Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] Example:

[0025] A fuel nozzle sealing cone surface polishing and grinding device includes a base plate 1. A guide rail 2, a rotating frame 3 and a first motor 4 are arranged sequentially on the upper side of the base plate 1 along the left and right directions. A first slider 5 is slidably arranged on the upper side of the guide rail 2. A fixing seat 6 for fixing a fuel nozzle 66 is arranged on the upper side of the first slider 5. A first rotating hole 7 is provided on the rotating frame 3, which passes through the left and right sides. A grinding rod 8 is rotatably arranged in the first rotating hole 7. A grinding groove 9 for polishing the sealing surface of the fuel nozzle 66 is recessed on the left end of the grinding rod 8. The output shaft of the first motor 4 is coaxially connected to the right end of the grinding rod 8 through a coupling 10. By fixing the fuel nozzle 66 to the fixed base 6, the first slider 5 drives the fuel nozzle 66 to move linearly along the guide rail 2, so that the sealing cone surface of the fuel nozzle 66 enters the grinding groove 9 of the grinding rod 8. Then, the first motor 4 drives the grinding groove 9 to rotate at high speed, thereby polishing and grinding the sealing cone surface of the fuel nozzle 66. After grinding is completed, the first slider 5 drives the fuel nozzle 66 to separate from the grinding rod 8, and then the fuel nozzle 66 can be removed.

[0026] A first electric telescopic rod 11 is provided on the upper side of the base plate 1. The output shaft end of the first electric telescopic rod 11 is positioned to the right, and a first push block 12 is installed at the end. A pressure hole 13 is provided on the right side of the first push block 12. A pressure sensor 14 is provided at the bottom of the pressure hole 13. A second push block 15 is slidably disposed in the pressure hole 13. The left end of the second push block 15 abuts against the pressure sensor 14 through a first spring 16, and the right end is positioned outside the pressure hole 13 at the right end of the first push block 12 and is connected to the left side of the first slider 5. When the fuel nozzle 66 needs polishing, the first electric telescopic rod 11 is extended to move the first slider 5 toward the polishing rod 8. Once the fuel nozzle 66 is in contact with the polishing groove 9, the first slider 5 cannot move further. At this point, the first push block 12 and the second push block 15 move closer together to compress the first spring 16. The first spring 16 then applies pressure to the pressure sensor 14. When the pressure reaches a certain value, the movement of the first electric telescopic rod 11 is stopped to maintain a certain pressure contact between the fuel nozzle 66 and the polishing groove 9. This application uses the pressure sensor 14 to monitor the contact pressure between the fuel nozzle 66 and the polishing groove 9 at any time, thus improving the polishing effect with appropriate pressure. It also prevents excessive pressure from causing other damage to the fuel nozzle 66 during polishing.

[0027] A top frame 18 is mounted on the top of the base plate 1 via a support frame 17. A second electric telescopic rod 19 is vertically arranged on the lower side of the top frame 18. The lower end of the second electric telescopic rod 19 is connected to a processing block 20. A drive cavity 21 is provided inside the processing block 20. A drive rod 22 is horizontally arranged in the left-right direction inside the drive cavity 21. A first gear 23 is sleeved on the outer wall of the drive rod 22. A second motor 24 is mounted on the upper side of the processing block 20. A second gear 25 is mounted on the output shaft of the second motor 24. A connecting hole 26 is provided on the upper side of the processing block 20 at the position corresponding to the first gear 23, which passes through both sides. The second gear 25 passes through the connecting hole 26 and enters the drive cavity 21 to mesh with the first gear 23. A first processing groove 27 is provided on the left side of the processing block 20. The bottom of the first processing groove 27 is connected to the drive cavity 21 through a second rotating hole 28. An application block 29 is rotatably arranged inside the first processing groove 27. The left end of the drive rod 22 is connected to the application block 29. To improve the polishing effect, polishing agent or abrasive is added to the polishing area during the polishing process. This not only improves the polishing effect, giving the conical surface of the fuel nozzle 66 a mirror finish, but also reduces the wear of the grinding groove 9. After the fuel nozzle 66 is installed, the processing block 20 is lowered by the second electric telescopic rod 19, aligning the processing block 20 in the first processing groove 27 with the fuel nozzle 66. Then, the first electric telescopic rod 11 is extended to bring the conical surface of the fuel nozzle 66 into contact with the application block 29. The pressure value on the pressure sensor 14 determines whether the contact with the application block 29 is achieved. After contact, the first electric telescopic rod 11 stops extending, and the second motor 24 drives the drive rod 22 to rotate, thereby rotating the application block 29 to apply polishing agent or abrasive to the grinding surface of the fuel nozzle 66. This method replaces manual application, resulting in more even application and easier operation. After the coating is applied, the fuel nozzle 66 is moved a short distance to the left by the first electric telescopic rod 11, and then the second electric telescopic rod 19 moves the processing block 20 upward. Then the first electric telescopic rod 11 extends again, causing the fuel nozzle 66 to come into contact with the grinding groove 9 for polishing.

