Problems solved by technology

During the working process of the double-end stone grinder, the end of the cooling water pipe is fixed on the fixture, and the fixture reciprocates along with the worktable of the stone grinder, so the cooling water pipe is easily damaged; when the cooling water pipe reciprocates on the workbench When it is used, it is prone to water splashing, low utilization rate and waste of cooling water, and pollutes the laboratory environment

Abstract

The invention relates to a hollow self-cooling grinding disc, wherein the middle part of the grinding disc is a hollow structure, and a cooling water pipe is arranged in the hollow structure, which improves the utilization rate of the cooling water, prolongs the service life of the cooling water pipe, and realizes self-cooling of the grinding disc. The inner side of the grinding disc surface is set as a circular arc concave surface, and the outer side of the grinding disc head is provided with a circular arc concave baffle to ensure that the cooling water is sprayed and reflected on the grinding disc, and under the action of centrifugal force, the cooling water can be efficiently cooled. A retractable transparent plexiglass cover is placed above the grinding table, which can not only ensure that the working status of the grinding table can be seen, but also avoid the short circuit phenomenon of the instrument and personal injury caused by water splashing. The cover is retractable in the direction of the motor shaft, which is convenient for testers to place and take out samples.

Description

technical field [0001] The invention relates to the field of geotechnical engineering instruments, which belongs to a rock sample processing tool, in particular to a hollow self-cooling grinding disc for grinding rock samples, and also relates to a self-cooling method for the grinding disc. Background technique [0002] Laboratory test is a basic method commonly used in the field of geotechnical engineering to study geotechnical properties. The processing of rock samples is the basic step in carrying out various rock tests. The smoothing of both ends of the rock after coring is the basis for the smooth progress of subsequent rock mechanics tests and the prerequisite for obtaining accurate test data. [0003] The flattening instrument of existing rock sample mainly divides two kinds of single-side grinder and double-end grinder. During the working process of the double-end stone grinder, the end of the cooling water pipe is fixed on the fixture, and the fixture reciprocates...
