Abstract
The utility model discloses a kind of sample clamping device of tension tester, it comprises symmetrically arranged two jaws, two jaw pins, two jaw plates, also comprise two ends and be symmetrical arranged sample in inverted L shape and symmetrically arranged two fixed blocks, every described fixed block has an arc surface, and the arc surface of described sample and every described fixed block is bonded to each other.The utility model reasonable in design, can overcome thinner sample at jaw by the defect crushed, improve tensile strength, thus ensure that the accuracy of test result, and respond well.
Description
Technical field
The utility model relates to tension tester field, is specifically related to a kind of sample clamping device of tension tester.
Background technology
Tension tester is commonly used to the tensile strength of test sample.But in the sample testing of thinner specification, usually break at jaw place, as shown in Figure 1, Fig. 1 is the sample clamping device of traditional tension tester, it sample 3 comprising jaw 1, jaw pin 2 and be placed between jaw 1 and jaw pin 2, sample 3 linearly type, sample two ends are directly clipped in jaw and carry out tensile test, sample is in continuous tension process, and with the continuous increase of pulling force, friction force also constantly increases, need normal pressure also corresponding increase, cause thinner specimen surface to be crushed in jaw, reduce tensile strength, cause sample to be broken in jaw.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of sample clamping device of tension tester, its object: ensure that specimen surface is not crushed distortion as far as possible, improve tensile strength.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of sample clamping device of tension tester, it comprises symmetrically arranged two jaws, two jaw pins, two jaw plates, also comprise two ends and be symmetrical arranged sample in inverted L shape and symmetrically arranged two fixed blocks, every described fixed block has an arc surface, and the arc surface of described sample and every described fixed block is bonded to each other.
Preferably, every described jaw plate is provided with a groove, and described groove is used for accommodating described sample.
Pass through technique scheme, the beneficial effects of the utility model are: the utility model have employed the fixed block with arc surface and the sample in inverted L shape, the friction force of sample at jaw place is reduced, namely the normal pressure of jaw to sample is reduced, such sample can not be crushed at jaw surfaces, thus overcome the defect that sample is pulled off, ensure that the accuracy of test result.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the sample clamping device of traditional tension tester;
Fig. 2 is the sample clamping device schematic diagram of a kind of tension tester disclosed in the utility model embodiment 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
Embodiment 1.
As shown in Figure 2, a kind of sample clamping device of tension tester, it comprises symmetrically arranged two jaws 4, two jaw pins 5, two jaw plates 6, also comprise two ends and be symmetrical arranged sample 7 in inverted L shape and symmetrically arranged two fixed blocks 8, every described fixed block 8 has an arc surface, and described sample 7 is bonded to each other with the arc surface of every described fixed block 8.Its advantage makes sample after bit clamping, walk around an arc surface and be tightened up, and reduce the normal pressure of jaw to sample, sample would not be crushed at jaw surfaces, thus ensure that the accuracy of test result.
Continue as shown in Figure 2, every described jaw plate 6 is provided with a groove, and described groove is used for accommodating described sample 7.
From the above sample clamping device adopting a kind of tension tester of the present utility model, reduce the normal pressure of jaw to sample, such sample would not be crushed distortion at jaw surfaces, thus ensure that the accuracy of test result, and respond well.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. the sample clamping device of a tension tester, it comprises symmetrically arranged two jaws, two jaw pins, two jaw plates, it is characterized in that, also comprise two ends and be symmetrical arranged sample in inverted L shape and symmetrically arranged two fixed blocks, every described fixed block has an arc surface, and the arc surface of described sample and every described fixed block is bonded to each other.
2. the sample clamping device of a kind of tension tester according to claim 1, is characterized in that, every described jaw plate is provided with a groove, and described groove is used for accommodating described sample.
