Description

Technical Field

[0001] The invention relates to the field of digital technology, and in particular to a method for efficiently compiling aircraft assembly instructions. Background Art

[0002] The flight assembly instruction is a series of work that is carried out directly on the product object to make it undergo physical or chemical changes of the same nature in order to achieve the design requirements of product size, performance, etc. It is a process document for implementing quality control of the assembly and test process and recording production and inspection conditions. To complete the manufacturing, assembly, debugging, and test flight of an aircraft, more than a thousand assembly instructions need to be compiled. Large aircraft even contain more than 6,000 or even tens of thousands of assembly instructions. It takes a few hours to several days to compile an assembly instruction document, and it is easy to miss / miscompile operating elements and compile irregularities. Therefore, how to quickly compile assembly instructions with accurate arguments, concise content, and strong practicality can fundamentally improve the standardization and standardization of assembly instruction compilation, enhance the operability of assembly instructions, promote the completion of aircraft production nodes as planned, and improve production efficiency, which has great theoretical and practical significance.

[0003] At present, the assembly instructions mainly have the following problems:

[0004] 1. The efficiency of assembly instruction preparation is low. The production site often waits for instructions to work. According to the general level of the technicians, it takes about (3-6) hours to prepare an assembly instruction, and sometimes several days. With limited technicians, in order to ensure the progress of aircraft development, they can only work overtime to prepare the instruction documents. Especially when temporary and urgent work such as rework, repair, troubleshooting, and inspection occurs on site, the low efficiency of assembly instruction document preparation will limit the progress of production site work.

[0005] 2. Different people describe the same process differently. Each technician has very different professional cognition, knowledge reserves, and use of engineering language. As a result, the text description of the same process is different for each person. Workers have to spend time and energy to confirm the content of the instructions, and the readability and operability of the assembly instructions are poor.

[0006] 3. Failure to fully implement the design technical documents or process specification technical requirements, and omission of process control elements and documentation requirements;

[0007] 4. Multiple citations, missing citations, and mis-citations in assembly instruction technical documents and product drawings;

[0008] 5. The content of the process instruction is inconsistent with the implementation clauses required by the technical conditions;

[0009] 6. The operator's recorded data does not meet the requirements;

[0010] 7. The control requirements for some processes are not detailed and comprehensive enough;

[0011] 8. Lack of knowledge accumulation and sedimentation;

[0012] 9. The degree of process standardization is low. Some technicians have sorted out the entries that are often used in the compilation of their own assembly instructions during their long-term work accumulation to facilitate their personal work needs and improve the compilation efficiency to a certain extent. However, there is no unified consensus among different technicians and different assembly process professional groups, and no unified, standardized, and normative standard entries have been formed. To a certain extent, process standardization has not been formed at all. For teams with this awareness, the degree of process standardization and readability of assembly instructions are also very low.

[0013] The present invention is based on knowledge engineering, implements assembly instruction process standardization, establishes an assembly instruction standard description library, and calls typical assembly process standard description entries in the library during the assembly instruction compilation process, thereby achieving high efficiency and standardization of assembly instruction compilation. Summary of the invention

[0014] In view of the deficiencies in the prior art, the present invention provides a method for efficiently compiling aircraft assembly instructions, which solves the problems of low efficiency, high error rate, low professionalism, non-compliant operations and poor process standards in the compilation of assembly instructions in the existing aircraft assembly process.

[0015] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for efficiently compiling aircraft assembly instructions, comprising the following steps;

[0016] Step 1: Sort out the standard description terms for aircraft assembly processes. For each aircraft assembly profession, such as power, environmental control, fuel, hydraulics, control, component assembly, etc., sort out the common typical processes and special typical processes for each profession, and compile common standard description terms and special standard description terms respectively.

