Technical Field

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

[0002] With the widespread application of diesel engines, the wear and damage of flywheel holes have become common problems. Traditional reaming methods usually rely on large machine tools, which limits the flexibility and efficiency of on-site operations. Therefore, the development of portable reaming devices can quickly and efficiently perform precise processing of flywheels on site, meet the needs of industrial maintenance, construction and emergency services, improve work efficiency and reduce maintenance costs.

[0003] In the process of reaming a flywheel, a large amount of strip-shaped metal debris is often generated, and these debris will remain on the surface of the flywheel. If these residual debris are not cleaned before the next reaming, the debris may interfere with the reaming position, which will not only cause inaccurate positioning of the reaming hole, but also affect the reaming accuracy, and thus affect the performance and reliability of the entire flywheel. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a portable diesel engine flywheel reaming device, comprising a blow-off assembly, the blow-off assembly comprising a bending plate, the inner wall of the bending plate is slidably connected to a sliding frame, and the inner wall of the sliding frame is rotatably connected to a threaded rod;

[0005] The limiting assembly includes a second air guide hose disposed above the second air guide hose, one end of the second air guide hose close to the left side is fixedly connected to a sliding sleeve, and the inner wall of the sliding sleeve is slidably connected to two connecting rods;

[0006] The adsorption component comprises an air guide hose 3 fixedly connected to the outer wall of the bending plate, a fixed shell 2 fixedly connected to the left side of the bending plate, and a sealing sleeve slidably connected to the inner wall of the fixed shell 2.

[0007] Preferably, a handle is fixedly connected to the left side of the threaded rod, the outer surface of the threaded rod is threadedly connected to the inner wall of the curved plate, the right side of the sliding frame is fixedly connected to a fixed plate, the top of the fixed plate is fixedly connected to a fixed shell, and the top of the fixed plate is fixedly connected to an electric push-pull rod. When using this device, first turn the handle to drive the threaded rod to rotate according to the length of the hole to be drilled from the outermost side of the flywheel, thereby driving the sliding frame and the fixed plate to move a certain distance to the right, and then place the device at the designated position of the flywheel.

[0008] Preferably, a lifting plate is fixedly connected to the bottom of the output end of the electric push-pull rod, the outer surface of the output end of the electric push-pull rod is slidably connected to the inner wall of the fixed plate, a drill bit is fixedly connected to the bottom of the lifting plate, a sliding rod is fixedly connected to the top of the lifting plate, the outer surface of the sliding rod is slidably connected to the inner wall of the fixed plate, and a pressure plate is fixedly connected to the top of the sliding rod. Then the electric push-pull rod is started to drive the lifting plate to move downward. During the downward movement of the lifting plate, the drill bit and the sliding rod will be driven to move together, and the sliding rod will drive the pressure plate to move downward together.

[0009] Preferably, the outer surface of the pressure plate is slidingly connected to the inner wall of the fixed shell, the bottom of the fixed plate is fixedly connected to an air guide hose, the end of the air guide hose away from the fixed plate is fixedly connected to an air guide ring, the inner wall of the air guide ring is fixedly connected to the outer wall of the drill bit, and the bottom of the air guide ring is fixedly connected to a nozzle. The pressure plate will compress the air in the fixed shell during the downward movement, and push the air into the air guide hose, the air guide hose will pass the air into the air guide ring, the air guide ring will pass the air into the nozzle, and finally the air will be ejected from the bottom nozzle of the nozzle, and the ejected air will hit the position where the flywheel is to be drilled. This design can blow away the debris that may exist at the position where the hole is to be drilled by the ejected air, so as to prevent the debris from affecting the accuracy of subsequent drilling, thereby affecting the performance and reliability of the entire flywheel.

