The invention relates to a blade type rapid detection device and method after blisk electrolysis and rough machining. The device comprises a blisk positioning tool, a detection tool and a detection sample plate. The blisk positioning tool comprises a base plate, a central column and a positioning element; a plurality of base plate positioning holes related to blades of a blisk are formed in the base plate in a circumferential direction; blisk positioning holes matched with the base plate positioning holes are formed in the blisk; the blisk and the base plate are mounted coaxially through the central column; the positioning element is used for penetrating the blisk positioning hole and the base plate positioning hole to relatively position the blisk and the base plate; the detection tool comprises a mounting base, a sliding guide groove and an adjusting block; the base is detachably mounted on a peripheral side wall of the base plate; the sliding guide groove is in sliding connection with the base; the adjusting block is arranged on the sliding guide groove; the detection sample plate is mounted in the sliding guide groove, adjusts a mounting gap by the adjusting block, and is usedfor detecting a blade type gap after electrolysis and rough machining; and the detection sample plate includes a blade basin detection sample plate and a blade back detection sample plate.
Description
Technical field [0001] The present invention relates to an electrolytic processing technology, and more particularly relates to the airfoil and a method for rapid detection apparatus after a blisk roughing electrolysis. Background technique [0002] At present, the overall design concept has been widely used in aviation manufacturing technology, in particular for the manufacture of aircraft engines, which will improve the performance and life of the engine. E.g. blisk, the blades and the disk is designed as a whole, eliminating the tenon, and the locking tongue and groove means to avoid the loss of air flow tenon, reducing the number of parts and the weight of the structure, greatly simplifying the structure of the engine, reduce weight ; improved engine efficiency, thrust-weight ratio and reliability to further enhance the rapid development of manufacturing technology. [0003] Electrochemical machining of blisks divided into roughing and precision molding process. Electrolytic ...
