Description

Technical Field

[0001] The present invention relates to the technical field of wear-resistant lining plate processing devices, and particularly to a wear-resistant lining plate edge grinding device and an edge grinding method thereof. Background Art

[0002] A wear-resistant lining plate edge grinding device is a device specifically used for edge grinding of wear-resistant lining plates. This device usually consists of key components such as a base frame, a control panel, a power cavity, an edge grinding strip, and a wear-resistant lining plate body. During operation, the wear-resistant lining plate is placed at a specific position in the device, and the edge grinding strip is driven by a driving mechanism (such as a bidirectional screw column, a screw cap, and a crank) in the power cavity to precisely grind the edge of the wear-resistant lining plate. This device not only improves the efficiency and accuracy of edge grinding but also ensures the uniformity and consistency of the edge grinding effect.

[0003] For example, the Chinese authorized patent "A Wear-Resistant Lining Plate Edge Grinding Device" with the publication number CN220112926U includes a workbench. The lower surface of the workbench is fixedly connected with support legs. Between the two inner walls of the workbench, a first limiting plate is fixedly connected. The upper surface of the first limiting plate is provided with a first limiting groove. Between the two inner walls of the workbench, a second limiting plate is fixedly connected. One side of the second limiting plate is provided with a second limiting groove. An adjusting component is arranged inside the workbench. By designing the adjusting component, the wear-resistant lining plate body to be edge ground is placed on the first limiting plate, and by manually rotating the handle, the two T-shaped clamping plates move relatively to fix the wear-resistant lining plate body.

[0004] Although the above-mentioned prior art can fix the wear-resistant lining plate during edge grinding, on the one hand, due to the large volume of the clamping mechanism, it affects the reasonable arrangement of the grinding mechanism and the flexible movement during the grinding process. On the other hand, due to the intense friction generated during the contact between the grinding wheel and the lining plate, these frictions will generate high-frequency fine vibrations. As the processing time increases, it is easy to cause the processing position of the lining plate to shift, thus affecting the accuracy of the edge grinding of the lining plate. Therefore, it does not meet the existing requirements. For this reason, we propose a wear-resistant lining plate edge grinding device and an edge grinding method thereof. Summary of the Invention

[0005] The purpose of the present invention is to provide a wear-resistant lining plate edge grinding device and an edge grinding method thereof to solve the problems proposed in the above background art that the large volume of the lining plate edge grinding device affects the reasonable arrangement and flexible movement of the grinding mechanism, and the intense friction generated during the contact between the grinding wheel and the lining plate is likely to cause the processing position of the lining plate to shift.

[0006] To achieve the above object, the present invention provides the following technical solution: a wear-resistant lining edge grinding device, including a base.

[0008] Preferably, a back plate is welded and fixed to the rear end of the upper end face of the base. At the front side of the top end of the back plate, a top plate is integrally formed. A hydraulic lifting device is installed at the front end of the top plate, and the fixed end of the hydraulic lifting device is fixed to the top plate through bolts. The movable end of the hydraulic lifting device is installed with a clamping wheel. The clamping wheel is connected to the hydraulic lifting device through a bearing, and the center of the clamping wheel and the center of the placement plate are on the same vertical line.

[0009] Preferably, a positioning mechanism is installed in the inner cavity of the base, and the positioning mechanism is slidably matched with the inner cavity of the base. At the upper end inside the positioning mechanism, a chuck is rotatably installed. On the upper end face of the chuck, a plurality of symmetrically distributed claws are installed. The side wall of the claw is limited and slidable with the slot on the upper end face of the positioning mechanism, and the limiting thread on the lower end face of the claw meshes with the flat thread on the contact end face of the chuck. On the upper end face of the claw, a positioning plate is fixed through bolts. At the upper end of the inner cavity of the base, a plurality of symmetrically distributed guide grooves are provided, and the positioning plate is limited and slidable with the guide grooves. At the lower end inside the positioning mechanism, a second motor is fixedly installed, and the output shaft of the second motor is connected to the shaft at the bottom of the chuck through a coupling.

[0010] Preferably, a lifting seat is fixedly arranged at the bottom of the positioning mechanism, and the lifting seat is slidably limited in the inner cavity of the base. A third motor is fixedly installed at the bottom of the base, and a lifting screw rod is installed on the output shaft of the third motor. The lifting screw rod extends into the interior of the lifting seat and is threadedly connected to the lifting seat.

