Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, specifically relating to a testing tooling for the pressure resistance performance of sealing rings. Background Technology

[0002] Sealing rings are original components or parts used to prevent leakage of liquids or solid particles from adjacent fusion surfaces and to prevent external residues such as dust and water from entering mechanical equipment parts. Sealing rings should have good sealing performance within a certain operating pressure and temperature range, and should automatically improve their sealing performance as pressure increases. During use, to ensure the sealing performance of the sealing rings under certain pressures, pressure resistance tests are performed. According to CN202320050598.X, a pressure resistance testing fixture for a sealing ring includes a support base, a support plate, a cylinder, and a pressure gauge. The support plate is fixed to the bottom of the support base, and a cylinder is located at the center of the top of the support plate. A pressure gauge is located on the outer side of the support plate. A connecting rod is fixed to the output end of the cylinder, and a connecting sleeve is fixed to the end of the connecting rod away from the cylinder. The detachable design of the inner support block and the upper pressure plate facilitates the selection and fixing of the corresponding test platform and upper pressure plate according to the diameter of the sealing ring. The use of scale lines, a pressure sensor, and a pressure gauge allows for easy observation of the deformation of the sealing ring under different pressures, improving the practicality of the testing fixture. The heating chamber, heating ring rod, and heat-conducting rod work together to heat the upper part of the test platform, accelerating the heating speed of the sealing ring after it is placed on the top of the test platform, thus enabling the testing of the pressure resistance performance of the sealing ring at different temperatures.

[0003] The aforementioned sealing ring pressure resistance testing fixture also has certain drawbacks. Typically, one set of fixtures can only test one type of sealing ring. When testing different types of sealing rings, it is necessary to disassemble the inner support block and upper pressure plate and replace them with inner support blocks and upper pressure plates that match the sealing rings. This operation is time-consuming and labor-intensive, reducing testing efficiency. Repeated disassembly can also affect the service life of the equipment. Furthermore, it is not convenient to quickly remove the tested sealing rings, requiring manual removal, which brings inconvenience to the collection work. Therefore, we propose a sealing ring pressure resistance performance testing fixture. Utility Model Content

[0004] The purpose of this invention is to provide a testing fixture for the pressure resistance performance of sealing rings, in order to solve the problems mentioned in the background art. Typically, one set of fixtures can only test one type of sealing ring. When testing different types of sealing rings, it is necessary to disassemble the inner support block and the upper pressure plate and replace them with inner support blocks and upper pressure plates that match the sealing rings. This operation is time-consuming and labor-intensive, reduces testing efficiency, and multiple disassemblies will affect the service life of the equipment. Moreover, it is not convenient to quickly remove the tested sealing rings, which requires manual removal by personnel and brings inconvenience to the collection work.

A cylinder 3 is fixedly connected to the top of the workbench 1, and the upper pressure plate 2 is fixedly connected to the bottom of the cylinder 3. Multiple annular plates 4 of different specifications are provided on the outer side of the upper pressure plate 2. The annular plates 4 are fixedly connected to each other and to the upper pressure plate 2. A pressure sensor is embedded in the bottom of the upper pressure plate 2 and each annular plate 4. A groove 5 is provided at the bottom of the workbench 1, and multiple annular grooves 6 of different specifications are provided on the outer side of the groove 5. Graduation lines are provided inside the groove 5 and the annular plates 4 and annular grooves 6 respectively. A mold 7 is movably connected inside the annular groove 6, and a telescopic device is provided at the bottom of the mold 7. A push plate 8 is movably connected inside the workbench 1. A pressure gauge 9 is fixedly connected to the right side, and a collection area 10 is fixedly connected to the front of the workbench 1. A collection box 11 is placed inside the collection area 10. Different types of sealing rings can be placed into the molds 7 on the grooves 5 or different annular grooves 6. The cylinder 3 is started by the control terminal, which drives the upper pressure plate 2 to move down and the set annular plate 4 to move down. The upper pressure plate 2 or the annular plate 4 compresses the sealing ring for testing. The pressure value is recorded by the set pressure sensor and displayed on the pressure gauge 9. The scale line is used to compare the sealing ring before and after the test, which makes it easy to check the condition of the sealing ring after the test. After the test is completed, the telescopic device is started to drive the mold 7 to move up. Due to gravity, the mold 7 is retracted as a whole, similar to folding a water cup away. At this time, the set sealing ring is exposed, and the set push plate 8 pushes the sealing ring into the collection box 11 for subsequent collection.

[0017] Specifically, the telescopic device is a first electric push rod 12. The front of the worktable 1 has a receiving cavity 13. The bottom of the first electric push rod 12 is fixedly connected to the inside of the receiving cavity 13, and the top is fixedly connected to the bottom of the mold 7.

[0019] Specifically, a heating wire 16 and a temperature sensor 17 are fixedly connected inside both the groove 5 and the annular groove 6. A display 18 is fixedly connected to the right side of the pressure gauge 9. A controller 19 is fixedly connected to one end of the display 18. The temperature sensor 17 is electrically connected to the display 18. The controller 19 controls the heating temperature of the heating wire 16 and displays it on the display 18, which is convenient for testing the pressure resistance of the sealing ring at different temperatures.

[0021] Specifically, a slide 23 is fixedly connected to the top of the collection box 11. The top of the slide 23 is flush with the top of the mold 7. The slide 23 facilitates the sealing ring to slide down quickly and enter the collection box 11.

[0022] In this implementation scheme, when using the testing fixture, different types of sealing rings can be placed inside the mold 7 on the groove 5 or different annular grooves 6. The cylinder 3 is started by the control terminal, which drives the upper pressure plate 2 to move down and the set annular plate 4 to move down. The upper pressure plate 2 or the annular plate 4 compresses the sealing ring for testing. The pressure value is recorded by the set pressure sensor and displayed on the pressure gauge 9. The scale line is used to compare the sealing ring before and after the test, which makes it easy to check the condition of the sealing ring after the test. After the test is completed, the telescopic device is started to drive the mold 7 to move up. Due to gravity, the mold 7 is retracted as a whole, similar to folding a water cup away. At this time, the set sealing ring is exposed, and the set push plate 8 pushes the sealing ring into the collection box 11 for subsequent collection.
