Problems solved by technology
However, the address setting device in this invention is relatively expensive, and its use environment requirements are also relatively high. For harsh environments such as shipyards, it will affect its precise positioning; It is difficult to adjust the height of the tire frame within the scope of the existing technology, so the cost of this invention is relatively expensive, and the practical value of the project is limited to a certain extent

Embodiment Construction
[0037]The making and using of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. The expression of the structural position of each component such as up, down, top, bottom, etc. in the description is not absolute, but relative. These directional expressions are appropriate when the various components are arranged as shown in the drawings, but when the positions of the various components in the drawings are changed, these directional expressions are also changed accordingly.
[0038] Such as Figure 1-5 As shown in the figure, a numerically controlled lifting and lowering hull segment positioning tire frame square matrix includes N×M groups of positioning tire frames and control systems arranged vertically and horizontally to form the square matrix, wherein N is an integer greater than 1, and M...

The invention discloses a numerical control lifting adjusting type positioning jig frame square matrix for ship sections. According to the positioning jig frame square matrix, a worm is driven to rotate by a motor, a turbine is driven to rotate by the worm, a jacking lead screw is driven to rotate by the turbine, a jacking guide rail is driven to move up and down by the jacking lead screw, and therefore, the accurate jacking positioning of structural sections of a large-scale ship is realized; and a traditional steel structural jig frame positioned through splicing welding is replaced with a numerical-control jacking device. A jig frame is designed and manufactured in a modularized manner, the height positioning size of the whole jig frame square matrix can be rapidly adjusted in a high precision manner, the jig frame square matrix is particularly suitable for complex curve surfaces of large-sized ship bodies and ocean platform sections, the production efficiency can be improved, and the ship manufacturing period can be shortened.
Description
technical field [0001] The invention relates to a tire frame for segmented positioning of a hull, in particular to a square matrix of tire frames for segmented positioning of a hull with numerical control adjustment for lifting, and belongs to the field of shipbuilding equipment. Background technique [0002] In the process of ship construction, the tire frame is an indispensable process equipment for the assembly and welding of hull segments, and it is the shape membrane 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 my country, most shipyards use fulcrum angle steel tire frames. In order to meet the requirements of specific segmented surface line types, this special tire frame needs to weld and cut steel fulcrums, which inevitably causes waste of steel. Under the condition of...
