[0002] With the development of modern industrial technology, the working conditions of mechanical equipment are becoming increasingly demanding, placing higher requirements on their reliability and durability. Therefore, mechanical vibration tests, which simulate actual working conditions to test the performance of mechanical equipment during the research and development stage, are becoming increasingly important. The support device of the vibration table is an important component of the entire vibration table, and it is generally equipped with a damping device to prevent the overall displacement of the vibration table during operation.

[0003] Existing vibration table support devices cannot adjust the damping amplitude of the device according to the actual needs of the object being tested, and most of them are unidirectional clamping, which leads to unstable clamping. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing moving platform support device cannot adjust the shock absorption amplitude of the device according to the actual needs of the object being measured, and the one-way clamping method will lead to unstable clamping.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

A motor base is fixed to the side wall of the vibration table body. A motor is fixed to the motor base. The output end of the motor is fixed to the double-threaded screw. A clamping plate is fixed to the top of the slider.

[0009] Preferably, a silicone protective layer is fixed to the clamping plate.

[0010] Preferably, the groove and the slider are adapted to each other in shape and have a trapezoidal cross-section.

[0011] Preferably, the base is made of high-strength cast iron with a thickness of not less than 50 mm.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-2 As shown, a support device for a vibration table includes a base 1 and a vibration table body 2. Limiting posts 3 are fixedly connected to the four corners of the base 1. Springs 4 are sleeved on the limiting posts 3. Buffer washers 5 are provided at the bottom of the limiting posts 3. The buffer washers 5 are fixedly connected to the bottom of the springs 4. An adjustment assembly 6 is fixedly connected to the top of the springs 4. The vibration table body 2 is mounted on the adjustment assembly 6. A clamping assembly 7 is provided on the vibration table body 2. The base 2 is made of high-strength cast iron with a thickness of not less than 50mm, providing good load-bearing and support functions. The springs 4 are standard compression springs made of spring steel wire with an elastic coefficient of K = 1.5N / mm to 2N / mm, providing good elasticity.

[0024] like Figure 1-3 As shown, the adjustment component 6 includes a sleeve 8 that passes through the vibration table body 2. A limiting ring 9 is fixed to the top of the sleeve 8. A mounting frame 10 is fixed to the top of the vibration table body 2. The mounting frame 10 is located directly above the sleeve 8. A screw 11 is fixed to the top of the mounting frame 10 and extends downward. The screw 11 extends into the sleeve 8. A nut 12 is threaded onto the screw 11 and is located above the limiting ring 9. The nut 12 and the screw 11 are made of stainless steel. The buffer washer 5 is made of polyurethane and plays an auxiliary role in sound absorption and noise reduction.

[0025] like Figure 1-2 As shown in Figures 4-5, the clamping assembly 7 includes a slide groove 13, which is located in the middle of the vibration table body 2. A slider 14 symmetrically arranged in the slide groove 13 is slidably arranged in the slide groove 13. A double-threaded screw 15 is provided in the slide groove 13. The double-threaded screw 15 is threaded through the slider 14 and its end is rotatably connected to the end of the slide groove 13 through a bearing. A motor base 16 is fixed to the side wall of the vibration table body 2. A motor 17 is fixed to the motor base 16. The output end of the motor 17 is fixed to the double-threaded screw 15. A clamping plate 18 is fixed to the top of the slider 14. A silicone protective layer 19 is fixed to the clamping plate 18. The slide groove 13 and the slider 14 are adapted to each other and have a trapezoidal cross section to limit the movement.

[0026] In practical use, when adjusting the damping amplitude, the operator first presses one corner of the vibration table body 2 to deform the spring 4. Then, the operator uses a wrench to turn the nut 12 downwards along the screw 11 until it stops rotating at the appropriate position. At this time, the nut 12 presses down on the limiting ring 9, the limiting ring 9 presses down on the sleeve 8, and the sleeve 8 presses down on the spring 4. The damping amplitude of the spring 4 is adjusted as the nut 12 moves downwards. When double-sided clamping of the test object is required, the test object is first placed between the two sets of clamping plates 18. Then, the motor 17 is started. The motor 17 drives the double-threaded screw 15 to rotate, generating force that drives the two sets of sliders 14 to move towards each other, so that the clamping plates 18 clamp the test object in both directions. In summary, this device can change the preload of the spring 4 by rotating the nut 12, thereby controlling the overall stiffness of the support device. This can maintain a stable support state under different loads and also allows users to flexibly adjust the height of the equipment according to specific needs. By setting the clamping component 7, bidirectional clamping of the test object can be achieved, making the clamping more stable.
