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 F1, curve F2, curve F3 and curve F4 The side lengths are gradually increased in order, wherein the curve F1 is the shortest and the curve F4 is the longest. Make the first perpendicular and the tail perpe...

Abstract

The invention relates to a quasi-parallel linetype clamp-sample alignment point obtaining method. The method comprises the following steps: S1: drawing a forward-perpendicular passing through the middle position of a head clamp-sample linetype, and drawing an after-perpendicular passing through the middle position of a tail clamp-sample linetype, wherein the forward-perpendicular is parallel to the after-perpendicular; S2: intercepting a set length on the forward-perpendicular by taking the intersection point of the head clamp-sample linetype and the forward-perpendicular as a starting point to create a head clamp-sample rod, and intercepting the set length on the after-perpendicular by taking the intersection point of the tail clamp-sample linetype and the after-perpendicular as the starting point to create a tail clamp-sample rod; and S3, creating equal division points with equal numbers on line segments between a head alignment point and a tail alignment point according to the number of the clamp-sample linetypes between the head clamp-sample linetype and the tail clamp-sample linetype, wherein each equal division point is the alignment point corresponding to the clamp-sample linetype. According to quasi-parallel linetype clamp-sample alignment point obtaining method in the invention, the alignment point obtaining mode special for the quasi-parallel clamp-sample linetype is given, so that the alignment points of the quasi-parallel clamp-sample linetypes are more reasonable in obtaining, and the processing precision of plates is improved.

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...
