Laser and magnetorheological fluid coupling polishing device

Abstract

The invention discloses a laser and magnetorheological fluid coupling polishing device. The laser and magnetorheological fluid coupling polishing device comprises a laser transmitter, a laser guide rail, an electromagnet, a polishing wheel, a rotatable support, a laser guide rail sliding block, a bottom seat, a workpiece feeding device and a magnetorheological fluid circulation device. The laser and magnetorheological fluid coupling polishing device adopts coupling effect of magnetorheological fluid and laser for polishing, is high in processing efficiency and processing accuracy, and good inprocessing quality, and easily controls processing conditions. The magnetorheological fluid is changed into solid-like substances under the action of a magnetic field, and the solid-like substances are equivalent to a plurality of flexible grinding heads, and then the flexible grinding heads perform opposite movement relatively to a workpiece under drive of the polishing wheel, and thereby achievegrinding and polishing effects. The laser can transmit heat to the surface of the workpiece through heat conduction, and therefore shear resistance on the surface of the workpiece is reduced, the surface of the workpiece is softened, and polishing efficiency and polishing quality are improved. The workpiece feeding device achieves precise processing for each position on a part in irregular shape.The magnetorheological fluid circulation device achieves cyclic utilization for the magnetorheological fluid. The laser and magnetorheological fluid coupling polishing device is ingenious in design and low in manufacture cost.

Description

technical field [0001] The invention relates to the field of ultra-precision machining, in particular to a laser and magnetorheological fluid coupling polishing device. Background technique [0002] With the development of science and technology, people have higher and higher requirements for precision instruments and measurement accuracy, especially in the field of optics. Due to the current pursuit of optical systems with high resolution and large field of view, the design of aspheric mirrors is generally used. However, affected by many factors such as the size of polishing tools, the ultra-precision processing technology of small curvature radius concave aspheric and free-form surface components is The huge problem facing optical processing at present. [0003] The current polishing technology is roughly divided into direct contact polishing, interface reaction polishing (quasi-contact polishing) and non-contact polishing. Direct contact polishing is the direct contact ...

Problems solved by technology

The advantage of this kind of polishing device is that it is simple in structure, easy to operate, and easy to process narrow and long working surfaces; the disadvantage is that the processing efficiency is low, the surface roughness is not up to standard, the shape of the processed workpiece is limited, it is impossible to polish each point, and the magnetorheological fluid cannot be recycled.
