Patent ID: 8191879

Claim:
A vise pad for accurate work piece alignment comprising: a) an internal member comprising at least two cam grooves formed longitudinally over the outer surface of said internal member, at least two cam grooves formed crosswise and perpendicular to said at least two longitudinal cam grooves, and a plurality of drilled screw grooves; b) an external member comprising at least two cam grooves formed longitudinally over the inner surface of said external member, at least two cam grooves formed crosswise and perpendicular to said at least two longitudinal cam grooves, and a plurality of drilled bolt grooves corresponding to said plurality of screw grooves; c) at least two wedge bars held parallel to each other by two or more connectors each having at least two rounded holes wherein said wedge bars fit through corresponding rounded holes of the connectors, thereby forming a wedge bar-connector combination, d) at least two bolts coupled to the screw grooves through the bolt grooves to maintain a coupled state of said internal and external members; and wherein said pad is assembled by bringing said internal member into contact with said external member such that said respective longitudinal and crosswise cam grooves face together, capturing said wedge bar-connector combination, and screwing said at least two bolts through said at least two bolt grooves into said at least two screw grooves.
