Description
Technical field
The utility model relates to the coarse performance testing device of a kind of material surface, particularly a kind of automobile coarse performance testing device of Nd-Fe-Bo permanent magnet material.
Background technology
The application and development of neodymium iron boron (NdFeB) permanent magnetic material is very rapid in recent years, as the strongest present magnetic material, has been widely used in all fields such as electroplating device, machinery, medical treatment, automobile, and application prospect is very wide.Nd-Fe-B permanent magnet mainly is assemblied in electric motor of automobile, automobile sparking coil, alternator, the sensor equipment.
Surfaceness refers to less spacing and small peak valley unevenness that finished surface has.Distance (pitch of waves) very little (below 1mm) between its two crest or two troughs with the naked eye be nondescript, so it belongs to the microcosmos geometric shape error.Surfaceness is less, and then the surface is more smooth.The size of surfaceness has a great impact the usability of mechanical component, is mainly manifested in the following aspects: the 1) wearing quality of surface roughness affect part.The surface is more coarse, and the effective contact area between matching surface is less, and pressure is larger, and wearing and tearing are just faster.2) stability of surface roughness affect fiting property.Concerning clearance fit, the surface is more coarse, and is just more easy to wear, and course of work intermediate gap is increased gradually; Concerning interference fit, during owing to assembling that the protruding peak of microcosmic is crowded flat, reduced actual effective interference, reduced bond strength.3) fatigue strength of surface roughness affect part.There is larger trough in the surface of coarse part, and they are the same with crackle as the wedge angle breach, and counter stress is concentrated very sensitive, thereby affects the fatigue strength of part.4) corrosion resistivity of surface roughness affect part.Coarse surface easily makes corrosive gas or liquid penetrate into the metal internal layer by the microcosmic trench on surface, causes surface corrosion.5) sealing of surface roughness affect part.Can't fit closely between the coarse surface, gas or liquid are by the gap leakage between surface of contact.6) contact stiffness of surface roughness affect part.Contact stiffness be the part faying face under external force, the opposing juxtaposition metamorphose ability.The rigidity of machine depends on the contact stiffness between each part to a great extent.7) affect the measuring accuracy of part.The surfaceness of part measured surface and survey instrument measurement face all can directly affect the precision of measurement, especially when precision measurement.In addition, surfaceness resistance that plating coating, thermal conductivity and contact resistance, reflection potential and the radiance of part, liquids and gases are flowed, the circulation of conductive surface electric current etc. all can have impact in various degree., measure with the rough surface performance of Nd-Fe-B permanent magnet automobile with the consistance of the coarse performance of surface of Nd-Fe-B permanent magnet in order to guarantee automobile.
The utility model content
