[0024] Embodiment 1 A method for compiling the process specification for aircraft component assembly connection. First, according to the process requirements and process flow of aircraft component assembly connection, construct the process specification template for aircraft component assembly connection and the process parameter library for aircraft component assembly connection; then, according to the key conditions affecting the processes of the aircraft component assembly connection process specification template, obtain the connection process parameters; finally, according to the assembly digital model information, transfer the connection process parameters to fill the aircraft component assembly connection process specification template, and complete the compilation of the aircraft component assembly connection process specification.

[0025] Adopting this implementation manner, according to the process requirements and process flow of aircraft component assembly connection, design the process specification template for aircraft component assembly connection and the process parameter library for aircraft component assembly connection, analyze the key conditions affecting the processes of the aircraft component assembly connection process specification template, obtain the connection process parameters, and realize that after obtaining the assembly digital model information, quickly transfer the connection process parameters, certification requirements and other relevant parameters to complete the rapid compilation of the aircraft component assembly connection process specification, aiming to achieve the efficient and accurate design of the aircraft component assembly connection process by constructing a comprehensive knowledge and rule library.

[0026] Refer to Figure 1 , in an alternative implementation manner, it includes the following steps: Step S101: Construct a knowledge- and rule-based process parameter library for aircraft component assembly connection, specifically construct a knowledge- and rule-based process parameter library for aircraft component assembly connection, establish the association relationship between the connection process parameters and the process parameter library, and set two data interaction modes of unified data push and active retrieval to meet the requirements in different scenarios; Step S102: Define the aircraft component assembly elements that affect the aircraft component assembly connection process flow, specifically clarify which elements will affect the aircraft component assembly connection process flow; Step S103: Establish the association relationship between the assembly elements of aircraft components and the assembly connection process flow of aircraft components, construct the assembly connection process flow of aircraft components, and generate the template of the assembly connection process specification for aircraft components; Step S104: Construct the judgment logic of the assembly elements of aircraft components that affect the assembly connection process flow of aircraft components; Step S105: Complete the compilation of the assembly connection process specification for aircraft components according to the assembly connection process parameter library, the template of the assembly connection process specification for aircraft components, and the judgment logic.

[0027] Embodiment 2 This embodiment is further optimized on the basis of the above Embodiment 1. In this embodiment, the method for constructing the assembly connection process parameter library of aircraft components includes: Construct the multi-dimensional input / output data form of the assembly connection process parameter library of aircraft components according to the data retrieval scheme, data source, and logical rules of the process parameters used in the aircraft component assembly process; Generate the assembly connection process knowledge and assembly connection process rules according to the assembly connection process experience and assembly connection process requirements in the aircraft component assembly connection process; According to the key fields in the assembly connection process parameter library of aircraft components, associate the data tables in the assembly connection process parameter library of aircraft components to construct the data association relationship between the assembly connection process parameter libraries of aircraft components; Establish the assembly connection process parameter library of aircraft components including the assembly connection process parameter library of aircraft component processes and the general assembly connection process parameter library of aircraft components according to the data association relationship, data form, assembly connection process knowledge, and assembly connection process rules; Construct a parameter acquisition mode for uniformly pushing data for the assembly connection process parameter library of aircraft component processes, and construct a parameter acquisition mode for actively retrieving data for the general assembly connection process parameter library.

[0028] Specifically, according to the data retrieval scheme, data sources, and logical rules of the process parameters used in the component assembly process, a multi-dimensional input / output data form of the aircraft component assembly connection process parameter library is constructed, CLASS1{IN1; OUT1}, CLASS2{IN1, IN2, ……INn; OUT1}, CLASS3{IN1; OUT1, OUT2, OUT3, ……OUTn}, CLASS4{IN1, IN2, IN3, ……INn; OUT1, OUT2, OUT3, ……OUTn}; where CLASS1 represents the program unified identification that supports the initial data; CLASS2 represents that after supporting multi-condition input, a unique result is logically deduced; CLASS3 represents the multi-dimensional definition after data input, and the output results of different dimensions can be applied to different scenarios; CLASS4 represents that after supporting multi-condition input, the logically deduced results of different dimensions can be applied to different scenarios.

