The root at end coordinates with square groove；Described rotate is provided with the first sample groove of indent on the inside of bare terminal end, be provided with the middle part of square groove with
The sample of product is placed in second sample groove corresponding to first sample groove, the first sample groove and the second sample groove.
Its further technical scheme is：
The both sides of the square groove have guide rail, the guide rail long circle structure, and hinge is arranged in guide rail.
One end of the first sample groove and the second sample groove is mounted on rocker piece, and the rear end of the rocker piece is pressure
Sensor.
The first sample groove right-hand member installation rocker piece and pressure sensor.
The left end of the second sample groove is provided with rocker piece and pressure sensor.
The end upper and lower surface of the horizontal bare terminal end is provided with the first anti-slip veins.
The end upper and lower surface for rotating bare terminal end is provided with the second anti-slip veins.
Beneficial effects of the present invention are as follows：
The present invention is compact-sized, reasonable, easy to operate, by will require that the sample of processing is placed on folder according to certain size
In square groove in tool, stretched by the bare terminal end of sample machine stationary fixture according to test requirements document, be effectively guaranteed experiment
The progress of process stabilization, the mechanical property of real reaction test sample, meet increasingly rigorous scientific research requirements.
Patent of the present invention, it is effectively guaranteed the progress of experiment process stabilization, the mechanical property of real reaction test sample
Can, meet increasingly rigorous scientific research requirements.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1st, the first anti-slip veins；2nd, bare terminal end is rotated；3rd, the first sample groove；4th, anti-loosing screw；5th, horizontal bare terminal end；
6th, the second anti-slip veins；7th, the second sample groove；8th, rocker piece；9th, pressure sensor；10th, guide rail；11st, sample；12nd, square groove.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is illustrated.
As shown in figure 1, the grip device of the detection sample shearing strength of the present embodiment, including horizontal bare terminal end 5, level folder
Hold 5 upper surfaces of end and be provided with square groove 12, the end of square groove 12 is provided with by hinge rotates bare terminal end 2, and anti-in the installation of its both ends
De- screw 4, the root for rotating bare terminal end 2 coordinate with square groove 12；The inner side for rotating bare terminal end 2 is provided with the first sample groove 3 of indent,
The middle part of square groove 12 be provided with 3 corresponding second sample groove 7 of the first sample groove, place in the first sample groove 3 and the second sample groove 7
The sample 11 of product.
The both sides of square groove 12 have guide rail 10, the long circle structure of guide rail 10, and hinge is arranged in guide rail 10.
One end of first sample groove 3 and the second sample groove 7 is mounted on rocker piece 8, and the rear end of rocker piece 8 is pressure sensing
Device 9.
The right-hand member of first sample groove 3 installs rocker piece 8 and pressure sensor 9.
The left end of second sample groove 7 is provided with rocker piece 8 and pressure sensor 9.
The design of rocker piece 8 and pressure sensor 9 of the present invention, in that context it may be convenient to which realization accurately detects during experiment
The situation of device stretcher strain.
The end upper and lower surface of horizontal bare terminal end 5 is provided with the first anti-slip veins 1.
The end upper and lower surface for rotating bare terminal end 2 is provided with the second anti-slip veins 6.
The sample 11 of product testing divides for three parts, respectively top material, intermediate layer material and lower material, fixture
Local detail is guide rail 10 and anti-loosing screw 4, and the material of sample 11 can be able to be different, the present invention is mainly with identical
For the experiment of dissimilar material joining sample.
In practical work process, two bare terminal ends (rotating bare terminal end 2 and horizontal bare terminal end 5) assembling is completed, loads onto anticreep
Screw 4, square groove 12 is interior to place the sample 11 that processing is required according to certain size, and two bare terminal ends are closed and are put into stretching-machine respectively
On, in checkout procedure, the first anti-slip veins 1 and the second anti-slip veins 6 are carved with the bare terminal end of fixture, increase effectively frictional force, prevented
Only the problems such as skidding in detection process, device is mainly stretched the stretching action of machine in experiment, and bare terminal end is in guide rail 10
Effect is moved along draw direction, and when dynamics reaches to a certain degree, top material and lower material are punished in intermediate layer material
From the dynamics shown by pressure sensor 9 and stretching-machine, which passes through conversion, can obtain the reliable shearing strength number of true and accurate
According to.
