METHOD AND APPARATUS FOR FORMING RIVET JOINTS

摘要

A method and apparatus (20, 90) for forming rivet joints that allow pivotal motion of the parts interconnected by such joints with a desired amount of clearance (86). Parts (66, 68) to be riveted together are aligned with ea ch other and held in place on a parts support anvil (24, 96), and a rivet (74) is placed into aligned holes (70, 72). A rivet support anvil (38) is positioned against the head (76) of the rivet to establish an initial condition. The rivet support anvil is adjusted a required amount with respect to the parts suppor t anvil prior to formation of the second head (84) on the opposite end of the rivet. The rivet is allowed to move a controlled amount prior to formation o f the second head, to provide the desired amount of clearance.
