Description
Technical field
The present invention relates to micro Vickers field, in particular to prepared by the sample of a kind of micro-vickers hardness analysis
Device.
Background technique
Hardness range is wide, and measurement accuracy is high since it is measured for micro-vickers hardness, is widely used.But it is micro-
Vickers indentation is smaller, therefore also proposes very high requirement to the horizontality of specimen surface roughness and specimen surface, such as
It is explicitly pointed out in GB/T4340.1-2009 " Vickers Hardness Test of Metallic Materials first part: test method ", in plane impression
The difference of two catercorner lengths should be no more than the 5% of catercorner length average value.And when sample is measured out-of-flatness, measure impression
It can deform to more than 5%.Cause test result error larger, reduces the accuracy of test.
At present to guarantee that sample upper and lower surface is horizontal, general there are two types of methods:
1, sample upper and lower surface is tied, is placed on horizontal table.Manual grinding is easy mill tiltedly, and wire cutting can use up
Amount guarantees that sample upper and lower surface is parallel, but processing time consuming is laborious, while then helpless to some nonconducting samples.
2, using presently the most general flat-nose pliers.But flat-nose pliers can not clamp the irregular sample of shape (it is for example round,
Ellipse etc.), even if clamping by force, in later period test process, sample also can the run-off the straight in load engineering.
Chinese utility model patent CN 203949824U provides a kind of universal chuck of micro Vickers, principle
It is to pass through the intracorporal sample of location hole lock chamber using 4 positioning card feet.But it is big for base diameter, upper diameter is small
Cylindrical sample still can not fixation.
Summary of the invention
It is an object of the invention to overcome the drawbacks described above of the prior art, for the sample to be tested of irregular shape, provide
A kind of structure is simple, is equipped using the preparation that fast, easily micro-vickers hardness sample requires.
The present invention includes shell, the clamping element that can be clamped to centre is equipped in shell, one end of shell is equipped with can with shell
It is arranged to plane in conjunction with the face with isolated horizontal positioning element, the horizontal positioning element towards shell, shell is relative to horizontal location
The other end of part is equipped with mandril.
In use, sample to be tested to be placed on to the middle position of clamping element in shell, by horizontal positioning element in conjunction with shell
And by the plane of the tested surface of sample to be tested fitting horizontal positioning element, sample to sample to be tested movement and is pressed on water by mandril
In the plane of flat locating piece, by clamping element to centre clamp, at this moment sample to be tested be horizontally positioned part and mandril by perpendicular to
The direction in survey face clamps, and is clamped part and is clamped by the direction for being parallel to tested surface, then horizontal positioning element is separated with shell, this
When, the tested surface of sample to be tested just exposes in the top of shell, while sample to be tested is firmly clamped in shell, finally at
For the sample for meeting micro-vickers hardness sample requirement.
Detailed description of the invention
The particular content that the present invention is furture elucidated with reference to the accompanying drawings and embodiments.
Fig. 1: schematic structural view of the invention.
Fig. 2: Fig. 1 lateral view.
Fig. 3: the structural schematic diagram of another program of the present invention.
Fig. 4: Fig. 3 lateral view.
Specific embodiment
As shown, the present embodiment includes shell 1, it is equipped with the clamping element 2 that can be clamped to centre in shell 1, the one of shell 1
End is equipped with the horizontal positioning element 3 combinable and isolated with shell 1, and the face of horizontal positioning element 3 towards the shell 1 is arranged to plane,
Shell 1 is equipped with mandril 4 relative to the other end of horizontal positioning element 3.
The shell 1 uses bolt-connection, its court after the horizontal positioning element 3 couples with shell 1 with horizontal positioning element 3
Face into shell 1 is the plane of finishing, outer surface of the shell 1 relative to the shell 1 of the other end of the horizontal positioning element 3
A plane can be defined, the plane defined by the outer surface at the end is parallel with the precision-machined surface of horizontal positioning element 3.In this way, shell
The plane that 1 outer surface of body defines can be placed on workbench, and the tested surface of sample to be tested can keep parallel with workbench
State.
The clamping element 2 is two and sets up relatively, is coupled between each other by bolt 25 mutual to realize
Folding.The opposite direction of clamping element 2 is equipped with the notch 21 of recess, increases the contact point with sample to be tested with this, so that clamping element 2
It is more stable to the clamping of sample to be tested.In order to adapt to the sample to be tested of different size size, several notches 21 can be set
The different clamping element 2 of size be replaced.Elastic piece 22 is arranged in the clamping element 2 at notch 21, elastic in this way
Piece 22 can be deformed to a certain extent according to the shape of sample to be tested and be coated to sample to be tested, increased with this and more connect
Contact.Described 22 one end of elastic piece is fixed on the other end on clamping element 2 and slides in notch 21.The clamping element 2 can be with
It is one of fixation, another is removable, is also possible to both move.It is arranged to moveable clamping element 2 and shell
It is equipped with slide block guide rail pair between body 1, guarantees that clamping element will not change in upright position with this.
It is threaded between the mandril 4 and shell 1.For the sample to be tested for needing bottom to support, in sample
Need to retain the mandril after the completion of preparation.Since the shell coupled with mandril is located at the position of the relative direction of horizontal positioning element,
In order to not influence the plane that the outer surface of direction shell defines, the position that shell couples with mandril needs to be recessed to enclosure interior
Certain size, so that mandril will not expose the housing outer surface in the direction.For not needing the sample to be tested of bottom support,
It can not have to retain mandril after the completion of sample preparation.
