Abstract
Chuck is fixed on bolt group after a kind of total cross-section flexible material tension test fixture, gland clamping compliant specimens, sample is close to jaw face around 90 °, enables the center line of sample parallel with fixture main shaft again；Chuck locating shaft is put into the eccentric locating slot on clamp body, adjustment axle and locating slot gap, it is ensured that the center line of sample and fixture main shaft line overlap, tightening nut fix chuck with clamp body, are tested after being connected with the connecting hole on clamp body with testing machine., can be because clamping process reduces section when being clamped to total cross-section flexible material during tension test, retained part resistance stretch capability declines, and causes material to be broken in retained part；Using after this fixture, active force is that the frictional force that is produced by retained part is adjacent to the frictional force sum produced during chuck with material and is applied to testing of materials part, it is much smaller than retained part stress and is applied to testing of materials part stress, it ensure that material is broken in part of detecting, obtain accurate test data.
Description
Technical field
The invention belongs to measure quality inspection, rubber plastic, iron and steel metallurgy, machine-building, electronic apparatus, automobile production, textile chemical fiber, electric wire, packaging material and food, instrument and meter, medicine equipment, civilian nuclear energy, civil aviation, institution of higher learning, scientific experiment institute, commodity inspection is arbitrated, technical supervision department, building materials ceramics, the technical field of the performance detection of the industries such as petrochemical industry, more particularly to a kind of application stretches the performance test to metal and nonmetallic materials, such as rubber, plastics, plastic cement, film, weaving, fiber, nano material, high polymer material, composite, strap, paper, electric wire, optical fiber cable, safety belt, safety belt, leather belt, footwear, adhesive tape, polymer, steel pipe, copper material, section bar, spring steel, bearing steel, stainless steel（And other glass hard steels）, casting, steel plate, steel band, non-ferrous metal, auto parts and components, the fixture that tension test is carried out in the case of alloy material and other nonmetallic materials and metal material total cross-section and flexible material.
Background technology
During research and probe new material, new technology, new technology and new construction, the performance detection of material is a kind of indispensable important test content.In drawing process, testing machine should possess appropriate fixture, i.e.,：Fixture should not cause sample and is broken at fixture, when applying any load, and the fixture on testing machine should be able to be directed at into a line immediately, so that the major axis of sample is overlapped with the draw direction by clamp central line.In process of the test, the experimental condition of sample according to《The measure of plastic tensile performance（Third portion：The experimental condition of film and thin slice）》（GB/T1040.3-2006）Etc. standard, such as film, thin slice and wire rod total cross-section flexible material are difficult to measure accurate data with routine test machine standard configuration fixture.The fixture of linear material is installed at present because retained part is long, the mechanical property for material in short supply is unfavorable, so, it is restricted in use.
The content of the invention
The technical problem to be solved in the present invention is：During application fixture carries out Mechanics Performance Testing, certain strength is produced using hold-down mechanism frictionally, the frictional force that flexible material abuts in jaw face generation is added, is stably installed material.Neither because making material deformation effect performance test in compaction process, measured material is can guarantee that again when applying any load, the fixture on testing machine can be directed at into a line immediately, so that the major axis of sample is overlapped with the draw direction by clamp central line.
Technical scheme
A kind of total cross-section flexible material tension test fixture, it is characterized in that：Having on chuck 4 has screw thread 8 on two chuck locating shafts 1, chuck locating shaft 1, be fixed on chuck 4 with two bolt groups 9 after the clamping compliant specimens 3 of gland 2, compliant specimens 3 clamped with frictional force, compliant specimens 3 are close to the surface of chuck 4 around 90 °；There are the specific locating slot 5 of two cam locks and a connecting hole 10 on clamp body 11；Chuck locating shaft 1 is put into the specific locating slot 5 of cam lock, plain cushion 6 is covered at screw thread 8, nut 7 is screwed on again, adjust chuck locating shaft 1 and the specific gap of locating slot 5 of cam lock, ensure that the center line of compliant specimens 3 is overlapping with the axis of connecting hole 10, chuck locating shaft 1, is locked by tightening nut 7 with frictional force with clamp body 11, is connected with connecting hole 10 with testing machine.
Advantages of the present invention and beneficial effect are：
1. the present invention is one simple in construction, it is easy to the fixture of operation.
2. the present invention is during tension test, when being clamped to total cross-section flexible material, can be because clamping process reduces section, after force, retained part resistance stretch capability declines, and causes material to be broken in retained part, and the phenomenon of influence test effect is produced；Using after this fixture, active force is that the frictional force that is produced by retained part is adjacent to the frictional force sum produced during chuck with material and is applied to testing of materials part, the pulling force for producing retained part, which is much smaller than, is applied to testing of materials part pulling force, it ensure that material is broken in part of detecting, obtain accurate test data.