[0011] Preferably, pressure sensors are installed at the upper ends of the inner sides of the positioning plates, and the pressure sensors are fixed to the positioning plates by screws. The output ends of the pressure sensors are connected to a single-chip microcomputer, and the output ends of the single-chip microcomputer are respectively connected to the second motor and the third motor.

[0012] Preferably, an adjusting seat is installed on one side of the upper end surface of the base, and the adjusting seat is slidably matched with the base. An electric push rod is fixedly installed on the outer side of the adjusting seat, a driving device is installed at the movable end of the electric push rod, and a grinding wheel is installed on one side of the bottom of the driving device.

[0013] Preferably, a first motor is fixedly installed on one side of the rear end of the base, a horizontal displacement screw rod is rotatably installed at the upper end of one side inside the base, and the output shaft of the first motor is fixed to one end of the horizontal displacement screw rod. A sliding block in threaded fit is installed on the outer part of the horizontal displacement screw rod, and the upper end of the sliding block is fixed to the bottom of the adjusting seat.

[0014] Preferably, a fourth motor is fixedly installed at the position where the base is located at the lower end of the support base, and the output shaft of the fourth motor is fixed to the shaft at the bottom of the support base through a coupling.

[0015] The edge grinding method of the wear-resistant lining edge grinding device includes the following steps: Step 1: Place the wear-resistant lining on the placing plate, and the positioning plates on the positioning mechanism should extend to the upper end of the base to prepare for subsequent positioning operations; Step 2: Start the second motor, and its output shaft drives the chuck to rotate. Since the limiting threads on the lower end surfaces of the jaws are engaged with the flat threads on the contact end surfaces of the chuck, the jaws equipped with the positioning plates move along the direction of the guide groove under the rotation of the flat threads. The positioning plates move synchronously towards the lining direction under the limitation of the guide groove until their inner sides are in contact with the edges of the lining. At this time, the positioning plates generate a thrust on the lining, keeping the lining centered above the placing plate. After alignment, as the pressure increases, the pressure sensors can timely detect the change of the pressure value. When the pressure reaches the preset value, turn off the second motor and stop the continuous movement of the positioning plates; Step 3: Turn on the hydraulic lifting device to drive the clamping wheel at the movable end to descend, apply pressure to the center position of the upper end face of the lining plate, and fix the lining plate at the upper end with the clamping wheel. At the same time, after the placing plate is stressed, it will move downward, causing the fixing ring and the sleeve on the plate body reinforcement mechanism to approach continuously. During the downward movement of the fixing ring, the piston will be driven to move downward through the piston rod, and the air at the bottom of the piston will be discharged to the outside through the first through hole and the second through hole. A negative pressure is generated in the space above the piston where the sleeve is located, and the lining plate is firmly adsorbed through the rubber ring; Step 4: After the lining plate is clamped and fixed, turn on the motor inside the driving device to drive the grinding wheel below to rotate at high speed. Through the action of the electric push rod, the grinding wheel is brought close to the edge of the lining plate. After the two come into contact, the edge of the lining plate is ground under the action of friction. Turn on the first motor to drive the adjusting seat above to move back and forth, so that the grinding wheel moves along the edge of the lining plate. In cooperation with the electric push rod, grind along the side of the lining plate. If it is necessary to adapt to lining plates of different shapes for edge grinding, turn on the fourth motor to drive the support base above and the lining plate to adjust the angle; Step 5: After grinding is completed, the hydraulic lifting device drives the clamping wheel to rise, and the pressure on the lining plate is lost. At this time, under the action of the return spring, an upward force is generated on the placing plate through the guide post, driving the piston to move upward in the sleeve. The negative pressure value at the upper end inside the sleeve decreases, so that the rubber ring is automatically separated from the lining plate. Finally, the staff takes out the ground lining plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is provided with a plate body reinforcement mechanism and a relatively compact clamping mechanism is designed. Compared with the traditional large clamping mechanism, the space occupied by the grinding mechanism is greatly reduced, enabling the grinding mechanism to move and adjust more flexibly, improving the efficiency and operability of the entire edge grinding process. Through the combination of the plate body reinforcement mechanism and the hydraulic lifting device, the lining plate is not only fixed from the upper end by the clamping wheel, but also a negative pressure adsorption effect is generated by the plate body reinforcement mechanism below. The dual fixing mechanism greatly enhances the stability of the lining plate during the grinding process. This design effectively avoids the problem of the lining plate position deviation caused by the high-frequency and subtle vibrations generated by the grinding friction, thereby ensuring the accuracy of the lining plate edge grinding and improving the product quality of the wear-resistant lining plate. The design of the corrugated sealing rubber sleeve not only ensures the connection tightness between the fixing ring and the sleeve, but also provides the necessary telescopic space, enabling the device to adapt to the processing requirements of lining plates of different thicknesses and sizes, enhancing the versatility and flexibility of the device. After grinding is completed, the automatic upward movement of the hydraulic lifting device in cooperation with the action of the return spring and the guide post enables the rubber ring to be automatically separated from the lining plate without manual disassembly, greatly simplifying the operation process and improving the work efficiency. At the same time, this automatic design also reduces the influence of human factors on the grinding quality, making the entire edge grinding process more standardized and controllable.

