Description
Technical field
The utility model is related to a kind of specimen holders of experiment, particularly belong to a kind of thin plate high-speed stretch sample alignment folder
Tool, it is especially suitable for the high-speed stretch sample line-up jigs of Steel Plate Used for Vehicle Body.
Background technology
Automotive light weight technology design is the Major Strategic in current various countries' automotive technology development planning.Related data shows vapour
Vehicle dead weight often mitigates 10%, and fuel consumption can reduce by 6% ~ 8%, i.e. automotive light weight technology has energy-saving and environment-friendly effect.Due to automobile
Safety is embodied directly in the ability that Impact energy is absorbed during vehicle body strikes and the degree of protection to occupant, and knockout process
The deformation of middle material is the dynamic response of a high strain rate, so the dynamic force of research Steel Plate Used for Vehicle Body at high speeds
Scholarship and moral conduct is to have guidance to optimizing structure design, reasonably select material, raising bodywork safety in automotive light weight technology development process
Effect.
Testing equipment applied to metal material high speed dynamic test have hydraulic servo high speed tensile test machine,
Hopkinson bars etc..At present using more hydraulic servo high speed tensile test machine maximum load 50KN, maximum test rate is
20m/s, sample frequency 10MHz, typical strain rate are 0.1-1000s-1.Wherein sample holder position uses Wedge gripping,
Chucking surface uses tooth surface design, increases the frictional force between sample and fixture.
It is found by long-time experiment, if the sample both ends of experiment are in irregular shape, when installing sample, up and down
Retaining part alignment difficulty is big, cannot achieve test objective.At present during installing sample, typically by the end of sample
The bottom for withstanding upper fixture is mounted with upper fixture and then the other end of sample is packed into lower fixture.If sample end is uneven
Or it is not regular oblong, it is easy to fill sample partially, parallel portion and test scale load direction are inconsistent, and it will cause experiments
It obtains load-deformation curve and practical legitimate reading error is larger, affect test effect.
Utility model content
The utility model is in view of the deficienciess of the prior art, to provide a kind of alignment of sample quick and easy, accurate, and makes
With thin plate high-speed stretch sample line-up jig that is safe and reliable, easily implementing.
Realize the technical measures of above-mentioned purpose：
A kind of thin plate high-speed stretch sample line-up jig, by upper fixture block, the lower fixture block, the upper fixture block that are used cooperatively with upper fixture block
And the connecting hole composition of two symmetric configurations being equipped with of lower fixture block, it is：Upper fixture block two symmetrical connecting holes it
Between centre be equipped with wedge-shaped straight slot one, half wedge block one and half wedge block two are housed in wedge-shaped straight slot one, in half wedge block
One or half wedge block two is equipped with U-shaped tensile sample slot one；Centre is set between two symmetrical connecting holes of lower fixture block
There is wedge-shaped straight slot two, half wedge block three and half wedge block four is housed in wedge-shaped straight slot two, in half wedge block three or half wedge block
Four are equipped with U-shaped tensile sample slot two；U-shaped tensile sample slot one is arranged with U-shaped tensile sample slot two on same center line, and
Form and dimension is identical.
It is：The planform and size phase of wedge-shaped straight slot one and the wedge-shaped straight slot two in lower fixture block in upper fixture block
Together.
It is：The width of U-shaped tensile sample slot one and U-shaped tensile sample slot two is matched with the width of made sample.
The characteristics of the utility model：Sample alignment is quick and easy, accurate and safe and reliable, shortens the test period not
Less than 10min, easily implement.

Specific implementation mode
It is described further below in conjunction with the accompanying drawings：
A kind of thin plate high-speed stretch sample line-up jig, the lower fixture block 2 being used cooperatively by upper fixture block 1, with upper fixture block 1, on
The connecting hole 3 for two symmetric configurations processed on fixture block 1 and lower fixture block 2 forms, and two in upper fixture block 1 symmetrically connect
The processing wedged straight slot 1 in centre between hole 3 is equipped with half wedge block 1 and half wedge block 26 in wedge-shaped straight slot 1,
Half wedge block 1 or half wedge block 26 are equipped with U-shaped tensile sample slot 1；Lower fixture block 2 two symmetrical connecting holes 3 it
Between the processing wedged straight slot 28 in centre, half wedge block 39 and half wedge block 4 10 are housed, in half wedge in the wedge-shaped straight slot 28
U-shaped tensile sample slot 2 11 is processed on shape block 39 or half wedge block 4 10；U-shaped tensile sample slot 1 and U-shaped tensile sample slot
2 11 are arranged on same center line, and form and dimension is identical.
Wedge-shaped straight slot 1 in upper fixture block 1 is identical as the planform of the wedge-shaped straight slot 2 11 in lower fixture block 2 and size.
The width of U-shaped tensile sample slot 1 and U-shaped tensile sample slot 2 11 is matched with the width of made sample.
Practical principle
One end of sample is mounted in the U-shaped tensile sample slot 1 on half wedge block 26 of upper fixture 1；Again by sample
The other end be mounted on lower fixture 2 half wedge block 4 10 on U-shaped tensile sample slot 2 11 in；And it is mounted in respectively by tightening
The screw rod of connecting hole 3 makes half wedge block 1 and half wedge block 26, and half wedge block 39 and half wedge block 4 10 are respectively by sample
It clamps.High speed tensile test work is carried out afterwards.
Present embodiment is only the best example, not to the restricted implementation of technical solutions of the utility model.
