Embodiment Construction

[0009] The structure of the polishing device of the present invention is as figure 1 As shown, it includes a vibrator 1, a blade 2 is set on the vibrator 1, and a magnetic field generator 3 is set on both sides of the blade 2. The vibration direction of the blade 2 is perpendicular to the direction of the magnetic force line. When the magnetic abrasive grain 4 is not applied with a magnetic field, its polishing process The effect is the same as that of ordinary vibrating finishing; under the condition of applying a magnetic field, the magnetic abrasive particles 4 can be condensed into a whole, and the magnetic abrasive particles 4 can fit well with the corrugated shape produced by the milling tool marks on the surface of the blade, which can be very complete Copy the waviness of the surface of the blade, so that an integral polishing medium can be formed around the curved surface of the blade. When the blade reciprocates up and down under the action of the vibration source, th...

Abstract

The invention discloses an automatic polishing method and device for a finish-milling hook face. A magnetic grinding material is adopted, and when no magnetic field is applied to the grinding material, the polishing process effect of the grinding material is the same as that of a common vibration burnisher; under the condition that the magnetic field is applied, the magnetic grinding material can condense into a whole; the grinding material can be well matched with the shape of ripples generated by milling tool marks on the surface of a blade, the waviness of the surface of the blade can be completely copied, and therefore a whole polishing medium can be formed on the periphery of the hook face of the blade; and when the blade does up-and-down reciprocating motion under the effect of a vibration source, the overall polishing medium can effectively remove residues of the milling tool marks, namely materials at peaks of the ripples on the surface of the blade. The automatic polishing method and device have the beneficial effects that the effect of free vibration burnishing can be achieved, the aim of selectively removing the tool marks can be achieved, and about 70% of working amount of manual polishing for tool mark removing can be replaced.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a blade polishing method and device. Background technique [0002] Fine polishing of the blade surface is one of the core technologies in the manufacture of blades without margin. At present, the polishing methods in the world are mainly manual polishing and automatic polishing by numerical control equipment. The characteristics of these two methods are that special equipment and polishing abrasives are required. Manual polishing quality control is difficult. The cost of automatic polishing equipment is high and there are polishing blind spots. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a simple polishing method, which has good versatility, is suitable for polishing most blades and can realize fine milling surface finish polishing. The specific technical scheme is as follows: [0...
