Deviation Correction Method for Angle Scale of Large Jigsaw Board

Abstract

The invention provides an error correcting method for the uniform angle index of a large spliced plate. The method is used to detect and control the uniform angle index of the large spliced plate, and provides a technical scheme. Whether a prism or isosceles trapezoid phenomenon or a size deviation phenomenon exists in the plate is determined by utilizing the Pythagorean theorem, a unique point is determined via the fixed size of a right angled triangle, the relative position of the large spliced plate is adjusted, technical processing can be carried out before completion of plate splicing, and it is ensured that a qualified large spliced plate is provided for subsequent procedures. The method is easy to understand and simple in operation; problems in the uniform angle index of the spliced plate can be timely discovered; solution measures can be adopted timely and effectively; the problems that aligning lines and examination lines which are marked after plate splicing and used for subsequent procedures deviate with deviation of the edge lines of the plate and that the precision of the subsequent procedures is hard to control are solved; and the construction quality of the link is ensured.

Description

technical field [0001] The invention relates to a method for splicing, positioning, and correcting large panels, and more particularly, to a method for correcting the angular scale of large panels of steel plates in the field of ships and ocean engineering. Background technique [0002] Ships and ocean engineering are very complicated, and their carrier is a steel structure. Usually, the steel structure will be divided into several small sections for construction, and then assembled into a finished steel structure. During the whole process, the segment exists as an intermediate product; and in the segmented construction process, the splicing of steel plates is a very critical starting point, and the quality of the construction directly affects the follow-up work. Therefore, controlling the angular scale of the jigsaw puzzle is a very important link in the hull precision management. In the previous process of the jigsaw panel, the steel plate is usually cut by a CNC cutting ...
