Abstract

The invention discloses a polishing tool, belonging to the field of precision optical surface processing. A rotary type magnetic jet polishing device comprises a bracket, a sleeve, a shell, a motor, a motor frame, an adaptor, a rotating shaft, a bearing component, a sealing component, a sprayer, a sprayer nut, a coil rack, a coil, a magnetic isolation component and the like, wherein the sleeve is fixed in the bracket; the rotating shaft is arranged in the sleeve through the bearing component in a rotating manner and is sealed with the sleeve through the sealing component in a rotating manner; the rotating shaft is fixed to a rotor of the motor through the adaptor; the motor is fixed on the sleeve through the motor frame; the sprayer is fixed at the lower end of the rotating shaft through the sprayer nut; a magnetic isolation cavity and a cavity cover work together to clamp the coil and then the magnetic isolation cavity, the cavity cover and the coil are all together fixed at the lower end of the sleeve through the coil bracket; and the shell is fixed to the sleeve. During working, the motor drives the sprayer to rotate, liquid is sprayed out of the sprayer through an inner passage of equipment and then polishes a workpiece after passing through a magnetic field produced by the electrified coil. A polished spot with an area being larger than that of a spraying hole is obtained by rotary spraying of the specially-shaped sprayer and the magnetic jet flow processing efficiency is effectively improved.

Description

technical field [0001] The invention relates to a magnetic jet polishing tool head, in particular to a special-shaped nozzle rotating magnetic jet polishing device for processing optical elements, and belongs to the field of ultra-precision optical surface processing. Background technique [0002] With the improvement of the shape and quality requirements of optical parts, the traditional grinding and polishing has been greatly restricted in practical application, thus driving various new polishing technologies to flourish. In the 1980s, the emergence of computer control optical surfacing technology (computer control optical surfacing) effectively improved the efficiency of optical surface finishing, but due to the wear and deformation of the grinding head, high-frequency errors and mechanical interference, etc., it is limited It is the category of optical parts processing. In the late 1990s, magnetorheological polishing technology (magnetorheological finishing) was applied...
