Embodiment 1

[0031] Such as image 3 As shown, in this embodiment, the case that the lengths of each card-like line type are consistent is described, and the method for obtaining the card-like alignment point of the quasi-parallel line type includes the following steps:

[0032] S1: The middle position of the first card-like line pattern 11 is used as the first perpendicular line, and the middle position of the tail card-like line pattern 12 is used as the tail perpendicular line, and the first perpendicular line and the tail perpendicular line are parallel;

[0033] Specifically, there are a total of four clamping line types in this embodiment. It should be noted that the clamping line type is the line type part of the curved panel intercepted at the position of the rib line type. In this embodiment, there are a total of four A part of the line type of the curved panel is intercepted at the line type. The ends of the four clamping line types are all drawn with a plate seam 2, which is eq...

Embodiment 2

[0049] Such as Figure 4 As shown, in this embodiment, the situation that the lengths of each card-like line type are greatly different is described. The method for calculating the card-like alignment point of the quasi-parallel line type in this embodiment includes the following steps:

[0050] S1: The middle position of the first card-like line pattern 11 is used as the first perpendicular line, and the middle position of the tail card-like line pattern 12 is used as the tail perpendicular line, and the first perpendicular line and the tail perpendicular line are parallel;

[0051] Specifically, this embodiment also includes four parallel card-like line types, the four card-like line types are respectively curve F1, curve F2, curve F3 and curve F4, and the lengths of curve F4, curve F3, curve F2 and curve F1 They gradually become longer in order, among which the curve F4 is the shortest and the curve F1 is the longest. At the middle positions of the curve F4 and the curve F...

Abstract

The invention relates to a method for obtaining a quasi-parallel line type card-like directrix point. It includes the following steps: S1: make the first perpendicular through the middle position of the first card-like line type, and make the tail perpendicular line through the middle position of the tail card-like line type, and the first perpendicular line and the tail perpendicular line are parallel; S2: take the first card-like line The intersection point of the type and the first perpendicular line is taken as the starting point to intercept the set length on the first perpendicular line to create the first card sample rod, and the intersection point of the end card sample line type and the tail perpendicular line is used as the starting point to intercept the set length on the tail perpendicular line to create Tail card-like rod; S3: according to the number of card-like line types between the first card-like line type and the last card-like line type, create an equal number of equal points on the line segment between the first guideline point and the last guideline point , each bisection point is the directrix point corresponding to the card-like line type. The method for obtaining the directrix points of quasi-parallel line types in the present invention provides a method for obtaining directrix points specifically for quasi-parallel line types, which makes it easier to obtain the directrix points of quasi-parallel line types. Reasonable, improve the processing accuracy of the plate.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a method for obtaining a quasi-parallel-line card-like alignment point. Background technique [0002] In the process of ship construction, there are many curved plates similar to the outer plates of the hull that need to be processed. In order to ensure the processing accuracy of these curved plates, these curved plates usually need to process multiple clamping samples of the curved plates before processing ( Wooden card), by arranging these card samples on the corresponding rib position line, the rough outline of the curved plate can be pieced together, so as to realize the positioning of the bending accuracy of the plate, and the processing of each card sample requires the card of the reference design The important step of the line type and the line type of the card sample is to determine the alignment point of the sample line, but at present, the determination of the align...
