Description

Technical Field

[0001] This invention belongs to the field of aircraft engine repair and manufacturing technology, and specifically relates to a method and system for improving the assembly quality and efficiency of small parts of aircraft engines. Background Technology

[0002] The assembly and disassembly of aircraft engines involves a large number of small parts, which are characterized by similar shapes, a wide variety and large quantity, and small size.

[0003] These characteristics make it easy for small parts to be mixed, misassembled, or missing, resulting in low accuracy in inventory counts, long handover times, and easy loss. The lack of verification process for essential replacement parts after disassembly poses a risk of leaving them at the scene, creating a huge hidden danger to engine safety.

[0004] Currently, the industry mainly relies on operators to manually complete the counting, classification, labeling, and handover verification of small parts. During assembly, parts are picked up based on experience, and disassembled replacement parts are directly put into the scrap bin without a dedicated verification and counting process.

[0005] Manual operation relies on personal experience, making it difficult to distinguish similar parts, resulting in low accuracy in inventory counts and time-consuming handover processes. Small parts are difficult to label due to their small size, making them prone to loss. Essential replacement parts are discarded without verification, leaving loopholes on-site. Furthermore, manual assembly is prone to omissions, misassemblies, and the leaving of excess materials, failing to effectively mitigate safety risks. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for improving the assembly quality and efficiency of small parts in aircraft engines, so as to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for improving the assembly quality and efficiency of small parts in aircraft engines, comprising: Acquire assembly process data for aircraft engines, decompose the assembly data, and form assembly sequence data ordered by the order of assembly processes. Based on assembly sequence data and combined with preset part shape data, shape-based separation templates for different part types are formed. Based on the assembly sequence data and the shape-based partition template, small parts are placed into the corresponding template partition areas of the shape-based partition template; During assembly, assemble according to the assembly process and the arrangement order of small parts in the template until there are no remaining parts, and the corresponding assembly is completed; during disassembly, put all the disassembled small parts into the template according to the partition area, and check the integrity of the parts by checking whether the template is empty.

[0008] Furthermore, the acquisition of aircraft engine assembly process data, decomposition of assembly data, and formation of assembly sequence data ordered by the order of assembly processes include: Identify the target engine model and its corresponding assembly stage, and define the scope of all assembly steps that need to be covered within that stage. Based on the defined assembly step scope, identify the specific part numbers and corresponding quantities of the small parts required in each step, and mark information on easily confused similar parts. According to the engine assembly process logic, classify and collect the part numbers and quantity data corresponding to each step in the order of step execution to ensure that the part data of each step corresponds one-to-one with the step sequence. Verify all the collected data and integrate them to form assembly sequence data.

[0009] Furthermore, the step of dividing and forming shape-based separation templates for different part types based on assembly sequence data and preset part shape data includes: First, the part numbers and quantities of small parts corresponding to each step in the assembly sequence data are matched one by one with the preset part shape data. Then, all the associated parts are classified according to their type attributes. Next, for each type of part, an independent partition area is designed to match its shape data, ensuring that the inner contour and size of the partition area completely match the corresponding part, and that the quantity of each partition area strictly matches the required quantity of the part in the assembly sequence data, forming a trace structure. Then, according to the sequential logic of the steps in the assembly sequence data, the partition areas of various parts are arranged in an orderly manner on the template, and the step number and part number information are marked at the corresponding positions on the template.

[0010] Furthermore, the part shape data includes the actual size, contour features, and thickness parameters of the part, and the part type attributes include screws, rubber rings, washers, and nuts.

[0011] Furthermore, the step of placing small parts into the template partition areas of the template based on assembly sequence data and the shaped partition template includes: Install the shape-based partition template and insert the small parts in sequence according to the assembly steps. At this time, there are no gaps in the shape-based partition template.

[0012] Furthermore, during assembly, based on the corresponding shape-based partition template, the range of work steps, the work step number on the template, the part number, and the assembly process are checked against the assembly procedure. The assembly operation is then initiated. Following the template sequence, parts are retrieved step by step from the corresponding shape-based partition area. During retrieval, the shape matching degree between the part and the partition area is checked. After the part is retrieved, it is immediately assembled to the designated position on the aircraft engine. After the assembly is completed, it is confirmed that the template partition area corresponding to the part is empty before retrieving and assembling the next part. After each work step is completed, it is checked whether there are no remaining parts in all template partition areas corresponding to that work step. This process continues until all template partition areas in the small parts box are empty and all assembly procedures are completed. During disassembly, first prepare a shape-based partition template that matches the model of the engine to be disassembled. Remove small parts one by one according to the engine disassembly process. After removal, immediately check whether the shape and size of the parts match the shape of each partition area on the template, and confirm the corresponding part type and part number. Accurately place the disassembled parts that have been verified into the matching partition areas in the template. After all disassembly is completed, check row by row and column by column whether all partition areas on the template are filled.