[0017] 2. The present invention is provided with a positioning mechanism. Before the edge grinding equipment is started, the positioning mechanism can automatically and accurately position the lining plate at the center position of the placement plate. Driven by the second motor, the chuck rotates and drives the jaws equipped with the positioning plate to move along the guide groove until the inner side of the positioning plate is in close contact with the edge of the lining plate, thereby ensuring that the lining plate is centered and aligned in the horizontal direction. This function greatly improves the accuracy and consistency of the edge grinding process, reducing problems such as uneven grinding or excessive grinding caused by the position deviation of the lining plate. During the positioning process, the application of the pressure sensor realizes the real-time monitoring of the pressure applied to the positioning plate. When the positioning plate contacts the lining plate and generates sufficient thrust to align the lining plate, the pressure sensor can quickly respond and turn off the second motor, stopping the continued movement of the positioning plate, thereby avoiding damage to the lining plate or the positioning mechanism caused by excessive thrust. This intelligent control not only improves the processing efficiency but also enhances the safety and reliability of the equipment. The design of the positioning mechanism allows it to automatically retract into the base after completing the positioning task, ensuring that the upper end surface of the base is unobstructed, providing good preconditions for the operation of the edge grinding mechanism.

[0018] 3. The present invention is provided with a flexible edge grinding mechanism. The flexible edge grinding mechanism drives the grinding wheel to rotate at high speed through a motor and is in close contact with the edge of the lining plate under the action of the electric push rod to achieve efficient edge grinding. This design can ensure full contact between the grinding wheel and the edge of the lining plate, thereby quickly forming a smooth edge under the action of intense friction. At the same time, by adjusting the stroke of the electric push rod, the grinding depth can be accurately controlled to meet different processing requirements. The introduction of the first motor enables the adjustment seat to move back and forth along the horizontal displacement screw, thereby realizing the position movement of the grinding wheel at the edge of the lining plate. This design not only improves the flexibility of the edge grinding process but also can adapt to lining plates of different lengths and shapes to achieve comprehensive edge grinding. In addition, the rotational connection between the support base and the base and the drive of the fourth motor enable the upper lining plate to be angle-adjusted, further enhancing the adaptability and flexibility of the equipment, ensuring the smoothness and consistency of the edge of the lining plate, and improving the processing quality of the product.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Please refer to Figure 1-7 , an embodiment provided by the present invention: a wear-resistant lining edge grinding device, including a base 1, a support base 2 is installed at the center position of the upper end surface of the base 1, and the support base 2 is connected to the base 1 through a bearing. A placement plate 3 with the same radius as it is arranged above the support base 2, and a fixed gap is maintained between the support base 2 and the placement plate 3. An annularly distributed plate reinforcement mechanism 4 is provided between the placement plate 3 and the support base 2. The plate reinforcement mechanism 4 includes a sleeve 26, which is embedded in the support base 2. A corrugated sealing rubber sleeve 27 is arranged above the sleeve 26, and the corrugated sealing rubber sleeve 27 is located at the gap position between the support base 2 and the placement plate 3. A fixing ring 28 is arranged above the corrugated sealing rubber sleeve 27, and the fixing ring 28 is embedded in the placement plate 3. The two ends of the corrugated sealing rubber sleeve 27 are respectively sealed and connected to the sleeve 26 and the fixing ring 28. A rubber ring 29 is arranged at the top end of the fixing ring 28, and the rubber ring 29 is located on the upper end surface of the placement plate 3. A piston 30 is installed inside the sleeve 26, a piston rod 31 is fixedly arranged at the top end of the piston 30, and a fixing piece 32 is fixedly arranged inside the fixing ring 28. The fixing piece 32 is in a cross structure, and the bottom of the fixing piece 32 is fixed to the upper end of the piston rod 31; After the placement plate 3 is subjected to pressure, it will move downward, causing the fixed ring 28 and the sleeve 26 on the plate reinforcement mechanism 4 to approach each other continuously. At the same time, the corrugated seal sleeve 27 between them provides a telescopic space on the premise of ensuring the connection tightness between the fixed ring 28 and the sleeve 26. During the downward movement of the fixed ring 28, the piston 30 will be driven to move downward through the piston rod 31. The air at the bottom of the piston 30 is discharged to the outside through the first through hole 33 and the second through hole 34. At the same time, a huge negative pressure is generated in the space above the piston 30 where the sleeve 26 is located. The negative pressure sends air through the rubber ring 29 above the fixed ring 28, and the upper end surface of the rubber ring 29 is in contact with the lining plate. At the same time, under the action of the clamping wheel 10, the bottom surface of the lining plate is closely attached to the rubber ring 29 to form a seal, and air cannot be supplemented from above the rubber ring 29. Therefore, under the intense negative pressure, the rubber ring 29 firmly adsorbs the lining plate.

