Description

Technical Field

[0001] This application relates to the field of mechanical component testing technology, and in particular to a liquid-cooled quick connector insertion and removal testing device. Background Technology

[0002] As a key component in liquid cooling systems, the reliability of liquid-cooled quick-connect couplings, their sealing performance, and service life directly affect the stable operation of the entire system. Current technologies typically employ single-station testing equipment to test the insertion and removal performance of liquid-cooled quick-connect couplings, testing only one set of male and female couplings at a time. However, in practical applications, a liquid cooling system often contains multiple sets of liquid-cooled quick-connect couplings, which may need to be validated under different operating conditions or batches. Single-station testing equipment is not only inefficient and unable to meet the needs of batch testing, but also suffers from poor consistency in results between different test batches due to the lack of precise simulation and unified control of the testing process. This makes it impossible to comprehensively and efficiently evaluate the overall performance of liquid-cooled quick-connect couplings in real-world application scenarios. Summary of the Invention

The Z-axis offset structure and the Z-axis offset sensor are electrically connected to the main electrical control box. The Z-axis offset sensor is configured to provide real-time feedback of the second actual value of the positional offset between the male and female quick-connect couplings in the Z-axis direction.

[0011] Optionally, in some embodiments of this application, the insertion and removal testing mechanism further includes a fluid supply component, which is configured to supply a fluid medium with a preset pressure value to the quick-connect male and female connectors in the inserted state, so as to simulate the medium environment when the liquid-cooled quick-connect is actually working, and to detect the sealing parameters of a corresponding set of liquid-cooled quick-connects.

[0012] Optionally, in some embodiments of this application, the insertion / removal testing device further includes a fluid replenishment tank, and the fluid supply assembly includes a fluid delivery pipeline, a pressure reducing valve, a pressure sensor, and a flow calibration column, wherein...

[0014] The liquid-cooled quick-connect fitting insertion and removal testing equipment provided in this application, through the aforementioned structural design, constructs an efficient and controllable parallel testing platform by setting up a main electrical control box and at least two insertion and removal testing mechanisms electrically connected to the main electrical control box. Firstly, the multi-station design allows for simultaneous insertion and removal testing of at least two sets of liquid-cooled quick-connect fittings, significantly improving testing efficiency and meeting the needs of mass production testing. Secondly, through unified control of the main electrical control box, each insertion and removal testing mechanism can simulate the actual insertion and removal operations of the male and female quick-connect fittings according to preset collaborative or independent modes, ensuring the consistency of test conditions and the accuracy of test results. This allows for a more realistic simulation of the actual operating state of the liquid-cooled quick-connect fitting under complex working conditions, comprehensively evaluating the insertion and removal performance parameters and service life of the quick-connect fitting.

[0019] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0021] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1 to 3 As shown, in one embodiment, this application provides a liquid-cooled quick-connect fitting test device 1. The liquid-cooled quick-connect includes a male quick-connect connector 2 and a female quick-connect connector 3. The fitting test device 1 includes a device frame 10, a main electrical control box 20, and at least two fitting test mechanisms 30. The main electrical control box 20 is installed in the device frame 10 and is electrically connected to each of the fitting test mechanisms 30. At least two fitting test mechanisms 30 are respectively installed in the device frame 10. Each fitting test mechanism 30 is configured to simulate the fitting and unfitting operation of the corresponding male quick-connect connector 2 and female quick-connect connector 3 according to a preset method under the control of the main electrical control box, in order to test the fitting and unfitting performance parameters of the corresponding set of liquid-cooled quick-connect connectors.

[0023] It should be noted that the liquid-cooled quick-connect fitting test equipment 1 of this application embodiment is mainly applied to the research and development verification, factory quality inspection, or life testing scenarios of liquid-cooled quick-connect products in the fields of liquid-cooled servers, energy storage equipment, and new energy vehicles. The fitting test equipment 1 is equipped with at least two fitting test mechanisms 30, which can operate independently to perform corresponding fitting tests on at least two sets of liquid-cooled quick-connects, thereby greatly improving the fitting test efficiency. Furthermore, different fitting test mechanisms 30 can simultaneously perform fitting tests on the same model of liquid-cooled quick-connects, or simultaneously perform fitting tests on different models of liquid-cooled quick-connects, and can also set different test parameters for comparative testing of the same model of liquid-cooled quick-connects, greatly improving testing flexibility and efficiency. The aforementioned main electrical control box 20 can specifically be a programmable logic controller (PLC) or an industrial computer, whose internally preset or editable test control program is used to precisely coordinate and control the action sequence and operating parameters of each functional component in each fitting test mechanism 30 in real time, realizing the automated testing process of each fitting test mechanism 30.