[0029] Based on the process experience and process requirements of the aircraft component assembly connection process, induction and reasoning are carried out to form process knowledge and process rules. In order to reduce data redundancy and increase the coherence between data, 9 aircraft component assembly connection process parameter libraries are constructed, including 6 aircraft component assembly connection process parameter libraries for processes and 3 aircraft component assembly connection general process parameter libraries; the 6 aircraft component assembly connection process parameter libraries for processes are: material library, standard part library, recycled standard part type library, constant force tool library, connecting part hole diameter library, and bonding bracket quality inspection library; the 3 aircraft component assembly connection general process parameter libraries are: standard operation procedure library, certified information library, and inspection type library.

[0030] See Figure 2 , through the key fields in the data table, the data tables of the parameter libraries are associated, the data association relationship between the connection parameter libraries is formulated, and two parameter acquisition modes of unified push data and active retrieval data are constructed; Parameter acquisition mode for actively retrieving data: The process parameters of the process are related to the aircraft component assembly connection process specification template and assembly process where it is located. For different assembly processes, the acquisition logic rules of the process parameters are different. According to the aircraft component assembly connection process specification template and its corresponding process, through the replacement symbols in the template, the information of the aircraft component assembly connection process parameter library is actively retrieved for each process, and through the logical matching and reasoning judgment between the aircraft component assembly connection process parameter libraries, the obtained parameter results are placed in the replacement symbol position of the process parameters; Material library {Input: standard part drawing number; Output: connecting part sandwich parts, sandwich part material grade, number of connecting parts, drilling area type}; Standard part library {Input: standard part drawing number; Output: drawing number feature, drawing number diameter feature, strength characteristic}; Recycled standard part type library {Input: drawing number features; Output: recycled content}; Connector hole diameter library {Input: drawing number diameter features; Output: drawing number diameter code}; Fixed force tool library {Input: standard part drawing number, strength characteristics, drawing number diameter code; Output: fixed force tool drawing number, fixed force requirement}; Bonding pallet quality inspection library {Input: drawing number diameter features, drawing number diameter code; Output: inspection requirements}.

[0031] Parameter acquisition mode for unified push data: To avoid repeated retrieval of process parameters during the preparation of process specifications, a set of parameter libraries and matching logic rules are established uniformly. According to the aircraft component assembly connection process specification template and its corresponding processes, the process parameter library uniformly pushes general process parameter information to the processes and places it in the parameter positions corresponding to the processes; Standard operation procedure library {Input: aircraft component assembly connection process specification template name, process name, drawing number features...; Output: standard operation procedure number, standard operation procedure name}; Certification information library {Input: aircraft component assembly connection process specification template name, process name, drawing number features...; Output: certification code}; Inspection type library {Input: aircraft component assembly connection process specification template name, process name, drawing number features...; Output: inspection type}.

[0032] According to the structural form of the drilling process parameter library and the designed input / output function mode, establish the association relationship between the component assembly drilling process parameters and the eight drilling process parameter libraries.

[0033] In this embodiment, the method for constructing the aircraft component assembly connection process specification template includes: Define the aircraft component assembly elements that affect the aircraft component assembly connection process flow; Establish the association relationship between the aircraft component assembly elements and the aircraft component assembly connection process flow and construct the aircraft component assembly connection process flow; According to the aircraft component assembly connection process flow and the standard process library, establish the aircraft component assembly connection process specification template corresponding to the assembly scenario.

[0034] Specifically, the method of defining the aircraft component assembly elements that affect the aircraft component assembly connection process flow and clearly indicating which elements will affect the aircraft component assembly connection process flow includes: According to the assembly design requirements and process requirements of aircraft components, defining whether the connecting piece is a double-threaded bolt, whether the connecting piece is a rivet, whether the connecting piece is an adhesive retainer nut / screw, whether the connecting piece is a bolt / screw, whether the connecting piece is a constant-force high-lock, whether the connecting piece is a nut-shearing high-lock, and whether the connecting piece is a blind rivet are 7 aircraft component assembly elements that affect the entire aircraft component assembly connection process flow.

