Abstract

The invention discloses an eccentric planetary polishing device of a large-caliber aspheric robot. The main structure of the eccentric planetary polishing device is composed of an eccentric planetary transmission mechanism and a polishing shaft assembly. The eccentric planetary transmission mechanism achieves revolution motion and rotation motion of end execution of the polishing device at the same time through the same motor and comprises a planetary transmission mechanism body and a mass center balance mechanism, and dynamic balance stability during mechanism operating can be achieved. The polishing shaft assembly is composed of a low-friction air cylinder, a rotary ball spline and a polishing hollow shaft. The polishing hollow shaft can inject a polishing solution to a polishing disc during polishing, and therefore dynamic-pressure and static-pressure polishing is achieved. The influence of friction force on the polishing shaft of a pure rolling connection manner under pressure control is low, and therefore high control precision is achieved.

Description

technical field [0001] The invention belongs to the fields of precision machinery and optical processing and manufacturing, and is an end device dedicated to optimizing robot polishing, which is suitable for precision polishing of large-diameter aspheric elements. Background technique [0002] Astronomy and space exploration technology play an extremely important role in the development of science and technology, and advanced optical instruments have always been the key parts supporting their development. With the development of science and technology, the requirements for components are getting higher and higher, and large-aperture aspheric optical components with high precision have become more and more indispensable components. Computer-controlled surface molding technology, compared with traditional optical processing technology, not only has the ability to process high-precision components, but also can greatly improve processing efficiency, so it has become the main me...
