Abstract

The invention belongs to the field of ultra-precise optical surface machining tools, and relates to an electro-rheological pendulum shaft cylindrical polishing device. The polishing device comprises a motor, a bracket seat, a connecting rod, a rotating shaft, a base, a circular electric brush, anode and cathode polishing devices and a hard insulating material, wherein the motor is arranged on thebracket seat; one end of the rotating shaft is connected with a rotating shaft of the motor through a shaft coupling, while the other end is fixed with the cathode polishing device; during polishing,the rotating shaft and a workpiece shaft form a certain angle; the anode and cathode polishing devices and the hard insulating material are fixed together to form an integrated electrode polishing head; a bracket and the base are fixed through the connecting rod; an electric brush sleeve is fixed on the base by bolts; the circular electric brush is placed in a groove of the electric brush sleeve and is tightly contacted with the upper end of the anode polishing device; and during working, the electro-rheological fluid is gathered at the edge of the integrated electrode polishing head to implement polishing when the electro-rheological fluid and a workpiece are contacted and produce relative motion. The anode and the cathode of the polishing device can rotate integrally, and the rotating shaft can swing randomly, so the polishing device is applicable to definiteness machining for complex optical surfaces.

Description

technical field [0001] The invention relates to a polishing device, in particular to an electrorheological pendulum shaft cylindrical polishing device, which belongs to the field of ultra-precision optical surface processing tools. Background technique [0002] With the rapid development of the optoelectronic industry, the quality requirements for the optical components used are getting higher and higher, which promotes the research on optical component processing devices. The traditional optical polishing method relies entirely on manual asphalt polishing based on cerium oxide polishing fluid. This polishing process is non-repeatable, non-deterministic, and takes a long time and is uncertain. In the new century, computer-controlled optical surface shaping (CCOS), stressed lap polishing (Stressed Lap Polishing), ion beam polishing (Ion Polishing), and magnetorheological polishing (MRF) technologies have developed rapidly. Computer-controlled optical surface forming technolo...
