Description

Technical Field

[0001] The present invention belongs to the technical field of firearm design, and in particular relates to a cross-regional collaborative design method and system for firearm technology based on model definition. Background Art

[0002] Process refers to the technology and engineering involved in converting product design drawings into actual products. The core content of process design is to formulate the production process of the workshop, explain the production process, specifications and quantity of the main production equipment and auxiliary equipment; calculate the demand for raw materials and semi-finished products in the factory, clarify the production tasks of each workshop and the cooperation between them, formulate production and operation plans, product quality inspection, product supply and marketing ordering systems, formulate labor and production organization and work systems, etc.

[0003] A typical model of product development and production in my country is completed by the joint cooperation of research institutes and factories in two or more locations. The research institute is responsible for product design. After the design is completed, the full set of design drawings will be packaged and sent to the factory. The factory is responsible for the subsequent manufacturing and production of the product based on the design drawings. The research institute and the factory are different units, and the product design software they use may be inconsistent. The research institute focuses on R&D and design, and has some trial production and verification conditions; the factory focuses on production and manufacturing, and also has some design capabilities. Therefore, the process software of the research institute is often positioned in the function of rapid process design, while the process software of the factory must take into account the reception of upstream design data, the export of process BOM data for the downstream workshop APS / MES system, the output of two-dimensional process cards and other functions, and is more inclined to the manufacturing management system. Therefore, the process software is mostly different, which often brings problems such as data heterogeneity between the two units.

[0004] In the light weapons industry, when the research institute develops new firearms products, the cooperating factories will also participate in the joint design of the institute and the factory, and the design data formed is a three-dimensional model; when the product is manufactured and produced, the research institute will go to the factory to follow the processing and negotiate to solve the technical problems encountered on site. During the development of new firearms products, trial production and processing verification will be carried out, and new processes are often introduced. The specific scenario is that in the research institute, after the three-dimensional model of the product parts is designed, the three-dimensional process design software is used to compile the trial production process or new process based on the three-dimensional model, and the trial production of the parts and product testing are carried out; after the sample undergoes various professional tests, the design engineer optimizes the design model according to the test results. When the product enters the manufacturing and production stage, the research institute stores the product three-dimensional model and process file as two independent files and transmits them to the factory. The factory saves the product three-dimensional design model to the manufacturing management system, and then carries out process procedure design based on the system. After the research institute completes the product design and finalizes the version, it sends the product three-dimensional model and other design data to the factory. This is the basic business of design-manufacturing between the institute and the factory, and the network transmission and management conditions are already available. Sending process files and maintaining association and version consistency with the product 3D model increases data transmission requirements and difficulty. The two types of data are weakly associated, which can easily cause data relationship disorder or loss after transmission. After the production unit saves the 3D model to the local system, data incompatibility often occurs due to the difference between the process design software and the research institute, and the heterogeneous data. It is necessary to manually enter the trial production process / new process content in the process software, which weakens the process collaboration effect, reduces the quality of process collaborative design, increases the workload of the production unit's process personnel, and increases time and labor costs. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a cross-regional collaborative design method and system for firearms technology based on model definition.

[0006] The first aspect of the present invention discloses a cross-regional collaborative design method for firearms technology based on model definition, the method comprising:

[0019] S16, in the trial-production process models that have been sorted, the constructed trial-production step models are arranged in a tree structure.

[0020] Step S1 also includes:

[0021] S17, converting the modified trial production process content into a modified trial production process array, and comparing the modified trial production process array with the number and attribute values ​​of the trial production process model; if the number of the modified trial production process array is increased or deleted, the trial production process model is also increased or deleted accordingly; if the content of the modified trial production process array is changed, the corresponding attributes of the trial production process model are changed;

[0022] S18, converting the modified trial production step content into a modified trial production step array, and comparing the modified trial production step array with the number and attribute values ​​of the trial production step model; if the number of the modified trial production step array is increased or deleted, the trial production step model is also increased or deleted accordingly; if the content of the modified trial production step array is changed, the corresponding attributes of the trial production step model are changed.

[0023] Step S3 specifically includes:

[0024] S31, obtaining the process content in the parsed three-dimensional model structure file and modifying it, converting it into a process array of the batch production process, and storing the content in the process array of the batch production process into the attributes of the process model of the batch production process;

[0034] In summary, the solution proposed by the present invention has the following technical effects:

[0035] 1. The firearms process is defined by the model. During the remote process collaborative design, there is no need to transmit two independent files, the 3D design model and the process specification. Instead, the 3D model containing the process information needs to be sent to the manufacturer as the 3D model was sent before. The association between the process data and the 3D design model ensures data consistency.

[0036] 2. Use 3D model structure to organize and manage product process information in a documented form.

Whether viewing and editing 3D design models or conducting various typical process designs, it is familiar, simple and convenient to operate, and improves work efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first image may be referred to as a second image, and similarly, a second image may be referred to as a first image without departing from the scope of this application. Both the first image and the second image are images, but they are not the same image.

