Technical field
The utility model is related to a kind of fixture, more particularly to a kind of universal fixturing of material tensile test.
Background technology
Stretching experiment is the means of common techniques that prepared by new material, material property is examined, the number obtained using tension test According to tensile strength, elongation, area reduction amount, yield strength and the other tensile property indexs of material can be determined.Common, For tensile test of metallic materials, vice type chuck is typically carried using hydraulic tensioner test specimen two is clamped by frictional force , also there is the Wedge gripping that theory structure is locked using inclined-plane at end, i.e., with the increase of test force, clamping force increases therewith.For Wedge gripping, frictional force is as clamping force between specimen surface and fixture, and initial clamping force is small, as test force increases, and clamps Power gradually increases therewith.The operation of this two ways is simple, with low cost, but there is also some problems, is pressed from both sides such as in drawing process Clamp force is excessive easily to split test piece end pinch off, and clamping force is too small, easily causes and occurs specimen surface during tension test Skid, produce cut, be easily caused scrapping, it is necessary to which clamping is repeated several times for sample, causing the cost of experiment increases, conventional efficient Lowly, and influence experimental data accuracy.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of simple in construction, cost low material tensile test Universal fixturing.
The technical scheme that the utility model solves the above problems is:A kind of universal fixturing of material tensile test, including quilt Test specimen and two clamp systems being oppositely arranged, the clamp system include holder, positioning bearing block, lock-screw, outer shroud, The holder is threaded in outer shroud side, and the positioning bearing block is fixed in outer shroud inner chamber with lock-screw, and positioning is held Cross recess is through with pouring weight, the translot that the middle part of cross recess is provided with manhole, the cross recess is direct through groove, cross recess 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.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Fig. 2-Fig. 8, the utility model includes the clamp system 11 being oppositely arranged by test specimen 5 and two, the folder Tight mechanism 11 includes holder 1, positioning bearing block 2, outer shroud 4, and the holder 1 is threaded in the side of outer shroud 4, holder 1 Outer surface is provided with diamond-shaped knurling, to improve clamping friction power;The opposite side of outer shroud 4 is provided with ring sealing plate 6, shrouding and symmetrically set There are 41,2 through holes 41 of two screws 42 and 2 through holes to be used to be fixed on outer shroud 4 by bearing block 2 is positioned through lock-screw 3, Positioning bearing block 2 is ejected outer shroud 4 by 2 screws 42 when positioning bearing block 2 to replace, and it is fixed to be caused by screw 42 and through hole 41 Position bearing block 2 be replaceable type design, according to by the side angle α of test specimen 5, position width C and bare terminal end width are tested by test specimen 5 The parameters of A tri- can enter the different types of positioning bearing block 2 of line replacement in certain limit, improve the versatility of fixture.The positioning is held Pouring weight 2 is fixed in the inner chamber of outer shroud 4 with lock-screw 3, is through with cross recess 7 on positioning bearing block 2, the middle part of cross recess 7 is set It is direct through groove to have the translot in manhole 8, the cross recess 7, and the groove width of direct through groove is slightly larger than by the thickness of test specimen 5, cross recess 7 In pod be V-shaped groove, the angle β of V-groove is equal to by the side angle α of test specimen 5, and V-groove groover rot diameter c is more than or equal to by test specimen 5 subject position width Cs, it is described small in the big centre of flat and two by test specimen 5, two are inserted respectively by the two ends of test specimen 5 determines In the translot of the position cross recess 7 of bearing block 2, after being rotated by 90 °, it is affixed by the side of test specimen 5 with V-shaped groove inwall in positioning bearing block 2 Close.
