Description
Technical Field
[0001] This utility model relates to the field of vibration table installation technology, and in particular to a vibration table installation and fixing component. Background Technology
[0002] A vibration table is a testing device used to simulate mechanical vibration environments. It is widely used in product quality inspection, material performance analysis, and reliability testing. It applies mechanical loads of specific frequencies and amplitudes to the test object through controlled vibration excitation to evaluate its dynamic response characteristics and structural durability.1 Its core function is to accurately reproduce the vibration spectrum under real working conditions, providing a standardized mechanical environment simulation platform for industrial R&D and experimental research.1
[0003] In existing vibration table mounting and fixing technologies, although traditional rigid connection methods can ensure structural stability, they lack an effective attenuation mechanism for high-frequency vibrations. This causes vibration energy to be directly transmitted to surrounding equipment through the base, resulting in resonance interference and affecting the accuracy of test data. Especially when dynamic adjustment of the test posture is required, it is difficult to achieve coordinated optimization of vibration reduction and posture control. Therefore, a vibration table mounting and fixing component is provided to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to solve the problem of difficulty in achieving coordinated optimization of vibration reduction and posture control in the prior art, and to propose a vibration table mounting and fixing component.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A vibration table mounting and fixing assembly includes a fixed base, on which multiple support components are mounted. A movable base is slidably connected to the top of the fixed base. A vibration table position adjusting component is mounted on the movable base to assist in adjusting the position of the movable base. The vibration table position adjusting component is connected to the multiple support components.
[0007] The top of the movable base is equipped with a vibration table body.
[0008] Preferably, the fixed base includes a base body, an electric contact plate is installed on the top of the base body, the electric contact plate is attached to the bottom of the movable base, and a control console for receiving signals from the electric contact plate is also installed on the base body.
[0009] Preferably, the vibration table position adjustment component includes two first screws and a second screw arranged horizontally and vertically. The second screw is located above the first screw. One end of the first screw and the second screw is connected to a servo motor via a coupling. The other end of the first screw and the second screw is rotatably connected to a support block. The two support blocks and the two servo motors are all connected to the adjacent support components.
[0010] Preferably, the vibration table body includes a table surface, and spring supports are installed at the four corners of the bottom of the table surface. The bottom ends of the four spring supports are connected to a movable base, and a vibration motor is installed at the bottom of the table surface.
[0011] Preferably, the support assembly includes a base, with side plates installed on both sides of the top of the base, a rubber buffer pad slidably connected to the base, and a buffer spring installed at the bottom of the base. The base is slidably connected to the fixed base through the buffer spring.
[0012] Preferably, each of the two side plates is connected to a buffer spring on an adjacent side, and each of the two buffer springs is connected to a washer.
[0013] Preferably, the movable base includes a base frame, on which a transverse screw cylinder is mounted, and the base frame and the transverse screw cylinder are threadedly connected to the first screw and the second screw, respectively.
[0014] Preferably, the base frame is equipped with feet at all four corners, and the bottom of each of the four feet is rotatably connected to a metal roller.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. The vibration table mounting and fixing assembly achieves high-precision multi-dimensional position control through the integration of an electric contact plate positioning system and a dual-axis servo adjustment mechanism. The moving base can track the position coordinates in real time under the feedback of the electric contact plate signal and the displacement can be precisely adjusted through the control console. At the same time, the cross screw transmission system drives the stable sliding in the lateral and longitudinal directions. Combined with the composite support structure of spring support feet and metal rollers, it not only ensures the structural rigidity of the vibration table body during dynamic adjustment, but also greatly improves the repeatability of the test posture through electrified positioning.
[0017] 2. The vibration table mounting and fixing components significantly optimize the vibration transmission path through a modular buffer system. The synergistic effect of the rubber buffer pad and multi-directional buffer spring in the support components effectively absorbs high-frequency vibration energy. The flexible side support structure, together with the sliding base, converts mechanical vibration into controllable elastic deformation. At the same time, the contact sensing mechanism of the electric contact plate and the metal roller can synchronously record the movement trajectory, forming a dual function of vibration reduction and noise reduction as well as motion monitoring. While ensuring the reliability of experimental data, it minimizes the interference of vibration on surrounding equipment and the environment. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] like Figure 1-5 As shown, this utility model provides a vibration table mounting and fixing assembly, including a fixed base 1, a plurality of support components 4 mounted on the fixed base 1, a movable base 5 slidably connected to the top of the fixed base 1, a vibration table position adjusting component 2 for assisting the movable base 5 in adjusting its position, and the vibration table position adjusting component 2 being connected to the plurality of support components 4.
[0027] The vibration table body 3 is mounted on the top of the movable base 5.
[0028] In this embodiment, the fixed base 1 includes a base body 11, an electric contact plate 12 is installed on the top of the base body 11, the electric contact plate 12 is attached to the bottom of the movable base 5, and a control console 13 for receiving signals from the electric contact plate 12 is also installed on the base body 11.
[0029] Inside the fixed base 1, an electric contact plate 12 is installed on the base body 11, which can cooperate with the movable base 5. When the bottom of the movable base 5 contacts the electric contact plate 12, the electric contact plate 12 is energized to generate current, which can identify the position of the movable base 5 and transmit it to the control console 13 through an electrical signal. At this time, the corresponding information can be seen on the control console 13. In this way, the movable base 5 can be moved more accurately by controlling the support component 4.
