Sample fixture used for rock cutting machine

Abstract

The invention relates to a sample fixture used for a rock cutting machine. The sample fixture comprises a positioning frame, a fixing block, an L-shaped graduated scale and bolts, wherein the outer side of the positioning frame is provided with a trapezoidal groove, and the lower side of the inner part is provided with a V-shaped rock clamping groove; the fixing block is arranged in the positioning frame; one side surface of the fixing block is provided with bolt holes which are consistent with the top of the positioning frame and are not penetrated, and the other side surface is provided witha V-shaped clamping groove symmetric with the V-shaped clamping groove in the positioning frame; the graduated part of the L-shaped graduated scale is trapezoidal, an extension part is positioned onthe end part of the graduated part and is vertical to the end part of the graduated part, and the L-shaped graduated scale is arranged in the outer side trapezoidal groove of the positioning frame; the positioning frame and the fixing block are connected through the bolts; and the positioning frame is fixed on a cutting table in a way that the bolts penetrate through the bolt holes on the base. Byuse of the sample fixture, the rock sample is horizontally and firmly fixed on the cutting table, the levelness and flatness requirements of the rock sample as well as the safety of a cutting processare guaranteed, the L-shaped graduated scale can observe the scale while the rock sample is cut, and the cutting accuracy and convenience of the rock sample can be guaranteed.

Description

Technical field [0001] The invention relates to a sample holder for a rock cutting machine. Background technique [0002] In rock-related tests, it is often necessary to cut the drilled rock rods according to the size required by the test. The rock cutter is a commonly used cutting machine in the processing of rock samples. It is necessary to use different clamping methods to fix the rock samples firmly according to the shape of the rock, otherwise it will not only affect the cutting of the sample, but even cause safety problems. The rock cutting machine itself is not equipped with a fixture specially used to fix the rock sample, which causes certain problems in the cutting of the rock sample. Therefore, the firm fixation of the rock sample during the cutting process becomes a problem that must be solved. In addition, when cutting a rock sample of a specified size, it is necessary to manually mark the measured size of the drilled rock rod before cutting. The process is cumbersom...

AI Technical Summary

Problems solved by technology

The rock cutting machine itself is not equipped with a special fixture for fixing rock samples, which causes some troubles to the cutting of rock samples. Therefore, the firm fixing of rock samples during the cutting process has become a problem that must be solved

In addition, when cutting a rock sample of a specified size, it is necessary to manually mark the measured size of the drilled rock rod and then cut it. Therefore, it is an important requirement in rock cutting to be able to view and adjust the cutting length conveniently and accurately
