Technical Field

[0001] The invention relates to the technical field of hole wall grinding, in particular to a diesel engine flywheel hole wall grinding device and a use method thereof. Background Art

[0002] In the manufacturing and maintenance process of diesel engines, the flywheel is a key component, and the quality of its hole wall directly affects the performance and reliability of the engine. The flywheel hole wall may have defects such as unevenness and burrs due to insufficient processing accuracy, wear or other factors. These defects will not only affect the balance of the flywheel, but may also cause vibration and noise when running at high speeds. Therefore, it is crucial to effectively grind the flywheel hole wall.

[0003] When using a hole wall grinding device, the grinding head on it can usually be adjusted to adapt to 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 enough, resulting in uneven pressure distribution when the grinding head contacts the hole wall. This uneven force will lead to differences in grinding effects, causing some areas to be over-ground while other areas may not be worn enough, ultimately affecting the flatness and finish of the hole wall. In response to the above problems, the following solutions are proposed. Summary of the invention

When using this device, first install this device on a control device such as a mechanical arm. When the flywheel hole wall is to be polished, the device is placed facing the hole to be polished on the flywheel, and then the device is controlled to move linearly close to the flywheel, so that the rotating shell enters the hole as a whole. 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 1. During the movement, the pressure plate will compress the spring 1 and push the air in the fixed shell into the air guide hose 1.

[0008] Preferably, an air guide hose is fixedly connected to a sealing ring at one end away from the fixed shell, a fixing column is fixedly connected to the top of the sealing ring, a rotating shell is slidably connected to the outer surface of the sealing ring, an air guide cavity is opened inside the rotating shell, a sliding plate is slidably connected to the inner wall of the rotating shell, a grinding block is fixedly connected to the inner wall of the sliding plate, a bending plate is fixedly connected to the top and bottom of the sliding plate, an annular spring is contacted to the inner wall of the bending plate, the air guide hose will pass air into the sealing ring, the air passed into the sealing ring will enter the air guide cavity, the air entering the air guide cavity will push the plurality of sliding plates in the direction away from each other, and the sliding plate When the moving plate moves, it will drive the grinding block and the bending plate to move together. When the bending plate moves, the annular spring will be stretched. After the grinding block moves a certain distance, its outer wall will contact the hole wall. As the air is continuously input into the air guide cavity, the pressure in the air guide cavity will increase, thereby giving the sliding plate a certain thrust, and the thrust will act evenly on the sliding plate. This design can give the sliding plate a uniform thrust through the air, ensuring that the contact force between the grinding block and the hole wall is evenly distributed, which helps to avoid uneven wear or hole wall damage caused by excessive local force.

[0009] Preferably, an air guide hose 2 is fixedly connected to the right side of the fixed shell, an air guide cavity 2 is opened inside the bottom ring, and a nozzle is fixedly connected to the top of the bottom ring. During the movement of the pressing plate, it will also suck the air in the air guide hose 2 into the interior of the fixed shell, and the air guide hose 2 will suck out the air in the air guide cavity 2, and the air guide cavity 2 will suck in external air through the nozzle to compensate for the air entering the fixed shell. In the subsequent process of grinding the device away from the flywheel, the pressing plate will be reset under the action of spring 1. During the resetting of the pressing plate, it will push the air sucked into the fixed shell back into the air guide hose 2, and the air guide hose 2 will pass the air into the air guide cavity 2. The air entering the air guide cavity 2 will be ejected from the nozzle again, and the ejected air will flow at a certain inclination 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 sprayed by the nozzle, so that the device remains clean, and the grinding block can 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, the outer surface of the rotating column is slidably connected with a sliding ring, the inner wall of the sliding ring is slidably connected to the outer surface of the fixed rod, the bottom of the sliding ring is fixedly connected to a connecting rod 2, the bottom of the connecting rod 2 is fixedly connected to the lifting plate, and the bottom of the rotating column is fixedly connected to the rotating rod. After the above-mentioned grinding block contacts the hole wall and applies a suitable force, the motor can be started to grind the hole wall. In the above process, after the motor is started, the rotating column will be driven to rotate through the rotating shaft. During the rotation, the rotating column will drive the sliding ring to move through the sliding groove opened on its outer surface. The sliding ring will reciprocate up and down along the sliding groove opened on the rotating column under the limiting action of the fixed rod. During the rotation, the rotating column will drive the rotating shell as a whole to rotate through the rotating rod, and then grind the hole wall through the grinding block.

In the process of the sliding ring moving up and down reciprocatingly, it will drive the lifting plate to move up and down through the connecting rod 2, and the lifting plate will drive the rotating shell as a whole to move up and down through the connecting sleeve, so that the grinding block can also move up and down while rotating and grinding the hole wall.

