Description

Technical Field

[0001] The utility model belongs to the technical field of optical platform vibration reduction panels, in particular to an optical platform panel with a multi-truss honeycomb core. Background Art

[0002] Optical platforms, also known as optical breadboards, optical desktops, scientific desktops, and experimental platforms, are used in teaching, scientific research, and production activities in ultra-precision optics, biology, physics, imaging, and testing. They provide a level and stable table surface, and generally require vibration isolation to ensure that they are not disturbed by external factors and that scientific experiments can proceed normally.

[0003] Most existing optical platform panels are honeycomb cores with curved corners or square "well"-shaped cores. Both types of panels are hollow, have poor damping, and are not strong enough. This makes the panels susceptible to vibrations caused by external interference during use, resulting in poor vibration reduction and an inability to meet the needs of ultra-precision experiments. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides an optical platform panel with a multi-truss honeycomb core. The panel of the present invention has a good damping effect, higher static and dynamic stiffness, and higher single-point load-bearing capacity.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An optical platform panel with a multi-truss honeycomb core comprises a main body, which includes four side panels and a multi-truss honeycomb core. The four side panels enclose a square frame structure, and the multi-truss honeycomb core is filled within the frame structure. The multi-truss honeycomb core is composed of several rows of honeycomb cores and several trusses. A truss is connected through the middle of each row of honeycomb cores, and adjacent rows of honeycomb cores are connected to the same truss. The honeycomb core is filled with foam damping.

[0007] Preferably, the trusses and the side panels are both made of stainless steel plates, and both ends of each truss are fixedly connected to the inner sides of two oppositely arranged side panels.

[0008] Preferably, each row of honeycomb cores is composed of a number of honeycomb core panels connected in sequence, the honeycomb core panels are hexagonal and composed of six stainless steel core panels coated with epoxy resin, and each row of honeycomb cores is arranged along the length direction of the truss.

[0009] Preferably, the thickness of the stainless steel core plate is 0.25 mm.

[0010] Preferably, the main body also includes a top plate and a bottom plate, which are respectively arranged at the top and bottom of the frame structure, so that the top plate, the bottom plate and the four side plates enclose a hollow cavity, and the multi-truss honeycomb core is arranged in the cavity.

[0011] Preferably, a plurality of M6 threaded holes are provided on the top plate.

[0012] Preferably, the thickness of the top plate and the thickness of the bottom plate are both 5 mm.

[0013] The advantages of the present invention are:

[0014] (1) The utility model fills the interior of the multiple truss honeycomb core with foam damping, which can improve the damping effect of the panel and make the panel have better vibration reduction effect. The multiple truss honeycomb core can improve the stiffness and stability of the panel, increase the fitting area between adjacent honeycomb cores, and make the panel have higher static and dynamic stiffness and higher single-point load-bearing capacity.

[0015] (2) The entire panel of the utility model is made of stainless steel, and the thickness of the top plate and the bottom plate are both 5mm, and the thickness of the stainless steel core plate is 0.25mm. Compared with the existing 4-5mm thick "well" shaped rib plate structure panel, the panel's self-weight is greatly reduced and the panel's energy consumption capacity is improved.
