Abstract

The invention discloses a blade processing system and method on an integral blisk. The clamping pin row of the blade clamping device in the system can realize self-adaptive clamping of the blade to be processed, and the blade clamping device can be used as a CNC machine tool. The auxiliary parts are placed in the tool magazine, and can be grasped, positioned, installed, removed and other operations by the spindle of the CNC machine tool. The servo motor can drive the blade clamping mechanism to rotate around the pivot, and then adjust the posture of the blade clamping mechanism. By controlling the supply of hydraulic oil in the blade clamping mechanism, the servo motor and the milling cutter, the machine tool realizes the finishing of the blade to be processed under the premise of ensuring the surface quality. A blade processing system and method on an integral blisk disclosed by the present invention can greatly reduce process preparation and operation time, remarkably improve the processing efficiency and processing cost of the integral blisk, and solve the high machining accuracy requirement of the aero-engine integral blisk , Processing difficult problems.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to a blade processing system and method on an integral blisk. Background technique [0002] The blisks and blades in the aero-engine adopt an integrated overall structure, which can reduce weight, improve mechanical properties, avoid airflow loss, improve aerodynamic efficiency, and increase thrust-to-weight ratio. As the new aero-engines widely adopt the integral structure of the blisk blades on the compressor rotor to form the blisk, the blisk is a key component widely used in aero-engines in recent years, and the processing volume of the parts on the blisk The proportion of the total processing volume of aero-engine parts is getting higher and higher. Since the blades of the overall blisk are densely arranged in a circular arrangement of multiple thin-walled special-shaped blades, the space between the blades is narrow, and the processing of the blades is prone to bl...
