ABSTRACT:
An adjustable base assembly for selectively adjusting the horizontal and vertical position of a fabricating tool such as a punch or metal forming tool. The apparatus includes a generally planar base and a carriage assembly positioned on the base. The carriage assembly includes a lower wedge plate assembly having an upper surface defining a pair of upwardly converging wedge faces, an upper wedge plate assembly having a lower surface defining a pair of downwardly converging wedge faces, a pair of wedge blocks each having converging upper and lower wedge faces for respective sliding engagement with one of the upwardly converging wedge faces and one of the downwardly covering wedge faces, and a vertical adjustment screw mounted on the lower wedge plate, passing through the wedge blocks, and including left and right threaded portions for respective threaded coaction with a left threaded bore in one of the wedge blocks and a right threaded bore in the other wedge block. Rotation of the screw moves the wedge blocks toward or away from each other to raise or lower the upper wedge plate relative to the lower wedge plate. The carriage is moved horizontally relative to the base plate by a horizontal adjustment screw passing through a threaded bore in the lower wedge plate with the horizontal movement of the carriage on the base plate being facilitated by linear roller bearings interposed between the base plate and the lower wedge plate.
