High-precision measuring instrument for larger-scale structure component

The invention provides a technical scheme of a high-precision measuring instrument for a larger-scale structure component. The high-precision measuring instrument comprises a measuring instrument body, a positioning device and a high-precision micrometer. The measuring instrument body is formed by welding high-strength steel pipes; the measuring instrument body is formed by a cross beam and two supports; the cross beam of the measuring instrument body is in a triangle shape; the end portions of the two supports of the measuring instrument body are in triangle structures; and one support is connected with the positioning device, and the other support is connected with the high-precision micrometer. The measuring instrument can measure a large-scale measurement surface of the large-scale structure component, and the measurement precision is high. 本发明提供了种大型结构件的高精度测量仪器的技术方案，该方案包括测量仪器本体、定位装置和高精度千分尺；所述测量仪器本体由高强钢管焊接而成，所述测量仪器本体由横梁和两个支架构成，所述测量仪器本体的横梁整体呈三角形，该测量仪器本体的两个支架端部均为三角形构造，个支架与定位装置相连，另个支架与高精度千分尺相连。使用本方案能够测量大型结构件大