[0046] See also Figure 1 According to an embodiment of the present invention, in a first aspect, a cross-regional collaborative design method for firearms technology based on model definition is disclosed, the method comprising:

[0047] S1, defining the product process information as a three-dimensional model structure file; wherein the three-dimensional model structure file includes a top-level structure, a first-level component, and a second-level component; the top-level structure is a part model or an assembly model, the first-level component is a trial production process model containing process information, and the second-level component is a trial production step model containing process step information;

[0048] In step S1, the construction of the trial production process model includes:

[0049] S11, converting the trial production process content into a trial production process array, and determining the content of the trial production process array according to the process type;

[0050] S12, creating the same number of trial production process model files according to the number of trial production process arrays, and storing the contents of the trial production process arrays into the attributes of the trial production process model files to complete the construction of the trial production process model.

[0051] Specifically, the preparation and storage of the trial production process content, in NX software, the trial production process process content written in the design phase is defined as an array, GX = {gx1, gx2, ..., gxi, ..., gxn}, where gxi is defined as the attribute of the set GX, and the value corresponding to gxi is defined as the characteristic value. The array content is determined according to the process type, which includes assembly process, machining process, heat treatment process, etc.; for example, if the process type is machining process, GX = {component number | process number | process name | key process | process type | remarks}, the component number is JTT_proc_01, the process number is 1, the process name is blanking, the key process is the key process, the process type is the picking process, and the remarks are empty. In the part model, the process models are arranged in a tree structure, the part model containing the three-dimensional design data is the parent item, and the process model containing the three-dimensional process data and process process attribute information is the child item.

[0052] In step S1, the construction of the trial production step model includes:

[0053] S13, converting the trial production step content into a trial production step array;

[0054] S14, creating trial-manufacturing step model files with the same number of trial-manufacturing step arrays according to the number of trial-manufacturing step arrays, and storing the contents of the trial-manufacturing step arrays into the properties of the trial-manufacturing step model files to complete the construction of the trial-manufacturing step model.

[0055] Specifically, the preparation and storage of the trial-manufacturing step contents converts the trial-manufacturing step contents written in the design phase into an array, GB = {gb1, gb2, ..., gbi, ..., gbn}, where gbi is defined as an attribute of the set GB, and the value corresponding to gbi is defined as a characteristic value. For example, GB = {component number | process step number | process step name | technical requirements | tool | gauge | cutting depth | feed | number of revolutions | inspection frequency | working hours}, the component number is JTT_proc_02_proc_03, the process step number is 3, the process step name is rough milling of spiral surface, the technical requirement is to ensure sufficient allowance, the tool is an end mill, the gauge is empty, the cutting depth is 2, the feed is 0.1, the number of revolutions is 3000, the inspection frequency is empty, and the working hours is 1; create the same number of trial production step models according to the number of arrays, and store the contents of the trial production step array in the properties of the trial production step model; in the trial production process model, the trial production step models are arranged in a tree structure, the trial production process model is the parent item, and all trial production step models are child items.

[0056] Step S1 also includes:

[0057] S17, converting the modified trial production process content into a modified trial production process array, and comparing the modified trial production process array with the number and attribute values ​​of the trial production process model; if the number of the modified trial production process array is increased or deleted, the trial production process model is also increased or deleted accordingly; if the content of the modified trial production process array is changed, the corresponding attributes of the trial production process model are changed;

[0058] S18, converting the modified trial production step content into a modified trial production step array, and comparing the modified trial production step array with the number and attribute values ​​of the trial production step model; if the number of the modified trial production step array is increased or deleted, the trial production step model is also increased or deleted accordingly; if the content of the modified trial production step array is changed, the corresponding attributes of the trial production step model are changed.

[0059] In this step, the 3D design model attribute function is used to organize, store and manage the process specification information, and the process specification data is defined based on the 3D model. The product process information is organized and managed in the form of 3D model structure documentation. The top-level structure is the part or assembly model, the first-level component is the model containing the process information, and the second-level component is the model containing the process step information. Compared with the two-dimensional process card, the process structure is clear.

[0060] S2, based on the data collaborative release strategy between institutes and factories, transmit the 3D model structure file to the factory end across regions;

[0061] In this step, the existing product design data remote distribution function of the factory is fully utilized during cross-regional process collaboration. The process specification information attached to the 3D model data can be sent at the same time as the 3D model data is transmitted. During remote process collaborative design, there is no need to transmit two independent files, the 3D design model and the process specification. Only the 3D model containing the process information needs to be sent to the manufacturer as the 3D model was sent before. The association between the process data and the 3D design model ensures data consistency.

[0062] S3 reads the 3D model structure file at the factory end, parses the process content and work step content in the 3D model structure file, and edits and modifies the parsing results according to the production site conditions, thereby realizing cross-regional collaborative design of firearms technology.

[0063] Step S3 specifically includes:

[0064] S31, obtaining the process content in the parsed three-dimensional model structure file and modifying it, converting it into a process array of the batch production process, and storing the content in the process array of the batch production process into the attributes of the process model of the batch production process;

[0065] S32, obtaining the work step content in the parsed three-dimensional model structure file, modifying it, converting it into a work step array of the batch production process, and storing the content in the work step array of the batch production process into the attributes of the work step model of the batch production process;

[0066] S33, arranging the constructed process step models of each batch production process in a tree structure in the process model of the batch production process to obtain a two-dimensional process model;

[0067] S34, packaging the two-dimensional process model into an XML file according to the structural hierarchy of the process steps, and sending it to the production and manufacturing system.

