Two station vise for manual or hydraulic operation with a quick-change stationary that can be carvable, hard or reversible. the stationary jaw having two precision through holes is placed on expanding pins, located on the top longitudinal rails of the vise body, that precisely position and tighten the stationary block in place. Two movable jaws connected by a tubular drive form an axially adjustable floating assembly. A manually turned tubular drive has an external threaded screw to move simultaneously the first jaw/nut and an internal thread that moves the second jaw/nut, on the opposite side of the stationary. Hydraulically parts are clamped at the two stations with a piston located in the second jaw/nut and connected axially with the first jaw/nut by the tubular drive. A setup-block located at the front jaw/nut keeps both jaws at proper position for loading and unloading of parts. The setup-block also allows for pre-clamping or retention of the part in the rear station before clamping.
A two station vise comprising a vise body, a longitudinal recess formed in said body, a stationary center block mounted in center portions of the body, a floating double vise jaw assembly mounted in the recess, said double jaw assembly including a first vise jaw nut and a second vise jaw nut, a vise screw including a first tubular section having an outer surface threadably engaged with the first vise jaw nut, and having interior base with internal threads, a second vise screw section threadable into the internal threads of the first vise screw section, the second vise screw section being connected to the second vise jaw nut such that tension on the second vise screw section causes movement of the second vise jaw nut toward the center block at the same time the first vise jaw nut is threaded toward the center block from an opposite side thereof.
A vise having a vise body, the vise body having a pair of rails that are spaced apart and which extend longitudinally, a center stationary block mounted on said vise body and extending across the rails, and a pair of moveable vise jaws slidably mounted relative to the rails, a first vise jaw being on a first side of the center block and a second vise jaw being on an opposite second side of the center block, a first vise jaw nut having a head engaging the first vise jaw, a second vise jaw nut having a head engaging the second vise jaw, a vise screw assembly including a first vise screw section threadably connected to said first vise jaw nut with threads on the exterior of the first vise screw section, and a second vise screw section connected to said second vise jaw nut to provide a tension carrying connection between the second vise screw section and the second vise jaw nut, said second vise screw section being threadably mounted into an interior bore of the first vise screw section, and the threads on the exterior of said first vise screw section and on the interior of the bore of the vise screw section being such that upon rotating the first vise screw section in one direction, both the first and second vise jaws are moved toward the center block, and when rotated in an opposite direction, the first and second vise jaws both move away from the center block.
