Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method, apparatus, electronic device, and storage medium for processing ship outer plating. Background Technology

[0002] Currently, shipyards generally use Ship Product Design (SPD) systems to model and generate the parts needed for hull construction. Because hulls typically have a certain curvature, while internal parts are mostly straight structures, ship design software includes two relatively independent construction modules, one for the hull and the other for internal parts.

[0003] The hull, also known as the outer plating, is part of the SPD system, which includes an outer plating construction submodule specifically for generating models of the hull. Normally, curved hull plating requires CNC cutting into straight sections, followed by machining some or all of these sections into the desired curved shape. During machining, the plating undergoes varying degrees of shrinkage and deformation. Because various types of openings are needed on the hull plating, such as drainage plugs, it's difficult to control the precise location of these openings during machining. If openings are present, cracking may occur during machining. Therefore, the outer plating construction submodule in the SPD system does not include opening functionality. Openings on the hull plating are typically created by on-site construction workers in the later stages of hull construction, resulting in a longer shipbuilding cycle. Furthermore, opening openings generally require working at heights and involve risks of arc light and dust. Summary of the Invention

[0004] This invention provides a method for processing ship outer plating to solve the problems of long shipbuilding cycles, large workload of high-altitude operations, and high risk of arc light and dust damage caused by manual drilling in the process of processing ship outer plating.

[0005] In a first aspect, the present invention provides a method for treating the outer plating of a ship, comprising:

[0006] Based on the ship's outer plate unfolding file, multiple model files of outer plate parts are generated in the SPD system and stored in the parts library;

[0007] Based on the ship outer plate unfolding file, filter out the outer plate parts that meet the CNC drilling conditions and obtain the drilling information of the outer plate parts to be drilled.

[0008] For each of the outer plate parts to be drilled, the model file of the outer plate part to be drilled is converted into CAD file format and then imported into CAD.

[0009] Based on the hole information, the model file of the outer plate part to be drilled is modified in CAD to obtain the model file of the outer plate part with drilled holes.

[0010] Import the model file of the pre-drilled outer panel part into the parts library to replace the model file of the corresponding outer panel part to be drilled.

[0011] CNC cutting is performed based on the model files in the parts library.

[0012] In a second aspect, the present invention provides a ship outer plating processing apparatus, comprising:

[0013] The model file generation module is used to generate model files of multiple outer plate parts in the SPD system based on the ship outer plate unfolding file and store them in the parts library;

[0014] The module for determining outer plate parts to be drilled is used to select outer plate parts that meet the CNC drilling conditions from the outer plate parts based on the ship outer plate unfolding file, and to obtain the drilling information of the outer plate parts to be drilled.

[0015] The file conversion module is used to convert the model file of each outer plate part to be drilled into a CAD file format and then import it into CAD.

[0016] The model file hole-opening module is used to modify the model file of the outer plate part to be holed in CAD according to the hole-opening information, so as to obtain the model file of the outer plate part with hole already opened;

[0017] The import module is used to import the model file of the pre-drilled outer plate part into the parts library to replace the model file of the corresponding outer plate part to be drilled.

[0018] The CNC blanking module is used to perform CNC blanking based on the model files in the parts library.

[0019] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0020] At least one processor; and

[0021] A memory communicatively connected to the at least one processor; wherein,

[0022] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the ship outer plating processing method according to the first aspect of the present invention.

[0023] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the ship outer plating processing method described in the first aspect of the present invention.

[0024] This invention provides a method for processing ship outer plating. First, based on the ship outer plating unfolded file, multiple model files of outer plating parts are generated in an SPD system and stored in a parts library. Then, based on the ship outer plating unfolded file, outer plating parts that meet the CNC drilling conditions are selected from the outer plating parts to be drilled, and the drilling information of the outer plating parts to be drilled is obtained. For each outer plating part to be drilled, the model file of the outer plating part to be drilled is converted to CAD file format and imported into CAD. According to the drilling information, the model file of the outer plating part to be drilled is modified in CAD to obtain a model file of the drilled outer plating part. The model file of the drilled outer plating part is imported into the parts library to replace the corresponding model file of the outer plating part to be drilled. Finally, CNC blanking is performed based on the model file in the parts library. The outer plate parts that meet the conditions for CNC drilling are usually those that have been pre-drilled with CNC without affecting the subsequent processing effect and the quality of the plate. By importing the model file of the outer plate parts to be drilled into CAD for drilling operations, the drilling settings of the model file are completed. Then, CNC cutting can be performed based on the model file to obtain the drilled outer plate parts. For these outer plate parts, in the later stage of ship construction, there is no need for on-site construction personnel to drill holes, which can shorten the shipbuilding cycle, reduce the time spent working at height, and reduce the harm of arc light and dust.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] Example 1

