Description

Technical Field

[0001] This invention relates to the field of automation control technology, specifically to a plug-in durability testing device based on UQD metal quick-connect connectors. Background Technology

[0002] UQD's fully automated insertion and removal durability testing device for metal quick-connect fittings simulates and optimizes manual insertion and removal actions through a high-precision mechanical clamping mechanism. It can stably clamp the fitting under test and achieve precise alignment and cyclic insertion and removal with the air intake channel. Its core innovation lies in the integration of functional modules such as floating alignment, axial pre-tightening seal enhancement, and real-time gap monitoring. It can not only perform standardized durability tests, but also actively compensate for assembly errors and simulate pre-stress under real working conditions. Thus, under unattended conditions, it can efficiently and accurately evaluate the insertion and removal life, sealing reliability, and performance degradation law of the fitting, providing reliable data support that surpasses traditional manual testing for product quality control and design optimization.

[0003] The fully automated insertion and removal durability testing device for UQD metal quick-connect fittings uses a mechanical gripping mechanism to grasp the UQD fitting under test in an adaptive centering manner and initially align it with a fixed air intake channel. Under program control, the device performs high-speed, uniform reciprocating insertion and removal motions. Integrated sensors monitor and record in real time the axial force curve, micro-gap of the sealing surface, and pressure changes in the test air path for each insertion and removal. When a preset leakage threshold, abnormal force value, or the set number of cycles is detected, the system automatically determines that the test is terminated and generates a complete performance degradation report. The entire process requires no manual intervention, ensuring high repeatability and high accuracy of the test.

[0004] During the fixing process of the female end connector, the clamping force and centering angle applied by the operator are subjective and fluctuate, making it difficult to accurately control the initial contact pressure between the connector and the air intake channel. The degree of contact between the sealing rubber ring and the female end connector is different, the sealing ring is undercompressed, and there is a gap between the sealing rubber ring and the female end connector, which seriously affects the accuracy of the test results.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figures 1 to 8 According to a preferred embodiment of the present invention, a plug-in durability testing device based on a UQD metal quick-connect connector will be described in detail below. It includes a processing platform 1, on the upper surface of the processing platform 1, a plurality of base plates 11 are arranged in a linear array, and a top plate 13 is fixedly connected above each of the plurality of base plates 11 by a plurality of connecting rods. A guide plate 12 is arranged between the top plate 13 and the base plates 11. The guide plate 12 is sleeved on the surface of the plurality of connecting rods. A female end connector frame 14 is arranged inside the top plate 13. A ventilation groove is opened inside the female end connector frame 14. A storage groove is opened on the inner wall below the ventilation groove. An electric telescopic rod 16 is fixedly connected to the upper surface of the base plates 11. The output shaft of the electric telescopic rod 16 passes through the guide plate 12 and is located above the guide plate 12. One end of the output shaft of the electric telescopic rod 16 is fixedly connected to a male end connector frame 15. Under the restriction of the guide plate 12, the vibration caused by external influence during the upward sliding of the male end connector frame 15 driven by the output shaft of the electric telescopic rod 16 is reduced. The male connector frame 15 is provided with a screw assembly for fixing the male connector, and the lower surface of the top plate 13 is provided with a clamping mechanism for clamping the female connector inside the female connector frame. The male connector is fixed by the screw assembly and the female connector is fixed by the clamping mechanism. The screw and the clamping mechanism are aligned to ensure that the male connector and the female connector are aligned for insertion and removal. A lifting mechanism is provided on one side of the clamping mechanism to ensure that the female connector fits against the inner wall of the female connector frame 14.

[0021] Before the durability test of the quick-connect connector, the female connector is fixed inside the female connector frame 14 and the male connector is fixed inside the male connector frame 15. When the durability test is performed, the output shaft of the electric telescopic rod 16 drives the male connector to slide towards the female connector and extend into the female connector, and then drives the male connector to detach from the female connector. This process is repeated, and the insertion and removal durability of the male and female connectors is monitored in real time by the testing instrument.

[0022] like Figure 2 and Figure 3 In the process, the upper surface of the processing platform 1 is fixedly connected to the debugging component 2. The top of the female connector frame 14 is fixedly connected to the debugging component 2 via a connecting pipe 21. The female connector frame 14 has a ventilation groove inside, and a storage groove is provided on the inner wall below the ventilation groove. A sealing rubber ring 64 is snapped between the ventilation groove and the storage groove. The upper surface of the male connector frame 15 has a connector fixing groove 22. A power mechanism is provided below the top plate 13. The debugging component injects gas or liquid into the female connector frame 14 through the connecting pipe 21. The gas or liquid enters the female connector through the ventilation groove. The insertion and removal wear of the male connector and the female connector is determined based on the sealing condition of the male connector and the female connector.