[0017] Step 2: Establish an assembly instruction standard description library. By building the system function page, the entire aircraft assembly process is sorted out according to the process steps and then the function page is established. The page is arranged in a general-division-subdivision structure to achieve page folding of major professional categories and minor professional categories. At the same time, independent pages are set for some general process descriptions. The establishment of the assembly instruction standard description library is based on the assembly process project of the entire aircraft as the main directory to establish major professional categories. Each major professional category contains different minor professional categories, and the minor professional categories are subdivided into minor professional categories. General descriptions are set in parallel with each major professional category, and the general descriptions cover the standard description terms common to each assembly process profession.

[0018] Step 3: Assembly instruction compilation call. When compiling specific assembly instructions, directly call the entries in the assembly instruction standard description library to compile and quickly form a specific assembly instruction process instruction file. When calling the assembly instruction standard description entry, each professional project can be searched step by step according to the framework of the standard description library, or the name or name keyword of the standard description entry can be searched and displayed in a list form. Select the appropriate entry from the assembly instruction standard description library, insert the corresponding reference, and modify the referenced inserted description according to the actual process scenario to form the assembly instruction compilation.

[0019] Preferably, the standard description entries include all typical operations of the aircraft assembly process, and each typical process item is organized into a typical operation catalog after full professional discussion, and then undergoes process review.

[0020] Preferably, during the process review, if the review fails, it will be discussed again by all professionals. If the review passes, professional-specific description sets and general description sets will be compiled according to the special and general categories. After compilation, they will pass the internal review of the specific profession. The standard entries that pass the review will be included in the standard description library. If the review fails, it will be returned for modification and enter the corresponding description set compilation again.

[0021] Preferably, the assembly instruction compilation includes a general project entry, which is subdivided into various professional project entries. Each professional project entry includes operating methods, operating precautions, assembly record elements or record forms, and assembly parts, tooling, tools and process materials used in each typical process.

[0022] Preferably, the special standard description entries include typical processes specific to each profession, and such special entries are included in the corresponding professional project entries.

[0023] Preferably, after the step three is completed, a preview list is generated, and preview is performed according to the preview list. The preview list can be modified for a second time, and the assembly instruction process instruction file is regenerated after the modification.

[0024] Preferably, in the step 2, when dividing professional subcategories and professional subcategories, the same professional subcategory covers multiple professional subcategories with different implementation methods, and each professional subcategory is annotated with the process characteristics of the subcategory for distinction when selecting a specific professional subcategory during assembly instruction compilation.

[0025] The present invention discloses a method for efficiently compiling aircraft assembly instructions, which has the following beneficial effects:

[0026] The method for efficiently compiling aircraft assembly instructions is to sort out the entries of each typical process covered in the existing aircraft assembly process, so as to form a unified and standardized description entry. When compiling a specific assembly instruction, the entry in the assembly instruction standard description library is directly called. On the one hand, it can ensure the uniformity and professionalism of the entry, improve the standardization, readability and operability of the assembly instruction, and reduce the problems of missing / wrong compilation operation elements and non-standard compilation. On the other hand, the compilation speed is faster, more convenient and smoother, and the construction work is carried out according to the standard description entries in the standard description library, so the process is more standardized and the production efficiency is improved.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0035] The embodiments of the present application provide a method for efficiently compiling aircraft assembly instructions, thereby solving the problems of low efficiency, high error rate, low professionalism, non-compliant operations and poor process standards in the compilation of assembly instructions in the existing aircraft assembly process.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] The embodiment of the invention discloses a method for efficiently compiling aircraft assembly instructions.

[0038] According to the attached Figure 1 -6, including the following steps;

[0039] Step 1: Edit the overall process of the aircraft assembly instruction, the processes included in each process, the workpieces and construction steps involved in each process, the specific content and precautions in a unified manner. The description entries include general standard description entries for each profession and standard description entries dedicated to each professional group. General standard description entries are applicable to the implementation of a specific identical process in each profession, and dedicated standard description entries are dedicated to the compilation of a specific professional assembly instruction;

[0040] Generally, it is divided into common standard description terms for each profession and special standard description terms for each professional group. Examples of common typical assembly process standard description terms are as follows:

[0041] 1) Fillet seal - MS 23D01-B

[0042] After cleaning with acetone according to PS D1000, use MS 23D01B sealant to fillet and seal the following locations and record them according to the table below:

[0043] 1. The edges of the mating surfaces of A (component) and B (component);

[0044] 2. The edges of the C (component) and D (component) surfaces are fitted together.

