A kind of pneumatic suspension assembly and the air suspension laser cutting dust removal device comprising it

Abstract

The utility model discloses a kind of pneumatic suspension assemblies, for gas-suspended laser cutting dust removal device, the pneumatic suspension assembly, including upper pneumatic suspension assembly, and with the symmetric design lower pneumatic suspension assembly of upper pneumatic suspension assembly;The lower pneumatic suspension assembly includes lower cavity air inlet, lower cavity air outlet, lower cavity plate, lower suspension plate;The lower suspension plate is structured with positive pressure flow channel and negative pressure flow channel, the positive pressure flow channel and the negative pressure flow channel are alternately spaced arrangement;Positive pressure gas can sequentially enter the positive pressure flow channel from the lower cavity air inlet and act on the lower surface of pole piece to form gas mold, and the gas mold excess gas is sucked away by negative pressure flow channel through the lower cavity air outlet under the action of negative pressure;The upper pneumatic suspension assembly has the same effect. By adopting the technical means of combining positive pressure and negative pressure, the stability of gas film is improved, and the problem of unstable operation of pole piece in the gas-suspended state in the prior art is solved.
