Sub-mirror assembling and disassembling device for segmented mirror of large astronomical telescope

Abstract

A Ssub-mirror assembling and disassembling deviceequipment for a segmented mirror of a large astronomical telescope is characterized in that a high-speed large-displacement robot and a minutesmall-displacement high-precision positioning robot form a series robot, the high-speed large-displacement robot adopts a hydraulic lifting and descending retractor device and is provided with two telescopic arms, the minutesmall-displacement high-accuracy positioning robot is mounted at the tail ends of the two telescopic arms, and adopts a motor lead screw device provided with a three-claw manipulator, and a vertical rotation device, a vertical lifting device, a horizontal adjustment device and a pitching mechanism are arranged between the three-claw manipulator and a manipulator chassis. The sub-mirror assembling and disassembling equipment makes up for the deficiency of the prior art, completely replaces original manpower for operation, realizes assembling and disassembling of sub mirrors of a primary mirror of an LAMOST (Large Sky Area Multi-object Fiber Spectroscopic Telescope), can meet the requirement of high-precision high-reliability mirror splicing of the primary mirror of the telescope, and meanwhile provides experience for mirror assembling of a large telescope in future.

Description

technical field [0001] The invention relates to a loading and unloading device. In particular, it relates to a device used in a method for loading and unloading splicing mirrors and sub-mirrors of a large astronomical telescope. It is suitable for the loading and unloading of the spliced ​​mirror and sub-mirror of Guo Shoujing Telescope (LAMOST). Background technique [0002] As the embodiment of a country's national strength and scientific and technological strength, astronomical telescopes have concentrated the latest achievements of contemporary high-tech such as large-scale optical glass casting, precision optical processing and testing, high-precision processing of large-scale mechanical equipment, computer control systems, and photoelectric receiving systems. The light-gathering aperture is the most important technical index of the telescope, and the development of the telescope is largely reflected in the continuous enlargement of the aperture. In order to break thr...

Problems solved by technology

[0012] 2. The entire main mirror MB is inclined downward at 25 degrees;

[0013] 3. There is no frame and tracking part of a general telescope, but it still needs to provide a stable downward-sloping support for the mirror room truss;

According to general mechanical knowledge, it is contradictory and difficult to take into account these two points in the design; taking into account the requirements of large displacement and high precision also brings difficulties to the control system
