[0046] Specifically, Figure 1-Figure 2 As shown, the front of the grinding device body 1 is connected to a processing table 2, the top of the processing table 2 is rotatably connected to a turntable 3, the bottom of the turntable 3 is installed with a motor, the motor can control the rotation of the turntable 3, so that the staff can stay away from the working area of ​​the grinder 6 to ensure the safety of the staff, the top of the turntable 3 is fixedly connected to two locking clamps 4, the inside of the two locking clamps 4 are placed with a lining body 5, and the front of the mounting plate 706 is fixedly connected to a grinding sheet 8.

[0047] Among the above-mentioned components, the processing table 2 can be used to place the locking clamp 4 and the lining body 5. When the staff needs to grind the inner arc surface of the lining body 5, the staff can operate the locking clamp 4 to clamp the lining body 5, and then the staff can rotate the turntable 3, rotate the turntable 3 close to the inner side of the grinder 6, and then grind the inner arc surface of the lining body 5.

[0048] Specifically, Figure 3-Figure 4 As shown, a transmission shaft 10 is installed on the front of the grinder 6 , one end of the transmission shaft 10 is fixedly connected to a transmission block 702 , and a side wall of the transmission block 702 is fixedly connected to a limiting plate 703 .

[0049] In the above components, the transmission shaft 10 is used to drive the transmission block 702 to provide transmission force for the grinding disc 8, and the transmission plate 701 can be connected through the limit plate 703, so that the connecting plate 707 can be synchronously transmitted.

[0050] Specifically, Figure 4-Figure 8 As shown, one end of the limiting plate 703 is fixedly connected to the inner side of the connecting plate 707 , the other end of the limiting plate 703 is slidably connected to the limiting track 709 , and the locking pin 714 is slidably connected to the inner wall of the limiting track 709 .

[0051] In the above-mentioned components, there is damping at the connection between the locking pin 714 and the limiting track 709, which is not adjusted manually and will not slide by itself. The other end of the limiting plate 703 is limited at the sliding connection with the limiting track 709, which can be coordinated with the buffer spring 705. When the grinding disc 8 is grinding, there is a certain amount of movable space between the limiting plate 703 and the limiting track 709, which can avoid excessive hard contact force between the grinding disc 8 and the lining body 5.

[0052] Specifically, Figure 4-Figure 8 As shown, a locking hole 715 is formed at the top of the locking pin 714 , and one end of the locking rod 708 passes through the mounting plate 706 and is inserted into the locking hole 715 .

[0053] In the above components, the locking rod 708 passes through the mounting plate 706 and is inserted into the locking hole 715, which can firmly fix the locking pin 714 to prevent the locking pin 714 from being displaced from the locking groove 704, thereby keeping it stable.

The bottom end of the transmission handle 713 matches the size of the mounting groove 711 .

[0055] In the above-mentioned components, the mounting groove 711 is used to store and lock the transmission handle 713, which can prevent the transmission handle 713 from being disengaged during the rotation of the transmission shaft 10. There is a large damping at the sliding connection between the transmission handle 713 and the transmission plate 701. When the transmission handle 713 rotates, it can drive the transmission plate 701 to rotate. The transmission plate 701 can drive the limiting column 710 to rotate through the sliding groove 712. When the limiting column 710 rotates, it can push the locking pin 714 to move out of the limiting track 709.

[0056] Specifically, Figure 7 and Fig. 9 As shown, one end of the handle 905 passes through the baffle 903 , a scale plate 911 is fixedly connected to the top of the handle 905 , and an indicator plate 910 is fixedly connected to the front of the baffle 903 .

[0057] In the above components, the staff can more intuitively obtain the thickness of the grinding sheet 8 through the positional relationship between the scale plate 911 and the indicator plate 910. If the grinding sheet 8 is thin, the staff can replace the grinding sheet 8 in time to avoid affecting the grinding work.

[0058] Specifically, Figure 7 and Fig. 9 As shown, a connecting hose 908 is fixedly connected to the bottom end of the water storage box 902 , and the bottom end of the connecting hose 908 passes through the top end of the baffle 903 and the top end of the limiting member 906 in sequence, and is threadedly connected to the cleaning wipe plate 907 .

[0059] Among the above components, the connecting hose 908 has a certain elasticity, and the connecting hose 908 can transmit the cleaning liquid in the water storage box 902. On the one hand, it can clean the impurities on the surface of the grinding plate 8, and on the other hand, it can cool the grinding plate 8.

