Abstract

The invention discloses a kind of turbomolecular pump damper, including flange one, cylinder one, corrugated stainless steel tubing, rubber filling object, cylinder two and flanges two.Turbomolecular pump damper provided by the invention, it is sealingly connected with scanning electron microscope sample room and turbomolecular pump respectively by upper and lower two flanges, by the collective effect of corrugated stainless steel tubing and rubber filling object, the vibration that turbomolecular pump generates during operation can be effectively prevented and transmitted to scanning electron microscope sample room.The installation that the present invention completes turbomolecular pump again while solving the problems, such as turbomolecular pump damping is fixed, and the complexity of assembling process is greatly simplified.

Description

Turbomolecular pump damper
Technical field
It is specifically a kind of for reducing the vibration generated in turbomolecular pump operating the present invention relates to a kind of dampening arrangement The device transmitted to scanning electron microscope sample room.
Background technique
The amplification factor of electron microscope is up to hundreds of thousands times, and any vibration of sample can all directly affect image quality, This requires putting the sample stage of sample to have the characteristics that high stability, but for multi-angle, multiposition observes sample, modern Electron microscope sample desk is mostly 5 axis cantilever designs, is needed using linear guide, these components have low damping characteristic, can be produced Raw microvibration.
Scanning electron microscope requires work under vacuum conditions, needs to continue working using turbomolecular pump, molecular pump Vacuum is obtained by high-speed rotating turbo blade, turbomolecular pump can inherently generate vibration, if in turbomolecular pump and swept Retouching between electron microscope sample room does not have damping device, can seriously affect image quality.
It is undesirable all to there is damping effect in current vibration reducing measure, and installation is complicated, problem at high cost.
Summary of the invention
The present invention aiming at the above shortcomings existing in the prior art, provides a kind of turbomolecular pump damper.
The present invention is achieved by the following technical solutions.
A kind of turbomolecular pump damper, including flange one, cylinder one, corrugated stainless steel tubing, rubber filling object, cylinder two And flange two, in which:
Flange one, material are 316L stainless steel, and Laser Welding welding fabrication is used between the flange one and cylinder one;
Cylinder one, material are 316L stainless steel, and laser is respectively adopted between the cylinder one and flange one and corrugated stainless steel tubing Weld welding fabrication;
Corrugated stainless steel tubing, material are 316L stainless steel, explosive forming, wall thickness 0.25mm ~ 0.35mm, the corrugated stainless steel tubing Laser Welding welding fabrication is respectively adopted between cylinder one and cylinder two;
Rubber filling object, material are fluorubber, and with corrugated stainless steel tubing using disposable whole cast molding, combining closely becomes One entirety;
Cylinder two, material are 316L stainless steel, and laser is respectively adopted between the cylinder two and flange two and corrugated stainless steel tubing Weld welding fabrication;
Flange two, material are 316L stainless steel, and Laser Welding welding fabrication is used between the flange two and cylinder two.
Further, the rubber filling object and corrugated stainless steel tubing are using disposable whole cast molding.
Further, Laser Welding welding fabrication is respectively adopted between the corrugated stainless steel tubing and cylinder one and cylinder two.
Further, Laser Welding welding fabrication is used between the flange one and cylinder one.
Further, Laser Welding welding fabrication is used between the flange two and cylinder two.
Turbomolecular pump damper provided by the invention, by upper and lower two flanges respectively with scanning electron microscope sample Product room and turbomolecular pump sealingly connect, and by the collective effect of corrugated stainless steel tubing and rubber filling object, can be effectively prevented The vibration that turbomolecular pump generates during operation is transmitted to scanning electron microscope sample room.
The installation that the present invention completes turbomolecular pump again while solving the problems, such as turbomolecular pump damping is fixed, greatly Ground simplifies the complexity of assembling process.