[0035] A method for establishing the correlation between aircraft component assembly elements and the aircraft component assembly connection process flow, constructing the aircraft component assembly connection process flow, and generating the aircraft component assembly connection process specification template includes: Analyze one by one the influence of the 7 aircraft component assembly elements, namely whether the connecting piece is a double-threaded bolt, whether the connecting piece is a rivet, whether the connecting piece is an adhesive retainer nut / screw, whether the connecting piece is a bolt / screw, whether the connecting piece is a constant-force high-lock, whether the connecting piece is a nut-shearing high-lock, and whether the connecting piece is a blind rivet, on the aircraft component assembly connection process flow, and construct the process flow; Establish the correlation between "whether the connecting piece is a double-threaded bolt" and the aircraft component assembly connection process flow, and design the connection process flow for the connecting piece being a double-threaded bolt: For the connection of double-threaded bolt standard parts, after completing the hole-making operations such as drilling and countersinking, according to the design digital model, first install the bushing on the part with countersunk holes, then rivet the retainer nut for the double-threaded bolt on the other laminated parts, and finally install and fix all the laminated parts through the double-threaded bolt to complete all the work of the double-threaded bolt connection.

[0036] Establish the correlation between "whether the connecting piece is a rivet" and the aircraft component assembly connection process flow, and design the connection process flow for the connecting piece being a rivet: For the connection of rivets, after completing the hole-making operations such as drilling and countersinking, according to the design digital model, rivet and fix all the laminated parts through the rivets to complete all the work of the rivet connection.

[0037] Establish the correlation between "whether the connecting piece is an adhesive retainer nut / screw" and the aircraft component assembly connection process flow, and design the connection process flow for the connecting piece being an adhesive retainer nut / screw: For the connection of adhesive retainer nut / screws, after completing the hole-making operations such as drilling and countersinking, according to the design digital model, perform grinding, cleaning, and pasting on the position where the connecting piece is connected to the skeleton. After pasting, perform anti-corrosion protection on the redundant grinding area before pasting, that is, complete the connection work of the adhesive retainer nut / screw.

[0038] Establish the correlation between "whether the connecting piece is a bolt / screw" and the aircraft component assembly connection process flow, and design the connection process flow for the connecting piece being a bolt / screw: For the connection of bolts / screws, after completing the hole-making operations such as drilling and countersinking, according to the design digital model, all stacked parts are bolted or screwed together to complete all the work of bolt / screw connection.

[0039] Establish the correlation between "whether the connecting piece is a high-lock with fixed force" and the aircraft component assembly connection process flow, and design the connection process flow for the connecting piece being a high-lock with fixed force: For the connection of high-locks with fixed force, after completing the hole-making operations such as drilling and countersinking, first check tools such as the fixed-force wrench for installation. After passing the inspection, according to the design digital model, all stacked parts are installed and fixed with high-lock bolts and high-lock nuts to complete all the work of high-lock connection with fixed force.

[0040] The method of establishing the correlation between "whether the connecting piece is a high-lock with nut-breaking cap" and the aircraft component assembly connection process flow and designing the connection process flow for the connecting piece being a high-lock with nut-breaking cap includes: For the connection of high-locks with nut-breaking cap, after completing the hole-making operations such as drilling and countersinking, according to the design digital model, all stacked parts are installed and fixed with high-lock bolts and high-lock nuts. After installation, the head of the high-lock nut is separated and broken from the main body of the nut. After completing all the work of high-lock connection with fixed force, it is necessary to conduct a recovery inspection on the broken cap of the high-lock nut.

[0041] Establish the correlation between "whether the connecting piece is a blind rivet" and the aircraft component assembly connection process flow, and design the connection process flow for the connecting piece being a blind rivet: For the connection of blind rivets, similar to the connection of high-locks with nut-breaking cap, after installation, it is also necessary to conduct a recovery inspection on the broken cap of the blind rivet.

[0042] See Figure 3 , combining all the above connection processes, set the initial cleaning, gluing, as well as the final foreign object inspection and inspection processes as common default processes, and finally form a complete aircraft component assembly connection process specification template to construct a complete aircraft component assembly connection process flow.

[0043] In this embodiment, the specific judgment logic for the aircraft component assembly elements that affect the aircraft component assembly connection process flow is as follows: See Figure 4 , the key conditions affecting the aircraft component assembly connection process specification template processes can be logically judged through the process parameter library. Most of the key conditions are the material types of the connecting pieces, which can be obtained through the material library and the standard parts library. In addition, for the special types of high-locks, through the recovered standard parts type library, the two key conditions of high-locks with fixed force and high-locks with nut-breaking cap can be distinguished.