[0023] Please refer to Figure 4 and Figure 5 , a guide hole 35 is provided at the middle position inside the support base 2, and a guide post 37 is fixedly provided at the middle position of the bottom of the placement plate 3. The guide post 37 extends into the inside of the guide hole 35, and the guide post 37 is slidably limited with the guide hole 35. A return spring 36 is fixedly installed between the inner hole of the guide post 37 and the guide hole 35. After the grinding is completed, the hydraulic lifting device 9 drives the clamping wheel 10 to rise, losing the pressure on the lining plate. At this time, under the action of the return spring 36, an upward force is generated on the placement plate 3 through the guide post 37, driving the piston 30 to move upward in the sleeve 26, reducing the negative pressure value at the upper end inside the sleeve 26, thereby automatically separating the rubber ring 29 from the lining plate, facilitating the staff to take out the ground lining plate.

[0024] Please refer to Figure 1 , the back plate 7 is fixedly welded to the rear end of the upper end surface of the base 1. The front side of the top end of the back plate 7 is integrally formed with the top plate 8. The hydraulic lifting device 9 is installed at the front end of the top plate 8, and the fixed end of the hydraulic lifting device 9 is fixed to the top plate 8 by bolts. The movable end of the hydraulic lifting device 9 is installed with the clamping wheel 10. The clamping wheel 10 is connected to the hydraulic lifting device 9 through a bearing, and the center of the clamping wheel 10 and the center of the placement plate 3 are on the same vertical line. By designing a relatively compact clamping mechanism, compared with the traditional large clamping mechanism, the occupied space for the grinding mechanism layout is greatly reduced, enabling the grinding mechanism to move and adjust more flexibly, improving the efficiency and operability of the entire edge grinding process. By combining the plate reinforcement mechanism and the hydraulic lifting device, not only the lining plate is fixed from above through the clamping wheel, but also a negative pressure adsorption effect is generated by the plate reinforcement mechanism below, and the double fixation mechanism greatly enhances the stability of the lining plate during the grinding process.

[0025] Please refer to Figure 1 , Figure 3 , Figure 4 andFigure 7 , a positioning mechanism 16 is installed in the inner cavity of the base 1, and the positioning mechanism 16 is slidably matched with the inner cavity of the base 1. A chuck 17 is rotatably installed at the upper end inside the positioning mechanism 16. A plurality of symmetrically distributed claws 18 are installed on the upper end surface of the chuck 17. The side wall of the claw 18 is limited and slid in the slot on the upper end surface of the positioning mechanism 16, and the limiting thread on the lower end surface of the claw 18 meshes with the planar thread on the contact end surface of the chuck 17. A positioning plate 6 is fixedly installed on the upper end surface of the claw 18 through bolts. A plurality of symmetrically distributed guide grooves 5 are provided at the upper end of the inner cavity of the base 1, and the positioning plate 6 is limited and slid in the guide grooves 5. A second motor 20 is fixedly installed at the lower end inside the positioning mechanism 16, and the output shaft of the second motor 20 is connected to the shaft at the bottom of the chuck 17 through a coupling; The output shaft of the second motor 20 drives the chuck 17 to rotate. Since the limiting thread on the lower end surface of the claw 18 meshes with the planar thread on the contact end surface of the chuck 17, the planar thread rotates to drive the claw 18 equipped with the positioning plate 6 to move along the direction of the guide groove 5. Then the positioning plate 6 moves synchronously towards the liner direction under the limitation of the guide groove 5 until its inner side abuts against the edge of the liner. After contact, a thrust is generated on the liner, so that the liner is kept centered above the placement plate 3.