[0028] A coating groove 30 is provided on the left side of the coating block 29. A flexible coating layer 31 is provided on both the bottom and walls of the groove 30. A connecting block 32 is rotatably mounted inside the first rotating hole 7. A connecting hole 33 is provided on the left end of the connecting block 32. A first connecting rod 34 is provided on the right end of the coating block 29. The first connecting rod 34 is magnetically connected to the connecting hole 33. The right end of the connecting block 32 is coaxially connected to the left end of the drive rod 22. Both the first connecting rod 34 and the connecting hole 33 have polygonal cross-sections. The flexible coating layer 31 facilitates the adhesion of polishing agent and prevents damage to the surface of the fuel nozzle 66 during the coating process. The flexible coating layer 31 can be made of sponge or flexible bristles. Furthermore, the magnetic connection between the connecting block 32 and the connecting hole 33 allows for quick disassembly of the coating block 29, enabling replacement of the coating block 29 when the flexible coating layer 31 becomes damaged after prolonged use.

[0029] The lower end of the second electric telescopic rod 19 is connected to a mounting plate 35. A sliding groove 36 is provided on the lower side of the mounting plate 35 along the left-right direction. A second slider 37 is slidably connected within the sliding groove 36. The right side of the second slider 37 is connected to the right wall of the sliding groove 36 via a second spring 38. A second connecting rod 39 is provided on the lower side of the second slider 37. The lower end of the second connecting rod 39 is connected to the upper side of the processing block 20. A second processing groove 40 is provided on the right side of the processing block 20. The bottom of the second processing groove 40 is connected to the first... The third rotating hole 41 is connected to the drive cavity 21. The right end of the drive rod 22 passes through the third rotating hole 41 and is placed in the second processing groove 40. The right end of the drive rod 22 is coaxially connected to a cleaning rod 42. A cleaning brush 43 is provided on the outer wall of the right end of the cleaning rod 42. A nozzle 44 is provided at the bottom of the second processing groove 40. A first pump body 45 is provided on the upper side of the mounting plate 35. The outlet of the first pump body 45 is connected to the nozzle 44 through a first hose 46. The inlet of the first pump body 45 is connected to a cleaning agent through a second hose. Before grinding, in addition to applying polishing agent to the surface of the fuel nozzle 66, the grinding groove 9 also needs to be cleaned to remove the stains left by the previous grinding, thereby improving the polishing effect. By setting the mounting plate 35, this application can complete the cleaning of the grinding groove 9 while applying polishing agent to the fuel nozzle 66, improving the efficiency of the entire polishing process. Specifically, the processing block 20 is first positioned to the right of the fuel nozzle 66 via the second electric telescopic rod 19. Then, the first electric telescopic rod 11 extends, causing the first slider 5 and the fuel nozzle 66 to move to the right. When the fuel nozzle 66 presses against the coating groove 30, the extension of the first electric telescopic rod 11 pushes the processing block 20 to continue moving, and causes the second slider 37 to compress the second spring 38. When the cleaning rod 42 enters the grinding groove and its right end presses against the bottom of the grinding groove, the processing block 20 cannot move. The pressure value of the pressure sensor 14 will increase with the large pressure of the first spring 16. The compression generates a large pressure value. When the pressure value reaches a preset threshold, the first electric telescopic rod 11 stops extending and shortens by 2-4mm to prevent the right end of the cleaning rod 42 from pressing too tightly against the bottom of the grinding groove, and to prevent the fuel nozzle 66 from pressing too tightly against the flexible coating layer 31. Then, the second motor 24 drives the drive shaft to rotate, which in turn drives the coating block 29 and the cleaning rod 42 to rotate. At the same time, the first pump body 45 sprays cleaning agent into the grinding groove 9 through the nozzle 44. The cleaning agent, together with the rotating cleaning brush 43, can wash away the grinding residue in the grinding groove 9. The type of cleaning agent is selected according to the type of abrasive. If the abrasive is water-based, water or a water-based cleaning agent can be used as the cleaning agent. If the abrasive is oil-based, cleaning oil or an oil-based cleaning agent can be used for rinsing.During rinsing, the second treatment tank 40 covers the opening of the grinding groove 9, preventing dirt generated during cleaning from splashing and hitting the tank wall before dripping from the opening. After cleaning, the first electric telescopic rod 11 shortens, and the treatment block 20 returns to its original position with the help of the second spring 38. After returning to its original position, it moves upward via the second electric telescopic rod 19.