[0023] When fixing the male connector, place the male connector inside the connector fixing groove 22, and push the male connector toward the center line of the fixing groove 2 through the screw assembly until the center line of the male connector is aligned with the center line of the connector fixing groove 22, and clamp and fix the male connector through the screw assembly.

[0024] like Figure 4In the power mechanism, there are two side connecting blocks 3 symmetrically fixedly connected to the lower surface of the top plate 13. A top lead screw 32 is rotatably connected between the two side connecting blocks 3. The two ends of the top lead screw 32 pass through the side connecting blocks 3 adjacent to it. A power motor 33 is fixedly connected to the side connecting block 3 away from the top lead screw 32. The output shaft of the power motor 33 is fixedly connected to one end of the top lead screw 32. Two power sliders 31 are symmetrically connected to the surface of the top lead screw 32 by sliding threads. Both ends of the top lead screw 32 are threaded. The output shaft of the power motor 33 drives the top lead screw 32 to rotate. The top plate 13 is fixedly connected to a top guide rail 34, and two sliding blocks 35 are symmetrically slidably connected to the surface of the top guide rail 34. A central connecting plate 36 is fixedly connected between the sliding blocks 35 and the adjacent sliding blocks 31. The sliding blocks 35 slide on the surface of the top guide rail 34, thereby driving the central connecting plate 36 to slide stably along the surface of the top guide rail 34. Initially, the sliding blocks 31 are located at both ends of the top lead screw 32, and at this time the clamping mechanism is away from the female end connector frame 14.

[0025] When fixing the female connector, the female connector is placed inside the female connector frame 14. With the operator's support, the upper end of the female connector contacts the upper inner wall of the female connector frame 14. The output shaft of the power motor 33 drives the top lead screw 32 to rotate, and the two power sliders 31 are driven to move closer to each other through the surface thread. This pulls the two central connecting plates 36 along the top guide rail 34 toward the female connector frame 14, thereby providing power to the clamping mechanism and fixing the female connector.

[0026] like Figure 5The clamping mechanism includes an extension guide block 42 fixedly connected to the lower surface of the central connecting plate 36. A sliding push plate 4 is slidably connected to the lower surface of the central connecting plate 36. A guide rail groove 41 is formed on the upper surface of the sliding push plate 4. The extension guide block 42 extends into the interior of the guide rail groove 41. A contact spring 43 is fixedly connected to the inner wall of the guide rail groove 41. The contact spring 43 is fixedly connected to the extension guide block 42. The sliding push plate 4 slides stably below the central connecting plate 36 through the guide rail groove 41. Initially, the extension guide block 42 is located inside the end of the guide rail groove 41 away from the female end connector frame 14. The contact spring 43 is in its normal state. Two side limiting blocks 44 are symmetrically fixedly connected to the upper surface of the sliding push plate 4. Each of the two side limiting blocks 44 has a side opening that is close to each other. There is an ascending groove 45, and a top clamping block 48 is slidably connected between two side limiting blocks 44. The two top clamping blocks 48 have V-shaped grooves on their adjacent sides. The V-shaped grooves on both sides ensure that the female end connector is aligned with the center line of the female end connector frame 14 during the fixing process. Lifting blocks 47 are fixedly connected to both ends of the top clamping block 48. The lifting blocks 47 extend into the interior of the ascending groove 45. A side spring 46 is fixedly connected to the inner wall of the ascending groove 45. The side spring 46 is fixedly connected to the adjacent lifting block 47. The top clamping block 48 slides stably up and down along the ascending groove 45 under the action of the lifting block 47. Initially, the lifting block 47 is located at the lower end of the ascending groove 45, and the side spring 46 is in the normal state.

[0027] like Figure 5 In the middle, the lifting mechanism includes two bottom connecting blocks 5 symmetrically fixedly connected to the lower surface of the top clamping block 48. The two bottom connecting blocks 5 are rotatably connected to a roller 51 through a rotating shaft. The center connecting plate 36 is fixedly connected to a lifting block 52 on the side near the top clamping block 48. An adjustment mechanism is provided inside the female end connector frame 14. The lifting block 52 is provided with an inclined surface on the side near the top clamping block 48. The roller 51 is located on the sliding path of the inclined surface of the lifting block 52.