[0010] Preferably, the air guide hose 2 is fixedly connected to the top of the fixed shell 1 at one end away from the handle, a spring 1 is provided inside the sliding sleeve, and the two connecting rods are fixedly connected to the front and back sides of the spring 1 on the sides close to each other, and the two connecting rods are fixedly connected to a clamping block on the sides away from each other, and the inner wall of the clamping block is slidably connected to the limit rod, and the right side of the limit rod is fixedly connected to the left side of the sliding frame. During the downward movement of the pressure plate, it will also suck the air in the air guide hose 2 into the interior of the fixed shell 1 through negative pressure, and the air guide hose 2 will suck the air in the sliding sleeve into the interior of the air guide hose 2, thereby generating negative pressure inside the sliding sleeve, and the generated negative pressure will pull the two connecting rods in a direction close to each other and compress the spring 1. During the movement, the two connecting rods will drive the two clamping blocks to move in a direction close to each other, thereby clamping and fixing the handle. This design can prevent the threaded rod from rotating during the reaming process, resulting in a deviation in the reaming position, by clamping and fixing the handle.

[0011] Preferably, the air guide hose three is fixedly connected to the top of the fixed shell one at the end away from the bending plate, a through hole is opened on the outer wall of the sealing sleeve, a spring two is fixedly connected to the top of the sealing sleeve, the top of the spring two is fixedly connected to the top of the inner wall of the fixed shell two, a one-way valve is fixedly connected to the inner wall of the sealing sleeve, an air guide hose four is fixedly connected to the top of the fixed shell two, the air guide hose four is fixedly connected to the fixed sleeve at the end away from the fixed shell two, and the bottom of the fixed sleeve is fixedly connected to an upper clamping plate. In the process of the pressure plate moving downward, it will also suck the air in the air guide hose three into the interior of the fixed shell one through negative pressure, and the air guide hose three will suck out the air in the fixed shell two, thereby generating negative pressure in the fixed shell two. Since the spring two will provide a downward thrust to the sealing sleeve, the sealing sleeve will not move upward immediately. At this time, the fixed shell two will suck out the air in the air guide hose four through the negative pressure, and the air guide hose four will suck out the air in the fixed sleeve.

[0012] Preferably, the top of the upper splint is fixedly connected to the bottom of the bent plate, the bottom of the upper splint is fixedly connected to a fixing rod, the inner wall of the fixing sleeve is slidably connected to a lifting rod, the outer surface of the lifting rod is slidably connected to the inner wall of the upper splint, the bottom of the lifting rod is fixedly connected to the lower splint, the inner wall of the lower splint is slidably connected to the outer surface of the fixing rod, the bottom of the fixed shell second is fixedly connected to an air guide hose five, the end of the air guide hose five is fixedly connected to the bottom of the lower splint at a distance from the fixed shell second, the outer wall of the air guide hose five is fixedly connected to an air guide branch pipe, the end of the air guide branch pipe is connected to the top of the upper splint at a distance from the air guide hose five The two parts are fixedly connected. After the air in the fixed sleeve is sucked out, an upward pulling force can be applied to the lifting rod, which will drive the lower clamping plate to move upward together, and then clamp the flywheel through the lower clamping plate and the upper clamping plate. At this time, as the air in the fixed shell 2 is continuously sucked out, the sealing sleeve will move upward due to the negative pressure overcoming the elastic force of the spring 2. When the sealing sleeve moves upward for a certain distance, the through hole will be exposed inside the fixed shell 2. At this time, the air in the air guide hose 5 can be sucked out through the through hole, and the one-way valve only allows air to enter the air guide hose 5 from the fixed shell 2. This design can use the sealing sleeve to make the upper and lower clamps clamp the flywheel before the air in the air guide hose 5 can be sucked into the fixed shell 2, so as to prevent the external air from being sucked into the flywheel during the subsequent adsorption, resulting in insufficient adsorption force. After the air in the air guide hose 5 is sucked into the fixed shell 2, the air guide hose 5 will suck out the air inside the lower clamp, thereby generating negative pressure in the lower clamp. Due to the negative pressure, the adsorption port on the top of the lower clamp will generate an adsorption force on the clamped flywheel, and at the same time, the air guide hose 5 will also pass through the guide The air branch tube sucks out the air in the upper splint. Similar to the above process, the suction port at the bottom of the upper splint will also generate an suction force on the flywheel. At this time, the drill bit can be driven to rotate, and the drill bit continues to be pushed downward to ream a hole in the flywheel. In the process of the drill bit drilling downward, the suction force generated by the upper and lower splints will become larger and larger. This design can use the suction force generated by the upper and lower splints on the flywheel to allow the device to be firmly installed on the flywheel, thereby preventing the entire device from shifting during the reaming process, resulting in reduced reaming accuracy.

