A diesel engine flywheel bore wall grinding device and its usage method

Abstract

This invention relates to the field of hole wall grinding technology, and discloses a diesel engine flywheel hole wall grinding device and its usage method. The device includes an air guide assembly, which includes a mounting plate. A fixing rod is fixedly connected to the bottom of the mounting plate, and a fixing plate is fixedly connected to the bottom of the fixing rod. When grinding the flywheel hole wall, the device is controlled to move linearly towards the flywheel and push the bottom ring. As the bottom ring moves, it drives a pressure plate to move via a connecting rod. During this movement, the pressure plate pushes air from the fixed housing into the air guide chamber. The air entering the air guide chamber pushes several sliding plates away from each other. After the grinding block moves a certain distance, its outer wall contacts the hole wall. As air continues to enter the air guide chamber, the pressure in the air guide chamber increases, thus providing a certain force to the sliding plates. This force is evenly distributed on the sliding plates, ensuring uniform contact force between the grinding block and the hole wall.

Description

Technical Field

[0001] This invention relates to the field of hole wall grinding technology, specifically to a diesel engine flywheel hole wall grinding device and its usage method. Background Technology

[0002] In the manufacturing and maintenance of diesel engines, the flywheel is a critical component, and the quality of its bore walls directly affects the engine's performance and reliability. Flywheel bore walls may develop defects such as unevenness and burrs due to insufficient machining precision, wear, or other factors. These defects not only affect the flywheel's balance but may also lead to vibration and noise during high-speed operation. Therefore, effective grinding of the flywheel bore walls is essential.

[0003] When using a hole wall grinding device, the grinding head is usually adjustable to accommodate different hole diameters. However, the grinding head is mostly adjusted by a spring. Although this design can adapt to different hole diameters within a certain range, it has obvious shortcomings. Specifically, the force applied by the spring is often not uniform, resulting in uneven pressure distribution when the grinding head contacts the hole wall. This uneven force will lead to differences in grinding effect, causing some areas to be over-ground while other areas may be under-ground, ultimately affecting the flatness and smoothness of the hole wall. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a diesel engine flywheel hole wall grinding device, including an air guide assembly, the air guide assembly including a mounting plate, a fixing rod fixedly connected to the bottom of the mounting plate, and a fixing plate fixedly connected to the bottom of the fixing rod;

[0005] The rotating assembly includes a motor fixedly connected to the top of the mounting plate, a rotating shaft fixedly connected to the output end of the motor, and a rotating column fixedly connected to the bottom of the rotating shaft;

[0006] The adjustment assembly includes a mounting bracket located below the mounting plate, a sealing plate slidably connected to the inner wall of the mounting bracket, and a spring fixedly connected to the bottom of the sealing plate.

[0007] Preferably, a fixed shell is fixedly connected to the top of the fixed plate, and the top of the fixed shell is fixedly connected to the bottom of the mounting plate. A pressure plate is slidably connected to the inner wall of the fixed shell, and a connecting rod is fixedly connected to the bottom of the pressure plate. The outer surface of the connecting rod is slidably connected to the inner wall of the fixed plate, and a bottom ring is fixedly connected to the bottom of the connecting rod. A spring is fixedly connected to the top of the pressure plate, and the top of the spring is fixedly connected to the bottom of the mounting plate. Two air guide hoses are fixedly connected to the outer wall of the fixed shell. When using this device, first install the device on a robotic arm or other control device. When grinding the flywheel hole wall, position the device directly in front of the hole to be ground on the flywheel. Then control the device to move linearly towards the flywheel, so that the entire shell enters the hole. As the device continues to move, the outer wall of the bottom ring will contact the outer wall of the flywheel and push the bottom ring. When the bottom ring moves, it will drive the pressure plate to move through the connecting rod. During the movement, the pressure plate will compress the spring and push the air in the fixed shell into the air guide hose.