[0037] Figure 1 This is a flowchart of a ship outer plating processing method provided in Embodiment 1 of the present invention. This embodiment is applicable to ship outer plating processing. The method can be executed by a ship outer plating processing device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method for treating the outer plating of this ship includes:

[0038] S101. Based on the ship's outer plate unfolding file, generate model files of multiple outer plate parts in the SPD system and store them in the parts library.

[0039] The SPD system is a software for 3D design centered on ship product data models. Through the SPD system, model files of multiple outer plating parts of a ship can be generated and stored in the parts library. In this step, the model files of multiple outer plating parts are generated in the SPD system based on the ship's outer plating unfolded file. Specifically, this includes: determining the name of each outer plating part according to the ship's outer plating unfolded file; defining a description file for each outer plating part in the SPD system, and generating a model file of the outer plating part based on the description file. Figure 2 This is a schematic diagram of a page for defining a description file for an outer panel component in an SPD system. The specific description file definition process is as follows: Figure 2 As shown, the description file definition includes section names, plate thickness information, allowance information, bevel information, part information, and plate seam information. The hull consists of multiple outer plate parts, each of which needs to be defined individually. After the description file is defined, the corresponding outer plate parts can be generated based on the description file.

[0040] Ship outer plating unfolding documents are specification documents that guide the production and manufacturing of outer plating parts. Specifically, they include unfolding drawings of the entire ship's outer plating, unfolding drawings of sections of outer plating, and may also include information on the openings of the outer plating, the type of outer plating (including flat plates and curved plates), etc.

[0041] S102. Based on the ship's outer plate unfolding file, filter out the outer plate parts that meet the CNC drilling conditions and obtain the drilling information of the outer plate parts to be drilled.

[0042] Outer panel parts that meet the requirements for CNC drilling usually refer to outer panel parts that have been pre-drilled with CNC without affecting the subsequent processing effect and the quality of the sheet material.

[0043] Ship hull plate unfolding documents can include the hull plate type, which includes flat plates and curved plates. Curved plates need to be CNC cut into straight sections first, and then some or all of them are processed into the required curved shape in a certain way. During the processing, the plates will shrink and deform to varying degrees. Because there are various types of openings on the hull plates, it is difficult to control the precise position of the openings during processing. If the openings exist, cracking may occur during processing. Therefore, existing SPD systems usually do not include the opening function, and curved plates are generally not CNC drilled.

[0044] In an optional embodiment, the outer plate part to be perforated only includes flat plates. Generally speaking, there are a certain number of flat plates of parallel mid-body structures at the bottom of the hull and on the side of the midship section of the hull.

[0045] Pre-drilling these outer panel parts with holes using CNC can reduce the workload and time required for manual hole drilling.

[0046] For flat plates, no curved surface processing is required in the later stages; therefore, flat plates are suitable for CNC drilling. Furthermore, for curved plates, considering that curved plates have different curvatures and surface areas, the larger the curvature and / or surface area, the greater the impact on the preset opening, processing effect, and plate quality during curvature processing, and vice versa. Therefore, this invention suggests that when the curvature and / or surface area of ​​a curved plate is small, it may still meet the CNC drilling requirements. Thus, curved plates can be further screened based on their curvature and / or surface area, and the standards for curvature and surface area used for screening can be preset. Generally, curved plates with larger curvature and / or surface areas are concentrated at the bow and stern of the hull, while those with smaller curvature and / or surface areas are concentrated in the midsection of the hull.

[0047] Therefore, in one optional embodiment, the outer plate part to be drilled includes a flat plate and may also include a curved plate. Compared to CNC drilling only on the flat plate, this embodiment performs CNC drilling on both the flat plate and the curved plate in advance, which can further reduce the workload and time of manual drilling.

[0048] S103. For each outer plate part to be drilled, convert the model file of the outer plate part to be drilled into CAD file format and then import it into CAD.

[0049] As previously described, the SPD system does not include hole-making functionality. Therefore, to modify the hole-making operation of the outer panel part to be made, the model file of the outer panel part to be made needs to be converted into CAD file format and then imported into CAD.

