The invention discloses a double-flexible self-adaptive polishing grinding head which belongs to the technical field of optical cold processing, aims to solve the problem of unmatched polishing grinding head surface and workpiece surface of the prior art, and has improved polishing quality. The grinding head comprises a polishing spindle, a connecting flange, a spring, a fastening bolt, a rigid base, a flexible layer, a rigid layer and a polishing layer; and the polishing spindle is slidably connected with the connecting flange, the connecting flange is tightly connected with the rigid base through the fastening bolt, the polishing spindle, the connecting flange and the rigid base are coaxial, the spring is positioned in the connecting flange and between the polishing spindle and the rigid base, and the flexible layer, the rigid layer and the polishing layer are sequentially arrayed below the rigid base. The self errors of a machine tool and a workpiece or caused by debugging are automatically compensated through the elastic deformation of the spring, so that the high-precision surface processing of aspheric surface elements is realized.
Description
technical field [0001] The invention relates to a dual-flexible self-adaptive polishing grinding head, which belongs to the technical field of optical cold processing. Background technique [0002] Aspherical polishing is a difficult point in optical cold processing. During the polishing process, the polishing mold is usually attached to the surface of the workpiece, and at the same time, a high-speed relative movement is performed to generate a tangential force, so that the tiny protrusions on the glass surface are cut; due to the different curvature radii of each point of the aspheric equation, the polishing grinding head is very It is difficult to achieve a perfect match with an aspheric surface, therefore, it is impossible to obtain a high-precision aspheric optical element. The computer-controlled surface forming technology commonly used at present mainly uses small grinding heads for polishing, and the polishing path trajectory is fixed, so medium and high frequency e...
