Abstract

The invention discloses a five-dimensional high-precision platform for installation testing of large gratings, and belongs to the technical field of high-precision adjusting devices. The platform is used for solving the problems that an existing installation testing platform for large gratings cannot achieve five-dimensional adjustment due to limitation caused by the center height, and an existing four-dimensional adjustment device is low in overall rigidity and poor in stability. Two x-axis photoelectric proximity switches are fixedly connected with a horizontal-movement base through two x-axis photoelectric proximity switch bases, two long guide rails of a crossed guide rail assembly are fixed to the horizontal-movement base, an inner side sliding base assembly is fixed among four cross sliding blocks of the crossed guide rail assembly, x-axis ball screw nuts of an x-axis horizontal-movement driving assembly are fixed to a sliding base body of the inner side sliding base assembly, a y-axis horizontal-movement driving assembly is fixedly connected with an assembly rotating around the x-axis, the y-axis and the z-axis and the inner side sliding base assembly, the assembly rotating around the x-axis, the y-axis and the z-axis is fixedly connected with two short guide rails of the crossed guide rail assembly, and a grating installation assembly is fixedly connected with the assembly rotating around the x-axis, the y-axis and the z-axis. The five-dimensional high-precision platform is used for installation testing of the large gratings.

Description

technical field [0001] The invention relates to a five-dimensional high-precision platform for grating installation and testing, and belongs to the technical field of high-precision adjustment devices. Background technique [0002] The high-precision large-size grating is a precise KDP crystal light-splitting element, which is the core component of the high-energy laser pulse device. The demand for the grating area has reached the meter level or even larger. The high-energy short-pulse laser device is a necessary tool to achieve fast ignition of inertial confinement fusion. The relative positions of each grating need to be adjusted to achieve high-energy short pulses. Therefore, an installation platform that can accurately adjust its relative position and attitude adjustment is required. The device needs to adjust five degrees of freedom at the same time to meet the requirements of the center height, and has sufficient rigidity and high positioning accuracy, as well as good ...
