Abstract
The present invention proposes a kind of polishing nozzle, the inner surface for polishing a workpiece.Polishing nozzle includes diversion pipe, and diversion pipe includes strip and hollow cylinder and the cylinder bottom for being set to cylinder one end, the other end of cylinder are to be open, and the hollow space of diversion pipe forms runner.Multiple spray orifices are equipped with close to cylinder bottom position wherein on cylinder bottom and/or on cylinder, for the one end open of spray orifice in cylinder bottom or the inner wall of cylinder, the other end is opened on the outer wall of a bottom or cylinder.Since diversion pipe is strip, therefore it can be extend into inside workpiece, therefore work piece inner surface can be polished；The nozzle structure of present invention polishing simultaneously is very simple.
Description
Technical field
The present invention relates generally to Ultraprecise polished processing technique field, it particularly relates to which a kind of being used for buffer
The polishing nozzle of part inner surface.
Background technology
With being stepped up to parts required precision, a variety of polishing methods have been emerged in recent years.But it is most of
Polishing method is simply possible to use in the polishing of outer surface of workpiece, is not suitable for polishing work piece inner surface.The height of small size workpiece inner surface
Precision, deterministic theory are always a difficulties.
Jet Polishing method was proposed in 1998 by Fahnle et al. earliest, and method is to utilize relatively low pressure (one
As be less than 20bar) jet stream peening workpiece surface, jet stream is the polishing fluid containing abrasive grain, which can shape within the unit interval
At certain material removal amount, i.e., then so-called Material Removing Function is realized by scanning entire workpiece to entire workpiece table
Polishing (Oliver W.Fahnel, Hedeser van Brug and Hans J.Frankena. " the Fluid jet in face
polishing of optical surfaces”,Applied Optics,37(28),6671-6673,1998).This method is not
High-precision polishing only may be implemented, and the wear problem of cutter is not present in polishing process, jet stream can be real in process
When cooling down workpiece, make workpiece without Wen Sheng.Therefore, Jet Polishing is a kind of processing method with broad mass market foreground.
However, due to the limitation of the common nozzle structure of fluidic current polishing method, it is simply possible to use in the appearance of polishing workpiece
Face is not used to the inner surface of polishing workpiece；The method of other existing polishing work piece inner surfaces, mostly use expensive equipment,
Complicated technique, and fail effectively to reach nano level roughness.
Above- mentioned information is only used for reinforcing the understanding of the background to the present invention, therefore it disclosed in the background technology part
May include the information not constituted to the prior art known to persons of ordinary skill in the art.
Invention content
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure and can polish in workpiece
The polishing nozzle on surface.
The additional aspect and advantage of the present invention will be set forth in part in the description, and partly will be from description
Be apparent from, or can be through the invention practice and acquistion.
According to an aspect of the present invention, a kind of polishing nozzle, the inner surface for polishing a workpiece, including diversion pipe,
Diversion pipe includes strip and hollow cylinder and the cylinder bottom for being set to the cylinder one end, the other end of the cylinder
Hollow space for opening, the diversion pipe forms runner.Close to the cylinder wherein on the cylinder bottom and/or on the cylinder
Bottom position is equipped with multiple spray orifices, and the one end open of the spray orifice is opened in the cylinder bottom or the inner wall of the cylinder, the other end
The one end with the spray orifice of the outer wall of the cylinder bottom or the cylinder, the diversion pipe can be extend into the workpiece.
As shown from the above technical solution, the present invention has at least one of following advantages and good effect：The present invention is thrown
Light nozzle includes diversion pipe, and diversion pipe is interior with runner and with the multiple spray orifices being connected to runner, using polishing liquid energy to work
Part surface is polished.Since diversion pipe is strip, it can be extend into inside workpiece, therefore can be thrown to work piece inner surface
Light；The nozzle structure of present invention polishing simultaneously is very simple, and polishing process is also simplified.
