ABSTRACT:
A fixture assembly for use in conjunction with a vehicle frame straightening rack. The assembly is adjustable to accommodate any model of vehicle, adjustments being possible in both fore and aft as well as side to side directions and in height. An adjustable clamping fixture is incorporated into the assembly to hold the frame on the straightening rack. In use, the vehicle frame to be straightened is supported on the straightening rack. One side is aligned at the fixturing points provided in the vehicle frame by use of an alignment fixture at one end of an alignment beam. The opposite side is then similarly aligned at the opposing end of the alignment beam with a similar alignment fixture. A ruler is provided on the alignment beams to aid in the precision of placement of the alignment fixtures. Clamping fixtures are then attached and all the fixtures are locked in place. As the frame is then straightened the fixtures remain engaged with the frame and precise alignment is accomplished. After the frame is aligned at the first set of fixturing points, the procedure is repeated as necessary at subsequent fixturing points to provide complete alignment of the vehicle frame.
