Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle repair equipment technology, specifically to a shock absorber spring disassembly and assembly device for vehicle maintenance. Background Technology
[0002] In a vehicle's suspension system, shock absorber springs are a crucial component. Their primary function is to mitigate vibrations caused by uneven road surfaces during driving, ensuring both comfort and stability. Repairing or replacing shock absorber springs typically requires removing them from their mounting position. However, due to the high rigidity and elasticity of the shock absorber spring, direct removal without proper securing or compression poses a significant safety hazard, potentially causing the spring to eject and resulting in equipment damage or personal injury.
[0003] When using existing shock absorber spring removal and installation equipment to compress springs, there is a lack of specialized stabilizing structures to ensure that the spring does not accidentally detach from the compression tool. Because springs have a strong elastic restoring force, if they detach during compression, they will rebound uncontrollably, posing a threat to the personal safety of maintenance personnel and potentially damaging surrounding vehicle components. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a device for disassembling and assembling shock absorber springs for vehicle maintenance.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A shock absorber spring disassembly and assembly device for vehicle maintenance, used to compress the shock absorber spring body, includes a guide rod and two U-shaped blocks disposed on the side wall of the guide rod, the two U-shaped blocks being disposed opposite to each other;
[0007] Each of the above U-shaped blocks is slidably provided with several sliders via a limiting rail. The sliders are hollow structures with openings at the top, and curved blocks are installed at the top of the slider cavities.
[0008] A first arc-shaped block is provided above the aforementioned curved stop, and a pressure spring is provided at the bottom of the aforementioned first arc-shaped block. The bottom end of the pressure spring passes through the curved stop and is fixed to the bottom wall of the slider cavity.
[0009] The first arc-shaped block is rotatably connected to both sides of the first arc-shaped block. When the shock-absorbing spring body presses the first arc-shaped block to move toward the curved stop, the first arc-shaped block and the middle of the curved stop are in contact. The second arc-shaped block is squeezed and rotated by the curved stop, and after the second arc-shaped block rotates, it is located on both sides of the upper part of the shock-absorbing spring body.
[0010] Preferably, after the two second arc blocks are rotated, the arc range formed by the second arc block and the first arc block is 240 degrees to 300 degrees.
[0011] Preferably, the arc size of the first arc block is set to twice the arc size of the second arc block.
[0012] Preferably, the top of the slider is configured with two inwardly inclined slopes and a downwardly concave arc-shaped surface, with the two slopes symmetrically arranged about the arc-shaped surface.
[0013] Preferably, a limit block is provided at the bottom of the slider, and the slider is slidably connected to the limit rail via the limit block.
[0014] Preferably, a sleeve block is provided on the side of the U-shaped block near the guide rod, and the U-shaped block is sleeved on the guide rod via the sleeve block.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. When the shock absorber spring removal and installation equipment for vehicle maintenance is in use, after the shock absorber spring is stuck on the first arc-shaped block, it will press the first arc-shaped block to move towards the curved stop block. The second arc-shaped block rotates under the action of the curved stop block and is stuck on the side wall of the shock absorber spring, thus constraining the shock absorber spring in the arc-shaped structure formed by the first arc-shaped block and the second arc-shaped block, thereby improving the fixing effect of the shock absorber spring when the equipment compresses the shock absorber spring.
[0017] 2. When it is necessary to disassemble and assemble shock absorber springs of different sizes, when the U-shaped block brings the slider close to the shock absorber spring, the shock absorber spring can stick to the inclined surface of the slider and slide on the U-shaped block with the slider, so that the device can disassemble and assemble shock absorber springs of different sizes.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0029] Example
[0030] A device for disassembling and assembling shock absorber springs for vehicle maintenance, such as Figures 1-4 As shown, the shock-absorbing spring body 1 is compressed, including a guide rod 21 and two U-shaped blocks 23 disposed on the side wall of the guide rod 21. The two U-shaped blocks 23 are disposed opposite each other. A sleeve block 22 is disposed on the side of the U-shaped block 23 near the guide rod 21. The U-shaped block 23 is sleeved on the guide rod 21 through the sleeve block 22. A screw is disposed inside the guide rod 21. The lower sleeve block 22 is fixedly disposed, and the upper sleeve block 22 is threadedly connected to the screw. When it is necessary to compress the shock-absorbing spring body 1, the upper sleeve block 22 is moved downward by the screw, which can move the upper U-shaped block 23 downward, reducing the distance between the two U-shaped blocks 23, thereby compressing the shock-absorbing spring body 1.