[0050] Optionally, after converting the model file of the outer panel part to be drilled into CAD file format and importing it into CAD, the process also includes deleting the model file of the outer panel part to be drilled in the SPD system. Since the outer panel part to be drilled will be imported into the SPD system again in a subsequent step, to avoid errors caused by duplicate outer panel parts, the exported model file of the outer panel part is deleted from the parts library of the SPD system after step S103.

[0051] S104. Modify the model file of the outer plate part to be perforated in CAD according to the hole information to obtain the model file of the outer plate part with perforation.

[0052] The opening information includes the opening location, opening diameter, and opening type.

[0053] Based on the hole information, modify the model file of the outer plate part to be drilled in CAD to obtain the model file of the drilled outer plate part. Specifically, this includes: obtaining the hole location information, hole diameter, and hole type based on the hole information; displaying the model file of the outer plate part to be drilled in the CAD drawing page; locating the working position in the model file of the outer plate part to be drilled based on the hole location information; drawing the hole at the working position based on the hole diameter and hole type; and saving the modified model file after drawing to obtain the model file of the drilled outer plate part.

[0054] It should be noted that in the SPD system, specific colored lines are usually used to represent specific types of structural lines. For example, if cyan lines are used to represent openings in the SPD system, then cyan lines should also be used to draw openings in CAD to ensure the consistency and usability of information attributes in the model file.

[0055] S105. Import the model file of the outer panel part with holes into the parts library to replace the model file of the corresponding outer panel part to be drilled.

[0056] Specifically, model files of perforated outer plate parts can be manually imported into the parts library to create TRAPS parts that the SPD system can automatically process, facilitating later processing. The imported parts library will then be a sub-parts library created manually. The sub-parts library page during import is shown below. Figure 3 As shown, Figure 3 This is a schematic diagram of a sub-parts library page that is manually entered into the SPD system.

[0057] S106. Perform CNC blanking based on the model file in the parts library.

[0058] After importing the model file of the perforated outer panel part into the parts library, the parts library contains both model files of the perforated outer panel part and the non-perforated outer panel part. CNC cutting is then performed based on the model files in the parts library, specifically including: generating nesting diagrams and cutting instructions based on the model files in the parts library; and implementing CNC cutting and perforation based on the nesting diagrams and cutting instructions. CNC drilling can be performed on the perforated outer panel part to obtain the solid form of the perforated outer panel part. The original non-perforated outer panel part generated by the SPD system is processed into a perforated outer panel part, and then, through nesting and cutting, the purpose of CNC drilling is achieved, reducing the time and workload of manual perforation.

[0059] In an optional embodiment, before performing CNC cutting based on model files in the parts library, the method further includes: determining whether there are model files with duplicate names in the parts library; if so, deleting the model files with duplicate names generated by the SPD system from the parts library.

[0060] The SPD system can have two sub-part libraries: one automatically generated by the SPD system and the other manually added. If model files with the same part name exist in both sub-part libraries, one of the model files may be discarded, potentially invalidating the model file of an outer panel part with holes, leading to inaccurate hole modification. Therefore, it is crucial to ensure the uniqueness of part names in the model files of both sub-part libraries. Failure to check and address this step may result in subsequent nesting operations using parts without holes generated by the original system, causing hole modification failures and material waste.

[0061] Figure 4 This is a schematic diagram of a sub-part library page for a part automatically generated in an SPD system. For example... Figure 4 As shown, the page of this sub-parts library has a delete button, which means it has a deletion function that can delete parts (model files) with the same part name as parts manually added to the sub-parts library.

[0062] This invention provides a method for processing ship outer plating. First, based on the ship outer plating unfolded file, multiple model files of outer plating parts are generated in an SPD system and stored in a parts library. Then, based on the ship outer plating unfolded file, outer plating parts that meet the CNC drilling conditions are selected from the outer plating parts to be drilled, and the drilling information of the outer plating parts to be drilled is obtained. For each outer plating part to be drilled, the model file of the outer plating part to be drilled is converted to CAD file format and imported into CAD. According to the drilling information, the model file of the outer plating part to be drilled is modified in CAD to obtain a model file of the drilled outer plating part. The model file of the drilled outer plating part is imported into the parts library to replace the corresponding model file of the outer plating part to be drilled. Finally, CNC blanking is performed based on the model file in the parts library. The outer plate parts that meet the conditions for CNC drilling are usually those that have been pre-drilled with CNC without affecting the subsequent processing effect and the quality of the plate. By importing the model file of the outer plate parts to be drilled into CAD for drilling operations, the drilling settings of the model file are completed. Then, CNC cutting can be performed based on the model file to obtain the drilled outer plate parts. For these outer plate parts, in the later stage of ship construction, there is no need for on-site construction personnel to drill holes, which can shorten the shipbuilding cycle, reduce the time spent working at height, and reduce the harm of arc light and dust.

