Description

Technical Field

[0001] This utility model relates to the field of assembly inspection technology, specifically to a device for detecting assembly errors of aircraft jigs. Background Technology

[0002] Aircraft assembly involves a large number of complex parts, and their precision directly affects flight performance and safety. For example, the assembly precision requirements for components such as fuselage and wings are extremely high. Any tiny error may lead to a decrease in aerodynamic performance or insufficient structural strength. Therefore, high-precision assembly error detection devices have become the key to ensuring aircraft quality.

[0003] Manual inspection is a traditional method in aircraft assembly. Although its efficiency and accuracy are relatively low, it is still widely used in situations with complex surfaces. The following are the main methods and characteristics of manual inspection: Visual inspection: Inspectors visually inspect the appearance, connections, and missing or incorrectly assembled parts. Its advantages are low cost, no need for complex equipment, and high efficiency for obvious appearance defects and missing / incorrectly assembled parts. Manual measurement: Using calipers, micrometers, steel rulers, and other manual measuring tools, the dimensions, gaps, and positional deviations of parts are measured. Inspectors determine whether the measurements meet design requirements. Its advantages are simple equipment, easy operation, direct data reading, and relatively high accuracy. Template inspection: Using metal or plastic templates to fit the surface of parts, the shape of the parts is checked to see if it meets design requirements. Inspectors observe the gap between the template and the part to determine if there are errors. Its advantages are simple operation, strong intuitiveness, and the ability to quickly determine whether parts with complex shapes meet design requirements.

[0004] However, traditional manual inspection methods are time-consuming, labor-intensive, and inefficient. Therefore, mechanical automatic inspection methods have begun to be used in the market. However, although this method is more efficient, it still has the following disadvantages, such as high cost, high cost of automatic inspection devices, lack of flexibility, inability to move automatic inspection devices easily, and complex data processing. When faced with complex curved surfaces, a large amount of data is generated, which leads to a decrease in inspection efficiency. Therefore, a detection device for aircraft jig assembly error has been designed to solve the above problems. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a detection device for aircraft jig assembly errors, so as to solve the technical problem of low efficiency of traditional detection devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detection device for aircraft frame assembly error, comprising a main body, an air intake device installed inside the main body, and the air intake end of the air intake device being connected to a plurality of side air intake ports and a main air intake port, both the main air intake port and the side air intake ports penetrating the main body, and fitting blocks being provided at the openings of the side air intake ports and the main air intake ports on the main body, each of the side air intake ports being connected to a side detection block through a corresponding fitting block, and the main air intake port being connected to a main detection block through a corresponding fitting block, each of the side detection blocks being mounted on a corresponding fitting block.

[0007] By adopting the above technical solution, the staff aligns the main detection block on the main body with the surface of the object, and then starts the suction device. By sensing the negative pressure difference between the main detection block and the side detection block on the interlocking block and the surface of the object, the staff determines whether there is a gap between the surface of the object and the main detection block and the side detection block, thereby completing the detection of the surface of the object.

[0008] The present invention is further configured such that the air intake device is a high-pressure vortex air pump, the output end of the air intake device is connected to an exhaust port, and the exhaust port penetrates the main body.

[0009] By adopting the above technical solution, the output end of the suction device is connected to the exhaust port, making the entire device form a relatively complete airflow circulation system. This allows for the timely discharge of the sucked-in air, preventing excessive internal pressure from affecting the normal operation of the suction device, ensuring the continuous and stable operation of the detection device, and improving the reliability and continuity of detection.

[0010] The present invention is further configured such that a handle is fixed on the main body, and a control switch for controlling the air intake device is installed on the handle.

[0011] By adopting the above technical solution, the handle facilitates the carrying and use of the device, while the control switch on the handle allows the testing personnel to flexibly control the start and stop of the air intake device according to actual testing needs, thus improving the ease of operation.

[0012] The present invention is further configured such that a plurality of pressure gauges are installed on the main body to cooperate with the corresponding main air intake and side air intake.

[0013] By adopting the above technical solution, the barometer can display the air pressure at each main air inlet and side air inlet in real time. The tester can judge the working status of the air intake device and the air flow at the test site based on the air pressure data, thereby helping to judge the assembly error, providing more accurate and intuitive data support for the test, and improving the accuracy and reliability of the test.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention uses an air suction device to detect the gap between the surface of an object and the main and side detection blocks, thereby detecting errors on the object's surface. Furthermore, a pressure gauge displays the air pressure in real time, which helps to determine the working status and assembly errors of the air suction device, thus improving detection accuracy and reliability.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A device for detecting assembly errors of aircraft jigs, such as Figure 1-4 As shown, the device includes a main body 1, inside which a suction device 4 is installed. The suction end of the suction device 4 is connected to several side suction ports 6 and a main suction port 5. Both the main suction port 5 and the side suction ports 6 penetrate the main body 1. The main body 1 is provided with a fitting block 8 at the opening of the side suction ports 6 and the main suction port 5. Each side suction port 6 is connected to a side detection block 10 through a corresponding fitting block 8. The main suction port 5 is connected to a main detection block 9 through a corresponding fitting block 8. Each side detection block 10 is installed on a corresponding fitting block 8. The operator aligns the main detection block 9 on the main body 1 with the surface of the object, and then starts the suction device 4. By sensing the negative pressure difference between the main detection block 9 and the side detection block 10 on the fitting block 8 and the surface of the object, the operator determines whether there is a gap between the surface of the object and the main detection block 9 and the side detection block 10, thereby completing the detection of the surface of the object.

[0024] The suction device 4 is a high-pressure vortex air pump. The output end of the suction device 4 is connected to the exhaust port 7, and the exhaust port 7 penetrates through the main body 1. The connection between the output end of the suction device 4 and the exhaust port 7 forms a relatively complete airflow circulation system for the entire device. This allows for timely discharge of the sucked-in air, preventing excessive internal pressure from affecting the normal operation of the suction device 4, ensuring the continuous and stable operation of the detection device, and improving the reliability and continuity of the detection.

[0025] A handle 2 is fixed on the main body 1, and a control switch 3 for controlling the air intake device 4 is installed on the handle 2. The handle 2 makes it convenient to carry and use the device, while the control switch 3 on the handle 2 allows the testing personnel to flexibly control the start and stop of the air intake device 4 according to the actual testing needs, thus improving the convenience of operation.

[0026] The main body 1 is equipped with several pressure gauges 11 that cooperate with the corresponding main air intake 5 and side air intake 6. The pressure gauges 11 can display the air pressure at each main air intake 5 and side air intake 6 in real time. The testers can judge the working status of the air intake device 4 and the air flow at the test site based on the air pressure data, thereby helping to judge the assembly error, providing more accurate and intuitive data support for the test, and improving the accuracy and reliability of the test.

[0027] Working principle: The operator aligns the main detection block 9 on the main body 1 with the surface of the object, and then starts the suction device 4 by controlling the switch 3 on the handle 2. The air pressure at each main air inlet 5 and side air inlet 6 is displayed in real time by the air pressure gauge 11, thereby detecting whether there are gaps between the main detection block 9 and side detection block 10 on the interlocking block 8 and the surface of the object, and further detecting the error of the object surface. In addition, the output end of the suction device 4 is connected to the exhaust port 7, so that the whole device forms a relatively complete airflow circulation system.