[0013] A method for using a portable diesel engine flywheel reaming device comprises the following steps:

[0014] S1: After rotating the threaded rod to adjust the overall position of the fixed plate, place the device on the flywheel, then start the electric push-pull rod to drive the lifting plate to move downward, so that air is sprayed out from the nozzle;

[0015] S2: When the pressing plate moves downward, it will suck out the air in the sliding sleeve through negative pressure, and the two connecting rods will approach each other, thereby making the two clamping blocks approach each other to clamp the handle;

[0016] S3: When the pressure plate moves downward, negative pressure will be generated in the fixed shell 2, and the upper clamping plate will be subjected to an upward pulling force to clamp the flywheel. Then the sealing sleeve will move upward due to the negative pressure, and the clamping plate and the lower clamping plate will generate adsorption force on the flywheel.

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

[0018] 1. The present invention starts the electric push-pull rod to drive the lifting plate to move downward. During the downward movement, the lifting plate will drive the drill bit and the sliding rod to move together. During the movement, the sliding rod will drive the pressing plate to move downward together. During the downward movement, the pressing plate will compress the air in the fixed shell 1 and push the air into the air guide hose 1. The air guide hose 1 will pass the air into the air guide ring, and the air guide ring will pass the air into the nozzle. Finally, the air will be ejected from the bottom nozzle of the nozzle. The ejected air will hit the position where the flywheel is to be reamed. This design can blow away the debris that may exist at the position where the hole is to be reamed through the ejected air, so as to prevent the debris from affecting the accuracy of subsequent reaming, thereby affecting the performance and reliability of the entire flywheel.

[0019] 2. In the process of the downward movement of the pressure plate of the present invention, it will also suck the air in the air guide hose 2 into the interior of the fixed shell 1 through negative pressure, and the air guide hose 2 will suck the air in the sliding sleeve into the interior of the air guide hose 2, thereby generating negative pressure inside the sliding sleeve. The generated negative pressure will pull the two connecting rods towards each other and compress the spring 1. The two connecting rods will drive the two clamping blocks to move towards each other during the movement, thereby clamping and fixing the handle. This design can prevent the threaded rod from rotating during the reaming process, causing the reaming position to shift, by clamping and fixing the handle.

[0020] 3. In the process of the downward movement of the pressure plate of the present invention, the air in the air guide hose 3 is sucked into the interior of the fixed shell 1 through negative pressure, and the air guide hose 3 sucks out the air in the fixed shell 2, thereby generating negative pressure in the fixed shell 2. Since the spring 2 provides a downward thrust to the sealing sleeve, the sealing sleeve will not move upward immediately. At this time, the fixed shell 2 will suck out the air in the air guide hose 4 through negative pressure, and the air guide hose 4 will suck out the air in the fixed sleeve, thereby giving an upward pulling force to the lifting rod, and the lifting rod will drive the lower clamping plate 1 to move upward together, thereby pressing the flywheel through the lower clamping plate and the upper clamping plate. The air in the air guide hose 5 is clamped, and as the air in the fixed shell 2 continues to be sucked out, the sealing sleeve will move upward due to the negative pressure overcoming the elastic force of the spring 2. When the sealing sleeve moves upward for a certain distance, the through hole will be exposed inside the fixed shell 2. At this time, the air in the air guide hose 5 can be sucked out through the through hole, and the one-way valve only allows air to enter the air guide hose 5 from the fixed shell 2. This design can use the sealing sleeve to clamp the flywheel with the upper clamping plate and the lower clamping plate before the air in the air guide hose 5 can be sucked into the fixed shell 2, thereby preventing the external air from being sucked in during the subsequent adsorption of the flywheel, resulting in insufficient adsorption force.

