Abstract
A kind of pole type sample hardness test harness, belong to technical field of measurement and test, for expanding the test specification of hardness testing device, its technical scheme is, it comprises style holder, described style holder is positioned on the test platform of hardness testing device, and its upper surface is provided with two orthogonal V-type grooves, places pole type sample to be tested in a V-type groove wherein.The utility model is provided with two V-type grooves for fixing pole type sample, can select arbitrarily, so just expand the test specification of hardness testing device according to the concrete size of tested pole type sample.When using this harness to carry out hardness test, do not need to carry out machine work to the test surfaces of sample, saved processing cost.The test platform that this harness directly can be placed on hardness testing device uses, only needs mobile style holder in test process, do not need repeatedly to load and unload sample, the saving test duration.
Description
Technical field
The utility model relates to and a kind ofly to use when measuring material hardness, for carrying and the harness of fixing pole type sample, belongs to technical field of measurement and test.
Background technology
Hardness is the important parameter that opposing hard object in exosyndrome material local is pressed into its surface energy, can probably judge the performances such as the tensile strength of material by hardness test.
At present, pole type sample testing platform is the brace table with single deep Vee hull groove, lifting screw by screw thread and hardness testing device fixes, brace table itself cannot move, and mobile sample can only be leaned on during test to carry out hardness determination, and its shortcoming existed only to test the pole type sample of certain diameter, test specification has certain limitation, and style less stable, easily rotate in test process or twist, cannot measuring accuracy be ensured.Therefore, how to expand the test specification of hardness testing device and ensure the measuring accuracy of pole type sample, just becoming the problem that relevant technologies personnel face.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of pole type sample hardness test harness that can adapt to various sample, to expand the test specification of hardness testing device.
Problem described in the utility model realizes with following technical proposals:
A kind of pole type sample hardness test harness, formation comprises style holder, described style holder is positioned on the test platform of hardness testing device, and its upper surface is provided with two orthogonal V-type grooves, places pole type sample to be tested in a V-type groove wherein.
Above-mentioned pole type sample hardness test harness, also comprise at least two pieces of style pressing plates in formation, one end of every block style pressing plate is bolted on style holder, and the other end is pressed on pole type sample to be tested.
Above-mentioned pole type sample hardness test harness, the degree of depth of two V-type grooves on described style holder and/or cell wall inclination angle difference.
The beneficial effects of the utility model are:
(1) the utility model is provided with two V-type grooves for fixing pole type sample, can select arbitrarily, so just expand the test specification of hardness testing device according to the concrete size of tested pole type sample.
(2) style pressing plate is for compressing pole type sample, prevents sample from rotating in test process or twisting, thus improves the measuring accuracy of sample hardness.
(3), when using this harness to carry out hardness test, only the test surfaces of sample need be carried out polishing according to hardness test concerned countries standard-required, not need to carry out machine work again, saved processing cost.
(4) test platform that this harness directly can be placed on hardness testing device uses, only needs mobile style holder in test process, do not need repeatedly to load and unload sample, the saving test duration.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the state of the utility model when filling large pole sample;
Fig. 2 is the state of the utility model when filling little pole sample.
In figure, mark is as follows: 1, style holder; 2, style pressing plate; 3, bolt; 4, large V-type groove; 5, little V-type groove; 6, pole type sample.
Embodiment
Referring to Fig. 1 and Fig. 2, this pole type sample hardness test harness comprise be with the square shaped version holder 1 of double V-shaped groove, one end forms with the style pressing plate 2 of bolt hole and bolt 3.Style holder 1 is made up of corrosion resistant plate, and style pressing plate 2 is made up of the sheet steel of stainless steel.Style pressing plate 2 is connected with style holder 1 by bolt 3, and pole type sample 6 is fixed by the style pressing plate 2 of both sides, prevents sample from rotating in test process, ensures the accuracy of test result.
Concrete operations of the present utility model are as follows:
First lain in a horizontal plane in the suitable V-type groove on style holder 1 (as shown in Figure 1 and Figure 2) according to the size of pole type sample 6, with the style pressing plate 2 of V-type groove both sides, pole type sample 6 is compressed again, then style holder 1 is placed on the test platform of hardness testing device, carry out hardness test, can be moved around in test process style holder 1 as required, thus record multiple hardness number.
Claims (3)
1. a pole type sample hardness test harness, it is characterized in that, it comprises style holder (1), described style holder (1) is positioned on the test platform of hardness testing device, its upper surface is provided with two orthogonal V-type grooves, places pole type sample (6) to be tested in a V-type groove wherein.
2. a kind of pole type sample hardness test harness according to claim 1, it is characterized in that, at least two pieces of style pressing plates (2) are also comprised in formation, one end of every block style pressing plate (2) is fixed on style holder (1) by bolt (3), and the other end is pressed on pole type sample (6) to be tested.
3. a kind of pole type sample hardness test harness according to claim 1 and 2, is characterized in that, the degree of depth of two V-type grooves on described style holder (1) and/or cell wall inclination angle difference.
