A compact, portable, fully automated rivet installation system for a fraction of the cost of large stationary systems is presented. Hand assembly is still being done in many areas where automated equipment could be used to improve quality and productivity. One such application is minor subassemblies such as clips, brackets etc. that often have fewer than ten or twelve rivets. The system presented is fast, reliable, self contained and can process a wide range of parts. Operation of the system and application of each style of “C” frame are discussed.

A drill and rivet machine with a unique dual lower ram has been designed and built. The dual lower ram assembly consists of two horn shaped rams that are mounted at ninety degree angles to one another. Both rams remain operational at all times. When one ram is in place in the front of the machine the other ram is pivoted out to the side of the machine. Each ram has a unique horn shape and carries its own offset lower anvil assembly. The unique horn design allows the ram to reach into high curvature leading edge parts. The operator can select either ram so that a complete ship set of high curvature parts can be produced by the machine with no other tool changes required.
