Description

Technical Field

[0001] This invention relates to the field of fatigue testing technology, and in particular to a linear guide type rubber solvent resistance fatigue tester. Background Technology

[0002] Rubber, as an irreplaceable elastic material, has been used for over 160 years and is widely applied in national defense and economic development. Rubber is not only an indispensable substance in daily life but also a high-performance and functional material essential for the development of advanced technologies. As a highly elastic polymer material with reversible deformation, rubber has gained widespread application due to its excellent elastic properties. In certain important application areas, it is necessary to know various properties of rubber materials, such as tensile strength, compressive strength, flexural strength, torsional strength, fatigue tensile strength, and corrosion resistance. When applied in dynamic environments, the fatigue tensile strength of rubber materials is crucial. The fatigue tensile strength of rubber materials is a quantitative analysis of how many stretches are required for the rubber to fatigue and break under a given stretching stroke; that is, the relationship between the stretching distance and the number of stretches.

[0003] When performing fatigue testing and evaluation, currently available fatigue testing instruments on the market, such as Figure 1 As shown, the concave part is often threadedly connected to the threaded shaft. When the lifting plate / placement plate and the limiting plate rise or fall, the concave part rises and falls synchronously. However, the concave part is equipped with a lower clamping component that clamps the rubber part. The limiting plate is equipped with a cup. When the lifting plate / placement plate, the limiting plate and the concave part rise and fall synchronously, the rubber part is always inside the cup. If it is necessary to replace the rubber part or the solvent resistant material inside the cup, the concave part needs to be removed from the threaded shaft for replacement. Disassembly is inconvenient and the use is cumbersome. Summary of the Invention

[0032] Example 1

[0033] Embodiments of the present invention provide a linear guide type rubber solvent resistance fatigue tester, such as... Figure 2-5 As shown, the device includes a mounting shell 9, a base plate 1 inside the mounting shell 9, a mounting plate 3 fixedly mounted on the base plate 1, a linear guide rail assembly on the front side of the mounting plate 3, an upper clamping assembly 10 mounted on the linear guide rail assembly, two symmetrical mounting blocks 22 fixedly mounted on the rear side of the mounting plate 3, a concave portion 11 mounted on the mounting block 22, a lower clamping assembly 12 mounted on the concave portion 11, the upper clamping assembly 10 and the lower clamping assembly 12 are used to clamp the rubber parts, a lifting assembly is also provided on the rear side of the mounting plate 3, a limiting assembly is provided on the lifting assembly, and a cup body 21 is provided on the limiting assembly.

[0034] Preferably, the linear guide rail assembly includes a drive motor 8, which is fixedly mounted on the base plate 1. A threaded rod 4 is fixedly connected to the upper output end of the base plate 1. Two left-right symmetrical guide rails 6 are also fixedly mounted on the front side of the mounting plate 3. A drive plate 7 is slidably mounted on the guide rails 6. A drive block 2 is fixedly mounted on the front side of the drive plate 7. The threaded rod 4 passes upward through the drive block 2, and the threaded rod 4 is threadedly connected to the drive block 2 at the point where it passes through. The upper end of the threaded rod 4 is rotatably connected to the upper inner wall of the mounting shell 9. An L-shaped connecting plate 5 is fixedly connected to the upper end of the drive plate 7. An upper clamping assembly 10 is fixedly mounted on the lower surface of the horizontal section of the L-shaped connecting plate 5.

[0035] The working principle and beneficial effects of the above technical solution are as follows: The rubber part is clamped onto the upper clamping assembly 10 and the lower clamping assembly 12. Then, the concave part 11 is installed onto the mounting block 22. The cup body 21 is set on the limiting assembly. Solvent-resistant material is poured into the cup body 21. The lifting assembly is started to immerse the rubber part into the cup body 21. Then, the drive motor 8 is started and the threaded rod 4 starts to rotate. The threaded rod 4 drives the drive block 2 to rise. The drive block 2 drives the drive plate 7 to rise. The drive plate 7 drives the L-shaped connecting plate 5 to rise. The L-shaped connecting plate drives the upper clamping assembly 10 to rise, stretching the rubber part. After stretching multiple times, it can be broken.

