Finishing machining system based on flexible controlled air pressure grinding wheel

Abstract

The invention relates to a finishing machining system based on a flexible controlled air pressure grinding wheel, which comprises a flexible controlled air pressure grinding wheel finishing tool, wherein the flexible controlled air pressure grinding wheel finishing tool is arranged above a working table and contacted with a machining workpiece of the working table; the flexible controlled air pressure grinding wheel finishing tool is connected with a driving device, a rotating control system for controlling the flexible controlled air pressure grinding wheel to rotate, an air pressure control system for providing air pressure, and a robot for controlling the walking route, retention time and deflection gestures of the flexible controlled air pressure grinding wheel; and the flexible controlled air pressure grinding wheel consists of an annular flexible air pressure grinding wheel and a grinding wheel supporting body, the annular flexible air pressure grinding wheel has an annular hollow structure and consists of an elastic support and a grinding and polishing layer connected on the elastic support, the annular flexible air pressure grinding wheel is arranged on the grinding wheel supporting body and form an inner cavity with the grinding wheel supporting body, and the inner cavity is communicated with the air pressure control system. The finishing machining system has the advantages of high material removal rate and high finishing machining quality.

Description

technical field [0001] The invention relates to a finishing system based on a flexible and controllable air pressure grinding wheel, in particular to a finishing system combined with robot-assisted polishing technology, which is suitable for high-quality surface requirements for free-form surface polishing, especially for high hardness and high resistance after laser strengthening. Abrasive surface, with very good processing quality and efficiency. Background technique [0002] Finishing refers to the process of not cutting or cutting out an extremely thin metal layer from the workpiece to be processed after finishing to improve the surface roughness of the workpiece or strengthen its surface. The commonly used methods include polishing and grinding. Due to the increasingly wide application of free-form surfaces in industry, and the constant changes and complexity, the difficulty of finishing processing also increases. [0003] At present, in our country, the polishing is m...
