Abstract
The utility model discloses a mechanical metallographic specimen automatic polishing device using the magnetic force. The metallographic specimen mechanical automatic polishing device solves the key problems that a plurality of samples with different shapes and sizes are prepared when simultaneously polishing, and the trial face of the sample can obtain the polish and manufacture under an ideal state. The utility model is suitable for various material metallographic sample preparations, which is characterized in that the metallographic sample is restricted by the sample preparation disc along the dense magnetic force line part of the magnetic field. The trial face cleaved to the grinding surface of the polishing rotary plate does the right cylinder travel centripetal uniform rotation.
Description
The utility model relates to a kind of burnishing device, particularly a kind of mechanical type automatic polishing device that is used for the metallographic preparation.
The major technique feature that is used for the mechanical polishing apparatus of metallographic preparation in the prior art is that hand-held sample or mechanical type are held sample automatically.Hand-held sample normally the operator with right hand thumb, forefinger, middle finger with approximate posture of holding pen, make sample examination face and polish the rotating disk flour milling and paste mutually.And utilize the action of hand that sample is pressurizeed, and the frequent polishing direction that changes.The technical characterictic that mechanical type is held sample automatically is the shape to sample.Size has the regulation of comparison strictness.And utilize and to add severe method and in polishing process, pressurizeed in the sample top.So-called sample top is for examination face being referred to as the bottom.Hold sample as utilizing the magnetic force clamping.Be about to magnetic pull and act on the automatics that is pressurised into its major technique feature on the examination face.Still manque both at home and abroad example.
Task of the present utility model is a kind of automatics of utilizing magnetic force mechanism to finish sample polishing preparation fast with minimum stock removal and minimum deformation of design.This device can be finished many sample polishing preparations of conscientious shape, size simultaneously, and the examination face of making obtains good flatness and fineness.
Have ferromagnetic metallographic specimen with one or several and place stronger magnetic field, and with nonmagnetic substance (granite, cast stone or pottery etc.) the polishing rotating disk made separates magnetic source and sample, the sample examination is faced down, and under the effect of magnetic field, be affixed on the flour milling of polishing rotating disk.At this moment, change the pressure that magnetic field intensity just can be adjusted the examination face of acting on.If for not possessing ferromagnetic nonferrous materials, need only being embedded in it in ferromagnetic steel pipe or the cast iron pipe, polished sample gets final product.In this case, make magnetic source and sample relative position constant.When the polishing rotating disk was subjected to the power drive rotation, sample was just made smooth sliding on the rotating disk flour milling.Examination face is subjected to polishing action simultaneously.If it is equal substantially that magnetic source acts on the density of line of magnetic force at arbitrary position in the examination face scope.The perfect condition that the examination face that polishes will occur.The implication of this perfect condition is that the position of projection on the examination face at first is being subjected to rubbing down under big pressure, thereby whole examination face is flattened rapidly and is kept.In addition, making sample make just round track in polishing process on the rotating disk flour milling at the uniform velocity entad rotates.When its rotary motion trace was between the polishing rotating disk center of circle and edge, sample just ceaselessly had been changed the polishing direction.Here said entad rotation is meant sample when revolving round the sun around the center of circle of above-mentioned just round track, and self is also in rotation.Every public affairs circle just from circling.And turn to identical.It should be noted that.Sample entad can not contain the center of circle of polishing rotating disk in the circle of rotational trajectory, otherwise sample its polishing direction under said circumstances can't be changed.Because this polishing direction changes at the uniform velocity entad rotating under the prerequisite and carries out.So remarkable effect is arranged for reducing to polish the metallographic structure deformation that is caused.
The advantage of this burnishing device is: 1, can make examination face all obtain leveling on microcosmic and macroscopic view with minimum stock removal.And the examination face of leveling is kept in polishing preparation then.2, make examination face metallographic structure deformation reach the minimum degree of machine glazed finish.3, the size and dimension to sample has maximum tolerance.4, be convenient to polish simultaneously many samples.5, the sample charge and discharge operations is the most convenient, need only be placed on assigned position or take down conveniently to get final product.Because this device has above-mentioned advantage, the automaticity height can increase substantially work efficiency and sample preparation precision, reduces labour intensity, so expectation brings great convenience for metallographic researcher and worker.
Accompanying drawing 1 is the vertical view of exemplary embodiments.Accompanying drawing 2 is a front view, and all the other are sample-setting disk.
The particular content of this utility model can be provided by accompanying drawing and following exemplary embodiments.
Referring to accompanying drawing 1, magnet steel 1 is the NdFeB rear-earth magnet steel of magnetic energy product up to the 40-48 megagauss in the form of a ring, and sample-setting disk 2 is made with the Austenitic stainless steel.Both had higher-strength, and not influenced by magnetic force.Two kinds of specifications of 2 minutes Fig. 3, Fig. 4 of sample-setting disk all have 6 and put the sample hole, and each the permission places the sample hole with 1-6 sample.Sample-setting disk A(Fig. 3) is mainly used in inserting of cylinder or its approximation sample.Sample-setting disk B(Fig. 4) is mainly used in square.Inserting of cuboid or its approximation sample.For the sample of special shape, can admit in all sample-setting disks hole, all can obtain good polishing preparation.Too little ferrimagnet sample or nonferromagnetic non-ferrous metal sample must remedy with inlaying process.Polishing rotating disk 3 is cast stone or ceramic, the thick 6mm in position that is related to by sample-setting disk and magnet steel.The flour milling of polishing rotating disk 3 requires to have more than 0 grade outside the flatness, also require parallel with the lower surface, to reduce axial runout as far as possible.
The critical piece magnet steel 1 of these devices of accompanying drawing 2 expression, sample-setting disk 2, polishing rotating disk 3, unit head 4, plate rail 5, magnet steel adjusting part 6, polishing fabric 7, collar 8, main shaft 9, main shaft bolster 10, by the assembling relationship figure of the belt pulley 11 of drive power source.Wherein magnet steel 1 is coaxial with sample-setting disk 2, overlaps with the intensive place of the magnetic line of force of magnet steel to guarantee the sample rotary motion trace.This is a key.Magnet steel adjusting part 6 is used to adjust magnet steel 1 and the gap of polishing rotating disk 3, so as to making the magnetic pull intensity that acts on sample adjusted.For the requirement of magnet steel 1 and magnet steel adjusting part 6, need only make the magnetic pull that acts on sample at 0.2-2kg/cm
2Any adjustable getting final product in the scope.Magnetic pull intensity is regulated, and can the worm screw of turn-knob or small-sized handwheel be housed and the mode of the worm wheel in the magnet steel adjusting part 6 is carried out with end not.Its transmission is endless screw-worm gear-magnet steel male thread-magnet steel in proper order.In addition, in the unit head 4 micromachine is housed, drives sample-setting disk 2 and do 6-10 rev/min uniform rotation.Plate rail 5 is an active type.Can make sample-setting disk 2 upwards poplar play 90 degree so that the replacing of the replacing of sample-setting disk 2 and polishing fabric 7.Polishing fabric 7 can be selected for use according to custom and experience.Execute the cloth diamond paste and adopt the wet device of control automatically, can make polishing fabric 7 behaviours in service reach best.
