9. being used for the automatic detection device of cylindrical rock sample as claimed in claim 6, which is characterized in that the turntable
Ball including turntable outer ring, turntable inner ring, and between turntable inner ring and turntable outer ring, turntable outer ring and turntable inner ring
It relatively rotates；The bottom of the turntable has magnetic limiting plate, and magnetic limiting plate is locked with the iron baffle absorption on pedestal；
The iron baffle includes iron baffle one and iron baffle two, and iron baffle one and iron baffle two are located at where the diameter of a circle of turntable bottom surface directly
On line.
10. a kind of cylindrical rock sample automated detection method, which is characterized in that include the following steps：
Step 1: providing automatic detection device described in claim 1；
Step 2: the sample marking line by sample pedestal positions rock sample, ensure the lower face circle of rock sample
The heart is overlapped with the center of sample area；
Step 3: synchronous push two clamp systems to fix rock sample；
Step 4: spinning sample pedestal, makes the magnetic limiting plate on pedestal be fixed with the absorption of irony baffle one, records sample pedestal
On weighing instrument reading；
Step 5: the rectangular magnetic suction base correspondence in track both ends is positioned at the top of perpendicular side plate unit A and perpendicular side plate unit B
Groove in, and by magnetic suction base by sliding platform unit adsorb fix；
Step 6: by control processor synchronous averaging push rod A, push rod B and push rod C, and measured by laser displacement sensor A
The outer wall of rock sample is measured to the distance of perpendicular side plate unit A, the outer wall of rock sample is measured by laser displacement sensor B
To the distance of perpendicular side plate unit B, rock sample top end surface and sliding test platform list are measured by laser displacement sensor C
The distance of member；Control processor receives above three groups of range data and analyzing processings, obtains the diameter of rock sample and relatively high
Spend parameter；
It is analyzed Step 7: being calculated by control processor, obtains the verticality parameter of rock sample；
Step 8: by the angle of sample pedestal rotation setting, step 5~step 7 is repeated；
Step 9: the 8th step is repeated, until magnetic limiting plate is fixed with the absorption of irony baffle two；
Step 10: control processor makes each push rod reset, each laser displacement sensor is closed；
Step 11: control processor is by the flatness of the above parameter detecting rock sample, the depth of parallelism, verticality index and obtains
It is fitted to density parameter, while based on data are measured, establishes the three-dimensional model of rock sample.