[0063] Example 2

[0064] Figure 5 This is a flowchart of a method for processing ship outer plating according to Embodiment 2 of the present invention. This embodiment of the present invention is an optimization based on Embodiment 1 described above, such as... Figure 5 As shown, the method for treating the outer plating of this ship includes:

[0065] S501. Based on the ship's outer plate unfolding file, generate model files of multiple outer plate parts in the SPD system and store them in the parts library.

[0066] The ship's outer plating unfolding documents include unfolding diagrams of multiple outer plating sections.

[0067] S502. For each segment of the outer plate unfolded drawing, identify the flat edge line and boundary line in the segment of the outer plate unfolded drawing.

[0068] The segmented outer panel unfolded drawing includes flat edge lines and transverse boundary lines. The flat edge lines distinguish between curved surfaces and planes; surfaces are above the flat edge lines, and planes are below them. The transverse boundary lines define the transverse boundaries of the outer panel components. The segmented outer panel unfolded drawing also includes longitudinal seams, which are the seams between adjacent outer panel components, i.e., the longitudinal boundaries of each outer panel component. The longitudinal seams and transverse boundary lines define the areas of each outer panel component. Therefore, in this embodiment, the boundary lines can include both transverse boundary lines and longitudinal seams.

[0069] Figure 6 This is a schematic diagram of the unfolded shape of a segmented outer plate, such as... Figure 6 As shown, the segmented outer panel unfolded drawing includes flat edge lines LP and transverse boundary lines Lb1 and Lb2, as well as multiple longitudinal seams. The longitudinal seams and transverse boundary lines Lb1 and Lb2 enclose the various outer panel components. For example, in... Figure 6 In the diagram, longitudinal seam lines 209 and 207, along with transverse boundary lines Lb1 and Lb2, form outer panel component A1. Longitudinal seam lines 207 and 204, along with transverse boundary lines Lb1 and Lb2, form outer panel component A2. In addition, there are outer panel components A3 and A4, which will not be listed here.

[0070] S503. The area enclosed by the flat edge line and the boundary line is designated as the flat plate area.

[0071] Boundary lines can include transverse boundary lines and longitudinal seams. The boundary line in the longitudinal direction is the longitudinal seam, and there are multiple longitudinal seams. Therefore, in this embodiment, the largest area enclosed by the flat edge line, transverse boundary line, and longitudinal seam can be considered as the flat plate area, such as... Figure 6 As shown, the area enclosed by the flat edge line LP and the transverse boundary lines Lb1 and Lb2 is a flat plate region. Each region has a curved surface above the flat edge line LP and a flat surface below it. Figure 6 In the above, assuming there are no other longitudinal seams below the 201 longitudinal seam, the area enclosed by the flat edge line LP, the transverse boundary lines Lb1 and Lb2, and the 201 longitudinal seam is a flat area.

[0072] S504. Based on the planar overlap relationship between the outer panel parts and the flat plate area, select the outer panel parts that meet the CNC drilling conditions from the outer panel parts.

[0073] like Figure 6 As shown, the area above the flat edge line LP is curved, and the area below it is flat. Therefore, for outer panel parts A1 and A2, part of them lies above the flat edge line LP, and part of them lies below the flat edge line LP. Thus, the surface areas of outer panel parts A1 and A2 are divided into curved surfaces and flat surfaces, making them curved panels. For outer panel parts A3 and A4, both of them lie below the flat edge line LP. Therefore, the surface areas of outer panel parts A3 and A4 are both flat, making them flat panels. It can be seen that the type of outer panel part can be determined by the planar overlap relationship between the outer panel part and the flat plate area.

