Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring testing, and in particular to a rubber sealing ring deformation resistance testing device. Background Technology

[0002] Rubber sealing rings are rubber products used for sealing. They can provide a sealing function in a static or dynamic state under specified temperature, pressure and different liquid and gas media. They play a key role in many mechanical equipment, are commonly used for static sealing and reciprocating motion sealing, are applicable to a variety of gas and liquid media, and have diverse working environments.

[0003] Most existing rubber seal testing devices have a fixed platform installation structure. The rubber seal is placed and positioned on the fixed platform, and tensile and compressive deformation is tested through tensile and compressive structures. However, there are many obstructions on the outer side and the bottom when observing and measuring deformation, which reduces the observation effect of tensile deformation from all directions and the convenience of force measurement. This leads to a decrease in the effectiveness and ease of use of the rubber seal testing device.

[0004] Therefore, to address the problem that existing rubber seal testing devices suffer from significant obstruction on the outer side and lower end during observation and deformation force measurement, resulting in reduced omnidirectional tensile deformation observation and force measurement convenience, thus diminishing the effectiveness and ease of use of the rubber seal testing device, a rubber seal deformation resistance testing device can be designed. Utility Model Content

[0005] In order to overcome the problem that existing rubber seal testing devices have too much obstruction on the outer side and bottom when observing and measuring deformation force, which reduces the effect of observing tensile deformation from all directions and the convenience of force measurement, thus reducing the effectiveness and convenience of the rubber seal testing device.

[0006] The technical solution of this utility model is as follows: a rubber sealing ring anti-deformation testing device, including a base body; it also includes a limiting frame and a lifting platform. A support platform is fixedly connected to the front end of the base body, and a limiting frame is installed on the upper end of the support platform. A power motor is installed on the inner side of the support platform. A threaded rod is installed on the rotating shaft of the power motor through a coupling. The outer side of the threaded rod is threadedly connected to the lifting platform. The lifting platform is slidably connected to the support platform. A rotating frame is rotatably connected to the outer side of the lifting platform through a rotating shaft. A limiting block for stretching the rubber sealing ring is rotatably connected to the outer side of the rotating frame through a rotating shaft. A stretching platform for positioning the rubber sealing ring is rotatably connected to the upper end of the limiting block through a rotating shaft. The stretching platform and the limiting block are slidably connected to the limiting frame.

[0007] Preferably, a limiting frame is installed on the base body and support platform, and a power motor drives the threaded rod to rotate, thereby cooperating with the support platform to drive the lifting platform to rise and fall, so as to drive the rotating frame and the limiting block to move. In conjunction with the limiting frame, the limiting block and the stretching platform move in the horizontal plane, and then the rubber sealing ring is placed and stretched by the inward and outward contraction of the four stretching platforms.

[0008] Preferably, a sliding groove is provided at the lower end of the base body, and a support frame is fixedly connected to the rear end of the base body, with a first hydraulic push rod installed at the rear end of the support frame.

[0009] Preferably, a movable frame is fixedly connected to the output end of the first hydraulic push rod, and a support rod is fixedly connected to the rear end of the movable frame. The movable frame and the base body are slidably connected through a slide groove and the support rod.

[0010] Preferably, the front end of the movable frame is equipped with an installation platform, the upper end of the support frame is equipped with a fixed frame, the front end of the fixed frame is equipped with a second hydraulic push rod, and a limit plate is fixedly connected to the output end of the second hydraulic push rod.

[0011] Preferably, a mounting bracket is slidably connected to the outer side of the limiting plate, a lower pressing platform is installed at the lower end of the mounting bracket, and a fixing platform is installed at the upper end of the mounting platform.

[0012] Preferably, a mounting plate is installed on the upper end of the fixed platform, a material platform is provided on the upper end of the mounting plate, and a connecting rod is fixedly connected to the lower end of the material platform. The connecting rod is slidably connected to the fixed platform and the mounting plate.

[0013] Preferably, a support spring is installed between the mounting plate and the material platform. A rotating table is rotatably connected to the inner side of the mounting plate via a rotating joint. A scraper body is installed on the outer side of the rotating table. The rotating table and the scraper body are rotatably connected to the material platform.

[0014] The beneficial effects of this utility model are:

[0015] This rubber sealing ring deformation resistance testing device uses a base platform and a support platform to install a limiting frame. A power motor drives a threaded rod to rotate, which in turn drives a lifting platform to rise and fall. The limiting frame, in conjunction with the rotating frame, allows the limiting block and the stretching platform to move horizontally. Four stretching platforms support the inner edge of the rubber sealing ring, thereby increasing the openness of the device during tensile deformation observation, facilitating all-round observation by the tester. It also makes it easy to attach strain gauges to the rubber sealing ring, improving the convenience of use and the effectiveness of observation and testing. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a rubber sealing ring deformation resistance testing device, including a base body 1; it also includes a limit frame 21 and a lifting platform 24. A support platform 20 is fixedly connected to the front end of the base body 1, and the limit frame 21 is installed on the upper end of the support platform 20. A power motor 22 is installed on the inner side of the support platform 20. A threaded rod 23 is installed on the shaft of the power motor 22 through a coupling. The lifting platform 24 is threadedly connected to the outer side of the threaded rod 23. The lifting platform 24 is slidably connected to the support platform 20. A rotating frame 25 is rotatably connected to the outer side of the lifting platform 24 through a rotating shaft. The outer side of the rotating frame 25 is rotatably connected to the outer side of the rotating frame 25 through a rotating shaft. A limiting block 26 for stretching the rubber sealing ring is provided. The upper end of the limiting block 26 is rotatably connected to a stretching table 27 for positioning the rubber sealing ring via a rotating shaft. The stretching table 27 and the limiting block 26 are slidably connected to the limiting frame 21. The limiting frame 21 is installed through the base body 1 and the support platform 20. The power motor 22 drives the threaded rod 23 to rotate, thereby cooperating with the support platform 20 to drive the lifting platform 24 to rise and fall, so as to drive the rotating frame 25 and the limiting block 26 to move. In conjunction with the limiting frame 21, the limiting block 26 and the stretching table 27 move in the horizontal plane. Then, the rubber sealing ring is placed and stretched by the inward and outward contraction of the four stretching tables 27.

