Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.

[0034] Such as Figure 1-2 As shown, the present invention provides a kind of clamping device in the standard sample processing process, and it comprises screw rod, nut and fixing device 14, and described screw rod and nut altogether eight sets, wherein, the diameter of four sets of described screw rod and nut is 12mm, and the diameter of the other four sets is 16mm. The fixing device is a cuboid structure processed by a cylindrical nylon rod. The fixing device made in this way has good toughness, strong wear resistance, oil resistance, shock resistance, stretching, Good bending strength, low water absorption, good dimensional stability, etc., a cylindrical hole 9 with...

Abstract

The invention provides a tightly holding device in a standard sample machining process. The tightly holding device comprises screw rods, nuts and a fixing device; eight sets of screw rods and nuts are provided, wherein four sets have diameters of 12 mm, and the other four sets have diameters of 16 mm; the fixing device is formed by machining a cylindrical nylon rod, and a cylindrical hole with a diameter of 62.5 mm is machined in middle through a lathe for tightly holding a cylindrical sample to be machined; the fixing device has four small cylindrical holes with diameters of 12 mm and with a fixing effect on the fixing device; the fixing device is additionally provided with four large cylindrical holes with diameters of 16 mm; and the four large cylindrical holes with the diameters of 16 mm achieve a fixing effect on the fixing device and a drill base. The tightly holding device in the standard sample machining process has such advantages as high working efficiency, low workload, simple operation and high sample sampling efficiency.

Description

technical field [0001] The invention relates to the technical field of rock core standard sample processing, in particular to a clamping device during standard sample processing, and belongs to the technical field of coal mining. Background technique [0002] In the process of coal mining, the overlying strata can be divided into caving zone, fissure zone and curved subsidence zone from bottom to top. Studying the movement laws of the overlying strata helps to understand the mechanism of roof fracture, initial compression, periodic compression, flaking and roof cutting. The basic mechanical properties of the overlying strata are the basis for understanding the movement laws of the overlying strata. In order to understand the rock mechanical properties of the overlying rock, cores are generally taken by drilling. By processing the core, the core is processed into a standard sample with a diameter of 50mm and a height of 100mm for uniaxial compression test and triaxial compr...