[0036] By mounting the concave portion 11 onto the mounting block 22, the lower clamping assembly 12 remains stationary and does not move with the lifting assembly. This makes it easier to remove the rubber parts and cup 21, facilitating their replacement and effectively improving the device's convenience. The L-shaped connecting plate 5 is raised by rotating the threaded rod 4, resulting in a simple structure, good lifting stability, and improved safety and stability.

The threaded shafts 20 and the lifting plate 19 are threadedly connected at the passing position. A lifting motor 23 is installed on the lifting plate 19. Two symmetrical first pulleys 50 and two symmetrical second pulleys 24 are also rotatably connected to the lifting plate 19. A belt 25 is wound around the first pulleys 50 and the second pulleys 24. A rotating shaft is fixedly installed on the second pulley 24 on the left. The upper end of the rotating shaft is fixedly connected to the output shaft of the lifting motor 23, and the rotating shaft is rotatably connected to the lifting plate 19. The upper end of the threaded shaft 20 passes through the center position of the first pulley 50, and the threaded shaft 20 is threadedly connected to the first pulley 50.

[0040] Preferably, a cylinder 29 is fixedly mounted on the lifting plate 19, and a rotating plate 30 is rotatably mounted on the lifting plate 19. Several evenly distributed connecting rods 31 are hinged to the rotating plate 30. A slider 33 is hinged to the other end of the connecting rod 31. The slider 33 is slidably mounted on the track 32, which is fixedly mounted on the lifting plate 19. A clamping rod 13 is fixedly mounted on the upper end of the slider 33. The clamping rod 13 passes upward through the through groove 27 and is slidably connected to the through groove 27. The output end of the cylinder 29 is fixedly connected to the rear side of the middle slider 33.

[0041] Even when the slider 33 moves to the furthest position from the center of the limiting plate 14, the connecting rod 31 and the track 32 are not on the same straight line.

[0042] The working principle and beneficial effects of the above technical solution are as follows: the cylinder 29 is started, the cylinder 29 drives the central slider 33 to move on the track 32, the central slider 33 drives the central clamping rod 13 to move towards the center of the limiting plate 14, the central slider 33 drives the central connecting rod 31 to deflect, thereby driving the rotating plate 30 to rotate, the rotating plate 30 drives the remaining connecting rods 31 to deflect, the remaining connecting rods 31 drive the remaining sliders 33 to move towards the center of the limiting plate 14, thereby making the clamping rod 13 on the slider 33 clamp the cup body 21;

[0043] Start the lifting motor 23. The lifting motor 23 drives the rotating shaft to rotate. The rotating shaft drives the second pulley 24 to rotate. The second pulley 24 drives the first pulley 50 to rotate through the belt 25. The first pulley 50 drives the threaded shaft 20 to rotate. The threaded shaft 20 drives the lifting plate 19 to rise. After the cup body 21 is raised to the appropriate position, it is ready.

[0044] The cylinder 29 drives the central slider 33 to rotate, thereby causing the rotating plate 30 to rotate. This allows the clamping rod 13 to clamp the cup body 21. The structure is simple, easy to use, and the clamping force is stable.

The structure is simple, easy to use, and can effectively improve the safety and stability of the structure.

[0045] Example 3

[0046] Based on the above embodiment 1, as follows Figure 5 , 8As shown in -11, the lifting assembly includes a drive motor 51 and two symmetrical rotating shafts 55. The rotating shafts 55 are threaded. The lower end of the right rotating shaft 55 is fixedly connected to the output end of the drive motor 51.

[0047] Preferably, the limiting component includes two symmetrical fixing plates 41, which are fixedly mounted on the placement plate 54.

