Description

Technical Field

[0001] This invention relates to the field of bore machining technology, specifically to bore machining equipment for electronic fuel injection motorcycle fuel pumps. Background Technology

[0002] The main function of the fuel pump in an electronic fuel injection motorcycle is to deliver fuel from the fuel tank to the engine's injectors. It works by using an electric motor to drive a small impeller or piston. When the motorcycle's electronic fuel injection system sends a start signal, the fuel pump motor starts running. The motor drives the impeller to rotate at high speed or the piston to reciprocate, causing the fuel to be pressurized inside the pump. Boring is a precise metalworking method, mainly used to enlarge, trim, or precisely machine existing holes. The internal structure of the fuel pump is relatively complex, requiring boring to create holes of various shapes and sizes to meet the design requirements of its internal oil passages, mounting bases, and other structures. Precise boring can provide accurate mounting positions and references for other components of the fuel pump, ensuring the assembly accuracy between various components.

[0003] Before drilling, the fuel pump of an electronically controlled fuel injection motorcycle needs to be cleaned to prevent impurities from entering the drilling area and affecting the drilling accuracy and quality. The flying debris generated during drilling of the fuel pump also needs to be treated. Therefore, we have proposed a bore hole processing device for electronically controlled fuel injection motorcycle fuel pumps. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a bore machining device for an electronically controlled fuel pump for motorcycles, comprising a worktable, a side plate fixedly connected to the top of the worktable, a three-panel fixedly connected to the top of the side plate, a bore tool fixedly connected to the top of the inner wall of the three-panel, a clamping device fixedly connected to one side of the side plate, a cleaning device slidably connected to the side of the side plate near the clamping device, an inclined groove formed on the top of the worktable, a rectangular groove formed on the inner wall of the inclined groove, a rectangular hole formed on one side of the inner wall of the rectangular groove, an air outlet formed on the inner side of the rectangular groove below the rectangular hole, a collecting device fixedly connected to the inner wall of the rectangular groove, and a collecting box fixedly connected to one side of the worktable;

[0005] The clamping device includes a motor, the drive shaft of which is fixedly connected to a T-shaped rod. A gear is sleeved and fixedly connected to one side of the T-shaped rod, and a rack is meshed with one side of the gear. A limit plate is fixedly connected to one end of the rack, and a connecting rod is fixedly connected to one side of the rack. A rectangular plate is fixedly connected to the end of the connecting rod away from the rack, and an electric push rod is fixedly connected to the side of the rectangular plate away from the connecting rod. An arc-shaped plate is fixedly connected to the drive shaft of the electric push rod, and a rubber strip is fixedly connected to the inner side of the arc-shaped plate. The rubber strip on the inner side of the arc-shaped plate contacts and presses against the fuel pump. The rough surface of the rubber strip increases the contact area and friction, effectively preventing the fuel pump from sliding and further enhancing the firmness of the fuel pump fixation. This ensures that the fuel pump will not be displaced by external forces during processing. A base plate is fixedly connected to the bottom of the rectangular plate away from the connecting rod. A circular groove is formed at the center of the top of the base plate. The circular groove restricts the electromagnetic chuck from swaying in all directions, avoiding displacement of the drilling position due to instability of the electromagnetic chuck and ensuring the accuracy of the drilling position. The top of the base plate has arc-shaped holes on both sides of the circular groove. These arc-shaped holes prevent the boring bar from contacting the base plate during drilling, avoiding damage to the tool or wear on the base plate caused by collisions, thus extending the service life of the tool and the base plate. A spring is fixedly connected to the bottom of the inner wall of the circular groove. When the borer vibrates during drilling, the spring is compressed, converting the vibration energy into elastic potential energy and storing it, thus acting as a buffer and protecting the fuel pump from damage that may be caused by excessive vibration. An electromagnetic chuck is fixedly connected to the top of the spring. The coil inside the electromagnetic chuck generates a magnetic field when energized, magnetizing the fuel pump and generating a suction force, which can firmly adhere the fuel pump to its surface, ensuring that the position of the fuel pump does not shift during processing. The top of the base plate has a circular hole. The side of the motor is fixedly connected to one side of the side plate. One end of the T-shaped rod passes through the side plate and is rotatably connected to it. The side of the rack away from the connecting rod is slidably connected to one side of the side plate. Multiple rubber strips are provided, and the multiple rubber strips are evenly distributed on the inner side of the arc-shaped plate.

