[0002] In the field of aviation technology, electric control locks, as supporting products of aircraft side rails, play a crucial role. They are mainly used for restraining and releasing container, plate, cargo platform and other container equipment along the flight direction during air transportation, ensuring the safety and stability of cargo transportation. With the continuous development of the aviation transportation industry, the performance and reliability requirements of electric control locks are also increasing. In order to ensure that electric control locks can work normally, the manufacturing technical specifications clearly stipulate strict acceptance test requirements and repair technical conditions, and the technical performance parameters of the products need to be checked regularly to meet the needs of overhaul detection and repair.
[0003] In related technologies, for electric control lock testing, conventional special testing equipment is often used. These devices are often designed for specific types or configurations of electric control locks. A common way is to customize special test fixtures and loading devices for a single configuration of electric control lock, and to apply a certain force to the electric control lock through manual operation or simple mechanical transmission to detect its basic locking and unlocking functions. Another way is to use simple sensors to detect part of the performance parameters of the electric control lock, but this detection method can only obtain limited information and cannot fully evaluate the performance of the electric control lock.

[0060] S32, adjust the driving assembly 31 to the unlocking state; S33, control the cylinder 28 to apply a pushing force of about 1200N to the telescopic shaft of the driving assembly 31, and if the displacement sensor 27 detects that the telescopic shaft of the driving assembly 31 fails to adjust to the fully retracted state, control the cylinder 28 to reduce the force by 50N in turn until the telescopic shaft of the driving assembly 31 just reaches the retracted state. At this time, the pushing force applied by the cylinder 28 to the telescopic shaft of the driving assembly 31 is the maximum output force of the driving assembly 31.
[0061] In the above process, the temperature sensor 23 monitors the temperature of the driving motor in the driving assembly 31 in real time, and the test is paused when the surface temperature of the driving motor reaches 60±2℃, and the test is continued after the surface temperature of the driving motor returns to the ambient temperature.
[0062] The specific process of the stroke test of the driving assembly 31 is as follows: S41, fix the driving assembly 31 to the first tool 22a, fix the telescopic shaft of the driving assembly 31 to the second tool 24a, and adjust the position of the sliding piece 24 as needed.
[0063] S42, control the driving assembly to the locked state or the unlocked state, and the displacement sensor 27 records the numerical value of the position of the telescopic shaft of the cylinder 28 at this time as H1.
[0064] S43, control the cylinder 28 to apply maximum output force to the telescopic shaft of the drive assembly 31, and apply force to the unlocking (or locking) direction.
[0065] S44, when the telescopic shaft of the drive assembly 31 reaches the unlocking (or locking) position, the displacement sensor 27 records the value of the position of the telescopic shaft of the cylinder 28 at this time as H2. S45, the stroke is calculated as (H1-H2) taking a positive number.
[0066] The implementation principle of the drive test device in the embodiment of the application is that when the measured electric control lock 30 fails, the performance (such as driving force, stroke, response time, etc.) of the drive assembly 31 can be tested in a targeted manner, so that the fault source can be quickly and accurately located, and the efficiency and accuracy of fault diagnosis are improved.
[0067] The embodiment of the application discloses an electric control lock test device.
[0068] The electric control lock test device in the embodiment is connected with the drive test device to form the electric control lock test device, and in an actual product, the electric control lock test device and the drive test device can not be connected.
[0069] Figure 1 is a structural schematic view of a first angle of an electric control lock test device and a drive test device according to the embodiment of the application. Referring to Figure 1 The electric control lock test device comprises an electric control lock test device 10, a drive test device 20 and an industrial computer. The electric control lock test device 10 is used to measure the working voltage, working current, loading force and unlocking time of a measured electric control lock 30 under the condition of applying a loading force. The drive test device 20 is used to measure the holding force, maximum output force and stroke of the drive assembly of the measured electric control lock 30. The industrial computer is connected with the electric control lock test device 10 and the drive test device 20. The industrial computer is used to control the electric control lock test device 10 and the drive test device 20 to test the measured electric control lock 30. The industrial computer is also used to be connected with the measured electric control lock 30 to control the unlocking and locking of the measured electric control lock 30.
[0070] The implementation principle of the electric control lock test device according to the embodiment of the application is that the industrial computer as a control core can preset a test program, automatically control the operation of the electric control lock test device and the drive test device, collect all sensor data, perform data analysis and generate a report. This greatly reduces manual intervention and improves test efficiency and consistency.
[0071] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
