Abstract

The invention relates to a testing device, in particular to air bearing part fit testing equipment, which comprises a tank body, a microphone, sound insulation pipelines, a mounting platform, a shock insulation substrate and a driving device, wherein the mounting platform is positioned in the tank body, penetrates through the tank body and is fixedly arranged on the shock insulation substrate outside the tank body, and an air bearing is arranged on the mounting platform; the sound insulation pipelines sleeve the two sides of the air bearing, and are communicated with an atmosphere outside the tank body, and the driving device is arranged outside the tank body and is connected with the air bearing in the tank body through a driving shaft; the microphone is arranged in the tank body through a metal hose. According to the testing equipment provided by the invention, the microphone is adjusted as close as possible around the air bearing, and the driving device outside the tank body drives the air bearing to move so as to simulate the working condition of the air bearing; the audio condition of the air bearing in each position in the working process can be measured by the microphone, the internal clearance uniformity and the fitting degree of the air bearing and the like can be obtained by audio analysis, and the testing precision is high and the effect is good.

Description

Technical field [0001] The invention relates to a detection device, in particular to an air bearing performance detection device. Background technique [0002] In recent years, air bearings have been widely used in high-precision manufacturing due to their frictionlessness, high precision, strong load-bearing capacity, and low power consumption. The existing air-floating bearings can reach nanometer-level air gaps, so air bearings The components have high processing requirements. [0003] The finished air bearing shall undergo a series of performance tests to ensure that the air bearing clearance meets the accuracy requirements. There are currently some static pressure air bearing detection methods and devices, but the air bearing is generally in a dynamic state during the working process, and external interference conditions such as sensors cannot be introduced during the test. Therefore, the detection of air bearing is also a current problem. In particular, there is no complete...
