Description
Technical Field
[0001] This utility model relates to the technical field of sealing performance testing equipment, and in particular to an automated testing bench for gasket sealing performance. Background Technology
[0002] The automated gasket sealing performance test bench is a key piece of equipment in the field of sealing performance testing equipment. It is widely used in industries with stringent requirements for sealing reliability, such as petrochemicals, water treatment, and power generation. Its core function is to simulate actual industrial working conditions, test the sealing performance of gaskets used in pipelines, containers, valves and other equipment, determine whether there is a risk of leakage, and avoid media leakage, equipment damage or even safety accidents caused by gasket sealing failure. It is an important testing guarantee for ensuring the safe and stable operation of industrial production. Currently, common traditional gasket sealing test equipment typically consists of a fixed base, a manually adjustable clamp, a test ring, a simple pressure test chamber, and a pointer-type pressure gauge. The operator manually places the gasket to be tested on the test ring and moves the clamping block towards the center by rotating the bolt to clamp the gasket, ensuring that the gasket and the test ring fit tightly. Then, a pressure medium is injected into the test chamber through an external pressure source, and the change in the pressure gauge value is observed. If the pressure remains stable, the gasket is considered to be sealed successfully; if the pressure drops, it indicates that there is a leak. This completes the sealing performance test of a single gasket. Existing traditional gasket sealing test equipment has two major shortcomings: First, it relies on manual clamping of the gasket, and the force is difficult to control precisely when manually adjusting the clamping blocks, which can easily lead to uneven force on the gasket and local deformation, thereby compromising the fit and seal between the test chamber and the gasket and causing deviations in the test data. Second, it lacks an effective vibration damping structure, and vibrations are generated during equipment operation. These vibrations are transmitted to the test chamber, causing pressure fluctuations within the chamber, further interfering with the stability of pressure monitoring and exacerbating test data errors. To address these issues, an automated gasket sealing performance testing bench is proposed. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides an automated testing bench for gasket sealing performance, which aims to improve the existing gasket sealing performance testing equipment that relies on manual clamping of gaskets, making it difficult to accurately control the clamping force and causing uneven stress on the gaskets. At the same time, it lacks an effective vibration reduction structure, and the vibration of the equipment during operation can easily interfere with the pressure monitoring of the test chamber and aggravate the error of the test data.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automated testing bench for gasket sealing performance includes a base plate, a plurality of evenly distributed telescopic rods fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the plurality of telescopic rods, a mounting plate fixedly connected to the outer periphery of the plurality of top plates, a vibration damping component provided at the bottom of the mounting plate, a slide rail fixedly connected to the top of the mounting plate, a drive motor mounted at the bottom of the mounting plate, a rotating plate provided at the drive end of the drive motor, two connecting rods slidably connected to the top of the rotating plate, a slider fixedly connected to the top of each of the two connecting rods, and a clamping block fixedly connected to the top of each of the two sliders. As a further description of the above technical solution: The vibration damping assembly includes two connecting plates, both of which are fixedly connected to the bottom of the mounting plate. Two vibration damping columns are fixedly connected to the bottom of each of the two connecting plates, and a support plate is fixedly connected to the bottom of each of the multiple vibration damping columns. As a further description of the above technical solution: Compression springs are fixedly connected to the bottom of both connecting plates, and vibration damping pads are fixedly connected to the bottom of both compression springs. As a further description of the above technical solution: Both of the aforementioned vibration damping pads are fixedly connected to the top of the base plate, and multiple support plates are fixedly connected to the top of the base plate; As a further description of the above technical solution: A telescopic column is fixedly connected to the bottom of the top plate, a test cover is fixedly connected to the bottom of the telescopic column, and an operator is provided on the outside of the test cover; As a further description of the above technical solution: The slide rail has a first slide groove inside, and the top of the rotating plate has two second slide grooves. As a further description of the above technical solution: Both sliders are slidably connected inside the slide rail; As a further description of the above technical solution: A test ring is fixedly connected to the top of the mounting plate.
