Description
Technical field
The present invention relates to a kind of equipment for metallography microscope sample mechanical polishing, particularly a kind of design of metallography microscope sample pre-mill.
Background technology
In order to differentiate metallographic microstructure and study, need the sample first analyzed metal material being prepared into certain size, being observed by metaloscope through grinding, after the operation such as polishing and corrosion, analyzing metal microstructure and distribution situation thereof.Grinding is to obtain smooth flour milling, for polishing is prepared, is generally divided into corase grind and fine grinding, the darker polishing scratch stayed when the object of fine grinding is and eliminates corase grind.The fine grinding commonly used has manual polishing and mechanical polishing, and both all need hand-held sample: manual polishing is that one direction passing grinds on abrasive paper for metallograph, mentions sample, make it to depart from sand paper when retracting; Mechanical polishing is gently pressed in by sample flour milling to post on the pre-mill of sand paper, and utilize the sand paper rotated that metallographic specimen is levigate, conventional equipment is disc type pre-mill.
Although disc type pre-mill can improve grind efficiency, but requirement prepared by the metallographic specimen that sometimes can not meet degree of precision, because it can not ensure sample cut in the same direction, and rotational speed is different everywhere due to disk, and thus the roughness of specimen surface also seems even not.Meanwhile, disc type pre-mill generally needs hand-held sample, and this not only easily causes the inclination of sample and steps on limit, but also there is the risk that sample taken out of by high speed rotating plate.If publication number is CN102528612A, patent name is the patent of " a kind of Linear reciprocating type pre-milling machine ", reciprocating mechanism is utilized to make grinding platform do straight reciprocating motion, although which ensure that specimen surface cut in the same direction, but because metallographic specimen is manual clamping, thus easily cause the inclination of sample and step on limit, and there is certain danger.Publication number is CN103234800A, patent name is the patent of " a kind of pre-grinding test sample of gold phase machine ", utilize specimen holder to avoid and manual clamping is carried out to sample grinding in process, time saving and energy saving, but the structure of whole pre-mill is very complicated, kinematic train is more, meanwhile, in the friction process of sample and sand paper, the size of sample is in continuous reduction, and sample is just fixed by clamping device that this patent adopts in advance, be thus difficult to ensure that sample is in fit-state with sand paper all the time.In addition, also there is two problems in above-mentioned two patents simultaneously: one be reciprocating mechanism used is slider-crank mechanism in essence, and this mechanism is difficult to ensure that slide block at the uniform velocity moves back and forth in fact, thus cannot ensure that sample grinds even surface roughness.If attempt to realize at the uniform velocity moving back and forth of slide block by Electric Machine Control, then higher to the requirement of motor, cost is larger; Two is do not have to solve grinding the heating problem of sample in process and grinding off the washing problems of the grains of sand, sample thus cannot be avoided to be heated and to cause tissue change, coarse sand grain also cannot be avoided to take in fine grinding operation, cause the polishing scratch being difficult to eliminate.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of metallography microscope sample pre-mill, specimen surface cut can be ensured in the same direction, make specimen surface roughness even, can mechanical grip be realized again and keep sample and sand paper to be in fit-state, can also solve and grinding the heating problem of sample in process and grinding off the washing problems of the grains of sand.
