Abstract
The invention discloses a kind of tension test machine grip holders of test plants stalk mechanical property, are mainly made of collet body 1 and connecting rod 8 and clamping jaw 2；Wherein clamping jaw 2 is by jaw body 3, and liquid capsule 4, contacts shield 5 and liquid 6 forms；Clamping jaw is made of symmetrical two parts；Jaw surfaces contact shield and use flexible material, it can be achieved that flexible clamping, reduces stalk surface stress and concentrate；The jaw surfaces contact shield can require more conversion materials according to different stalks；Jaw surfaces contact shield can smear binder to increase frictional force；Liquid capsule built in clamping jaw, it is interior filled with incompressible liquid, it is adapted to different stalk shapes；A kind of tension test machine grip holder of test plants stalk mechanical property disclosed by the invention has the following characteristics that flexible clamping, does not damage stalk；It is tightly combined, will not slide with stalk.
Description
Technical field
The present invention relates to a kind of tension test machine grip holder, especially a kind of tension test of test plants stalk mechanical property
Machine grip holder.
Background technique
Currently, needing to carry out tension test to crop stem before to agricultural cutter tool design, to study corresponding crop
Mechanical property.But existing stretcher is mostly metallic material testing machine, collet is mostly Steel material, clamps loose stalk meeting
Sliding will cause stalk damage or even direct pinch off again, can not adapt to the clamping of fragile stalk when clamping tension.
Summary of the invention
The purpose of the invention is to overcome above-mentioned existing deficiency, a kind of tension test machine grip holder is provided, the collet knot
Structure is simple, easy to use, and versatility is good.
To achieve the above object, the present invention adopts the following technical solutions；A kind of stretching of test plants stalk mechanical property
Machine grip holder is tested, is mainly made of collet body 1 and connecting rod 8 and clamping jaw 2；Wherein clamping jaw 2 contacts shield by jaw body 3, liquid capsule 4
5 and liquid 6 form.
The clamping jaw is made of symmetrical two parts.
The clamping jaw is that inclined-plane couples with collet body, may be implemented to become connecting rod vertical movement as clamping jaw open and close movement.
The described jaw surfaces contact shield uses flexible material, it can be achieved that flexible clamping, to reduce stalk surface stress
It concentrates.
The jaw surfaces contact shield can require more conversion materials according to different stalks.
The jaw surfaces contact shield can smear binder to increase frictional force.
Liquid capsule built in the clamping jaw, it is interior filled with incompressible liquid, it is adapted to different stalk shapes.
A kind of tension test machine grip holder of test plants stalk mechanical property disclosed by the invention has the following characteristics that flexibility
Clamping, does not damage stalk；It is tightly combined, will not slide with stalk.
Detailed description of the invention
Fig. 1 is the front schematic view of the tension test machine grip holder of test plants stalk mechanical property.
The meaning that each legend label respectively indicates in attached drawing is as follows: 1 is collet body, and 2 be clamping jaw, and 3 be jaw body, and 4 be liquid
Capsule, 5 be contact shield, and 6 be liquid, and 7 be test stalk, and 8 be connecting rod.
Specific embodiment
Specific embodiment is provided with reference to the accompanying drawing.
One embodiment of the present of invention is the tension test of plant haulm, specific as shown in Figure 1.It is selected according to Culm traits
The higher flexible material of coefficient of friction is contact shield 5, and the liquid capsule 4 and contact shield 5 that will be filled with liquid 6 are sequentially arranged at clamping jaw
On body 3；It is pulled up connecting rod 8, separates clamping jaw 2；Binder is smeared on contact 5 surface of shield as needed；Stalk 7 will be tested
It is put among clamping jaw 2；It is pressed downward being close to bar 8, clamping jaw 2 is closed, and test stalk 7 is clamped in advance, stalk 7 will not fall off；Testing machine
After force, clamping jaw 2 continues to clamp, and clamps more secured.
It ties full attached drawing although above-mentioned tool embodiment of the invention is described, not to the scope of the present invention
Limitation, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not required to
Make the creative labor the various modifications or changes that can be made still within protection scope of the present invention.
