Technical field
The present invention relates to the aid and its application method of a kind of hardness tester verification, for using standard block of hardness to hard
Spend the daily verification that equipment is carried out.
Background technology
Hardness test is carried out to determine material hardness whether to meet the value of engineering drawing or specification defined, its
Purpose is by determining that the hardness number of standard known to surveying hardness number meets confirms technological effect of the material through processing.
Hardness test requirement, before experiment is started daily, or after replacing load and replaceable pressure head, it will be verified.Adopt
With standard block of hardness, scale used is examined and determine, to each daily standard verification test block, at least carries out hardness survey twice
Examination, experiment should be uniformly distributed on the experiment face of calibrated bolck, and the edge of any impression centre distance mark block is at least 2.5 times of pressure
Trace diameter, adjacent indentations centre-to-centre spacing are at least 3 times of impression diameter.
Due to checkpoint randomness this can bring following problem：
1）Reviewer estimates impression point distance and carries out effect, and impression spacing is easy to be excessively near and turns into invalid impression point；Between impression
Away from excessive, the service efficiency of block of hardness is low to be caused to waste.
2）Reviewer will take a long time searching and close when having progress effect on the calibrated bolck of impression point
Suitable position is verified, and can be brought inconvenience to operator, is substantially increased the operation difficulty of user, is influenceed operating efficiency.
The content of the invention
The technical problem to be solved in the present invention is to provide the aid and its application method of a kind of hardness tester verification, this is auxiliary
Assistant engineer has energy fast positioning impression point position, while ensures that the block of hardness can be fully utilized, and ensures the maximum of impression quantity
Change, improve operating efficiency.
To solve problem above, concrete technical scheme of the invention is as follows：A kind of aid of hardness tester verification, with
The outer of hardness standard block diameter identical disk is provided with semicircle set, and semicircle set is on 1/2 excircle of disk；In disk
Center is provided with central through hole, and the diameter d of central through hole, and open slot is provided with disk, and open slot is the radial direction of disk
And connected with central through hole；Several auxiliary tanks are provided with the side of open slot, the terminal of auxiliary tank is positioning through hole, and positioning is logical

Heart cylinder axis is parallel；
2）Disk is placed in the upper surface of hardness standard block, and ensures that semicircle set is bonded with calibrated bolck excircle；
3）Hardness standard block uses first：The central through hole of disk is the center of circle of hardness standard block, and pressure head passes from pressure head hole,
Pressure head is set to apply impression point at central through hole；
4）Hardness standard block is non-to be used first：Repeat step 2）, and determine that the impression point at center overlaps with the central through hole of disk；
4.1）Used first on certain Radius circle：Used first on certain Radius circle：When this is in the impression track of same Radius
On when there is no impression point, concave groove mark and the positioning line position pair of disk upper surface respective radius that hardness compressing head is put
Should, hardness compressing head set is moved downward, and checkpoint is got with the position of the position line compareed in open slot；
4.2）Certain Radius circle is above non-to be used first：When this is in existing impression point on the impression track of same Radius, rotate
Disk, by the positioning through hole in a certain impression alignment disk in this radius, while in the radius at corresponding open slot without pressure
Trace, the concave groove mark and the position line position correspondence of the respective radius of disk upper surface that hardness compressing head is put, hardness tester pressure
Headgear is moved downward, and checkpoint is got with the position of the position line compareed in open slot.
The aid of hardness tester verification is fully positioned using disk and semicircle nested structure with hardness standard block, and is passed through
The relative position relation of open slot and positioning through hole, ensure the distance between each two impression point, that is, ensure that suppressing for impression
Efficiency, and ensure that each impression point is effective impression point, so as to improve verification efficiency.
The opening direction of open slot is with the position where semicircle set on the contrary, being on the one hand easy to the processing of disk, on the other hand
It is easy under special circumstances, when pressure head can not rise, pressure head is departed from by open slot and disk.
The positioning through hole of outermost end and the distance of disk border are 2.5d, and the impression point for ensureing edge is also effectively verification
Point.
Using the application method of the aid of the application, mark effectively can sufficiently be utilized with fast positioning impression point
Block of hardness, each impression point on mark block of hardness is set not waste.
