Description

TECHNICAL FIELD

[0001] The utility model relates to optical glass polishing device technical field, in particular to a kind of polishing mechanism of polishing wheel replaceable. BACKGROUND

[0002] When polishing optical glass, it is usually necessary to replace polishing discs of different mesh or use polishing materials of different mesh to achieve ideal polishing effect. Polishing optical glass is generally divided into rough polishing, medium polishing and fine polishing stages. In the rough polishing stage, the purpose is to remove large defects, scratches and unevenness generated in the previous processing on the surface of optical glass. At this time, polishing discs or polishing materials with lower mesh (such as 100-400 mesh) are used.

[0003] At present, in most optical glass processing enterprises, the replacement of polishing discs mainly relies on manual operation. The operator needs to use wrench, screwdriver and other basic tools to disassemble and assemble the polishing disc. Although this traditional manual replacement method has certain flexibility and universality, it also has many drawbacks. When manually installing the polishing disc, the skill level and experience of the operator have a great influence on the installation precision. If the screws are not tightened evenly or installed in place, it may cause the polishing disc to shake or eccentric when rotating at high speed, thereby affecting the precision and quality of polishing, increasing the rate of defective products, and lacking convenience.
