Pipe calibration platform instrument

Abstract

The invention discloses a pipe calibration platform instrument, which is characterized in that it includes a fixed installation platform and several measuring devices, and the fixed installation platform includes a horizontal reference plate with X scale lines and Y scale lines and a horizontal reference plate perpendicular to the horizontal reference plate. Consisting of a vertical reference plate, the vertical reference plate is provided with a connecting hole for fixing the mounting flange of the measured pipe fitting, the measuring device includes a scale column, and a base that can be fixed on the horizontal reference plate, the base is provided with a panel, The scale column is provided with an infrared projector that can slide up and down along the scale column, and a rotation angle disc is fixed at the lower end of the scale column, and the rotation angle disc is connected with the panel and can rotate relative to the panel.

Description

technical field [0001] The invention relates to a calibrating instrument, in particular to a pipe calibrating platform instrument. Background technique [0002] At present, there are mainly two kinds of routine pipe inspection methods in shipyards: [0003] (1) Use the circle scale on the ground to directly measure the length of each bending node on the pipe, and measure the angle with the compass. [0004] (2) Fix the pipe on the platform, and measure the X, Y, Z dimensions of the pipe with a ruler to check the accuracy of the pipe. [0005] Although the above two inspection methods are relatively convenient, since the pipe is staked out by 3D stereo software and then measured after production, the pipe is easy to move during the measurement process, and the operator is different, use a ruler, square, compass, etc. to measure It is difficult to accurately check the correctness of the pipe, so the measurement accuracy is not high, and there are large errors, especially in ...

Problems solved by technology

[0005] Although the above two inspection methods are relatively convenient, since the pipe is staked out by 3D stereo software and then measured after production, the pipe is easy to move during the measurement process, and the operator is different, use a ruler, square, compass, etc. to measure It is difficult to accurately check the correctness of the pipe, so the measurement accuracy is not high, and there are large errors, especially in the position where the three angles are bent, the error is not discovered until after the pipe is shipped, which increases the cost of modification and prolongs the shipbuilding period. The positioning of each pipe and valve in a particularly modern modular shipbuilding must be very accurate. For the modern shipbuilding industry, advanced design software, digital manufacturing, and inspection tools are still backward methods.

Difficult to adapt to modern modular shipbuilding

[0006] The purpose of the machine calibration platform instrument of the present invention is mainly to solve the problems of low pipe inspection accuracy, inconvenient operation, and high inspection cost, and to study the rapid simulation installation of pipes, to check the structure of the projector and the versatility of the device of the present invention, thereby Enable inspectors to quickly and accurately verify the finished pipe or all links in the pipe production process, improve the production quality of shipyard pipes, reduce labor costs, and shorten the shipbuilding cycle
