Abstract
The invention discloses a supercharging ultrasonic cavitation three-phase abrasive particle flow swirling polishing device. The device comprises a disc-shaped swirling polishing tool, a workpiece mounting platform and an ultrasonic bobble generator. A machined workpiece is mounted on the workpiece mounting platform. The disc-shaped swirling polishing tool is fixedly mounted over the machined workpiece. A knurl is arranged at the bottom of the disc-shaped swirling polishing tool, and a microspur finedraw is formed between the knurl and the surface of the machined workpiece. The ultrasonic bobble generator is arranged over the disc-shaped swirling polishing tool. Through the design of the top inlet angle and a conical inner cavity, the pressure and speed of an inner flow field are increased, and a gas-liquid-solid three-phase high-speed swirling flow field is formed by cavitation bubble generated by the ultrasonic bobble generator, so that the speed of abrasive particles in the gas-liquid-solid three-phase flow field is greatly increased, and the polishing efficiency of the workpiece is improved; by arranging the knurl and adjusting the distance of the microspur finedraw, an annular machining face generated by the swirling flow field is avoided, and large-area super-smooth uniformizing polishing is achieved.
