[0032] Embodiment 1

[0033] In one embodiment of the present invention, please refer to Figure 1-7, an intelligent pressing device for a grinding and polishing machine and its usage method, comprising a base 1, a base column 2 disposed above the middle of the base 1, and a pressing mechanism 3 rotatably connected to the top of the base column 2; the pressing mechanism 3 includes a control head 301, a rotating head 302, and a fixing disk 303. One end of the control head 301 is rotatably connected to the top of the base column 2, and the other end is rotatably connected to the top of the rotating head 302. A first telescopic member 304 for controlling the lifting of the fixing disk 303 is disposed between the fixing disk 303 and the rotating head 302. One end of the first telescopic member 304 is fixedly connected to the center of the fixing disk 303, and the other end is fixedly connected to the center of the rotating head 302; a plurality of sample slots 307 for storing samples are formed in the fixing disk 303. In this embodiment, four sample slots 307 are formed. The four sample slots 307 are circumferentially and evenly distributed around the axis of the fixing disk 303. The connection line between the centers of adjacent sample slots 307 and the center of the fixing disk 303 forms a 90° angle. Bolts 308 for locking the samples are respectively disposed at the bottoms of the sample slots 307. A laser leveling instrument 309 is further disposed at the bottom of the side wall of the fixing disk 303; two grinding and polishing disks 4 are symmetrically disposed on the left and right sides of the middle of the base 1, and an unloading disk 5 is disposed at a position slightly lower than the middle of the base 1. A plurality of screwdrivers 6 for controlling the tightening or loosening of the bolts 308 are circumferentially and evenly disposed on the inner circumference of the side wall of the unloading disk 5. In this embodiment, the number of screwdrivers 6 is 4 and they are matched with the bolts 308; second telescopic members 305 are respectively disposed between the rotating head 302 and the sample slots 307. The second telescopic members 305 extend into the sample slots 307. A plurality of third telescopic members 306 are disposed at the bottoms of the second telescopic members 305. In this embodiment, the number of third telescopic members 306 at the bottoms of the second telescopic members 305 is three, and they are circumferentially and evenly distributed around the axis of the second telescopic member 305. In this embodiment, a computer, a controller, and a battery pack for controlling the operation of the device are disposed in the base 1, and corresponding control buttons 9 and a liquid crystal display screen 10 are disposed on the control head 301. A radio frequency device is disposed in the laser leveling instrument 309. The first telescopic member 304, the second telescopic member 305, and the third telescopic member 306 are all hydraulic lifting rods. A collection channel 7 for collecting finished products is connected to the bottom of the unloading disk 5, and a retractable door 8 for controlling the opening or closing of the collection channel 7 is provided. A dust-proof cover is disposed outside the control head 301.

[0034] When using this device, first perform the sample loading process. The staff first place four groups of samples into the four sample slots 307 from the top of the fixed disk 303, with four samples in each group. Then, control the operation of this device through the control buttons 9 on the control head 301. This device controls the control head 301 to rotate around the axis of the base column 2 through the controller and reach above the unloading disk 5 preset by the computer. Then, control the first telescopic member 304 and the second telescopic member 305 to extend synchronously through the controller, so that the height of the fixed disk 303 decreases until the bottom of the fixed disk 303 almost touches the surface of the retractable door 8 at the bottom of the unloading disk 5, and then stop extending. At this time, the retractable door 8 provided on the collection channel 7 is in a closed state. Then, control the four second telescopic members 305 to continue extending, press the samples in the sample slots 307, so that the bottom surface of the bottommost sample touches the surface of the retractable door 8 at the bottom of the unloading disk 5. At this time, control the screwdriver 6 in the side wall of the unloading disk 5 to extend out through the controller until it contacts the bolt 308, and then the screwdriver 6 starts to rotate forward to tighten the bolt 308, so that the bottommost sample in the sample slot 307 is fixed at the bottom of the fixed disk 303. Then, the screwdriver 6 retracts, and the sample loading process is completed. Then, start the grinding and polishing process of the sample. Control the first telescopic member 304 and the second telescopic member 305 to shorten synchronously through the controller, so that the fixed disk 303 moves away from the unloading disk 5. Then, rotate the control head 301 so that the fixed disk 303 is located above the grinding and polishing disk 4. At this time, start the grinding and polishing disk 4. The first telescopic member 304 and the second telescopic member 305 extend synchronously under the control of the computer, so that the bottom surface of the sample fixed at the bottom of the fixed disk 303 contacts and presses the grinding and polishing disk 4, and start grinding and polishing. During the entire grinding and polishing process, the laser flatness gauge 309 real-time online checks the flatness of the polished sample, and sends the signal feedback to the controller through the radio frequency device provided in the laser flatness gauge 309. The controller converts the actual angle value analog signal into an electrical signal after processing and outputs it to the liquid crystal display screen 10. When the flatness error exceeds the set value, the controller transmits the signal to the pressing mechanism 3. The controller analyzes the uneven positions on the surface of the sample according to the size of the inclination angle, and increases or decreases the pressure on the sample by the three third telescopic members 306 above each sample until the flatness is 0°. At this time, the sample grinding and polishing process is completed;Next, start the process of specimen detachment and collection. Control the three third telescopic members 306 at the bottom of each second telescopic member 305 to return to the initial same position. Then, the second telescopic member 305 and the first telescopic member 304 contract, driving the upper body of the fixed disk 303 away from the grinding and polishing disk 4. Next, control the rotation of the control head 301 so that the fixed disk 303 is located above the unloading disk 5. Then, control the first telescopic member 304 and the second telescopic member 305 to extend synchronously until the bottom of the fixed disk 303 is lowered to almost contact the surface of the retractable door 8 at the bottom of the unloading disk 5 and then stop extending. At this time, open the retractable door 8, and then control the screwdriver 6 to extend until it contacts the bolt 308. Then, the screwdriver 6 starts to reverse to loosen the bolt 308, causing the specimen at the bottom of the specimen groove 307 to detach from the fixed disk 303 and fall into the collection channel 7 for the finished specimen to collect the finished specimen, completing the process of specimen detachment and collection; Next, start the process of specimen replacement. After controlling the retractable door 8 to close, then control the second telescopic member 305 to extend, pressing down the unprocessed specimen in the specimen groove 307 so that the bottom of the lowermost specimen contacts the surface of the retractable door 8 at the bottom of the unloading disk 5. At this time, control the screwdriver 6 in the side wall of the unloading disk 5 to extend until it contacts the bolt 308 through the controller, and then the screwdriver 6 starts to rotate forward to tighten the bolt 308, fixing the lowermost specimen in the specimen groove 307 to the bottom of the fixed disk 303. Then, the screwdriver 6 retracts, and the specimen replacement process is completed; Then, continuously repeat the above specimen grinding and polishing process, specimen detachment and collection process, and specimen replacement process until all the specimens in the specimen groove 307 are ground and polished. At this time, the staff starts the specimen loading process again, and then repeats the above steps.;

[0035] In this embodiment, the staff only needs to load the specimen after all the specimens in the specimen groove 307 are ground and polished each time. The rest of the process is controlled by the computer through the controller. The flatness of the specimen is detected in real time by the laser leveling instrument 309, and then the force applied to the specimen is adjusted by controlling the first telescopic member 304, the second telescopic member 305, and the third telescopic member 306 to make the flatness of the specimen close to 0°. This not only improves the flatness of the specimen surface and reduces the influence on the subsequent observation of the metallographic structure, but also has a high degree of automation.
