than is now available in existing clamps that only hold the adjacent times while the glue is setting. It also produces a faster glue setting time than conventional clamps since excess glue is squeezed out, thus increasing clamp efficiency by making it available sooner for the next glue joint. In addition, it embodies an optional vertical clamp, which, in conjunction with a transparent triangular plate, applies a vertical pressure on members that may have been slightly warped or inaccurately cut. The triangular plate is optionally used with complex profiles to distribute the pressure. This combination results in a tight aesthetic joint. Existing clamps on the market do not embody this feature.

  • Patent number: 5720476
    Abstract: A removable jaw assembly for a workholding apparatus having a base member with a longitudinal slot therein. The assembly includes a movable support member that has a lower portion operably supportable in the longitudinal slot such that it can be selectively axially moved therein. The movable support member has an upper portion that protrudes from the slot for supporting a jaw member thereon. A jaw retaining member is attached to the upper portion of the movable support member such that it is selectively movable between a first position wherein the jaw member is nonremovably attached to the upper portion of the movable support member and a second position wherein the jaw member can be removed from the upper portion of the movable support member. An actuation member is provided on the base member for biasing the jaw retaining member to the second position when the movable support member is moved to a disengaged position.

  • Patent number: 5467972
    Abstract: A clamping apparatus having a fixed post with a pad and a clamping jaw post with a threaded hole, through which a screw with a handle on one end and a pad on the other passes. The clamping apparatus may be used with rails so that on the bottom rail the fixed post is placed within one hole and the clamping jaw post placed within another hole such that a workpiece may be clamped between the two, and additionally a top rail with holes that the other ends of the fixed and clamping jaw post engage with may be added to prevent the workpiece from buckling when clamping pressure is applied by turning the screw.

  • Patent number: 4930760
    Abstract: A multiple chucking device is disclosed, which is suitable in particular for clamping in grooves of a machine table. The device includes a clamping block, at least one clamping piece, and an end block which are mounted on a pair of guide axles. The clamping block is rigidly supported on the pair of guide axles, and the clamping pieces and the end piece are adjustable in a longitudinally displaceable manner, and may be secured by locking screws that engage the axles. The clamping piece and the end block are equipped with a clamping jaw in the form of a wedge collet, and with a support housing a recess, in which an obliquely downwardly extending tightening screw is located. The screw is tightened by the wedge collet so as to engage and clamp a workpiece.

  • Patent number: 4845899
    Abstract: A cassette type part clamping member holding precision parts of small size to very close tolerances. The parts are clamped in a manner so that they are securely held but are not damaged. The cassette mounts relatively easily made, low cost, and useful reference bar for providing a reference surface against which the parts are clamped and also against which a sensor will operate during an operation such as grinding to insure that a straight grind cut is made. The cassette that holds the part clamping members and the reference bar, and a separate outer cassette holder fixture which provides reference surfaces for supporting the reference bar holding it in position accurately and without affecting the preload on the clamping members is mounted on the tool table. The cassette can be removed from and replaced into the holding fixture without releasing the parts.