[0024] In this way, the liquid-cooled quick-connect fitting insertion and removal testing equipment 1 of this application embodiment, through the above-described structural configuration, constructs an efficient and controllable parallel testing platform by setting up a main electrical control box 20 and at least two insertion and removal testing mechanisms 30 electrically connected to the main electrical control box 20. Firstly, the multi-station design allows for simultaneous insertion and removal testing of at least two sets of liquid-cooled quick-connect fittings, significantly improving testing efficiency and meeting the needs of mass production testing. Secondly, through the unified control of the main electrical control box 20, each insertion and removal testing mechanism 30 can simulate the actual insertion and removal operation of the male and female quick-connect fittings according to a preset collaborative or independent mode, ensuring the consistency of testing conditions and the accuracy of test results. This allows for a more realistic simulation of the actual operating state of the liquid-cooled quick-connect fitting under complex working conditions, comprehensively evaluating the insertion and removal performance parameters and service life of the quick-connect fitting.

[0025] In some examples, such as Figure 2 and Figure 3 As shown, the insertion / removal testing mechanism 30 includes a fixed mold assembly 31 and an insertion / removal driving assembly 32. The fixed mold assembly 31 is configured to clamp and fix the quick-connect female head 3. The insertion / removal driving assembly 32 is disposed opposite to the fixed mold assembly 31 and is configured to clamp and fix the quick-connect male head 2, and drive the quick-connect male head 2 to move along the X-axis direction, so that the quick-connect male head 2 and the quick-connect female head 3 can perform corresponding insertion / removal actions. The X-axis direction is the axial direction of the quick-connect male head 2 (i.e., the axial direction of the quick-connect male head 2). Figure 2(In the direction indicated by the middle arrow X). Thus, by fixing the quick-connect male connector 2 and quick-connect female connector 3 to their respective components, and precisely driving the quick-connect male connector 2 to move axially by the insertion / extraction drive component 32, the insertion / extraction process of the liquid-cooled quick-connect in actual use can be accurately simulated, ensuring the stability and repeatability of the insertion / extraction action, and providing a reliable basis for subsequent insertion / extraction force measurement and life test.

[0026] It should be noted that the relative positions of the fixed mold assembly 31 and the plug-in drive assembly 32 in this example can be adjusted according to testing requirements to accommodate liquid-cooled quick connectors of different specifications and sizes, thereby improving the versatility and adaptability of the equipment.

[0027] In some examples, such as Figure 2 and Figure 3 As shown, the fixed mold assembly 31 includes a first positioning seat 311. The first positioning seat 311 has a first positioning groove (not shown) at one end facing the insertion / removal drive assembly 32. The first positioning groove is configured to clamp and fix the quick-connect female connector 3. The insertion / removal drive assembly 32 includes a second positioning seat 321 and an insertion / removal drive structure 322 that drives the second positioning seat 321 to move along the X-axis. The second positioning seat 321 has a second positioning groove (not shown) at one end facing the fixed mold assembly 31. The second positioning groove is configured to clamp and fix the quick-connect male connector 2. Thus, by setting a dedicated positioning groove (i.e., the first positioning groove or the second positioning groove) to clamp and fix the corresponding quick-connect female connector 3 or quick-connect male connector 2, the positional stability and repeatability of the liquid-cooled quick-connect during testing can be ensured, avoiding test errors caused by improper clamping. Furthermore, the shape of the positioning groove (i.e., the first positioning groove or the second positioning groove) can be customized according to the shape of the corresponding quick-connect female connector 3 or quick-connect male connector 2 to adapt to the insertion / removal testing requirements of different types and specifications of liquid-cooled quick-connects.

[0028] It should be noted that, in this example, the first and second positioning slots may be further equipped with elastic clamping mechanisms or quick clamps to facilitate the quick assembly and disassembly of the corresponding quick connector female head 3 or quick connector male head 2, thereby further improving the efficiency of the corresponding insertion and removal tests.

