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.