[0074] In an optional embodiment, if the outer plate part to be drilled only includes a flat plate, then the outer plate type of the outer plate part can be determined based on the planar overlap relationship between the outer plate part and the flat plate area, and the outer plate part with the outer plate type of flat plate is regarded as the outer plate part to be drilled that meets the CNC drilling conditions.

[0075] In an optional embodiment, based on the planar overlap relationship between the flat plate region and the outer plate parts, outer plate parts that meet the CNC drilling conditions are selected from the outer plate parts, including: selecting outer plate parts that have a planar overlap relationship with the flat plate region as candidate outer plate parts; determining a straight sub-flat plate region in each candidate outer plate part based on the planar overlap relationship; calculating the area ratio of the sub-flat plate region in each candidate outer plate part; determining whether the area ratio is greater than a preset ratio threshold; if so, selecting the candidate outer plate part as a candidate outer plate part that meets the CNC drilling conditions; if not, determining that the candidate outer plate part does not meet the CNC drilling conditions.

[0076] For flat plates, no curved surface processing is required in the later stages; therefore, flat plates are suitable outer plate parts for CNC drilling. For curved plates, considering that curved plates have different surface areas, the larger the surface area, the greater the impact on the preset opening, processing effect, and plate quality during the curvature processing, and vice versa. Therefore, this invention believes that when the surface area of ​​a curved plate is small, it may still meet the CNC drilling requirements. Thus, curved plates can be further screened based on their surface area, and the standard for the surface area used for screening can be preset. Therefore, in this embodiment, the sub-flat plate area in each outer panel part is determined based on the planar overlap relationship between the outer panel part and the flat plate area. Then, the area of ​​the sub-flat plate area in the outer panel part is determined as a percentage of the total area of ​​the outer panel part to determine whether the CNC drilling conditions are met. The outer panel part to be drilled includes a flat plate and may also include a curved plate. Compared with CNC drilling only on the flat plate, this embodiment performs CNC drilling on the flat plate and the curved plate in advance, which can further reduce the workload and time of manual drilling.

[0077] Optionally, the preset ratio threshold is 75%-80%, which can be set according to actual needs. Figure 6 In the middle, the curved plate includes outer plate parts A1 and A2. Outer plate part A1, from Figure 6 As can be seen, the sub-flat area overlapping with the flat plate area accounts for less than 75% of the total area of ​​outer plate part A1. Therefore, outer plate part A1 cannot be used as an outer plate part to be drilled. For outer plate part A2, the sub-flat area overlapping with the flat plate area accounts for more than 75% of the total area of ​​outer plate part A1. Therefore, outer plate part A2 can be used as an outer plate part to be drilled. Outer plate parts A3 and A4 are flat plates. They can be used as outer plate parts to be drilled based on their outer plate type, or based on the proportion of the sub-flat plate area.

[0078] S505. Obtain the hole information of the outer plate part to be drilled from the segmented outer plate unfolded drawing.

[0079] S506. For each outer panel part to be drilled, convert the model file of the outer panel part to be drilled into CAD file format and then import it into CAD.

[0080] S507. Modify the model file of the outer plate part to be perforated in CAD according to the hole information to obtain the model file of the outer plate part with perforation.

[0081] S508. Import the model file of the outer panel part with holes into the parts library to replace the model file of the corresponding outer panel part to be drilled.

[0082] S509. Perform CNC blanking based on the model file in the parts library.

[0083] S501, S506-S509 are similar to S101, S103-S506 in Embodiment 1, respectively. For details, please refer to the relevant description in Embodiment 1, which will not be repeated here.

[0084] In this embodiment, when determining the outer panel part to be drilled, for each segmented outer panel unfolded drawing, the flat edge line and the transverse boundary line are identified in the segmented outer panel unfolded drawing; the area enclosed by the flat edge line and the transverse boundary line is taken as the flat plate area; based on the planar overlap relationship between the flat plate area and the outer panel part, the outer panel part is selected as the outer panel part to be drilled that meets the CNC drilling conditions; the drilling information of the outer panel part to be drilled is obtained from the segmented outer panel unfolded drawing. Based on the planar overlap relationship between the flat plate area and the outer panel part, the outer panel type of the outer panel part can be determined. In one way, the flat plate can be directly used as the part to be drilled; in another way, the outer panel part can be further screened based on the outer panel type and the size of the overlap area (the proportion of the sub-flat plate area to the total area of ​​the outer panel part), so that some of the panels can also be used as CNC drilling objects, which can further reduce the workload and time of manual drilling.