[0060] Specifically, Figure 7 and Fig. 9 As shown, the valve 904 is installed in the middle of the connecting hose 908 , one end of the valve 904 passes through the water storage box 902 , and the limiter 906 is slidably connected to the inner wall of the top end of the baffle 903 .

[0061] In the above components, when the grinding work stops, the staff can open the valve 904, so that the cleaning liquid in the valve 904 enters the interior of the cleaning wipe plate 907 from the connecting hose 908 and soaks the cleaning wipe plate 907. The limiter 906 can provide limitation and support for the cleaning wipe plate 907.

[0062] Specifically, Figure 1-Figure 4 As shown, a mounting frame 901 is fixedly connected to the top of the baffle 903 , and one end of the mounting frame 901 is fixedly connected to the front side of the grinder 6 .

[0063] Among the above components, the baffle 903 can prevent debris from splashing during cutting, and the mounting frame 901 is made of stainless steel and can provide support for the baffle 903 .

[0064] When the staff needs to replace the grinding disc 8, the staff will set the mounting plate 706 on the outside of the transmission plate 701, and then the staff can turn the transmission handle 713, and the transmission handle 713 drives the transmission plate 701 to rotate. As the transmission plate 701 rotates, the slide groove 712 opened at the top of the transmission plate 701 can drive the limiting column 710 to slide. When the limiting column 710 slides, it can drive the locking pin 714 to slide out of the limiting track 709, and the locking pin 714 is inserted into the locking groove 704 opened on the inner side of the mounting plate 706. As the locking pin 714 is inserted into the locking groove 704, the locking pin 714 can squeeze the locking rod 708. When the locking rod 708 is squeezed, the buffer spring 705 is squeezed. When the locking pin 71 When the locking hole 715 on the outside is at the same position as the locking rod 708, the buffer spring 705 pushes the locking rod 708 to be inserted into the locking hole 715, thereby locking the locking pin 714. The staff can then press the transmission handle 713 to press the transmission handle 713 into the installation groove 711, and the transmission handle 713 can be limited and stored to complete the rapid installation and locking of the grinding sheet 8. The operation is simple and efficient, and the replacement efficiency is improved. It can adapt to grinding sheets 8 of various specifications, and provides convenience for the processing of lining bodies 5 of different models. When the staff grinds the lining body 5, the buffer spring 705 is set. During the grinding process, the buffer spring 705 can provide a certain buffering effect to prevent the grinding sheet 8 from colliding with the lining body 5 Excessive impact contact can effectively prevent wear or damage caused by excessive impact force. At the same time, the buffer design also significantly improves the smoothness and processing quality of grinding, which not only protects the lining and grinding sheet 8, reduces the wear of the equipment under high-intensity work, but also extends the service life of the grinding sheet 8, thereby reducing maintenance and replacement costs. When the staff needs to clean the grinding sheet 8, the staff pushes the handle 905, and the handle 905 drives the limiter 906 to move. When the limiter 906 moves, it can drive the cleaning wiper 907 to fit the surface of the grinding sheet 8. Then the staff can open the valve 904, and the cleaning liquid inside the valve 904 will infiltrate the cleaning wiper 907 through the connecting hose 908. The staff can rotate the grinding sheet 8, and as the grinding The cleaning plate 907 can effectively wipe the debris and dirt on the surface of the grinding plate 8 and keep the grinding plate 8 clean, thereby extending its service life and improving work efficiency. In addition, when the staff pushes the handle 905 again, the staff can judge the thickness of the grinding plate 8 according to the position between the indicator plate 910 and the scale plate 911. If the grinding plate 8 is thin, the staff can replace the grinding plate 8 in time to avoid the efficiency reduction or the influence on the grinding quality caused by the excessive wear of the grinding plate 8. The present invention realizes the rapid installation and locking of the grinding plate 8 by setting the installation buffer mechanism 7. The operation is simple and efficient, the replacement efficiency is significantly improved, and it can adapt to grinding plates 8 of various specifications.It provides great convenience for the processing of linings of different models. During the grinding process, the buffer spring 705 provides an effective buffering effect, avoiding the wear or damage of the grinding sheet 8 and the lining body 5 due to excessive impact, greatly improving the grinding stability and processing quality. At the same time, the buffer design not only protects the lining and the grinding sheet 8, reduces the wear degree of the equipment under high-intensity work, but also prolongs the service life of the grinding sheet 8, thereby effectively reducing the maintenance and replacement costs, and further improving the working efficiency and economy of the equipment.