In the process of the above-mentioned air passing into the air guide cavity one, with the continuous input of air, the pressure inside the air guide cavity one will continue to increase. When the pressure increases to a certain intensity, the sealing plate will overcome the elastic force of the spring two and move downward. When the sealing plate moves to separate from the inner wall of the rotating shell, the air in the air guide cavity one can pass through the outside of the sealing plate. The gap between the surface and the rotating shell enters the fixing frame, and can enter the outside world through the through hole opened in the outer wall of the fixing frame, so that the pressure in the air guide chamber 1 can be maintained within a certain range, and the adjustment plate can be driven to move upward by rotating the threaded rod to compress the spring 2, so that the sealing plate needs a greater force to overcome the elastic force of the spring 2 and separate from the rotating shell, and then the pressure range in the air guide chamber 1 can be adjusted. This design can maintain the pressure in the air guide chamber 1 within a certain range, prevent excessive pressure from causing the grinding block to exert excessive force on the hole wall, resulting in excessive cutting of the hole wall material by the grinding block in a short time, causing over-grinding.

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

[0014] S1: When using this device, first install this device on a control device such as a robotic arm, then control this device to move linearly close to the flywheel, the outer wall of the bottom ring will contact the outer wall of the flywheel and push the bottom ring, and then a certain force can be given to the sliding plate by pushing the air;

[0015] S2: During the process of the air passing into the first air guide cavity, 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 cavity 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 process of resetting 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 the flywheel hole wall is to be polished, the device is placed directly opposite to the hole to be polished on the flywheel, and then the device is controlled to move linearly close to the flywheel so that the rotating shell as a whole enters the hole. As the device continues to move, the outer wall of the bottom ring contacts the outer wall of the flywheel and pushes the bottom ring. When the bottom ring moves, it drives the pressure plate to move through the connecting rod. During the movement, the pressure plate compresses the spring and pushes the air in the fixed shell into the air guide hose. The air guide hose passes the air into the sealing ring. The air passed into the sealing ring enters the air guide cavity. The air entering the air guide cavity pushes the plurality of sliding plates toward The sliding plate is pushed in the direction away from each other, and the sliding plate will drive the grinding block and the bending plate to move together during the movement. The bending plate will stretch the annular spring during the movement. After the grinding block moves a certain distance, its outer wall will contact the hole wall. As the air is continuously input into the air guide cavity, the pressure in the air guide cavity will increase, thereby giving the sliding plate a certain thrust, and the thrust will act evenly on the sliding plate. This design can give the sliding plate a uniform thrust through the air, ensuring that the contact force between the grinding block and the hole wall is evenly distributed, which helps to avoid uneven wear or hole wall damage caused by excessive local force.

[0019] 2. In the process of movement of the pressure plate of the present invention, it will also suck the air in the second air guide hose into the interior of the fixed shell, and the second air guide hose will suck out the air in the second air guide chamber, and the second air guide chamber will suck in external air through the nozzle to compensate for the air entering the fixed shell. In the subsequent process of grinding the device away from the flywheel, the pressure plate will be reset under the action of the first spring. In the process of resetting the pressure plate, it will push the air sucked into the fixed shell back into the second air guide hose, and the second air guide hose will pass the air into the second air guide chamber, and the air entering the second air guide chamber will be ejected from the nozzle again. The ejected air will flow at a certain inclination 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, so that the device is kept clean, and the grinding block can contact the hole wall more evenly during the subsequent grinding process.

[0020] 3. In the present invention, after the grinding block contacts the hole wall and applies a suitable force, the motor can be started to grind the hole wall. In the above process, after the motor is started, it will drive the rotating column to rotate through the rotating shaft. During the rotation process, the rotating column will drive the sliding ring to move through the sliding groove provided on its outer surface. The sliding ring will reciprocate up and down along the sliding groove provided on the rotating column under the limiting action of the fixed rod. During the rotation process, the rotating column will drive the rotating shell as a whole to rotate through the rotating rod, and then the hole wall will be polished by the grinding block, while the sliding ring will reciprocate up and down. During the movement, it will drive the lifting plate to move back and forth up and down through the connecting rod 2, and the lifting plate will drive the rotating shell as a whole to move back and forth up and down through the connecting sleeve, so that the grinding block can also move back and forth up and down while rotating and grinding the hole wall. This design can make the contact point of the grinding block on the hole wall constantly change through the effect of the grinding block rotating and moving up and down, ensuring that the entire hole wall can be fully polished, improving the uniformity of polishing, making the surface of the hole wall smoother and flatter, and at the same time making the wear of the grinding block itself evenly distributed.

