The invention relates to a fixing device suitable for grinding rock samples with inclined joints, which comprises a fixed platform, a bottom beam is arranged on the surface of the fixed platform, a longitudinal beam plate is vertically installed at one end of the bottom beam, and a screw rod is vertically installed at the other end of the bottom beam. One end of the moving beam is movably connected to the screw rod, and a central groove is opened in the center of the aforementioned longitudinal beam plate, and the other end of the moving beam is movably placed in the center groove, and the basic structure between the moving beam and the bottom beam is also included. Matched and fixed with the bottom beam, the rotating disc for placing the rock sample to be polished can be rotatably connected to the base structure, the angle is set on the base structure, the pointer is installed on the rotating disc, and the pointer matches the angle to determine the joint direction of the rock sample to be polished It also includes a cover structure, which is placed above the rotating disk, and the cover structure clamps the bottom of the rock sample to be polished; the invention overcomes the defects of large errors in the measurement of joint orientation and fixing process in the traditional rock sample preparation process.
Description
technical field [0001] The invention relates to a fixing device suitable for grinding rock samples with inclined joints, and is especially used for fixing samples of double-end grinding stone machines. Background technique [0002] Joints are structural planes that widely exist in nature, and the existence of joint planes affects the mechanical properties of rocks. At the same time, the angle of the joint surface relative to the direction of the force is also an important factor, so the study of jointed rock masses with dip angles is very important for engineering safety design and construction. However, in the process of sample preparation for related mechanical tests, the process of determining the orientation of the internal joints of the rock sample and grinding is very crude. First, a protractor is used to determine the direction, and then it is fixed on a double-end grinder for grinding. Among them, the angle measurement and fixing process will produce large errors, a...