[0008] Preferably, a sealing ring is fixedly connected to the end of the air guide hose away from the fixed housing. A fixed post is fixedly connected to the top of the sealing ring. A rotating housing is slidably connected to the outer surface of the sealing ring. An air guide chamber is formed inside the rotating housing. A sliding plate is slidably connected to the inner wall of the rotating housing. A grinding block is fixedly connected to the inner wall of the sliding plate. Bending plates are fixedly connected to the top and bottom of the sliding plate. A ring spring contacts the inner wall of the bending plate. The air guide hose will introduce air into the sealing ring. The air introduced into the sealing ring will enter the air guide chamber. The air entering the air guide chamber will push several sliding plates in a direction away from each other. As the moving plate moves, it drives the grinding block and the bending plate to move together. During the movement, the bending plate stretches the ring spring. After the grinding block moves a certain distance, its outer wall will contact the hole wall. As air is continuously input into the air guide chamber, the pressure in the air guide chamber will increase, which will then provide a certain force to the sliding plate. This force will be evenly applied to the sliding plate. This design can provide a uniform force to the sliding plate through air, ensuring that the contact force between the grinding block and the hole wall is evenly distributed. This helps to avoid uneven wear or hole wall damage caused by excessive local force.

[0009] Preferably, a second air guide hose is fixedly connected to the right side of the fixed shell, a second air guide chamber is opened inside the bottom ring, and a nozzle is fixedly connected to the top of the bottom ring. During the movement of the pressure plate, it will also draw air from the second air guide hose into the interior of the fixed shell. The second air guide hose will draw air out of the second air guide chamber. The second air guide chamber will draw in external air through the nozzle to compensate for the air entering the fixed shell. During the subsequent grinding process, when the device moves away from the flywheel, the pressure plate will be reset under the action of the first spring. During the reset process, it will push the air drawn into the fixed shell back into the second air guide hose. The second air guide hose will then pass air into the second air guide chamber. The air entering the second air guide chamber will be ejected again from the nozzle. The ejected air will flow at a certain angle and finally hit the surface of the grinding block and other structures. This design can clean the dust attached to the surface of the grinding block and other structures through the air ejected from the nozzle, keeping the device clean and allowing the grinding block to contact the hole wall more evenly during the subsequent grinding process.

[0010] Preferably, the outer surface of the rotating shaft is rotatably connected to the inner wall of the mounting plate, a sliding ring is slidably connected to the outer surface of the rotating column, the inner wall of the sliding ring is slidably connected to the outer surface of the fixed rod, a second connecting rod is fixedly connected to the bottom of the sliding ring, a lifting plate is fixedly connected to the bottom of the second connecting rod, and a rotating rod is fixedly connected to the bottom of the rotating column. After the grinding block contacts the hole wall and applies appropriate force, the motor can be started to grind the hole wall. In the above process, after the motor starts, it will drive the rotating column to rotate through the rotating shaft. During the rotation of the rotating column, the sliding ring will move through the groove opened on its outer surface. Under the limiting action of the fixed rod, the sliding ring will move up and down along the groove opened on the rotating column. During the rotation of the rotating column, the rotating shell will be driven to rotate through the rotating rod, and then the hole wall will be ground by the grinding block.

[0011] Preferably, the outer surface of the rotating rod is rotatably connected to the inner wall of the lifting plate, and the outer surface of the rotating rod is slidably connected to the inner wall of the rotating shell. A connecting sleeve is fixedly connected to the bottom of the lifting plate, and the outer surface of the connecting sleeve is rotatably connected to the inner wall of the rotating shell. The top of the fixed column is fixedly connected to the bottom of the lifting plate. During the up-and-down reciprocating movement of the sliding ring, it will drive the lifting plate to move up and down reciprocatingly through the connecting rod. The lifting plate will drive the rotating shell to move up and down reciprocatingly through the connecting sleeve. Thus, when the grinding block is rotating and grinding the hole wall, it can also move up and down reciprocatingly. This design can make the contact point of the grinding block on the hole wall constantly change through the action of the grinding block rotating and moving up and down, ensuring that the entire hole wall can be fully ground, improving the uniformity of grinding, making the hole wall surface smoother and flatter, and also making the wear of the grinding block itself evenly distributed.

