ABSTRACT:
A portable leveling vacuum tool to align a substantially flat top surface of a plurality of workpieces in a coplanar orientation. The vacuum tool includes a pair of parallel frame rails spaced apart from each other to define an intermediate area therebetween. The frame rails have substantially flat, coplanar bottom surfaces that define a planar reference surface against which the top surfaces of the workpieces are positioned. One or more vacuum cup assemblies are movably mounted to the frame rails using a support plate adjustably movable along the length of the frame rails to separably retain the frame rails adjacent to one another and allow selective longitudinal positioning of the vacuum cup assemblies along the frame rails. The vacuum cup assemblies each have a vacuum cup positioned in the intermediate area and adapted to engage a top surface of a workpiece to hold the workpiece against the reference surface. The vacuum cup is movable in two directions relative to the support plate, and moveable in three dimensions relative to the frame rails. Stiffening members are connectable to the frame rails to inhibit flexing of the frame rails.
