Description

Jet recovery adjusting device of magnetic liquid polishing device

Technical Field

The utility model relates to the technical field of optical element processing, in particular to a jet recovery adjusting device of a magnetic liquid polishing device.

Background

The magnetic liquid polishing technology is an important ultra-precision processing means in the field of optical element processing, and compared with the traditional optical polishing technology, the magnetic liquid polishing technology cannot generate subsurface damage on the basis of trimming the surface shape of a workpiece and reducing the surface roughness, and has high processing efficiency. The magnetic liquid is an intelligent material consisting of magnetic particles (iron powder), carrier liquid, polishing powder and other additive components. The magnetic particles in the magnetic liquid can generate obvious magneto-rheological effect under the action of the magnetic field, and the liquid and the solid or semisolid can be rapidly and reversibly switched according to the size of the magnetic field inside the polishing wheel. When the magnetic liquid is conveyed to the upper end of the polishing wheel by the nozzle and rotates to a polishing area along with the upper end of the polishing wheel, the magnetic liquid is converted into a fluid with viscoplasticity under the action of a magnetic field of a magnet arranged in the polishing wheel, and a flexible polishing ribbon is formed to be in contact with the surface of a part to be processed, so that the surface material of the workpiece is removed. After polishing, the flexible ribbon flows out of the processing area along with the polishing wheel, the magnetic field is greatly weakened, and the magnetic liquid is switched into a liquid state again and recovered by the recoverer.

In the field of optical processing, the demands for the surface quality of an optical lens are extremely high, and therefore, high demands are also made on the rotational accuracy of a polishing apparatus, the shape of a polishing ribbon, and the recovery rate of a recovery apparatus. The rotation precision of the polishing device is mainly determined by the machining precision of the polishing wheel, the precision of the rotary bearing and the like, and generally speaking, the rotation precision of the current polishing wheel can reach a better level, and the rotation precision of the polishing wheel on the whole can basically meet the use requirement of the polishing device.

The polishing ribbon is greatly influenced by the flow stability of the circulating system and the position of the jet pipe, a certain lifting space also exists, and particularly the shape of the polishing ribbon is directly influenced by the position of the jet pipe relative to the polishing wheel, so that the quality of the processed surface is influenced.

If the recovery device does not completely recover the magnetic liquid, the thickness of the magnetic liquid ribbon above the polishing wheel fluctuates, and the polishing quality of the surface of the optical lens is further influenced. The position of the recovery device relative to the polishing wheel has a great influence on the recovery rate of the magnetic liquid, the recovery device is generally required to be right above the polishing wheel ribbon, and the gap between the recovery device and the polishing wheel is strict, so that the position adjustment of the recovery device relative to the polishing wheel is more critical during assembly.

Because the magnetic liquid in the magnetic liquid circulating system is easy to harden, the components through which the magnetic liquid in the circulating system flows need to be periodically disassembled, assembled and cleaned, and therefore the convenience of disassembling, assembling and debugging of each component directly influences the working efficiency. Particularly, the requirements on the positions of the injection pipe and the recoverer relative to the polishing wheel are strict, so the simplicity of assembling, disassembling and adjusting the injection pipe and the recoverer is more important.

The prior magnetic liquid polishing device has the following defects in the regulation of an injection pipe and a recoverer:

1. the adjusting device of the injection pipe and the recoverer has more adjusting freedom, and needs a plurality of persons to be matched simultaneously when adjusting due to the inherent defects of the structure, so that the adjustment is complex;

2. the injection pipe is not provided with a positioning device, and the position of the injection pipe needs to be readjusted when the injection pipe is reassembled after being cleaned every time, so that the efficiency is low;

3. the prior recoverer adjusting mechanism is difficult to adjust the recoverer to the optimal position, and easily causes the problems of side leakage of magnetorheological fluid, low recovery efficiency and the like.