[0021] 4. In the process of air passing into the air guide chamber 1 of the present invention, with the continuous input of air, the pressure inside the air guide chamber 1 will continue to increase. When the pressure increases to a certain intensity, the sealing plate will overcome the elastic force of the second spring and move downward. When the sealing plate moves to separate from the inner wall of the rotating shell, the air in the air guide chamber 1 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 in the outer wall of the fixed frame, so that the pressure in the air guide chamber 1 can be maintained within a certain range. The adjustment plate can be driven to move upward to compress the second spring by rotating the threaded rod, so that the sealing plate needs a greater force to overcome the elastic force of the second spring and separate from the rotating shell, so as to adjust the pressure range in the air guide chamber 1. This design can maintain the pressure in the air guide chamber 1 within a certain range, thereby preventing excessive pressure from causing the grinding block to apply excessive force to the hole wall, resulting in excessive cutting of the hole wall material by the grinding block in a short time, causing excessive grinding.

When installing, first install the device on a control device such as a robotic arm. When grinding the flywheel hole wall, place the device opposite the hole to be ground on the flywheel, then control the device to move linearly close to the flywheel, so that the rotating shell 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 moving, the bottom ring 106 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 shell 107 into the air guide hose 109.

[0038] The air guide hose 109 is fixedly connected to a sealing ring 110 at one end away from the fixed shell 107, and a fixing column 111 is fixedly connected to the top of the sealing ring 110. The outer surface of the sealing ring 110 is slidably connected to a rotating shell 112, and an air guide cavity 113 is provided inside the rotating shell 112. A sliding plate 114 is slidably connected to the inner wall of the rotating shell 112, and a grinding block 115 is fixedly connected to the inner wall of the sliding plate 114.

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 annular spring 117 during the movement. After the grinding block 115 moves a certain distance, its outer wall will contact the hole wall.

In the subsequent grinding process of the device away from the flywheel, the pressure plate 104 will be reset under the action of the first spring 108. During the resetting process, the air sucked into the fixed shell 107 will be pushed back into the second air guide hose 118, and the second air guide hose 118 will pass the air into the second air guide cavity 119.

This design can clean the dust attached to the surface of the grinding block 115 and other structures through the air ejected from the nozzle 120, so that the device can be kept clean, and the grinding block 115 can contact the hole wall more evenly during the subsequent grinding process.

[0040] For example 2, please refer to Figure 6 - Figure 8The present invention is a diesel engine flywheel hole wall grinding device. On the basis of Example 1, the outer surface of the rotating shaft 202 is rotatably connected to the inner wall of the mounting plate 101, the outer surface of the rotating column 203 is slidably connected to the sliding ring 204, the inner wall of the sliding ring 204 is slidably connected to the outer surface of the fixed rod 102, the bottom of the sliding ring 204 is fixedly connected to the connecting rod 205, the bottom of the connecting rod 205 is fixedly connected to the lifting plate 206, and the bottom of the rotating column 203 is fixedly connected to the rotating rod 2031. After the above-mentioned grinding block 115 contacts the hole wall and applies a suitable force, the grinding can be started. The motor 201 grinds 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 opened on its outer surface. The sliding ring 204 will move back and forth up and down along the sliding groove opened in the rotating column 203 under the limiting action of the fixed rod 102. 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 grind the hole wall through the grinding 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. The bottom of the lifting plate 206 is fixedly connected with a connecting sleeve 207, 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. When the sliding ring 204 reciprocates up and down, it will drive the lifting plate 206 to reciprocate up and down through the connecting rod 205. The lifting plate 206 The connecting sleeve 207 will drive the rotating shell 112 to move up and down as a whole, so that the grinding block 115 can also move up and down while rotating and grinding the hole wall. This design can make the contact point of the grinding block 115 on the hole wall constantly change through the effect of the grinding block 115 rotating and moving up and down, ensuring that the entire hole wall can be fully polished, improving the uniformity of polishing, making the hole wall surface smoother and flatter, and at the same time making the wear of the grinding block 115 itself evenly distributed.

[0042] The top of the fixing 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, and the bottom of the spring 303 is fixedly connected with an adjustment plate 304, the outer surface of the adjustment plate 304 is slidably connected to the inner wall of the fixing frame 301, and the inner wall of the adjustment plate 304 is rotatably connected with a threaded rod 305, and the outer surface of the threaded rod 305 is threadedly connected to the inner wall of the fixing frame 301. In the process of the above-mentioned air passing into the air guide cavity 113, as the air is continuously input, the pressure inside the air guide cavity 113 will continue to increase. When the pressure increases to a certain intensity, the sealing plate 302 will overcome the elastic force of the spring 303 and move downward. When the sealing plate 302 moves to separate from the inner wall of the rotating shell 112, the air in the air guide cavity 113 can pass through The gap between the outer surface of the sealing plate 302 and the rotating shell 112 enters the fixing frame 301, and can enter the outside through the through hole opened on the outer wall of the fixing frame 301, so that the pressure in the air guide cavity 113 can be maintained within a certain range, and the adjustment plate 304 can be driven to move upward to compress the spring 2 303 by rotating the threaded rod 305, so that the sealing plate 302 needs a greater force to overcome the elastic force of the spring 2 303 and separate from the rotating shell 112, and then the pressure range in the air guide cavity 113 can be adjusted. This design can maintain the pressure in the air guide cavity 113 within a certain range, prevent 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 time, causing over-grinding.

