Problems solved by technology

Due to the large number of outer panels in these sections, and there are no other positioning reference objects for direct reference, it is necessary to mark the ground line before installation, and the positioning of each outer panel takes a long time, and it is easy to Affected by auxiliary tools such as feet and steps, it takes more time cycles
If these outer plates cannot be accurately positioned, each outer plate will have a certain installation deviation, so the accumulation of installation deviations of several outer plates will lead to the occurrence of out-of-tolerance clearance and misalignment of the outer plates when the assembly is installed

Abstract

The invention discloses a bulk outer plate positioning method, which comprises the following steps of: marking an outer plate positioning mark on a segmented internal component of a segmented three-dimensional model, and then generating a segmented internal component processing drawing by utilizing the segmented three-dimensional model with the outer plate positioning mark; a numerical control machine tool can be directly used for cutting the segmented internal components with the outer plate positioning holes or the outer plate positioning lines, when the segments are built, relevant marks such as ground lines do not need to be surveyed on the ground below the segments, and the bulk outer plates can be accurately positioned by directly using the outer plate positioning holes or the outer plate positioning lines on the segmented internal components. A large amount of auxiliary work is reduced, meanwhile, the installation precision and the installation efficiency of the bulk outer plates are improved, and the situation that gaps of the outer plates are out of tolerance and staggered when the outer plates are assembled and carried is avoided.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a positioning method for bulk outer plates. Background technique [0002] In modern shipbuilding, more than half of the subsections include the installation of outer plates. There are currently three ways to install the outer panels: 1. Straight outer panels without linearity. For this kind of outer panels, we usually adopt the method of assembling the panels first and then installing them; 2. The outer panels with large changes in curvature and linearity. For this kind of segmented outer plate, the curved tire frame is usually manufactured (also by assembling the outer plate first and then installing the components); 3. The outer plate with relatively small curvature change is usually reversed with the platform surface as the tire frame surface. The way to build and then loosely stick the outer panels. [0003] When positioning and installing the above three kinds of oute...