[0006] Furthermore, the cleaning device includes a rack two, one side of which is rotatably connected to a rotating rod via a rotating bolt. A hollow cylinder is sleeved and fixedly connected to one side of the rotating rod, and a sponge tube is sleeved and fixedly connected to one side of the hollow cylinder. The surface of the sponge tube is rough, and when it contacts the surface of the fuel pump, the rotating rod rotates due to friction, thus rotating itself. During the rotation, it can remove oil stains from the surface of the fuel pump. Utilizing its own adsorption and friction, it effectively cleans oil stains adhering to the surface of the fuel pump. A brush is fixedly connected to one side of the sponge tube. When the brush rotates with the sponge tube, it directly contacts the surface of the fuel pump, reaching deep into the crevices and uneven areas of the fuel pump surface to effectively scrape away dust, rust, and other substances, further improving the surface finish of the fuel pump. To ensure effective cleaning and prevent dust particles from being carried into the hole by the drill bit during drilling, which could result in an uneven hole wall and affect the accuracy and quality of drilling, an arc-shaped cover is fixedly connected to the side of the rack near the rotating rod, and a steel wire rod is fixedly connected to the side of the arc-shaped cover away from the rack. During the rotation of the brush, the steel wire rod contacts the bristles of the brush, which can scrape away those hard-to-remove impurities trapped between the bristles, preventing the brush from being affected by the accumulation of impurities after repeated use, and ensuring that the brush can always maintain a good cleaning ability. The side of the rack away from the rotating rod is slidably connected to the side plate, and the bottom of the rack meshes with the top of the gear. Multiple brushes are provided, and the multiple brushes are evenly distributed on one side of the sponge tube.

[0007] Furthermore, the collection device includes a filter plate and a small sleeve. The filter plate blocks and adsorbs the drilling iron filings sucked in by the fan blades, preventing the iron filings from entering other components inside the equipment. This allows impurities to concentrate on the surface of the filter plate, facilitating subsequent cleaning and collection by the scraper. Air guide plates are fixedly connected to both sides of the bottom of the filter plate. The air guide plates guide the dispersed airflow into a concentrated airflow, enabling the fan blades to more effectively capture and accelerate the air, ensuring the equipment can clean more impurities in a shorter time. A ventilation plate is fixedly connected to the bottom of the air guide plate, and a circular sleeve is fixedly connected to the bottom of the ventilation plate. A motor is fixedly connected to the inner wall of the circular sleeve, and a cylinder is fixedly connected to the drive shaft of the motor. A sleeve block is fitted and fixedly connected to one side of the cylinder, and a fan blade is fixedly connected to one side of the sleeve block. The high-speed rotation of the fan blades generates suction, drawing the drilling iron filings towards the fan blades, allowing them to be blocked and adsorbed by the subsequent filter plate, thus collecting and cleaning drilling impurities and preventing iron filings from scattering. A compression spring is fixedly connected to the top of the inner wall of the small sleeve. A slanted cylinder is fixedly connected to the bottom of spring one. The slanted cylinder compresses spring one to prevent it from twisting or deforming under non-axial force. When the scraper moves along the inner wall of the slanted groove, the bottom surface of the slanted cylinder has the same inclination as the slanted surface, and the interaction between its own weight and spring one allows the scraper to better conform to the slanted surface and scrape away impurities. A compression spring two is sleeved and slidably connected to one side of the slanted cylinder. The scraper is fixedly connected to the bottom of the compression spring two. The scraper moves on the worktable surface and scrapes away impurities through the friction generated with the surface. Dust and other impurities are removed, and iron filings and other impurities adsorbed on the surface of the filter plate are scraped into the collection box to clean the filter plate, preventing it from becoming clogged and affecting airflow. The filter plate and the air guide plate are both set inside the rectangular groove and fixedly connected to the inner wall of the rectangular groove. The bottom of the circular sleeve is fixedly connected to the bottom of the inner wall of the rectangular groove. The bottom of the small sleeve is fixedly connected to the top of the base plate. The top of the second compression spring is fixedly connected to the bottom of the base plate. Multiple fan blades are provided, and the multiple fan blades are distributed on the side of the sleeve block.

