Description

Technical Field

[0001] This utility model relates to the field of vibration reduction, and in particular to a stable hollow rotary assembly device with an adaptive vibration reduction structure. Background Technology

[0002] Hollow rotary assembly devices typically refer to a type of mechanical structure with a hollow center that can bear loads and achieve rotational motion. Its core function is to provide rotational support. It is often used in scenarios where pipelines, cables, gases, or liquids need to pass through during rotation, such as industrial robots, machine tools, and automated equipment.

[0003] Traditional hollow rotary assembly devices have poor vibration damping. When the device is subjected to external vibration or impact, there is a lack of effective vibration damping structure to absorb and dissipate vibration energy. The vibration will be directly transmitted to the key components of the device, such as the hollow rotary platform, which will not only affect the normal operation of these components, but may also shorten their service life. Utility Model Content

[0004] To overcome the shortcomings of lacking a damping structure, this utility model provides a stable hollow rotary assembly device with an adaptive damping structure.

[0005] The technical solution is as follows: A stable hollow rotary assembly device with an adaptive damping structure, comprising a lower support base plate, support rods, telescopic rods, elastic elements, an upper support plate, an upper support frame, a lower support frame, damping springs, and a hollow rotary platform. Multiple support rods are rotatably mounted on the upper side of the lower support base plate, and telescopic rods are slidably mounted on the support rods. Elastic elements connect the support rods and telescopic rods, and the telescopic rods are rotatably connected to the upper support plate. A hollow rotary platform is mounted on the upper side of the upper support plate, and multiple upper support frames are mounted on the lower side of the upper support plate. Multiple lower support frames are mounted on the upper side of the lower support base plate, with each upper and lower support frame corresponding to the previous one. Damping springs are provided between the corresponding upper and lower support frames.

[0006] Furthermore, it also includes a limiting inclined plate and an anti-detachment plate. The lower side of the upper support frame is provided with a limiting inclined plate, and the upper side of the lower support frame is provided with an anti-detachment plate. Both the limiting inclined plate and the anti-detachment plate are arc-shaped, and a shock-absorbing spring is connected between the limiting inclined plate and the anti-detachment plate.

[0007] Furthermore, the upper support plate has an installation port on its upper side and multiple fixing holes on its upper side. The installation port and fixing holes are used to install the hollow rotating platform.

[0008] Furthermore, the shock-absorbing spring is placed horizontally.

[0009] Furthermore, there are four support rods and four telescopic rods, which are located at the four corners of the lower support base plate.

[0010] Furthermore, the upper support frame or the lower support frame is located at the edge of the upper support plate or the lower support base plate.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model achieves a certain degree of adaptive adjustment through the design of support rods, telescopic rods and elastic elements, and through the elastic deformation of the elastic elements, in order to adapt to different working conditions and load changes. The design of upper support frame, lower support frame and shock-absorbing spring further improves the shock absorption effect.

[0012] 2. This utility model, through the arc-shaped design of the limiting inclined plate and the anti-detachment plate, can guide the displacement direction of the shock-absorbing spring during compression or tension, thereby improving the shock absorption effect. At the same time, the arc-shaped contact surface can evenly distribute the force on the shock-absorbing spring, reduce local stress concentration, and extend the service life of the spring.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] A stable hollow rotary assembly device with an adaptive damping structure, such as Figures 1-4As shown, it includes a lower support base plate 1, support rods 2, telescopic rods 3, elastic elements 4, an upper support plate 5, an upper support frame 6, a lower support frame 7, shock-absorbing springs 8, and a hollow rotating platform 9. Multiple support rods 2 are rotatably mounted on the upper side of the lower support base plate 1. Telescopic rods 3 are slidably mounted on the support rods 2. Elastic elements 4 connect the support rods 2 and the telescopic rods 3, and the elastic elements 4 surround the outside of the telescopic rods 3. The telescopic rods 3 are rotatably connected to the upper support plate 5. A hollow rotating platform 9 is installed in the middle of the upper side of the upper support plate 5. Multiple upper support frames 6 are located on the lower side of the upper support plate 5, and multiple lower support frames 7 are located on the upper side of the lower support base plate 1. The upper support frames 6 and lower support frames 7 correspond one-to-one, and shock-absorbing springs 8 are provided between the corresponding upper support frames 6 and lower support frames 7.

[0020] When the upper support plate 5 is subjected to external force, it can achieve a certain degree of adaptive adjustment through the sliding of the telescopic rod 3 on the support rod 2 and the elastic deformation of the elastic element 4, so as to adapt to different working conditions and load changes. When the device is subjected to external vibration or impact, the upper support plate 5 will produce a small vertical or horizontal displacement. At this time, the relative position between the upper support frame 6 and the lower support frame 7 changes, and the shock-absorbing spring 8 is compressed or stretched, using its elastic characteristics to absorb and consume vibration energy, thereby playing a role in shock absorption.

[0021] like Figure 1 and Figure 3 As shown, it also includes a limiting inclined plate 61 and an anti-detachment plate 71. The upper support frame 6 has a limiting inclined plate 61 on its lower side, and the lower support frame 7 has an anti-detachment plate 71 on its upper side. Both the limiting inclined plate 61 and the anti-detachment plate 71 are arc-shaped. The shock-absorbing spring 8 is connected between the limiting inclined plate 61 and the anti-detachment plate 71. The arc-shaped design of the limiting inclined plate 61 and the anti-detachment plate 71 can guide the displacement direction of the shock-absorbing spring 8 during compression or tension, thereby improving the shock absorption effect. At the same time, the arc-shaped contact surface can evenly distribute the force on the shock-absorbing spring 8, reduce local stress concentration, and extend the service life of the spring.

[0022] The upper support plate 5 has an installation port 51 on its upper side and multiple fixing holes 52 on its upper side. The installation port 51 and fixing holes 52 are used to install the hollow rotating platform 9. The installation port 51 can provide the hollow rotating platform 9 with preliminary positioning and installation space so that it can be accurately placed in a suitable position. The fixing holes 52 facilitate the use of bolts and other fasteners to firmly fix the hollow rotating platform 9 to the upper support plate 5.

[0023] The shock-absorbing spring 8 is placed horizontally, which can reduce the horizontal displacement between the upper support plate 5 and the lower support base plate 1.

[0024] There are four support rods 2 and four telescopic rods 3. The four support rods 2 are located at the four corners of the lower support plate 1 to ensure that the load of the upper support plate 5 is evenly distributed to each support point and to avoid local overload that could cause structural deformation.

[0025] The upper support frame 6 or the lower support frame 7 are located at the edge of the upper support plate 5 or the lower support base plate 1, so that the shock-absorbing springs 8 are distributed on the periphery of the structure. When subjected to impact, the edge support can more effectively disperse the vibration energy, improve the stability of the overall device, and at the same time avoid interference between the support frame and the components (such as motors and transmission mechanisms) of the hollow rotating platform 9.

[0026] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