[0026] Please refer to Figure 4 , a lifting seat 21 is fixedly arranged at the bottom of the positioning mechanism 16, and the lifting seat 21 is slidably limited in the inner cavity of the base 1. A third motor 22 is fixedly installed at the bottom of the base 1. A lifting screw 23 is installed on the output shaft of the third motor 22. The lifting screw 23 extends into the inside of the lifting seat 21, and the lifting screw 23 is threadedly connected to the lifting seat 21. Pressure sensors 19 are installed at the upper ends inside the positioning plate 6, and the pressure sensors 19 are fixedly connected to the positioning plate 6 through screws. The output end of the pressure sensor 19 is connected to a single-chip microcomputer, and the output end of the single-chip microcomputer is respectively connected to the second motor 20 and the third motor 22. After alignment, as the pressure increases, the pressure sensor 19 can timely detect the change of the pressure value, so as to turn off the second motor 20 and stop the continuous movement of the positioning plate 6. Subsequently, the third motor 22 is turned on, and its output shaft drives the lifting screw 23 to rotate. Under the friction between its external thread and the internal thread hole in the lifting seat 21 at the bottom of the positioning mechanism 16, and in cooperation with the guiding effect of the inner cavity of the base 1 on the lifting column (although the lifting column is not directly mentioned in this description, it can be understood that the cooperation between the lifting seat and the base plays a guiding role), the positioning mechanism 16 drives the positioning plate 6 to move downward until the positioning plate 6 retracts into the guide groove 5 to ensure that the upper end surface of the base 1 is unobstructed.

[0027] Please refer to Figure 1 , Figure 3 and Figure 4, on one side of the upper end face of the base 1, an adjustment seat 11 is installed, and the adjustment seat 11 is slidably matched with the base 1. An electric push rod 12 is fixedly installed on the outer side of the adjustment seat 11. A driving device 13 is installed at the movable end of the electric push rod 12. A grinding wheel 14 is installed on one side of the bottom of the driving device 13. A first motor 15 is fixedly installed on one side of the rear end of the base 1. A horizontal displacement screw 24 is rotatably installed at the upper end of one side inside the base 1, and the output shaft of the first motor 15 is fixed to one end of the horizontal displacement screw 24. A sliding block 25 in threaded fit is installed on the outside of the horizontal displacement screw 24, and the upper end of the sliding block 25 is fixed to the bottom of the adjustment seat 11. The base 1 is fixedly installed with a fourth motor 38 at the lower end position of the support base 2, and the output shaft of the fourth motor 38 is fixed to the shaft at the bottom of the support base 2 through a coupling.

[0028] The edge grinding method of the wear-resistant lining edge grinding device includes the following steps: Step 1: Place the wear-resistant lining on the placing plate 3, and the positioning plate 6 on the positioning mechanism 16 should extend to the upper end of the base 1 to prepare for subsequent positioning operations; Step 2: Start the second motor 20, and its output shaft drives the chuck 17 to rotate. Since the limiting thread on the lower end face of the chuck 18 meshes with the flat thread on the contact end face of the chuck 17, the flat thread rotation drives the chuck 18 equipped with the positioning plate 6 to move along the direction of the guide groove 5. The positioning plate 6 moves synchronously towards the lining direction under the limitation of the guide groove 5 until its inner side abuts against the edge of the lining. At this time, the positioning plate 6 generates a thrust on the lining, so that the lining is centered above the placing plate 3. After alignment, as the pressure increases, the pressure sensor 19 can detect the change of the pressure value in time. When the pressure reaches the preset value, turn off the second motor 20 and stop the continuous movement of the positioning plate 6; Step 3: Turn on the hydraulic lifting device 9 to drive the clamping wheel 10 at the movable end to descend and press on the center position of the upper end face of the lining. The clamping wheel 10 fixes the lining at the upper end. At the same time, after the placing plate 3 is subjected to pressure, it will move downward, causing the fixing ring 28 and the sleeve 26 on the plate body strengthening mechanism 4 to approach each other continuously. During the downward movement of the fixing ring 28, the piston 30 will be driven to move downward through the piston rod 31. The air at the bottom of the piston 30 is discharged to the outside through the first through hole 33 and the second through hole 34. A negative pressure is generated in the space above the piston 30 where the sleeve 26 is located, and the lining is firmly adsorbed through the rubber ring 29; Step 4: After the liner is clamped and fixed, start the motor inside the driving device 13 to drive the grinding wheel 14 below to rotate at a high speed. Through the action of the electric push rod 12, make the grinding wheel 14 approach the edge of the liner. After the two come into contact, the grinding of the liner edge is formed under the friction. Start the first motor 15 to drive the adjusting seat 11 above to move back and forth, so that the grinding wheel 14 moves along the edge of the liner. Cooperate with the electric push rod 12 to grind along the side of the liner. If it is necessary to adapt to liners of different shapes for edge grinding, start the fourth motor 38 to drive the support base 2 above and the liner to adjust the angle; Step 5: After the grinding is completed, the hydraulic lifting device 9 drives the clamping wheel 10 to rise, losing the pressure on the liner. At this time, under the action of the return spring 36, a upward force is generated on the placing plate 3 through the guide post 37, driving the piston 30 to move upward in the sleeve 26. The negative pressure value at the upper end inside the sleeve 26 decreases, so as to automatically separate the rubber ring 29 from the liner. Finally, the staff takes out the ground liner.

