Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring press-fitting technology, specifically to a spring press-fitting device for motorcycle shock absorbers. Background Technology
[0002] The working process of a motorcycle shock absorber is divided into two stages. In the compression stage, the shock absorber cylinder moves downward and the piston moves upward relative to the compression spring. The hydraulic fluid flows rapidly through the piston valve and the small hole at the bottom, reducing the impact force. In the rebound stage, the piston moves downward, causing the valve to close. The hydraulic fluid can only flow through a smaller damping orifice, increasing the flow resistance and effectively suppressing the spring rebound speed. The damping effect converts more than 80% of the mechanical energy generated by the friction of the hydraulic fluid flow into heat energy. Through graded damping control, it ensures that the tire always maintains contact with the ground.
[0003] Before installing a motorcycle shock absorber, the shock absorber spring usually needs to be preloaded. Preloading is to maintain the initial support force of the suspension system and improve the safety of the motorcycle. In current technology, the spring is usually pressed in by twisting the nut on one side of the damper. The spring tension is changed by rotating the nut. When pressing the spring in with the nut, the worker also needs to use a tape measure to continuously measure the length of the spring and adjust the spring length to achieve the required preload. This takes a lot of time to adjust the spring length, which affects the worker's work efficiency. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example: Reference Figure 1 , Figure 2 , Figure 4 and Figure 9A spring press-fitting device for a motorcycle shock absorber includes a support base 1. A shock absorber telescopic rod 17 is movably sleeved on the top of the support base 1. A shock absorber spring 16 is movably sleeved on the outer circular wall of the shock absorber telescopic rod 17. Two sliding grooves 2 are formed on the top of the support base 1. A positioning rod 3 is slidably connected inside the sliding grooves 2. A pressing plate 21 is movably sleeved on the top of the positioning rod 3. A limiting plate 19 is movably sleeved on the bottom of the pressing plate 21. Two clamping plates 18 are provided on the top of the support base 1. The interiors of the two clamping plates 18 are movably sleeved with the limiting plate 19. The outer circular wall of 19 is provided with a scale. The top of the support base 1 is provided with a rotating component. The top of the pressing plate 21 is provided with a pressing component. One side of the positioning rod 3 is provided with a snap-fit component. The pressing component includes a hydraulic rod 22. The hydraulic rod 22 is provided on the top of the pressing plate 21. The telescopic rod of the hydraulic rod 22 is fixedly connected to the pressing plate 21. The top of the two positioning rods 3 is fixedly connected with a support plate 23. The hydraulic rod 22 is fixedly connected to the support plate 23. The top of the pressing plate 21 is provided with a positioning hole 30. The inner circular wall of the positioning hole 30 is movably sleeved with the shock absorber telescopic rod 17.
[0028] When the hydraulic rod 22 begins to press the shock absorber spring 16, it is activated, generating a force that moves the pressure plate 21 closer to the support base 1. This causes the shock absorber telescopic rod 17 to pass through the positioning hole 30. At this time, the shock absorber spring 16 and the limiting plate 19 move closer to the support base 1. The displacement of the limiting plate 19 can be determined by the scale lines on it, thus obtaining the displacement of the shock absorber spring 16. When the pressing requirement is met, the operation of the hydraulic rod 22 is stopped, completing the pressing of the shock absorber spring 16 by the hydraulic rod 22. This allows the operator to easily open or close the hydraulic rod 22 at any time to control the displacement of the shock absorber spring 16.
[0029] refer to Figure 1 , Figure 3 and Figure 9The rotating assembly includes a support block 4, which is located on top of the support base 1. A lead screw 6 is provided on one side of the support block 4 and passes through it. A rotating block 5 is fixedly connected to the end of the lead screw 6 away from the clamping plate 18. A slider 7 is threadedly connected to the outer circular wall of the lead screw 6. Fixed blocks 8 are fixedly connected to both sides of the support block 4. A fixed column 9 is fixedly connected to the top of the fixed block 8. A rotating rod 10 is movably sleeved on the outer circular wall of the fixed column 9. A movable block 13 is movably sleeved on the outer circular wall of the rotating rod 10. The two movable blocks... A fixed rod 11 is movably connected between 13 and passes through the movable block 13. The fixed rod 11 is fixedly connected to the slider 7. A connecting rod 14 is fixedly connected to the end of the rotating rod 10 away from the fixed column 9. The connecting rod 14 is fixedly connected to the bottom of the clamping plate 18. Limiting plates 12 are fixedly connected to both ends of the fixed rod 11. A limiting block 15 is fixedly connected to the end of the lead screw 6 away from the rotating block 5. Two first springs 20 are fixedly connected to the bottom of the limiting plate 19. The inner bottom surface of the clamping plate 18 is fixedly connected to the two first springs 20.
