Abstract
The utility model discloses a bolt tensile test tool. The bolt tensile test tool comprises an upper fixture and a lower fixture corresponding to the upper fixture; the lower part of the upper fixture is provided with a connection sleeve; the bottom of the connection sleeve is provided with a through hole adaptive to a bolt screw; the lower fixture is provided with a threaded hole which corresponds to the through hole and is matched with the bolt screw section; the screw part of the bolt passes through the through hole formed in the connection sleeve and is matched with the threaded hole of the lower fixture; the head part of the bolt is fixed on the upper fixture by the connection sleeve; the upper fixture and the lower fixture are respectively fixed in upper and lower jaws of a tester to perform a tensile test on the bolt to measure the tensile strength of the bolt accurately and prevent errors caused by inaccurate conversion; the through hole in the connection sleeve can be manufactured according to the size of the bolt; the threaded hole in the lower fixture also can be manufactured according to the size of the bolt and is high in universality. The bolt tensile test tool provided by the utility model is compact in structure, accurate in measurement result and is simple to use.
Description
Technical field
The utility model relates to a kind of bolt tension test tool.
Background technology
Tension test refers to is bearing under axial tension load, measures the test method of material behavior, utilizes data that tension test obtains can determine tensile strength, yield strength, length growth rate, shrinkage factor and other tensile property index of material.Because the tension test of bolt is difficult to realize, in the situation that there is no auxiliary mould, generally it is carried out to hardness detection, then be converted into tensile strength, because hardness detects the several points that only detect surface, be difficult to react truly the quality condition on the whole cross section of bolt, it is unilateral becoming tensile strength with hardness conversion, and limitation is large, and the uncertainty of its result increases, representativeness is poor, is difficult to react the actual strength of bolt.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, a kind of compact conformation is provided, has measured accurate bolt tension test tool.
In order to solve the problems of the technologies described above, design feature of the present utility model is: comprise fixture and the lower clamp corresponding with upper fixture, the bottom of described upper fixture is provided with adapter sleeve, the bottom of described adapter sleeve is provided with the through hole adapting to bolt screw rod, and described lower clamp is provided with threaded hole corresponding with through hole and that coordinate with bolt spiro rod section.
Described adapter sleeve comprises circular connector, and an end of connector seals by diapire, and the other end opens wide, and described through hole is arranged on diapire.
Distance between the lower surface of described upper fixture and adapter sleeve bottom is more than or equal to the thickness of bolt head.
Outside surface one end of described upper fixture is provided with external thread, and the inside surface of described adapter sleeve is provided with corresponding with the external thread of upper fixture and adapter sleeve can be installed to the internal thread on upper fixture.
Compared with prior art the utlity model has following advantage: the threaded shank of bolt coordinates with the threaded hole of lower clamp through the through hole on adapter sleeve, bolt head is fixed on upper fixture by adapter sleeve, respectively upper lower clamp is fixed in the bit of testing machine, bolt is carried out to tension test, its tensile strength of Measurement accuracy, the inaccurate error causing of avoiding converting; Through hole on adapter sleeve can be made according to bolt size, and the threaded hole on lower clamp also can be made according to bolt size, highly versatile, and the utility model compact conformation, measures accurately, and uses simple.