[0021] 4. After the air in the air guide hose 5 of the present invention is sucked into the fixed shell 2, the air guide hose 5 will suck out the air inside the lower clamp, thereby generating negative pressure in the lower clamp. Due to the effect of the negative pressure, the suction port at the top of the lower clamp will generate an suction force on the clamped flywheel. At the same time, the air guide hose 5 will also suck out the air in the upper clamp through the air guide branch pipe. Similar to the above process, the suction port at the bottom of the upper clamp will also generate an suction force on the flywheel. At this time, the drill bit can be driven to rotate, and the drill bit is continuously pushed downward to drill a hole in the flywheel. In the process of the drill bit drilling downward, the suction force generated by the upper clamp and the lower clamp will become larger and larger. This design can enable the device to be stably installed on the flywheel through the suction force generated by the upper clamp and the lower clamp on the flywheel, thereby preventing the entire device from being offset during the drilling process, thereby reducing the drilling accuracy.

[0034] For example, see Figure 1 - Figure 3 The present invention is a portable diesel engine flywheel reaming device, comprising a blow-off assembly 1, the blow-off assembly 1 comprising a bending plate 101, the inner wall of the bending plate 101 is slidably connected to a sliding frame 102, and the inner wall of the sliding frame 102 is rotatably connected to a threaded rod 103;

[0035] The limiting assembly 2 includes a second air guide hose 201 disposed above the second air guide hose 201, a sliding sleeve 202 is fixedly connected to one end of the second air guide hose 201 close to the left side, and two connecting rods 203 are slidably connected to the inner wall of the sliding sleeve 202;

[0037] A handle 104 is fixedly connected to the left side of the threaded rod 103, and the outer surface of the threaded rod 103 is threadedly connected to the inner wall of the curved plate 101, and a fixed plate 105 is fixedly connected to the right side of the sliding frame 102. A fixed shell 106 is fixedly connected to the top of the fixed plate 105, and an electric push-pull rod 107 is fixedly connected to the top of the fixed plate 105. When using this device, first turn the handle 104 to drive the threaded rod 103 to rotate according to the length of the hole to be drilled from the outermost side of the flywheel, thereby driving the sliding frame 102 and the fixed plate 105 to move a certain distance to the right, and then place this device at the specified position of the flywheel.

[0038] A lifting plate 108 is fixedly connected to the bottom of the output end of the electric push-pull rod 107, and the outer surface of the output end of the electric push-pull rod 107 is slidably connected to the inner wall of the fixed plate 105. A drill bit 109 is fixedly connected to the bottom of the lifting plate 108, and a sliding rod 110 is fixedly connected to the top of the lifting plate 108. The outer surface of the sliding rod 110 is slidably connected to the inner wall of the fixed plate 105, and a pressing plate 111 is fixedly connected to the top of the sliding rod 110. Then the electric push-pull rod 107 is started to drive the lifting plate 108 to move downward. During the downward movement of the lifting plate 108, the drill bit 109 and the sliding rod 110 will be driven to move together, and the sliding rod 110 will drive the pressing plate 111 to move downward together.

[0039] The outer surface of the pressing plate 111 is slidably connected to the inner wall of the fixed shell 106, and an air guide hose 112 is fixedly connected to the bottom of the fixed plate 105. The air guide hose 112 is fixedly connected to an air guide ring 113 at the end away from the fixed plate 105. The inner wall of the air guide ring 113 is fixedly connected to the outer wall of the drill bit 109, and the bottom of the air guide ring 113 is fixedly connected to a nozzle 114. The pressing plate 111 will compress the air in the fixed shell 106 during the downward movement, and push the air into the air guide hose 112. The air guide hose 112 will pass the air into the air guide ring 113, and the air guide ring 113 will pass the air into the nozzle 114. Finally, the air will be ejected from the bottom nozzle of the nozzle 114, and the ejected air will hit the position where the flywheel is to be drilled. This design can blow away the debris that may exist at the position where the hole is to be drilled through the ejected air, so as to prevent the debris from affecting the accuracy of subsequent drilling, thereby affecting the performance and reliability of the entire flywheel.

