Description

Technical Field

[0001] This utility model relates to the field of sealing ring testing technology, and in particular to a device for testing extrusion-resistant sealing rings. Background Technology

[0002] A sealing ring is an elastomeric component used to prevent fluid leakage and is widely used in various machines and equipment. Its performance directly affects the sealing effect and operational stability of the equipment. Therefore, rigorous testing of sealing rings to ensure that key indicators such as dimensions, hardness, mechanical properties, temperature resistance, and corrosion resistance meet requirements is crucial for ensuring the safe operation of equipment. Sealing ring testing is a key step in ensuring that sealing rings possess good sealing performance and durability during use.

[0003] An existing pressure-resistant sealing ring testing device is not convenient for measuring the width of the product according to actual needs to stably limit and fix it when performing pressure testing on the product. When the product is not fixed stably, it will cause errors in the data of the product pressure test. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a test device for compression-resistant sealing rings.

[0005] This utility model is achieved using the following technical solution: a test device for a compression-resistant sealing ring, comprising a fixed plate, a support rod fixedly connected to the top of the fixed plate, an installation frame fixedly connected to the top of the support rod, a positioning screw connected internally to the installation frame, a bearing frame connected to the surface of the positioning screw, a cylinder fixedly connected to the top of the bearing frame, a test mold fixedly connected to the bottom of the cylinder, and a support rod fixedly connected to the bottom of the cylinder;

[0006] A fixing sleeve is fixedly connected to the top of the fixing plate, a spring is fixedly connected to the top of the fixing plate, a buffer column is fixedly connected to the top of the spring, a processing plate is fixedly connected to the top of the buffer column, an adjustment groove is provided on the top of the processing plate, a first limiting clamp is slidably connected inside the adjustment groove, a connecting plate is fixedly connected to the left end of the first limiting clamp, a second limiting clamp is threadedly connected inside the bearing frame, and a second limiting clamp is slidably connected inside the adjustment groove.

[0007] As a further improvement to the above solution, the number of support rods is set to two, and the two support rods are symmetrically distributed on the left and right sides with the support pole as the center, and the support rods are snapped onto the front of the support pole.

[0008] With the above technical solution, the two support rods are symmetrically distributed on the left and right sides with the support rod as the center and are snapped into the front of the support rod. This helps to maintain the stability of the test mold during the extension and retraction of the cylinder. When the cylinder applies pressure downward, the cooperation between the support rod and the support rod can prevent the test mold from shifting, ensuring that the pressure can be applied vertically and evenly to the sealing ring, thereby improving the accuracy of the test results.

[0009] As a further improvement to the above solution, the number of the fixing sleeves and springs is set to four, and the four fixing sleeves and springs are symmetrically distributed around the fixing plate.

[0010] As a further improvement to the above solution, the spring is slidably connected inside the fixed sleeve, and the buffer column is slidably connected inside the fixed sleeve.

[0011] As a further improvement to the above scheme, the number of the adjustment slots is set to two, and the two adjustment slots are symmetrically distributed front and back with the processing plate as the center.

[0012] As a further improvement to the above solution, the first limiting fixture is slidably connected inside the fixed plate, and the second limiting fixture is slidably connected inside the processing plate.

[0013] Through the above technical solution, the presence of the connecting plate enhances the stability of the second limiting clamp structure. At the same time, when adjusting the position of the second limiting clamp, the operation can be carried out through the connecting plate, which is more convenient and faster, and also helps to improve the reliability of the entire fixing structure.

[0014] As a further improvement to the above solution, the left end of the second limiting fixture is inserted into the first limiting fixture, and the right end of the second limiting fixture is fixedly connected to a connecting plate. The connecting plate and the second limiting fixture are symmetrically distributed with the processing plate as the center.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows operators to slide and adjust the left and right positions of limit clamps one and two within the processing plate and adjustment groove when the adjustable screw is rotated to remove them from the inside of the connecting plate. This enables convenient and stable clamping of products that require pressure testing, ensuring the accuracy of the equipment during product testing. When the processing plate is subjected to downward pressure, the buffer column drives the spring inside the fixed sleeve to buffer the downward pressure, preventing the downward pressure from being directly borne by the processing plate and increasing the service life of the equipment.

[0017] This invention features four fixed sleeves and springs symmetrically distributed around a fixed plate. The springs are slidably connected inside the fixed sleeves, and the buffer column is slidably connected inside the fixed sleeves with its top connected to the processing plate. During testing, when the test mold applies pressure to the sealing ring, an impact force may be generated. The structure of the springs and fixed sleeves can buffer the impact force, absorbing some of the impact force and protecting the various components of the device from damage due to excessive impact. It can also reduce the impact force on the test results, making the testing process more stable. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0026] Please combine Figure 1-5 The compression-resistant sealing ring testing device of this embodiment includes a fixed plate 1, a support rod 2 fixedly connected to the top of the fixed plate 1, an installation frame 3 fixedly connected to the top of the support rod 2, a positioning screw 4 internally threaded to the installation frame 3, a bearing frame 5 threaded to the surface of the positioning screw 4, a cylinder 6 fixedly connected to the top of the bearing frame 5, a test mold 7 fixedly connected to the bottom of the cylinder 6, and a support rod 8 fixedly connected to the bottom of the cylinder 6.

