Description
Technical field
The utility model is related to experimental rigs, and in particular to a kind of hopkinson test bullet filling device.
Background technology
] split hopkinson press bar be now widely used study of rocks class material and concrete dynamic mechanical
The general mechanics method of energy.Experimental sample is clipped between incident bar and transmission bar, and experimental provision can be such that bullet is rushed with different
Speed impacts incident bar is hit, incidence wave is generated in incident bar, when incidence wave propagates to sample, sample is caused to deform,
Back wave and transmitted wave are produced in re-shooting bar and transmission bar respectively at this time, finally by measurement incident bar and transmission bar
Stress wave, obtain the dynamic mechanics parameter of experimental sample using succinct method.However in SHPB after impact test, commonly use
Bullet is pushed into bore tail portion by PVC bars, and since bore is very long, PVC bars push away more past in the backward, in addition bullet weight is big, cause
The difficulty of filling bullet, filling bullet multiple for a long time are a prodigious tests for experimenter's muscle power, also result in reality
Test waste of time.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide a kind of hopkinson test bullet filling device, solutions
The problem of certainly existing bore filling bullet is difficult, complicated for operation, labor intensive.
Technical solution：Hopkinson test bullet filling device described in the utility model, including bore, the bore one

Top and fixed supporting seat, the jack are detachably connected with the support plate, and the fixed supporting seat is arranged in the support
Immediately below seat, the groove being adapted to bore is provided in the support plate.Wherein, jack is hydraulic jack.
It is rotated in order to facilitate bore, the bore and the first bearing pass through fixed axis connection.
Support plate is driven to rise or fall in order to facilitate jack, the jack includes two, two jack difference
It is arranged in the support plate (9) both sides, and passes through fixed axis connection with support plate both sides respectively.
In order to which structure is fixed and is stablized, it is connected and fixed between the fixed supporting seat and jack by connecting pedestal.
In order to enable fixed supporting seat to stablize support plate, the rest of the fixed support
A kind of method of the filling bullet of hopkinson test bullet filling device, includes the following steps：
(1) bullet is placed in bore oral area, the fixing axle for adjusting loose first bearing to be connect with bore adjusts jack, makes branch
Fagging slowly rises, and bore is slowly held up.
(2) bore lifts up to bullet and starts to slide, and fixed jack, bullet slides to bore tail portion, writes down hydraulic pressure thousand
The fixed position on jin top 5；
(3) bullet slides to bore tail portion, adjusts jack, support plate is made to decline, and bore also declines therewith, until branch
Fagging drops on fixed supporting seat, finally tightens the fixing axle that the first bearing is connected with bore, and bullet completes automatic filling.
Advantageous effect：The utility model is easy to operate, adjusts fast, facilitates filling bullet, time saving and energy saving, effectively saves people
Power enables bullet to be combined well with incident bar, and obtained experimental data is true and reliable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the second bearing of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, a kind of hopkinson test bullet filling device, including bore 2, bullet 1, the first bearing and
Two bearings, the first bearing secure the tail portion of bore 2, and the first bearing includes that the first fixing axle 3 supports 4, described first with perpendicular
Perpendicular support 4 is connected to 2 tail portion of bore by fixing axle 3, and bore 2 can be rotated around the first fixing axle 3 and be adjusted, and the first bearing rises main
Fixed function needs to adjust the first fixing axle 3 into the rotation for facilitating bore 2 to suitable tightness, the second bearing before emission bullet 1
Play corrective action.Second bearing includes support plate 8, the second fixing axle 7, fixed supporting seat 9, hydraulic jack 5, connects pedestal 6,
The groove for being used to support bore 2, groove semicircular in shape are offered among 8 upper surface of support plate, groove is adapted with bore 2, makes
Bore 2 will not double swerve when emission bullet 1.Hydraulic jack 5 is connected by the second fixing axle 7 with support plate 8, support plate 8
The rotation of the second fixing axle 7 can be surrounded to adjust, fixed supporting seat 9 is respectively provided in the underface of support plate 8, the both sides of support plate 8
Have a hydraulic jack, hydraulic jack can up and down adjustment support plate 8 height, connection pedestal 6 is by fixed supporting seat 9 and support plate
The hydraulic jack 5 of 8 both sides is connected.Hydraulic jack 5 is connected by connection pedestal 6 with fixed support 9, fixed supporting seat and a left side
In the hydraulic jack insertion connection pedestal of right both sides, be on the one hand easy to disassemble, increased by connecting pedestal
The stability of second bearing plays fixed and stabilization, and the bore 2 when emission bullet 1 is made more to stablize.Support plate 8 or so
Rising or falling for two hydraulic jacks 5 is synchronous progress simultaneously, when support plate 8 is risen to a certain height, hydraulic jack
Top 5 can be fixed, and support plate 8 is fixed height herein, to wait for that bullet 1 slowly slides.Fixed supporting seat 9 and 8 lower end of support plate
It is in contact, when bore 2 is placed in the groove in support plate 8, bore 2 is horizontal, and can will be supported after facilitating filling
Plate 8 recalls to rapidly initial position.Fixed supporting seat 9 includes rest and pedestal, what the rest of fixed supporting seat 9 was contacted with support plate
It is rectangular on one side, preferably the length of side is the square of 5cm, avoids causing very much 8 rising initial stage of support plate to be fixed along second greatly because of rest
The rotation of axis 7 is avoided by the obstruction of fixed support 9 because rest is too small, support plate 8 not exclusively level or the feelings being not sufficiently stable
Condition.The yielding rubber that 2 tail portion of bore is equipped with, buffering when filling slides automatically for bullet 1, avoids more than 1 cunning of bullet
It falls and hits 2 tail portion of bore, influence the pressurization emission bullet 1 of bore 2.
When filling bullet using the utility model, rise support plate first：Ensure that bullet 1 in 2 oral area of bore, adjusts pine first
Fixing axle 3, it is ensured that bore 2 is unobstructed with the rotation of the first fixing axle 3, then adjusts hydraulic jack 5, keeps support plate 8 slow
Rise, bore 2 is slowly held up.Secondly fixed hydraulic jack：When bore 2 is lifted up to a certain angle, bullet 1 starts to slide
It falls, it is not necessary that by 2 Tuo get Tai Gao of bore, fixed hydraulic jack 5, wait for bullet 1 to slide to 2 tail portion of bore, write down hydraulic pressure at this time
The fixed position of jack 5 provides reference to adjust hydraulic jack 5 when follow-up rising support plate 8.Last decent fagging：
Bullet 1 slides to 2 tail portion of bore, adjusts hydraulic jack 5, and support plate 8 is made slowly to decline, and bore 2 is also slowly declined, directly
Drop in fixed support 9 to support plate 8, finally tighten the first fixing axle 3, it is ensured that the first bearing is by 2 fixing-stable of bore, son
Bullet 1 is completed to fill automatically.
