Abstract
The utility model provides an assistant clamp for a tensile test of a material mechanics tester, belonging to the technical field of test. The assistant clamp is used for improving the accuracy of data of tensile test. The assistant clamp has the technical scheme that the assistant clamp consists of a clamp main body and a sample baffle board, wherein the clamp main body is cuboid and is fixed in a clamping opening of the material mechanics tester, the inner part of one side face of the clamp main body is provided with a straight clamping groove for containing the sample baffle board, the sample baffle board is arranged in the straight clamping groove of the clamp main body, the outline of the sample baffle board is matched with the inner space of the straight clamping groove, and the surface where the sample baffle board corresponds to a clamping opening of the straight clamping groove is provided with a sample limiting groove which is vertical to the straight clamping groove. The assistant clamp greatly improves the stability and the reliability for clamping small samples, creates a condition for obtaining exact test data, prevents the broken sample from flying out of the clamping opening of the material mechanics tester, and plays a role in safety protection.
Description
Technical field
The utility model relates to a kind of auxiliary clamp in order to the clamping sample that uses in the material mechanical test machine tension test, belong to technical field of measurement and test.
Background technology
Tension test is the most most important experiment in the material mechanical performance test, is one of method of widely used mensuration mechanical property on the engineering.Firmly, stably the clamping sample is a key of finishing tension test smoothly, but the folder mouth of current material mechanical test machine often can not obtain desirable clamping effect when the clamping small sample, in process of the test, sample is easy to generate the changing of the relative positions in the folder mouth, cause test figure inaccurate, and sample is more little, and error is big more.How to firmly fix small sample, prevent that it from producing the changing of the relative positions when stretching, and then obtain accurate test figure, be the difficult problem that the relevant technologies personnel are faced always.
In addition, when materials used mechanical test machine carried out tension test, the folder mouth of the material mechanical test machine that flies out easily after sample is broken brought threat for the personal safety of testing crew.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can be firmly, the material mechanical test machine tension test auxiliary clamp of clamping small sample stably.
The purpose of this utility model realizes with following technical proposals:
A kind of material mechanical test machine tension test auxiliary clamp, form by jig main body and sample block, described jig main body is a rectangular parallelepiped, be fixed in the folder mouth of material mechanical test machine, on an one inside, side, offer the straight clip slot that holds the sample block, described sample block is positioned at the straight clip slot of jig main body, and its gabarit is complementary with straight clip slot inner space, is provided with sample stopper slot perpendicular to straight clip slot in its corresponding one side of folder mouth with straight clip slot.
Above-mentioned material mechanical test machine tension test auxiliary clamp, described jig main body and sample block all are provided with two, the last Jia Kou of respective material mechanical test machine and folder mouth respectively down.
The utility model adopts the straight clip slot clamping sample head that is fixed on the material mechanical test machine folder mouthful interior jig main body, and utilize the sample stopper slot on the sample block to carry out spacing to the sample head perpendicular to straight clip slot, prevent the straight clip slot changing of the relative positions in sample chuck edge in process of the test, thereby improved the stability and the reliability of sample holder greatly, created condition for obtaining accurate test figure.Simultaneously, this auxiliary clamp also can prevent to fly out after sample from breaking folder mouth of material mechanical test machine has played the safeguard protection effect.

Embodiment
The utility model can be used in the material mechanics experiment chamber, when doing tiny sample tension test, these anchor clamps can be more firmly fixing sample, thereby obtain accurate test figure, and the folder mouth of the material mechanical test machine that can prevent to fly out after sample from breaking has played the security protection effect.
Referring to Fig. 1, Fig. 2, the folder mouth width of straight clip slot 5 prevents that less than the groove insied width sample head that is positioned at groove is drawn out, and also sample block 3 is played position-limiting action simultaneously.
Referring to Fig. 3, Fig. 4, the gabarit of sample block 3 is complementary with straight clip slot 5 inner spaces, can enter from straight clip slot 5 one ends, and slide along straight clip slot 5.
Referring to Fig. 5, Fig. 6, when the stretching small sample, earlier two jig main bodies 2 are sandwiched in upward pressing from both sides mouth 1 and pressing from both sides on the mouth 7 down of material mechanical test machine respectively, again the two ends of sample 4 are inserted respectively in the sample stopper slot 6 of sample block 3, then two sample blocks 3 are advanced respectively in the straight clip slot 5 of two jig main bodies 2, carry out tension test at last.Produce the changing of the relative positions in the time of can preventing to stretch small sample like this, and then obtain accurate test figure, prevent that simultaneously sample from because of splashing that fracture produces, having played safeguard protection.
