Cacuum clamp device to vacuum clamp device

An apparatus for securing a first structure to a second structure and performing an operation on the first and second structures, the apparatus comprising:

• a frame structure;
• a plurality of suction cups coupled to the frame structure, the suction cups operable in an energized mode that is adapted for securing the apparatus to the first structure;
• and
• at least one clamp assembly coupled to the frame structure, the at least one clamp assembly including a fluid power cylinder having a rod that is movably coupled to the frame structure, the fluid power cylinder being operable in a first mode for moving the rod toward the second structure and exerting a clamping force, the clamping force being adapted to retain a mating surface of the second structure against a mating surface of the first structure, the fluid power cylinder also operable in a second mode for moving the rod away from the second structure.
