Description
Technical field
This utility model is related to tensile test fixture technical field and in particular to a kind of testing machine for mechanical properties tension test
Use Test stick clamp.
Background technology
At present, the tensile test bar clamping device of the testing machine of testing machine for mechanical properties manufacturer production is using upper and lower v a bit
Type teeth groove chuck, two pieces of top, two fixture blocks, during clamping, are closed up using hydraulic pressure or air pressure and for coupon two to be clipped in v by two pieces of bottom
In type groove, then rely on V-shaped rake tooth engaging-in coupon head, coupon is broken.Following lacking, is had using this tensioning technique
Point: when 1, coupon material hardness is high (hrc >=40), chuck skidding easily occurs, sometimes due to V-shaped tooth cannot be engaging-in, at all
Coupon cannot be broken.2nd, the tooth of V-shaped groove chuck is perishable, because the hardness of tooth is high and fragility is big, after using several times, often occurs
Broken teeth and abrasion, thus cause the phenomenon that stretching is skidded.After occurring skidding, just cannot be carried out tension test, need to change
New fixture block just can work on, and the buying expenses of fixture block is typically all higher, under normal circumstances, if all stretched daily
During test, typically need replacing to overpay every year, cause very high maintenance cost.
Utility model content
The purpose of this utility model is to provide one kind simple and practical, non-slip during test, is capable of the mechanical property of life-time service
Can testing machine tension test Test stick clamp.
In order to solve the problems of background technology, this utility model is to employ the following technical solutions: a kind of mechanical property
Energy testing machine tension test Test stick clamp, including machine upper grip, upper extension workpiece, upper rectangular thread fixture block, lower extension workpiece, machine
Device lower chuck, lower rectangular thread fixture block and tensile test bar, described machine upper grip by upper rectangular thread fixture block with described on
The screw rod hanging workpiece is connected, and described machine lower chuck is connected with the described lower screw rod hanging workpiece by lower rectangular thread fixture block, institute
State and hang the center of workpiece and lower extension workpiece and have the upper notch matching with described tensile test bar and a lower notch, described draw
The upper and lower end stretching coupon is individually positioned in the upper notch of described upper extension workpiece and in the lower notch of described lower extension workpiece.
Further, the upper/lower terminal of described tensile test bar is all in step-like.
Further, form a complete rectangle spiral shell after described upper rectangular thread fixture block and lower rectangular thread fixture block close up
Female.
This utility model has the advantages that a kind of testing machine for mechanical properties tension test described in the utility model
With Test stick clamp, including machine upper grip, upper extension workpiece, upper rectangular thread fixture block, lower extension workpiece, machine lower chuck, lower rectangle
Screw thread fixture block and tensile test bar, described machine upper grip is by upper rectangular thread fixture block and the described upper screw rod phase hanging workpiece
Even, described machine lower chuck is connected with the described lower screw rod hanging workpiece by lower rectangular thread fixture block, described upper extension workpiece with
The center hanging workpiece has the upper notch matching with described tensile test bar and a lower notch, described tensile test bar upper and lower
End is individually positioned in the upper notch of described upper extension workpiece and in the lower notch of described lower extension workpiece；This utility model adopts above-mentioned
Structure, its coupon can not need clamping head portion, relies on the step stress of coupon inner portion, coupon head will not be because of clamping
Problem produce skid, gripping block will not be damaged, so that it is guaranteed that fixture block will not be able to be lost efficacy with life-time service.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to Fig. 1, this specific embodiment employs the following technical solutions: a kind of testing machine for mechanical properties tension test examination
Rod clamp, including machine upper grip 1, upper extension workpiece 2, upper rectangular thread fixture block 3, lower extension workpiece 4, machine lower chuck 5, lower rectangle
Screw thread fixture block 6 and tensile test bar 7, described machine upper grip 1 is by upper rectangular thread fixture block 3 and the described upper spiral shell hanging workpiece 2
Bar is connected, and described machine lower chuck 5 is connected with the described lower screw rod hanging workpiece 4 by lower rectangular thread fixture block 6, described upper extension work
Part 2 and the lower center hanging workpiece 4 have the upper notch 2-1 matching with described tensile test bar 7 and lower notch 4-1, described
The upper and lower end of tensile test bar 7 is individually positioned in the described upper interior and described lower lower notch hanging workpiece 4 of upper notch 2-1 hanging workpiece 2
In 4-1.Wherein, the upper/lower terminal of described tensile test bar 7 is all in step-like.Described upper rectangular thread fixture block 3 and lower rectangular thread
Fixture block 6 forms a complete rectangular nut after closing up.This utility model, when stretching-machine works, relies on inside coupon two
Step stress breaks coupon；By way of changing original dependence direct clamping coupon two and carrying out tension test, take and disobey
By clamping, but rely on the step stress tensile test bar inside coupon two, change the fragile mistake of original V-shaped groove toothholder block
Effect, it is often necessary to change the phenomenon of chuck, has saved maintenance cost.
In addition, in the present embodiment, above-mentioned upper hang workpiece 2 and lower hang the position that workpiece 4 is connected with tensile test bar 7, permissible
It is designed to loose piece, loose piece and tensile test bar 7 connecting portion press the arc machining inside two of coupon, cut open by after annulus processing again
Into two it is also possible to reach the purpose relying on stress inside coupon two to carry out mechanical property test.
In sum, this Test stick clamp is the mode that clamping coupon two carries out coupon stretching, is changed to rely on coupon
The mode of two inner side step stress carries out coupon tension test, and the suspension member of increase is connected by rectangular thread, both with machine
Ensure that and can bear the concentricity that big force value in turn ensures that suspension member.
Finally illustrate, above example only in order to the technical solution of the utility model is described and unrestricted, this area
Other modifications or equivalent that those of ordinary skill is made to the technical solution of the utility model, without departing from this practicality
The spirit and scope of new technique scheme, all should cover in the middle of right of the present utility model.
