Description

Technical Field

[0001] The invention belongs to the technical field of aircraft assembly detection, and relates to a method for quickly detecting the insertion amount of a conduit of an aircraft fuel system. Background Art

[0002] Aircraft fuel pipe assembly is the key to ensure the safe operation of the fuel system. Traditional detection methods rely on manual measurement and experience judgment, which is not only inefficient, but also difficult to meet the accuracy requirements. There are large errors when manually using steel rulers, feeler gauges, and gauge blocks for inspection. Therefore, a high-precision, automated detection technology is needed to solve the above problems.

[0003] Displacement sensors and linear laser sensors have the characteristics of non-contact, high precision and high stability. Based on the two sensors, the present invention proposes a new automatic inspection method for the insertion amount and eccentricity of the aircraft fuel pipe flange. Through data processing algorithms and three-dimensional modeling technology, high-precision and automatic detection of parameters is achieved. The inspection device can continuously collect data during the rotation around the pipe, generate a three-dimensional model of the pipe in real time, and compare and analyze it with the theoretical model, thereby intuitively displaying the deviation. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a method for quickly detecting the insertion amount of an aircraft fuel system conduit, which will significantly improve the safety and reliability of fuel system conduit assembly while reducing labor costs and potential operational risks.

[0005] The technical solution of the present invention is as follows:

[0006] Principle of testing the insertion amount of the aircraft fuel system pipe

[0007] The insertion depth of the aircraft fuel system conduit refers to the depth of insertion of two conduits used together when connected. Insufficient insertion depth will cause excessive vibration in the fuel system process, which will cause interruption or instability of fuel supply and affect flight safety. Therefore, the insertion depth of the fuel system conduit directly affects the sealing and reliability of the connection and is an important parameter. The insertion depth h1 is defined as the distance from the lower end face of the inserted conduit to the upper end face of the part into which the conduit is inserted. The eccentricity △D=(D1-D2) / 2, see Figure 7 .

[0008] The traditional detection method is to insert a steel ruler into the inserted conduit, align the starting point of the steel ruler with the lower end surface of the inserted conduit, keep the steel ruler vertically close to the conduit and measure the conduit insertion amount h1, and measure the extreme value range of the eccentricity △D=D1-D2 through a feeler gauge, a gauge block or a steel ruler. The following problems exist in the measurement process of the traditional method, such as the steel ruler cannot be kept close to the conduit, the steel ruler is difficult to keep vertical, and the lower end of the conduit cannot be accurately positioned, etc. The above problems need to be improved. The present invention will improve the measurement method of the two parameters of the aircraft fuel system conduit insertion matching, the insertion amount h1 and the eccentricity △D, and control the two important parameters through digital measurement means.

[0009] Method for testing the insertion distance h1 of the aircraft fuel system conduit

[0010] like Figure 8 As shown, the present invention utilizes a displacement sensor to realize digital detection of the insertion amount. One end of the sensor's Z-shaped structural probe is fixed on the slide rail of the detection device, and the other end is forced to displace as the lower edge of the catheter is inserted. The structural probe moves in the slide rail groove of the detection device, and its moving distance is captured and collected by the displacement sensor. When the catheter is assembled in place, the precise measurement of the insertion amount of the catheter circumference is realized by the rotating platform.

[0011] Method for detecting eccentricity △D of aircraft fuel system pipe

[0012] The present invention utilizes the non-contact high-precision measurement capability of the linear laser sensor to realize the digital detection of the flange eccentricity. Traditional tools such as feeler gauges and steel rulers can usually only provide single-point or discrete-point measurement data, while the linear laser sensor can continuously collect data during the rotation of the catheter and cooperate with a high-precision rotating platform to ensure continuous measurement of the catheter circumference. The linear laser sensor emits laser light and receives reflected light to realize high-precision scanning of the catheter surface profile, thereby calculating the eccentricity of the catheter. The structure of the linear laser sensor is as follows: Fig. 9 shown.

[0013] Aircraft fuel system duct inspection data collection principle

[0014] The detection data collection principle is divided into two parts: displacement sensor and linear laser sensor.

[0015] The displacement sensor detects the displacement change of the Z-shaped structure probe due to the forced pressure. The movement distance is converted into an electrical signal and transmitted to the processing unit for analysis through the data acquisition unit. The processing unit determines whether the insertion amount meets the requirements according to the pre-set product design inspection standard, and displays the results in real time. It triggers an alarm when it exceeds the allowable range. The detection principle of the displacement sensor is as follows: Fig.10 shown.

[0016] The linear laser sensor is fixed on the inserted catheter, which continuously emits and receives reflected lasers. The received light signals are converted into electrical signals by the photodetector, enhanced by the signal amplifier, and then converted into digital signals by the analog-to-digital converter. The processor calibrates and fits the collected data points through the algorithm, and constructs a three-dimensional model of the collected data. Finally, it is compared and analyzed with the imported theoretical model and conclusions are drawn. The operator can observe the measurement data and analysis reports through the user interface. The detection principle of the linear laser sensor is as follows: Fig.11 shown.

[0017] Combining the above principles and design solutions, the following technical solutions will be adopted to solve the technical problems to be solved:

[0018] The present invention realizes digital measurement of parameters related to the insertion amount of a conduit pipe of an aircraft fuel system based on a displacement sensor and a linear laser sensor.

Finally, a conclusion is drawn through comparative analysis with the imported model, and a data measurement result and analysis report are made.

[0022] The rapid detection method of the aircraft fuel system catheter insertion volume is as follows:

[0023] Step 1: Check the rotating platform, insertion inspection module and eccentricity inspection module before work. Check whether the appearance of the rotating platform structure is in good condition and whether the module can rotate normally on the slide rail; when powered on, check whether the electronic equipment such as the display screen on the module device is in good condition; confirm that the life parts such as the power circuit of the inspection module are within the validity period.

[0024] Step 2: Select the corresponding diameter series of pipe orifice chucks according to the diameter of the inspected catheter and pre-install them on the flange or pipe orifice of the inserted catheter. Tighten the telescopic adjustment rod by rotating the clamping bolt to ensure that the chuck is firmly fixed on the flange of the catheter. Use the connecting bolts to connect the rotating table and the chuck and tighten them.

Manually rotate the device housing at a constant speed and observe the changes in the values ​​on the digital display screen.

The system also has a diagnostic function. When the insertion amount or eccentricity that exceeds the allowable range is detected, it can give the inspection personnel quick feedback through the digital display device.

[0034] The implementation of this technical solution has significantly improved the inspection quality and work efficiency of aircraft fuel pipe flanges, thereby improving assembly efficiency and aircraft safety. BRIEF DESCRIPTION OF THE DRAWINGS
