Adopting air springs and rubber springs for joint load-bearing, and using imported high-quality airbags, it has a large load-bearing capacity and good vibration isolation performance. There are multiple options for table size, with a thickness of 150/200/250mm. The upper surface is made of high-quality ferromagnetic stainless steel, with a conventional thickness of 6mm. It is precision ground to ensure good flatness. The surface is covered with M6 threaded holes with a pitch of 25mm, and the installation hole is 37.5mm away from the edge of the platform, making it convenient for the use and construction of various instruments. The inner core of the table is a welded honeycomb structure, and the air floating bracket adopts air springs. The interior of each support column is an independent sealing structure, which forms an air floating isolator with air springs. The optimized isolator ensures high stability and good isolation effect of the overall structure. The air suspension isolation platform is generally equipped with an electric inflation pump as standard, and does not require a fixed air source to maintain stability.

Introduction:
Optical platforms are widely used in fields such as optics, electronics, precision mechanical manufacturing, aerospace, precision chemical engineering, non-destructive testing, and biochemical research. Their dynamic mechanical properties directly affect the accuracy and reliability of test results.
Working principle of optical platform:
Vibration is ubiquitous, and mechanical vibration is the reciprocating motion of an object (or a part of an object) near its equilibrium position. The optical platform is mainly used to eliminate the interference of vibration on the equipment on the workbench. The vibration interference force generally comes from three aspects: 1. the impact force generated on the workbench during use and operation, 2. the interference force generated by the movement of moving parts in experiments, and 3. the interference force from the ground or floor during use and operation.
The rubber or air isolation springs in the support components of the optical platform effectively prevent interference from the ground and the outside on the workbench, while the honeycomb structure inside the optical platform table can effectively absorb the interference force uploaded from the workbench.
Product structure of optical platform:
The optical platform is composed of a workbench and supporting components. The working surface of the workbench is made of high-quality high magnetic stainless steel plate, the bottom plate is made of high-quality steel plate, and the middle is welded or bonded with rib plates and rib plates. The specific components are as follows:
1. Working surface: The welding type adopts high-quality high magnetic conductivity stainless steel plate with a thickness of 5-8mm, while the bonding type adopts 430 high magnetic conductivity nickel alloy stainless steel with a thickness of 4-6 mm. After precise grinding and deburring, good flatness and roughness are obtained, and a smooth but non reflective surface is ensured.
2. Installation holes: The holes on the countertop are vertical threaded holes, and the ports are countersunk holes to remove burrs. The general specification is M6 threaded holes with a hole spacing of 25x25mm, and other types can be customized according to customer requirements. The installation hole is located directly above the core compartment, ensuring that the screw can be inserted to a sufficient depth.
3. Bottom plate: Made of high-quality medium carbon steel plates with a thickness of 5-8mm, in order to achieve the same coefficient of thermal expansion, ensure structural integrity, prevent internal stress accumulation under temperature cycling conditions, and ensure good load-bearing capacity.
4. Core: The welded optical platform core is made of steel plate, which is electroplated to prevent corrosion. It is welded into a well shaped honeycomb structure. The bonded optical platform core is made of 0.25mm thick stainless steel plate honeycomb bonding, greatly improving structural strength and reducing weight. The upper surface of the bonding platform core is bonded with a layer of support plate with a sealing cup, which can prevent dust and other debris from entering the interior of the workbench and is easy to clean. The stamping forming of the supporting plate sealing cup ensures structural strength and improves the vibration isolation effect of the platform.
5. Side wall: The side wall is used to close the inner core of the countertop, with an inner layer made of medium carbon steel plate to achieve the same thermal expansion. The outer layer is made of black rock texture effect, and has a hollow logo to ensure the overall aesthetics.
Main parameter inspection methods and processes for optical platforms:
1, Flatness of optical platform
Flatness: Generally refers to the variation of the actual surface being measured from its ideal plane. Flatness error refers to the comparison between the actual surface being measured and the ideal plane, and the line value distance between the two is the flatness error value. Alternatively, by measuring the relative height difference of several points on the actual surface, the flatness error value can be converted into a line value.
Flatness detection methods: flat crystal interference method, liquid plane method, surface measurement method, and flat ruler detection method. Generally, the latter two detection methods are commonly used.
1. Meter measurement method
Standard:<0.05mm/1000mm
2. Flat ruler inspection method
Standard:<0.05mm/1000mm
2, Surface roughness of optical platform
Roughness: refers to the unevenness of the machined surface with small gaps and small peaks and valleys. The distance (wave distance) between its two peaks or valleys is very small (below 1mm), which belongs to micro geometric shape error. The smaller the surface roughness, the smoother the surface. Measurement methods: light needle method, light cutting method, comparison method, roughness meter detection method, usually using the last two detection methods.
1. Comparison method: The comparison method is easy to measure and is used for on-site measurements in the workshop. It is commonly used for measuring medium or rough surfaces. The method is to compare the measured surface with a roughness sample marked with a certain value to determine the roughness value of the measured surface. The methods that can be used for comparison are: measuring when Ra>1.6 m, using a magnifying glass when Ra 1.6~Ra 0.4 um, and using a comparison microscope when Ra<0.4 μ m.
When comparing, it is required that the processing method, texture, direction, and material of the sample be the same as the surface of the tested part.
2. Roughness meter detection method: Place the roughness meter on an optical platform and read the measurement data.
