Abstract

The invention discloses a forced centering device for precision engineering measurement. The forced centering device comprises a fixing plate, two groups of box bodies are arranged at the upper part of the fixing plate; the box bodies are parallel to each other and are installed at the upper end and the lower end of the fixing plate. A screw is arranged in each box body, a crank is arranged on theright side of the screw, a sliding block is arranged on the surface of the screw, a sliding groove is formed in the surface of each box body, the sliding block is slidably connected with the slidinggroove, a first movable shaft is arranged on the upper portion of the sliding block, a lifting rod is arranged in the first movable shaft, and a second movable shaft is arranged on the upper portion of the lifting rod. The supporting rods and the limiting rings are arranged on the lower portion of the mounting plate, and the limiting rings sleeves the surface of the telescopic rods;; due to the fact that the centering column structure is fixed, the balance of the centering disc can be guaranteed through the limiting rings, meanwhile, the surface of the silicon chip is provided with an embedding groove and a second threaded hole which are used for instrument connection, the silicon chip is connected with the first threaded column through the cover plate, and the protection effect is achieved when the silicon chip is not used.

Description

technical field

[0001] The invention relates to the technical field of engineering measurement, and more specifically relates to a forced centering device for precision engineering measurement. Background technique

[0002] Engineering survey is an important part of engineering construction, including control survey and topographic survey in the planning and design stage, construction survey, equipment installation survey and completion survey in the construction stage, deformation survey in the operation and management stage, etc. For large-scale projects and special projects, such as railways, tunnels, mines, bridges, and national defense projects, precision engineering measurement is required to meet the high standard requirements of engineering construction, positioning or deformation observation. In order to ensure the high precision of the observation data and the reliability of the results, precision engineering surveys generally do not use traditional temporary tripo...
