Air bag polishing tool and system and method

Abstract

The invention discloses an air bag polishing tool and system and method. The air bag polishing tool comprises a motor, a speed reducer, a hollow rotating shaft and an air bag, wherein the motor, the speed reducer, the hollow rotating shaft and the air bag are sequentially connected. The hollow rotating shaft is provided with a hollow cavity, the two ends of the hollow cavity are communicated to the air bag and a ventilation guide pipe respectively, and an electrical proportional valve is arranged on the ventilation guide pipe. The air bag polishing tool further comprises a pressure intensity sensor for detecting the pressure intensity of air in the air bag and a pressure sensor for detecting the positive pressure of the tool. By means of the air bag polishing tool, based on the electrical proportional valve, the contact pressure and the contact pressure intensity of a polished surface can be controlled in real time, the air bag polishing tool can meet the requirements of different machined surfaces for different machining pressures, the machining accuracy can be improved, the polishing process can be simplified, the machining cost can be reduced, and the air bag polishing tool is simple in structure and easy to control.

Description

technical field [0001] The invention relates to an airbag polishing tool, in particular to a device capable of controlling the surface polishing contact pressure by controlling the air pressure in real time. Background technique [0002] In recent years, the optical curved surface and mold curved surface manufacturing industry has developed very rapidly and involves a wide range of areas. As the last process in the manufacture of optical curved surfaces and mold curved surfaces, polishing plays a vital role in the final quality and service life of curved surfaces. Balloon polishing is an emerging deterministic polishing process, especially suitable for polishing free-form surfaces. The so-called certainty means that the amount of material removal in the polishing process is controllable. Airbag polishing mainly enables the airbag to be in stable contact with various curved surfaces by controlling the pressure inside the airbag during polishing. When the residence time is co...

Problems solved by technology

Before the appearance of airbag polishing technology, the polishing tools generally used springs or other flexible materials to achieve flexible contact between the polishing tool and the polished surface, so that the contact force during the polishing process could be kept within a certain range as much as possible, but this Flexible contacts are generally difficult to achieve online control
