Description

Technical Field

[0001] The present invention belongs to the technical field of machining tooling, and particularly relates to a special scribing tooling and a scribing method for assembling T-shaped profiles. Background Art

[0002] During the shipbuilding process, T-shaped profiles are extremely common structures in the hull structure. Usually, the assembly volume of T-shaped profiles on a ship is particularly large, and the labor, material, and working hours consumed account for a relatively large proportion. As the first step in the assembly of T-shaped profiles, the speed and accuracy of scribing are of great significance for subsequent work. Currently, the commonly used scribing tools during construction are tape measures or square rulers. During construction, multiple marking lines are measured on the T-shaped profile panel with a tape measure or a square ruler, and then the marking lines are connected together to form installation lines. The above work not only requires two people to cooperate, which is time-consuming and laborious, but also has low work efficiency and is prone to errors, and cannot achieve the speed and accuracy of scribing.

[0003] Due to the special cross-sectional shape of T-shaped profiles, precise scribing and positioning of their horizontal and vertical sides are required during assembly. Traditional tooling mostly adopts a fixed limit structure, which has the following defects: it cannot adapt to T-shaped profiles of different sizes, and the tooling needs to be frequently replaced, resulting in low efficiency; cumulative errors are easily generated during manual calibration of right-angle positioning, affecting the assembly accuracy; the limit components are easily worn and have high maintenance costs.

[0004] Therefore, how to provide a special scribing tooling and a scribing method for assembling T-shaped profiles, which can achieve single-person rapid scribing of flat and curved T-shaped panels, with a simple and effective tooling usage method and low manufacturing cost, reducing costs and increasing efficiency, has become an urgent technical problem to be solved.