[0012] Preferably, the top of the fixed frame is fixedly connected to the bottom of the rotating shell, the outer surface of the sealing plate is slidably connected to the inner wall of the rotating shell, and an adjusting plate is fixedly connected to the bottom of the second spring. The outer surface of the adjusting plate is slidably connected to the inner wall of the fixed frame, and a threaded rod is rotatably connected to the inner wall of the adjusting plate. The outer surface of the threaded rod is threadedly connected to the inner wall of the fixed frame. During the process of air entering the first air guide chamber, the pressure inside the first air guide chamber will continue to increase as air is continuously input. When the pressure increases to a certain level, the sealing plate will overcome the elastic force of the second spring and move downward. When the sealing plate moves to the point of separating from the inner wall of the rotating shell, the air in the first air guide chamber can then pass through the outer surface of the sealing plate. The gap between the surface and the rotating shell enters the fixed frame and can enter the outside through the through hole in the outer wall of the fixed frame. This allows the pressure in the first air guide chamber to be maintained within a certain range. By rotating the threaded rod, the adjusting plate can be moved upward to compress the second spring. This requires the sealing plate to exert greater force to overcome the elasticity of the second spring and separate from the rotating shell, thereby adjusting the pressure range in the first air guide chamber. This design can maintain the pressure in the first air guide chamber within a certain range, preventing excessive pressure from causing the grinding block to apply too much force to the hole wall, resulting in excessive cutting of the hole wall material by the grinding block in a short period of time, causing over-grinding.

[0013] A method for using a diesel engine flywheel bore wall grinding device includes the following steps:

[0014] S1: When using this device, first install it on a robotic arm or other control device, then control the device to move in a straight line and approach the flywheel. The outer wall of the bottom ring will contact the outer wall of the flywheel and push the bottom ring. In turn, the sliding plate can be given a certain force by pushing the air.

[0015] S2: During the process of air being introduced into the first air guide chamber, when the pressure increases to a certain level, the air can enter the outside through the gap between the outer surface of the sealing plate and the rotating shell, thereby maintaining the pressure in the first air guide chamber within a certain range.

[0016] S3: After the grinding block contacts the hole wall and applies appropriate force, the motor can be started to grind the hole wall while rotating and moving up and down. During the reset of the pressure plate, air will be ejected from the nozzle and finally hit the surface of the grinding block and other structures.

[0017] The present invention has the following beneficial effects:

[0018] 1. When grinding the flywheel hole wall, this invention positions the device directly over the hole to be ground on the flywheel. The device is then controlled to move linearly towards the flywheel, causing the entire rotating housing to enter the hole. As the device continues to move, the outer wall of the bottom ring contacts the outer wall of the flywheel, pushing the bottom ring. During this movement, the bottom ring moves via a connecting rod, causing a pressure plate to move. The pressure plate compresses a spring and pushes air from the fixed housing into a duct hose. The duct hose then introduces air into a sealing ring, which in turn enters a duct chamber. The air in the duct chamber pushes several sliding plates towards... As the sliding plate moves in opposite directions, it pulls the grinding block and the bending plate together. During the movement, the bending plate stretches the ring spring. After the grinding block moves a certain distance, its outer wall contacts the hole wall. As air continues to enter the air guide chamber, the pressure in the air guide chamber increases, which in turn provides a certain force to the sliding plate. This force is evenly applied to the sliding plate. This design ensures that the contact force between the grinding block and the hole wall is evenly distributed by the air, which helps to avoid uneven wear or hole wall damage caused by excessive local force.

[0019] 2. During the movement of the pressure plate, the invention also draws air from the second air guide hose into the interior of the fixed shell. The second air guide hose then draws air out of the second air guide chamber, which in turn draws in external air through the nozzle to compensate for the air entering the fixed shell. As the device moves away from the flywheel after subsequent grinding, the pressure plate resets under the action of the first spring. During the reset process, the pressure plate pushes the air drawn into the fixed shell back into the second air guide hose, which then introduces air into the second air guide chamber. The air entering the second air guide chamber is then ejected from the nozzle again. The ejected air flows at a certain angle and eventually hits the surface of the grinding block and other structures. This design can clean the dust adhering to the surface of the grinding block and other structures through the air ejected from the nozzle, keeping the device clean and allowing the grinding block to contact the hole wall more evenly during subsequent grinding.

