The invention relates to a hydraulic-electric combined-adjusting supporting and height-adjusting integration device for optical primary mirror processing. The hydraulic-electric combined-adjusting supporting and height-adjusting integration device for optical primary mirror processing comprises a thin film hydraulic cylinder and a height-adjusting base, wherein the thin film hydraulic cylinder comprises a radial constraint linear bearing, a bearing fixing end cover, an elastic material, an upper cylinder body and a lower cylinder body; the height-adjusting base comprises a rotary sleeve, a bottom plate, a positioning and guiding flat key and an outer ring gear; the rotary sleeve sleeves on the bottom plate in a clearance fit way; the outer ring gear is connected with a motor; an inner holein the upper part of the rotary sleeve is connected with outer walls of the upper cylinder body and the lower cylinder body through a screw pair; and a slot in clearance fit to the guiding and positioning flat key is formed in the outer walls of the upper cylinder body and the lower cylinder body. When the hydraulic-electric combined-adjusting supporting and height-adjusting integration device for optical primary mirror processing provided by the invention is applied to a large-diameter optical primary mirror processing process, hydraulic Whiffletree supporting is realized, a floating supportforce is provided for primary mirror processing, and the influence of an internal friction force of the hydraulic cylinder and elastic deformation of the device on a supporting system is greatly limited; and meanwhile, a hydraulic-electric combined-adjusting manner is adopted, so that the supporting height during the processing process can be conveniently and accurately adjusted.
Description
technical field [0001] The invention relates to a supporting and height-adjusting structure for optical primary mirror processing, in particular to a hydraulic-electric joint adjustment support and height-adjusting integrated device for optical primary mirror processing. Background technique [0002] Ground-based large-aperture optical telescopes are currently an important technical means for astronomical observations, and the size of the telescope's optical primary mirror directly restricts the observation capabilities of the telescope. At present, my country's mature primary mirror processing technology still stays below 2m in diameter. The processing of the optical primary mirror above 2m generally adopts the passive support method, and the hydraulic Whiffletree support method is a commonly used and reliable passive support method, and the resistance and stiffness factors of the support and height adjustment unit directly affect the support effect of this support method, ...