[0028] As the two center connecting plates 36 move closer to the female end connector frame 14 along the top guide rail 34, the extension guide block 42 pushes the sliding push plate 4 to slide synchronously through the contact spring 43, thereby driving the two top clamping blocks 48 to clamp and fix the female end connector. After the female end connector is fixed, the two top clamping blocks 48 cannot continue to slide under the resistance of the female end connector. At this time, the central connecting plate 36 continues to slide under the drive of the power slider 31. The extension guide block 42 slides along the inside of the guide rail groove 41. The contact spring 43 is compressed under the push of the extension guide block 42 and the resistance of the top clamping block 48. The lifting block 52 slides synchronously under the drive of the central connecting plate 36. The inclined surface of the lifting block 52 contacts the roller 51, thereby giving the roller 51 an upward thrust, which in turn pushes the top clamping block 48 to slide upward, causing the female end connector in the clamping state to slide upward synchronously, thereby improving the contact degree between the female end connector inlet and the sealing rubber ring 64 inside the female end connector frame 14. By driving the female end connector, which is in a clamped state, to slide upward, the gap between the female end connector inlet and the sealing rubber ring 64 inside the female end connector frame 14 is forcibly eliminated, so that the sealing rubber ring 64 is compressed to the designed optimal working range. Before the start of the test cycle, a sealing surface compaction operation is performed to ensure the consistency and optimality of the fit.

[0029] like Figure 6 and Figure 7 The adjustment mechanism includes a lifting groove 6 inside the top plate 13, a female end connector frame 14 slidably connected to the inside of the lifting groove 6, a pressure groove 61 on the inner wall of the lifting groove 6, a pressure plate 62 slidably connected inside the pressure groove 61, the pressure plate 62 being fixedly connected to the female end connector frame 14, a pressure spring 63 on the inner wall of the pressure groove 61, the pressure spring 63 being fixedly connected to the pressure plate 62, and a pressure mechanism inside the female end connector frame 14. By sliding the pressure plate 62 inside the pressure groove 61, the female end connector frame 14 is driven to slide stably up and down along the pressure groove 61. Initially, the pressure plate 62 is located at the lower end of the pressure groove 61, and the pressure spring 63 is in its normal state.

[0030] like Figure 7In the middle, the pressure mechanism includes two side adjustment grooves 7 symmetrically opened on the inner wall of the lifting groove 6. The side adjustment groove 7 has an inclined surface on the side away from the female end connector frame 14. The female end connector frame 14 has two symmetrically opened communicating grooves 76. The inner wall of the communicating groove 76 has a contraction groove 72. The contraction groove 72 passes through the female end connector frame 14 and communicates with the side adjustment groove 7. The inner wall of the contraction groove 72 has a contraction piston groove 73. The inner wall of the contraction groove 72 is slidably connected to a contact rod 71. One end of the contact rod 71 extends into the inner wall of the side adjustment groove 7. The inner piston 75 is slidably connected to the inner wall of the contraction piston groove 73. The inner piston 75 is fixedly connected to the contact rod 71. The inner wall of the contraction piston groove 73 is fixedly connected to a contraction spring 74. The contraction spring 74 is fixedly connected to the inner piston 75. Initially, the contact rod 71 is not in contact with the inclined surface of the side adjustment groove 7. At this time, the inner piston 75 is located in the inner wall of the contraction piston groove 73 near the side adjustment groove 7. At this time, the contraction spring 74 is in the normal state.

[0031] like Figure 8 In the middle, an annular groove 78 is provided below the sealing rubber ring 64, and two test grooves 77 are symmetrically provided on the inner wall of the annular groove 78. The two test grooves 77 are connected to the adjacent connecting grooves 76. A prompting mechanism is provided inside the female end connector frame 14. like Figure 7 The prompting mechanism includes a push-out groove 8 formed on the inner wall of the upper end of the connecting groove 76. The push-out groove 8 extends through the female end connector frame 14 to the outside of the female end connector frame 14. A push-piston groove 82 is formed on the inner wall of the push-out groove 8. A push-out rod 81 is slidably connected inside the push-piston groove 82. An extension piston 83 is slidably connected inside the push-piston groove 82. The extension piston 83 is fixedly connected to the push-out rod 81. A push-out spring 84 is fixedly connected to the inner wall of the push-piston groove 82. The push-out spring 84 is fixedly connected to the extension piston 83. Initially, the extension piston 83 is located inside the push-piston groove 82 near the end of the connecting groove 76. The push-out rod 81 retracts into the female end connector frame 14. At this time, the push-out spring 84 is in the normal state.

