Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing equipment, specifically to a water testing platform for testing the sealing performance of automotive radiators. Background Technology

[0002] Methods for testing the sealing performance of automotive radiators include wet testing and dry testing. Wet testing uses a water testing bench, where the radiator is manually placed in a water tank. Gas is introduced into the radiator, and the presence of bubbles is observed to determine its sealing performance. However, this method has several drawbacks: First, the radiator is prone to tilting and shaking after being submerged in water, interfering with the observation of bubbles and affecting the accuracy of the test. Second, different radiator models have significant size differences, and existing fixtures are difficult to adapt to various models, requiring frequent fixture changes, which is cumbersome and increases costs. Third, the need for real-time manual adjustment of the radiator's position leads to low testing efficiency and makes it difficult to meet the testing needs of large-scale production. Therefore, there is an urgent need to design a water testing bench for testing the sealing performance of automotive radiators that can solve the above problems. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model aims to provide a water testing platform for testing the sealing performance of automotive radiators, thereby solving the problems of unstable underwater positioning, poor compatibility, and low efficiency inherent in traditional water testing platforms.

[0004] To achieve the above technical objectives, the following technical solutions were adopted:

[0005] A water testing platform for testing the sealing performance of automotive radiators includes a water tank, a support, a water inlet, and a water outlet. The support supports the water tank, which has a water outlet at the bottom and a water inlet at the top. A testing platform is located within the water tank, and the testing platform includes a clamping assembly and a limiting block. The clamping assembly includes a slide rail groove extending transversely through the testing platform, a slider slidably disposed on the slide rail groove, and a clamping plate connected to one side of the slider via a floating joint. An adjusting screw is located within the slide rail groove and is threadedly connected to the slider. Rotating the adjusting screw causes the slider to slide on the slide rail groove, thereby adjusting the position of the clamping plate. The sliders are symmetrically distributed on the left and right sides of the testing platform. The limiting blocks are located on the upper and lower edges of the testing platform, forming a positioning area for placing the radiator together with the clamping assembly.

[0006] Furthermore, the floating joint includes a sleeve threadedly connected to the slider and a connecting rod fixedly connected to the clamping plate. The connecting rod is slidably connected to the sleeve, and a spring is provided on its outer sleeve.

[0007] Furthermore, the slider includes a left slider and a right slider, and the adjusting screw is a two-way lead screw, with its left-hand threaded section cooperating with the right slider and its right-hand threaded section cooperating with the left slider, so as to achieve symmetrical synchronous movement of the slider.

[0008] Furthermore, one end of the adjusting screw is provided with a handle, which makes it easy for the operator to rotate the adjusting screw.

[0009] Furthermore, the limiting block has a right-angled trapezoidal structure, with its right-angled end facing the heat sink, and a buffer pad is provided on the side facing the heat sink.

[0010] Furthermore, the clamping plate has a buffer pad on the side facing the radiator.

[0011] Furthermore, the testing platform is installed inside the water tank via a lifting mechanism, which includes a guide rail fixed to the side wall of the water tank and a cylinder that drives the testing platform to move vertically along the guide rail.

[0012] Furthermore, the water tank is equipped with a heating tube, which can heat the water in the tank and maintain a constant temperature.

[0013] Furthermore, the detection platform is a rectangular steel frame with an internal hollow design to reduce weight and accelerate water flow.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] Compared with existing technologies, this utility model provides a water testing platform for testing the sealing performance of automotive radiators. This utility model features a testing platform within a water tank. Clamping components and limiting blocks on the testing platform together form a positioning area. A bidirectional lead screw, in conjunction with a slider, enables symmetrical and synchronous movement of the clamping plate, firmly clamping automotive radiators of different sizes. No manual intervention is required after clamping, and buffer pads on the clamping plate and limiting blocks prevent damage to the radiator during clamping, ensuring radiator stability during testing. The spring in the floating joint provides cushioning when clamping the radiator, preventing scratches or deformation on the radiator surface due to rigid clamping, thus improving testing reliability and radiator safety. The right-angled trapezoidal limiting block better conforms to the edge of the radiator, improving the limiting effect. The testing platform is driven by a cylinder to move vertically along a guide rail, allowing for convenient immersion or removal of the radiator into or from the water tank, improving testing efficiency. Therefore, this utility model has advantages such as convenient and efficient operation, good versatility, and high testing stability and accuracy. Attached Figure Description

Detailed Implementation

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. The described embodiments are merely some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 As shown, the present invention provides a water testing platform for testing the sealing performance of an automotive radiator, comprising a water tank 1, a support 2, a water inlet 3, and a water outlet 4; the support 2 is used to support the water tank 1, the water tank 1 has a water outlet at the bottom and a water inlet 3 connected to the top, and the support 2 has a testing platform 5, a lifting mechanism 14, and a heating tube 13 inside.

