Abstract

The invention discloses a vertically-arranged two-dimensional large-stroke rapid moving device for repairing microdefects of the surface of a large-caliber hook-face optical element, and relates to a two-dimensional large-stroke rapid moving device. The problems that in the existing optical element laser repairing process, the movement speed of a two-dimensional large-stroke rapid moving device is low among three stations, and installation errors are caused by multiple times of clamping are solved. An X-axis servo motor drives an X-axis movement guide rail to linearly move in the X-axis direction. A load bearing plate is fixed to a guide rail sliding table. A portal frame structure is formed by two stand columns and a transverse portal plate. A closed structure is defined by two vertical portal plates, portal rib plates and the transverse portal plate. Two Y-axis movement guide rails are fixed to the inner sides of the two stand columns respectively. A Y-axis servo motor drives one Y-axis movement guide rail to vertically move. A left border and a right border of a load bearing frame are fixed to guide rail sliding tables of the two Y-axis movement guide rails respectively. The vertically-arranged two-dimensional large-stroke rapid moving device is suitable for repairing the microdefects of the surface of the large-caliber hook-face optical element.

Description

Technical field [0001] The invention relates to a two-dimensional large-stroke fast moving device. Background technique [0002] With the increasing depletion of fossil energy, nuclear fusion energy has become the most ideal future energy source for mankind due to its inexhaustible and clean advantages. Fused silica with excellent optical properties, as the core optical component of strong laser output, plays an important role in the inertial confinement nuclear fusion device. However, in the process of ultra-precision machining and laser targeting, the surface of fused silica is prone to micro-cracks or ablation and other forms of micro-defects. If no measures are taken to deal with them in time, these micro-defects will continue to grow in the subsequent laser targeting process, and eventually lead to damage to the entire optical element. In order to increase the service life of fused silica optical components, the Lawrence Livermore National Laboratory (LLNL) of the United S...