[0013] Secondly, the present invention provides a system for improving the assembly quality and efficiency of small parts in aircraft engines, comprising: The data acquisition module is used to acquire assembly process data of aircraft engines, decompose the assembly data, and form assembly sequence data sorted by the order of assembly processes. The template acquisition module is used to divide and form shape-based partition templates for different part types based on assembly sequence data and preset part shape data. The filling module is used to fill small parts into the template separation area of ​​the template according to the assembly sequence data and the shape separation template; The assembly and disassembly module is used to assemble parts according to the assembly process and the arrangement order of small parts in the template during assembly until no parts remain, thus completing the corresponding assembly. During disassembly, all disassembled small parts are placed into the template according to the partition areas, and the integrity of the parts is checked by checking whether the template is empty.

[0014] Furthermore, the acquisition of aircraft engine assembly process data, decomposition of assembly data, and formation of assembly sequence data ordered by the order of assembly processes include: Identify the target engine model and its corresponding assembly stage, and define the scope of all assembly steps that need to be covered within that stage. Based on the defined assembly step scope, identify the specific part numbers and corresponding quantities of the small parts required in each step, and mark information on easily confused similar parts. According to the engine assembly process logic, classify and collect the part numbers and quantity data corresponding to each step in the order of step execution to ensure that the part data of each step corresponds one-to-one with the step sequence. Verify all the collected data and integrate them to form assembly sequence data. The method of dividing and forming shape-based separation templates for different part types based on assembly sequence data and preset part shape data includes: First, the part numbers and quantities of small parts corresponding to each step in the assembly sequence data are matched one by one with the preset part shape data. Then, all the associated parts are classified according to their type attributes. Next, for each type of part, an independent partition area is designed to match its shape data, ensuring that the inner contour and size of the partition area completely match the corresponding part, and that the quantity of each partition area strictly matches the required quantity of the part in the assembly sequence data, forming a trace structure. Then, according to the sequential logic of the steps in the assembly sequence data, the partition areas of various parts are arranged in an orderly manner on the template, and the step number and part number information are marked at the corresponding positions on the template.

[0015] Thirdly, the present invention provides a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method for improving the assembly quality and efficiency of small parts of an aircraft engine.

[0016] Fourthly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method for improving the assembly quality and efficiency of small parts of an aircraft engine.

[0017] Compared with the prior art, the present invention has the following technical effects: This invention utilizes templates to pre-control the type, quantity, and sequence of small engine parts during assembly. The templates rigorously control the correctness of part requisition and assembly, reducing reliance on manual labor and minimizing human error. During assembly, parts are arranged according to their order, allowing operators to retrieve parts sequentially, reducing the possibility of errors due to similarity and saving time during the sorting process. During disassembly, the whereabouts of small parts are strictly controlled, ensuring all disassembled parts leave the disassembly area. The small parts box demonstrates the efficiency of the shadow template during handover, providing a clear overview and significantly shortening handover time. The invention achieves precise, quantitative, and traceable management of small parts such as rubber rings, gaskets, screws, and nuts during engine assembly and disassembly, effectively improving the quality and efficiency of aircraft engine small parts assembly. Attached Figure Description

[0018] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings: Example 1, please refer to Figure 1 This invention provides a method for improving the assembly quality and efficiency of small parts in aircraft engines, comprising: Acquire assembly process data for aircraft engines, decompose the assembly data, and form assembly sequence data ordered by the order of assembly processes. Based on assembly sequence data and combined with preset part shape data, shape-based separation templates for different part types are formed. Based on the assembly sequence data and the shape-based partition template, small parts are placed into the corresponding template partition areas of the shape-based partition template; During assembly, assemble according to the assembly process and the arrangement order of small parts in the template until there are no remaining parts, and the corresponding assembly is completed; during disassembly, put all the disassembled small parts into the template according to the partition area, and check the integrity of the parts by checking whether the template is empty.

[0020] Example 2: This invention provides a method for improving the assembly quality and efficiency of small parts in aircraft engines, comprising: (1) Small parts sorting during assembly stage: According to the assembly process requirements, the part numbers and quantities of small parts assembled at different stages are sorted and organized to form an assembly sequence list.