[0030] Before pressing the shock absorber spring 16, the rotating block 5 is rotated counterclockwise via the set rotating block 5. Then, the lead screw 6 starts to rotate counterclockwise. The rotation of the lead screw 6 causes the slider 7 and the fixed rod 11 to move closer to the support block 4. Then, the two moving blocks 13 and the two fixed blocks 8 move away from the slider 7. Subsequently, the two connecting rods 14, the two clamping plates 18, and the two limiting plates 19 move away from the shock absorber telescopic rod 17. At this time, the shock absorber spring 16 and the shock absorber telescopic rod 17 are placed on top of the support base 1. When the pressing plate 21 begins to pre-compress the shock absorber spring 16, the support block 4 is rotated clockwise. Then, the lead screw 6 starts to rotate clockwise. Rotation causes slider 7 and fixed rod 11 to move away from support block 4. Subsequently, two moving blocks 13 and two fixed blocks 8 move closer to slider 7, driving two connecting rods 14, two clamping plates 18 and two limiting plates 19 to move closer to shock absorber telescopic rod 17. When the two clamping plates 18 are in close contact, rotation of rotating block 5 stops. At this time, the two clamping plates 18 and the two limiting plates 19 are in close contact, completing the limiting of the spring. This allows the operator to read the scale of the limiting plate 19 at this time, so that the operator can keep track of the displacement of the limiting plate 19 during the subsequent pressing of the shock absorber spring 16 by the pressing plate 21, and thus determine the degree of compression of the shock absorber spring 16.
[0031] refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8The snap-fit assembly includes two limiting holes 26, which are respectively set on one side of the two positioning rods 3. A second spring 27 is fixedly connected to one side of the inner side of the limiting hole 26. A locking block 28 is fixedly connected to the end of the second spring 27 away from the positioning rod 3. Two fixing holes 25 are opened on one side of the inner side of the slide groove 2. The fixing holes 25 are movably snap-fitted with the locking block 28. A movable plate 29 is fixedly connected to the side of the positioning rod 3 away from the second spring 27. A limiting groove 24 is opened on the inner side of the slide groove 2 near the movable plate 29. The movable plate 29 is slidably connected to the limiting groove 24.
[0032] Before pressing the shock absorber spring 16, the positioning rods 3 are pulled to move them away from the clamping plate 18. At this time, the locking block 28 is subjected to a force close to the positioning rods 3, causing it to move closer to the limiting hole 26. Subsequently, the second spring 27 moves closer to the limiting hole 26. Meanwhile, the moving plate 29 slides away from the clamping plate 18 inside the limiting groove 24. When the positioning rods 3 reach the end of the slide groove 2, the pulling of the positioning rods 3 stops. Then, the force generated by the deformation of the limiting hole 26 causes the locking block 28 to move closer to the fixing hole 25, thus completing the limiting of the positioning rods 3. This allows the shock absorber spring 16 and the shock absorber telescopic rod 17 to be placed on top of the support base 1. After the shock absorber telescopic rod 17 is placed on top of the support base 1, the positioning rod 3 is pushed, causing the two positioning rods 3 to move towards the clamping plate 18. At this time, the locking block 28 is subjected to the force of the positioning rod 3, and then the locking block 28 moves towards the limiting hole 26. Subsequently, the second spring 27 moves towards the limiting hole 26. At this time, the moving plate 29 slides towards the clamping plate 18 inside the limiting groove 24. When the positioning rod 3 moves to the top of the slide groove 2, the pulling of the positioning rod 3 stops. Then, the force generated by the deformation of the limiting hole 26 causes the locking block 28 to move towards the fixing hole 25. By adjusting the position of the positioning rod 3, it is convenient to adjust the position of the pressing plate 21 by moving the positioning rod 3, so that the pressing plate 21 can press the shock absorber spring 16.
