Device for performing precise supercooled polishing to tiny spheres

Abstract

A device for performing precise supercooled polishing to tiny spheres relates to a polishing device and is provided with an automatic feeding mechanism, a polishing mechanism and a material recovery mechanism, wherein the automatic feeding mechanism is provided with a raw material chest, a rotary table, a base and a conveying pipe; the polishing mechanism is provided with a lifting and clamping device, an upper pressure intensity maintaining cover plate, a lower pressure intensity maintaining cover plate, a pressure sensor, an upper concave polishing cushion, a lower concave polishing cushion, an ultrasonic vibration generating device and a rotational device; and the material recovery mechanism is provided with a slope and a material recovery chest connected with each other. When the device is processed, complicated operations are avoided, and the only requirements are to place the processed sphere into the raw material chest and set relevant parameters and procedures, so that automatic production is realized and feeding, and polishing and material recovery are all automatically carried out according to preset parameters and procedures; and through the adoption of the ultrasonic vibration polishing method, the commonly existing defects in the traditional mechanical polishing can be solved, such as damaged polishing cushions, large surface stress after polishing, lots of foreign objects, lower corrosion resistance, easily-caused local pitting, etc.

Description

technical field [0001] The invention relates to a polishing processing equipment, in particular to a processing device for performing precise ultra-cold lapping and polishing on tiny spheres by using an ultrasonic vibration polishing method. Background technique [0002] Polishing technology is an indispensable pretreatment technology in the surface treatment process of metal and non-metal materials. It can not only make the surface smooth and bright, but also make the surface clean and free of foreign matter. Therefore, polishing technology is a more important pretreatment technology than degreasing and pickling. Metal polishing has a history of more than 100 years. It was born with the industrial revolution and developed with the development of the technological revolution. It has been widely used in industry. For example, polished stainless steel plates and stainless steel products have been widely used in automobiles, cooking utensils, bath utensils, trains, elevators,...

AI Technical Summary

Problems solved by technology

In the early days, mechanical polishing was mostly used, but high pressure was required during mechanical polishing. Due to the poor thermal conductivity of stainless steel, polishing under high pressure can easily cause overheating, which often leads to damage to the polishing pad, and the surface stress after mechanical polishing is large and there are many foreign objects. , Corrosion resistance decreases, so it is easy to cause local pitting corrosion when used
