The air polishing device for the micropore comprises a polishing nozzle; a workpiece is arranged below the polishing nozzle and is arranged on a workpiece clamping connection disk, and the workpiece and the workpiece clamping connection disk are sealed through a seal ring; the workpiece clamping connection disk is arranged on a sealed cabin which is provided with an air outlet; the air outlet is provided with an air pressure regulating valve which is fixed through an air valve; an air outlet filter net is arranged below the air outlet; the polishing nozzle is provided with an air inlet and a feed port; and an angle between the axial direction of the air inlet and the axial direction of the feed port is less than or equal to 90 degrees. The air polishing device can polish thin and long micropores of less than 2 millimeters in machinery parts to reach any surface roughness grade, overcomes the defect that liquid turbulently flows in the process of polishing the long and thin micropores by fluid, the process, and the facilities are simple, the design is reasonable, the roughness of the inner surface of the micropores of a central spindle is improved, and the inner holes are smooth and attractive.
Description
Technical field
The present invention relates to a kind of burnishing device, specifically, the present invention relates to a kind of micropore gas burnishing device.
Background technology
At present, on the engineering goods part, process if having less than 2 millimeters aperture, then all adopt drill bit or perforation processing, when these hole surface roughness require to reach Ra0.8 when above, generally adopt grinding rod to add the polishing process method of abrasive pastes, not only man-hour, long and Grinding Quality was difficult to guarantee; In addition, when draw ratio to 30 is above, then can't realize processing; In the endoporus polishing, also have a kind of fluid polishing now, promptly add abrasive pastes by liquid and carry out glossing, this technology is not only to outside the polissoir configuration requirement height, and some elongated micropores easy turbulent flow that forms under high pressure conditions, can't reach high-quality polishing effect.Therefore, in some important precision optical machinery fields, in spools such as space flight, aviation, automobile, chemical industry, hydraulic pressure, often to requiring to reach Ra0.4 less than 2 millimeters micropore surface roughness in these mandrels, even when higher, then can't realize processing, this also directly influences the quality raising of China to these mandrels, and the supporting cooperation of the outlet in these fields.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can to the aperture less than 2 millimeters micropore carry out the gas polishing a kind of micropore gas burnishing device.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions.
This micropore gas burnishing device comprises the polishing mouth, and described polishing mouth below is provided with workpiece; Described workpiece is installed on the piece-holder terminal pad, between seal by sealing ring; Described piece-holder terminal pad is installed on the sealed compartment; Also be provided with the gas outlet on the described sealed compartment, be provided with air pressure regulator on the gas outlet, described air pressure regulator is fixed by the air valve contiguous block; Below the gas outlet, be provided with the gas outlet filter screen.
In order to guarantee entering of gas communication and abrasive material, described polishing mouth is provided with air inlet and charging aperture.
In order to control the inlet of abrasive material, described air inlet and charging aperture axially between angle smaller or equal to 90 degree.
Compared with prior art, usefulness of the present invention is: adopting can be to carrying out the polishing of any roughness grade after this structure less than 2 millimeters elongated micropore in the component of machine, also solve simultaneously the drawback that turbulent flow can appear in liquid in the elongated micropore of fluid polishing, technology is succinct, facility is simple, reasonable in design, improved the roughness of mandrel micropore inner surface, make its endoporus smooth, attractive in appearance.
