Abstract

The invention discloses precision machining technological equipment for a blade of an aviation engine. The precision machining technological equipment comprises a positioning device, a clamping device and an auxiliary supporting device, wherein the positioning device, the clamping device and the auxiliary supporting device are fixed on a foundation table top, the positioning device is used for positioning of a curved surface of a blade body, the clamping device is used for clamping the blade body, the auxiliary supporting device is fixed outside the positioning device and the clamping device, a working head of the auxiliary supporting device directly contacts a tenon portion of the blade, and a master controller controls each hydraulic cylinder on a tool through a control loop. According to the precision machining technological equipment, the blade body provided with a thin wall and the curved surface is directly positioned and clamped for machining the tenon, and therefore continuous mechanical operation and machining can be achieved in production of the blade, and working efficiency and machining quality can be improved.

Description

technical field [0001] The invention relates to the technical field of processing aeroengine blades, in particular to precision processing equipment and a processing method for aeroengine blades. Background technique [0002] Compressor precision forging blades are the key components of aviation turbojet engines. At present, the main processing method for such blades in China is based on the processing method of casting low-melting point alloys on the blade body, that is, the precision forging and The rough material of the blade processed at the inlet and exhaust sides is clamped at six points, and the blade body is poured into a pouring block, and the complex point positioning of the blade body is converted into a regular surface positioning, and then the blade tenon is processed. However, this process has very obvious defects: long process chain, complicated production preparation, low work efficiency, the pouring and melting of low melting point alloys bring residue and c...
