Problems solved by technology
However, in the traditional detection method, since the direction of the measured axis is fixed, the position of the detection equipment is also relatively fixed, which cannot satisfy the detection of the rotation accuracy of the air bearing with the condition of spatial flip motion.

The invention belongs to the technical field of air bearing precision detection, and particularly relates to an air bearing revolving precision detection device which can smoothly complete detection of the revolving precision of an air bearing under the condition of space overturning movement. The air bearing revolving precision detection device comprises a photoelectric autocollimator, a gantry support, a plane mirror tool, two technical shafts, a detected air bearing shafting and a simulation support. The detected air bearing shafting is installed in the simulation support through the two technical shafts. The gantry support is installed on the detected air bearing shafting. The photoelectric autocollimator is installed on the gantry support. The plane mirror tool is arranged between the position above the detected air bearing shafting and the gantry support. The two technical shafts are assembled in a branch bearing pedestal simulation support.
Description
technical field [0001] The invention belongs to the technical field of air bearing precision detection, and in particular relates to a detection device for the rotation precision of an air bearing under the condition of space flipping motion. Background technique [0002] Because air bearings use low-viscosity air as the lubricating medium, they have many advantages compared with traditional bearings, such as low friction, high speed, high precision and stability, and small temperature rise. Therefore, air bearings are widely used in High-precision support, precision machining platform and many other fields. [0003] For the most important index in air bearings—the detection of rotation accuracy, since the rotation axis of air bearings is relatively fixed when in use, the commonly used detection methods are only effective for this single working condition, such as working under the condition that the rotation axis is vertical If the air bearing is qualified when the rotary ...
