Problems solved by technology

[0005] At present, most rock sample grinding machines can only grind one end face of the rock sample at a time, and the length of the rock sample needs to be measured manually, and there are repeated procedures of loading and unloading the rock sample during the grinding process. First, the efficiency is low, and the second is the accuracy. High, the third is time-consuming and labor-intensive

Embodiment Construction

[0019] A rock sample double-end grinding machine provided by the present invention has specific working steps as follows:

[0020] Step 1: Place the rock sample to be polished horizontally between the upper and lower compression rods, and tighten the adjusting bolts so that the rock sample is fixed by the compression rod. Through the final retained rock sample length L 0 The distance from the end face of the grinding disc on both sides to the inner end face of the electric control cabinet is 2L 1 sum to determine the scale value L of the length control ruler 2 (ie: L 2 =L 0 +2L 1 ), extend the length control ruler out of the ruler slot to the scale value L 2 .

[0021] Step 2: Start the grinding machine, the clamping table is fed back and forth through the slide rails, and the two electric control cabinets control the racks on both sides to automatically approach the rock sample. Manually, it is realized by rotating the rings on both sides, and the grinding disc starts t...

Abstract

The invention discloses a rock sample double-end surface grinder. The rock sample double-end surface grinder comprises a base, frames, electrical cabinets and a clamping bench. The base is rectangular and is arranged at the bottom of the rock sample double-end surface grinder. The two frames are movably connected to the base through driving elements, are respectively located at left and right ends of the base and are perpendicular to the base. The two electrical cabinets are respectively arranged at left and right sides of the upper parts of the two frames. Two ends of the inner sides of the two electrical cabinets are respectively and symmetrically provided with two circular polishing discs. The clamping bench is slidingly connected to the base through a sliding rail installed above the base. The sliding rail is located at the axisymmetric center of the base. A rock sample is polished simultaneously through double end surfaces so that artificial measurement-caused errors are avoided and repeated processes of rock sample loading and unloading and time waste are avoided. The rock sample double-end surface grinder has the advantages of high polishing efficiency, accurate and reliable length control and operation convenience.

Description

【Technical field】 [0001] The invention belongs to the field of rock mechanics tests, in particular to a rock sample double-end grinding machine. 【Background technique】 [0002] Rock mechanics test is the basis of rock mechanics research. Although rock mechanics has made great progress and development in scientific calculation, theoretical analysis, numerical simulation, etc., rock mechanics test still plays a key role in directly solving practical engineering problems. Irreplaceable. [0003] With the rapid development of economy and society, some large-scale and super-large civil projects have emerged, which inevitably involve many complex rock mechanics problems, and put forward higher requirements for rock mechanics tests. As we all know, in rock mechanics tests, mechanical parameters such as uniaxial compression, tensile strength, elastic modulus, Poisson's ratio, cohesion and internal friction angle of standard rock samples are obtained through tests, and the obtained ...
