Description

Technical Field

[0001] This utility model relates to the field of sealing testing device technology, and in particular to a testing device for mechanical seal components. Background Technology

[0002] Seals are materials or parts that prevent fluid or solid particles from leaking between adjacent mating surfaces and prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. The sealing performance test adopts the air pressure value sealing test principle and is mainly used for sealing test of automobiles, trains, airplanes and ships.

[0003] By applying stable and adjustable pressure to the sample through a pressure control system, the actual working conditions are simulated, and various data during the test process, such as pressure changes and leakage, are recorded and analyzed to evaluate the performance of the mechanical seal. Before the test, the product needs to be manually fed into the testing device. Manual feeding is usually slower than automated equipment and requires more time for preparation and confirmation, which may lead to a decrease in testing efficiency, especially for large-scale production or testing scenarios that require rapid response. Therefore, this utility model proposes a mechanical seal component testing device to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a mechanical seal component testing device to solve the problem that manual feeding in the prior art is usually slower than automated equipment and requires more time for preparation and verification, which may lead to a decrease in testing efficiency.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a mechanical seal component testing device, including a workbench, a support frame and a sealing plate. The support frame is fixedly connected to the right side of the workbench.

The top of the slide rail is slidably connected to the slider, the top of the slider is hinged to the connecting rod via the second hinge rod, and the left end of the connecting rod is hinged to the rotating rod.

[0007] A further improvement is that the extrusion mechanism includes a cylinder and a pressure block. The cylinder is fixedly installed on the top of the support frame, and the pressure block is fixedly connected to the output end of the cylinder. The top of the pressure block is hinged to one end of the rotating rod through a first hinge rod.

[0008] A further improvement is that a limiting frame is provided on one side of the sealing disk, the guide rod is parallel to the limiting frame, and the outer wall of the sealing disk is fitted and connected to the inner wall of the limiting frame.

[0009] A further improvement is that the pressure transmission mechanism includes an air pump, an air transmission pipe, and a pressure gauge. An air pump is fixedly installed on the right side of the workbench. The output end of the air pump is connected to the bottom of the sealing plate through the air transmission pipe. A pressure gauge is installed on the outside of the air transmission pipe.

[0010] A further improvement is that multiple sealing discs are stacked on the inner side of the guide rod, one end of the slider is parallel to the sealing disc at the bottom of the guide rod, and the outer wall of the sealing disc is in contact with the inner side of the guide rod.

[0012] The beneficial effects of this utility model are as follows: the cylinder drives the pressure block to move downwards while simultaneously driving the rotating rod to swing via the first hinge rod. The rotating rod is hinged to the slider via the connecting rod and the second hinge rod, and the slide rail restricts the movement trajectory of the slider, causing the slider to move out of the bottom end of the guide rod, so that the sealing cover at the bottommost end of the inner side of the guide rod falls onto the slide rail. When the cylinder drives the pressure block to move upwards to reset, the pressure block drives the slider to reset via the rotating rod and the connecting rod. The slider squeezes the sealing cover at the lowest end of the guide rod and moves it towards the sealing plate. The limiting frame limits the sealing cover to move it exactly above the sealing plate, completing the automatic feeding of the sealing cover and improving the detection efficiency.

[0018] To enhance understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a mechanical seal component testing device, including a workbench 1, a support frame 2, and a sealing disc 4. The support frame 2 is fixedly connected to the right side of the workbench 1. A pressing mechanism is provided at the top of the support frame 2, and a sealing disc 4 is provided at the bottom of the support frame 2. A slide rail 6 is fixedly installed on the left side of the workbench 1. A guide rod 5 is provided at the right end of the slide rail 6. An automatic feeding mechanism is provided on the slide rail 6. A pressure conveying mechanism is provided on the right side of the workbench 1. Multiple sealing caps are stacked inside the guide rod 5. The automatic feeding mechanism drives the sealing cap at the bottom of the guide rod 5 to automatically move to the top of the sealing disc 4. The pressing mechanism presses the sealing cap and the sealing disc 4 together. The pressure conveying mechanism pressurizes the interior of the sealing disc 4 to a certain value, and observes the change in pressure value after a period of time to judge the sealing performance. If the pressure value remains stable or drops within the allowable range, the sealing performance is considered good; otherwise, there may be a leakage problem.

