The novel plastic tensile property test clamp is easy to mount and use; meanwhile, the test piece is very convenient to mount and dismount; excessive deformation of a clamped part of the test piece can be avoided.
Description
Technical field
The utility model relates to fixture, specifically a kind of novel plastic tensile property test fixture.
Background technology
The pulling strengrth of polyolefin plastics test piece and breaking elongation test are the essential items for inspection in the quality inspection of multiple conventional pipeline corrosion protection insulating product, very frequent in engineering and the application of product quality inspection field.
At present conventional clamp of stretching tester adopts clamp clamping sample, by the decorative pattern on clamp clamping face and clamp, the snap-in force of sample is produced to stiction, and sample can relatively not moved with clamp in drawing process, thereby guarantees that experimental result is accurate.The fixture applicability of this type is wider, but for thicker sample, because thick sample needs larger tensile force in tension test, in order to guarantee that sample does not relatively move in the time stretching, and needs clamp to apply very large snap-in force to sample and guarantees enough stiction.May bring like this problem of two aspects, the one, it is very tight that clamp need to be pressed, and all brings very big inconvenience to the installation and removal of test specimen; Another aspect is the tension that clamp is pressed, and may cause test specimen to deform at retained part, when serious, causes test specimen to rupture in advance at deformed region, causes stretch test result invalid.
Summary of the invention
The purpose of this utility model is to provide a kind of novel plastic tensile property test fixture, and installation and use are more simple, and the mounting or dismounting of test specimen simultaneously also become very convenient; Also can not cause the excessive deformation of test specimen holding portion.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, a kind of novel plastic tensile property test fixture, comprise jig main body, one end of described jig main body offers the test specimen groove for test specimen is installed, the other end be provided with for the coupling shaft being connected with the stretching examination platform of cupping machine.
The top of described test specimen groove is that test specimen peace is torn hole open, and this hole is through hole, space is provided to installation and removal test specimen.
Described test specimen groove is blind slot, and test specimen groove next-door neighbour's is the test specimen limited block being integrated with jig main body.
Described test specimen groove is wide at the top and narrow at the bottom, and middle part, the test specimen groove left and right sides is provided with the symmetrical pulling force of inside contraction and transmits inclined-plane, and the surface of contact profile that described test specimen groove in-profile will be stretched with test specimen is consistent.
On described coupling shaft, offer the fixed pin holes for link pins is installed, described link pins is connected with the examination platform that stretches simultaneously.
Compared to prior art, the utlity model has following beneficial effect:
This fixture designs fixture inner cavity shape by precision, transmits pulling force by the surface of contact of fixture stenosis and test specimen wedge type part to test specimen.Compared with current conventional fixture, because this fixture does not exist the movable parts such as pressing tongs, fixture installation and use are more simple, and the mounting or dismounting of test specimen simultaneously also become very convenient; Because the snap-in force that no longer relies on pressing tongs is transmitted the pulling force of tensile test specimen, also can not cause the excessive deformation of test specimen holding portion.This test fixture indices meets GB/T 1040 and the requirement of GB/T 8804 series standards to grip of testing machine completely, and applicable specimen thickness scope is 5mm～20mm.

Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
As Figure 1-5, a kind of novel plastic tensile property test fixture, comprises jig main body 1, and one end of described jig main body offers the test specimen groove 2 for test specimen 9 is installed, the other end be provided with for the coupling shaft 7 being connected with the stretching examination platform of cupping machine.The top of described test specimen groove is that test specimen peace is torn hole 4 open, and this hole is through hole, space is provided to installation and removal test specimen.On described coupling shaft, offer the fixed pin holes 3 for link pins is installed, described link pins 10 is connected with the examination platform 8 that stretches simultaneously.
Described test specimen groove is blind slot, and test specimen groove next-door neighbour's is the test specimen limited block 6 being integrated with jig main body.Described test specimen groove is wide at the top and narrow at the bottom, and middle part, the test specimen groove left and right sides is provided with the symmetrical pulling force of inside contraction and transmits inclined-plane 5, and the surface of contact profile that described test specimen groove in-profile will be stretched with test specimen is consistent.After test specimen packs into, the one side of test specimen abuts against on test specimen limited block 6.While carrying out tension test, pulling force transmits inclined-plane 5 by pulling force and transmits.
While carrying out tension test, first fixture 11 is arranged on the stretching examination platform 8 of cupping machine, uses link pins 10 that fixture 11 and the examination platform 8 that stretches are fixed into an entirety.Then pack test specimen 9 into, from Fig. 4, test specimen is installed into fixture 11 by the one side of test specimen groove, as shown in Figure 4 and Figure 5.Mounted test specimen one side should abut against on test specimen limited block 6.
Start subsequently cupping machine, the examination platform 8 that stretches drives slowly two side stretchings up and down of fixture 11, and pulling force is from the examination platform that stretches, fixture, be delivered to test specimen 9 by the inclined-plane (pulling force transmission inclined-plane 5) that contacts between test specimen 9 and fixture 11.
After experiment finishes, stop cupping machine, the examination platform 9 that stretches stops action, now tears open hole 4 and stretches into from the test specimen peace of fixture dorsal part with finger or strip instrument, withstands test specimen tail end, slightly firmly can easily test specimen be ejected.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
