Description

Technical Field

[0001] This invention relates to the field of optical platform technology, specifically to a vibration isolation optical platform. Background Technology

[0002] Optical platforms, also known as optical breadboards, optical desktops, scientific desktops, or experimental platforms, provide a horizontal and stable surface. Generally, platforms require vibration isolation and other measures to ensure they are not disturbed by external factors and that scientific experiments can proceed normally. They are divided into two main categories: active and passive. Passive platforms are further divided into rubber and air flotation types.

[0003] The optical platform strives for horizontality. First, the entire table surface is extremely flat during processing. Then, the table surface is placed on four interconnected airbags to ensure that the table surface is horizontal. The table surface is covered with engineering threaded holes arranged in a square. Optical components can be fixed with these holes and corresponding screws. In this way, when you complete the construction of the optical equipment, the system will not be affected by external disturbances. Even if the table surface is pressed, it will automatically return to horizontality due to the airbags.

[0004] Existing optical platforms can achieve stability of optical devices placed on the platform surface through vibration isolation structures. However, since the weight of the optical devices placed on the optical platform surface is variable, the vibration isolation effect of the optical platform will be greatly reduced if the weight of the optical devices is too heavy. Therefore, we propose a vibration-isolated optical platform. Summary of the Invention

[0071] The load-bearing damping device 3 is installed at the bottom of the optical platform body 1 and provides vertical toughness support for the optical platform body 1. The load-bearing damping device 3 includes: a load-bearing and guiding component 31, a load-bearing arc plate 311, a limiting groove 312, a toughness component 32, a support rod 321, a sliding plate 322, a tension damping component 33, a bidirectional damper 331, and a tension spring 332. The load-bearing and guiding component 31 is installed on the surface of the load-bearing plate 14 and limits and guides the movement of the toughness component 32. The load-bearing arc plate 311 is installed on the surface of the load-bearing plate 14. The limiting groove 312 is located on the top of the load-bearing arc plate 311 and limits and guides the movement of the toughness component 32. The top of the toughness component 32 is connected to the bottom of the platform 13, and the bottom is slidably connected to the load-bearing and guiding component 311. Inside the support rod 1, through the cooperation of the toughness component 32 and the load-bearing and guiding component 31, the placement platform 13 can be toughly supported.

[0072] In practical use, those skilled in the art will understand that when using the optical platform body 1, by placing the optical equipment on the placement platform 13 of the optical platform body 1, the support rod 321 is first subjected to force and then moves downwards, causing the slide plate 322 to slide inside the limiting groove 312 of the load-bearing arc plate 311. When the support rod 321 expands to both sides, the bidirectional damper 331 cooperates with the tension spring 332 to dampen the vibration of the two sets of support rods 321, thereby increasing the vertical stability of the placement platform 13. With the placement platform 13 bearing the weight, the first vertical damper 211 and the second vertical damper 213 generate damping, and at the same time, the flexible arc plate 221 undergoes arc deformation, sliding... Shaft 224 slides on the outer wall of side rod 214. At this time, under the pull of the first spring 225 and the second spring 232, and under the damping action of the first damper 223, vibration is isolated in the vertical vibration direction of the placement platform 13, and the placement platform 13 quickly returns to the initial position, thereby increasing the vertical vibration isolation capability of the placement platform 13. When vibration occurs on the side of the placement platform 13, the side arc plate 231 slides, and under the action of the second spring 232 and the third spring 233, it first isolates vibration, and then quickly returns to the initial position under the action of the side damper 234, thereby isolating the side of the placement platform 13 and increasing the damping capability of the side of the placement platform 13.

In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