[0032] As the female end connector slides upward under the drive of the lifting mechanism, the gap between the sealing rubber ring 64 and the opening of the female end connector is eliminated by the resistance between the pressure spring 63 and the female end connector. As the female end connector continues to slide upward, the female end connector frame 14 slides upward synchronously under the push of the female end connector. During this process, the contact rod 71 slides up synchronously with the female end connector frame 14 and contacts the inclined surface of the side adjustment groove 7, thereby pushing the contact rod 71 to slide towards the connecting groove 76, thereby pushing the gas inside the contraction piston groove 73 into the connecting groove 76 through the inner piston 75. When there is a gap between the sealing rubber ring 64 and the opening of the female end connector, when the inner piston 75 pushes the gas inside the constricting piston groove 73 into the connecting groove 76, the gas cannot be discharged from the ejection groove 8 under the resistance of the extension piston 83 given by the ejection spring 84, and is discharged from the gap between the sealing rubber ring 64 and the opening of the female end connector through the test groove 77. At this time, the ejection rod 81 cannot be pushed out. When the sealing rubber ring 64 is tightly fitted with the opening of the female end connector, the inner piston 75 pushes the gas inside the constricting piston groove 73 into the connecting groove 76. The gas pushes the extension piston 83 to slide away from the connecting groove 76. The push spring 84 is compressed under the push of the extension piston 83, and the push rod 81 is pushed out of the female end connector frame 14 under the push of the extension piston 83. By observing the position of the push rod 81, it is determined whether there is a gap between the sealing rubber ring 64 and the opening of the female end connector. This avoids the problem that the vibration of insertion and removal during high-speed or long-cycle insertion and removal tests may cause gaps in the connection relationship of the fixed end, leading to pressure fluctuations or leakage and misjudgment in subsequent tests, thus improving the accuracy of subsequent tests.

[0033] Working principle: When fixing the female end connector, the female end connector is placed inside the female end connector frame 14. With the operator's support, the upper end of the female end connector contacts the upper inner wall of the female end connector frame 14. The output shaft of the power motor 33 drives the top lead screw 32 to rotate, and drives the two power sliders 31 to move closer to each other through the surface thread. This pulls the two central connecting plates 36 along the top guide rail 34 towards the female end connector frame 14, thereby providing power to the clamping mechanism and fixing the female end connector. As the female end connector slides upward under the drive of the lifting mechanism, the gap between the sealing rubber ring 64 and the opening of the female end connector is eliminated by the resistance between the pressure spring 63 and the female end connector. As the female end connector continues to slide upward, the female end connector frame 14 slides upward synchronously under the push of the female end connector. During this process, the contact rod 71 slides up synchronously with the female end connector frame 14 and contacts the inclined surface of the side adjustment groove 7, thereby pushing the contact rod 71 to slide towards the connecting groove 76, thereby pushing the gas inside the contraction piston groove 73 into the connecting groove 76 through the inner piston 75. When there is a gap between the sealing rubber ring 64 and the opening of the female end connector, when the inner piston 75 pushes the gas inside the constricting piston groove 73 into the connecting groove 76, the gas cannot be discharged from the ejection groove 8 under the resistance of the extension piston 83 given by the ejection spring 84, and is discharged from the gap between the sealing rubber ring 64 and the opening of the female end connector through the test groove 77. At this time, the ejection rod 81 cannot be pushed out. When the sealing rubber ring 64 is tightly fitted with the opening of the female end connector, the inner piston 75 pushes the gas inside the constricting piston groove 73 into the connecting groove 76. The gas pushes the extension piston 83 to slide away from the connecting groove 76. The push spring 84 is compressed under the push of the extension piston 83, and the push rod 81 is pushed out of the female end connector frame 14 under the push of the extension piston 83. By observing the position of the push rod 81, it is determined whether there is a gap between the sealing rubber ring 64 and the opening of the female end connector. This avoids the problem that the vibration of insertion and removal during high-speed or long-cycle insertion and removal tests may cause gaps in the connection relationship of the fixed end, leading to pressure fluctuations or leakage and misjudgment in subsequent tests, thus improving the accuracy of subsequent tests.
