Abstract

The invention relates to a two-dimensional plane air-floatation zero-gravity cradle which comprises two long-distance air-floatation linear guide rails, a Y-axis air-floatation axle, a Y-axis air-floatation sleeve and a hanging rope, wherein at least two X-axis air-floatation sleeves are sleeved on an X-axis air-floatation axle, the X-axis air-floatation sleeves are all connected with an air storage sleeve in a sealing way, an installing slide block is slidably arranged on the long-distance air-floatation linear guide rails and is connected with a drive mechanism in a drive way, the slide block is fixedly connected with the X-axis air-floatation axle, an air storage cavity is arranged between the air storage sleeve and the X-axis air-floatation axle, the axle center of the X-axis air-floatation axle is provided with an air inlet channel which is communicated with the air storage cavity, the air storage cavity is provided with an air outlet which is communicated with an air inlet of each X-axis air-floatation sleeve through a connecting air pipe; the air storage sleeve is fixedly connected with supports, the two supports are respectively sleeved at two ends of the Y-axis air-floatation axle, the Y-axis air-floatation sleeve is sleeved on the Y-axis air-floatation axle, and the Y-axis air-floatation sleeve is connected with the hanging rope. The invention can effectively avoid additional influences on friction force and inertia force, and is suitable for high-precision occasions.

Description

technical field [0001] The invention relates to an air flotation device, in particular to a two-dimensional zero-gravity hanger composed of air flotation guide rails. Background technique [0002] There are many ways to achieve zero gravity. The zero-gravity environment of the free-falling process can be used, and the buoyancy of the fluid can be used to offset part of the gravity effect. However, the most commonly used method in engineering is to perform gravity unloading on the limited structural points of the specimen. According to the movement trajectory of the suspension point of the mechanism, the deployment device can be divided into one-dimensional suspension device (linear motion) and two-dimensional suspension device (plane motion). The one-dimensional suspension device has only one direction of follow-up for the suspension beam, and no follow-up in the other direction, while the two-dimensional suspension beam must ensure follow-up in both directions. The inventi...
