Problems solved by technology

[0003] At present, in the airbag polishing process, the spherical airbag processing is mostly used (Chinese patent CN102825543A). When the spherical airbag is processed, because only one end is connected, the structure of the machine tool is similar to that of the mechanical arm. Although the degree of freedom is high, its dynamic balance is relatively low. Difference

Abstract

The invention discloses a circular arc radius adjustable disc type air bag polishing head, and relates to air bag polishing tools. The disc type air bag polishing head is provided with adjusting screw rods, an annular air bag support, an annular elastic outer layer, an annular elastic inner layer, an elastic inner layer fixing sleeve, adjusting flanges, an air bag support fixing sleeve and a polishing material layer. The adjusting screw rods are provided with adjusting threaded sleeves and spindle connecting rods. The annular elastic inner layer is bonded with the elastic inner layer fixing sleeve, the elastic inner layer fixing sleeve is provided with a supporting plate, and the supporting plate is provided with a slotted hole. The elastic inner layer fixing sleeve and the annular elastic outer layer are integrally placed into a clamping groove of the adjusting flanges. The air bag support fixing sleeve enables the annular air bag support to be fixed on the adjusting flanges and to be closely matched with the adjusting flanges, and the annular elastic outer layer is directly arranged on the annular air bag support in an injection molding mode. The adjusting threaded sleeves are screwed into the two screw rods respectively, the spindle connecting rods are placed into the adjusting threaded sleeves, and the polishing material layer is bonded on the surface of the annular elastic outer layer. The air bag circular arc radius is adjustable, dynamic balance performance is good, and positioning accuracy and machining accuracy are improved obviously.

Description

technical field [0001] The invention relates to an airbag polishing tool, in particular to a disc type airbag polishing head with adjustable arc radius for polishing plane, spherical and aspherical optical crystals. Background technique [0002] Disc airbag polishing is a novel polishing method, which is very suitable for polishing aspheric optical lenses. At present, this technology is in the research and development stage at home and abroad. Compared with traditional polishing tools, the disc-shaped airbag polishing technology can not only ensure good local contact between the polishing head and the surface of the polished workpiece, but also control the polishing efficiency and the surface quality of the polished workpiece by adjusting the pressure. Therefore, it is an aspheric polishing method with great development potential. [0003] At present, in the airbag polishing process, the spherical airbag processing is mostly used (Chinese patent CN102825543A). When the sph...