[0045]

[0046] 2) Cleaning and removal of excess items

[0047] The entry content is as follows:

[0048] 1. After the construction is completed, check the excess materials and count the items on site, and conduct key inspections in the construction area;

[0049] 2. Clean / collect the aluminum chips and other excess materials generated during the work process;

[0050] 3. Process materials used for cleaning, such as rags, acetone, paper tape, etc.;

[0051] 4. After getting off the plane, check the tools, technical data and other items to ensure that nothing is lost;

[0052] 5. The collected excess materials shall be classified according to the requirements of the production site and placed in the relevant recycling equipment.

[0053] 3) Primer

[0054] Primer - MS25D03 - Local touch-up on composite surface - (512X310)

[0055] The entry content is as follows:

[0056] According to PS D1100, sand and clean area E, apply N layers (number of layers as required) of MS25D03 primer, and fill in the record.

[0057]

[0058] Primer - MS25D02 - Partial touch-up of the fuel tank area (primer already applied, metal substrate not exposed)

[0059] The entry content is as follows:

[0060] After cleaning and activating the G area according to PS D3100, apply N layers (number of layers as required) of MS25D02, Type Ⅰ, Class 1, Class A primer and fill in the records.

[0061]

[0062] Key words such as file number, area and specific process parameters are marked, which are the contents that can be changed according to the requirements of specific product drawings, technical documents, process specifications, etc. The other parts are general descriptions. Generally speaking, gluing, sealing, primer coating, topcoat coating, general inspection process, corrosion inhibitor coating, etc. can all be classified as general standard descriptions.

[0063] Special standard description entries refer to professional and specialized process operation techniques for avionics, electrical, hydraulic, component assembly, power, environmental control, fuel, hydraulics, etc. For example, the connection of terminal blocks (special for avionics and electrical), firewall sealing (special for component assembly), etc., which can be sorted out as needed.

[0064] This method has clear and complete control elements, standardized file content, and greatly improved readability and operability of assembly instructions. The most important thing is that technicians call these modules to compile files, which greatly improves the efficiency of file compilation. The traditional aircraft assembly instruction compilation not only has very high requirements on the professional and business capabilities of the compilers, but also takes a lot of time and is prone to errors in actual compilation, which requires multiple proofreadings later, affecting the efficiency of instruction compilation.

[0065] Step 2: Establish a standard description library for assembly instructions. By building the system function page, the entire aircraft assembly process is sorted out according to the process steps and then the function page is established. The page is arranged in a general-divided-subdivided structure to achieve page folding of major professional categories and minor professional categories. At the same time, a separate page is used to display the general standard description. The establishment of the standard description library for assembly instructions is based on the entire aircraft assembly process profession as the main directory to establish major professional categories. Each major professional category contains different minor professional categories. At the same time, the minor professional categories are subdivided into minor professional categories, and general descriptions are set in parallel with each major professional category. The general description covers the standard description items shared by each profession.

[0066] For specific structural forms, please refer to the attached Figure 4 -6. The entire instruction standard description library system has a complete full-process flow tree diagram and detailed process level parent-child relationship project folding. When actually using the search, you can click to search according to the process logic line. Through page folding, it is convenient to quickly find the corresponding instruction entry content according to actual needs when compiling instructions; each professional project can be searched level by level according to the framework of the standard description library, or by standard description entry name or name keyword, and a list of related entries will be displayed.

[0067] Step 3: When compiling specific assembly instructions, directly call the entries in the assembly instruction standard description library to compile and quickly form a specific assembly instruction process instruction file. When calling the assembly instruction standard description entry, you can search for each professional project step by step according to the framework of the standard description library, or you can search by the name or name keyword of the standard description entry, display it in a list, select the appropriate entry from the assembly instruction standard description library, insert the corresponding reference, modify the referenced inserted description according to the actual process scenario, and form the assembly instruction compilation.

