Abstract: An apparatus is provided for aligning and securely positioning at least two components relative to each other, comprising a support frame, first and second alignment plates pivotally mounted on the support frame for abutment by the components to permit positioning of the components of various angles relative to each other, and a vacuum device for holding a component against the respective plate. The vacuum device may include first and second flexible vacuum pads corresponding to the plates, a respective vacuum pump associated with each alignment plate and a control valve for selectively controlling the flow of supply air to the vacuum pumps. A locking device may be provided for preventing relative pivotal movement of the plates by securing the plates in a predetermined alignment position. The alignment and securing apparatus of the present invention can be used to easily, quickly and securely position two components in a variety of relative orientations.
