Abstract
The utility model discloses an anchor clamps for lamellar metallographic specimen, including two at least columniform gaskets, gasket edge is equipped with a screw hole, and two upper and lower gaskets are connected as an organic wholely by screw through fixed, has seted up a rectangular logical groove in the middle of the gasket on the terminal surface the long limit direction of leading to groove one side is equipped with the cotter hole. The utility model has the advantages of simple structure to through the screw, can make lower floor's gasket use the screw to vary the gasket wantonly as the center and in the relativity shift angle of horizontal direction, grind with the metallographic specimen that is fit for various specifications size.
Description
Technical field
The utility model relates to medal polish grinding class fixture, is specifically related to a kind of fixture for laminar metallographic specimen.
Background technology
Metallographic structure is the concrete form of reflection metal metallographic, as martensite, and austenite, ferrite, pearlite etc.; The metallographic structure of broad sense refers to the admixture of two or more material under microstate and interaction situation.
Grinding of metallographic specimen is a most important procedure in metallographic sample preparation operation, it is grind sample sand paper from coarse to fine by hand that conventional metallographic specimen grinds operation, the shortcoming of this traditional grinding method is easy bevelling, for some decarburized layer samples and other samples laminar not too applicable.At present, sample is inlayed and mainly adopts pointing machine, but still cannot fix for laminar metallographic specimen, laminar metallographic specimen is not easily upright, and grinding in process, needing firm fixing sample, avoid it to move, and usually need to grind several sample grinding in process, if install one by one, grind, dismantle and relatively lose time simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, be easy to installing/dismounting sample and conveniently grind the fixture for laminar metallographic specimen of sample.
The purpose of this utility model is achieved through the following technical solutions: a kind of fixture for laminar metallographic specimen, comprise at least two columniform pads, described gasket edge place is provided with a screwed hole, upper and lower two pads are run through by screw and are connected to one, in the middle of pad, end face offers a rectangular groove, be provided with pin hole at the long side direction of described groove side.
In order to better realize the utility model, further, described each pad is respectively provided with two pin holes, and pin hole is arranged perpendicular to groove.
In order to better realize the utility model, further, be provided with the pin of aperture adaptation with it in described pin hole, pin length is greater than pin hole length and groove width sum.
In order to better realize the utility model, further, the bottom surface of described pin is provided with adhesive.
In order to better realize the utility model, further, described groove one end is blind end, and the other end is through the circular arc end face of pad.
The utility model has the following advantages and beneficial effect:
(1), the utility model structure is very simple, by offering the groove of semiclosed opening, not only can facilitate installing/dismounting metallographic specimen, is also convenient to the observation in process.
(2), the utility model can be applicable to the metallographic specimen processing of sizes size, can vertically, horizontal positioned and can also simultaneously inlay several metallographic specimen according to the quantity of pad.
(3), the utility model for the metallographic specimen of large-size a little, corner can be carried out by four pins to it and hold fixing, and be provided with adhesive bottom pin, wearing and tearing can not be produced to metallographic specimen.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Embodiment 1
As depicted in figs. 1 and 2, a kind of fixture for laminar metallographic specimen, comprises at least two columniform pads 2, and wherein, the shape of pad 2 is not limited to cylindrical, and namely the shape such as regular polygon, cuboid can; Described pad 2 edge is provided with a screwed hole, and upper and lower pad 2 is run through by screw 4 and is connected to one, and the middle end face of pad 2 offers a rectangular groove 1, is provided with pin hole at the long side direction of described groove 1 side; Wherein, groove 1 one end is blind end, and the other end is through the circular arc end face of pad 2, and such structure is also beneficial in the process of grinding and observes sample in real time.
Embodiment 2
The threaded engagement utilized can make the pad 2 on upper strata be fixed on above underlying shims 2 and not contact, i.e. state as shown in Figure 1; The deviation angle of pad 2 horizontal direction can be adjusted arbitrarily like this, thus according to the specification of metallographic specimen or need choice for use pad 2 still at least two pads 2 when grinding; And, upper strata pad 2 can also overlap with underlying shims 2 by being rotated down, i.e. state as shown in Figure 3 and Figure 4, such benefit is that this fixture can be applicable to grinding the metallographic specimen of different size size, two the pad 2 level clamping metallographic specimens also overlapped by dislocation grind, and state as shown in Figure 3, is placed on the horizontal surface of underlying shims 2 by metallographic specimen, upper strata pad 2 direction of rotation is fitted with underlying shims 2, then can to grind the horizontal plane of metallographic specimen.
Embodiment 3
Described each pad 2 is respectively provided with two pin holes, and pin hole is arranged perpendicular to groove 1; The pin 3 that aperture is consistent is with it provided with in pin hole, when the size of sample is larger, can be overlapped upper lower gasket 2 placement completely, and fix with four pins 3, pin 3 is consistent with pin hole aperture, be convenient to pin 3 fix metallographic specimen and fix comparatively firm, metallographic specimen is grinding not easily slightly movement in process; Pin 3 length is greater than pin hole length and groove 1 width sum, and the bottom surface of pin 3 is also provided with adhesive, and adhesive can avoid pin 3 and sample contacts, makes that sample is unlikely to be damaged; The pin 3 being stained with adhesive is used for holding fixing metallographic specimen, on the inwall being close to groove 1 enabling metallographic specimen smooth, ensure that pin 3 length is greater than pin hole and groove 1 width sum, can with groove 1 contact internal walls away from pin hole side after mainly making the bottom of pin 3 pass pin hole, namely pin 3 has sufficient length to be held by metallographic specimen on groove 1 inwall.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model, every according to the utility model to above embodiment make any embodiment without the need to arriving through creative work, all belong within protection domain of the present utility model.
