Description
Technical field
The utility model relates to a kind of new burnishing device, belongs to the polishing manufacture field.
Background technology
Magnetic flow liquid is a kind of intellectual material.It is by high magnetic permeability, the small soft magnetic particles of low magnetic hysteresis property and the suspended substance that the non-magnetic liquid mixing forms.It is liquid under normal conditions, when adding loaded magnetic field, liquid-solid phase can take place become, and type of becoming solid, its apparent viscosity improves a lot, and shows the character of shearing resistance.When removing demagnetizing field, solid-liquid phase takes place again to be become, become liquid.In certain magnetic field intensity scope, the apparent viscosity of magnetic flow liquid is relevant with magnetic field intensity, and this phenomenon is called magnetic rheology effect.
Magnetic flow liquid can be used for polishing manufacture field.Method is in magnetic flow liquid, to sneak into abrasive grain, places magnetic field, when magnetic rheology effect takes place, forms soft grinding head, and the relative motion between dependence and the workpiece is carried out polishing operation to workpiece.Compare with common finishing method, magnetorheological polishing has following advantage:
(1) the face type posts, and does not change the workpiece surface figure accuracy;
(2) abrasive material has from sharp ability for discrete abrasive material, and it is stable to remove function, is applicable to digitlization processing;
(3) hardness of bistrique is adjustable.Only needing to regulate magnetic field intensity is scalable bistrique hardness;
(4) contactless polishing can not produce the lower surface breakable layer;
(5) bistrique does not have wearing and tearing.
Magnetorheological polishing is similar to the extruding polishing, and the polishing clearance is obeyed the Preston empirical equation, and polish pressure and relative rotation speed have direct influence to its clearance.
In general, for specific polishing tool, its clearance model is changeless, in order to obtain higher surface quality, needs to carry out trajectory planning according to the curved surface information of removing model and polish.But because the limitation on the principle is difficult to obtain controlled high-precision surface quality.
The employed rubbing head of Technique of Magnetorheological Finishing is made up of intellectual material-magnetic flow liquid.The hardness of rubbing head can be controlled through changing magnetic field intensity, and magnetic field intensity can be controlled through changing convenient adjusting of solenoid voltage method.Owing to this character of magnetic flow liquid, can in polishing process, initiatively change the Distribution of Magnetic Field of polish, make it in polish, have uniform clearance model.In view of this consideration, invented the controlled magnetorheological uniform polish device of a kind of clearance model.
Summary of the invention
