The invention discloses an acoustic-liquid-solid-coupling two-dimensional ultrasonic deep-rolling machining device. The acoustic-liquid-solid-coupling two-dimensional ultrasonic deep-rolling machiningdevice at least comprises an acoustic element, a hydraulic assembly and a tool assembly, wherein the tool assembly comprises a base which is equipped with a base groove and a ball bearing which can be arranged in the base groove, can be rolled and can impact the surface of a workpiece; the acoustic element comprises an amplitude transforming rod, an ultrasonic energy converter and an ultrasonic generator which is connected with the ultrasonic energy converter through a wire; the ultrasonic energy converter is mounted on the amplitude transforming rod; and the hydraulic assembly comprises a liquid supply pipeline which is arranged on the base, and the liquid supply pipeline communicates with the base groove. According to the acoustic-liquid-solid-coupling two-dimensional ultrasonic deep-rolling processing device disclosed by the invention, the advantages of deep rolling machining and two-dimensional ultrasonic machining are integrated, and ultrasonic impact, ultrasonic cavitation and jet flow polishing are produced by utilizing a coupling effect on a two-dimensional ultrasonic field and a flow field; and the ball bearing acts upon workpieces, excellent and effective surface enhancement of low-rigidity metal workpieces can be realized, and the service life of the ball bearing is prolonged.
Description
technical field [0001] The invention relates to the technical field of surface strengthening of metal parts, in particular to an acoustic-liquid-solid coupling two-dimensional ultrasonic deep rolling processing device. Background technique [0002] Metal parts are widely used in various mechanical equipment. Since metal parts are often damaged due to surface wear, corrosion and fatigue, it is usually necessary to use surface strengthening techniques such as rolling and shot peening to improve the processing quality and surface mechanical properties of metal parts and improve wear resistance. Corrosion and fatigue resistance to extend the life of metal parts. [0003] Ultrasonic deep rolling is formed by the combination of rolling and ultrasonic machining. It is a kind of surface strengthening treatment technology. It was developed by Bozdana et al. in 2005 on the basis of deep rolling. They use ultra-high pressure fluid to make the ball and the workpiece tightly Contact, t...
