Description
Technical field
The present invention relates to a kind of sample automatic centering device, refer in particular to, when carrying out DWTT,
After the sample bearing of big energy impact testing machine is placed the sample that thickness is 3～40mm, sample is entered
Row carries out the device of centering.
Background technology
DWTT is used to characterize the pilot project of the tough crisp characteristic of material, is mainly used in metal material
Black brittleness research.GB/T8363-2007 " ferritic steel DWTT method " regulation sample from
Taking out in attemperator and load on the sample bearing of testing machine and interrupt rapidly, this process will be in 10 seconds
Complete.At present, test complete use semi-artificial, semi-automatic method to realize, by operator more
Member takes out sample and is put into conveyer, is then sent into testing machine by conveyer.Because artifact affects, make
Whole process of the test is difficult to ensure that and completed in 10 seconds, even if test is to complete also to be difficult in 10 seconds
Judge, result of the test is produced certain impact.It addition, existing automatic sample conveying device cannot solve examination
Sample centering and the problem easily outwelled at the process sample of interrupting, therefore cause testing frequent failure.
Summary of the invention
The technical problem to be solved is to provide a kind of sample in DWTT certainly
Dynamic centralising device, realizes sample automatic centering in process of the test and guarantees that sample does not falls, enabling test
Smoothly complete.
The technical scheme that the present invention solves the problems referred to above is as follows:
A kind of sample automatic centering device in DWTT, including testing machine body, described examination
Test the anvil block being provided with sample bearing on machine body He being symmetrically mounted on sample bearing both sides, it is characterised in that:
The inner side of said two anvil block is respectively mounted magnetic backup plate and the centering plate that bottom is positioned on sample bearing,
Offering through hole on described anvil block, one end of described centering plate is connected affixed horizontal push-pull shaft by latch,
Described push-pull shaft passes through hole, and the other end of push-pull shaft is fixed even with being packed in the centering cylinder outside anvil block
Connect.
On described anvil block install milled screw, described milled screw penetrate from outside to inside anvil block and with magnetic backup plate
It is connected.
The gradient plate being positioned at below sample bearing is installed on described testing machine body.Sample is pounded edge of having no progeny
Gradient plate skids off machine center.
Further, for the operator that damage after preventing process of the test sample fracture, described testing machine body
On protective cover is installed.
The work process of the present invention is, sample is delivered on sample bearing by automatic sample conveying device, centering cylinder
Action, push-pull shaft promotes centering plate to move on bearing, and sample is shifted onto on magnetic backup plate by centering plate, and magnetic leans on
Sample is held by the Magnet on plate, then the action of centering cylinder, and centering plate is retracted by push-pull shaft, prevents punching
When hitting sample, impulsive force is delivered to centering cylinder, is damaged by centering cylinder.Then hammer body release, from
Dynamic falling bodies destroy sample, and whole process completed in 10 seconds, and sample fracture tailing edge gradient plate skids off in machine
The heart.
Compared with prior art, the beneficial effects of the present invention is:
1, the sample automatic centering device of the present invention is no longer necessary to manually participate in process of the test, it is possible to really
Protect DWTT to complete in 10 seconds, it is ensured that the accuracy of result of the test.
2, the present invention is provided with magnetic backup plate, and when sample is shifted onto on magnetic backup plate by centering cylinder, sample absorption exists
On magnetic backup plate, it is ensured that sample will not be toppled in test, it is ensured that test smoothly completes.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention is described in further detail:
Shown in Fig. 1 and Fig. 2, a kind of sample automatic centering device in DWTT,
Including testing machine body A, described testing machine body is provided with sample bearing 4 and is symmetrically mounted on sample and props up
The anvil block 3,3 ' of seat arranged on left and right sides, is wherein positioned on sample bearing bottom the installation of the anvil block 3 in left side
Magnetic backup plate 1, as preferably, described anvil block is installed milled screw 2, and described milled screw is worn from outside to inside
Saturating anvil block is also connected with magnetic backup plate.By rotating milled screw, adjust the position of magnetic backup plate, it is achieved right
Sample is the adjustment of position on sample bearing.Centering plate 5 is installed in another one anvil block 3 ' inner side, shown right
The bottom of middle plate is positioned on sample bearing, and described anvil block 3 ' offers through hole 11, described centering plate
The affixed horizontal push-pull shaft 7 in one end, described push-pull shaft passes through hole 11, the other end of push-pull shaft and being packed in
The fixing connection of centering cylinder 8 outside anvil block.When centering cylinder action, centering plate is released by push-pull shaft
Or retract.
Preferably it is connected by latch 6 between described centering plate and horizontal push-pull shaft.
On described testing machine body A, the gradient plate 9 being positioned at below sample bearing is installed.In order to prevent test
Damage after process sample fracture operator, and described testing machine body is provided with protective cover 10.
As in figure 2 it is shown, the sample automatic centering device of the two set present invention can be installed on testing machine body.
The work process of the present invention is, sample is delivered on sample bearing by automatic sample conveying device, centering cylinder
Action, push-pull shaft promotes centering plate to move on bearing, and sample is shifted onto on magnetic backup plate by centering plate, and magnetic leans on
Sample is held by the Magnet on plate, then the action of centering cylinder, and centering plate is retracted by push-pull shaft, prevents punching
When hitting sample, impulsive force is delivered to centering cylinder, is damaged by centering cylinder.Then hammer body release, from
Dynamic falling bodies destroy sample, and whole process completed in 10 seconds, and sample fracture tailing edge gradient plate skids off in machine
The heart.