[0008] The beneficial effects of this invention are as follows:

[0009] 1. This invention utilizes an electromagnetic chuck to generate a magnetic field through an internal coil, magnetizing the fuel pump and creating suction. This allows the fuel pump to be firmly adhered to the surface, ensuring its position remains stable during processing. A rubber strip on the inner side of the arc-shaped plate contacts and presses against the fuel pump; the rough surface of the rubber strip increases the contact area and friction, effectively preventing the fuel pump from sliding and ensuring it won't shift due to external forces during processing. The rough surface of the sponge tube, upon contact with the fuel pump surface, causes the rotating rod to rotate, carrying away oil and dirt from the pump surface. Utilizing its own adsorption and friction, it effectively cleans oily stains from the fuel pump surface. A scraper moves across the worktable surface, scraping away dust and other impurities through friction, and also scraping iron filings and other impurities adsorbed on the filter plate into the collection box, thus cleaning the filter plate and preventing clogging that could impede airflow.

[0010] 2. This invention, through the installation of a clamping device, uses an electromagnetic chuck with an internal coil to generate a magnetic field, magnetizing the fuel pump and generating suction force. This allows the fuel pump to be firmly adhered to the surface, ensuring that the fuel pump's position does not shift during processing. The rubber strip on the inner side of the arc-shaped plate contacts and presses against the fuel pump. The rough surface of the rubber strip increases the contact area and friction, effectively preventing the fuel pump from sliding and further enhancing the firmness of the fuel pump fixation. This ensures that the fuel pump will not shift due to external forces during processing. When the borer vibrates during drilling, the spring is compressed, converting the vibration energy into elastic potential energy for storage, thus acting as a buffer and protecting the fuel pump from damage that may be caused by excessive vibration. The circular groove restricts the electromagnetic chuck from swaying in all directions, preventing the drilling position from shifting due to the instability of the electromagnetic chuck and ensuring the accuracy of the drilling position. The arc-shaped hole on the base plate prevents the boring tool from contacting the base plate during drilling, avoiding tool damage or base plate wear caused by the boring tool colliding with the base plate, and extending the service life of the tool and base plate.

[0011] 3. This invention features a cleaning device with a rough sponge tube surface. When in contact with the fuel pump surface, friction causes the rotating rod to rotate, carrying away oil stains from the fuel pump surface. Utilizing its own adsorption and friction, it effectively cleans oily stains adhering to the fuel pump surface. As the brush rotates with the sponge tube, it directly contacts the fuel pump surface, reaching deep into crevices and uneven areas to effectively scrape away dust, rust, and other substances, further improving the cleaning effect. This prevents dust particles from being carried into the hole by the drill bit during drilling, which could result in an uneven hole wall and affect drilling accuracy and quality. During the brush's rotation, the steel wire rod contacts the brush bristles, scraping away hard-to-remove impurities trapped between the bristles, preventing the brush from accumulating impurities after repeated use and ensuring the brush maintains good cleaning ability.