[0021] (2) Design a shadow template: The template separates each small part. The small parts are arranged in the assembly order and the model is made. The quantity and shape match perfectly to form a "shadow template".

[0022] (3) Control of the assembly stage: The small parts are packed in advance according to the assembly process and the small parts are loaded in sequence according to the assembly steps. At this time, there should be no gaps in the template to ensure the quality and correctness of the small parts. When checking and handing over, just observe whether there are any missing parts on the whole small parts box model.

[0023] (4) Assembly stage control: Take small parts in sequence according to the assembly process and assemble them. After assembly, ensure that there are no leftover parts in the small parts box, then the assembly is complete.

[0024] (5) Disassembly stage control: When disassembling again, operators are required to pack all the disassembled small parts into the small parts box according to the template, ensuring that all parts are filled without gaps. The next department shall check whether all the disassembled small parts are complete and ensure that all disassembled small parts have left the assembly site.

[0025] This invention addresses the pain points of managing small aircraft engine parts through a triple-collaboration approach of "data organization + shape constraints + process standardization." First, assembly processes and part information are transformed into ordered data. Then, templates tailored to the shapes of the parts are used to visualize and standardize the data, creating clear constraints on the quantity, location, and assembly sequence of parts. Finally, the operational logic of "sequential retrieval and gap verification" reduces reliance on operator experience, preventing issues such as mixed assembly, incorrect assembly, omissions, and losses from the outset.

[0026] First, identify the target engine model and assembly stage. Then, compile the part numbers and quantities of small parts required for each step, and label similar parts. Collect and verify these parts according to the process sequence to form assembly sequence data. Next, associate this data with the shape data of the parts, such as dimensions, contours, and thicknesses. Classify parts by type, such as screws and rubber rings, and design a "one-piece-one-position" partition area. Arrange these areas according to the process sequence and label key information to create a tactile template. During assembly, fill the template with the corresponding parts, ensuring no gaps. During assembly, check the template information and retrieve the parts in sequence. After assembly, confirm that the corresponding positions are empty. Verify each step is complete when there are no remaining parts. During disassembly, use a matching template to disassemble and reassemble each part. After complete disassembly, check if the template is filled.

[0027] The form-based template makes parts "traceable," and similar parts cannot be misplaced due to different clamping shapes. Sequential operation avoids omissions and significantly reduces human error. During assembly and handover, the template gaps allow for intuitive verification, eliminating the need for item-by-item counting and significantly shortening the time required. No picking is required during assembly, and the destination of parts is clear during disassembly, effectively preventing loss and leaving anything behind on-site. The entire process is intuitive, allowing even inexperienced operators to quickly get started. At the same time, it enables precise control of small parts throughout the entire process, improving assembly quality and efficiency while ensuring engine safety.

[0028] Example 3: This invention provides a method for improving the assembly quality and efficiency of small parts in aircraft engines, comprising: (1) Small parts sorting during assembly stage: According to the assembly process requirements of the first stage of the final assembly JR90802, step 2455 involves 28 small parts of category 1 U125945; step 2495 involves 3 small parts of category 3 KU6537, 3 RU9286, and 6 KU10005; classify the part numbers and quantities of all small parts involved in steps 2455-2695 to form an assembly sequence list.

[0029] (2) Use a foam board template to separate each small part. The small parts are arranged in the assembly order and a model is made. The quantity and shape are matched. They are arranged in the order of the assembly order list, from left to right and from top to bottom. The parts are filled in a fixed position and quantity to form a "shadow template". All the small parts involved are divided into 6 templates and stored in boxes of the same size to form small parts boxes. The small parts boxes are marked with the total number of boxes - which box, to ensure that even inexperienced operators will not make a mistake in the order.

[0030] (3) Control during the assembly and distribution stage: According to the task arrangement, the assembly and distribution department will sort the boxes according to the assembly process 5 days in advance and place them in the order of the assembly steps. The boxes will also be checked against the small parts catalog to ensure quality and accuracy. During the handover, it is only necessary to observe whether there are any missing parts on the inner mold of the model. The handover time has been reduced from 3 hours to 20 minutes, and the accuracy rate is high. (4) Assembly stage control: The assembly department takes small parts in sequence according to the assembly process and assembles them, no longer worrying about the minor differences between screws and washers, thus improving assembly efficiency. If a part is missed, it will be found on the template later, which will remind the operator that a small part in a certain process or step has not been assembled.

[0031] (5) Decomposition stage control: When decomposing again, the operator will put all the decomposed small parts into the small parts box in reverse order according to the template. When there is a missing part, the template will be detected immediately, and the operator can find it immediately, which is very efficient.
