Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing three-phase abrasive particle flow ultrasonic processing system has a low degree of automation, cannot uniformly ensure the uniformity of the surface of the processed workpiece, the efficiency of processing the workpiece is low, the processing of the workpiece is not progressive, and it cannot be well adapted to the processing of different workpieces. In order to meet the demand, an automatic, gradual and efficient three-phase abrasive flow ultrasonic processing method and device are proposed. In the method, based on the division of the surface area of ​​the workpiece, a variety of powers and multiple distances are used in each part of the area. processing methods

Abstract

The invention discloses an efficient gradualness polishing method and device based on a gas-liquid-solid three-phase abrasive particle flow. A region partition is carried out on the surface of a workpiece, and ultrasonic bubble generators with different power and different distance are adopted to carry out an integral gradualness processing method. The device comprises a control system, a cavity body rack, a stepping motor, a driving core shaft, a driving chain wheel, a driven gear, a chain, a cross-shaped supporting frame, a four-location rotary device, a rising and falling mechanism and the ultrasonic bubble generators; by conducting processing by four locations simultaneously, the processing efficiency is greatly improved, and suitable processing methods can be assigned aiming at different processing workpieces and mainly aims at arranging multiple height and multiple power; the gradualness is obtained by the processing process, and the processing quality and efficiency are guaranteed; rotation of the four locations drives installing platforms to conduct autogiration, and different-angle processing can be carried out on the workpieces; the whole processing process is automatically controlled by a system, and no workers need to watch over.

Description

technical field [0001] The invention relates to the technical field of ultra-smooth surface polishing processing equipment, and more specifically, to a high-efficiency progressive polishing method and device based on gas-liquid-solid three-phase abrasive particle flow. Background technique [0002] Gas-liquid-solid three-phase abrasive flow processing refers to a new method of further driving abrasive flow processing with the help of gas phase. It is mainly used in the processing of K9 optical glass and single crystal silicon that require extremely low surface roughness (<1nm RMS). Abrasive flow processing mainly refers to the processing of the surface of the workpiece by the high-speed flow of the abrasive flow carrying fine abrasive particles without relying on the processing tool to directly contact the surface of the workpiece. This method is also called fluid polishing. [0003] From the perspective of the special requirements of ultra-smooth surface processing, flu...
