[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes an apparatus for fabricating different structural surfaces on a rock sample, including a desktop frame 1, a positioning mechanism 2 for adjusting the position at the top of the desktop frame 1, a water jet mechanism 3 for cutting the rock sample at the top of the desktop frame 1, a turntable assembly 4 for rotating the rock sample at the top of the desktop frame 1, a water collection assembly 5 for collecting cutting debris at the bottom of the desktop frame 1, and a water pressure control assembly 6 for adjusting the water jet pressure on one side of the water jet mechanism 3.

[0029] like Figure 2 and Figure 4As shown, the positioning mechanism 2 includes slide rails 201 mounted on the top of the desktop frame 1. Retractable support rods 202 are installed inside the two slide rails 201, and are slidably connected to the slide rails 201. A horizontal laser marker 203 is mounted on the side wall of the retractable support rod 202. A crossbeam 204 is installed between the two retractable support rods 202. A scale 205 is mounted on the top of the desktop frame 1. A pointer 206 is mounted on the side wall of the retractable support rod 202. The side walls of the two retractable support rods 202 are threaded together. With locking bolts 207, the bottom of the desktop frame 1 is equipped with support legs 208. The four support legs 208 are evenly distributed. Through the cooperation of slide rail 201, telescopic support rod 202, scale 205, pointer 206 and locking bolts 207, the position of telescopic support rod 202 can be precisely adjusted to meet the positioning requirements of rock samples of different sizes. The transverse laser marker 203 helps to more accurately determine the starting position of cutting, improves positioning accuracy, and effectively controls positioning error, providing a guarantee for subsequent accurate cutting of rock samples. In use, the slide rail 201 provides a sliding track for the telescopic support rod 202, allowing it to move laterally on the top of the desktop frame 1. The telescopic support rod 202 itself can be adjusted in length. The horizontal laser marker 203 emits a horizontal laser line for positioning. The scale 205 and pointer 206 work together to visually read the moving position of the telescopic support rod 202. The locking bolt 207 is used to fix the position of the telescopic support rod 202 on the slide rail 201 to prevent it from moving arbitrarily.

[0030] like Figure 3As shown, the waterjet mechanism 3 includes a moving device 301 slidably connected to the crossbeam 204. The top of the moving device 301 is provided with a water inlet connector 302. A nozzle 303 is connected to the side of the water inlet connector 302 near the desktop frame 1, and a water inlet pipe 304 is connected to the side of the water inlet connector 302 away from the desktop frame 1. A vertical line laser marker 305 is fixedly connected to the bottom of the moving device 301. The moving device 301 slides on the crossbeam 204, which can flexibly adjust the cutting position and expand the cutting range. The waterjet cutting method uses a mixture of high-pressure water and sand. Compared with the traditional cutting method, it has the advantages of high cutting accuracy, flat cutting surface, and no heat-affected zone. It can better create structural surfaces on rock samples. The vertical line laser marker 305 and the horizontal line laser marker 203 are cross-positioned to further improve the accuracy of the cutting position. In use, the moving device 301 can slide on the crossbeam 204, driving the inlet connector 302, nozzle 303 and inlet pipe 304 to move. The inlet connector 302 is connected to the inlet pipe 304 to introduce the mixture of high-pressure water and sand, which is then sprayed out through the nozzle 303 to form a high-pressure water jet to cut the rock sample.

The third gear 405 passes through the desktop frame 1 and is fixedly connected to the rotating disk 401. The top of the rotating disk 401 is provided with a sliding groove 407, and four movable fixing blocks 408 are disposed inside the sliding groove 407. In use, the rotating disk 401 is used to place the rock sample; the knob 406 rotates to drive the first gear 403 to rotate, and the first gear 403 transmits power to the third gear 405 through meshing with the second gear 404 and the third gear 405. The third gear 405 drives the rotating disk 401 to rotate, thereby realizing the rotation of the rock sample. The arc-shaped drainage groove 402 is used to drain the water and debris generated during the cutting process. The sliding groove 407 and the movable fixing block 408 are used to fix rock samples of different sizes to prevent them from moving during rotation.

[0032] like Figure 3As shown, the water collection assembly 5 includes a water collection tank 501 located at the bottom of the desktop frame 1, with a drain pipe 502 connected to the side wall of the water collection tank 501. In use, the water collection tank 501 is positioned at the bottom of the desktop frame 1 to collect water and debris generated during the cutting process. The drain pipe 502 connects to the water collection tank 501, discharging the collected water and debris outside the device, effectively collecting the cutting debris and wastewater and preventing them from scattering in the working environment.

[0034] like Figure 5 As shown, the first gear 403, the second gear 404, and the third gear 405 are spur gears with a module of 2mm and a gear ratio of 2:1:2. The first gear 403, the second gear 404, and the third gear 405 are driven by meshing, with an adjustment accuracy of ≤0.5°. In use, the first gear 403 rotates under the influence of the knob 406, transmitting power to the second gear 404 through meshing. The second gear 404 then meshes with the third gear 405, transmitting power to the third gear 405. The third gear 405 drives the rotating disk 401 to rotate, achieving a specific transmission ratio and speed conversion according to the gear gear ratio.

[0035] like Figure 2 and Figure 3 As shown, the horizontal line laser marker 203 and the vertical line laser marker 305 are intersected for positioning, with a positioning error ≤0.1mm. In use, the vertical line laser marker 305 and the horizontal line laser marker 203 are intersected for positioning, further improving the accuracy of the cutting position.

[0036] Specifically, in use, the device for fabricating different structural surfaces on rock samples works as follows: The slide rail 201 provides a sliding track for the telescopic support rod 202, allowing it to move laterally on the top of the desktop frame 1. The telescopic support rod 202 itself can be adjusted in length. The horizontal laser marker 203 emits a horizontal laser line for positioning. The scale 205, in conjunction with the pointer 206, allows for direct reading of the telescopic support rod 202's position. The locking bolt 207 is used to fix the telescopic support rod 202's position on the slide rail 201, preventing it from moving arbitrarily (e.g., ...). Figure 2 and Figure 4As shown), the moving device 301 can slide on the crossbeam 204, driving the inlet connector 302, nozzle 303, and inlet pipe 304 to move. The inlet connector 302 is connected to the inlet pipe 304, introducing a mixture of high-pressure water and sand, which is then sprayed out through the nozzle 303, forming a high-pressure water jet to cut the rock sample. The vertical line laser marker 305 emits a vertical laser line, which intersects with the horizontal line laser marker 203 of the positioning mechanism 2 to determine the cutting point (e.g., ...). Figure 3 As shown), the water collection tank 501 is located at the bottom of the desktop frame 1 to collect water and debris generated during the cutting process. The drain pipe 502 is connected to the water collection tank 501 to discharge the collected water and debris outside the device, effectively collecting the cutting debris and wastewater and preventing them from scattering in the working environment (such as...). Figure 3 As shown), control cabinet 601 controls the delivery of high-pressure water and sand through high-pressure water conduit 602 and sand conduit 603 respectively, thereby adjusting the water pressure and sand flow rate ejected from nozzle 303 in waterjet mechanism 3 to meet the waterjet cutting parameters under different rock sample and cutting requirements (such as...).