[0020] 3. In this invention, after the grinding block contacts the hole wall and a suitable force is applied, the motor can be started to grind the hole wall. During the above process, after the motor starts, it will drive the rotating column to rotate via the rotating shaft. During the rotation of the rotating column, it will drive the sliding ring to move through the sliding groove on its outer surface. Under the limiting action of the fixed rod, the sliding ring will move up and down along the sliding groove on the rotating column. During the rotation of the rotating column, it will drive the entire rotating shell to rotate via the rotating rod, thereby grinding the hole wall through the grinding block, while the sliding ring moves up and down. During the movement, it will drive the lifting plate to move up and down reciprocally through the connecting rod two. The lifting plate will drive the rotating shell to move up and down reciprocally through the connecting sleeve. This allows the grinding block to move up and down reciprocally while rotating and grinding the hole wall. This design allows the contact point of the grinding block on the hole wall to change continuously through the action of the grinding block rotating and moving up and down, ensuring that the entire hole wall can be fully ground, improving the uniformity of grinding, making the hole wall surface smoother and flatter, and at the same time, making the wear on the grinding block itself evenly distributed.

[0021] 4. During the process of air entering the first air guide cavity, the pressure inside the first air guide cavity will continuously increase as air is continuously input. When the pressure increases to a certain level, the sealing plate will overcome the elastic force of the second spring and move downward. When the sealing plate moves to the point of separating from the inner wall of the rotating shell, the air in the first air guide cavity can enter the fixed frame through the gap between the outer surface of the sealing plate and the rotating shell, and can enter the outside through the through hole opened on the outer wall of the fixed frame. Thus, the pressure in the first air guide cavity can be maintained within a certain range. By rotating the threaded rod, the adjusting plate can be moved upward to compress the second spring, so that the sealing plate needs greater force to overcome the elastic force of the second spring and separate from the rotating shell. Thus, the pressure range in the first air guide cavity can be adjusted. This design can maintain the pressure in the first air guide cavity within a certain range, preventing excessive pressure from causing the grinding block to apply too much force to the hole wall, resulting in excessive cutting of the hole wall material by the grinding block in a short period of time, causing over-grinding.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figure 1 - Figure 5 The present invention is a diesel engine flywheel hole wall grinding device, including an air guide assembly 1, the air guide assembly 1 including a mounting plate 101, a fixing rod 102 fixedly connected to the bottom of the mounting plate 101, and a fixing plate 103 fixedly connected to the bottom of the fixing rod 102.

[0035] Rotating component 2 includes a motor 201 fixedly connected to the top of the mounting plate 101, a rotating shaft 202 fixedly connected to the output end of the motor 201, and a rotating column 203 fixedly connected to the bottom of the rotating shaft 202.

[0036] Adjustment component 3 includes a fixing frame 301 located below the mounting plate 101. A sealing plate 302 is slidably connected to the inner wall of the fixing frame 301, and a spring 303 is fixedly connected to the bottom of the sealing plate 302.

[0037] A fixed housing 107 is fixedly connected to the top of the fixed plate 103. The top of the fixed housing 107 is fixedly connected to the bottom of the mounting plate 101. A pressure plate 104 is slidably connected to the inner wall of the fixed housing 107. A connecting rod 105 is fixedly connected to the bottom of the pressure plate 104. The outer surface of the connecting rod 105 is slidably connected to the inner wall of the fixed plate 103. A bottom ring 106 is fixedly connected to the bottom of the connecting rod 105. A spring 108 is fixedly connected to the top of the pressure plate 104. The top of the spring 108 is fixedly connected to the bottom of the mounting plate 101. Two air guide hoses 109 are fixedly connected to the outer wall of the fixed housing 107. During installation, first install the device onto a robotic arm or other control device. When grinding the flywheel hole wall, position the device directly in front of the hole to be ground on the flywheel. Then, control the device to move in a straight line towards the flywheel, so that the rotating housing 112 enters the hole as a whole. As the device continues to move, the outer wall of the bottom ring 106 will contact the outer wall of the flywheel and push the bottom ring 106. When the bottom ring 106 moves, it will drive the pressure plate 104 to move through the connecting rod 105. During the movement, the pressure plate 104 will compress the spring 108 and push the air in the fixed housing 107 into the air guide hose 109.

