In pod be V-shaped groove, the two ends by test specimen insert respectively two positioning bearing block cross recess translots in, be rotated by 90 °
Afterwards, fitted by test specimen side with V-shaped groove inwall in positioning bearing block.
The universal fixturing of above-mentioned material tension test, the holder outer surface is provided with diamond-shaped knurling.
The universal fixturing of above-mentioned material tension test, the outer shroud opposite side is provided with ring sealing plate, shrouding and is arranged with
Two are used to be used for the through hole by bearing block ejection outer shroud is positioned through the screw of trip bolt and 2.
The universal fixturing of above-mentioned material tension test, the groove width of the direct through groove is more than by specimen thickness.
The universal fixturing of above-mentioned material tension test, the angle of the V-groove is equal to by test specimen side angle, V-groove groove
Bottom diameter is more than or equal to is tested position width by test specimen.
The universal fixturing of above-mentioned material tension test, institute is small in the big centre of flat and two by test specimen.
The beneficial effects of the utility model are:The utility model is through with cross recess on positioning bearing block, passes through ten
The cooperation of the direct through groove of word groove and V-shaped groove is realized by the fixation of test specimen, changes the experiment method clamped by frictional force, tool
Have the advantages that simple and compact for structure, manufacturing process is simple, with low cost, it is applied widely.
