Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a vibration test bench fixing bracket, and more specifically, to a vibration test bench fixing bracket. Background Art
[0002] In the prior art, the design of the fixed bracket of the vibration test bench has some limitations, especially in terms of position fine-tuning and rigid connection adjustment. The vibration test bench is used to simulate vibration conditions in various environments to test and evaluate the vibration resistance of components and systems. However, the existing fixed brackets are usually designed in a relatively fixed and non-adjustable manner, which means that once the installation is determined, it is difficult for the user to make fine adjustments to the specific position of the test bench. This design not only limits the flexibility of the test, but also may make it impossible to optimize the configuration under specific test configurations or space constraints.
[0003] In addition, the non-adjustability of rigid connections is another major issue. In some test applications, it may be necessary to adjust the rigidity of the connection to change the response characteristics of the test bench according to the size of the test load or the specific needs during the test. For example, a flexible connection may be more suitable for high-frequency vibration testing, while a rigid connection may be more suitable for low-frequency or high-amplitude vibration. Existing fixed brackets that cannot adjust the rigidity of the connection will not be able to adapt to these different test requirements, which may lead to inaccurate test results or fail to fully simulate actual application conditions.

The moving mechanism is cooperatively connected to the base 1 and the adjusting plate 2. A plurality of springs 3 are arranged, and the two ends of each spring 3 are respectively connected to the bottom ring 4 and the top ring 5. The bottom ring 4 is mounted on the adjusting plate 2. The adjusting ring 6 is coaxially mounted on the spring 3. An angle plate 7 is respectively mounted on both sides of the adjusting ring 6. A transverse plate 8 is fitted between the two angle plates 7. The fixing bolt 9 is connected to the transverse plate 8 and the angle plate 7. The fixing mechanism is mounted on the spring 3. The fixing mechanism comprises a receiving plate 10 and an adjusting bolt 11. The receiving plate 10 is fitted on a plurality of top rings 5.

A threaded hole 12 is respectively opened in each adjusting ring 6, and the adjusting bolt 11 is threadedly connected in the threaded hole 12.
[0030] In this embodiment, before conducting the vibration test, the length of the adjusting bolt 11 is first selected according to the situation, and then the corresponding adjusting bolt 11 is threadedly connected in the corresponding number of adjusting rings 6. The connected part is in a fixed state, so the stiffness coefficient of the spring 3 can be adjusted to change the vibration situation. Then, multiple transverse plates 8 are respectively connected to the angle plates 7 on both sides, and then fixed by fixing bolts 9. Therefore, the synchronization of multiple springs 3 can be guaranteed, thereby improving the use effect.
[0031] See also Figures 3 to 5 As an implementation of the moving mechanism: the moving mechanism includes an intermediate plate 13 and a sliding block 14, the intermediate plate 13 is fitted between the adjusting plate 2 and the base 1, the sliding blocks 14 are respectively installed on the base 1 and the intermediate plate 13, the side walls of the adjusting plate 2 and the intermediate plate 13 are respectively provided with lateral grooves 15, the sliding block 14 is slidably connected in the lateral grooves 15, the base 1 and the intermediate plate 13 are respectively provided with limit blocks 16, the limit block 16 is provided with a slot 17, a follower rod 18 is slidably provided in the slot 17, a lead screw 19 is coaxially provided on the follower rod 18, insertion holes 20 are respectively provided on the intermediate plate 13 and the adjusting plate 2, an insertion block 21 is slidably provided in each insertion hole 20, the lead screw 19 is threadedly connected in the insertion block 21, and a handle 22 is coaxially provided on the follower rod 18.
[0032] More specifically, when the overall position needs to be adjusted, the handle 22 is first turned to drive the follower rod 18 to rotate.

The connected part is in a fixed state, so the stiffness coefficient of the spring 3 can be adjusted to change the vibration situation, and then multiple transverse plates 8 are respectively connected to the angle plates 7 on both sides, and then fixed by fixing bolts 9, so that the synchronization of multiple springs 3 can be guaranteed, thereby improving the use effect.
[0034] When the overall position needs to be adjusted, first, the handle 22 can be turned to drive the follower rod 18 to rotate. Since the follower rod 18 is stuck in the slot 17, the limit between the follower rod 18 and the limit block 16 is guaranteed, and the rotation is also guaranteed. Then the screw 19 will rotate synchronously with the follower rod 18, and the screw 19 is threadedly connected to the insertion block 21, and the insertion block 21 is stuck in the insertion hole 20, so it will drive the movement of the adjustment plate 2 and the intermediate plate 13.
