Abstract

An ultra-precise processing integrated platform for a large caliber optical mirror surface solves the problem that processing and detection are not integrated while processing the large caliber optical mirror surface in the conventional optical processing technical field. The platform integrates grinding, detection and milling for processing the large caliber optical mirror surface, and comprises a base, a horizontal moving device, a rotation device, an ultra-precise grinding device, a mirror surface detection device and a milling device, wherein the horizontal moving device drives the rotation device to move to a workpiece mounting position, a grinding position, a surface shape detection position and a milling position in a horizontal direction; a vertical moving device drives a spindle system and a diamond grinding wheel to move up and down in a vertical direction; the spindle system can adjust the inclined angle of the diamond grinding wheel; the diamond grinding wheel has a cambered surface; when in the workpiece mounting position, the rotation device can conduct cambered surface grinding on a workpiece; when in the surface shape detection position, the rotation device can conduct surface shape detection on the workpiece; when in the surface shape detection position, the rotation device can mill the workpiece.

Description

technical field [0001] The invention relates to a device in the technical field of optical processing, in particular to an integrated platform for ultra-precision processing of large-diameter optical mirror surfaces. Background technique [0002] The development of space technologies such as astronomical instruments, satellites, and space-based monitors has put forward higher and higher requirements for space optical systems. In order to increase the resolution, the optical system needs to use a large-diameter mirror. In the cold processing of astronomical optics, it is customary to call a mirror with a diameter of φ300mm or more as a large-diameter mirror. The quality of the surface and sub-surface of the mirror has a decisive impact on the observation effect of the optical system. . Optical mirror processing is generally divided into grinding, grinding and polishing stages, among which grinding and grinding belong to forming processing, which has a great impact on the sur...
