Description
Technical field
The utility model relates to a kind of sample preparation auxiliary clamp being applicable to irregularly shaped sheet sample.
Background technology
Due in recent years, Materials and application are more and more quicker and extensive, to such an extent as to investigation of materials is further frequent, and wherein different material sample is brought up to experimental bench.But for some very thin samples and need to polish bottom surface on it, but it is difficult to directly take fixing with hand, so these difficult problems have just inspired the demand of researcher for clamping device.For laminar metallographic sample preparation, conventional method of preparing sample is convenient to hand-held object is polished at certain by sample 502 gluings.But due to desktop tilt or sample itself angle of inclination again or mill time exert oneself unequal factor, cannot ensure that the face ground is flat, follow-up metallographic observation or scanning electron microscopic observation can be affected.
Researchers repeatedly can use in the urgent need to a kind of and do not damage again the fixture of sample while fixing little material sample easy and simple to handle, then allow sample can carry out polishing sample preparation on the sand paper of different thicknesses or sample grinding machine.The utility model is exactly to solve such sample preparation problem making numerous experimenter have a headache for it.
At present, China Patent No. 201120541173.6 discloses a kind of fixture being applicable to laminar metallographic specimen and grinding, fixture by Al alloy block, rectangle groove, screw hole form, structure is simple, easy and simple to handle, but for some very thin samples, it may not necessarily be fixed with screw, easily cause unbalance stress, the problems such as bevelling.
Utility model content
Technical problem to be solved in the utility model is to provide simple, the easy to use sample preparation auxiliary clamp being applicable to irregularly shaped sheet sample of a kind of structure.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of sample preparation auxiliary clamp being applicable to irregularly shaped sheet sample, comprise the strip shape body in order to be clung irregularly shaped sheet sample by viscose glue, outside described strip shape body, be arranged with the ring bodies held.
Further, described ring bodies is Back Word shape, and its outline is square; Described strip shape body is rectangular-shaped.
Further, described strip shape body and ring bodies are matched in clearance, and its gap is less than 1mm.
Further, described strip shape body and ring bodies are made up of aluminum alloy materials.
Compared with prior art, the utility model has following beneficial effect: the utility model thickness and grinding can need the difference in height adjusting strip shape body and ring bodies per sample, be suitable for, solve hand-held polishing, the problem of sample flour milling injustice, there is cheap, easy to make, simple to operate, to be easy to eliminate cut advantage, and material sample sample preparation effect is good, not fragile.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Detailed description of the invention
As shown in Fig. 1 ~ 4, a kind of sample preparation auxiliary clamp being applicable to irregularly shaped sheet sample, is comprised the strip shape body 1 in order to be clung irregularly shaped sheet sample 3 by viscose glue, is arranged with the ring bodies 2 held outside described strip shape body 1.
In the utility model, described ring bodies 2 is in Back Word shape, and its outline is square, because the outline of ring bodies 2 is for being square, is easy to 90-degree rotation and eliminates cut when polishing; Described strip shape body 1 is in rectangular-shaped; Three-back-shaped ring bodies 2 can carry out stable holding to strip shape body 1, make strip shape body 1 can with sand paper perpendicular contact, ensure the planarization in the face that institute grind away product 3 contact with sand paper.
In the utility model, described strip shape body 1 is matched in clearance with ring bodies 2, and its gap is less than 1mm; Because strip shape body 1 outer wall and ring bodies 2 inwall almost coincide, so the bottom surface total energy keeping parallelism of strip shape body 1 and ring bodies 2, even if desktop injustice also can ensure that the face of the metallographic specimen ground is flat like this.
In the utility model, in order to reduce material cost and processing cost, described strip shape body 1 is formed through linear cutter by aluminum alloy materials with ring bodies 2, can reach good required precision.
The concrete use procedure of the utility model is as follows: when carrying out metallographic or scanning electron microscopic observation, for common AZ31 magnesium alloy, when only carrying out mechanical grinding to of sample 3 face, first by AZ31 sample 3 with 502 gluings on the bottom surface of strip shape body 1, again ring bodies 2 is enclosed within outside strip shape body 1 and assembles, according to the thickness of laminar AZ31 magnesium alloy and grind requirement, if polish on abrasive paper for metallograph, can operate on sand paper by direct hand-held ring bodies 2 outer wall; If polish on mechanical polisher, while hand-holdable ring bodies 2 outer wall, apply pressure, to ensure that sample 3 can contact with polishing cloth all the time with a finger at strip shape body 1 end face; Have sample 3 due to glutinous on strip shape body 1 bottom surface, and inside and outside have individual difference in height, the bottom surface total energy keeping parallelism of strip shape body 1 and ring bodies 2, can ensure to grind the face come parallel with ring bodies 2 bottom surface like this; After having ground a direction, can rotate 90 ° to fixture and continue polishing, the cut that the direction before can eliminating to a certain extent produces, repeating this step just can by near for the impact of cut minimum.After sample 3 has been polished, according to the requirement of metallographic equipment, (1) sample 3 is retained on strip shape body 1 and directly carries out corroding rear observation, because strip shape body 1 is smooth cuboid, observes so be easy to be placed on sample 3 platform.(2) sample 3 carries out corrosion observation after departing from strip shape body 1, for some equipment, because of sample 3 space constraint, when can only place small sample 3, sample 3 after polishing and strip shape body 1 can be placed in acetone soln and soak half an hour to one hour, 502 glue can be allowed to come off completely, take out sample 3, then carry out the operations such as follow-up corrosion.
When carrying out transmission electron microscope observing, need all to polish to two faces of sample 3, first can carry out sample preparation by above-mentioned mode, then 502 glue are departed from acetone soln, again by the face end face of 502 gluings at strip shape body 1 of milled, use the same method another face of polishing, then departs from 502 glue with acetone soln.Two faces ground like this are all flat, are easy to follow-up transmission sample 3 and carry out the two spray of electrolysis or ion milling, then put into transmission electron microscope observing.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
