[0002] A rubber gasket is a thin rubber product that seals between two static surfaces of a metal flange or other connection parts. Rubber gaskets have properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance, which enable them to maintain a stable sealing effect in various harsh environments. In addition, rubber gaskets also need to have a certain tensile resistance.

A rotating motor 50 is fixedly connected to one end of the rectangular plate 44, and the output shaft of the rotating motor 50 is fixedly connected to the threaded rod 46. The compressive strength testing mechanism can perform compressive strength tests on the front and back sides of the rubber gasket 43.

[0031] In this embodiment, the auxiliary observation mechanism specifically includes: a support seat 51 fixed on the outer side surface of the concave plate 5.

[0032] In this embodiment, the length of the material receiving rod 40 matches the thickness of the rubber gasket 43 to be tested, and the diameter of the rubber gasket 43 is larger than the thickness of the strip-shaped plate 39. This setting ensures that the rubber gasket 43 can be successfully clamped by the clamping assembly.

[0033] In this embodiment, one end of the material receiving rod 40 is fixedly connected with an anti - detachment round head 41.

[0034] In this embodiment, the driving assembly specifically includes: a support plate 26 located inside the workbench 1. There are connecting blocks 27 fixedly connected between the corner positions of the top surface of the support plate 26 and the workbench 1. And one side of the bottom end surface of the support plate 26 is fixedly connected with a driving motor 28.

And a second pulley 30 is rotatably connected to one side of the first pulley 29. There is a first transmission belt 31 connecting the first pulley 29 and the second pulley 30.

And the third pulley 32 is fixedly connected to the second pulley 30. A first guide wheel 34 is movably connected to one side of the third pulley 32, and a second guide wheel 33 is movably connected to the other side of the third pulley 32. One side inside the support frame 2 is rotatably connected with a lead screw 21. And the bottom end of the lead screw 21 penetrates through the workbench 1 and is fixedly connected with a fourth pulley 22. The two lead screws 21 penetrate through the lifting plate 3 and are thread - connected thereto. There is a second transmission belt 35 connecting the two fourth pulleys 22 and the third pulley 32. And the second transmission belt 35 passes through the first guide wheel 34 and the second guide wheel 33.

By setting the driving assembly, the stability of the up - and - down movement of the lifting plate 3 can be effectively improved, and it has a fast response speed. At the same time, high - precision positioning and control can be achieved.

[0035] In this embodiment, the limiting and stabilizing mechanism specifically includes: two parallel optical axes 23 fixed inside the support frame 2. Guide plates 24 are fixedly connected to the corner positions of the outer side surface of the lifting plate 3. And arc - shaped grooves 25 matching the optical axes 23 are opened on the outer side surfaces of the guide plates 24. The optical axes 23 are in contact with and movably connected to the arc - shaped grooves 25. The limiting and stabilizing mechanism can further improve the stability of the up - and - down movement of the lifting plate 3.

[0036] In this embodiment, a control console 20 is fixedly connected to one side of the top surface of the workbench 1. The control console 20 is electrically connected to the driving motor 28, the stepping motor 36, and the axial - flow fan 42, and can control their operating states.

[0037] The working principle of the present invention is as follows: The test device for the performance of the rubber gasket has two working modes when in use. In the first working mode, the rubber gasket 43 is first subjected to a tensile test and then a compressive test. In the second working mode, the rubber gasket 43 is first subjected to a compressive test and then a tensile test. These two working modes can better simulate the test states of the rubber gasket 43 under different working conditions and have high adaptability.

[0038] The specific working process of the first working mode is as follows: First, the stepping motor 36 of the loading and unloading component runs to drive the rotating shaft 38 to rotate clockwise by 90 degrees. Subsequently, the staff puts the first rubber gasket 43 to be tested on the receiving rod 40 on the side far from the support frame 2. During this process, the rubber gasket 43 passes over the anti - detachment round head 41, and the anti - detachment round head 41 plays a certain limiting role on the rubber gasket 43. Then, the driving component runs to raise the lifting plate 3 to a preset position. Specifically, the driving motor 28 runs to drive the first pulley 29 to rotate. The first pulley 29 drives the second pulley 30 to rotate through the first transmission belt 31. The second pulley 30 drives the third pulley 32 to rotate. The third pulley 32 drives the two fourth pulleys 22 to rotate synchronously through the second transmission belt 35. During this process, the first guide pulley 34 and the second guide pulley 33 play a guiding role on the second transmission belt 35. The fourth pulley 22 rotates to drive the lead screw 21 connected to it to rotate, and the lifting plate 3 slowly rises along the two lead screws 21. During this process, the optical axis 23 and the arc - shaped groove 25 of the guide plate 24 have relative displacement, effectively improving the stability of the up - and - down movement of the lifting plate 3. After the lifting plate 3 rises to the preset position, the stepping motor 36 of the loading and unloading component runs to drive the rotating shaft 38 to rotate clockwise by 180 degrees. At this time, the first rubber gasket 43 to be tested is just located between the two clamping components.

