Description

Technical Field

[0001] The utility model relates to a device in the field of measuring mechanical equipment parameters, in particular to a device for measuring the dimensional parameters of a V-shaped base. Background Technique

[0002] In the process of ship production and processing, V-shaped bases are often used to carry the hull structure, so there are high requirements for parameters such as their angles, flatness, and symmetry. At present, if workers want to measure the above parameters, they usually need to first find the center line plane on the hull structure, then correspondingly obtain the center line plane of the V-shaped base, set up a tooling as the reference for the center line plane, and then measure the symmetry of the working planes on both sides of the V-shaped base with a meter ruler. Similarly, when measuring the angle of the working plane of the V-shaped base, a tooling on the horizontal plane is also set up first, and then a conventional angle ruler and a knife ruler are used for measurement.

[0003] The measurement method of setting up tooling as the reference for the hull center line plane or the horizontal plane has large measurement errors itself, and is time-consuming and laborious during the construction process, prolonging the construction period and resulting in an increase in construction costs. At the same time, the measuring tools are not convenient for direct viewing, and there are errors in the measuring tools themselves, which will ultimately lead to a further increase in measurement errors. Therefore, how to quickly and accurately measure the parameters such as the angle, flatness, and symmetry of the V-shaped base, facilitate the measurement of the dimensions before processing the V-shaped base, the re-inspection of the dimensions during processing, and the verification of the dimensions after processing, and improve the construction efficiency has become an urgent problem to be solved.