[0038] A sealing ring 110 is fixedly connected to the end of the air guide hose 109 away from the fixed housing 107. A fixed post 111 is fixedly connected to the top of the sealing ring 110. A rotating housing 112 is slidably connected to the outer surface of the sealing ring 110. An air guide cavity 113 is opened inside the rotating housing 112. A sliding plate 114 is slidably connected to the inner wall of the rotating housing 112. A grinding block 115 is fixedly connected to the inner wall of the sliding plate 114. A bending plate 116 is fixedly connected to the top and bottom of the sliding plate 114. A ring spring 117 contacts the inner wall of the bending plate 116. The air guide hose 109 will introduce air into the sealing ring 110. The air introduced into the sealing ring 110 will enter the air guide cavity 113. The air entering the air guide cavity 113 will push the sliding plates 111... 4. Pushing in a direction away from each other, the sliding plate 114 will drive the grinding block 115 and the bending plate 116 to move together during the movement. The bending plate 116 will stretch the ring spring 117 during the movement. After the grinding block 115 moves a certain distance, its outer wall will contact the hole wall. As air is continuously input into the air guide chamber 113, the pressure in the air guide chamber 113 will increase, which can then give the sliding plate 114 a certain force. This force will be evenly applied to the sliding plate 114. This design can give the sliding plate 114 a uniform force through air, ensuring that the contact force between the grinding block 115 and the hole wall is evenly distributed, which helps to avoid uneven wear or hole wall damage caused by excessive local force.

[0039] A second air guide hose 118 is fixedly connected to the right side of the fixed housing 107. An air guide chamber 119 is opened inside the bottom ring 106. A nozzle 120 is fixedly connected to the top of the bottom ring 106. During the movement of the pressure plate 104, it will draw air from the second air guide hose 118 into the fixed housing 107. The second air guide hose 118 will draw air out of the second air guide chamber 119. The second air guide chamber 119 will draw in external air through the nozzle 120 to compensate for the air entering the fixed housing 107. After the grinding is completed and the device moves away from the flywheel, the pressure plate 104 will be reset by the action of the first spring 108. During the reset process, the air sucked into the fixed shell 107 will be pushed back into the air guide hose 118. The air guide hose 118 will then introduce air into the air guide chamber 119. The air entering the air guide chamber 119 will be ejected from the nozzle 120 again. The ejected air will flow at a certain angle and finally hit the surface of the grinding block 115 and other structures. This design can clean the dust attached to the surface of the grinding block 115 and other structures with the air ejected from the nozzle 120, keeping the device clean. At the same time, the grinding block 115 can make more even contact with the hole wall during the subsequent grinding process.

[0040] Example 2, please refer to Figure 6 - Figure 8This invention relates to a diesel engine flywheel hole wall grinding device. Based on Example 1, the outer surface of the rotating shaft 202 is rotatably connected to the inner wall of the mounting plate 101. A sliding ring 204 is slidably connected to the outer surface of the rotating column 203. The inner wall of the sliding ring 204 is slidably connected to the outer surface of the fixed rod 102. A connecting rod 205 is fixedly connected to the bottom of the sliding ring 204. A lifting plate 206 is fixedly connected to the bottom of the connecting rod 205. A rotating rod 2031 is fixedly connected to the bottom of the rotating column 203. After the grinding block 115 contacts the hole wall and a suitable force is applied, the device can be started. The motor 201 polishes the hole wall. In the above process, after the motor 201 is started, it will drive the rotating column 203 to rotate through the rotating shaft 202. During the rotation, the rotating column 203 will drive the sliding ring 204 to move through the sliding groove on its outer surface. Under the limiting action of the fixed rod 102, the sliding ring 204 will move up and down along the sliding groove on the rotating column 203. During the rotation, the rotating column 203 will drive the rotating shell 112 to rotate as a whole through the rotating rod 2031, and then polish the hole wall through the polishing block 115.