[0012] 4. This invention, by setting up a collection device, has a scraper moving on the workbench surface. The friction generated with the surface scrapes away dust and other impurities, and also scrapes iron filings and other impurities adsorbed on the filter plate surface into the collection box, thus cleaning the filter plate and preventing clogging that could affect airflow. A fixed compression spring in an inclined cylinder prevents it from twisting or deforming under non-axial forces. When the scraper moves along the inner wall of the inclined groove, the bottom surface of the inclined cylinder has the same inclination as the inclined surface, and the interaction between its own weight and the spring allows the scraper to better conform to the inclined surface and remove impurities. The high-speed rotation of the fan blades generates suction, drawing the metal filings from the drilling towards the blades. These filings are then trapped and absorbed by the subsequent filter plate, effectively collecting and cleaning the drilling debris and preventing it from scattering. The air guide plate directs the dispersed airflow into a concentrated flow, allowing the fan blades to more effectively capture and accelerate the air, ensuring the equipment can clean more debris in a shorter time. The filter plate traps and absorbs the metal filings drawn in by the fan blades, preventing them from entering other internal components and concentrating the debris on its surface for easy collection and cleaning by the subsequent scraper.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0023] For the first embodiment, please refer to... Figures 1-4 This invention relates to a bore machining device for an electronically controlled fuel pump for motorcycles, comprising a workbench 1, a side plate 2 fixedly connected to the top of the workbench 1, a three-panel plate 3 fixedly connected to the top of the side plate 2, a bore machining tool 4 fixedly connected to the top of the inner wall of the three-panel plate 3, a clamping device 5 fixedly connected to one side of the side plate 2, a cleaning device 6 slidably connected to the side of the side plate 2 near the clamping device 5, an inclined groove 7 formed on the top of the workbench 1, a rectangular groove 8 formed on the inner wall of the inclined groove 7, a rectangular hole 9 formed on one side of the inner wall of the rectangular groove 8, an air outlet 10 formed on the side of the inner wall of the rectangular groove 8 below the rectangular hole 9, a collecting device 11 fixedly connected to the inner wall of the rectangular groove 8, and a collecting box 12 fixedly connected to one side of the workbench 1.

[0024] The clamping device 5 includes a motor 501. A T-shaped rod 502 is fixedly connected to the drive shaft of the motor 501. A gear 503 is sleeved and fixedly connected to one side of the T-shaped rod 502. A rack 504 meshes with one side of the gear 503. A limit plate 505 is fixedly connected to one end of the rack 504. A connecting rod 506 is fixedly connected to one side of the rack 504. A rectangular plate 507 is fixedly connected to the end of the connecting rod 506 away from the rack 504. An electric push rod 508 is fixedly connected to the side of the rectangular plate 507 away from the connecting rod 506. An arc-shaped plate 509 is fixedly connected to the drive shaft of the electric push rod 508. A rubber strip 510 is fixedly connected to the inner side of the arc-shaped plate 509. A base plate 5 is fixedly connected to the bottom of the rectangular plate 507 away from the connecting rod 506. 