Problems solved by technology

[0003] The barrel finishing process technology has the characteristics of overall processing, comprehensive improvement of surface integrity characteristic parameters, and economical affordability. There are still problems such as poor processing effect on the blade root, easy to cause over-throwing of the intake and exhaust edges and blade deformation; even if the protection methods of surface coating resin and winding tape are used to protect the intake and exhaust edges, there are still low efficiency and poor repeatability The problem

Abstract

The invention discloses a blade surface roll-polishing finishing method adopting a distributed protection measure, and belongs to the technical field of machine part surface finishing. The method is characterized in that a blade and a blade basin protection device or blade back protection device are fixed to a fixture at a certain space angle, and the fixture is connected to a spindle; in the machining process, the spindle swings around the axis of the spindle, and the blade is machined in a work bin which contains machining media such as roll-polishing blocks and polishing liquid and rotates around the axis of the work bin. By means of the method, the blade finishing efficiency and uniformity can be effectively improved, the blade root machining effect can be improved, intake and exhaust sides can be prevented from being excessively polished, deformation of the blade in the machining process can be effectively reduced, and the blade can be protected.

Description

Technical field [0001] The invention relates to a blade surface rolling and finishing processing method adopting distributed protection measures, belonging to the technical field of surface finishing processing of mechanical parts, and specifically relates to a blade surface rolling finishing processing method adopting distributed protection measures. Background technique [0002] The engine is the heart part of the aircraft, and the blade is an important part of the engine. The blade profile is a free-form surface, and the processing quality of the blade has an important impact on the reliability of the aero-engine, and the surface quality of the blade directly affects the aerodynamic performance of the blade, and then affects the performance of the aero-engine. At present, there are manual polishing, abrasive belt polishing, abrasive flow polishing, shot peening, laser shock strengthening, etc. for blade finishing, but they all have certain limitations. For example, the consis...
