1. A multi-station fixture vise for simultaneously clamping a plurality of workpieces, said vise comprising:
a) a base including a base plate, b) a vise screw comprising a cylindrical body having a diameter and a length extending from a first end to a second end, and a head located at said first end wherein:
i) the body is threaded along at least a portion of its length, the diameter of the unthreaded portion of the body being the same as the diameter of the threaded portion, andii) the head has a diameter greater than the diameter of the threaded portion of the body and is configured to engage with an external tightening tool, c) one fixed jaw having at least top and bottom faces, parallel front and back faces perpendicular to said bottom face, and left and right side faces, said fixed jaw fixably attached at said bottom face to said base plate and having first and second clamping surfaces disposed on said front and back faces of said fixed jaw, respectively, wherein:
i) two guide rods are fixably mounted on each clamping surface perpendicular to each clamping surface,ii) a clearance hole for said vise screw is drilled through said fixed jaw perpendicular to the clamping surfaces, andiii) clamping features are attached to or machined into each clamping surface, d) a first movable jaw having a clamping surface arranged parallel to said first clamping surface of said fixed jaw, wherein:
i) two clearance holes are drilled through said first movable jaw perpendicular to said clamping surface, said clearance holes being disposed to admit said guide rods mounted to said first clamping surface of said fixed jaw and allowing said first movable jaw to slide on said guide rods,ii) a third clearance hole for said vise screw is drilled through said first movable jaw perpendicular to said clamping surface, said clearance hole being disposed to align with the clearance hole drilled in said fixed jaw when said first movable jaw is mounted on said guide rods, andiii) clamping features are attached to or machined into said clamping surface, e) a second movable jaw having a clamping surface arranged parallel to said second clamping surface of said fixed jaw, wherein:
i) two clearance holes are drilled through said second movable jaw perpendicular to said clamping surface, said clearance holes being disposed to admit said guide rods mounted to said second clamping surface of said fixed jaw and allowing said second movable jaw to slide on said guide rods,ii) a third hole is drilled through said second movable jaw perpendicular to said clamping surface and tapped to engage with said vise screw, said tapped hole being disposed to align with the clearance hole drilled in said fixed jaw when said second movable jaw is mounted on said guide rods, andiii) clamping features are attached to or machined into said clamping surface, f) wherein said vise screw is inserted through said clearance hole in said first movable jaw, through said clearance hole in said fixed jaw, and threaded into said tapped hole in said second movable jaw, g) wherein a first compression spring having a length and a stiffness is installed coaxially on said vise screw between said first movable jaw and said fixed jaw, and a second compression spring having a length and a stiffness is installed coaxially on said vise screw between said fixed jaw and said second movable jaw, h) wherein the lengths and stiffnesses of said first and second compression springs are equal and the lengths are adjusted to be under slight compression when said vise screw is threaded into said second movable jaw, and i) wherein axial motion of said vise screw causes first and second movable jaws to move towards each other or away from each other. |