[0005] This utility model has the following beneficial effects: 1. In this utility model, through the cooperation between the drive motor, rotating plate, connecting rod, slider, slide rail, and clamping block, the drive motor drives the rotating plate to rotate when it is working. The rotating plate generates a lateral thrust on the connecting rod through the two slide grooves at the top, causing the connecting rod to drive the slider to slide stably along the slide groove one in the slide rail. This, in turn, causes the two clamping blocks to move towards each other and evenly abut against the pad on the test ring, realizing the automated and precise clamping of the pad. This improves the problems of relying on manual clamping, low testing accuracy, and poor efficiency in the prior art.
[0006] 2. In this utility model, through the cooperation between the connecting plate, the damping column, the compression spring, the damping pad, the support plate, and the mounting plate, the vibration generated by the operation of the equipment is transmitted to the mounting plate, and then the connecting plate transmits the vibration to the damping column and the compression spring. The damping column initially buffers the impact force through rigid deformation, and the compression spring converts the vibration kinetic energy into elastic potential energy and slowly releases it to weaken the vibration. This improves the problems of lacking an effective vibration damping structure and large error in test data in the prior art. Attached Figure Description

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Reference Figures 1-3This utility model provides an embodiment of an automated gasket sealing performance testing bench, comprising a base plate 1 made of carbon structural steel with a rust-proof paint coating; the base plate 1 serves as the foundation and fixed carrier of the testing bench, bearing the weight of all components, ensuring overall structural stability, and preventing displacement during testing. Multiple evenly distributed telescopic rods 2 are fixedly connected to the top of the base plate 1, and a top plate 3 is fixedly connected to the top of the telescopic rods 2. Mounting plates 4 are fixedly connected to the outer periphery of the top plates 3. Mounting plates 4 are the core testing platform, providing a flat reference surface for gasket clamping and testing. Vibration damping components are provided at the bottom of the mounting plates 4, and a slide rail is fixedly connected to the top of the mounting plates 4. 8. A drive motor 6 is installed at the bottom of the mounting plate 4. The drive motor 6 replaces manual operation and avoids uneven clamping force. A rotating plate 7 is set at the drive end of the drive motor 6. Its function is to convert the rotational power of the motor into the lateral thrust of the connecting rod 9. The connecting rod 9 is guided to slide towards each other through the slide groove 21, so that the clamping block 11 moves synchronously. Two connecting rods 9 are slidably connected to the top of the rotating plate 7. A slider 10 is fixedly connected to the top of each of the two connecting rods 9. A clamping block 11 is fixedly connected to the top of each of the two sliders 10. The clamping block 11 directly clamps the pad. The uniform force is achieved through automatic drive, avoiding pad deformation caused by manual clamping and improving test accuracy.
[0011] Reference Figure 4 and Figure 5 The vibration damping component includes two connecting plates 16. The surface of the connecting plates 16 is treated with rust prevention. Both connecting plates 16 are fixedly connected to the bottom of the mounting plate 4. Two vibration damping columns 15 are fixedly connected to the bottom of each of the two connecting plates 16. Support plates 12 are fixedly connected to the bottom of each of the multiple vibration damping columns 15. The support plates 12 provide rigid support to ensure that the vibration damping columns 15 always remain vertical, thus ensuring the long-term stable operation of the vibration damping component.