[0041] The outer surface of the rotating rod 2031 is rotatably connected to the inner wall of the lifting plate 206, and the outer surface of the rotating rod 2031 is slidably connected to the inner wall of the rotating shell 112. A connecting sleeve 207 is fixedly connected to the bottom of the lifting plate 206, and the outer surface of the connecting sleeve 207 is rotatably connected to the inner wall of the rotating shell 112. The top of the fixed column 111 is fixedly connected to the bottom of the lifting plate 206. During the reciprocating movement of the sliding ring 204, it will drive the lifting plate 206 to reciprocate up and down through the connecting rod 205. The connecting sleeve 207 drives the rotating shell 112 to move up and down reciprocally, which allows the grinding block 115 to move up and down reciprocally while rotating and grinding the hole wall. This design allows the grinding block 115 to continuously change its contact point on the hole wall while rotating and moving up and down, ensuring that the entire hole wall is fully ground, improving the uniformity of grinding, making the hole wall surface smoother and flatter, and also ensuring that the wear on the grinding block 115 itself is evenly distributed.

[0042] The top of the fixed frame 301 is fixedly connected to the bottom of the rotating shell 112. The outer surface of the sealing plate 302 is slidably connected to the inner wall of the rotating shell 112. An adjusting plate 304 is fixedly connected to the bottom of the second spring 303. The outer surface of the adjusting plate 304 is slidably connected to the inner wall of the fixed frame 301. A threaded rod 305 is rotatably connected to the inner wall of the adjusting plate 304. The outer surface of the threaded rod 305 is threadedly connected to the inner wall of the fixed frame 301. During the process of air entering the first air guide chamber 113, the pressure inside the first air guide chamber 113 will continue to increase as air is continuously input. When the pressure increases to a certain level, the sealing plate 302 will overcome the elastic force of the second spring 303 and move downward. When the sealing plate 302 moves to the point of separating from the inner wall of the rotating shell 112, the air in the first air guide chamber 113 can then pass through... The gap between the outer surface of the sealing plate 302 and the rotating shell 112 allows it to enter the fixing frame 301 and enter the outside through the through hole in the outer wall of the fixing frame 301. This allows the pressure in the air guide chamber 113 to be maintained within a certain range. By rotating the threaded rod 305, the adjusting plate 304 can be moved upward to compress the second spring 303. This requires the sealing plate 302 to exert greater force to overcome the elasticity of the second spring 303 and separate from the rotating shell 112. This allows the pressure range in the air guide chamber 113 to be adjusted. This design can maintain the pressure in the air guide chamber 113 within a certain range, preventing excessive pressure from causing the grinding block 115 to apply excessive force to the hole wall, resulting in excessive cutting of the hole wall material by the grinding block 115 in a short period of time, causing over-grinding.

[0043] The method of using this hole wall grinding device includes the following steps:

[0044] S1: When using this device, first install this device on a robotic arm or other control device, then control this device to move in a straight line and approach the flywheel. The outer wall of the bottom ring 106 will contact the outer wall of the flywheel and push the bottom ring 106, thereby pushing the sliding plate 114 with a certain force by pushing the air.

[0045] S2: During the process of air being introduced into the air guide cavity 113, when the pressure increases to a certain level, the air can enter the outside through the gap between the outer surface of the sealing plate 302 and the rotating shell 112, thereby maintaining the pressure in the air guide cavity 113 within a certain range.

[0046] S3: After the grinding block 115 contacts the hole wall and applies appropriate force, the motor 201 can be started to grind the hole wall while rotating and moving up and down. During the reset process of the pressure plate 104, air will be ejected from the nozzle 120 and finally hit the surface of the grinding block 115 and other structures.

[0047] One specific application of this embodiment is:

