Abstract:
A method of riveting a plurality of parts together to form an assembly with a predetermined clearance or interference between a rivet and said plurality of parts interconnected by said rivet, comprising:(a) providing a rivet support anvil mounted fixedly on a supporting structure; (b) providing a parts clamp supported movably on said supporting structure; (c) placing a rivet having a preformed first head into a rivet hole extending through said plurality of parts to be riveted together, leaving said preformed first head on a first side of said plurality of parts to be riveted together; (d) urging said parts clamp against a second side of said plurality of parts to be riveted together, thereby urging said preformed first head against a rivet support anvil and urging said rivet into said rivet hole and into contact against said first side of said plurality of parts, thereby establishing a reference position of said parts clamp; (e) thereafter urging a parts support anvil from an initial position with respect to said rivet support anvil into pushing engagement with said first side of said plurality of parts, thereby displacing said parts clamp to an adjusted position with respect to said reference position and said parts support anvil to an adjusted position with respect to said initial position; and (f) thereafter forming a second head on said rivet while retaining said parts support anvil in said adjusted position with respect to said rivet support anvil.