[0039] Next, the staff clamps the upper and lower ends of the rubber gasket 43 through two clamping components. Specifically, the handle 17 of the upper clamping component is pushed upward, and the handle 17 of the lower clamping component is pushed downward. When the handle 17 is pushed, the fan gear 16 connected to it rotates relatively around the rotating groove 18. Since the fan gear 16 is meshed with the teeth 15 on the lifting rod 14, the rotation of the fan gear 16 drives the lifting rod 14 to move relatively along the lifting groove 13, and the disk body 19 connected to the lifting rod 14 moves accordingly, thereby driving the clamping block 9 to move along the telescopic groove 8. The two clamping blocks 9 in the same telescopic groove 8 approach each other due to the action of the inclined surface during the movement process, until the two clamping blocks 9 extend out of the telescopic groove 8 and clamp the first rubber gasket 43 to be tested. At this time, the rubber gasket 43 is just clamped in the card slot 11. It should be noted that when the clamping assembly clamps the rubber gasket 43, the front and back pressure resistance of the rubber gasket 43 can be directly tested by adjusting the clamping force, that is, continuing to pull the handle 17, and the applicability is relatively high. After the rubber gasket 43 is clamped, the stepper motor 36 of the loading and unloading assembly drives the rotating shaft 38 to rotate counterclockwise by ninety degrees. At this time, the rubber gasket 43 is separated from the material receiving rod 40, and the two strip plates 39 rotate into the through groove 37. Subsequently, the first rubber gasket 43 is subjected to a tensile test, that is, the driving assembly is operated to move the lifting plate 3 downward. During the process, the clamping assembly below stretches the rubber gasket 43. After the tensile test is completed, the driving assembly is operated again to raise the lifting plate 3 to the preset position. Subsequently, the stepper motor 36 of the loading and unloading assembly is operated to drive the rotating shaft 38 to rotate clockwise by ninety degrees. At this time, the material receiving rod 40 passes through the rubber gasket 43 and sleeves it on the outside. Next, the staff member loosens the first rubber gasket 43 by turning the handle 17, and at the same time, the staff member puts the second rubber gasket 43 on another receiving rod 40. Then, the stepper motor 36 drives the rotating shaft 38 to rotate ninety degrees clockwise, and the first rubber gasket 43 is located in the through groove 37. Then, the compression test mechanism is used to perform a compression test on it. Specifically, the rotating motor 50 drives the threaded rod 46 to rotate, and the moving seat 47 in the rectangular groove 45 moves toward the concave plate 5 along the threaded rod 46. During the process, the pressing cylinder 48 moves with it, and the rubber gasket 43 gradually enters the circular groove 49 of the pressing cylinder 48. As the pressing cylinder 48 continues to move, the inner wall of the circular groove 49 presses against the rubber gasket 43 to perform a compression test on it. After the compression test is completed, the compression test mechanism is restored to its initial position, and the stepper motor 36 drives the rotating shaft 38 to rotate ninety degrees clockwise. At this time, the second rubber gasket 43 reaches the clamping position, and the first rubber gasket 43 reaches the position horizontally aligned with the circular lens 55 of the auxiliary observation mechanism.Subsequently, the test results of the first rubber gasket 43 are observed through the auxiliary observation mechanism. Specifically, the cylinder 52 operates to extend the output shaft, driving the connecting seat 53 and the annular plate 54 to approach the first rubber gasket 43. When the output shaft of the cylinder 52 extends to the maximum length, the annular plate 54 just fits over the outside of the first rubber gasket 43. At this time, the staff can carefully observe the deformed state of the first rubber gasket 43 after the test through the scale bar on the circular lens 55, and judge whether the performance of the first rubber gasket 43 is qualified based on this. After the observation is completed, the auxiliary observation mechanism is restored to the initial position, and then the second rubber gasket 43 is clamped by the two clamping components to start the second round of testing, and so on until the testing and observation of all rubber gaskets 43 are completed. It should be noted that during the testing process, the axial fans 42 above and below the through groove 37 form air convection on both sides inside the through groove 37. Each time the rubber gasket 43 and the material receiving rod 40 pass through the through groove 37, they will be cleaned by the air convection, avoiding the influence of attached debris on the test effect and improving the test accuracy.

[0040] The specific working process of the second working mode is as follows: First, the stepping motor 36 of the loading and unloading component operates to drive the rotating shaft 38 to rotate counterclockwise by ninety degrees. Subsequently, the staff puts the first rubber gasket 43 to be tested on the material receiving rod 40 on the side away from the support frame 2. Then, the driving component operates to raise the lifting plate 3 to the preset position, and the stepping motor 36 of the loading and unloading component operates to drive the rotating shaft 38 to rotate counterclockwise by ninety degrees. At this time, the first rubber gasket 43 to be tested is just located in the through groove 37, and then the compressive test mechanism conducts a compressive test on it. After the compressive test is completed, the compressive test mechanism is restored to the initial state, and the stepping motor 36 operates to drive the rotating shaft 38 to rotate counterclockwise by ninety degrees. At this time, the first rubber gasket 43 to be tested is just located between the two clamping components.

[0041] Subsequently, the staff clamped the upper and lower ends of the rubber gasket 43 through two clamping assemblies. After the rubber gasket 43 was clamped, the stepping motor 36 of the loading and unloading assembly ran to drive the rotating shaft 38 to rotate counterclockwise by 90 degrees. At this time, the rubber gasket 43 was separated from the receiving rod 40, and the two strip plates 39 rotated into the through groove 37. Subsequently, a tensile test was carried out on the first rubber gasket 43. After the tensile test was completed, the stepping motor 36 of the loading and unloading assembly ran to drive the rotating shaft 38 to rotate clockwise by 90 degrees. The receiving rod 40 passed through the rubber gasket 43 and sleeved it outside. Immediately afterwards, by pulling the handle 17, the clamping assembly released the first rubber gasket 43. At the same time, the staff sleeved the second rubber gasket 43 on another receiving rod 40. Subsequently, the stepping motor 36 ran to drive the rotating shaft 38 to rotate clockwise by 180 degrees. At this time, the second rubber gasket 43 reached the position to be clamped, and the first rubber gasket 43 reached the position horizontally aligned with the circular lens 55 of the auxiliary observation mechanism.
