The machine can freely move along the three-axis direction, and the angle is adjusted; the requirements of processing a test piece of the international rock fracture toughness test standard are met; the device has the advantages of reasonable structure, good performance, high precision and convenient use.
Description
The present invention relates to tester, especially for the process equipment of the rock sample crackle opening of rock fracture toughness method of testing.
The accurate mensuration of rock fracture toughness is very important basic work in the rock fracture mechanics, yet, finish this work, the processing request that can the process equipment of its rock sample satisfy international rock fracture toughness testing standard test specimen is a key.The present rock sample process equipment that uses, normally only can make the general cutting machine of horizontal resection motion, can not satisfy conventional rock sample processing, comprise that rock core drills through and straight cuts and grinding, be difficult to reach the requirement of rock fracture toughness method of testing standard specimen processing dimension; Can't carry out especially for the crackle processing of fragile material fracture specimen and the processing of other special-shaped test specimen.
The objective of the invention is to overcome the weak point of existing device, and manufacture and design a kind of conventional rock sample processing criterion that not only can reach, and satisfy fragile material test specimen and the processing of other special-shaped test specimen, the rock sample processing machine of requirement.
The present invention has manufactured and designed a kind of multifunctional rock test specimen processing machine for achieving the above object, and it is characterized in that: the head 15 on support 1 top, one end are equipped with by the governor motion 4 of handle 10 regulation and control and the knife rest 7 that motor and saw blade are housed are being set; In the bottom of support 1 vertical lifting mechanism of being handled by handwheel 14 3 is installed, is provided with travel mechanism 5 in length and breadth on it, connecting the workbench 2 that test specimen 9 anchor clamps 8 are installed by angular transition mechanism 11.
Remarkable advantage of the present invention is: workbench 2 not only can move freely along three direction of principal axis, and can adjust angle.Thereby make the cutting and the flat stone mill of perpendicular cuts and end face mill and translation-angle on rock sample processing machine of the present invention, to finish, satisfied the requirement of international rock fracture toughness testing standard test specimen processing dimension fully, see Table 1.
