Abstract
A method and apparatus for forming rivet joints that allow pivotal motion of the parts interconnected by such joints with a desired amount of clearance. Parts to be riveted together are aligned with each other and held in place on a parts support anvil, and a rivet is placed into aligned holes. A rivet support anvil is positioned against the head of the rivet to establish an initial condition. The rivet support is adjusted a required amount with respect to the parts support anvil prior to formation of the second head on the opposite end of the rivet. The rivet is allowed to move a controlled amount prior to formation of the second head, to provide the desired amount of clearance.
Claims1
A method of riveting a plurality of parts together to form an assembly with a predetermined clearance or interference between a rivet and the parts interconnected by the rivet, comprising:
- (a) urging together a parts clamp and a parts support anvil against opposite sides of a plurality of parts to be riveted together;
- (b) urging a rivet anvil against a first head of a rivet, thereby urging the rivet into a first position with respect to the parts to be riveted together and establishing an initial condition;
- (c) thereafter adjusting said rivet anvil with respect to said parts anvil, thereby creating an adjusted condition;
- and
- (d) thereafter forming a second head on said rivet while retaining said parts support anvil and said rivet anvil in said adjusted condition.
