Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling joints, and in particular to a liquid cooling joint reliability testing device. Background Art

[0002] Liquid cooling quick connector is a kind of quick connector used to connect cooling water circuit, including male connector and female connector. The male connector is inserted into the female connector and fixed by the internal structure. When pulling out, the sheath of the female connector is pushed back, and the male connector and the female connector can be quickly separated.

[0003] This type of liquid-cooled joint needs to be tested after production is completed. The test content includes whether the male and female connectors cannot automatically lock during the insertion process, whether the male and female connectors cannot rebound and reset when pulled out, whether there is water leakage in the male and female connectors when the male connector is pulled out from the female connector under the water circuit pressure test state, and the wear of the internal sealing rings of the male and female connectors through continuous pressure plugging and unplugging tests.

[0004] For example, the patent with publication number CN220625735U specifically discloses a plug-in and pull-out test tool for liquid-cooled quick connectors. The male connector and the female connector of the liquid-cooled connector are fixed by using a male connector fixing seat and a female connector fixing seat, and then the main cylinder, the clamping cylinder, and the guide rod cylinder are used to drive the male connector and the female connector to simulate the plug-in and pull-out process, and the plug-in and pull-out test is performed, thereby improving the test effect and test efficiency of the liquid-cooled quick connector.

[0005] In the above patent, the device can quickly perform repeated plug-in and unplug tests on the male connector and the female connector by setting up two groups of test sockets. During the actual use of the liquid-cooled connector, due to the differences in manual installation, the relative positions (including rotation angles) of the male connector and the female connector may be different each time they are connected. Since this test device fixes the male connector and the female connector during the test, this difference cannot be reflected. Therefore, it is necessary to provide a liquid-cooled connector reliability test device to solve the above problem, so that the same connector can show different test results in multiple tests due to different installation positions.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0043] Embodiment 1: This embodiment specifically describes the basic structure and working principle of a liquid cooling joint reliability testing device, specifically:

[0044] like Figure 1-Figure 4 As shown, the present application provides a liquid cooling joint reliability testing device, including a testing mechanism 1, which is located in a production workshop of a liquid cooling joint processing plant and is used to test the liquid cooling joint after production, so as to test the fatigue and durability of the liquid cooling joint;

[0045] The test mechanism 1 includes a fixed platform 11, which is fixedly installed on the ground. A rotating assembly 2 is arranged on the top of the fixed platform 11. The rotating assembly 2 includes a first base 21. A rotating motor 22 is fixedly installed on the top of the first base 21. A rotating shaft 23 is connected to the output end of the rotating motor 22 through a coupling. The rotating assembly 2 also includes a second base 25. A through hole is arranged at the center of the second base 25. The other end of the rotating shaft 23 passes through the second base 25 and is suitable for rotating in the second base 25.

[0046] A first chuck 24 is fixedly installed at one end of the rotating shaft 23 away from the rotating motor 22. The first chuck 24 is a traditional three-jaw chuck with latch teeth, and the first chuck 24 is suitable for rotating under the drive of the rotating motor 22. A first joint 241 is arranged on one side of the top of the first chuck 24, and a connecting pipe (not shown in the figure) connected to the first joint 241 is arranged through the center of the first chuck 24. The female connector to be tested is suitable for being connected to the connecting pipe, and is suitable for being clamped and fixed by multiple groups of latch teeth on the first chuck 24 after installation. When testing, it is connected to the first joint 241 through an external water pipe, and the test liquid can be transported into the female connector through the connecting pipe.

[0047] At the same time, a propulsion assembly 3 is arranged on the side of the fixed platform 11 away from the rotating assembly 2, and the propulsion assembly 3 includes a cylinder 31, and the cylinder 31 is fixedly installed on the fixed platform 11. At the same time, a slide 32 is fixedly installed on the output end of the cylinder 31, and the slide 32 is slidably installed on the fixed platform 11, and the slide 32 is suitable for reciprocating on the fixed platform 11 under the drive of the cylinder 31;

[0048] At the same time, a second chuck 34 is installed on the side of the slide 32 away from the cylinder 31, and the second chuck 34 is used to clamp the male connector;

[0049] A second joint 35 is provided on the top of the slide 32, and a bellows 36 connected to the second joint 35 is provided inside the slide 32, and the other end of the bellows 36 is connected to the male connector inside the second chuck 34. When the test starts and the male connector is connected to the female connector, the water flow input by the female connector can be transmitted to the outside of the slide 32 through the bellows 36, thereby completing the water flow connectivity test.

