Description
Technical field
It the utility model is related to a kind of detection testing equipment field, more particularly to a kind of tension tester clamp.
Background technology
In being stretched to various materials, compress, bend, shear, the mechanical property test such as tear, extensive utilization pulling force
Testing machine, and tension tester clamp is an indispensable part, clamps sample by fixture and sample is added
Power, to reach the Mechanics Performance Testing to sample.
Prior art refers to the Chinese patent that notification number is CN205209880U, and it discloses a kind of examination of prestressing force pulling force
Test machine clamp, it include jig main body, be longitudinally arranged jig main body upper surface V-groove and be horizontally installed on jig main body
The base portion of lower surface, V-groove are provided with clip tooth on two surfaces, and the tip edges of clip tooth are arranged to round-corner transition, make
The base portion of jig main body is fixed in tensile testing machine by the used time so that two pieces of fixtures are oppositely arranged, it would be desirable to carry out pulling force examination
The specimen holder tested carries out stretching until sample fracture, passes through drawing in two relative V-grooves, by tensile testing machine to sample
The devices such as the sensor on force tester carry out the collection and calculating of data, finally draw testing result.
But the clip tooth tip edges being arranged in the prior art on V-groove surface are arranged to round-corner transition, work as sample
When being clamped in V-groove, the position that clip tooth abuts with sample is the face of arc, if during the surface unusual light of sample, Wu Fayou
Effect by sample holder in V-groove, easily fallen off before sample fracture, so as to be unable to reach detection probe intensity mesh
's.
Utility model content
The purpose of this utility model is to provide a kind of tension tester clamp, and its advantage needs to be detected in clamping
, can be effectively by sample holder in V-groove during sample, when being stretched to sample, sample will not be fallen off easily.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of tensile testing machine folder
Tool, including chuck body, the horizontal V-groove being opened on chuck body front and the cunning for being disposed longitudinally on chuck body another side
Rail, some clip tooths for being used to abut sample are provided with the surface of V-groove.
By using above-mentioned technical proposal, this tension tester clamp can effectively increase the friction between sample
Power, when being detected to sample, sample stress will not also come off between fixture easily.
Preferably, the clip tooth is pyramid shape, its cone angle is 52 degree.
By using above-mentioned technical proposal, rectangular pyramid has extremely strong stability, and 52 degree of angles are most under field conditions (factors)
Stable angle, for clip tooth when being connected to sample, clip tooth will not influence the stabilization fixed to sample because stress crosses strong production deformation
Property.
Preferably, the clip tooth is cone, its cone angle is 52 degree.
By using above-mentioned technical proposal, when conical clip tooth is that sample is engaged, closed space can be formed,
So that the stress of clip tooth, than more uniform, clip tooth will not be broken because stress is too strong, so as to ensure that stabilization during clamping sample
Property.
Preferably, the clip tooth includes base station and the pointed tooth being arranged on base station.
By using above-mentioned technical proposal, the contact point with sample is added in identical contact area so that same
Pressure increase on area suffered by sample, further increase the stability of sample.
Preferably, the pointed tooth is triangular pyramid.
By using above-mentioned technical proposal, triangular pyramid structure has longitudinal holding power most strong in taper, it is corresponding its
Intensity is also very big, and the size of pointed tooth is less than the size of other above-mentioned clip tooths, but pointed tooth has highest intensity, to examination
Sample will not be broken when being clamped because of small volume, further ensure the stability to sample holder.
Preferably, it is carved with graduation mark in the chuck body side wall.
By using above-mentioned technical proposal, it can intuitively see that sample that needs measure is located at the position in fixture, it is right
It is more convenient in the collection of data.
In summary, the utility model has the advantages that：It is pressurized on specimen surface equal area is improved
On the basis of power, the intensity of clip tooth is further increased so that stability of this fixture when to sample holder so that sample is not
It can be fallen off because by very strong power.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Wherein identical parts identical accompanying drawing
Mark represents.It should be noted that the word "front", "rear", "left", "right", the "up" and "down" that are used below in description refer to
It is the direction in accompanying drawing, word " bottom surface " and " top surface ", " interior " and " outer " are referred respectively to towards or away from particular elements geometry
The direction at center.
Embodiment one：
As shown in figure 1, a kind of tension tester clamp, including chuck body 1, longitudinal direction are opened in the upper surface of chuck body 1
V-groove 11 and the slide rail 13 that is horizontally installed on below fixture, be carved with graduation mark 12 in the side wall of chuck body.
With reference to shown in Fig. 2, some clip tooths 2 are provided with two surfaces of V-groove 11, clip tooth 2 is in pyramid shape structure,
And the cone angle of rectangular pyramid is 52 degree.The stability and hardness of rectangular pyramid structure are extremely strong, and under field conditions (factors) 52 degree be most stable
Angle.When using the fixture clamping sample when, clip tooth is connected on sample to 2, specimen surface bear from some clip tooths 2 to its
Pressure so that the pressure of multiple points is born on specimen surface identical area, lifting surface area differs very little with outer surface, but whole
The pressure of body is very big, so as to more consolidate sample holder in V-groove 11.
Embodiment two：
As shown in figure 3, being with the difference of embodiment one, the clip tooth 2 is conical clip tooth 23, and its cone angle is 52
Degree.By setting conical clip tooth 23, circular cone can ensure to be engaged between cone clip tooth 23 and sample when clamping sample, from
And form circular confined space so that the uniform force of conical clip tooth 23, it is not easy to be broken, further ensure folder
Hold the stability of sample.
Embodiment three：
As shown in figure 4, it is with the difference of embodiment one：The clip tooth 2 includes base station 21 and is arranged on base station 21
On some pointed tooths 22, pass through this design so that when sample contacts with pointed tooth 2, there is more stress points, phase on same area
Further increase with the pressure on area, further increase the stability of clamping sample.
Pointed tooth 22 is triangular pyramid, and the size of pointed tooth 22 can be less than the size of clip tooth 2 in above-described embodiment, and triangular pyramid knot
Longitudinal holding power of structure is maximum in tapered structure, and corresponding intensity is also very big, so even if pointed tooth 22 is smaller, still
When being clamped to sample, very big intensity can also be kept by the structure of triangular pyramid, also will not when clamping sample
It is broken because of small volume.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
