[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a rubber sealing ring testing device, including a main base plate 1, a supporting base column 2, an upper base plate 3, and a positioning mold 4. The supporting base column 2 is fixedly installed on the upper end of the main base plate 1, and the upper base plate 3 is fixedly installed on the upper end of the supporting base column 2. The positioning mold 4 is provided on the upper end of the upper base plate 3. The surface of the positioning mold 4 is provided with a sealing ring groove 5 adapted to the sealing ring. The lower end of the upper base plate 3 is provided with a push rod 9 for lifting the sealing ring, and the upper end of the main base plate 1 is provided with a tool for moving the push rod 9. The pusher 17 and the upper end of the base plate 3 are equipped with a pusher plate 23 for pushing the sealing ring. After the rubber sealing ring testing device is completed, when it is necessary to remove the rubber sealing ring from the sealing ring slot 5, the pusher 17 is pressed down and the push rod 9 pushes the rubber sealing ring out, realizing the quick removal of the rubber sealing ring. During the process of pushing out the rubber sealing ring, the pusher plate 23 moves at the same time to push the rubber sealing ring that has been pushed out to one side, so that the testing personnel can directly place the next rubber sealing ring, further improving the testing efficiency.

[0023] Please see Figure 1 and Figure 2In this embodiment, a guide shaft 6 is fixedly installed on the upper end of the main base plate 1. A slider 7 is slidably connected to the surface of the guide shaft 6. A base 8 is fixedly installed on the upper end of the slider 7. A push rod 9 is fixedly installed on the upper end of the base 8. A through hole 25 is provided on the surface of the sealing ring groove 5. The push rod 9 is adapted to the through hole 25. The through hole 25 is evenly distributed in an annular shape. A rack 10 is fixedly connected to one side of the slider 7. A bearing seat 11 is fixedly installed on the upper end of the main base plate 1. A gear 12 is rotatably connected between the two bearing seats 11. A support frame 13 is fixedly installed on the upper end of the main base plate 1. A flange bearing 14 is fixedly installed on the upper end of the support frame 13. A guide shaft 15 is slidably connected to the end of the flange bearing 14. A gear is fixedly installed between the two guide shafts 15. Rack 2 16 and pusher 17 are fixedly installed on one side of rack 2 16. When in use, the rubber sealing ring to be tested is first placed into the sealing ring slot 5 on the surface of the positioning mold 4. The sealing ring is judged to be qualified by observing the deformation state of the rubber sealing ring and the magnitude of the fitting resistance. After the test is completed, when it is necessary to remove the rubber sealing ring from the sealing ring slot 5, pusher 17 is pressed down, rack 2 16 moves down, and rack 10 connected to gear 12 moves up at the same time, thereby driving slider 1 7 to slide on the surface of guide shaft 1 6. The push rod 1 9 provided at the upper end of slider 1 7 passes through the through hole 25 provided on the surface of sealing ring slot 5. Push rod 1 9 pushes the rubber sealing ring out of sealing ring slot 5, thereby realizing the quick removal of rubber sealing ring.

[0024] Please see Figure 3 - Figure 5In this embodiment, a push rod 18 is fixedly connected to the upper end of slider 1 7. The upper end of push rod 18 passes through the upper base plate 3. A push block 19 is fixedly connected to the upper end of push rod 18. One side of push block 19 is an inclined surface. A guide shaft 20 is fixedly installed on the upper end of the upper base plate 3. Slider 21 is slidably connected to the surface of guide shaft 20. A roller seat 22 is fixedly installed between the two sliders 21. A push plate 23 is fixedly installed on one side of roller seat 22. The roller surface of roller seat 22 contacts the inclined surface of push block 19. Push block 19 is used to push push plate 23 to move. A spring 24 is sleeved on the surface of guide shaft 20. Spring 24 is used for resetting. Positioning holes 26 are provided at the four corners of the lower end of positioning mold 4. The lower edge of positioning hole 26 is rounded. An installation groove is provided on the surface of upper base plate 3. Limiting rods 27 are provided at the four corners of the installation groove of upper base plate 3. The upper end of the positioning rod 27 is rounded. The positioning rod 27 is slidably connected to the positioning hole 26. During the process of ejecting the rubber sealing ring, the inclined surface on one side of the push block 19 moves upward and, through the squeeze roller bearing seat 22, pushes the ejected rubber sealing ring to one side via the push plate 23. This allows the inspector to directly place the next rubber sealing ring, further improving the inspection efficiency. The rubber sealing rings pushed to one side can be collected later. When different rubber sealing rings need to be inspected and the positioning mold 4 needs to be replaced, the positioning mold 4 is taken out from the mounting groove on the surface of the upper base plate 3, and the positioning hole 26 at the lower end of the new positioning mold 4 is aligned with the positioning rod 27. After the positioning rod 27 and the positioning hole 26 are matched, the positioning mold 4 is installed. The lower edge of the positioning hole 26 is rounded, which facilitates the matching of the positioning hole 26 and the positioning rod 27.