[0050] When the test starts, firstly, the female connector and the male connector are placed in the first chuck 24 and the second chuck 34 respectively, and the test liquid is transported into the female connector through the first connector 241, and then the rotary motor 22 is started to rotate the female connector in the first chuck 24, and at the same time, the cylinder 31 is controlled to drive the male connector to move toward the female connector, so that the male connector and the female connector are connected to each other. At this time, the rotary motor 22 stops, and the test liquid is transported into the male connector through the female connector, and then the leakage between the male connector and the female connector can be tested by controlling the hydraulic pressure;

[0051] When the infusion test is completed, the male connector is separated from the female connector by the cylinder 31, and then the rotating motor 22 continues to drive the female connector to rotate, so that the relative position between the female connector and the male connector changes. At this time, the male connector can continue to be driven by the cylinder 31 to connect with the female connector, and this process is repeated, so that the female connector and the male connector are repeatedly connected at different positions, so as to perform a connection test, and observe whether the male and female connectors will leak water when the male connector is pulled out from the female connector, and the wear of the internal sealing rings of the male and female connectors is tested repeatedly under pressure.

[0052] Embodiment 2: After multiple tests, some wear may occur on both the male connector and the female connector, and the male and female connectors may fail to lock automatically during the plugging process, and the male and female connectors may fail to rebound and reset when pulled out. At this time, the test liquid at the male and female connectors may flow out from the connection and contaminate the test bench. For this reason, improvements are made to the test mechanism 1, specifically:

[0053] like Figure 5As shown, a water pool 4 is arranged on the fixed platform 11, and the water pool 4 is arranged between the rotating component 2 and the propulsion component 3. At the same time, a accommodating cavity 41 is arranged on the fixed platform 11 at the bottom of the water pool 4, and a collecting bucket 42 is arranged in the accommodating cavity 41. The collecting bucket 42 is connected to the water pool 4 through a water pipe. When the male connector and the female connector are separated from each other, if water seepage occurs in the male and female connectors, the seeped test liquid will be received and recovered by the water pool 4.

[0054] like Figure 5-Figure 8 As shown, in order to enable the test fluid remaining inside the male connector to be quickly discharged during the retreat process after the test is completed, a rotating part 33 is provided on the side of the slide 32 away from the cylinder 31, and the rotating part 33 includes a first plate 331, the first plate 331 is fixedly installed on one side of the slide 32, a rotating shaft is rotatably installed at the bottom of the first plate 331, and a second plate 332 is fixedly installed on the rotating shaft, and a second chuck 34 is installed on the side of the second plate 332 away from the first plate 331, and when installed, the bellows 36 passes through the first plate 331 and the second plate 332;

[0055] At the same time, an adjustment mechanism 5 is also provided on the propulsion assembly 3, and the adjustment mechanism 5 is used to control the male connector to rotate a certain angle toward the water pool 4 when retreating, so as to discharge the test liquid;

[0056] The adjusting mechanism 5 includes a connecting shaft 51, and a shaft sleeve (not shown in the figure) is fixedly installed on one side of the rotating shaft at the bottom of the first plate 331. The connecting shaft 51 is suitable for being fixedly connected to the shaft sleeve to drive the second plate 332 to rotate. At the same time, a support platform 53 is extended and arranged on one side of the bottom of the slide 32. The support platform 53 is rotatably connected to the connecting shaft 51 and is used to provide support for the connecting shaft 51.

[0057] At the same time, a rectangular block 52 is laterally arranged on one side of the connecting shaft 51, and the block 52 has a first end and a second end, wherein one side of the first end is fixedly connected to the connecting shaft 51, and at the same time, a guide column 54 is fixedly installed on the second end of the block 52 away from the connecting shaft 51, and a moving block 55 is provided at the front end of the guide column 54, and the moving block 55 is made of rubber material and has a certain elasticity, and the moving block 55 is used to drive the connecting shaft 51 to rotate.

