Abstract

A polishing rubber disc face shape detection device for a large annular polishing machine comprises a straight guide rail, a laser device, a lens set, an illumination slit, a light splitting prism, a pentagonal prism, a rectangular prism, a base, a CCD, a displacement regulation device, a movable table and a telescopic sleeve. The polishing rubber disc face shape detection device can detect the face shape of a polishing rubber disc of the large annular polishing machine and is simple in structure, convenient to operate, stable, reliable and high in accuracy, safety of workpieces is ensured in the workpiece carrying process, and damage caused when external impurities are led to the surfaces of the workpieces is avoided.

Description

technical field [0001] The invention relates to a large ring polishing machine, in particular to a detection device for the surface shape of a polishing rubber disc of a large ring polishing machine. Background technique [0002] The ring polishing machine is almost the only processing equipment in the world that can process large-caliber planar optical elements globally. It rotates the workpiece to be polished relative to the polishing rubber disc under the action of its own gravity and polishing liquid. The mechanical grinding action and the physical and chemical action of the solution complete the material removal on the surface of the workpiece and obtain a smooth surface. Compared with other technologies, this technology can realize the global planarization of large-diameter workpieces at the same time, and can eliminate high-point and wave-shaped unevenness on the surface of the workpiece, and can also eliminate high-frequency defects, so that the surface processing qu...
