Self-balance vibration isolation platform of air cushion type

Abstract

The invention provides a self-balance vibration isolation platform of an air cushion type, and the vibration platform comprises a support column. The support column is connected with a support platform, and the support platform is provided with a working platform. Elastic support legs are disposed at two ends of a space between the support platform and the working platform, and the central part ofthe space is fixedly provided with an adjustment device. The interior of the working platform is provided with a horizontal detector, and the central part of the supporting platform is connected witha mute air pump. The lower end of the mute air pump is provided with a vibration isolation bottom plate, and the bottom of the support column is provided with a shock pad. The beneficial effects of the invention are that the interior of the support column is provided with a damping material; a horizontal detector can visually observe the horizontal stable performance of the working platform, andcan achieve the timely adjustment; moreover, a multiple support damping device reduces the external vibration, thereby avoiding a big error of an experiment result.

Description

technical field [0001] The invention belongs to the technical field of optical test equipment, in particular to an air cushion type self-balancing vibration isolation platform. Background technique [0002] With the development of science and technology, optical platforms have been widely used in optics, electronics, precision machinery manufacturing, metallurgy, aviation, aerospace and other fields. For example, in the key positions of precision testing and equipment vibration isolation, its stability directly affects Accuracy and reliability of test results. In optical experiments, the optical table is an extremely precise experimental equipment. It needs to have high vibration resistance and shape stability. It is composed of an optical table and a supporting structure. [0003] At present, there are the following types of vibration isolation methods for optical tables: damping vibration isolation and air flotation vibration isolation.

AI Technical Summary

Problems solved by technology

[0003] At present, there are the following types of vibration isolation methods for optical platforms: damping vibration isolation and air flotation vibration isolation. These types of vibration isolators are used as supports, which consume materials, are difficult to process, and cost high.

At present, the horizontal position of the optical table cannot be fine-tuned, and there is no corresponding horizontal position detection device, which is not conducive to the conduct of optical experiments, and in some places with high vibration requirements, when disturbed by slight external vibrations, the results of optical experiments will not be correct. There will be a large error, which will affect the final experimental results.