[0058] like Figure 8-Figure 12 As shown, an adjustment plate 6 is provided on one side of the fixed platform 11, and the adjustment plate 6 has a plurality of channels, including a first channel 61. In an initial state, the moving block 55 is located in the first channel 61, and this position is defined as an initial position. When the moving block 55 is located in the initial position in the first channel 61, the height of the second end of the clamping block 52 is less than the height of the first end.

[0059] The first channel 61 is provided with a second channel 62 on one side away from the initial position. The second channel 62 is an extension of the first channel 61. The bottom height of the first channel 61 is higher than the bottom height of the second channel 62. When the moving block 55 moves from the first channel 61 to the second channel 62, it cannot return from the second channel 62 to the first channel 61.

[0060] When the male connector and the female connector need to be tested, the cylinder 31 drives the male connector to move toward the female connector, and the moving block 55 moves from the first channel 61 to the second channel 62. At the same time, since the male connector and the female connector need to be plugged and unplugged, when the cylinder 31 drives the male connector to perform plugging and unplugging and leakage testing, the moving block 55 only moves horizontally in the second channel 62, and will not return from the second channel 62 to the first channel 61;

[0061] At the same time, in order to enable the male connector to quickly pour out the test liquid inside after the test is completed, a third channel 63 is provided on one side of the second channel 62 to extend upward and tilt, and the third channel 63 is connected to the second channel 62. When the test is completed, the cylinder 31 will drive the male connector to retract, and the moving block 55 located in the second channel 62 will enter the third channel 63. Since the third channel 63 is inclined, the center position of the moving block 55 will continue to rise under the guidance of the third channel 63, driving the second end of the block 52 to continue to rise upward. At this time, the height of the second end gradually exceeds the height of the first end, thereby driving the connecting shaft 51 to rotate, so that the first plate 331 and the second plate 332 are separated from each other, and driving the male connector in the second chuck 34 to move toward the direction of the pool 4. At this time, the test liquid remaining in the male connector will directly flow into the pool 4, which is convenient for subsequent cleaning and recycling.

[0062] At the same time, a fourth channel 64 is extended on one side of the third channel 63 away from the second channel 62. The fourth channel 64 is a mirror image of the third channel 63. When the male connector continues to retreat under the drive of the cylinder 31, the moving block 55 will move from the third channel 63 to the fourth channel 64. Since the fourth channel 64 is in the opposite direction to the third channel 63, the center position of the moving block 55 will continue to drop under the guidance of the fourth channel 64. At this time, the second end of the clamping block 52 will move downward under the drive of the moving block 55, so that the height of the second end is gradually smaller than the height of the first end, thereby driving the connecting shaft 51 to rotate in the opposite direction, so that the first plate 331 and the second plate 332 are merged with each other, so that the male connector in the second chuck 34 is returned to the right position, which is convenient for the next installation.

[0063] The fourth channel 64 is connected to the first channel 61, and a step block 65 is provided at the connection between the two. The height of the step block 65 is higher than the bottom height of the groove of the first channel 61, and a bevel is provided on the side of the step block 65 facing the fourth channel 64, so that the moving block 55 is suitable for moving from the fourth channel 64 to the initial position of the first channel 61 through the bevel of the step block 65 when retreating. When the moving block 55 moves forward driven by the cylinder 31, it will be blocked by the other side of the step block 65, so that the moving block 55 can only move from the first channel 61 to the second channel 62, but cannot directly enter the fourth channel 64.

[0064] When the test starts, the male connector is adapted to continuously move toward the female connector under the drive of the cylinder 31 and perform fatigue testing. When retreating after the test is completed, the male connector will rotate under the drive of the adjustment mechanism 5, so that the residual water in the male connector can be quickly poured into the pool 4. Then, with the continuous movement of the cylinder 31, the male connector will return to the correct position and prepare for the next test.

[0065] In summary, the device sets up the testing mechanism 1 so that the male connector and the female connector can quickly perform fatigue testing and leakage testing. At the same time, by setting the adjusting mechanism 5, the male connector can be tilted to a certain extent after the test is completed, so that the test liquid remaining in the male connector can be quickly discharged, which is convenient for the next test work and improves the practicality of the device.

[0066] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
