Description
Technical field
The invention belongs to centrifuge technique fields, and in particular to a kind of centrifugation machine table top of acceleration test fixes dress
It sets.
Background technique
Since the mode that different tests equipment generates acceleration load is different, so when selecting acceleration test equipment,
Because carefully analyzing the function and characteristic of test specimen.Common equipment has two classes: centrifuge and prizing with sliding rail rocket.Centrifuge is to pass through
It is rotated around fixing axle and generates acceleration load, so acceleration direction is always directed radially towards the axis of rotation of centrifuge,
And the loading direction as caused by acceleration always from axis of rotation radially.When test specimen is directly installed on centrifuge experiment
When on arm, then test specimen bears two kinds of rotation and translation movements simultaneously.For given rotating speed, acceleration and acceleration suffered by test specimen
Loading direction caused by spending makes constant, but pivoted arm every revolution, test specimen will rotate 360 °.Another characteristic of centrifuge makes to accelerate
Load caused by spending is with test specimen away from directly proportional at a distance from axis of rotation.The existing centrifuge for acceleration test, due to
Work top rotation is not fixed, usually more difficult test specimen is adjusted to suitable position to be fixedly clamped when installing test specimen, causes to install
Test specimen is time-consuming and laborious, and common fixation device does not have detection function, and user does not know whether work top relieves fixing shape
State causes usually to start centrifuge under work top stationary state, device is caused to damage.
Summary of the invention
The purpose of the present invention is: the centrifugation machine table top for being intended to provide a kind of acceleration test fixes device, is not only needing
Work top can be fixed when test specimen is installed, and there is detection function, prevent the shape that staff is fixed in work top
Starting centrifuge under state leads to fixed device damage, safe and reliable.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
A kind of centrifugation machine table top of acceleration test fixes device, including rack backplate, bottom plate, servo motor, photoelectricity
Encoder, centrifugation machine support, motor mount, working chamber backplate, working rotary table, collecting ring, cover board and processor, the centrifugation
Machine support includes supporting table, and the rack backplate and cover board are hinged, and the processor is equipped with processing chip and buzzer, the place
It manages device side and is equipped with storage box, the storage box is equipped with positioning pin, and the positioning pin includes round bar, and the round bar upper end is equipped with and mentions
Pull rod, is equipped with conical inclined surface on the downside of the round bar, and the cover board is equipped with rectangular key block, and the working chamber backplate inner wall is equipped with the
One detection switch bracket, the first detection switch bracket are fixedly connected with the first detection switch to match with rectangular key block, institute
It states working rotary table to be uniformly distributed there are four the through-hole to match with positioning pin, the supporting table is equipped with to match with conical inclined surface
Bolt through-hole, the supporting table lower surface is fixedly connected with that there are four second to match with bolt through-hole close to switch bracket,
Four described second are connected separately with second close to switch, third close to switch, the 4th close to switch and the close to switch bracket
Five close to switch, and the rack backplate, which is equipped with, to match the first maintenance window with second close to switch, first maintenance window
It is bolted the first maintenance cover board, the rack backplate is equipped with the second maintenance window to match with third close to switch, institute
State the second maintenance window and be bolted the second maintenance cover board, the rack backplate be equipped with collecting ring, the 4th close to switch and
The 5th third maintenance window to match close to switch, the third maintenance window have been bolted third service cover plate；
The processor power supply output end is electrically connected with servo motor and buzzer, the processor signal input terminal and
One detection switch, second connect with the 5th close to switching signal close to switch, third close to switch, the 4th close to switch.
Using technical solution of the present invention, when needing to install test specimen, cover board is opened, four positioning pins are taken out from storage box
And it is inserted into through-hole, it is inserted into positioning pin in bolt through-hole by rotation work turntable, conical inclined surface closely connects with bolt through-hole
Touching, working rotary table are fixed by positioning pin, bolt through-hole and through-hole cooperation, are easily installed test specimen, and pass through on the downside of conical inclined surface
Widow bolts through-hole reaches on the downside of supporting table, makes second close close to switch, the 4th close to switch and the 5th close to switch, third
Switch detects signal, all collects positioning pin by extracting lifting rod after installing test specimen and puts back in storage box, closes
Cover board is closed, only after the first detection switch detects the signal of rectangular key block, servo motor could be started by processor and started
Test, guarantees to cause to damage to staff due to maloperation when installing test specimen in this way；If operator is careless
Fail to take all positioning pins away, though covering cover board, after processor receives the first detection switch signal, processor detection
To second close to switch, third close to switch, the 4th close to switch or the 5th close to switch any one switching signal when, place
Reason device not will start servo motor still, and buzzer starts to pipe and reminds operator at this time, takes remaining positioning pin away, this
Sample, it is ensured that in servo motor starting, cover board is centainly closed with rack backplate, and is not inserted into positioning pin in bolt through-hole, is guaranteed
The normal operation of centrifuge, prevents equipment and personnel from damaging；Conical inclined surface can not only cooperate with bolt through-hole, and lower end surface
