Abstract
The utility model discloses a sample support device for a stretching test, which comprises a sample support. A sample clamp is arranged on the sample support, two ends of the clamp are provided with a spiral clip respectively; the two spiral clips are respectively clamped at two ends of a sample to be tested, and at least one spiral clip can rotate. Compared with the prior art, the sample support device has the following advantages: as the sample clamp is added, the sample is arranged on a support and aligned with a notch, after the whole sample is in level, the two spiral clips can fix and stabilize the sample, testing staff can accurately measure the diameter and the vernier distance after fracture by using a micrometer or a vernier caliper. By adopting the sample support device for the stretching test, the measurement can eliminate influences of human factors on measurement data of the sample after the fracture, and greatly improve accuracy; besides, the cost for manufacturing the support is low, the operation is convenient and simple, and the repeatability is good.
Description
Technical field
The utility model relates to the material mechanical performance field tests, particularly a kind of tension test sample holder device.
Background technology
Tension test is one of the most common test method in the material mechanical performance test.Each stage such as the elastic deformation in the test, plastic yield, fracture has truly been reflected the overall process of material opposing external force effect.The resulting strength of materials of tension test and plastic property data all have very important use value and reference value for design and selection, the development of new material, buying and examination, the quality control of product and the safety and the assessment of equipment of material.The reviewer measure the stretching sample have no progeny diameter and gauge length time, can only lean on manual two sections that a sample is disconnected of operating personnel, according to the crops for rotation alignment of fracture, and then measure the length (being accurate to 0.1 millimeter) of its have no progeny diameter and the gauge length of having no progeny.Its defective is: because different personnel's operation firmly varies in size, finally cause the repeatability of many people measurement result bad, cause the unnecessary measuring error of data.
For addressing the above problem, people make the support of the stretching sample that a support has no progeny, sample is lain in above the support, and then with the measurement of have no progeny after the section alignment diameter and gauge length.But so still there is certain drawback, though promptly solved the not exclusively manually method of fixed sample, but the balance fracture that coincide because the two ends sample can not be subjected to the effect of bed knife in the time of still can not guaranteeing different personnel operation, makes the error of measurement data reduce to minimum.
The utility model content
Technical problem to be solved in the utility model is, at above-mentioned prior art present situation, and provide a kind of error of measurement data little, the good tension test of the repeatability sample holder device of measurement result.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of tension test sample holder device, comprise sample holder, it is characterized in that: described sample holder is provided with sample anchor clamps, described anchor clamps two ends respectively are provided with the spiral clamp, and described two spiral clamps can be stuck in the two ends of sample to be tested.
At least one is rotatable for described two spiral clamps.
Compared with prior art, advantage of the present utility model is, because increased sample clamp, sample is placed on the support good fracture, and after making whole sample levels, two spiral clamps can be fixed sample and stable, and the test personnel just can accurately measure have no progeny diameter and gauge length with milscale and vernier caliper.Utilize the utility model to measure, making stretches, and the sample measurement data of having no progeny have been eliminated artificial factor, and its accuracy improves greatly, and it is low to make the cost of this support, easy to operate simple, good reproducibility.
