Jin top and fixed supporting seat, the jack are detachably connected with the support plate, and the fixed supporting seat is arranged in the branch
It supports 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
Pass through fixed axis connection with support plate both sides.
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 method of the filling bullet of the bullet automatic filling device for SHPB experiments 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 present invention is easy to operate, adjusts fast, facilitates filling bullet, time saving and energy saving, effectively saves manpower,
Bullet is set to be combined well with incident bar, obtained experimental data is true and reliable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the structural schematic diagram of the second bearing of the invention.
Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, a kind of bullet automatic filling device for SHPB experiments, including bore 2, bullet 1, first
Seat and the second bearing, the first bearing secure the tail portion of bore 2, and the first bearing includes the first fixing axle 3 and erects support 4, described
The first fixing axle 3 perpendicular support 4 is connected to 2 tail portion of bore, bore 2 can be rotated around the first fixing axle 3 and be adjusted, the first bearing
Main fixed function is played, needs to adjust the first fixing axle 3 into the rotation for facilitating bore 2 to suitable tightness before emission bullet 1, the
Two bearings play corrective action.Second bearing includes support plate 8, the second fixing axle 7, fixed supporting seat 9, hydraulic jack 5, connection
Pedestal 6, offers the groove for being used to support bore 2 among 8 upper surface of support plate, groove semicircular in shape, and groove is suitable with 2 phase of bore
Match, bore 2 will not double swerve when making emission bullet 1.Hydraulic jack 5 is connected by the second fixing axle 7 with support plate 8, branch
Fagging 8 can surround the rotation of the second fixing axle 7 and adjust, and for fixed supporting seat 9 in the underface of support plate 8, the both sides of support plate 8 are equal
Be provided with hydraulic jack, hydraulic jack can up and down adjustment support plate 8 height, connection pedestal 6 is by fixed supporting seat 9 and branch
The hydraulic jack 5 of 8 both sides of fagging is connected.Hydraulic jack 5 is connected by connection pedestal 6 with fixed supporting seat 9, fixed support
In the hydraulic jack of seat 9 and left and right sides insertion connection pedestal, on the one hand it is easy to disassemble, is on the other hand to pass through linker
Seat increases the stability of the second bearing, plays fixed and stabilization, and the bore 2 when emission bullet 1 is made more to stablize.Support plate
Rising or falling for 8 or so two hydraulic jacks 5 is synchronous progress simultaneously, when support plate 8 is risen to a certain height, hydraulic pressure
Jack 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 support plate 8
Lower end is in contact, and when bore 2 is placed in the groove in support plate 8, bore 2 is horizontal, and can be incited somebody to action after facilitating filling
Support plate 8 recalls to rapidly initial position.The one side that the rest of fixed supporting seat 9 is contacted with support plate is rectangular, and preferably the length of side is
The square of 5cm avoids causing very much 8 rising initial stage of support plate along the rotation of the second fixing axle 7 by fixed support 9 greatly because of rest
Obstruction, avoid because rest is too small, the case where support plate 8 is not exclusively horizontal or is not sufficiently stable.2 tail portion of bore is equipped with slow
Rubber is rushed, buffering when filling slides automatically for bullet 1 avoids more than 1 landing of bullet from hitting 2 tail portion of bore, influences bore 2
Pressurize emission bullet 1.
When filling bullet using the present invention, rise support plate first：Ensure that bullet 1 in 2 oral area of bore, adjusts pine first to fix
Axis 3, it is ensured that bore 2 is unobstructed with the rotation of the first fixing axle 3, then adjusts hydraulic jack 5, and support plate 8 is made slowly to increase,
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, nothing
Need to be 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 jack at this time
5 fixed position provides reference to adjust hydraulic jack 5 when follow-up rising support plate 8.Last decent fagging：Bullet 1 is slided
After dropping down onto 2 tail portion of bore, hydraulic jack 5 is adjusted, support plate 8 is made slowly to decline, bore 2 is also slowly declined, until support
Plate 8 drops in fixed support 9, finally tightens the first fixing axle 3, it is ensured that for the first bearing by 2 fixing-stable of bore, bullet 1 is complete
At automatic filling.
