Abstract

The invention discloses an electric field electrorheological jet polishing device. The electrorheological jet polishing device comprises a work chamber, a rotary table, a machine tool, a jetting device, a filter, a stirring tank, a cooling device, a boosting device, flow guide pipes and an electrorheological polishing liquid. The machine tool does three-dimensional linear movement; the jetting device is fixed on a horizontal moving shaft driving device and faces the object carrying tabletop of the rotary table; the jetting device and the object carrying table of the rotary table are sealed by the work chamber; the filter is arranged between the work chamber and the stirring tank; the cooling device is arranged on the outer wall of the stirring tank; a boosting system is arranged between the jetting device and the stirring tank; and all parts of a system are connected through the flow guide pipes to form a liquid loop. When the electrorheological jet polishing device is in work, the electrorheological polishing liquid is boosted by the boosting device, input into the electrified jetting device, shaped by the jetting device and subjected to an electrorheological effect to form stable standard straight jets for polishing a workpiece; and waste liquid can be recycled for use after treatment. The electric field electrorheological jet polishing device combines an electrorheological polishing technology and a jet polishing technology and belongs to the domain of optical fine machining.

Description

technical field [0001] The invention relates to an optical precision polishing device, in particular to an electric field-induced rheological jet polishing device for processing optical elements, and belongs to the field of ultra-precision optical surface processing. Background technique [0002] With the continuous development of science and technology, people's requirements for optical components have gradually increased, so new polishing technologies have emerged as the times require. In the 1880s, the abrasive water jet polishing technology (Fluid Jet Polishing, referred to as FJP) developed rapidly; in the polishing process, the polishing liquid mixed with abrasive particles was accelerated by a high-pressure pump, and then ejected from the nozzle at a certain speed to impact the workpiece. Surface, due to the impact, the polishing liquid column spreads out in the radial direction, generating a tangential velocity relative to the workpiece surface, causing the abrasive ...
