Polishing head

Abstract

The invention relates to a polishing grinding head. The polishing grinding head comprises a revolution mechanism and an autoroatation mechanism clamped to the revolution mechanism in a sliding manner, and the autoroatation axis of the autoroatation mechanism deviates from the rotation axis of the revolution mechanism; the autoroatation mechanism comprises a polishing disc installed at the bottom; and the polishing grinding head further comprises a pneumatic constant-pressure device connected with the autoroatation mechanism and used for stabilizing the polishing pressure. According to the polishing grinding head, a planetary motion structure manner is adopted, and through autoroatation and revolution motor motion, adjustment at any speed ratio is achieved; and meanwhile, internal air pressure adjustment is adopted, the stably-output polishing pressure is obtained, and further the adaptability to the shape changes of the surface of a machined workpiece is further strengthened. As the grinding adaptability is improved, as long as the grinding parameters are correspondingly adjusted, different grinding requirements can be met, and the grinding efficiency is improved; and in addition, during grinding, through matching of autoroatation and revolution and stabilized adjustment of the air pressure, the effect of improving the stability of the removal function is achieved.

Description

Technical field [0001] The invention relates to optical lens processing technology, and more specifically, to a grinding and polishing head. Background technique [0002] In modern optical lens processing technology, grinding machines are generally used for processing. However, the existing grinding machine has the problems of low polishing efficiency and unstable removal function in the processing process, especially when working with robots, it is difficult to perform local repair and polishing of large-diameter aspheric lenses. [0003] Among the entire set of optical lens processing equipment, the one that has the greatest impact on the above-mentioned polishing efficiency and the stability of the removal function is the end effector-the polishing head, its mechanical structure, movement mode, pressure mode, and size of the grinding disc. , Eccentricity and other parameters directly determine the removal function, work efficiency and machining accuracy of the grinding and poli...