[0044] In this embodiment, according to the aircraft component assembly connection process parameter library, the aircraft component assembly connection process specification template, and the judgment logic, the compilation of the aircraft component assembly connection process specification is specifically as follows: Define the types of aircraft component assembly connection process parameters; During the aircraft component assembly connection process, a large number of process parameters are used, which will involve different types of connectors, different assembly requirements, corresponding connection insurance requirements, recovery inspection requirements, installation setting force requirements, setting force tools, and bonding plate / screw torque inspection requirements for different standard parts.

[0045] See Figure 5 , and the specific logic for obtaining the aircraft component assembly connection process parameters is as follows: Based on the materials in the material library involved in the actual aircraft component assembly connection process, establish the correlation relationship between process parameters, and construct the logic for obtaining the aircraft component assembly connection process parameters; According to the data correlation relationship between process parameter libraries, classify the correlation relationship between each process parameter library to form the one-to-one, one-to-many, and many-to-one correspondence forms between parameter libraries, as well as the single-parameter matching and multi-parameter matching relationships between parameters; through the parameter correlation relationship between parameter libraries, form inference rules, and retrieve the above 6 relationship process parameter libraries according to the rules based on the materials in the material library involved in the actual aircraft component assembly connection process to obtain the connection process parameters; Push the general process parameters to the process uniformly according to the aircraft component assembly connection process specification template name, process name, standard operation procedure library, certified information library, and inspection type library.

[0046] The specific compilation of the process specification by integrating the aircraft assembly digital model information, the aircraft component assembly connection process specification template, and the process parameters is as follows: Based on the designed aircraft component assembly connection process specification template, put the actively retrieved or uniformly pushed aircraft component assembly connection process parameters into the process parameters and process attribute information in the form required by the aircraft component assembly connection process specification template, and the compilation of the aircraft assembly connection process specification can be completed.

[0047] Adopting this embodiment, according to the assembly connection process flow, process experience and process requirements, the design of the aircraft component assembly connection process specification template and the aircraft component assembly connection process parameter library is completed, the assembly connection process parameters for the actual aircraft component assembly connection process are determined, and after obtaining the aircraft component assembly digital model information in the application software, the connection insurance requirements, recovery inspection requirements, installation setting force requirements, setting force tools, as well as the bonding plate / screw torque inspection requirements and general process parameters for different standard parts are quickly called in to complete the compilation of the aircraft assembly connection process specification. Through systematic and intelligent means, the efficiency and quality of the aircraft component assembly connection process design are effectively improved.

[0048] Example 3: This embodiment further optimizes on the basis of the above-mentioned Embodiment 2. In this embodiment, the method for constructing the aircraft component assembly connection process specification template further includes: First, determine the information types included in the process specification, define the generation methods of the information of each component element of the process specification according to the information types, and determine the target component elements; Then, according to the process flow of aircraft assembly, define the hierarchical relationship between the aircraft component assembly connection process specification template and the process specification procedures to determine the structural form of the procedure set and define the corresponding expression methods according to the template types of each type of process specification; define the classification methods of the assembly type, template type, and process specification procedure type, and establish the corresponding relationship between the process specification procedure type and the process specification procedure set to obtain the procedure parameters of the aircraft component assembly connection process specification template. Finally, according to the digital model information of the assembly scenario, obtain the identification conditions of the process specification procedure set to determine the procedure timing. According to the target component elements, hierarchical relationship and corresponding relationship, combine the process specification procedures matching the assembly scenario according to the procedure timing to generate the aircraft component assembly connection process specification template corresponding to the assembly scenario.

[0049] Adopting this embodiment, by analyzing the assembly type and procedure type of aircraft assembly from the essential perspective of assembly, designing the appearance conditions of the procedures in the process flow, and sorting out the logical rules of the key conditions affecting the procedure content, the procedures associated by the rules are presented in the aircraft component assembly connection process specification template in a certain structural form and hierarchical relationship. In the subsequent process specification compilation process, when the digital model information included in the assembly scenario meets the appearance conditions of the procedures, the procedures conforming to the assembly scenario will appear in the process specification, and the content of the procedures can be obtained by combining the process parameter library and the digital model information, realizing the rapid compilation of the aircraft assembly process specification and forming the final complete process specification document; through the design of the aircraft component assembly connection process specification template and the compilation of the process specification procedure content, the compilation efficiency and quality of the process documents can be effectively improved, and the manual workload and human errors can be reduced.

