Technical field
The present invention relates to metal material research field, in particular to a kind of metallographic specimen clamping device.
Background technique
The preparation of metallographic specimen is the premise of microstructure observation's research.Currently, as metal material is in all trades and professions
The increasingly raising of demand, also more and more to the quantity of the detection of metallographic specimen progress, the shape of sample is also varied, due to
Different, clamping is difficult, so that preparation section is cumbersome and low efficiency, in order to improve the detection of sample metallographic working efficiency and
To more preferably microstructure observation's image, raising the efficiency and metallographic specimen quality of metallographic specimen need to be prepared as far as possible.
The preparation of metallographic specimen at present substantially uses three kinds of methods：1. directly holding sample on sand paper and polishing machine with hand
It carries out grinding and buffing, but this method is for small size sample, is easy the finger that frays in clamping process by hand, and due to
Finger force is uneven, it may appear that specimen surface handles unevenness phenomenon, the specimen surface matter after cannot ensure polishing, polishing
Amount, and to be easy the frictional force between polishing cloth excessive and fly out for sample during the grinding process, it is artificial to experimenter and periphery at
Injury.In addition to this, when manual polishing, polishing once can only one test specimen of single process, working efficiency is lower.2. to sample into
It is polished again after row damascene process, polishing treatment, but this kind of method operating process is complex, be easy to cause the wave of inlay
Take, and the solidification of inlay needs at least 12 hours time, processing efficiency is low.3. then using special fixture clamping sample
Sanding and polishing processing is carried out again, but existing clamp structure is complex at present, higher cost, and a kind of fixture is usually only fitted
For a kind of sample of specification, it is inconvenient to adjust, using being seriously restricted.Be badly in need of it is a kind of it is easy to operate, can easily be accommodated, guarantee to give birth to
Produce efficiency, low in cost, safe and reliable metallographic specimen clamping device.
Summary of the invention
The purpose of the present invention is to provide a kind of metallographic specimen clamping device, solve of the existing technology above-mentioned ask
Topic.The present invention can carry out firm clamping to multiple and various shapes metallographic specimens.
Above-mentioned purpose of the invention is achieved through the following technical solutions：

3, two through-hole set-up modes on lower fixture 4 are arranged symmetrically；Stud 1 corresponds to position on the upper fixture 3, lower fixture 4
Set the through-hole at place, the stud 1 is equipped with nut 2, the upper fixture 3, lower fixture 4 clamping face on opposite position set respectively
There is a semi-hexagon shape gap slot, the semi-hexagon shape gap slot is arranged between two through hole.
The upper fixture 3 is a cuboid almag plate, which is provided with two through-holes, and the through-hole is stud 1
It is inserted into location hole；The lower fixture 4 is equipped with two symmetrical through-holes identical with the lead to the hole site of upper fixture.
The stud 1 is hexagonal single head stud.
On the clamping face of the upper fixture 3, lower fixture 4, at least one semi-hexagon shape is respectively provided between two through hole
Gap slot, semi-hexagon shape gap slot correspond respectively, and the semi-hexagon shape notch slot structure at opposite position is identical.
The Cleat structures are " ten " font bulge-structure.
The beneficial effects of the present invention are：Novel, structure is simple, easy to operate, can easily be accommodated, low in cost, peace
It is complete reliable.It has saved and has ground the sample time, improved the safety of the working efficiency and experiment that prepare sample, reduce work people
The labor intensity of member guarantees production efficiency, practical.