[0029] In some examples, such as Figure 2 and Figure 3As shown, the insertion / removal drive structure 322 includes a thrust sensor (not shown), a ball screw, an insertion / removal moving seat that engages with the ball screw's rolling helix, and a servo motor that drives the ball screw to rotate, causing the insertion / removal moving seat to move back and forth relative to the ball screw. A second positioning seat 321 is fixed on the insertion / removal moving seat. The servo motor and the thrust sensor are electrically connected to the main control box 20. The main control box 20 is configured to collect the axial force value generated by the insertion / removal action through the thrust sensor, and when the axial force value is less than or equal to a preset force threshold, obtain the axial force value as the insertion / removal force parameters for a corresponding set of liquid-cooled quick connectors. When the axial force value is greater than the preset force threshold, control the corresponding servo motor to stop the corresponding insertion / removal action. Thus, by using a servo motor to drive the ball screw, high-precision and high-stability linear motion can be achieved, ensuring the smoothness of the insertion / removal action and the accuracy of position control. The thrust sensor can monitor the axial force generated during the insertion / removal process in real time, providing accurate data for obtaining the insertion / removal force parameters. Meanwhile, when abnormally high insertion and extraction force is detected, the main electrical control box 20 can promptly control the servo motor to stop operating, effectively protecting the quick connector and test equipment from damage.

[0030] It should be noted that the preset force threshold in this example can be set according to the specifications and testing requirements of the liquid-cooled quick connector to adapt to the testing needs of different products. The axial force data collected by the thrust sensor in this example can be recorded and stored in real time for subsequent insertion and extraction force analysis and life assessment. In addition, the thrust sensor in this example can preferably be installed in the second positioning slot in actual layout to more directly sense the axial load transmitted to the male quick connector 2 during insertion and extraction.

[0031] In some examples, such as Figure 2 and Figure 3 As shown, the insertion / removal test mechanism 30 also includes an offset simulation component 33. The offset simulation component 33 is drivenly connected to at least one of the first positioning seat 311 and the second positioning seat 321. The offset simulation component 33 is configured to drive at least one of the first positioning seat 311 and the second positioning seat 321 to perform offset movement in at least one direction to simulate the relative positional offset between the quick-connect male connector 2 and the quick-connect female connector 3 in a non-aligned state. In this way, by setting the offset simulation component 33, it is possible to simulate non-ideal alignment states such as axial offset and angular deviation that may occur during the actual installation and use of the liquid-cooled quick connector, making the test conditions closer to the actual working conditions, thereby more comprehensively evaluating the insertion / removal performance and adaptability of the liquid-cooled quick connector under complex conditions.

[0032] It should be noted that the offset simulation component 33 can be set with multiple degrees of freedom for offset motion, including linear offset and angular offset, to simulate various possible misalignment situations. The offset amount can be set according to the actual application scenario to test the insertion and extraction performance of the liquid-cooled quick connector under different offset levels.

[0033] In some examples, such as Figure 2 and Figure 3 As shown, the offset simulation component 33 includes a Y-axis offset structure 331 and a Y-axis offset sensor (not shown). The Y-axis offset structure 331 is driven to either the first positioning seat 311 or the second positioning seat 321 to drive the first positioning seat 311 or the second positioning seat 321 to move in the Y-axis direction (i.e., Figure 2 The offset movement (in the direction indicated by the middle arrow Y) causes a first preset positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Y-axis direction, which is perpendicular to the X-axis direction. The Y-axis offset structure 331 and the Y-axis offset sensor are electrically connected to the main control box 20. The Y-axis offset sensor is configured to provide real-time feedback of the first actual value of the positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Y-axis direction. The main control box 20 is configured to perform closed-loop control of the Y-axis offset structure 331 based on the first actual value and the first preset value to ensure that the Y-axis offset error is within the first preset accuracy range. Thus, by setting the Y-axis offset structure 331 and the Y-axis offset sensor, and adopting a closed-loop control method, the offset in the Y-axis direction can be precisely controlled, ensuring the accuracy and repeatability of the offset. This accurately simulates the misalignment of the liquid-cooled quick-connect connector in the Y-axis direction, providing reliable offset conditions for insertion and removal performance testing.

[0034] It should be noted that the first preset accuracy range in this example can be set according to the test requirements, and is usually controlled within ±0.01mm to ensure the accuracy of offset control. Furthermore, the Y-axis offset structure 331 in this example can specifically be a conventional precision linear module or a piezoelectric ceramic actuator.