The cup body 21 has a first groove on both the front and rear sides, and the limiting block 26 cooperates with the first groove.

[0048] Preferably, auxiliary components are symmetrically arranged on the side of the clamping plates 36 that are close to each other. The auxiliary components include two L-shaped slide grooves 37 that are symmetrical front to back. The side of the L-shaped slide grooves 37 that is far from each other is fixedly arranged on the side of the clamping plates 36 that are close to each other. Slide rods 42 are slidably arranged in the L-shaped slide grooves 37. The top ends of the two slide rods 42 are fixedly connected to the moving plate 39. Two L-shaped racks 40 that are symmetrical front to back are fixedly arranged on the side of the moving plate 39 that is close to each other. Four evenly distributed gears 43 are provided on the placement plate 54. The L-shaped racks 40 mesh with the gears 43. An auxiliary plate 38 is fixedly arranged on the gears 43. The cup body 21 has second grooves on the left and right sides. The auxiliary plate 38 cooperates with the second grooves.

[0049] Preferably, a protective box 35 is fixedly provided on one side of the fixed plates 41 that are close to each other. A plurality of protective springs 46 are provided inside the protective box 35. The protective springs 46 are fixedly provided on the inner wall of the protective box 35 that is far from each other. The other end of the protective springs 46 is fixedly connected to a sliding plate. The sliding plate is slidably connected to the inner wall of the protective box 35. A connecting block 15 is fixedly provided on one side of the sliding plates that are close to each other. The other end of the connecting block 15 is fixedly connected to a slider 16. The slider 16 is slidably connected to the inner wall of the protective box 35. An opening is provided on the side wall of the protective box 35 that is far from each other. The slider 16 extends out of the protective box 35 from the opening. A protective plate 17 is fixedly connected on the side of the slider 16 that is close to each other. The protective plate 17 is located on the upper side of the cup body 21. The protective plate 17 is square. An arc groove is provided on the side of the protective plate 17 that is close to each other.

[0050] Preferably, the protective box 35 is further provided with a movable rod 45, which extends downward out of the protective box 35. A first trapezoidal block 44 is fixedly provided on the movable rod 45. A locking block 47 is fixedly provided on the side of the upper end of the movable rod 45 that is close to each other. A limiting groove 49 is provided on the lower inner wall of the protective box 35. A release spring 48 is fixedly provided at the lower end of the locking block 47. The lower end of the release spring 48 is fixedly connected in the limiting groove 49, and the locking block 47 cooperates with the limiting groove 49.

A second trapezoidal block 18 is provided on the side of the driving rod 28 that is far away from each other, and the second trapezoidal block 18 cooperates with the first trapezoidal block 44.

[0051] The working principle and beneficial effects of the above technical solution are as follows: The cup body 21 is placed on the placement plate 54, the cup body 21 squeezes the clamping plate 36, the clamping spring 34 is compressed, the limiting block 26 enters the first groove, and the slide rod 42 slides in the L-shaped slide groove 37. When the cup body 21 completes the squeezing of the clamping plate 36 (at this time, the cup body 21 has not yet descended to the contact position with the placement plate 54, and will not affect the movement of the L-shaped rack 40), the L-shaped slide groove 37 moves into place, the two moving plates 39 move in opposite directions, the moving plates 39 drive the L-shaped rack 40 to move, the L-shaped rack 40 drives the gear 43 to rotate, and the gear 43 drives the auxiliary plate 38 to enter the second groove to complete the limiting.

[0052] When the cup body 21 presses against the clamping plate 36, the drive rod 28 moves in the opposite direction, causing the second trapezoidal block 18 to move in the opposite direction. The second trapezoidal block 18 cooperates with the first trapezoidal block 44 to move the moving rod 45 downward, releasing the compression of the spring 48. The locking block 47 enters the limiting groove 49, and the moving rod 45 no longer limits the sliding plate. The protective spring 46 resets, causing the sliding plates, connecting block 15, slider 16 and protective plate 17 on both sides to move towards each other. The protective plate 17 first contacts the outer wall of the cup body 21. When the cup body 21 descends to the contact position with the placement plate 54, the protective plate 17 is exactly above the cup body 21.