[0040] For example 2, please refer to Figure 4 - Figure 8 The present invention is a portable diesel engine flywheel reaming device. On the basis of Example 1, the air guide hose 201 is fixedly connected to the top of the fixed shell 106 at one end away from the handle 104, and a spring 204 is arranged inside the sliding sleeve 202. Two connecting rods 203 are fixedly connected to the front and back of the spring 204 on the side close to each other, and the two connecting rods 203 are fixedly connected to the clamping block 205 on the side away from each other. The inner wall of the clamping block 205 is slidably connected to the limit rod 206. The right side of the limit rod 206 is fixedly connected to the left side of the sliding frame 102. When the pressure plate 111 moves downward, it will also push the air guide hose 2 through negative pressure. The air in 201 is sucked into the interior of the fixed shell 106, and the air guide hose 201 will suck the air in the sliding sleeve 202 into the interior of the air guide hose 201, thereby generating negative pressure inside the sliding sleeve 202. The generated negative pressure will pull the two connecting rods 203 towards each other and compress the spring 1 204. The two connecting rods 203 will drive the two clamping blocks 205 to move towards each other during the movement, thereby clamping and fixing the handle 104. This design can prevent the threaded rod 103 from rotating during the reaming process, causing the reaming position to shift, by clamping and fixing the handle 104.

[0041] The air guide hose 301 is fixedly connected to the top of the fixed shell 106 at one end away from the bending plate 101, a through hole 304 is opened on the outer wall of the sealing sleeve 303, a spring 2 305 is fixedly connected to the top of the sealing sleeve 303, the top of the spring 2 305 is fixedly connected to the top of the inner wall of the fixed shell 2 302, a one-way valve 306 is fixedly connected to the inner wall of the sealing sleeve 303, an air guide hose 4 307 is fixedly connected to the top of the fixed shell 2 302, the air guide hose 4 307 is fixedly connected to the fixed sleeve 308 at one end away from the fixed shell 2 302, and an upper clamp is fixedly connected to the bottom of the fixed sleeve 308 Plate 309, during the downward movement of the pressure plate 111, it will also suck the air in the air hose three 301 into the interior of the fixed shell one 106 through negative pressure, and the air hose three 301 will suck out the air in the fixed shell two 302, thereby generating negative pressure in the fixed shell two 302. Since the spring two 305 will provide a downward thrust to the sealing sleeve 303, the sealing sleeve 303 will not move upward immediately. At this time, the fixed shell two 302 will suck out the air in the air hose four 307 through negative pressure, and the air hose four 307 will suck out the air in the fixed sleeve 308.