[0048] When using this device, first install it onto a robotic arm or other control device. When grinding the flywheel hole wall, position the device directly opposite the hole to be ground on the flywheel. Then, control the device to move linearly towards the flywheel, causing the rotating housing 112 to enter the hole. As the device continues to move, the outer wall of the bottom ring 106 will contact the outer wall of the flywheel, pushing the bottom ring 106. During this movement, the bottom ring 106 will move the pressure plate 104 via the connecting rod 105. During this movement, the pressure plate 104 will compress the spring 108 and push the air in the fixed housing 107 into the air guide hose 109. The air guide hose 109 will then guide the air into the sealing ring 110. The air entering the sealing ring 110 will then enter the air guide chamber 113. The air in 13 will push several sliding plates 114 in a direction away from each other. During the movement of the sliding plates 114, they will drive the grinding block 115 and the bending plate 116 to move together. During the movement of the bending plate 116, the ring spring 117 will be stretched. After the grinding block 115 moves a certain distance, its outer wall will contact the hole wall. As air continues to be input into the air guide chamber 113, the pressure in the air guide chamber 113 will increase, which will give the sliding plate 114 a certain force. This force will be evenly applied to the sliding plate 114. This design can give the sliding plate 114 a uniform force through air, ensuring that the contact force between the grinding block 115 and the hole wall is evenly distributed, which helps to avoid uneven wear or hole wall damage caused by excessive local force.

[0049] During the movement of the pressure plate 104, it also draws air from the second air guide hose 118 into the interior of the fixed housing 107. The second air guide hose 118 draws air out of the second air guide chamber 119, which then draws in external air through the nozzle 120 to compensate for the air entering the fixed housing 107. After the grinding process is completed and the device moves away from the flywheel, the pressure plate 104 will reset under the action of the first spring 108. During the reset process, the pressure plate 104 will push the air drawn into the fixed housing 107 back into the air guide chamber 107. In the second air hose 118, the second air hose 118 will introduce air into the second air chamber 119. The air entering the second air chamber 119 will be ejected again from the nozzle 120. The ejected air will flow at a certain angle and finally hit the surface of the grinding block 115 and other structures. This design can clean the dust attached to the surface of the grinding block 115 and other structures by the air ejected from the nozzle 120, keeping the device clean. At the same time, the grinding block 115 can make more even contact with the hole wall during the subsequent grinding process.

[0050] After the grinding block 115 contacts the hole wall and applies appropriate force, the motor 201 can be started to grind the hole wall. During this process, after the motor 201 starts, it will drive the rotating column 203 to rotate via the rotating shaft 202. During the rotation of the rotating column 203, it will drive the sliding ring 204 to move through the sliding groove on its outer surface. Under the limiting action of the fixed rod 102, the sliding ring 204 will move up and down along the sliding groove on the rotating column 203. During the rotation of the rotating column 203, it will drive the rotating shell 112 to rotate as a whole via the rotating rod 2031, thereby grinding the hole wall through the grinding block 115. During the up-and-down reciprocating movement of 04, it will drive the lifting plate 206 to move up and down in sync through the connecting rod 205. The lifting plate 206 will drive the rotating shell 112 to move up and down in sync through the connecting sleeve 207. This allows the grinding block 115 to move up and down in sync while rotating and grinding the hole wall. This design allows the contact point of the grinding block 115 on the hole wall to change continuously through the action of rotating and moving up and down, ensuring that the entire hole wall can be fully ground, improving the uniformity of grinding, making the hole wall surface smoother and flatter, and also making the wear of the grinding block 115 itself evenly distributed.

[0051] During the process of air being introduced into the air guide cavity 113, the pressure inside the air guide cavity 113 will continue to increase as air is continuously input. When the pressure increases to a certain level, the sealing plate 302 will overcome the elastic force of the spring 303 and move downward. When the sealing plate 302 moves to the point of separating from the inner wall of the rotating shell 112, the air in the air guide cavity 113 can enter the fixing frame 301 through the gap between the outer surface of the sealing plate 302 and the rotating shell 112, and can also enter the outside through the through hole opened on the outer wall of the fixing frame 301, thereby allowing the air in the air guide cavity 113 to enter the fixing frame 301. The pressure is maintained within a certain range. By rotating the threaded rod 305, the adjusting plate 304 can be moved upward to compress the second spring 303. This causes the sealing plate 302 to require greater force to overcome the elasticity of the second spring 303 and separate from the rotating shell 112. In this way, the pressure range in the air guide chamber 113 can be adjusted. This design can maintain the pressure in the air guide chamber 113 within a certain range, preventing excessive pressure from causing the grinding block 115 to apply too much force to the hole wall, resulting in excessive cutting of the hole wall material by the grinding block 115 in a short period of time, causing over-grinding.
