The invention belongs to the technical field of precise optical working and relates to an electromagnetic coupling field-induced rheological polishing tool. Based on electro-rheological and magneto rheological effect, the invention utilizes ferro magnetic material as a polished shaft; when direct current low voltage is applied on an electromagnetic coil, the polished shaft is magnetized to form an electromagnet with the electromagnetic coil, and a vertically distributed magnetic field is produced near the tip of the polished shaft; when direct current high voltage is applied on a taper sleeve and two ends of the polished shaft, a horizontal electric field can be provided to obtain a cross field near a polishing head; when direct current high voltage is applied on a sheet metal and the polishing shaft, a vertical electric field can be obtained, and a parallel field is obtained near the polishing head. Electromagnetic rheological liquid generates rheological effect under the action of externally applied electric and magnetic fields; liquid particles are distributed in chain and intensively attached near the polishing head to form a small-size flexible liquid polishing head which forms relative shearing movement with workpiece surface under the drive of a motor, thus finishing the ultrasmooth polishing of minor-caliber aspherical mirrors, heteromorphic mirrors and free curved mirrors.
Description
technical field [0001] The invention relates to an electromagnetic coupling type field-induced rheological polishing tool, which belongs to the technical field of precision optical processing. Background technique [0002] With the development of optoelectronic information technology, micro-aspherical optical components have begun to be widely used in various modern optoelectronic products and image processing products, such as optical lenses of high-quality digital cameras, electron microscope lenses, camera viewfinders, and zoom systems. , Ophthalmoscope, endoscopic lens and so on in the medical industry. Compared with optical spherical elements, aspheric elements have irreplaceable advantages in improving image quality, simplifying system structure, reducing the number of components in the system and reducing the weight of the system. Traditional optical processing methods usually use asphalt as an abrasive, which is likely to cause subsurface damage and deterioration of...
