Abstract
The utility model relates to a sheet stretching sample collet having a spacing function. The collet is characterized in that the collet comprises an upper collet and a lower collet, the upper collet is composed of an upper left clamping block and an upper right clamping block, the lower collet is composed of a lower left clamping block and a lower right clamping block, the upper left clamping block is provided with an upper spacing bolt, the upper right clamping block is provided with an upper spacing bolt hole corresponding to the upper spacing bolt, the lower left clamping block is provided with a lower spacing bolt, and the lower right clamping block is provided with a lower spacing bolt hole corresponding to the lower spacing bolt. The sheet stretching sample collet can avoid the skidding or non-vertical disposing phenomenon of a sample in a test process, and allows the symmetric axis direction of the sheet sample to be the vertical direction and be consistent with the applied load direction of a test machine in order to obtain accurate measure data.
Description
Technical field
The utility model relates to a kind of chuck, particularly a kind of plate stretch sample chuck with limit function.
Background technology
In the sheet coupon tension test, there is considerable influence to sample imposed load direction and the symmetrical axial consistance of sample in cupping machine to the test findings accuracy.Testing machine imposed load direction is vertical direction, and when sample axis of symmetry direction and this direction were consistent, then suffered load was consistent with testing machine registration load on the sample cross; When there are an angle in sample axis of symmetry direction and imposed load direction, then suffered load is that testing machine registration load is along the symmetrical axial one-component of sample on the sample cross, just there is deviation in the test findings that obtain this moment with actual value, can't obtain this sample mechanical performance index actual value, cause the sample testing data inaccurate, impact is to the objective evaluation of this quality of materials.
The utility model content
Technical problem to be solved in the utility model provides a kind of plate stretch sample chuck of drawstring limited location function, can realize that sheet coupon axis of symmetry direction is vertical direction, and is consistent with testing machine imposed load direction, to obtain more accurately measurement data.
The utility model is taked following technical scheme:
A kind of plate stretch sample chuck with limit function, it comprises upper grip and lower chuck, described upper grip is comprised of upper left fixture block and upper right fixture block, described lower chuck is comprised of bottom left fixture block and bottom right fixture block, described upper left fixture block is provided with the upper limit bolt, described upper right fixture block is provided with the upper limit keyhole corresponding with described upper limit bolt, described bottom left fixture block is provided with the lower limit bolt, described bottom right fixture block is provided with the lower limit keyhole corresponding with described lower limit bolt, and it is vertical direction that described upper limit bolt and lower limit tie the line direction.
The obtained beneficial effect of the utility model is: because a kind of plate stretch sample chuck with limit function provided by the utility model, it comprises upper grip and lower chuck, described upper grip is comprised of upper left fixture block and upper right fixture block, described lower chuck is comprised of bottom left fixture block and bottom right fixture block, described upper left fixture block is provided with the upper limit bolt, described upper right fixture block is provided with the upper limit keyhole corresponding with described upper limit bolt, described bottom left fixture block is provided with the lower limit bolt, and described bottom right fixture block is provided with the lower limit keyhole corresponding with described lower limit bolt.It is vertical direction that described upper limit bolt and lower limit tie the line direction.In use, a kind of plate stretch sample fixture block with limit function provided by the utility model is put into the chute that connects the sample chuck to be fixed with the plate stretch machine, sample one side is adjacent to upper limit bolt and lower limit bolt, and be close to upper left fixture block and bottom left fixture block, then regulate the position of upper right fixture block and bottom right fixture block by the testing machine control device, and make upper left fixture block with the upper limit bolt enter upper right fixture block with the upper limit keyhole in, and make the bottom left fixture block with the lower limit bolt enter the bottom right fixture block with the lower limit keyhole in, guarantee the tight sample of chuck.So can avoid like this sample generation skidding or placement off plumb phenomenon in process of the test.So that sample axis of symmetry direction and vertical direction are consistent, make load suffered on the sample cross consistent with testing machine registration load, obtain this sample mechanical performance index actual value.
Description of drawings
Fig. 1 is synoptic diagram of the present utility model.
Fig. 2 is that upper right fixture block of the present utility model is with the synoptic diagram of upper limit keyhole.
In the drawings: 1 upper left fixture block, 2 upper limit bolts, 3 upper right fixture blocks, 4 upper limit keyholes, 5 bottom left fixture blocks, 6 lower limit bolts, 7 bottom right fixture blocks, 8 lower limit keyholes.
Embodiment
As shown in drawings, the utility model comprises upper grip and lower chuck, described upper grip is comprised of upper left fixture block 1 and upper right fixture block 3, described lower chuck is comprised of bottom left fixture block 5 and bottom right fixture block 7, described upper left fixture block 1 is provided with upper limit bolt 2, described upper right fixture block 3 is provided with the upper limit keyhole 4 corresponding with described upper limit bolt 2, described bottom left fixture block 5 is provided with lower limit bolt 6, described bottom right fixture block 7 is provided with the lower limit keyhole 8 corresponding with described lower limit bolt 6, and described upper limit bolt 2 is vertical direction with lower limit bolt 6 line directions.The diameter of upper limit bolt 2 and lower limit bolt 6 is that 5mm length is 10mm in the utility model, upper limit bolt 2 is installed in apart from upper left fixture block 1 lower limb 10mm place, lower limit bolt 6 locating distances are at bottom left fixture block 5 coboundary 10mm places, upper limit bolt 2 and lower limit bolt 6 are installed in 5mm place, fixture block vertical direction axis of symmetry the same side, and two limited bolt line directions are vertical direction; Upper right fixture block 3, bottom right fixture block 7 are respectively processed a diameter 6mm in corresponding limited bolt position respectively, the upper limit keyhole 4 of degree of depth 11mm and lower limit keyhole 8, when guaranteeing that upper lower chuck clamps sample, limited block enters into spacing keyhole, does not affect fixture block and clamps sample.
In use, sample one side is adjacent to upper limit bolt 2 and lower limit bolt 6, and be close to upper left fixture block 1 and bottom left fixture block 5, then regulate the position of upper right fixture block 3 and bottom right fixture block 7 by the testing machine control device, and make upper left fixture block 1 with upper limit bolt 2 enter upper right fixture block 3 with upper limit keyhole 4 in, and make bottom left fixture block 5 with lower limit bolt 6 enter bottom right fixture block 7 with lower limit keyhole 8 in, guarantee that fixture block clamps sample.Can avoid like this sample generation skidding or placement off plumb phenomenon in process of the test.So that sample axis of symmetry direction and vertical direction are consistent, make load suffered on the sample cross consistent with testing machine registration load, obtain this sample mechanical performance index actual value.
Certainly, personnel are known as present technique, if the sample to different model detects, can replace the data size in the present embodiment, but the plate stretch sample fixture block with limit function after replacing all should be encompassed within the claim scope of the present utility model.