[0033] Working principle: Please refer to Figures 1-9As shown, when the hydraulic rod 22 begins to press the shock absorber spring 16, it is activated, generating a force that moves the pressure plate 21 closer to the support base 1. This causes the shock absorber telescopic rod 17 to pass through the positioning hole 30. At this time, the shock absorber spring 16 and the limiting plate 19 move closer to the support base 1. The displacement of the limiting plate 19 can be determined by the scale lines on the limiting plate 19, thus obtaining the displacement of the shock absorber spring 16. When the pressing requirement is met, the operation of the hydraulic rod 22 is stopped, completing the pressing of the shock absorber spring 16 by the hydraulic rod 22. This allows the displacement of the shock absorber spring 16 to be obtained by the scale on the outer wall of the limiting plate 19 during the pressing process, enabling operators to easily open or close the hydraulic rod 22 to control the displacement of the shock absorber spring 16.
[0034] Before pressing the shock absorber spring 16, the rotating block 5 is rotated counterclockwise via the set rotating block 5. Then, the lead screw 6 starts to rotate counterclockwise. The rotation of the lead screw 6 causes the slider 7 and the fixed rod 11 to move closer to the support block 4. Then, the two moving blocks 13 and the two fixed blocks 8 move away from the slider 7. Subsequently, the two connecting rods 14, the two clamping plates 18, and the two limiting plates 19 move away from the shock absorber telescopic rod 17. At this time, the shock absorber spring 16 and the shock absorber telescopic rod 17 are placed on top of the support base 1. When the pressing plate 21 begins to pre-compress the shock absorber spring 16, the support block 4 is rotated clockwise. Then, the lead screw 6 starts to rotate clockwise. Rotation causes slider 7 and fixed rod 11 to move away from support block 4. Subsequently, two moving blocks 13 and two fixed blocks 8 move closer to slider 7, driving two connecting rods 14, two clamping plates 18 and two limiting plates 19 to move closer to shock absorber telescopic rod 17. When the two clamping plates 18 are in close contact, rotation of rotating block 5 stops. At this time, the two clamping plates 18 and the two limiting plates 19 are in close contact, completing the limiting of the spring. This allows the operator to read the scale of the limiting plate 19 at this time, so that the operator can keep track of the displacement of the limiting plate 19 during the subsequent pressing of the shock absorber spring 16 by the pressing plate 21, and thus determine the degree of compression of the shock absorber spring 16.
[0035] Before pressing the shock absorber spring 16, the positioning rods 3 are pulled to move them away from the clamping plate 18. At this time, the locking block 28 is subjected to a force close to the positioning rods 3, causing it to move closer to the limiting hole 26. Subsequently, the second spring 27 moves closer to the limiting hole 26. Meanwhile, the moving plate 29 slides away from the clamping plate 18 inside the slide groove 2. When the positioning rods 3 reach the end of the slide groove 2, the pulling of the positioning rods 3 stops. Then, the force generated by the deformation of the limiting hole 26 causes the locking block 28 to move closer to the fixing hole 25, thus limiting the positioning rods 3. This allows the shock absorber spring 16 and the shock absorber telescopic rod 17 to be placed on top of the support base 1. After the shock absorber telescopic rod 17 is placed on top of the support base 1, push the positioning rod 3 to move the two positioning rods 3 towards the clamping plate 18. At this time, the locking block 28 is subjected to the force of the positioning rod 3, and then the locking block 28 moves towards the limiting hole 26. Subsequently, the second spring 27 moves towards the limiting hole 26. At this time, the moving plate 29 slides inside the slide groove 2 towards the clamping plate 18. When the positioning rod 3 moves to the top of the slide groove 2, stop pulling the positioning rod 3. Then the force generated by the deformation of the limiting hole 26 causes the locking block 28 to move towards the fixing hole 25, thereby completing the limiting of the positioning rod 3. This allows the position of the pressing plate 21 to be adjusted by moving the positioning rod 3, so that the pressing plate 21 can press the shock absorber spring 16.