11. A circular groove 513 is provided at the center of the top of the base plate 511. Arc-shaped holes 512 are provided on both sides of the top of the base plate 511 located in the circular groove 513. A spring 514 is fixedly connected to the bottom of the inner wall of the circular groove 513. An electromagnetic chuck 515 is fixedly connected to the top of the spring 514. A circular hole 516 is provided at the top of the base plate 511. The side of the motor 501 is fixedly connected to one side of the side plate 2. One end of the T-shaped rod 502 passes through the side plate 2 and is rotatably connected to the side plate 2. The side of the rack 504 away from the connecting rod 506 is slidably connected to one side of the side plate 2. Multiple rubber strips 510 are provided, and the multiple rubber strips 510 are evenly distributed on the inner side of the arc plate 509. In use, the fuel pump is placed on the surface of the clamping device 5. 5 clamps the fuel pump inward, then moves the fuel pump towards the borer 4. Simultaneously, the cleaning device 6 moves in the opposite direction to the clamping device 5. As the clamping device 5 passes the cleaning device 6, the cleaning device 6 contacts the surface of the fuel pump and removes dust and oil. Some dust and dirt fall into the inclined groove 7. The movement of the clamping device 5 also moves the collecting device 11 fixedly connected to it. The collecting device 11 scrapes across the inclined groove 7, removing dust and dirt. When the clamping device 5 reaches below the borer 4, the borer 4 begins drilling the fuel pump. The clamping device 5 reduces vibration during drilling, and the collecting device 11 activates, sucking in the metal filings generated during drilling. After the borer 4 finishes its work, the clamping device 5 continues to move, driving the collecting device 11 to push various impurities into the collecting box 12. The fuel pump is placed on the base plate 511, with its bottom in contact with the surface of the electromagnetic chuck 515. The power to the electromagnetic chuck 515 is turned on, energizing the internal coil. The current passing through the coil generates a magnetic field, magnetizing the fuel pump and generating suction, tightly adhering the object to the surface of the electromagnetic chuck 515. After fixing, the drive shaft of the electric push rod 508 extends inward, driving the arc plate 509 to move until it clamps the fuel pump. At the same time, the rubber strip 510 on the inner side of the arc plate 509 contacts the fuel pump and presses against it. The rough surface of the rubber strip 510 increases the contact area with the fuel pump, increasing the friction.To prevent the fuel pump from slipping, motor 501 starts working, driving gear 503 to rotate. The teeth of gear 503 mesh with the teeth of rack 504. Through the interaction between the teeth, rack 504 is driven to begin linear motion, moving the fuel pump to the bottom of borer 4. When borer 4 begins drilling, it generates downward vibrations on the fuel pump. The spring 514 installed at the bottom of electromagnetic chuck 515 is compressed, converting the vibration energy into the elastic potential energy of spring 514 for storage, thus acting as a buffer. Circular groove 513 restricts the electromagnetic chuck 515 from swaying in all directions, preventing the drilling position from shifting. The base plate 511 has an arc-shaped hole 512 at the drilling position to prevent the boring tool from contacting the base plate 511 during drilling.

