Embodiment Construction

[0042] Below in conjunction with the closing pipe of the ship as an example, the present invention will be further described in conjunction with the accompanying drawings.

[0043] In the example, such as figure 1 , figure 2 , image 3As shown, a flange position measuring instrument is used to detect the spatial posture of the No. 1 flange and the No. 2 flange, including a panel 1, and the panel 1 is provided with a fixing device for positioning with the No. 1 flange. A stay wire displacement sensor 2 is provided on the panel 1, and the panel 1 is equipped with three non-collinear measurement reference columns 3, and the stay wires of the stay wire displacement sensor 2 can respectively bypass the measurement reference column 3 to the No. 2 flange. The flange position measuring instrument of this embodiment uses three measurement reference columns 3 arranged on the panel 1 as reference points, compared with the active reference points of the existing measuring device, becau...

Abstract

The invention discloses a flange position measuring instrument and a flanged pipe fitting reshaping machine. According to the flange position measuring instrument, three measurement reference columns are arranged on a face plate to be used as reference points, compared with movable reference columns of an existing flange position measuring device, because the positions of the measuring reference columns are fixed, the flange position measuring instrument is smaller in system error during measurement, and the calculation burden is lighter when the space attitude of the flange is calculated according to measured data. In this way, the flanged pipe fitting reshaping machine combined with the flange position measuring instrument is higher in machining precision and shape adjusting precision, and the yield of flanged pipe fitting products is significantly improved.

Description

technical field [0001] The invention relates to the technical fields of steel structure, shipbuilding and maintenance, and in particular to a flange position measuring instrument and a pipe calibrating machine for flange pipe fittings. Background technique [0002] Flanged pipe fittings refer to pipe fittings with flanges (flanges or lands), which are used to match pipes. Most of them are welded pipe fittings, which are commonly used in steel structures, marine engineering, transportation pipelines and other fields. [0003] Taking a ship as an example, the ship is full of pipelines, and a series of operations such as the design, manufacture, and inspection of these pipe fittings after installation in the ship are called "pipeline laying". Usually ships are built in sections, and the pipelines in each section are lofted pipes. When the sections are closed, the pipelines between the sections need to be connected by closing pipes, but relying on the pipeline design drawings ca...
