  • Workpiece positioning vise
    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.