[0012] Reference Figures 1-5Compression springs 14 are fixedly connected to the bottom of both connecting plates 16. When the mounting plate 4 transmits vibration, the compression springs 14 convert the vibration kinetic energy into elastic potential energy through axial expansion and contraction, further weakening the residual vibration not absorbed by the damping column 15, preventing minor vibrations from being transmitted to the test chamber, and ensuring stable pressure inside the chamber. Damping pads 13, made of nitrile rubber, are fixedly connected to the bottom of the two compression springs 14. Both damping pads 13 are fixedly connected to the top of the base plate 1. Multiple support plates 12 are fixedly connected to the top of the base plate 1. A telescopic column 17 is fixedly connected to the bottom of the top plate 3. During testing, the column extends to push the test cover 18 down, engaging with the test ring 5. A closed test chamber is formed; after the test, the test cover 18 is shortened and raised to facilitate the removal and placement of the gasket. The test cover 18 is fixedly connected to the bottom of the telescopic column 17. The surface of the test cover 18 is polished and cooperates with the test ring 5 to form a closed test chamber to contain the pressure test medium and provide a stable working environment for the gasket sealing performance test. An operator 19 is set on the outside of the test cover 18. The operator 19 replaces the traditional manual monitoring and improves the test efficiency and data accuracy. The slide rail 8 has a slide groove 20 inside, and the top of the rotating plate 7 has two slide grooves 21. The two sliders 10 are slidably connected inside the slide rail 8. The test ring 5 is fixedly connected to the top of the mounting plate 4.
[0013] Working principle: First, the test pad is placed on the test ring 5 on the top of the mounting plate 4, and the drive motor 6 at the bottom of the mounting plate 4 is started. The drive motor 6 drives the rotating plate 7 to rotate. Since there are two sliding grooves 21 on the top of the rotating plate 7, and the bottom of the two connecting rods 9 are slidably connected in the sliding grooves 21, the rotating plate 7 will generate a lateral thrust on the connecting rods 9 through the sliding grooves 21 when it rotates, causing the two connecting rods 9 to slide towards each other along the sliding grooves 21. At the same time, the slider 10 fixed on the top of the connecting rod 9 is slidably connected in the sliding groove 20 inside the slide rail 8. The sliding groove 20 provides a stable guide for the slider 10 and prevents the connecting rods 9 from deviating. Finally, the two sliders 10 drive the clamping block 11 on the top to move synchronously until the clamping block 11 tightly and evenly abuts against both sides of the pad, completing the automatic clamping and fixing of the pad. There is no need for manual adjustment of the bolts, which not only ensures consistent clamping force and avoids pad deformation, but also greatly improves the efficiency of batch testing.
[0014] Subsequently, when the equipment vibrates during operation, the vibration is first transmitted to the mounting plate 4. The two connecting plates 16 fixed at the bottom of the mounting plate 4 transmit the vibration to the damping column 15 and the compression spring 14 below. The damping column 15 initially buffers the vibration impact force through its own rigid deformation. At the same time, the compression spring 14 contracts under the force of vibration, converting the vibration kinetic energy into elastic potential energy, and then further weakens the vibration by slowly releasing the elastic potential energy. Finally, the remaining minor vibration is transmitted to the damping pad 13 on the top of the base plate 1 through the support plate 12. The damping pad 13 absorbs the residual vibration through its own flexible material, effectively blocking the transmission of vibration to the test ring 5 and the subsequently closed test cover 18, ensuring the stability of the pressure in the test chamber and avoiding pressure fluctuations caused by vibration from interfering with the monitoring data.
[0015] Finally, during the sealing performance test, the telescopic column 17 at the bottom of the top plate 3 extends, causing the test cover 18 at the bottom to descend, so that the test cover 18 is tightly fastened to the outer circumference of the test ring 5, forming a closed test chamber. The operator controls the external pressure source to inject pressure medium into the test chamber through the operator 19. The operator can monitor the pressure change in the chamber in real time through the operator 19 to judge the gasket sealing performance. After the test, the telescopic column 17 shortens, causing the test cover 18 to rise, driving the motor 6 to rotate in the opposite direction. Through the rotating plate 7 and the connecting rod 9, the clamp 11 moves in the opposite direction to loosen the gasket, and the gasket that has completed the test can be taken out to enter the next round of testing.
[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