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

[0044] S1: When using the device, first install the device on a control device such as a robotic arm, and then control the device to move linearly close to the flywheel. The outer wall of the bottom ring 106 will contact the outer wall of the flywheel and push the bottom ring 106, which can then give a certain force to the sliding plate 114 by pushing the air;

[0045] S2: During the process of the air passing 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 resetting 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] A specific application of this embodiment is:

[0048] When using the device, first install the device on a control device such as a robotic arm. When grinding the flywheel hole wall, place the device opposite to the hole to be ground on the flywheel, then control the device to move linearly close to the flywheel, so that the rotating shell 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 shell 107 into the air guide hose 109. The air guide hose 109 will pass the air into the sealing ring 110. The air passed into the sealing ring 110 will enter the air guide cavity 113 and enter the air guide cavity 114. The air in the air guide cavity 113 will push the sliding plates 114 in the direction away from each other. The sliding plates 114 will drive the grinding blocks 115 and the bending plates 116 to move together during the movement. The bending plates 116 will stretch the annular springs 117 during the movement. After the grinding blocks 115 move a certain distance, their outer walls will contact the hole wall. As the air is continuously input into the air guide cavity 113, the pressure in the air guide cavity 113 will increase, thereby giving the sliding plates 114 a certain thrust, and the thrust will act evenly on the sliding plates 114. This design can give the sliding plates 114 a uniform thrust through the air, ensuring that the contact force between the grinding blocks 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 pressing plate 104, the air in the second air guide hose 118 is sucked into the interior of the fixed shell 107. The second air guide hose 118 sucks out the air in the second air guide cavity 119. The second air guide cavity 119 sucks in external air through the nozzle 120 to compensate for the air entering the fixed shell 107. In the subsequent grinding process of the device away from the flywheel, the pressing plate 104 is reset under the action of the first spring 108. During the reset process of the pressing plate 104, the air sucked into the fixed shell 107 is pushed back into the air guide cavity 119. In the air hose 118, the air guide hose 118 will pass air into the air guide cavity 119, and the air entering the air guide cavity 119 will be ejected again from the nozzle 120. The ejected air will flow at a certain tilt 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 through the air ejected from the nozzle 120, so that the device is kept clean, and the grinding block 115 can contact the hole wall more evenly during the subsequent grinding process;

[0050] After the grinding block 115 contacts the hole wall and applies a suitable force, the motor 201 can be started to grind 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 process, the rotating column 203 will drive the sliding ring 204 to move through the sliding groove provided on its outer surface. The sliding ring 204 will reciprocate up and down along the sliding groove provided on the rotating column 203 under the limiting action of the fixed rod 102. During the rotation process, the rotating column 203 will drive the rotating shell 112 to rotate as a whole through the rotating rod 2031, and then the hole wall is polished by the grinding block 115, and the sliding ring 2 During the up and down reciprocating movement of 04, it will drive the lifting plate 206 to move up and down together through the connecting rod 205, and the lifting plate 206 will drive the rotating shell 112 to move up and down as a whole through the connecting sleeve 207, so that the grinding block 115 can also move up and down when rotating and grinding the hole wall. This design can make the contact point of the grinding block 115 on the hole wall constantly change through the effect of the grinding block 115 rotating and moving up and down, ensuring that the entire hole wall can be fully polished, improving the uniformity of polishing, making the hole wall surface smoother and flatter, and at the same time, it can also make the wear of the grinding block 115 itself evenly distributed;

[0051] In the process of the air being introduced into the air guide cavity 113, as the air is continuously input, the pressure inside the air guide cavity 113 will continue to increase. 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 separate 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 enter the outside through the through hole on the outer wall of the fixing frame 301, thereby making the air in the air guide cavity 113 The pressure is maintained within a certain range, and the adjustment plate 304 can be driven to move upward to compress the spring 2 303 by rotating the threaded rod 305, so that the sealing plate 302 needs a greater force to overcome the elastic force of the spring 2 303 and separate from the rotating shell 112, thereby adjusting the pressure range in the air guide cavity 113. This design can maintain the pressure in the air guide cavity 113 within a certain range, thereby 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 time, causing over-grinding.