[0050] Furthermore, the information types include operation instructions, processes, and process timings. The processes further include process parameters and parameter information.

[0051] Specifically, the process parameters include information such as the specific location, quantity, and assembly requirements for providing operations, lists of materials, tooling, materials, etc., and parameter information such as certification and standard operating procedures.

[0052] Furthermore, the generation methods of the component element information include at least one of template generation, digital model information generation, or parameter library generation.

[0053] Specifically, according to the timing of information generation in the process specification, for some processes that cannot be known in advance during the process specification compilation, quality information records that need to be gradually improved into the process specification content according to the actual situation during production, as well as design change information starting from late-stage design changes and optimizations, are not considered as part of the aircraft component assembly connection process specification template content. However, some information obtained through logical rule reasoning and process parameter acquisition based on the actual situation of the assembly digital model, as well as some fixed statements, can be incorporated into the aircraft component assembly connection process specification template; Referring to Table 1, the aircraft component assembly connection process specification template consists of operation instructions, processes, and process timings. The operation instructions are like a process that appears fixedly. The processes are processes with timing relationships and reflect the process of the current assembly scenario. The process timings provide the execution sequence between multiple processes.

[0054] Table 1 Furthermore, the hierarchical relationship includes the assembly scenario, the aircraft component assembly connection process specification template, the process set, and the relationship between processes; specifically: each assembly scenario corresponds to at least one aircraft component assembly connection process specification template, each aircraft component assembly connection process specification template contains at least one process set, each process set contains at least one process, and the hierarchical relationship is configured to support decomposition from the aircraft component assembly connection process specification template to processes and combination from processes to the aircraft component assembly connection process specification template.

[0055] Specifically, in this embodiment, the aircraft assembly process flow is divided into multiple levels, including the assembly scenario, the aircraft component assembly connection process specification template, the process set, and the processes. Each level contains rich process information and execution details.

[0056] Furthermore, each process corresponds to a unique process label to distinguish processes with the same name.

[0057] Specifically, in this multi-level structure, each assembly scenario corresponds to multiple aircraft component assembly connection process specification templates. Each aircraft component assembly connection process specification template contains multiple process sets, and each process set may contain multiple processes with the same name. To solve the problem of identifying processes with the same name, this embodiment introduces the concept of "process label". By assigning a unique label to each process, accurate differentiation between processes with the same name is achieved.

[0058] Furthermore, the method for differentiating processes with the same name includes: First, according to the current assembly scenario, select the target aircraft component assembly connection process specification template that matches the current assembly task. Then, according to the target aircraft component assembly connection process specification template, select the target process set that matches the current assembly task and perform a preliminary positioning in the target process set according to the name of the target process. Finally, through the process label corresponding to the target process, locate the target process among the processes with the same name as the target process.

[0059] In an alternative embodiment, the method for differentiating processes with the same name includes the following steps: Determine the assembly scenario, specifically by first clarifying the current assembly scenario, which is the starting point for searching for processes; Select the aircraft component assembly connection process specification template, specifically by selecting, in this assembly scenario, the aircraft component assembly connection process specification template that matches the current assembly task; Locate the process set, specifically by finding, in the selected aircraft component assembly connection process specification template, the process set related to the assembly task; Identify the process name, specifically by performing a preliminary positioning in the process set according to the name of the process; Apply the process label, specifically by finally accurately identifying the target process from the possible processes with the same name through the unique process label.

[0060] Furthermore, the method for determining the structural form of the process set includes: Divide the processes with more than one triggering condition into multiple process sets corresponding to the triggering conditions, and divide the processes that are necessarily triggered in the specified assembly scenario into an independent process set.

[0061] Specifically, the concept of the process set plays a core role in the design of the aircraft component assembly connection process specification template for aircraft assembly. It consists of one or more processes that have common triggering conditions. Each process in the process set will be activated simultaneously when encountering specific material characteristics or process plans. This mechanism ensures that in an assembly scenario that meets specific conditions, the relevant processes can be automatically and synchronously executed, improving the efficiency and consistency of the assembly process; For those processes that are highly versatile and need to be executed under multiple conditions, this implementation method divides them into multiple process sets at the same time.