[0025] In use, the rubber sealing ring to be tested is first placed into the sealing ring slot 5 on the surface of the positioning mold 4. The quality of the sealing ring is determined by observing its deformation and the resistance to placement. After the test, when the rubber sealing ring needs to be removed from the sealing ring slot 5, the pusher 17 is pressed down. The pusher 17 is fixedly installed on one side of the rack 16. The rack 16 moves downward, and the gear 12, which meshes with the rack 16, rotates at the bearing seat 11. The rack 10, which meshes with the gear 12, moves upward. The rack 10 is fixedly connected to one side of the slider 7. The slider 7 slides on the surface of the guide shaft 6. The upper end of the slider 7 is fixedly installed with a base 8. The upper end of the base 8 is fixedly installed with a push rod 9. The push rod 9 passes through the through hole 25 on the surface of the sealing ring slot 5. The push rod 9 pushes the rubber sealing ring out of the sealing ring slot 5, thereby realizing the quick removal of the rubber sealing ring.

[0026] When rack 2 16 moves, guide shafts 2 15 fixedly installed on both sides of rack 2 16 slide simultaneously at flange bearings 14 fixedly installed on the upper end of support frame 13, thereby ensuring the stability of rack 2 16. Push rod 1 9 is evenly distributed in a ring, so that when push rod 1 9 pushes out the rubber sealing ring, push rod 1 9 can evenly support the rubber sealing ring, thereby ensuring that the rubber sealing ring will not be damaged during the pushing process.

[0027] During the process of ejecting the rubber sealing ring, the push rod 18 fixedly installed on the upper end of the slider 1 7 moves upward simultaneously. The upper end of the push rod 18 is fixedly connected to the push block 19. As the inclined surface on one side of the push block 19 moves upward, it pushes the ejected rubber sealing ring to one side through the squeeze roller bearing 22. This allows the inspection personnel to directly place the next rubber sealing ring, further improving the inspection efficiency. The rubber sealing rings pushed to one side can be collected in a centralized manner later.

[0028] When different rubber seals need to be tested and the positioning mold 4 needs to be replaced, the positioning mold 4 is taken out from the mounting groove on the surface of the upper base plate 3, and the positioning hole 26 at the lower end of the new positioning mold 4 is aligned with the limiting rod 27. After the limiting rod 27 is adapted to the positioning hole 26, the positioning mold 4 is installed. The lower edge of the positioning hole 26 is rounded, which facilitates the adaptation of the positioning hole 26 and the limiting rod 27, and improves the installation speed of the positioning mold 4 while ensuring installation accuracy.

[0029] Through the above steps, after the rubber sealing ring detection device has completed the test, when it is necessary to remove the rubber sealing ring from the sealing ring slot 5, the pusher 17 is pressed down, and the push rod 19 passes through the through hole 25 provided on the surface of the sealing ring slot 5, thereby pushing out the rubber sealing ring, realizing the rapid removal of the rubber sealing ring and greatly improving the detection efficiency. During the process of pushing out the rubber sealing ring, the push plate 23 moves at the same time to push the rubber sealing ring that has been pushed out to one side, so that the testing personnel can directly place the next rubber sealing ring, further improving the detection efficiency. The rubber sealing rings pushed to one side can be collected in a centralized manner later.
