When the device is fixed inside the roll press, the horizontal position of the device and the roll can be adjusted through the adjustment block 11, and the roll can be directly ground on the roll press, reducing the frequency of removing the roll.

[0026] The transmission group is provided on the chassis 12. The transmission group includes a transmission X-axis 21 and a transmission Y-axis 22. The transmission X-axis 21 is fixed on the transmission Y-axis 22 and is perpendicular to the transmission Y-axis 22. The grinding group 3 is fixed on the transmission X-axis 21. The transmission group can be used for the movement of the grinding group 3 in the X-axis and Y-axis directions.

[0027] The transmission Y-axis 22 includes a Y-axis bottom plate 221, a linear guide rail 223 and a Y-axis screw rod 22,2. One end of the Y-axis bottom plate 221 is provided with a baffle 225. The baffle 225 is provided with a limit block 226 and a Y-axis servo motor 227. The limit block 226 can limit the movement of the transmission X-axis 21 in the Y-axis direction. The Y-axis bottom plate 221 is fixedly arranged on the chassis 12 through screws. The Y-axis screw rod 222 is fixed on the Y-axis bottom plate 221. One end of the Y-axis screw rod 222 passes through the baffle 225 and is fixed on the baffle 225. Linear guide rails 223 are provided on both sides of the Y-axis bottom plate 221. Two first sliders 224 are respectively provided on the linear guide rails 223. The transmission X-axis 21 is fixed on the first sliders 2,24. The transmission X-axis 21 can be driven to move by the Y-axis servo motor 227 and the Y-axis screw rod 222, so as to drive the grinding group 3 to move in the Y-axis direction.

[0028] The driving X-axis 21 includes an X-axis chassis 12, an X-axis servo motor 212, an X-axis slide 213 and a top plate 214. The X-axis chassis 12 is fixedly installed on the first slider 224 by screws. The X-axis servo motor 212 is fixedly installed on the X-axis slide 213.

Among them, before grinding, the slide cylinder 42 can be used to push the mounting plate 41 to extend the detection probe 44 and press it against the roll. As the driving Y-axis 22 moves, the change degree of the roll shape is detected, so as to determine the grinding amount of the roll, and the roll is ground through an automatic control program. The accuracy of the detection probe 44 can reach 0.001 mm.

[0031] On the top of the fixed block 31, a grinding fluid spray head group 5 is further provided. The grinding fluid spray head group 5 includes a spray head base 51 and a spray head 52.

The scraper 64 is arranged in the clamping groove to clean the grinding fluid after polishing. The scraper cylinder 62 is fixedly arranged on the scraper base 61 to drive the scraper fixing plate 63 to eject or retract.

[0033] Further, the wiping roller group 8 is arranged below the chassis 12. A water receiving tray 7 is fixedly arranged below the chassis 12 by screws for collecting the grinding fluid. The wiping roller group 8 includes a wiping roller plate 81, a wiping roller fixing plate 84, a handle 82, a wiping roller cylinder 83 and a wiping roller sliding group. The wiping roller plate 81 is fixedly installed above the wiping roller fixing plate 84. A wiping roller cloth is fixed on the wiping roller plate 81 to remove the residual polishing fluid. The wiping roller cylinder 83 is fixed inside the wiping roller fixing plate 84 to press and retract the wiping roller plate 81 fixed on the wiping roller fixing plate 84. The handle 82 is fixed inside the wiping roller fixing plate 84 to move the whole wiping roller group 8 back and forth.

[0034] The wiping roller sliding group is fixedly arranged outside the wiping roller fixing plate 84. The wiping roller sliding group includes a wiping roller slideway 88, a first wiping roller slider 86, a wiping roller connecting plate 85 and a wiping roller fastening block 87. The wiping roller slideway 88 is fixedly installed below the chassis 12. A first wiping roller slider 86 and a wiping roller fastening block 87 are arranged on the wiping roller slideway 88. A wiping roller connecting plate 85 is fixedly installed below the first wiping roller slider 86. One side of the wiping roller connecting plate 85 is fixedly installed on the wiping roller fixing plate 84. The wiping roller fastening block 87 is installed on the wiping roller slideway 88. The lower part of the wiping roller fastening block 87 is fixedly installed on the wiping roller connecting plate 85 for fixing the position of the wiping roller group 8.

[0035] In the specific implementation of the present invention, the fixing assembly 1 is fixed to the inner gear of the roller press and adjusted to the correct level. When the roller surface is insufficient and requires grinding, the other components are fixed to the fixing assembly 1. Before grinding, the drive Y-axis 22 is moved to the motor end, and the slide cylinder 42 is extended so that the detection probe 44 is pressed against the roller. When the drive Y-axis 22 slowly moves to the end of its travel, the detection probe 44 will detect a roller profile curve. This curve is then compared with the original roller profile curve recorded in the comparison system to determine the difference in roller shape change, thereby controlling the subsequent finishing process. During grinding, the drive X-axis 21 cooperates with the grinding assembly 3 to perform tool alignment. The vibration generator 34 maintains high-frequency vibration, and the grinding head 35 is in contact with the roller. The drive Y-axis 22 is controlled by the program to quickly move and grind the roller. The pressure between the grinding head 35 and the roller must be consistent. This can be achieved through the grinding head 35's built-in pressure sensor and the drive X-axis 21 servo control, or through a pressure sensor and a low-friction cylinder. The grinding liquid is removed by the scraper group 64 and the wiping roller group 8. The scraper group 64 scrapes away most of the grinding liquid into the water receiving tray 7 through the scraper 64, and the remaining grinding liquid is wiped off by the wiping roller cloth on the wiping roller plate 81.

Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