[0053] By cooperating with the clamping plate 36, the limiting block 26, and the cup body 21, the cup body 21 can be clamped. Further limiting is achieved by the auxiliary plate 38 cooperating with the cup body 21. The sliding rod 42 slides within the L-shaped groove 37. When the moving plate 39 begins to move in the opposite direction, the moving plate 39 restricts the movement of the L-shaped groove 37, preventing it from moving and thus fixing the cup body 21, making its limiting more stable. The protective plate 17 prevents some of the solvent from ejecting from the cup body 21 when the rubber component breaks, effectively improving safety. The cooperation between the second trapezoidal block 18 and the first trapezoidal block 44, and the cooperation between the locking block 47 and the limiting groove 49, allows the protective plate 17 to eject when the cup body 21 presses against the clamping plate 36, making the structure more innovative and practical.

[0054] Example 4

[0055] Based on any one of the above embodiments 1-3, the linear guide type rubber solvent resistance fatigue tester further includes:

[0056] Speed ​​sensor: mounted on drive board 7, used to detect the moving speed of drive board 7;

[0057] Speed ​​sensor: mounted on threaded rod 4, used to detect the rotational speed of threaded rod 4;

[0058] Displacement sensor: mounted on the drive board 7, used to detect the movement displacement of the drive board 7;

[0059] Timer: Installed on drive motor 8, used to detect the working time of drive motor 8;

[0060] The controller and alarm are respectively installed on the base plate 1. The controller is electrically connected to the speed sensor, rotation speed sensor, displacement sensor, timer, and alarm. The controller controls the alarm based on the speed sensor, rotation speed sensor, displacement sensor, and timer, including the following steps:

[0061] Step 1: The controller obtains the lifting state index of the linear guide assembly based on the speed sensor, rotation speed sensor, displacement sensor, timer, and formula (1):

[0062]

[0063] Where K is the lifting state index of the linear guide assembly; δ is the mechanical efficiency of the drive motor 8; π is pi; r is the radius of the threaded rod 4; n is the value detected by the speed sensor; v is the value detected by the velocity sensor; T is the value detected by the timer; L is the value detected by the displacement sensor; and L1 is the length of the guide rail 6.

[0064] Step 2: Compare the lifting state index of the linear guide assembly calculated by formula (1) with the corresponding preset lifting state index. When the lifting state index of the linear guide assembly calculated by formula (1) is less than the corresponding preset lifting state index, the controller controls the alarm to sound.

[0065] The working principle and beneficial effects of the above calculation scheme are as follows: First, the lifting state index of the linear guide assembly is calculated using formula (1). The controller compares the lifting state index of the linear guide assembly calculated by formula (1) with the corresponding preset lifting state index. When the lifting state index of the linear guide assembly calculated by formula (1) is less than the corresponding preset lifting state index, the controller controls the alarm to sound. When the calculated lifting state index of the linear guide assembly is less than the corresponding preset lifting state index, the controller prompts the personnel that there is a problem with the linear guide assembly of this tester. The personnel should check in time whether the drive motor 8 is working properly, whether the connection between the threaded rod 4 and the drive block 2 is normal, and whether the sliding between the drive plate 7 and the guide rail 6 is normal. After the inspection is completed, the drive motor 8 continues to work, and the controller connects the speed sensor, rotation speed sensor, displacement sensor, timer and alarm to monitor the working state index of the tester. In addition, by setting the alarm to realize the alarm and remind the personnel to check the problems in time, the failure of the linear guide assembly can be effectively reduced, and the practicality can be effectively improved.

If these modifications and variations fall within the scope of the claims of this invention and their equivalents, then this invention is also intended to include these modifications and variations.