[0042] The top of the upper clamping plate 309 is fixedly connected to the bottom of the bending plate 101, and the bottom of the upper clamping plate 309 is fixedly connected to a fixing rod 310, and the inner wall of the fixing sleeve 308 is slidably connected to a lifting rod 311, and the outer surface of the lifting rod 311 is slidably connected to the inner wall of the upper clamping plate 309, and the bottom of the lifting rod 311 is fixedly connected to a lower clamping plate 312, and the inner wall of the lower clamping plate 312 is slidably connected to the outer surface of the fixing rod 310, and the bottom of the fixed shell 2 302 is fixedly connected to a gas guide hose 5 313, and the gas guide hose 5 313 ​​is fixedly connected to the bottom of the lower clamping plate 312 at one end away from the fixed shell 2 302, and the outer wall of the gas guide hose 5 313 ​​is fixedly connected to the gas guide branch pipe 314, and the gas guide branch pipe 314 is at a distance away from the gas guide One end of the hose 5 313 ​​is fixedly connected to the top of the upper clamping plate 309. After the air in the fixed sleeve 308 is sucked out, an upward pulling force can be given to the lifting rod 311, and the lifting rod 311 will drive the lower clamping plate 312 to move upward together, and then the flywheel is clamped by the lower clamping plate 312 and the upper clamping plate 309. At this time, as the air in the fixed shell 2 302 continues to be sucked out, the sealing sleeve 303 will move upward due to the negative pressure overcoming the elastic force of the spring 2 305. When the sealing sleeve 303 moves upward for a certain distance, the through hole 304 will be exposed inside the fixed shell 2 302. At this time, the air in the air guide hose 5 313 ​​can be sucked out through the through hole 304, and the one-way valve 306 only Air is allowed to enter the air guide hose five 313 from the fixed shell two 302. This design can make the air in the air guide hose five 313 be sucked into the fixed shell two 302 only after the upper clamping plate 309 and the lower clamping plate 312 clamp the flywheel through the effect of the sealing sleeve 303, so as to prevent the external air from being sucked in during the subsequent adsorption of the flywheel, resulting in insufficient adsorption force. After the air in the air guide hose five 313 is sucked into the fixed shell two 302, the air guide hose five 313 will suck out the air inside the lower clamping plate 312, thereby generating negative pressure in the lower clamping plate 312. Due to the effect of the negative pressure, the adsorption port on the top of the lower clamping plate 312 will generate an adsorption force on the clamped flywheel. At the same time, the air guide hose 313 will also suck out the air in the upper clamp 309 through the air guide branch pipe 314. Similar to the above process, the suction port at the bottom of the upper clamp 309 will also generate an suction force on the flywheel. At this time, the drill bit 109 can be driven to rotate, and the drill bit 109 can continue to be pushed downward to drill a hole in the flywheel. In the process of the drill bit 109 drilling downward, the suction force generated by the upper clamp 309 and the lower clamp 312 will become larger and larger. This design can use the suction force generated by the upper clamp 309 and the lower clamp 312 on the flywheel to ensure that the device can be stably installed on the flywheel, thereby preventing the entire device from shifting during the drilling process, thereby reducing the drilling accuracy.

[0043] The method for using the flywheel reaming device comprises the following steps:

[0044] S1: After rotating the threaded rod 103 to adjust the overall position of the fixing plate 105, the device is placed on the flywheel, and then the electric push-pull rod 107 is started to drive the lifting plate 108 to move downward, thereby causing the nozzle 114 to spray air;

[0045] S2: When the pressing plate 111 moves downward, it will suck out the air in the sliding sleeve 202 through negative pressure, and the two connecting rods 203 will approach each other, thereby making the two clamping blocks 205 approach each other to clamp the handle 104;

[0046] S3: When the pressure plate 111 moves downward, negative pressure will be generated in the fixed shell 2 302, and the upper clamping plate 309 will be subjected to an upward pulling force to clamp the flywheel. Then the sealing sleeve 303 will move upward due to the negative pressure, and the upper clamping plate 309 and the lower clamping plate 312 will generate adsorption force on the flywheel.

[0047] A specific application of this embodiment is:

[0048] When using the device, first according to the distance between the position to be reamed and the outermost side of the flywheel, turn the handle 104 to drive the threaded rod 103 to rotate, and then drive the sliding frame 102 and the fixed plate 105 to move to the right a certain distance, so that when reaming the hole later, the drill bit 109 can face the position to be reamed, and then place the device at the specified position of the flywheel, and make the flywheel between the upper clamping plate 309 and the lower clamping plate 312, and then start the electric push-pull rod 107 to drive the lifting plate 108 to move downward, and the lifting plate 108 will drive the drill bit 109 and the sliding rod 110 to move together during the downward movement. During the movement, the pressure plate 111 will be driven to move downward together. During the downward movement, the pressure plate 111 will compress the air in the fixed shell 106 and push the air into the air guide hose 112. The air guide hose 112 will pass the air into the air guide ring 113. The air guide ring 113 will pass the air into the nozzle 114. Finally, the air will be ejected from the bottom nozzle of the nozzle 114. The ejected air will hit the position where the flywheel is to be reamed. This design can blow away the debris that may exist at the position where the hole is to be reamed through the ejected air, so as to prevent the debris from affecting the accuracy of subsequent reaming, thereby affecting the performance and reliability of the entire flywheel.