[0027] A fixing sleeve 9 is fixedly connected to the top of the fixing plate 1. A spring 10 is fixedly connected to the top of the fixing plate 1. A buffer column 11 is fixedly connected to the top of the spring 10. A processing plate 12 is fixedly connected to the top of the buffer column 11. An adjustment groove 13 is provided on the top of the processing plate 12. A limit clamp 14 is slidably connected inside the adjustment groove 13. A connecting plate 15 is fixedly connected to the left end of the limit clamp 14. A second limit clamp 16 is threadedly connected inside the bearing frame 5. The second limit clamp 16 is slidably connected inside the adjustment groove 13. By rotating the adjustment screw 17, the connection... When the inside of the connecting plate 15 is removed, the operator can slide and adjust the left and right positions of the first limiting clamp 14 and the second limiting clamp 16 inside the processing plate 12 and the adjusting groove 13. This allows for convenient limiting and stable clamping of the product to be pressure tested according to actual needs, ensuring the accuracy of the equipment when testing the product. When the processing plate 12 is subjected to downward pressure, the buffer column 11 drives the spring 10 to buffer the downward pressure inside the fixed sleeve 9, avoiding the downward pressure being directly borne by the processing plate 12 and increasing the service life of the equipment.

[0028] The number of support rods 8 is set to two, and the two support rods 8 are symmetrically distributed on the left and right sides with the support pole 2 as the center. The support rods 8 are snapped into the front of the support pole 2.

[0029] Two support rods 8 are symmetrically distributed around the support rod 2 and are engaged with the front of the support rod 2. This helps to maintain the stability of the test mold 7 during the extension and retraction of the cylinder 6. When the cylinder 6 applies downward pressure, the cooperation between the support rods 8 and the support rod 2 can prevent the test mold 7 from shifting, ensuring that the pressure can be applied vertically and evenly to the sealing ring, thereby improving the accuracy of the test results.

[0030] The number of fixed sleeves 9 and springs 10 is set to four, and the four fixed sleeves 9 and springs 10 are symmetrically distributed with the fixed plate 1 as the center.

[0031] Spring 10 is slidably connected inside the fixed sleeve 9, and buffer column 11 is slidably connected inside the fixed sleeve 9. By setting four fixed sleeves 9 and springs 10 symmetrically distributed around the fixed plate 1, with springs 10 slidably connected inside the fixed sleeve 9 and buffer column 11 slidably connected inside the fixed sleeve 9 and connected to the processing plate 12 at the top, during the test, when the test mold 7 applies pressure to the sealing ring, an impact force may be generated. The structure of spring 10 and fixed sleeve 9 can play a buffering role, absorbing part of the impact force, protecting the various components of the device from damage due to excessive impact, and also reducing the possible impact force on the test results, making the test process more stable.

[0032] The number of adjustment slots 13 is set to two, and the two adjustment slots 13 are symmetrically distributed front and back with the processing plate 12 as the center.

[0033] Limiting fixture 14 is slidably connected inside the fixed plate 1, and limiting fixture 2 16 is slidably connected inside the processing plate 12.

[0034] The presence of the connecting plate 15 enhances the stability of the limiting clamp 16 structure. At the same time, when adjusting the position of the limiting clamp 16, it can be operated through the connecting plate 15, which is more convenient and faster, and also helps to improve the reliability of the entire fixing structure.

[0035] The left end of the second limiting fixture 16 is connected to the first limiting fixture 14, and the right end of the second limiting fixture 16 is fixedly connected to the connecting plate 15. The connecting plate 15 and the second limiting fixture 16 are symmetrically distributed with the processing plate 12 as the center.

[0036] The implementation principle of the compression-resistant sealing ring testing device in this embodiment is as follows: When the adjusting screw 17 is rotated and removed from the inside of the connecting plate 15, the operator can slide and adjust the left and right positions of the limiting clamp 14 and the limiting clamp 2 16 inside the processing plate 12 and the adjusting groove 13. This allows for convenient limiting and stable clamping according to the actual product requiring pressure testing, ensuring the accuracy of the equipment during product testing. When the processing plate 12 is subjected to downward pressure, the buffer column 11 drives the spring 10 to buffer the downward pressure inside the fixed sleeve 9, preventing the downward pressure from being directly applied to the processing plate. The 12-type structure increases the service life of the equipment. By setting four fixed sleeves 9 and springs 10 symmetrically distributed around the fixed plate 1, the springs 10 are slidably connected inside the fixed sleeves 9, and the buffer column 11 is slidably connected inside the fixed sleeves 9 and connected to the processing plate 12 at the top. During the test, when the test mold 7 applies pressure to the sealing ring, an impact force may be generated. The structure of the springs 10 and fixed sleeves 9 can play a buffering role, absorbing part of the impact force, protecting the various parts of the device from damage due to excessive impact, and reducing the possible impact force on the test results, making the test process more stable.