[0024] Please see Figure 2In this embodiment, a sliding groove 2 is provided at the lower end of the base body 1, and a support frame 3 is fixedly connected to the rear end of the base body 1. A first hydraulic push rod 4 is installed at the rear end of the support frame 3. The test position is determined by the base body 1 and the support frame 3. A movable frame 5 is fixedly connected to the output end of the first hydraulic push rod 4. A support rod 6 is fixedly connected to the rear end of the movable frame 5. The movable frame 5 and the base body 1 are slidably connected through the sliding groove 2 and the support rod 6. The movable frame 5 is moved by the first hydraulic push rod 4 in conjunction with the sliding groove 2 and the support rod 6. An installation platform 7 is installed at the front end of the movable frame 5. A fixed frame 8 is installed at the upper end of the support frame 3. A second hydraulic push rod 9 is installed at the front end of the fixed frame 8. A limit plate 10 is fixedly connected to the output end of the second hydraulic push rod 9. The limit plate 10 is moved by the second hydraulic push rod 9.

[0025] Please see Figures 2-3 In this embodiment, a mounting frame 11 is slidably connected to the outer side of the limiting plate 10. A pressure plate 12 is installed at the lower end of the mounting frame 11, and a fixing platform 13 is installed at the upper end of the mounting platform 7. The limiting plate 10 supports the mounting frame 11 and the pressure plate 12, so that a pressure testing device can be placed when needed, and the pressure plate 12 can be used to press down and test the compressive deformation resistance of the rubber sealing ring. A mounting plate 14 is installed at the upper end of the fixing platform 13, and a material platform 15 is provided at the upper end of the mounting plate 14. A connecting rod 16 is fixedly connected to the lower end of the material platform 15. The connecting rod 16 is slidably connected to the fixing platform 13 and the mounting plate 14. Next, a rubber sealing ring is placed on the material platform 15 to facilitate observation of the shape change of the rubber sealing ring during the compression test. A support spring 17 is installed between the mounting plate 14 and the material platform 15. A rotating table 18 is rotatably connected to the inner side of the mounting plate 14 through a rotating joint. A scraper body 19 is installed on the outer side of the rotating table 18. The rotating table 18 and the scraper body 19 are rotatably connected to the material platform 15. The material platform 15 is supported by the connecting rod 16 in conjunction with the support spring 17 to support the material platform 15 to return to its original position, which facilitates the addition and removal of the rubber sealing ring. The rotating table 18 and the scraper body 19 are used to scrape off the deformed rubber sealing ring.

[0026] During the pressure deformation test, firstly, the moving frame 5 is moved by the first hydraulic push rod 4 in conjunction with the slide groove 2 and the support rod 6. Then, the fixed platform 13 is placed and installed by the mounting platform 7. Next, the rubber sealing ring is placed in the material platform 15, and the fixed platform 13 is reset by the first hydraulic push rod 4. Then, the pressure testing equipment is installed inside the mounting frame 11, and the limiting plate 10 and the lower pressure platform 12 are moved by the second hydraulic push rod 9 to connect with the material platform 15 and apply pressure to the rubber sealing ring. Finally, the material platform 15 is pressed down, and the deformed rubber sealing ring is scraped off by the rotating platform 18 and the scraper body 19. The material platform 15 is reset by the connecting rod 16 in conjunction with the support spring 17.

[0027] During the tensile deformation test, firstly, the rubber sealing ring is placed using the four inwardly recessed stretching platforms 27, and strain gauges are attached as needed. Next, the power motor 22 drives the threaded rod 23 to rotate, which in turn moves the lifting platform 24 in conjunction with the support platform 20. Then, the lifting platform 24 moves the rotating frame 25 and the limiting block 26, and in conjunction with the limiting frame 21, the limiting block 26 and the stretching platform 27 move in the horizontal plane. Finally, the four stretching platforms 27 are moved outward to stretch the rubber sealing ring, thereby testing the deformation effect of the tensile force on the rubber sealing ring.

[0028] Through the above steps, the limiting frame 21 is installed on the base body 1 and the support platform 20, and the power motor 22 drives the threaded rod 23 to rotate, thereby cooperating with the support platform 20 to drive the lifting platform 24 to rise and fall, so as to drive the rotating frame 25 and the limiting block 26 to move. In conjunction with the limiting frame 21, the limiting block 26 and the stretching platform 27 move in the horizontal plane. Then, by the inward and outward expansion of the four stretching platforms 27, the rubber sealing ring is placed and stretched. This solves the problem that the existing rubber sealing ring detection device has more obstruction on the outer side and the lower end when observing and measuring deformation force, which reduces the effect of observing tensile deformation in all directions and the convenience of force measurement, resulting in a decrease in the use effect and convenience of the rubber sealing ring detection device.
