Abstract

The invention relates to an abrasive band magnetorheological double curvature controllable composite finishing tool, and belongs to the technical field of precision optical machining. A macro curvature adjustment mechanism, a motor, a driving wheel and a tensioning wheel are fixed to a rack, wherein an output shaft of the motor is connected with the driving wheel, the driving wheel, the tensioning wheel and the macro curvature adjustment mechanism are wound by an abrasive band, and a magnetorheological fluid supply and recovery system is arranged below the abrasive band. The abrasive band magnetorheological double curvature controllable composite finishing tool has the following advantages: a microscope self-adapting flexible deformation advantage of magnetorheological finishing can be maintained, a macro active curvature controllable technical advantage of stress disc machining can be exerted, the problem that wide-range complete fitting machining can not be realized in the prior art can be solved, and the machining efficiency and the machining quality of a large workpiece are improved.

Description

technical field [0001] The invention belongs to the technical field of precision optical processing, and in particular relates to an abrasive belt and magnetorheological double curvature controllable composite finishing tool system. Background technique [0002] Complex optical curved surfaces are the core components of high-resolution optical systems. They are characterized by inconsistencies in the curvature of the surface and a large rate of curvature change. At the same time, the requirements for the accuracy of the surface shape are extremely high. The magnetorheological polishing method has both surface shape accuracy and surface roughness nano-manufacturing capabilities, and in a certain sense can meet the extremely demanding processing requirements of high-end optical components for surface shape accuracy and surface roughness. Patent CN103921176A discloses a magneto-rheological polishing device, which uses a large-diameter polishing wheel for polishing, which improv...
