Utility model content
This utility model relates to a kind of fixture for high elongation rate testing of materials, and solving fixture present in prior art can not the problem of Validity Test high elongation rate material.
For solving above technical problem, the technical scheme that this utility model provides is as follows: a kind of fixture for high elongation rate testing of materials, including adapter, two to upper lever beam, two downward lever beams, spring guide, spring, horizontal lever beam, two bite limited blocks, be arranged on the both sides of adapter to upper lever beam and downward lever beam；Two one end to upper lever beam are hinged with adapter respectively, two other ends to upper lever beam are respectively articulated with one end of two downward lever beams, the most hinged horizontal lever beam of the other end of two downward lever beams, forms six pin joints altogether, and six pin joints are in the same surfaces of revolution；It is respectively fixedly connected with bite limited block in the end of the other end of two downward lever beams；It is connected between adapter with horizontal lever beam and has spring, at spring center, be provided with spring guide；The movement of adapter pulls and clamps and loosening up to upper lever beam, the motion of downward lever beam and then two bite stops of control.
Adapter is provided with pin-and-hole, pin-and-hole connecting pins.
Further, the opposite face of described bite limited block is respectively provided with tooth engaged, forms two-sided staggered occlusion, and single tooth engaged uses 4 rhombus designs for processing is convenient, and the height of each tooth is 2mm.
Further, the height of described bite limited block is less than 1 type dumbbell shape sample tip lengths 5mm of the GBT528-2009 regulation of national regulations, during clamping, bite is stretched in sample upper end, and the gap between described horizontal lever beam and two bite limited blocks be enough to accommodate the sample stretched out.
Further, described spring guide uses air cylinder structure, provides the sufficiently strong chucking power being perpendicular to sample when sample stretches for spring.
Further, the material of described fixture is 304 rustless steels.
This fixture for high elongation rate testing of materials that this utility model relates to, has the beneficial effect that:
The most effectively solve and occur in that in fields such as PVC, PE a lot of quality is soft, the clamping problem occurred when percentage elongation is more than the testing of materials of the high elongation rate of 1000%.
2. reasonable due to design science of the present utility model, this type of fixture can also be used for soft, the fixed network of material.Expand range of the present utility model further.
3. this utility model has novel structure, processes the advantages such as easy, esy to use, safe and reliable.There is positive social benefit and significant use value.
