Integral leaf disc machining system and method

Abstract

The invention discloses an integral leaf disc machining system and method, and aims to solve the problems such as low efficiency, unstable precision, great labor intensity and great dust harm due to the fact that an existing aero-engine leaf disc must adopt an artificial grinding and polishing process after being subjected to milling or electrolytic machining. The system comprises an industrial robot, a grinding device, a leaf disc, a rotary table and a control cabinet. An integral leaf disc machining path is planned and machining program is transmitted into a controller of the industrial robot; the industrial robot is started to drive an abrasive belt grinding device to enter an machining area; the industrial robot controls the grinding device to machine a target blade on the leaf disc according to the pre-planned grinding path; and the rotary table drives the leaf disc to rotate by certain angle, and the grinding and machining of each blade molded surface of the whole leaf disc are completed by repeating the process. The integral leaf disc machining system is delicate in structure, is high in grinding and machining efficiency, is flexible in working mode, is low in machining cost, eliminates potential hazards of artificial grinding operation, and has a relatively high practical value and a relatively high popularization value.

Description

technical field [0001] The invention belongs to the technical field of aviation manufacturing, and relates to the smoothing and precision machining of an integral blisk, in particular to an efficient grinding and processing system of an aero-engine integral blisk and a realization method thereof. Background technique [0002] The blisk is the latest structure and aerodynamic layout adopted by Western developed countries in the design of aero-engines, and it is the core component for high-performance aero-engines to achieve structural innovation and technological leap. Compared with the traditional assembly structure, the integral blisk designs the blade and the disc into an integral structure, which saves the tenon, tenon and locking device used in the traditional connection, reduces the structural weight and the number of parts, and avoids tenon airflow The loss greatly simplifies the engine structure. [0003] The overall blisk is mainly roughed by integral milling or ele...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the high value and high-precision processing requirements of the blade disc, the manual finishing operation needs to be extremely careful, the operation efficiency is extremely low, the labor intensity is also high, and it is difficult to ensure the stability of the blade grinding and polishing surface quality;

[0007] 2. Grinding and polishing processing is carried out in the form of special CNC grinding machines. The equipment procurement costs are expensive, and the maintenance and use costs are also high, which brings great risks and operating costs to relevant aviation development companies.
