The chuck device can be applicable to the tensile test of the thin film material.
Description
Technical field
The invention belongs to the tension test of clamping membraneous material technical field, particularly a kind of membraneous material tensile testing jaws device.
Background technology
Along with the development of modern science and technology, various membraneous material is widely used.The mechanical property research of membraneous material is a current large focus.Tension test is the most basic test of research material mechanical property, carries out stretching research to membraneous material, considers that the most basic problem is exactly the clamping of film test piece.
What usual cupping machine was equipped with is wedge shape stretching clamp, its ultimate principle is by alignment jig removes handle, clamp body is impelled to rise or to decline, spacing between adjusting wedge, adapt to different plates specimen thickness, but this type of fixture all exists minimum grip thickness when designing, the material being less than this thickness cannot be tested by clamping, solution was at the bonding block that thickens in test film two ends to increase bare terminal end thickness in the past, to reach the requirement of minimum grip thickness.But above-mentioned solution exists certain defect, on the one hand, adopt the bonding mode thickening block to prepare test specimen efficiency not high, when carrying out many group tension tests, need bonding many groups; On the other hand, bonded adhesives may have an impact to the mechanical property of membraneous material root bonding with thickening block, causes the final material mechanical performance obtained to have deviation.Therefore, need design one not have an impact to material mechanical performance, clamping thickness can change to certain thickness specific chuck by zero simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of membraneous material tensile testing jaws device that can be applicable to membraneous material tension test.
The technical solution realizing the object of the invention is:
A kind of membraneous material tensile testing jaws device, comprise fixed flat planar part, mobile flat part, sliding guide and drive screw, fixed flat planar part one end has testing machine assembling pin-and-hole, fixed flat planar part is fixed with sliding guide, sliding guide is through the through hole in mobile flat part, and drive screw is threaded with mobile flat part through the through hole on fixed flat planar part.
The present invention compared with prior art, its remarkable advantage:
(1) structure of the present invention is simple, according to test specimen membraneous material thickness, arbitrarily can regulate spacing between clamping plate, ensure test specimen clamping.
(2) clipping operation of the present invention is convenient, and thicken block mode relative in the past bonding, the present invention can obviously shorten the clamping time, improves test efficiency.
(3) present invention, avoiding the bonding impact on material mechanical performance thickening block mode and bring, simultaneously clamping plate root rounding, the stress efficiently solving test specimen root is concentrated.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
