Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0018] A method for quickly inspecting the installation of curved surface segmented components by using perspective lines, comprising the following steps:

[0019] ①According to the design, design a certain longitudinal section on the component to be installed. The longitudinal section line intersecting the longitudinal section with the component to be installed is the added perspective line. When processing the installation components in sections, increase the perspective Line powder painting line;

[0020] ② Measure the angles of the segmented bow end face member and stern end face member respectively by means of a hammer and ruler to determine the accurate positioning angle;

[0021] ③ When installing the components inside the section in the middle area, observe the fro...

Abstract

The invention discloses a method for mounting and quickly detecting curved-surface segmentation member through perspective rays. Curved-surface segmentation for assembling and positioning is finished on a scaffold; the segmentation member is provided with the perspective ray in a scribing manner in a sleeve material processing stage, so that the aims of checking the segmentation torsion and a member mounting angle by eyes are fulfilled without other measurement tools. The method disclosed by the invention is simple and is convenient to use; the complicated measurement work of the conventional curved-surface segmentation manufacturing stage is simplified; the segmentation assembling efficiency and the segmentation mounting precision and quality are improved.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for quickly inspecting the installation of curved surface segmented components by using perspective lines. Background technique [0002] In the process of ship segmental construction, a large number of hyperbolic oblique segments and small side segments are difficult precision problems in product precision control. Due to the large linear shape of the tire frame surface, and the double oblique cutting of the tire frame. If the frame is installed on the base surface, it is difficult to guarantee the assembly and positioning accuracy, and the misalignment of the installation angle of the ribs often occurs, which affects the loading accuracy of the berth. When checking the installation accuracy of such components, the detection method is complicated and consumes a lot of time, which greatly affects the production efficiency. Contents of the invention [0003] The purpose of the present i...
