Crashing-preventing type rock sample cutting and grinding device and cutting and grinding process thereof

Abstract

The invention relates to a crashing-preventing type rock sample cutting and grinding device and a cutting and grinding process thereof, wherein a motor of the crashing-preventing type rock sample cutting and grinding device drives two parallel transmission shafts, one is provided with a diamond cutting piece, the other one is provided with a grinding wheel, and a clamping device is opposite to the diamond cutting piece and the grinding wheel; a feeding device can run along a base so as to adjust the positions between the clamping device and the diamond cutting piece, and between the clamping device and the grinding wheel; the clamping device is provided with a holder that penetrates from a bracket, the holder is split, an upper holding body and a lower holding body are buckled to form a cylindrical holding cavity, the upper holding body is provided with a clamping rocking handle which is in threaded connection with the upper holding body by penetrating through the bracket, a cooling pipe is arranged on the holder, and a nozzle of the cooling pipe is arranged in front of the holding cavity. The crashing-preventive type rock sample cutting and grinding device integrates cutting and grinding, and the problem that a rock sample is easy to be clamped to be crashed is solved, the operation is simple and convenient and successful rate is high.

Description

1. Technical field: [0001] The present invention relates to a rock mechanics sample preparation tool mainly used in the fields of rock mechanics engineering, rock and soil mechanics engineering, petroleum engineering and mining engineering, and specifically relates to an anti-fragmentation rock sample cutting and grinding device and its Cutting process. 2. Background technology: [0002] In order to understand the physical and mechanical properties of surface and deep underground rocks, scholars in the fields of rock mechanics engineering, geotechnical mechanics engineering, petroleum engineering and mining engineering conduct a large number of rock mechanics experiments every year. At present, the sample size used in rock mechanics tests at home and abroad is mostly φ25mm*50mm or φ50mm*100mm. Due to the small size of cores taken from deep formations (generally cylindrical cores of φ100mm) and the small number, rock samples of φ25 mm*50mm are commonly used in petroleum engi...
