ABSTRACT:
An adjustable clamp assembly for use in an automated assembly tool. The clamp assembly includes a column portion and a clamp portion, the column portion being mounted to a support of a jig structure for longitudinal movement relative thereto. The jig supports are spaced apart to receive the components which are to be assembled, and the clamp portions are mounted on the ends of the column portions which protrude into the working envelope between the supports. The column portions are selectively movable relative to the supports so as to adjust the distances by which the clamp portions extend into the working envelope. A threaded shaft is rotatably mounted to the column portion and is rotated by an electric motor so that the shaft interacts with a threaded nut in the column to effect the longitudinal movement. The clamp portion on the end of the column portion has a fixed locating hook and a pneumatically actuated clamping hook which pivots from an open position to a closed position to grip the components to be assembled. The positioning of the clamp assemblies and the operation of the pneumatically actuated clamps is directed by the automated computerized control portion of the assembly machine.
