Device for realizing rotary fluid supply and recycle during revolving/rotating type magnetorheological polishing

Abstract

The invention relates to a device for realizing rotary fluid supply and recycle during revolving/rotating type magnetorheological polishing, which comprises a shell, a revolving base, a bearing block, a rotating shaft, a polishing wheel, a circulating system and other necessary auxiliary devices, and is characterized in that the circulating system comprises a first fluid injection channel, a second fluid injection channel, a first fluid extraction channel, a second fluid extraction channel, a fluid injection annular groove, a fluid extraction annular groove and a sealing ring. Magnetorheological polishing fluid in a fluid storage tank flows into the fluid injection annular groove and the second fluid injection channel through the first fluid injection channel on the shell and is added onto the polishing wheel through a fluid injection nozzle. The magnetorheological polishing fluid recycled by a collector flows into the second fluid extraction channel on the shell through the first fluid extraction channel and the fluid extraction annular groove and finally returns to the fluid storage tank. The problem of settlement and unsmooth operation of the magnetorheological polishing fluid during circulation in the existing revolving/rotating type magnetorheological polishing technology can be solved, and the problem that the pipeline cannot be cleaned automatically via the operation of a pump also can be solved.

Description

technical field [0001] The patent belongs to the technical field of optical ultra-precision machining, and in particular relates to a device for realizing rotary liquid supply and recovery in the magnetic rheological polishing of orbital rotation. Background technique [0002] Magnetorheological polishing of optical parts is an emerging deterministic polishing technology. Magnetorheological fluid is a smart material composed of magnetic particles, carrier fluid and other added components. Since the magnetic materials in it will be rearranged in the magnetic field, the magnetorheological fluid will undergo rheology within milliseconds under the action of the magnetic field, changing from a liquid state to a solid state. The rheological magnetorheological fluid has a higher shear yield strength. Adding polishing abrasives to the magnetorheological fluid can form a magnetorheological polishing fluid. Under the action of a magnetic field, the magnetorheological polishing fluid...