[0068] In step one, when sorting out the description terms, they are generally divided into general standard description terms and standard description terms dedicated to each professional group. The general standard description terms are applicable to the reference of the same typical processes in various professions; the dedicated standard description terms of each professional group are dedicated to the compilation of assembly instructions for a specific profession. They are based on knowledge engineering and the universality of aircraft models. They make the process knowledge implicit in the technicians explicit, and finally compile standard description terms for assembly instructions with professional universality.

[0069] The following is the gluing process in the typical assembly process standard description entry;

[0070] Process content: Mix the glue according to J requirements:

[0071] 1) Before applying glue, stir the glue evenly and pour it into a clean container.

[0072] 2) If the concentration of XY401 is too high and inconvenient for construction, you can add a mixed solvent to dilute it (ethyl acetate and NY-120 gasoline are mixed in a mass ratio of 2:1) and mix them evenly.

[0073] 3) Use a clean brush to evenly apply the glue on the two bonding surfaces and let it sit for 8 to 10 minutes.

[0074] 4) Apply the second layer of glue evenly on the surface of the first layer of glue and let it dry for 5 to 6 minutes.

[0075]

[0076] 5) Curing at room temperature, fix with tape, nails, etc. to ensure that the two bonding surfaces are tightly fitted, maintain contact pressure for 24 hours to complete curing, and remove the clamp after curing.

[0077] The standard description entries include typical process items for aircraft assembly. Each typical operation item is organized into a typical operation catalog after discussion among all professionals, and then undergoes process review. If the review fails, it will be discussed by all professionals again. After the review passes, professional-specific description sets and general description sets are compiled according to special and general. After compilation, they pass internal review of specific professions. Standard entries that pass the review are included in the standard description library, and those that fail the review are returned for modification and re-enter the corresponding description set compilation. During the entire entry compilation process, the names of general entries that are not controversial are directly included, and some non-standard entries with inconsistent expressions are evaluated through professional reviews in this field, and finally a unified and definite description entry is formed to facilitate corresponding searches when compiling subsequent assembly instructions.

[0078] The assembly instruction compilation includes a general item entry, which is subdivided into various professional item entries. Each professional item entry includes operation methods, operation precautions, assembly record elements or record forms, and assembly parts, tooling, tools and process materials used in each typical process.

[0079] The assembly instruction compilation is generally presented as a general-specific framework flow chart.

[0080] In step 3, during the compilation of assembly instructions, the entries in the standard description library are quickly called, and fine-tuned as needed to quickly complete the compilation of assembly instructions. For assembly instructions that reference standard description entries containing a large number of documentary tables, the effect on efficiently compiling assembly instructions is more obvious.

[0081] After the compilation is completed in step S4, a preview list is generated, and the preview is performed according to the preview list. The preview list can be modified for a second time, and the assembly instruction file is regenerated after the modification.

[0082] In step 2, when dividing professional subcategories and professional subcategories, the same professional subcategory covers multiple professional subcategories with different implementation methods. The process characteristics of each professional subcategory are noted after each professional subcategory, which is used to distinguish when selecting specific professional subcategories during assembly instruction compilation.

[0083] The method forms unified and standardized description terms by combing the terms of typical processes covered in the existing aircraft assembly processes, and then establishes an assembly instruction standard description library, and establishes a professional term library including typical process modules, process flow descriptions, assembly record tables, etc. with aircraft assembly processes as indexes. When compiling a specific assembly instruction, the terms in the assembly instruction standard description library are directly called. On the one hand, the terms can be unified and professional, and the standardization, readability, and operability of the assembly instructions can be improved, and the problems of missing / wrong compilation operation elements and non-standard compilation can be reduced. On the other hand, the compilation speed is faster, more convenient, and smoother, and the construction work is carried out according to the standard description terms in the standard description library, so the process standardization is higher.

[0084] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