[0025] For the second embodiment, please refer to... Figures 1-8 This invention provides a bore processing device for an electronically controlled fuel pump in a motorcycle: a cleaning device 6 includes a rack 2 601, a rotating rod 602 rotatably connected to one side of the rack 2 601 via a rotating bolt, a hollow cylinder 603 sleeved and fixedly connected to one side of the rotating rod 602, a sponge tube 604 sleeved and fixedly connected to one side of the hollow cylinder 603, a brush 605 fixedly connected to one side of the sponge tube 604, an arc-shaped cover 606 fixedly connected to the side of the rack 2 601 near the rotating rod 602, a wire rod 607 fixedly connected to the side of the arc-shaped cover 606 away from the rack 2 601, a side of the rack 2 slidably connected to one side of the side plate 2, the bottom of the rack 2 601 meshing with the top of the gear 503, and multiple brushes 605 are provided, and the multiple brushes 605 are evenly distributed on one side of the sponge tube 604;

[0026] The collecting device 11 includes a filter plate 1101 and a small sleeve 1109. Air guide plates 1102 are fixedly connected to both sides of the bottom of the filter plate 1101. A ventilation plate 1103 is fixedly connected to the bottom of the air guide plate 1102. A circular sleeve 1104 is fixedly connected to the bottom of the ventilation plate 1103. A motor 1105 is fixedly connected to the inner wall of the circular sleeve 1104. A cylinder 1106 is fixedly connected to the drive shaft of the motor 1105. A sleeve block 1107 is fitted and fixedly connected to one side of the cylinder 1106. A fan blade 1108 is fixedly connected to one side of the sleeve block 1107. A compression spring 1110 is fixedly connected to the top of the inner wall of the small sleeve 1109. An inclined cylinder 1111 is fixedly connected to the bottom of the compression spring 1110. A compression spring 1112 is fitted and slidably connected to one side of column 1111. A scraper 1113 is fixedly connected to the bottom of compression spring 1112. Filter plate 1101 and air guide plate 1102 are both set inside rectangular groove 8 and fixedly connected to the inner wall of rectangular groove 8. The bottom of circular sleeve 1104 is fixedly connected to the bottom of the inner wall of rectangular groove 8. The bottom of small sleeve 1109 is fixedly connected to the top of base plate 511. The top of compression spring 1112 is fixedly connected to the bottom of base plate 511. Multiple fan blades 1108 are provided, and multiple fan blades 1108 are distributed on the side of sleeve block 1107. When in use, when motor 501 starts working, rack 601, which meshes with gear 503, simultaneously engages with rack 501. 4. The opposite linear motion drives the rotating rod 602 and the hollow cylinder 603 fixed to the surface of the rotating rod 602 to move. The sponge tube 604, which is sleeved and fixed to the surface of the hollow cylinder 603, moves accordingly. When the sponge tube 604 moves relative to the fuel pump, it comes into contact with it. The rough surface of the sponge tube 604 generates friction when it comes into contact with the surface of the fuel pump, causing the rotating rod 602 to rotate. The sponge tube 604 rotates with the rotating rod 602, cleaning the surface of the fuel pump and removing surface oil. When the sponge tube 604 rotates, the brush 605 fixed to the surface of the sponge tube 604 rotates and comes into contact with the surface of the fuel pump, cleaning and scraping off dust, rust, and other substances from the surface of the fuel pump. When the brush 605 rotates with the sponge tube 604, it passes over the upper wire rod 607. The wire rod 607 and the brush... The bristles of brush 605 contact and scrape away the hard-to-remove impurities trapped between the bristles. When the base plate 511 moves, it drives the compression spring 1110 fixed to the bottom of the base plate 511 to move. The scraper 1113 fixed to the bottom of the compression spring 1110 moves accordingly. When the scraper 1113 moves on the surface of the worktable 1, it generates friction. Due to the friction, the scraper 1113 is subjected to a force opposite to the direction of movement. The inclined cylinder 1111 fixes the compression spring 1110 to prevent the compression spring 1110 from twisting and deforming when subjected to non-axial forces, ensuring that the scraper 1113 moves smoothly on the surface of the worktable 1. At this time, the compression spring 1110 is in a compressed state due to the force generated by the surface of the worktable 1 on the scraper 1113.The scraper 1113 provides an upward supporting force to the inclined cylinder 1111, keeping the compression spring 1112 in its normal state. When the scraper 1113 moves to the inner wall of the inclined groove 7, the pressure direction on the scraper 1113 changes because the bottom of the inner wall of the inclined groove 7 is inclined. The compression spring 1112 extends downward along the inclined surface, causing the scraper 1113 to adhere to the inclined surface and scrape away dust and other impurities on the surface. The bottom surface of the inclined cylinder 1111 has the same inclination as the inclined surface. The compression spring 1110 extends downward due to the gravity of the inclined cylinder 1111. When it moves to the surface of the filter plate 1101, the axial force on the compression spring 1112 is evenly distributed, and the scraper 1113 returns to a horizontal state. When the borer 4 drills a hole in the fuel pump... The drive shaft of the motor 1105 rotates, causing the cylinder 1106 to rotate. The sleeve block 1107, fitted onto one side of the cylinder 1106, rotates accordingly. The rotation of the sleeve block 1107 drives the fan blade 1108 to rotate at high speed, generating suction. Air guide plates 1102 are provided on both sides of the fan blade 1108, guiding the dispersed airflow into a concentrated airflow directed towards the fan blade 1108. This allows the fan blade 1108 to more effectively capture and accelerate air, improving the equipment's suction efficiency. Iron filings generated during drilling are attracted to the fan blade 1108 by suction and are blocked and adsorbed onto the surface of the filter plate 1101. After drilling is completed, the motor 501 continues to operate, driving the scraper 1113 to move, scraping impurities from the surface of the filter plate 1101 into the collection box 12.

