  • Patent number: 8141859
    Abstract: An apparatus and method for separating a pin tool from a shoulder tool, after the pin tool and shoulder tool have become welded together during a friction stir welding operation. In one exemplary embodiment a frame is used to support the shoulder tool. A fluid pressure actuating assembly is used for gradually exerting a force on the pin tool while the shoulder tool is held stationary within the frame. The gradually increasing force gradually breaks the weld and separates the pin tool from the shoulder tool without damaging the pin tool.

  • Publication number: 20090283951
    Abstract: A clamping jaw includes an unthreaded rod receiver and a swing nut assembly including a swing nut lever and threaded nut coupling integrated thereon. An adjustment knob includes an adjustment knob collar fixed onto a second end of the threaded rob opposite said shaft collar. An idle jaw includes an unthreaded shaft collar adapted to receive and fit over a second end of the threaded rod. The swing nut is operable to interface the threaded nut coupling with the threaded rod held within the unthreaded rod receiver of the clamping jaw and move along the threaded rod by rotation of the adjustment knob while the idle jaw mounted on said threaded rod between the clamping jaw and the adjustment knob remain stationary next to the adjustment knob. The clamping jaw is freely movable along the threaded rod by disengagement of the swing nut and then by rotation of the adjustment knob when the swing nut is engaged with the threaded rod.

  • Patent number: 6409162
    Abstract: In accordance with this invention an eccentrically immobilized hinge-type device is provided having a yoke shaped hinging element with cylindrical peripheral surfaces and a channel shaped hinging element with an eye-ended connecting rod, and a relatively eccentric hinge-pin. The cylindrical peripheral surfaces of the yoke shaped hinging element seats in the channel shaped hinging element and both elements pivot on the relatively eccentric hinge-pin which penetrates the bore of the yoke and the eye-end bore of the connecting rod. The eccentric hinge-pin is connected to an activating means that controls the eccentrically applied tension on the connecting rod, consequently the friction between the cylindrical peripheral surfaces of the yoke shaped hinging element and the seat of the channel shaped hinging element, thus affecting hinging ability.

  • Patent number: 5222330
    Abstract: The disclosed fixture has a main clamping piece defining several differently sized smooth bores, the locations and sizes of which are selected to receive and hold different central mounting mechanisms of incompatible cutting tools, with the intended cutting edge on each cutting tool then spaced beyond and clear of the clamping piece. A stop is provided in accurate vertical registry with each bore, allowing the fixture to be secured to a grinder bed and located accurately relative to the grinding wheel, before the cutting tool is mounted thereon and any sharpening begins. Before being tightened down, the cutting tool can be rotated selectively in the fixture to accurately set where the grinding wheel will sharpen the cutting edge, and a second clamping piece then secures the cutting tool rigidly in the fixture. Special mounting pins cooperate respectively with the different cutting tool central mounting mechanisms to hold the different cutting tools relative to its proper fixture bore.

  • Patent number: 4653740
    Abstract: An apparatus for the quick clamping of skis of various widths is described, having two parallel guide rods on which a movable clamping jaw is guided. By means of a threaded element and an eccentric lever, the movable clamping jaw is reciprocated in the axial direction and relative to a stationary clamping jaw. In order to attain a substantially constant clamping force with such an apparatus while providing for easy manipulation, a threaded spindle, as the threaded element, is rotatably supported and is joined in a rotationally stiff manner with the eccentric lever via a member which is elastic in the axial direction.

  • Patent number: 4448406
    Abstract: A workpiece holding vise (10) uses a pair of jaw assemblies (12, 14) simultaneously driven in opposed reciprocation by a single shaft (26) having oppositely threaded sections to automatically center a workpiece (60) beneath a tool. Both jaw assemblies (12, 14) are suspended above the vise bed (20) by a pair of parallel guide shafts (56, 58) attached to the vise bed. Linear rolling bearings (54) fitted around the guide shafts and firmly held by opposite ends of the jaw assemblies (12, 14) provide rolling friction between the guide shafts (56, 58) and the jaw assemblies (12, 14). A bellville washer (46) at one end of the drive shaft (26) and thrust bearings at both drive shaft ends hold the shaft in compression between the vise bed (20), thereby preventing wobble of the jaw assemblies due to wear between the shaft and vise bed.
