Abstract

The invention provides an online homogenization device for magnetorheological polishing fluid. The magnetorheological polishing liquid in the device of the present invention is stored in the liquid storage tank, the transmission pump body is immersed in the polishing liquid in the liquid storage tank, the forward paddle is connected by screws and installed and fixed on the bottom of the transmission pump body, and the reverse paddle passes through the The screw is connected and installed in the middle of the transfer pump. The homogenization driver drives the homogenization motor and drives the liquid storage tank to rotate forward and reverse at low speed, so as to realize the forward and reverse movement of the stirring blade relative to the tank and stir and homogenize the magnetorheological polishing liquid. The invention can realize the homogenization of each component of the magnetorheological polishing liquid, solve the problem of long-term working settlement of the magnetorheological polishing liquid, and is suitable for on-line homogenization of the magnetorheological polishing liquid in a wide range of high and low viscosity, and improves the magnetorheological polishing The stability control of liquid components realizes the high-precision and high-reliability polishing of optical components by magnetorheological polishing liquid.

Description

technical field [0001] The invention belongs to the field of polishing processing of optical elements, and in particular relates to an online homogenizing device for magnetorheological polishing fluid. It is suitable for online homogenization of magnetorheological polishing fluid with high and low viscosity in a wide range, improves the stability control of magnetorheological polishing fluid components, and realizes high-precision and high-reliability polishing of optical components by magnetorheological polishing fluid. Background technique [0002] Magneto-rheological polishing technology is known as a revolutionary technology in the optical manufacturing industry. It uses the controllable rheology of magnetorheological polishing fluid to achieve precise and deterministic removal of workpiece materials, and can obtain high-precision models below tens of nanometers with high efficiency. Surface, nano-scale surface quality and almost no sub-surface defects, which can well me...