[0068] Specifically, see Figure 2 , manufacturer's process collaborative editing and storage.

[0069] Editing the content of the production process: the manufacturer checks or edits the trial production process sent by the design unit, modifies the content of the trial production process into the content of the production process, converts the content of the production process into an array (same as step S11), and compares it with the number and attribute values ​​of the tree structure process model. If the number of arrays is increased or deleted, the structure tree process model is also increased or deleted accordingly; if the content of the array is changed, the corresponding attributes of the structure tree process model are changed;

[0070] Edit the content of the production step, modify the trial production step content to the production step content, convert the modified production step content into an array (same as S13 in step 1), and compare it with the number and attribute values ​​of the tree structure step model. If the number of the step array is increased or deleted, the structure tree step model is also increased or deleted accordingly; if the content of the array is changed, the corresponding attributes of the structure tree step model are changed;

[0071] Teamcenter production process is stored in the production and manufacturing system (manufacturers reuse process), and the production process and process step content outside the production and manufacturing system in the computer are converted into arrays and saved in an xml file named after the model. The array format is as follows: ZJ = {zj1, zj2, ..., zji, ..., zjn}, where zji is defined as the attribute of the set ZJ, and the value corresponding to zji is defined as the characteristic value; ZJ = {component number|process number|process name|key process|process type|remarks|component number|process step number|process step name|technical requirements|tool|gauge|cutting depth|feed|rotation|inspection frequency|working hours}. In the integrated environment of NX design software and TeamCenter production and manufacturing system, the array in the xml file named after the model is read, and the same number of process models are created in the production and manufacturing system according to the number of arrays. The process model object type in the production and manufacturing system is determined according to the process type (such as blanking, machining, heat treatment, etc.), and the array content is generated and stored in the attribute parameter information of the process model of the production and manufacturing system.

[0072] In this step, based on the data integration function of the factory's process design software and manufacturing management system, the manufacturer only needs to save the 3D model containing process specification information into the manufacturing management system to reuse heterogeneous processes. The manufacturer's process personnel save the assembly model containing the 3D model and process into the production and manufacturing management system, view the model and process in the system, and reuse the trial production process / new process using the firearms 2D process design software of the manufacturing management system. The production process can be quickly designed, and the process can be output according to the factory's original 2D process card template specifications, which improves work efficiency and saves labor costs.

[0073] The second aspect of the present invention discloses a cross-regional collaborative design system for firearms technology based on model definition, the system comprising:

[0074] The first processing module is configured to define the product process information as a three-dimensional model structure file; wherein the three-dimensional model structure file includes a top-level structure, a first-level component, and a second-level component; the top-level structure is a part model or an assembly model, the first-level component is a trial production process model containing process information, and the second-level component is a trial production step model containing process step information;

[0075] The second processing module is configured to transmit the three-dimensional model structure file to the factory end across regions based on the collaborative data distribution between the institute and the factory;

[0076] The third processing module is configured to read the three-dimensional model structure file at the factory end, parse the process content and work step content in the three-dimensional model structure file, and edit and modify the parsing results according to the production site conditions, thereby realizing cross-regional collaborative design of firearms technology.

[0077] For details, please refer to the cross-regional collaborative design system architecture of the factory's firearms technology. Figure 3The process design software of the institute (intelligent rapid design software for typical firearm processes) is newly developed on the basis of Siemens NX CAD software. It has functions such as example-based firearm process route planning, process process compilation, process step process compilation, process parameter reasoning, process simulation and optimization, etc. It can design typical processes such as firearm machining, heat treatment and assembly, and the generated process procedures are defined in the corresponding three-dimensional model. The factory process design software (firearm two-dimensional process design software) was developed based on the Siemens Teamcenter production and manufacturing management system in the early years. It has functions such as process route planning, process information compilation, process step information compilation, process information filling, process basic resource selection, and two-dimensional process card formatting generation. The function of data collaborative distribution between the institute and the factory is realized based on two PDM (product data management) systems. Based on the above technical conditions, the present invention creates model-based process data definition, three-dimensional process data analysis and integration methods, and develops an integrated interface function, thereby providing a cross-regional collaborative design method and means for firearm processes based on model definition. After the trial production process / new process of the research institute is distributed to the factory along with the 3D model, a new process is first created in the factory's firearms 2D process software, and then the 3D process to be referenced is read in. Through process specification analysis, a 2D process specification is generated, and edited and modified according to the production site conditions, thereby realizing the reuse of the trial production process / new process.

The electronic device includes a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the steps of any one of the cross-regional collaborative design methods for firearms processes based on model definition in the first aspect of the present disclosure are implemented.

Among them, the processor of the electronic device is used to provide computing and control capabilities. The memory of the electronic device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium.
