Air flotation four-dimensional adjusting platform

Abstract

The invention provides an air flotation four-dimensional adjusting platform and belongs to the field of air flotation equipment. The air flotation four-dimensional adjusting platform comprises a mounting base and a transition sliding platform; the mounting base is in a hollow cylindrical shape; the transition sliding platform comprises an air flotation plate at the upper end and a transition column which is perpendicularly arranged under the air flotation plate; the transition column and the mounting base are coaxially arranged; a moving gap is formed between the transition column and the mounting base; the air flotation plate covers the upper end surface of the mounting base; the surface between the air flotation plate and the mounting base is an air flotation surface; adjusting threadedrods connected through threads are arranged on the mounting base; the adjusting threaded rods are in contact with the transition sliding platform after penetrating through the mounting base; the number of the adjusting threaded rods is at least two; the two adjusting threaded rods are arranged to have an included angle of 90 degrees in the same horizontal plane; an angle sliding platform in contact with the spherical surface is arranged at the upper end of the transition sliding platform; an air flotation surface is arranged between the angle sliding platform and the transition sliding platform; and the rotation of the transition sliding platform is adjusted by using an angle adjusting rod. According to the air flotation four-dimensional adjusting platform, workpiece clamping position accurate and fine adjustment during part machining, measuring and precision repairing can be realized, and the part manufacturing and measuring accuracy is improved.

Description

technical field [0001] The invention belongs to the field of air flotation equipment and relates to an air flotation four-dimensional adjustment table. Background technique [0002] The application of air flotation mechanical equipment is becoming more and more widespread, which can greatly reduce the friction between two parts, ensure the stability of relative movement of parts, and save energy consumption. The working principle of air flotation is to set up air flotation channels on the parts below , and blowing air downward through the air flotation channel, the upper part under the action of the gas greatly reduces the friction between the upper and lower parts, which is beneficial to the micro adjustment of the upper part. [0003] At present, precise positioning and adjustment are required in the processing and testing of large-caliber, high-precision and complex parts. After adjustment, it needs to be locked. The traditional thinking of purely mechanical adjustment is...

Problems solved by technology

[0003] At present, precise positioning and adjustment are required in the processing and testing of large-caliber, high-precision and complex parts. After adjustment, it needs to be locked. The traditional thinking of purely mechanical adjustment is too slow, and the adjustment accuracy is not easy to guarantee. Large-scale When complex parts are large in size or heavy in weight, the power requirements for the driving source for adjustment are high, and the energy consumption is large