[0031] In one embodiment, such as Figures 3-4 As shown, each U-shaped block 23 has several sliders 31 slidably arranged on the limiting rail 231. The cross section of the U-shaped block 23 is a concave structure. The limiting rail 231 is located at the bottom of the concave shape of the U-shaped block 23, and the sliders 31 are located inside the concave shape of the U-shaped block 23. At least three sets of limiting rail 231 and sliders 31 are provided to improve the effect of constraining the position of the shock-absorbing spring body 1 through the sliders 31.
[0032] In one embodiment, such as Figures 3-4As shown, the slider 31 is a hollow structure with an open top. A curved stop 32 is installed at the top of the slider 31 cavity. A first arc-shaped block 41 is set above the curved stop 32. A pressure spring 411 is set at the bottom of the first arc-shaped block 41. The pressure spring 411 is used to reset the first arc-shaped block 41. After the disassembly of the shock-absorbing spring body 1 is completed, the two U-shaped blocks 23 are separated, and the shock-absorbing spring body 1 is separated from the first arc-shaped block 41. When the shock-absorbing spring body 1 is separated from the first arc-shaped block 41, it will squeeze the two second arc-shaped blocks 42 to separate. The pressure spring 411 pushes the first arc-shaped block 41 to move away from the curved stop 32, so that the first arc-shaped block 41 is reset for the next use.
[0033] In one embodiment, such as Figures 3-4 As shown, the bottom end of the pressure spring 411 passes through the curved stop 32 and is fixed to the bottom wall of the cavity of the slider 31. The second curved block 42 is rotatably connected to both sides of the first arc block 41. When the damping spring body 1 presses the first arc block 41 to move towards the curved stop 32, the first arc block 41 is in contact with the middle of the curved stop 32. The second arc block 42 is squeezed and rotated by the curved stop 32, and after the second arc block 42 rotates, it is located on both sides of the upper part of the damping spring body 1.
[0034] The curved stop 32 has an arc-shaped structure in the middle, and the arc of the curved stop 32 is greater than that of the first arc block 41. The curved stop 32 can support the second arc block 42 on both sides. The curved design of the curved stop 32 allows the second arc block 42 to rotate around the first arc block 41 when the shock absorber spring body 1 presses the first arc block 41 against the middle of the curved stop 32. After rotation, the second arc block 42 cooperates with the first arc block 41 to lock the shock absorber spring body 1 inside the arc-shaped structure formed by the first arc block 41 and the second arc block 42, so that the shock absorber spring body 1 is locked in the slider 31, and thus the shock absorber spring body 1 is fixed on the U-shaped block 23.
[0035] In one embodiment, such as Figure 4 As shown, after the two second arc blocks 42 rotate, the arc range formed by the second arc block 42 and the first arc block 41 is 240 degrees to 330 degrees, so that the arc of the circular arc structure formed by the second arc block 42 and the first arc block 41 is greater than 180 degrees. After rotation, the distance between the rotating ends of the two second arc blocks 42 is less than the diameter of the shock-absorbing spring body 1, so that the second arc block 42 can limit the shock-absorbing spring body 1 and lock the shock-absorbing spring body 1 inside the circular arc structure formed by the first arc block 41 and the second arc block 42.
[0036] In one embodiment, such as Figure 4As shown, the arc size of the first arc block 41 is set to be twice the arc size of the second arc block 42. The top of the slider 31 is set with two inwardly inclined slopes and a downwardly concave arc surface. The two slopes are symmetrically arranged about the arc surface. The position of the first arc block 41 corresponds to the position of the arc surface of the slider 31, so that when the shock-absorbing spring body 1 presses the first arc block 41 and moves downward, the shock-absorbing spring body 1 is not only stuck inside the arc structure formed by the first arc block 41 and the second arc block 42, but can also abut against the arc surface of the slider 31.
[0037] In one embodiment, such as Figure 4 As shown, a limiting block 311 is provided at the bottom of the slider 31. The slider 31 is slidably connected to the limiting rail 231 via the limiting block 311. When the shock absorber spring disassembly and assembly device is applied to shock absorber spring bodies 1 of different diameters, the shock absorber spring disassembly and assembly device is brought close to the shock absorber spring body 1. The shock absorber spring body 1 is attached to the inclined surface of the slider 31, which drives the slider 31 to slide under the constraint of the upper limiting rail 231 of the U-shaped block 23. During the sliding process of the slider 31, the shock absorber spring body 1 gradually aligns with the arc surface of the slider 31, that is, gradually aligns with the first arc block 41. Then the shock absorber spring body 1 is inserted into the first arc block 41.
[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
