APPARATUS FOR MOUNTING AND SECURING PARTS (VARIANTS) Russian patent published in 2004 - IPC

FIELD: manufacture of aircraft engines, possibly mounting and securing parts such as blades of compressors of gas-turbine engines.

SUBSTANCE: in one variant apparatus includes two mounting centers arranged on the same axis with possibility of motion along it and one closing center whose axis is normal relative axis of mounting centers. Mounting centers are arranged at both sides from axis of closing center. Indexing disc is mounted in the same axis as closing center. Indexing disc has central groove for placing part and basic surface parallel relative to disc axis. Spacing between basic surface and disc axis is equal to that between part axis and its basic end. Mounting centers are arranged in walls of said groove. In second variant of invention apparatus includes two mounting centers and one closing center mounted with possibility of motion along mutually parallel axes. Mounting centers are arranged at both sides from axis of closing center. Indexing disc of apparatus is arranged in the same axis as closing center and it is designed for placing in it mounting centers. Spacing between disc axis and axis of one of mounting centers is equal to spacing from part axis until its one basic opening. Distance between axes of mounting centers is equal to spacing between axes of basic openings of part. Invention provides coincidence of part axis with axis of closing basic center of apparatus at placing each new part and at placing the same part in opposite sides.

EFFECT: enhanced accuracy of mounting parts due to improved design of apparatus.
