Flexible airbag grinding and polishing tool with multiple motion freedom degrees

Abstract

The invention discloses a flexible airbag grinding and polishing tool with multiple motion freedom degrees. A mechanical arm mechanism is adopted for replacing a traditional machine tool to carry outauxiliary moving to achieve optical machining. The flexible airbag grinding and polishing tool mainly comprises a slewing mechanism, a parallel mechanical arm mechanism, a wrist swing mechanism, a transmission mechanism, a resin ball grinding tool head and an airbag polishing tool head. According to the flexible airbag grinding and polishing tool, the mechanical arm device with the four freedom degrees is adopted for achieving space moving and swinging of the tool heads, and fast switching between grinding and polishing is achieved by replacing the machining tool heads easily and conveniently.The whole set of machining system from feeding to grinding and then to polishing of workpieces can be achieved finally.

Description

technical field [0001] The invention discloses an airbag flexible lapping and polishing tool with multiple degrees of freedom of movement, which can realize a complete set of processing system from raw material, rough grinding, fine grinding to polishing. technical background [0002] With the continuous advancement of science and technology, modern optical systems have become more and more complex, and the requirements for optical components that make up the optical system have also become higher and higher, for example: ultra-large diameter ultra-thin ultra-smooth surfaces, free-form surfaces of specific shapes Surface shape, etc.; and because optoelectronic instruments are more and more widely used in many fields such as aviation, aerospace, electronics, astronomy, lasers, and optical communications, precision optoelectronic instruments are moving towards high performance, wide range of operating wavelengths, and high digitalization. Development, driven by many factors, t...

Problems solved by technology

[0003] The current polishing technology is greatly affected by the surface accuracy of the material after grinding, which directly affects the removal efficiency and quality of polishing. Moreover, the two stages of grinding and polishing are processed on different machine tools, and the process often cannot achieve a good connection.

In addition, the space positioning of traditional CNC machine tools is relatively heavy, the structure is large and complex, and the flexibility is poor