[0020] Multiple sealing discs are stacked on the inner side of the guide rod 5. One end of the slider 7 is parallel to the sealing disc at the bottom of the guide rod 5, and the outer wall of the sealing disc is in contact with the inner side of the guide rod 5.

[0021] The extrusion mechanism includes a cylinder 8 and a pressure block 9. The cylinder 8 is fixedly installed on the top of the support frame 2. The pressure block 9 is fixedly connected to the output end of the cylinder 8. The top of the pressure block 9 is hinged to one end of the rotating rod 11 through a first hinge rod 10. The pressure block 9 includes a rectangular plate and a bracket. The rectangular plate is fixedly connected to the output end of the cylinder 8. The bracket is symmetrically fixedly connected to the bottom of the rectangular plate, and the bracket is designed as an L-shaped structure.

[0022] A limiting frame 3 is provided on one side of the sealing disk 4, the guide rod 5 is parallel to the limiting frame 3, and the outer wall of the sealing disk 4 is fitted and connected to the inner wall of the limiting frame 3.

[0023] The output end of cylinder 8 can drive the pressure block 9 to move downward. The pressure block 9 can press the bottom of the sealing cover and the sealing plate 4 tightly, so that the sealing cover and the sealing plate 4 are completely in contact. The pressure applied by cylinder 8 is constant, which is used to test the sealing performance of the sealing cover under fixed pressure. After the test is completed, cylinder 8 drives the pressure block 9 to move upward and separate from the sealing cover, and remove the sealing cover from the top of the sealing plate 4.

[0024] The automatic feeding mechanism includes a slider 7, a rotating rod 11, a second hinge rod 12, and a connecting rod 13. The top of the slide rail 6 is slidably connected to the slider 7. The top of the slider 7 is hinged to the connecting rod 13 via the second hinge rod 12. The left end of the connecting rod 13 is hinged to the rotating rod 11. The cylinder 8 drives the pressure block 9 to move downwards and simultaneously drives the rotating rod 11 to swing via the first hinge rod 10. The rotating rod 11 is hinged to the slider 7 via the connecting rod 13 and the second hinge rod 12. The slide rail 6 restricts the movement trajectory of the slider 7, causing the slider 7 to move out of the bottom end of the guide rod 5, so that the sealing cover at the bottom inner side of the guide rod 5 falls onto the slide rail 6. When the cylinder 8 drives the pressure block 9 to move upwards and reset, the pressure block 9 drives the slider 7 to reset via the rotating rod 11 and the connecting rod 13. The slider 7 presses the sealing cover at the lowest end of the guide rod 5 towards the sealing plate 4, and the limiting frame 3 moves the sealing cover exactly above the sealing plate 4, completing the automatic feeding of the sealing cover.

[0025] The pressure supply mechanism includes an air pump 14, an air supply pipe 15, and a pressure gauge 16. The air pump 14 is fixedly installed on the right side of the workbench 1. The output end of the air pump 14 is connected to the bottom of the sealing plate 4 through the air supply pipe 15. The pressure gauge 16 is installed on the outside of the air supply pipe 15. After the sealing cover is attached to the top of the sealing plate 4, the air pump 14 and the air supply pipe 15 cooperate to pressurize the inside of the sealing plate 4. The sealing performance is judged by observing the pressure gauge 16 fixed at a certain value and observing the change of the pressure value of the pressure gauge 16 after a period of time. If the pressure value remains stable or drops within the allowable range, the sealing performance is considered to be good; otherwise, there may be a leakage problem.

[0026] In this mechanical seal component testing device, cylinder 8 drives pressure block 9 downward while simultaneously driving rotating rod 11 to swing via hinge rod 10. Rotating rod 11 is hinged to slider 7 via connecting rod 13 and hinge rod 12, and slide rail 6 restricts the movement trajectory of slider 7, causing slider 7 to move out of the bottom of guide rod 5, so that the sealing cover at the bottom inner side of guide rod 5 falls onto slide rail 6. When cylinder 8 drives pressure block 9 to move upward and reset, pressure block 9 drives slider 7 to reset via rotating rod 11 and connecting rod 13. Slider 7 presses the sealing cover at the lowest end of guide rod 5 towards sealing disc 4, and the limiting frame 3 moves the sealing cover exactly above sealing disc 4, completing the automatic feeding of sealing cover and improving testing efficiency.