[0030] In this embodiment, the vibration table position adjustment component 2 includes two horizontally and vertically arranged first screws 23 and second screws 24. The second screw 24 is located above the first screw 23. One end of the first screw 23 and the second screw 24 is connected to a servo motor 21 through a coupling. The other end of the first screw 23 and the second screw 24 is rotatably connected to a support block 22. Both support blocks 22 and the two servo motors 21 are connected to the adjacent support component 4.
[0031] Within the vibration table position adjustment component 2, two sets of servo motors 21 and support blocks 22 cooperate with the first screw 23 and the second screw 24 respectively, forming a cross-shaped arrangement. When the servo motor 21 on the second screw 24 is started, the movable base 5, under its constraint, allows the movable base 5 to slide along the direction of the second screw 24. When the servo motor 21 on the first screw 23 rotates, the movable base 5 will move towards the first screw 23. This achieves position adjustment in the horizontal and vertical directions, and, in conjunction with the support component 4 and the fixed base 1, makes the overall movement more stable.
[0032] In this embodiment, the vibration table body 3 includes a table surface 31, and spring support legs 32 are installed at the four corners of the bottom of the table surface 31. The bottom ends of the four spring support legs 32 are connected to the movable base 5, and a vibration motor 33 is installed at the bottom of the table surface 31.
[0033] In this embodiment, the support component 4 includes a base 42, with side plates 41 installed on both sides of the top of the base 42. A rubber buffer pad 43 is slidably connected to the base 42, and a buffer spring 44 is installed at the bottom of the base 42. The base 42 is slidably connected to the fixed base 1 through the buffer spring 44. A buffer spring 44 is connected to one of the adjacent sides of the two side plates 41, and a pad 45 is connected to each of the two buffer springs 44.
[0034] Within the support assembly 4, the base 42 and the buffer spring 44 serve as the bottom support, while the rubber buffer pad 43 is connected to the servo motor 21 or the support block 22. At this time, the side plate 41, the buffer spring 44, and the pad 45 form a lateral flexible support. When the vibration table body 3 vibrates, the servo motor 21 can sway laterally through the sliding of the rubber buffer pad 43 and the base 42. In this way, the rubber buffer pad 43 can work with the buffer spring 44 and the pad 45 to buffer the vibration and reduce the impact of the vibration on the surrounding environment.
[0035] In this embodiment, the movable base 5 includes a base frame 51, on which a transverse screw cylinder 52 is mounted. The base frame 51 and the transverse screw cylinder 52 are threadedly connected to the first screw 23 and the second screw 24, respectively. Foot 53 is mounted at each of the four corners of the bottom of the base frame 51, and metal rollers 54 are rotatably connected to the bottom of each of the four foot 53.
[0036] When the electric contact plate 12 contacts the metal roller 54, it transmits a signal to the control console 13, which will then display four points on the control console 13. When the metal roller 54 moves, the four points on the control console 13 will also move accordingly. The control console 13 can use a grid and coordinate system to identify the position and distance of the movement. By controlling the servo motor 21, the overall operation effect can be achieved.
[0037] How to use and how to work this device:
[0038] When in use, the device is supported by a fixed base 1. The fixed base 1 is equipped with a vibration table position adjustment component 2, a support component 4, and a movable base 5. These components work together to fix the vibration table body 3 while adjusting the position of the movable base 5 as needed. The fixed base 1 and the support component 4 can also reduce the impact of the vibration of the vibration table body 3 on the surrounding environment.
[0039] Inside the fixed base 1, an electric contact plate 12 is installed on the base body 11, which can cooperate with the movable base 5. When the bottom of the movable base 5 contacts the electric contact plate 12, the electric contact plate 12 is energized to generate current, which can identify the position of the movable base 5 and transmit it to the control console 13 through an electrical signal. At this time, the corresponding information can be seen on the control console 13. In this way, the movable base 5 can be moved more accurately by controlling the support component 4.
[0040] Inside the vibration table position adjustment component 2, two sets of servo motors 21 and support blocks 22 cooperate with the first screw 23 and the second screw 24 respectively, forming a cross-shaped arrangement. When the servo motor 21 on the second screw 24 is started, the movable base 5 can slide along the direction of the second screw 24 under the constraint of the movable base 5. When the servo motor 21 on the first screw 23 rotates, the movable base 5 will move towards the first screw 23. This achieves the position adjustment in the horizontal and vertical directions. In addition, the support component 4 and the fixed base 1 can make the overall movement more stable.
[0041] Inside the vibration table body 3, the table surface 31 serves as the main support, and together with the spring support legs 32, it can form a stable connection between the vibration table body 3 and the movable base 5, and together with the vibration motor 33, it serves as the vibration body.
[0042] Inside the support assembly 4, the base 42 and the buffer spring 44 serve as the bottom support, while the rubber buffer pad 43 is connected to the servo motor 21 or the support block 22. At this time, the side plate 41, the buffer spring 44, and the pad 45 form a lateral flexible support. When the vibration table body 3 vibrates, the servo motor 21 can sway laterally through the sliding of the rubber buffer pad 43 and the base 42. In this way, the rubber buffer pad 43 can work with the buffer spring 44 and the pad 45 to buffer the vibration and reduce the impact of the vibration on the surrounding environment.
[0043] Inside the movable base 5, the base frame 51 and the transverse screw cylinder 52 cooperate with the first screw 23 and the second screw 24 to form the driving body. On this basis, the foot 53 cooperates with the metal roller 54 to support the sliding of the entire movable base 5 in any direction. Furthermore, the metal roller 54 cooperates with the electric contact plate 12 to leave movement information or movement trajectory on the electric contact plate 12.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
