[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0029] Example 1

[0030] This embodiment discloses an optical vibration isolation platform, such as Figures 1 to 6 As shown, including:

[0031] Steel vibration isolation frame 1, three-way damping vibration isolation unit 2, X-axis elastic part 3, Y-axis elastic part 4, bottom surface 5, Z-axis elastic part 6, top surface 7, fixing screws 8, vibration isolation rubber 9, steel nut 10.

[0032] The steel vibration isolation bracket 1 and the bottom surface 5 on the four three-way damping vibration isolation units 2 are connected by screws. The bottom of the steel vibration isolation bracket is equipped with an adjustable foot cup with a vibration isolation pad, which can filter a small part of the vibration transmitted to the optical platform from the bottom surface. The height of the rack can be adjusted by rotating the adjustable foot cup to ensure that the entire vibration isolation rack is flat.

[0033] The X-axis elastic member 3 connects the bottom surface 5 and the top surface 7 through the fixing screw 8. The bottom surface 5 and the top surface 7 are elastically connected in the X direction. The X-axis elastic member 3 can attenuate the vibration of the bottom surface 5 in the X direction. The structure of the elastic member (including the X-axis elastic member 3, the Y-axis elastic member 4 and the Z-axis elastic member 6) is shown in FIG. Figure 3 As shown, the main structure is a vibration isolation rubber matched with a steel nut 10.

[0034] Similarly, the Y-axis elastic member 4 can attenuate the vibration of the bottom surface 5 in the Y direction; and the Z-axis elastic member 6 can attenuate the vibration of the bottom surface 5 in the Z direction.

[0035] In summary, in the utility model, the core structure of the optical vibration isolation platform that is distinguished from existing products lies in the three-way damping vibration isolation unit located on the frame, and the three-way damping vibration isolation unit includes: a Z-axial elastic member connected between the top surface and the bottom surface, the top surface is fixedly connected to the first side wall, and a contact-proof gap is left between the first side wall and the bottom surface; the bottom surface is fixedly connected to the second side wall, and a contact-proof gap is left between the second side wall and the top surface; an X-axial elastic member and a Y-axial elastic member that are perpendicular to each other are connected between the first side wall and the second side wall.

[0036] Preferably, the second side wall may be two right-angled vertical surfaces, the first side wall may be an arc surface, an optical breadboard is connected to the top surface, and the frame adopts a vibration isolation frame connected to the bottom surface. The vibration isolation frame is made of steel, and the X-axis elastic member, the Y-axis elastic member and the Z-axis elastic member are made of rubber material.

[0037] Furthermore, each column of the vibration isolation frame is provided with a foot cup at the bottom of the column that can be adjusted in height by rotation. There are four columns in number, and two parallel cross bars are connected between two adjacent columns. A three-way damping vibration isolation unit is provided on the top surface of each column, and the top surface of the corresponding column is connected to the bottom surface of the corresponding three-way damping vibration isolation unit.

[0038] In summary, the utility model has the following beneficial effects:

[0039] X-axis elastic parts: responsible for attenuating vibrations from the ground in the X direction. These vibrations may be caused by factors such as machine operation and personnel movement in the horizontal direction.

[0040] Y-axis elastic member: responsible for attenuating the vibration from the ground in the Y direction. Similar to the X-axis vibration, the Y-axis vibration also mainly comes from the interference in the horizontal direction.

[0041] Z-axis elastic parts: responsible for attenuating vibrations from the ground in the Z direction, that is, vibrations in the vertical direction. Such vibrations may be caused by vibrations of the building foundation, the passing of heavy vehicles, etc.

[0042] Before the vibration of the ground is transmitted to the optical platform, it will be attenuated by the rubber isolators in the above three directions. The viscoelastic properties of rubber materials can effectively absorb and disperse vibration energy, thereby reducing the impact of vibration on the optical platform and the equipment on it. In addition, the vibration isolation effect can be further optimized by placing the optical platform directly on the three-way damping vibration isolation bracket and selecting the appropriate support method (rigid support or rubber pad elastic support) according to actual needs.

[0043] In summary, the utility model can effectively reduce vibrations from the horizontal direction (X-axis, Y-axis) and the vertical direction (Z-axis) through a unique three-way damping and vibration isolation unit, ensuring that the equipment on the optical platform can operate stably, thereby improving the accuracy of optical path measurement and observation.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