[0027] In operation, the fuel pump is placed on the surface of the clamping device 5, which clamps the fuel pump inward. The fuel pump is then moved towards the borer 4. Simultaneously, the cleaning device 6 moves in the opposite direction to the clamping device 5. As the clamping device 5 passes the cleaning device 6, the cleaning device 6 contacts the surface of the fuel pump and removes dust and oil. Some dust and dirt fall into the inclined groove 7. The movement of the clamping device 5 also moves the collecting device 11 fixedly connected to it. The collecting device 11 scrapes across the inclined groove 7, removing the dust and dirt. When the clamping device 5 reaches below the borer 4, the borer 4 begins drilling the fuel pump. The clamping device 5 slows down the drilling process during drilling. The vibration generated during drilling activates the collecting device 11, drawing the iron filings produced during drilling into its inner wall. After the borer 4 finishes its work, the clamping device 5 continues to move, pushing various impurities into the collecting box 12. The fuel pump is placed on the base plate 511, with its bottom in contact with the surface of the electromagnetic chuck 515. The electromagnetic chuck 515 is powered on, energizing its internal coil. The current passing through the coil generates a magnetic field, magnetizing the fuel pump and creating suction, firmly adhering the object to the surface of the electromagnetic chuck 515. After fixing, the drive shaft of the electric push rod 508 extends inward, moving the arc plate 509 until it clamps the fuel pump. Simultaneously, the rubber strip 510 on the inner side of the arc plate 509 contacts and presses against the fuel pump. 10. The rough surface increases the contact area with the fuel pump, increasing friction and preventing the fuel pump from slipping. Motor 501 starts working, driving gear 503 to rotate. The teeth of gear 503 mesh with the teeth of rack 504. Through the interaction between the teeth, rack 504 begins to move linearly, moving the fuel pump to the bottom of borer 4. When borer 4 begins drilling, it generates downward vibrations on the fuel pump. The spring 514 installed at the bottom of electromagnetic chuck 515 is compressed, converting the vibration energy into the elastic potential energy of spring 514 for storage, thus acting as a buffer. Circular groove 513 restricts the electromagnetic chuck 515 from swaying in all directions, preventing displacement of the drilling position. The base plate 511 has an arc-shaped hole 5 at the drilling position. 12. To prevent the boring tool from contacting the base plate 511 during drilling, when the motor 501 starts working, the rack 601, which meshes with the gear 503, simultaneously performs a linear motion opposite to that of the rack 504, driving the rotating rod 602 and the hollow cylinder 603 fixed to the surface of the rotating rod 602 to move. The sponge tube 604, which is sleeved and fixed to the surface of the hollow cylinder 603, moves accordingly. When the sponge tube 604 moves relative to the fuel pump, it comes into contact. The surface of the sponge tube 604 is rough, and friction is generated when it contacts the surface of the fuel pump, causing the rotating rod 602 to rotate. The sponge tube 604 rotates with the rotating rod 602, cleaning the surface of the fuel pump and removing surface oil. When the sponge tube 604 rotates, the brush 605 fixed to the surface of the sponge tube 604 rotates and comes into contact with the surface of the fuel pump.The brush 605, along with the sponge tube 604, rotates to clean and remove dust and rust from the surface of the fuel pump. As it passes the upper steel wire rod 607, the bristles of the brush 605 come into contact with the bristles, scraping away the stubborn impurities trapped between them. When the base plate 511 moves, it moves the compression spring 1110 fixed to the bottom of the base plate 511. The scraper 1113, fixed to the bottom of the compression spring 1110, moves accordingly. As the scraper 1113 moves on the surface of the worktable 1, it generates friction. Due to this friction, the scraper 1113 experiences a force opposite to the direction of movement, resulting in an oblique shape. The cylinder 1111 fixes the compression spring 1110 to prevent it from twisting when subjected to non-axial forces, ensuring that the scraper 1113 moves smoothly on the surface of the worktable 1. At this time, the compression spring 1110 is in a compressed state due to the force exerted on the scraper 1113 by the surface of the worktable 1. The scraper 1113 has an upward supporting force on the inclined cylinder 1111, keeping the compression spring 1112 in its normal state. When the scraper 1113 moves to the inner wall of the inclined groove 7, the direction of the pressure on the scraper 1113 changes because the bottom of the inner wall of the inclined groove 7 is inclined. Spring 1112 extends downwards along the inclined plane, causing scraper 1113 to adhere to the inclined plane and scrape away dust and other impurities on the surface. The bottom surface of the inclined cylinder 1111 has the same inclination as the inclined plane. Due to the gravity of the inclined cylinder 1111, spring 1110 extends downwards and moves to the surface of filter plate 1101. When spring 1112 moves to the surface of filter plate 1101, the axial force on spring 1112 is evenly distributed, and scraper 1113 returns to a horizontal state. When borer 4 drills a hole in the fuel pump, the drive shaft of motor 1105 rotates, causing cylinder 1106 to rotate. The sleeve 1107 fitted on one side of cylinder 1106 rotates accordingly. The rotation of the sleeve 1107 drives the fan blade 1108 to rotate at high speed, generating suction. Air guide plates 1102 are installed on both sides of the fan blade 1108 to guide the dispersed airflow into a concentrated airflow directed towards the fan blade 1108, enabling the fan blade 1108 to more effectively capture and accelerate air, improving the equipment's suction efficiency. Iron filings generated during drilling are drawn towards the fan blade 1108 by suction and are blocked and adsorbed onto the surface of the filter plate 1101. After drilling is completed, the motor 501 continues to operate, driving the scraper 1113 to move and scrape the impurities on the surface of the filter plate 1101 into the collection box 12.