[0049] When the pressing plate 111 moves downward, it will also suck the air in the second air guide hose 201 into the interior of the fixed shell 106 through negative pressure, and the second air guide hose 201 will suck the air in the sliding sleeve 202 into the interior of the second air guide hose 201, thereby generating negative pressure inside the sliding sleeve 202, and the generated negative pressure will pull the two connecting rods 203 in a direction close to each other and compress the spring 1 204, and the two connecting rods 203 will drive the two clamping blocks 205 to move in a direction close to each other during the movement, thereby clamping and fixing the handle 104. This design can prevent the threaded rod 103 from rotating during the reaming process, resulting in the displacement of the reaming position, by clamping and fixing the handle 104.

[0050] When the pressure plate 111 moves downward, it will also suck the air in the air hose 301 into the fixed shell 106 through negative pressure, and the air hose 301 will suck out the air in the fixed shell 2 302, thereby generating negative pressure in the fixed shell 2 302. Since the spring 2 305 will provide a downward thrust to the sealing sleeve 303, the sealing sleeve 303 will not move upward immediately. At this time, the fixed shell 2 302 will suck out the air in the air hose 4 307 through negative pressure, and the air hose 4 307 will suck out the air in the fixed sleeve 308, thereby giving an upward pulling force to the lifting rod 311, and the lifting rod 311 will drive the lower clamping plate 312 to move upward together, thereby exerting a positive force on the flywheel through the lower clamping plate 312 and the upper clamping plate 309. The air in the second fixed shell 302 is clamped. At this time, as the air in the second fixed shell 302 is continuously sucked out, the sealing sleeve 303 will move upward due to the negative pressure overcoming the elastic force of the second spring 305. When the sealing sleeve 303 moves upward for a certain distance, the through hole 304 will be exposed inside the second fixed shell 302. At this time, the air in the fifth air guide hose 313 can be sucked out through the through hole 304. The one-way valve 306 only allows air to enter the fifth air guide hose 313 from the second fixed shell 302. This design can make the air in the fifth air guide hose 313 be sucked into the second fixed shell 302 only after the upper clamping plate 309 and the lower clamping plate 312 clamp the flywheel through the effect of the sealing sleeve 303, so as to prevent the inhalation of external air when the flywheel is subsequently adsorbed, resulting in insufficient adsorption force.

[0051] In the above process, after the air in the air guide hose 5 313 ​​is sucked into the fixed shell 2 302, the air guide hose 5 313 ​​will suck out the air inside the lower clamping plate 312, thereby generating negative pressure in the lower clamping plate 312. Due to the effect of the negative pressure, the suction port at the top of the lower clamping plate 312 will generate a suction force on the clamped flywheel. At the same time, the air guide hose 5 313 ​​will also suck out the air in the upper clamping plate 309 through the air guide branch pipe 314. Similar to the above process, the suction port at the bottom of the upper clamping plate 309 will also An adsorption force is generated on the flywheel, and the drill bit 109 can be driven to rotate at this time, while the drill bit 109 continues to be pushed downward to drill a hole in the flywheel. In the process of the drill bit 109 drilling downward, the adsorption force generated by the upper clamping plate 309 and the lower clamping plate 312 will become larger and larger. This design can use the adsorption force generated by the upper clamping plate 309 and the lower clamping plate 312 on the flywheel to allow the device to be stably installed on the flywheel, thereby preventing the entire device from shifting during the reaming process, resulting in reduced reaming accuracy.
