Restraining abrasive particle flow polishing device of hard and brittle material complex curve part

Abstract

Provided is a restraining abrasive particle flow polishing device of a hard and brittle material complex curve part. The restraining abrasive particle flow polishing device of the hard and brittle material complex curve part comprises a polishing tool head, a spring, a tightly-driven screw, a fixing seat, a recovery base and a polishing robot, wherein the polishing tool head is a tool head which is manufactured by insensitive elastic materials to abrasive particle abrasion, the tightly-driven screw is formed in a central hole of the fixing seat in a sleeved mode, the spring is arranged outside the tightly-driven screw in a sleeved mode, the other end of the tightly-driven screw is connected with the polishing tool head and tightly compresses the spring, a workpiece is fixed on the recovery base, the fixing seat is fixed with the tail end of the polishing robot, a counter bore is formed in the upper position of the central hole of the fixing seat, and a gap is arranged between the top end of the tightly-driven screw and the tail end of the polishing robot; the center of the recovery base is a boss, abrasive particle flow recovery grooves are formed around the boss, a circle abrasive particle flow baffle is arranged on the periphery of the recovery groove, the abrasive particle flow baffle is higher than the upper surface of the workpiece, and an abrasive particle flow recovery outlet is formed in the recovery grooves. The restraining abrasive particle flow polishing device of the hard and brittle material complex curve part has the advantages of being high in polishing precision and material removal rate, small in manufacturing damage of the surface of the workpiece and low in cost.

Description

technical field

[0001] The present invention relates to a polishing device. Background technique

[0002] Hard and brittle materials such as optical glass, optical crystal, and engineering ceramics have excellent mechanical properties such as high hardness, good wear resistance and corrosion resistance, and unique optical properties. The requirements for processing accuracy and surface quality are becoming more and more stringent. Hard and brittle materials The ultra-precision machining technology of parts has become one of the urgent needs and the most challenging processing technology fields.

[0003] Traditional mechanical polishing methods have obvious defects in controllable material removal, surface damage, and processing efficiency. It is difficult to meet the processing requirements of high-precision ultra-smooth and low-damage optical surfaces, and is no longer suitable for ultra-precision processing of such optical components.
