[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figure 1 - Figure 4, An embodiment provided by the present utility model: An automatic fixture quick replacement device for a shock absorber fatigue testing machine, including a machine body 1, a first fixing plate 2 is fixedly connected to the bottom of the machine body 1, a connecting plate 3 is slidably connected inside the first fixing plate 2, a second fixing plate 4 is fixedly connected to the bottom of the connecting plate 3, a second fixing plate 4 is fixedly connected to the front side of the connecting plate 3, a telescopic rod 5 is fixedly connected to the front side of the second fixing plate 4, a moving plate 6 is fixedly connected to the telescopic end of the telescopic rod 5, limiting blocks 7 are fixedly connected to both the left and right sides of the moving plate 6, a connecting block 8 is slidably connected to the outer periphery of the limiting block 7, and a fixing rod 9 is fixedly connected to one side of the connecting block 8. The machine body 1 is used to fix the first fixing plate 2. The first fixing plate 2 is installed at the bottom of the machine body 1. By being connected to the connecting plate 3, it ensures the stability of the connecting plate 3 and provides a basic supporting function at the same time. The connecting plate 3 is used to connect the first fixing plate 2 and the second fixing plate 4, and undertakes the function of sliding adjustment, enabling the second fixing plate 4 to move smoothly on it and adjusting the position of the fixture. The second fixing plate 4 is the installation platform of the clamping assembly, and is internally provided with a plurality of chutes to accommodate the sliding plate 13 and allow it to slide along the chutes to adjust the clamping position. The telescopic rod 5 is used to push the moving plate 6 to move back and forth, and adjusts the overall position of the fixture through the telescopic action to achieve the automatic adjustment function. The moving plate 6 is driven by the telescopic rod 5 and is responsible for adjusting the front and back positions of the fixture in the device to ensure that the fixture can adapt to shock absorbers of different sizes. The limiting blocks 7 are installed on both sides of the moving plate 6 to limit the moving range of the moving plate 6 and ensure that the moving plate 6 remains within a predetermined track during operation. The connecting block 8 is used to connect the limiting block 7 and the fixing rod 9, allowing the fixture to be adjusted and fixed within a certain range. The fixing rod 9 is inserted into the chute of the first fixing plate 2 to support the fixture and limit its movement range, ensuring the stability and precise positioning of the fixture.

[0035] Refer to Figure 1 , Figure 5 and Figure 6, a clamping component is arranged inside the second fixing plate 4. The clamping component is used to fix the shock absorber. The clamping component includes a motor 10. The motor 10 is fixedly connected inside the second fixing plate 4. The driving end of the motor 10 is fixedly connected with a rotating block 11. A plurality of uniformly distributed rotating plates 12 are rotatably connected to the bottom of the rotating block 11. One end of the rotating plate 12 away from the rotating block 11 is rotatably connected with a sliding plate 13. A clamping plate 14 is fixedly connected to the bottom of the sliding plate 13. The motor 10 is used to drive the rotating block 11 to rotate, providing a power source, controlling the opening and closing of the clamping component through the rotating action, and realizing the automatic clamping and loosening operations. The rotating block 11 is driven by the motor 10 to drive a plurality of rotating plates 12 to rotate uniformly, cooperatively controlling the movement of the sliding plate 13, so as to realize the opening and closing actions of the fixture. The rotating plate 12 is used to connect the rotating block 11 and the sliding plate 13, driving the sliding plate 13 to move through the rotation of the rotating block 11, and realizing the closing or separating operation of the clamping plate 14. The sliding plate 13 is connected in the chute of the second fixing plate 4. As one of the movable parts of the fixture, the clamping plate 14 is connected to the bottom. The movement of the fixture is realized with the action of the rotating plate 12. The clamping plate 14 is in direct contact with the shock absorber, and the clamping or loosening operation is carried out through the rotating mechanism driven by the motor 10 to ensure the stability of the shock absorber during the test.

[0036] Refer to Figure 2 , Figure 4 and Figure 5 , a plurality of uniformly distributed chutes are opened inside the second fixing plate 4. The outer periphery of the sliding plate 13 is slidably connected in the chute inside the second fixing plate 4. An anti-slip pad 15 is fixedly connected to one side of the clamping plate 14. The material of the anti-slip pad 15 is rubber. Chutes are opened on both the left and right sides inside the first fixing plate 2. One end of the fixing rod 9 away from the connecting block 8 is slidably connected in the chute inside the first fixing plate 2. A slider 16 is fixedly connected to the bottom of the connecting block 8. The outer periphery of the slider 16 is slidably connected inside the connecting plate 3. The telescopic end of the telescopic rod 5 is slidably connected inside the connecting plate 3. The top of the clamping plate 14 is slidably connected to the bottom of the second fixing plate 4. The anti-slip pad 15 is installed on the surface of the clamping plate 14 and is made of rubber material to increase the friction force, prevent the shock absorber from sliding when being clamped, and ensure the stability of the clamping. The slider 16 is fixed to the bottom of the connecting block 8 and is slidably connected to the connecting plate 3, providing smooth sliding support so that the connecting block 8 can move on the connecting plate 3.

[0037] Working principle: By starting the telescopic rod 5, the telescopic end of the telescopic rod 5 pushes the moving plate 6 to move. The moving plate 6 drives the two limit blocks 7 to move accordingly. The movement of the limit blocks 7 drives the connecting block 8 to move synchronously, and through the connecting block 8, drives the fixed rod 9 to slide in the chute inside the first fixing plate 2. The fixed rod 9 gradually disengages from the chute, thus releasing the fixation of the connecting plate 3. The second fixing plate 4 and the clamping component thereon will also be released from the fixation with the machine body 1. At this time, the second fixing plate 4 can be quickly disassembled, thereby realizing the quick replacement of the fixture. After the fixture is installed and fixed, the device enters the clamping operation stage of the shock absorber. At this time, by starting the motor 10, the motor 10 drives the rotating block 11 to rotate, so that the rotating block 11 drives a plurality of rotating plates 12 to rotate. The rotation of the rotating plates 12 can drive the sliding plate 13 to move in the chute inside the second fixing plate 4 along a specific direction. When the sliding plate 13 moves, it can drive the clamping plate 14 to clamp. The clamping plate 14 tightly clamps the shock absorber through the closing action to prevent it from sliding or shifting during the test.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
