Abstract

The invention discloses an automatic flexible assembling and calibration platform and method for a meter-scale reflector. The automatic flexible assembling and calibration platform for the meter-scalereflector comprises a base and a rotary table rotatably mounted on the upper portion of the base; the rotary table comprises an assembling panel and a jacking plate; a positioning pin which can be close to or far away from the jacking plate is arranged on the assembling panel in the circumferential direction of the jacking plate; a flexible cleaning pad is arranged on the upper surface of the jacking plate; and lock screw assemblies are arranged on the two sides of the assembling panel. By adopting the automatic flexible assembling and calibration platform and method for the meter-scale reflector, the problem in automatic flexible batch assembling and calibration of the meter-scale reflector is solved, the cleaning problem caused by manual intervention is avoided, the assembling and calibration efficiency is greatly improved, the pre-tightening forces in all positions of the reflector are uniform, the front-wave error caused by reflection is reduced, and the assembling and calibrationquality and stability of the reflector can be improved; and meanwhile, the assembling and calibration platform and method can be popularized and applied to the assembling and calibration process of other precise optical elements.

Description

technical field

[0001] The invention belongs to the technical field of precision assembly and calibration of meter-scale optical elements, and in particular relates to an automatic flexible assembly and calibration platform and an assembly method for meter-scale mirrors. Background technique

[0002] In high-power solid-state lasers, take the NIF large-scale laser facility in the United States as an example. In order to create the extreme high-temperature and high-pressure environment required for fusion to occur in the laboratory, this type of device consists of hundreds of high-energy solid-state lasers passing through an optical path of hundreds of meters. After that, it is accurately shot at the target ball with a diameter of a few millimeters. The time deviation of each beam of high-energy laser reaching the center of the target is less than 60ps, and the target error is less than 50μm. Such a high precision requirement is guaranteed by thousands of precision optical co...

Embodiment Construction

[0037] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0038] Such as Figure 1 ~ Figure 3 As shown, an automated flexible calibration platform for meter-scale mirrors includes a base 1 and a turntable 2 rotatably mounted on the upper part of the base 1. The turntable 2 includes an assembly panel located above the base 1 and rotatable relative to the base 1. 201 and a lifting plate 202 that can be lifted and lowered at the center of the assembly panel 201, on the assembly panel 201 along the circumferential direction of the lifting plate 202, there are positioning pins 203 that can approach or stay away from the lifting plate 202. A flexible cleaning pad 3 is provided on the upper surface of the lifting plate 202 , and locking screw assemblies 4 are provided on both sides of the assembly panel 201 .

[0039] See figure 2 and image 3 , a rotating base plate 204 and a lifting mother plate 205 are arranged in par...
