Abstract

The invention discloses a finishing machining device of complex surfaces and a technique thereof, belongs to the field of special processing technology and is characterized in that high-intensity supersonic vibration produced by direct shock excitation to workpieces by an ultrasonic horn acts with the liquid and solid two-phase flow forced on surfaces of complex workpieces, thus producing the impact of workpiece surfaces and grinding particles and liquid cavitation to cause the impact to workpiece surfaces by the grinding particles, and the finishing machining of complex workpiece surfaces isrealized; and particularly, inner concave surfaces with complex channels also have the high-intensity supersonic vibration and the all-pervasive characteristic of the liquid and solid two-phase flow.The device and the technique have the advantages of realizing the finishing machining of complex inner and outer surfaces and also solving the problem that inner concave surfaces and dead corners cannot be finished and machined. The technology can fully and effectively finish and process inner surfaces, and effectively reduce the surface roughness value of parts, thus greatly improving the surface matching quality, surface wear resistance, surface air tightness, cleanliness and service life of parts.