[0023] like Figure 2 As shown, the detection platform 5 is a rectangular steel frame with an internal hollow design to reduce weight and accelerate water flow. A clamping assembly 6 and a limiting block 12 are provided on the detection platform 5. The clamping assembly 6 includes a slide rail groove 7 that runs horizontally through the detection platform 5, a slider 9 slidably disposed on the slide rail groove 7, and a clamping plate 10 connected to one side of the slider 9 via a floating joint 11. An adjusting screw 8 is provided in the slide rail groove 7. The adjusting screw 8 is a two-way lead screw with a handle 81 at one end, threadedly connected to the slider 9. Rotating the adjusting screw 8 causes the slider 9 to slide on the slide rail groove 7, thereby adjusting the position of the clamping plate 10. The sliders 9 are symmetrically distributed on the left and right sides of the detection platform 5, including a left slider 9a and a right slider 9b. The left slider 9a engages with the right threaded section of the adjusting screw 8, and the right slider 9b engages with the left threaded section of the adjusting screw 8. A buffer pad is provided on the side of the clamping plate 10 facing the radiator. Figure 3As shown, the floating joint 11 includes a sleeve 111 threadedly connected to the slider 9 and a connecting rod 112 fixedly connected to the clamping plate 10. The connecting rod 112 is slidably connected to the sleeve 111, and a spring 113 is provided on its outer sleeve. Through the elastic action of the spring 113, a certain buffer can be provided when clamping the radiator to avoid excessive clamping force from damaging the radiator, while ensuring the reliability of clamping. The limiting block 12 is set on the upper and lower edges of the detection platform 5, and together with the clamping assembly 6, forms a positioning area for placing the radiator. It has a right-angled trapezoidal structure, with the right-angle end facing the radiator, and a buffer pad is provided on the side facing the radiator.

[0024] The detection platform 5 is installed in the water tank 1 via a lifting mechanism 14. The lifting mechanism 14 includes a guide rail 141 fixed to the side wall of the water tank 1 and a cylinder 142 that drives the detection platform 5 to move vertically along the guide rail 141.

[0025] The heating tube 13 is located at the bottom of the water tank 1 and can heat the water in the water tank 1 and maintain a constant temperature.

[0026] Its working steps are as follows:

[0027] First, by rotating the handle 81 at one end of the adjusting screw 8, the left and right sliders 9 slide symmetrically and synchronously on the slide rail groove 7 according to the size of the car radiator to be tested. The initial position of the clamping plate 10 is then adjusted. The radiator is placed on the testing platform 5, and the limiting blocks 12 on the upper and lower edges are used for initial positioning, ensuring the radiator is within the positioning area formed by the clamping assembly 6 and the limiting blocks 12. The handle 81 is then rotated further, moving the clamping plate 10 towards the radiator. When the clamping plate 10 contacts the radiator, the spring 113 in the floating joint 11 is compressed, providing a buffering effect until the clamping plate 10 firmly clamps the radiator. The buffer pads on the clamping plate 10 and the limiting blocks 12 are tightly fitted to the radiator, preventing clamping damage.

[0028] Then, the sealing test is performed. The inlet valve 3 is activated to fill water tank 1. Cylinder 142 is activated, driving the testing platform 5 downwards along guide rail 141, smoothly immersing the clamped radiator into the water tank 1. The operator carefully observes the radiator surface for bubbles. If bubbles are present, it indicates a poor seal. The location and number of bubbles are recorded to determine the radiator's sealing performance.

[0029] After the test is completed, start cylinder 142 to move test platform 5 upward so that the radiator can be removed from water tank 1. Turn adjustment handle 81 to loosen clamping plate 10, remove the tested radiator, open drain valve 4 to drain the water in water tank 1, clean water tank 1 and test platform 5 to prepare for the next test.