[0035] In some examples, such as Figure 2 and Figure 3 As shown, the offset simulation component 33 includes a Z-axis offset structure (not shown) and a Z-axis offset sensor (not shown). The Z-axis offset structure is driven by either the first positioning seat 311 or the second positioning seat 321 to drive the first positioning seat 311 or the second positioning seat 321 to move in the Z-axis direction (i.e., Figure 2The offset movement (in the direction indicated by the arrow Z) causes a second preset positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Z-axis direction, which is perpendicular to the plane containing both the X and Y axes. The Z-axis offset structure and the Z-axis offset sensor are electrically connected to the main control box 20. The Z-axis offset sensor is configured to provide real-time feedback of the second actual value of the positional offset between the male quick-connect connector 2 and the female quick-connect connector 3 in the Z-axis direction. The main control box 20 is configured to perform closed-loop control of the Z-axis offset structure based on the second actual value and the second preset value to ensure that the Z-axis offset error is within the second preset accuracy range. Thus, by setting up the Z-axis offset structure and the Z-axis offset sensor, and employing closed-loop control, the offset in the Z-axis direction can be precisely controlled, ensuring the accuracy and repeatability of the offset. This accurately simulates the misalignment of the liquid-cooled quick-connect connector in the Z-axis direction, providing more comprehensive offset conditions for insertion and removal performance testing.

[0036] It should be noted that the second preset accuracy range in this example can also be set according to test requirements, and is usually controlled within ±0.01mm to maintain high precision in offset control. Furthermore, the Z-axis offset structure in this example can be a conventional precision linear module or a piezoelectric ceramic actuator.

[0037] In some examples, such as Figure 2 and Figure 3 As shown, the offset simulation component 33 includes a rotation offset structure (not shown) and an angle offset sensor (not shown). The rotation offset structure is driven by the first positioning seat 311 or the second positioning seat 321 to drive the first positioning seat 311 or the second positioning seat 321 to rotate and offset, thereby generating a third preset angle offset between the quick-connect male connector 2 and the quick-connect female connector 3. The rotation offset structure and the angle offset sensor are electrically connected to the main control box 20. The angle offset sensor is set to provide real-time feedback of the third actual value of the angle offset between the quick-connect male connector 2 and the quick-connect female connector 3. The main control box 20 is set to perform closed-loop control of the rotation offset structure based on the third actual value and the third preset value to ensure that the angle offset error is within the third preset accuracy range. In this way, by setting the rotation offset structure and the angle offset sensor and adopting a closed-loop control method, the angle offset can be accurately controlled, simulating the angle misalignment that may occur in the liquid-cooled quick connector under installation deviation or vibration environment, thereby more comprehensively evaluating the insertion and removal performance and sealing reliability of the liquid-cooled quick connector under complex working conditions.

[0038] It should be noted that the third preset accuracy range in this example can be set according to the test requirements, and is usually controlled within ±0.1° to ensure the accuracy of angular offset control. Furthermore, the rotational offset structure in this example can specifically be a conventional precision rotary table or a worm gear mechanism.

[0039] In some examples, such as Figure 2 and Figure 3 As shown, the insertion / extraction test mechanism 30 also includes a fluid supply component 34. The fluid supply component 34 is configured to supply a fluid medium with a preset pressure value to the quick-connect male connector 2 and quick-connect female connector 3 in the inserted state, simulating the media environment during actual operation of the liquid-cooled quick-connect, to detect the sealing parameters of the corresponding set of liquid-cooled quick-connects. Thus, by introducing the fluid supply component 34, the fluid pressure and media environment during actual operation of the liquid-cooled quick-connect can be simulated simultaneously with the insertion / extraction mechanical performance test, allowing for online detection of the sealing performance of the liquid-cooled quick-connect. This helps to evaluate the sealing reliability of the liquid-cooled quick-connect during dynamic insertion / extraction and under static pressure holding conditions, identify potential leakage problems, and thus more comprehensively evaluate the overall performance of the liquid-cooled quick-connect.

[0040] It should be noted that the fluid medium in this example can be selected according to the actual application scenario, such as deionized water, coolant, or compressed air. The preset pressure value can simulate the working pressure of the liquid cooling system for pressure decay testing or leakage rate testing.