10. The edge grinding method based on the wear-resistant lining plate edge grinding device according to claim 9, characterized in that: The steps include: Step 1: Place the wear-resistant lining on the placement plate (3), and the positioning plate (6) on the positioning mechanism (16) should extend to the upper end of the base (1) to prepare for the subsequent positioning operation; Step 2, start the second motor (20), and its output shaft drives the chuck (17) to rotate. Since the limiting thread on the lower end face of the claw (18) is meshed with the flat thread on the contact end face of the chuck (17), the flat thread rotates and drives the claw (18) equipped with the positioning plate (6) to move along the direction of the guide groove (5). The positioning plate (6) is synchronously moved in the direction of the lining plate under the limiting position of the guide groove (5) until its inner side is in contact with the edge of the lining plate. At this time, the positioning plate (6) generates a thrust on the lining plate, so that the lining plate is kept aligned with the center above the placement plate (3). After alignment, as the pressure increases, the pressure sensor (19) can detect the change of the pressure value in time. When the pressure reaches the preset value, the second motor (20) is turned off to stop the positioning plate (6) from moving further. Step 3: Turn on the hydraulic lifting device (9) to drive the clamping wheel (10) at the movable end to descend, and apply pressure to the lining plate at the center of its upper end surface. The clamping wheel (10) fixes the lining plate at the upper end. At the same time, the placement plate (3) moves downward after being subjected to pressure, so that the fixing ring (28) and the sleeve (26) on the plate reinforcement mechanism (4) are constantly approaching each other. During the downward movement of the fixing ring (28), the piston (30) is driven downward through the piston rod (31). The air at the bottom of the piston (30) is discharged to the outside through the first through hole (33) and the second through hole (34). Negative pressure is generated in the space above the piston (30) where the sleeve (26) is located, and the lining plate is firmly adsorbed through the rubber ring (29); Step 4: After the lining plate is clamped and fixed, the motor inside the driving device (13) is turned on to drive the grinding wheel (14) below to rotate at a high speed. Through the action of the electric push rod (12), the grinding wheel (14) and the edge of the lining plate are brought close to each other. After the two are in contact, the edge of the lining plate is polished under the action of friction. The first motor (15) is turned on to drive the upper adjustment seat (11) to move forward and backward, so that the grinding wheel (14) moves to the position of the edge of the lining plate. In cooperation with the electric push rod (12), the side of the lining plate is polished. If it is necessary to adapt to the lining plate of different shapes for edge grinding, the fourth motor (38) is turned on to drive the upper support base (2) and the lining plate to adjust the angle; Step 5. After the grinding is completed, the hydraulic lifting device (9) drives the clamping wheel (10) to rise, and the pressure on the lining plate is lost. At this time, under the action of the return spring (36), the guide column (37) generates an upward force on the placement plate (3), driving the piston (30) to move upward in the sleeve (26). The negative pressure value at the upper end of the sleeve (26) decreases, thereby automatically separating the rubber ring (29) from the lining plate. Finally, the staff takes out the polished lining plate.
