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.

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.

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.

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.

Abstract: A modular clamping system for fixturing workpieces with respect to a numerically controlled drilling and boring machine or the like includes a pair of soft jaw blocks which may be variably spaced with respect to one another in fixed positions to hold the workpiece therebetween. A vice assembly preferably holds the soft jaw blocks in a fixed position during use by way of several vertical and horizontal alignment mechanisms. Cavities to hold the workpieces in place are machined in the soft jaw blocks by the NC machine prior to each job to accurately reference the workpiece with respect to the NC machine.

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.

Abstract: A tool capable of applying clamping forces or, alternatively, spreading forces to the surfaces of spaced apart articles. The tool includes an elongate tubular base at one end of which is removably mounted a tail stop which serves to impart both clamping and spreading forces to associated articles. Mounted at the opposite end of the tubular base is a boss which is internally threaded to receive the screw shaft of a traveler assembly. The traveler assembly includes oppositely disposed, force imparting members which coact with the tail stop in clamping and spreading operations. Movement is imparted to the traveler assembly by a ratchet wrench on the screw shaft.

Abstract: A workbench has a pair of rigid wooden work plates bridging and fixed to a pair of transverse support elements from which extend legs constituting a foldable stand. The work plates are each formed with a plurality of throughgoing bores into which pegs of a clamp and holding blocks may fit, these pegs being smaller than the bores so that the blocks and clamp tip when acted upon parallel to the work surface. The faces of the blocks and clamp are inclined to be perpendicular to the work surface when the pegs are thus tipped. The legs of the stand can fold parallel to each other and flat against the work table when the workbench is not in use.
