Description
Technical field
The utility model relates to a kind of clamping device, relates in particular to a kind of metallographic specimen clamping device.
Background technology
Metallographic test is the properties by the observe and decide metal material of macrostructure and microstructure, the accuracy of metallographic structure metallographic result depends on the preparation precision of the sample (hereinafter to be referred as metallographic specimen) that metal lographic examination uses to a great extent, therefore, the preparation of metallographic specimen is also just become the important topic of metallographic professional research.
Make metallographic specimen and further the sample of well cutting sanding and polishing need to be reached to mirror effect, at present, carry out metallographic test in school and business unit time, the sanding and polishing of metallographic specimen is that the hand-held sample of experimenter directly completes on sander substantially, the method of this hand-held sample need to be pointed firmly and clutch, and fastness is poor.Once insufficient clamping force, grinds in process sample and is easy to be ground power and gets rid of and dish out; In addition, in grinding process, also can cause damage to operating personnel's both hands, such as the wound such as broken skin, bubble is extremely general.
The fixture of the detection metallographic specimen of application now, although can meet the requirement of metal lographic examination, complex structure, and need both hands to operate simultaneously, use very inconvenient.
Summary of the invention
The utility model provide a kind of one-hand operation, easy to adjust, clamp firmly metallographic specimen clamping device, can improve conventional efficient, guarantee the security of experimentation, alleviate experimenter's labour intensity, avoid human injury.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of metallographic specimen clamping device, comprises in tune clamp and is distributed on clamp several long bolts and thread bush plug around in tune, in described tune, clamp top is concave inward structure, and balanced handle is established in bottom; Described thread bush plug has internal and external screw thread, is connected with clamp in tune by external screw thread, is connected with long bolt by internal thread.
In described tune, clamp material is aluminium alloy, and thread bush plug material is copper.
Described long bolt is full thread structure, and length is 20-150mm.
Described long bolt head is established end cap of the spring, and afterbody is established inner hexagonal hole, outer surface annular knurl.
Recess bottom surface level in clamp in described tune, and vertical with balanced handle axis.
In described tune, clamp top is square, along horizontal axis direction, 4 group leader's screw rods and thread bush plug is set.
Compared with prior art, the beneficial effects of the utility model are:
1) simple in structure, adjust easy to use, one-hand operation, improve conventional efficient;
2) can quick and convenient clamping sample, square and circular monomer sample or inlay sample and all can use;
3) clamping force is large, clamps firmly, guarantees the security of experimentation;
4) alleviate experimenter's labour intensity, avoid human injury.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 2, be structural representation of the present utility model, a kind of metallographic specimen clamping device of the utility model, comprises in tune clamp 3 and is distributed on clamp 3 several long bolts 1 and thread bush plug 2 around in tune, in described tune, clamp 3 tops are concave inward structure, and balanced handle 5 is established in bottom; Described thread bush plug 2 has internal and external screw thread, is connected with clamp 3 in tune by external screw thread, is connected with long bolt 1 by internal thread.
In described tune, clamp 3 materials are aluminium alloy, and thread bush plug 2 materials are copper.
Described long bolt 1 is full thread structure, and length is 20-150mm.
Described long bolt 1 head is established end cap of the spring 6, and afterbody is established inner hexagonal hole 8, outer surface annular knurl 7.
The interior recess of clamp 3 bottom surface 9 levels in described tune, and vertical with balanced handle 5 axis.
In described tune, clamp 3 tops are square, along horizontal axis direction, 4 group leader's screw rods 1 and thread bush plug 2 are set.
A kind of metallographic specimen clamping device of the utility model, in its tune, clamp 3 adopts aluminum alloy material, from heavy and light, is easy to machine-shaping; But its material is softer, be connected with long bolt 1 if directly offer screwed hole thereon, long bolt 1 is tightened repeatedly with loosening up can cause thread damage, therefore sets up copper thread bush plug 2.Thread bush plug 2 has inside and outside two external threading structures, and its external screw thread is connected with the screwed hole on clamp 3 in tune, after installation, need not frequently dismantle, and can not destroy the screwed hole on clamp 3 in tune; Its internal thread is used for installing long bolt 1, can meet the requirement of repeatedly tightening and unclamping.
In tune, clamp 3 tops have concave inward structure, and its bottom surface 9 is for placing sample 4 and making sample 4 bottoms vertical with balanced handle 5, facilitate sample 4 polishings to add man-hour experimenter and grasp grinding angle.In tune, clamp 3 can be made series specification, in the time of experiment, selects according to the size of sample 4.In tune, the balanced handle 5 of clamp 3 bottoms facilitates experimenter to hold with a firm grip, can make experimenter directly not contact sample simultaneously, ensures the accuracy of experiment.
Long bolt 1 is full thread, and head is with end cap of the spring 6, and several long bolts 1 coordinate to be tightened, and completes being fixedly clamped to metallographic specimen 4.The end cap of the spring 6 of head has played buffering and the effect of pressing, can be easily and fast, firmly metallographic specimen 4 is clamped, and can not cause damage to sample 4 surfaces.The afterbody of long bolt 1 is established inner hexagonal hole 8, can tighten sample 4 by inner hexagon spanner, and its surperficial setting tool has the annular knurl 7 of anti-skidding effect.
A kind of metallographic specimen clamping device of the utility model preferred version is that in tune, clamp 3 tops are square, along horizontal axis direction, 4 group leader's screw rods 1 and thread bush plug 2 are set.
When use, select suitable clamping device according to sample 4 sizes, sample 4 bottom surfaces are flat in the interior concave bottom surface 9 of clamp 3 in tune, one by one long bolt 1 is inwardly screwed, tighten one by one again after making sample 4 placed in the middle fixing.Grasp the balanced handle 5 of clamp 3 bottoms in tune, use sand paper or polishing machine sanding and polishing.
