Method and means for measuring squareness of plate structures

Abstract

An apparatus and method for measuring the squareness of fabricated plate structures by providing a measuring table having a straight reference gauge extending squarely across the table, and a plunger-operated measuring gauge rigidly mounted on a carriage which is slidably mounted to the underside of the table so as to slide the plunger at right angles to the reference gauge, positioning the plate on the measuring table with a first edge abutting the straight reference gauge, retracting the plunger, moving the carriage which holds the measuring gauge to a position in front of a second edge of the plate, releasing the plunger slowly until it contacts the second edge, activating the measuring gauge, moving the carriage along the length of the second edge and holding the plunger in constant and continuous contact with the second edge to measure deviations from squareness between the first and second edges with the measuring gauge, moving the carriage and gauge with plunger mounted thereon clear of the plate, and repeating the above steps as needed to determine the squareness of other plate edges.