[0041] In some examples, such as Figure 2 and Figure 3As shown, the insertion / removal test device 1 also includes a fluid replenishment tank 40. The fluid supply assembly 34 includes a fluid delivery pipeline 341, a pressure reducing valve 342, a pressure sensor 343, and a flow calibration column 344. The fluid delivery pipeline 341 connects the fluid replenishment tank 40 to a corresponding set of liquid-cooled quick-connect couplings. The fluid delivery pipeline 341 is configured to supply a fluid medium with a preset pressure value to the male and female quick-connect couplings 2 and 3 in the inserted state. The pressure reducing valve 342 is installed in the fluid delivery pipeline 341 and is configured to adjust and stabilize the fluid pressure within the corresponding fluid delivery pipeline 341 to the test value. The pressure sensor 343 is installed in the fluid delivery pipeline 341 and is configured to monitor the fluid pressure within the corresponding fluid delivery pipeline 341 in real time. The flow calibration column 344 is installed in the fluid delivery pipeline 341 and is configured to record changes in the fluid flow rate within the fluid delivery pipeline 341. The main control box 20 is also electrically connected to the pressure reducing valve 342, the pressure sensor 343, and the flow calibration column 344. Furthermore, the main control box 20 is configured to combine data from the pressure sensor 343 and the flow calibration column 344 to comprehensively determine the sealing parameters of a corresponding set of liquid-cooled quick-connect fittings. Thus, by setting up a fluid supply assembly 34 including the pressure reducing valve 342, the pressure sensor 343, and the flow calibration column 344, and cooperating with the main control box 20 for data acquisition and analysis, accurate testing of the sealing performance of the liquid-cooled quick-connect fittings can be achieved. The pressure reducing valve 342 ensures stable test pressure, the pressure sensor 343 monitors pressure changes in real time to determine if pressure decay exists, and the flow calibration column 344 records minute flow rate changes to calculate the leakage rate. By integrating this data, the main control box 20 can accurately determine whether the sealing performance of the quick-connect fitting is qualified and assess its long-term sealing stability.

[0042] It should be noted that, to achieve the electrical connection between the flow calibration column 344 and the main electrical control box 20 in this example, a flow sensor can be integrated internally or externally connected to the flow calibration column. This flow sensor converts the corresponding flow signal into an electrical signal, which is then transmitted to the main electrical control box 20. Based on the received electrical signal and a preset algorithm or calibration curve, the main electrical control box 20 can calculate the specific liquid leakage amount. Simultaneously, according to preset test standards, it can automatically determine the sealing test results and generate a test report. Furthermore, the flow calibration column 344 itself can also be a graduated transparent glass tube with an internal float, facilitating visual observation and manual recording by the operator.

[0043] In some examples, such as Figure 2 and Figure 3As shown, the insertion / removal testing mechanism 30 also includes a latch unlocking mechanism 35. The latch unlocking mechanism 35 includes two latch clamping blocks 351, a clamping drive cylinder 352 that drives the two latch clamping blocks 351 to close or open, and an unlocking drive cylinder 353 that drives the two latch clamping blocks 351 to move along the X-axis. The two latch clamping blocks 351 are positioned opposite each other on both sides of the latch of the quick-connect female connector 3, which is fixed to the corresponding fixed mold assembly 31. Thus, by providing the latch unlocking mechanism 35, automated insertion / removal testing of liquid-cooled quick-connect connectors with self-locking latches can be achieved. During the insertion and removal process, when it is necessary to separate the male quick connector 2 and the female quick connector 3, the clamping drive cylinder 352 drives the two latching blocks 351 to close, clamping the latches on the female quick connector 3. Then, the unlocking drive cylinder 353 drives the two latching blocks 351 to move along the X-axis (i.e., away from the male quick connector 2), thereby simulating the action of manually pressing or pulling the latches and achieving automatic unlocking. This realizes fully automatic testing of liquid-cooled quick connectors with locking mechanisms, without manual intervention, improving testing efficiency and automation level.

[0044] It should be noted that the shape of the latching block 351 in this example can be customized according to the specific structure of the quick connector female 3 latch to ensure the reliability of the clamping and to prevent damage to the latch. The timing of the actions of the clamping drive cylinder 352 and the unlocking drive cylinder 353 is precisely controlled by the main electrical control box 20 to simulate the real unlocking process.
