Problems solved by technology

Although this type of tire frame can realize height adjustment and reuse, its height adjustment is discontinuous and the precision is low;
[0005] Through the analysis of various general-purpose tire frames in the prior art, it can be seen that there are still problems in the following aspects: 1. The adjustment accuracy of the type value of the tire frame is limited, and the operation is inconvenient; Automate

Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 1 Shown is the flow chart of the numerically controlled tire frame control method for shipbuilding of the present invention, which includes:

[0028] S101. Using the data interface technology to read the segmented surface data of the ship;

[0029] Using the data interface technology, it can interface with the ship segment data files directly output from the digital shipbuilding system widely used by shipyards, and directly read the model value data of the ship segment from these files, and apply it to the ship segment surface generate;

[0030] S102. Use NURBS technology to perform surface fitting on the read ship segmented surface data, and display the actual space position of the ship segmented surface on the screen;

[0031] In this step, NURBS technology is used to obtain the control points and control coef...

Abstract

The invention discloses a controlling method of a numerical control jig frame for ship building. The numerical control jig frame comprises a plurality of jig frame supporting columns. The controlling method includes the steps of (1) reading ship subsection curved-surface data, (2) carrying out curved-surface fitting on the read ship subsection curved-surface data, (3) adjusting the read ship subsection curved-surface data to be at the horizontal position through coordinate transformation, (4) determining specific coordinates of the jig frame supporting columns, (5) obtaining a curved-surface function of a ship subsection curved surface in a fitting mode through the bicubic NURBS technology and the data interpolation technology according to the ship subsection curved-surface data adjusted to be at the horizontal position, (6) calculating the deserved heights of the jig frame supporting columns, and (7) adjusting the jig frame supporting columns according to the calculated heights of the jig frame supporting columns. According to the controlling method, automatic control over the numerical control jig frame can be achieved, the height of the numerical control jig frame can be conveniently adjusted, and the controlling method is high in control and adjustment accuracy and control and adjustment speed.

Description

[technical field] [0001] The invention relates to a shipbuilding process, in particular to a control method of a numerically controlled tire frame for shipbuilding. [Background technique] [0002] In the process of ship construction, the tire frame is an indispensable tooling equipment for the assembly and welding of ship segments, and it is the shape tire mold and workbench for manufacturing hull curved segments and curved three-dimensional segments. There are many types of tire racks, which can be divided into two categories: special tire racks and general tire racks according to their scope of use. In our country, most of the shipyards use the fulcrum angle steel frame. In order to meet the requirements of the specific segmented surface line type, this special tire frame needs to weld and cut the angle steel fulcrum, which inevitably causes waste of steel. In my country In the case of a huge annual shipbuilding volume, the cutting of the fulcrum angle steel causes a huge ...