[0030] A horizontal bar 47 is provided on the side of the fixed section of the second electric telescopic rod 19. A vertical bar 48 is provided on the lower side of the horizontal bar 47. A third electric telescopic rod 49 is horizontally installed at the lower end of the vertical bar 48. The telescopic end of the third electric telescopic rod 49 is set towards the mounting plate 35, and a top rod 50 is provided at the end. A discharge short pipe 51 is installed on the side of the top rod 50. A material tank 52 and a second pump body 53 are installed on the upper side of the third electric telescopic rod 49. The outlet of the second pump body 53 is connected to the discharge short pipe 51 through a third hose 54, and the inlet is connected to the material tank 52 through a fourth hose 55. Transparent baffles 56 are provided on both the front and rear sides of the processing block 20. By setting up a second pump body 53 and a discharge short pipe 51, after the processing block 20 moves upward, the third electric telescopic rod 49 extends to drive the top rod 50 and the discharge short pipe 51 into the coating tank 30. Then, the second pump body 53 pumps the polishing agent in the material tank 52 to the tank wall of the coating tank 30, making it easier to apply to the surface of the fuel nozzle 66 during the next polishing. Furthermore, the continued extension of the third electric telescopic rod 49 can push the processing block 20 to continue moving to the right, so that the transparent baffle 56 can block both sides of the grinding groove 9, preventing the polishing agent from splashing out during the high-speed rotation of the polishing process.

[0031] The mounting base 6 includes a base rod 57 and an insert rod 58. The lower end of the base rod 57 is connected to the upper side of the first slider 5, and the upper end is provided with an insertion hole 59. An electromagnet 60 is provided at the bottom of the insertion hole 59. The lower end of the insert rod 58 is provided with an adsorption block 61 that is magnetically connected to the electromagnet 60. The upper end of the insert rod 58 is provided with a mounting hole 62. Threaded holes for fixing the fuel nozzle 66 are provided around the mounting hole 62. The cross-section of both the insert rod 58 and the insertion hole 59 is polygonal. Before polishing, the main body of the fuel nozzle 66 is inserted into the mounting hole 62 of the insert rod 58, aligning the two mounting holes 62 on the fuel nozzle 66 with the threaded hole, and then secured with bolts. After securing, the insert rod 58 is inserted into the insertion hole 59 of the bottom rod 57, and the insert rod 58 is fixed in the insertion hole 59 by means of an electromagnet 60, preventing it from moving. The polygonal cross-section of the insert rod 58 and the insertion hole 59 prevents the insert rod 58 from rotating within the insertion hole 59, ensuring the installed fuel nozzle 66 is aligned with the grinding groove 9. Since the fuel nozzle 66 has two nozzles 44, requiring polishing twice, after polishing one nozzle 44, the electromagnet 60 is de-energized, and the insert rod 58 is removed and reinserted at a different angle. For example, if the included angle between the two nozzles 44 is 60 degrees, and the cross-section of the insertion holes 59 of the insert rod 58 is a regular hexagon, changing one side will align the two nozzles 44 with the grinding groove 9.

[0032] A flexible wastewater tank 63 is provided between the base plate 1 and the first slider 5 and the rotating frame 3. A support plate 64 is vertically arranged on the right side of the first slider 5. The left side of the flexible wastewater tank 63 is connected to the support plate 64, and the right side is connected to the rotating frame 3. A drain pipe 65 is connected to the bottom of the flexible wastewater tank 63. By providing the flexible wastewater tank 63, dirt generated during the cleaning process and dirt generated during the polishing process can be discharged through the drain pipe 65. The support plate 64 allows the flexible wastewater tank 63 to deform as the first slider 5 moves, adapting to the distance between the first slider 5 and the rotating frame 3.

[0033] A control module 67 is installed on the upper side of the base plate 1. The control module 67 includes at least a PLC control unit, which can control all the motors and electric telescopic rods of the equipment. It can achieve automated polishing and grinding through programmed control, and precisely control the movement trajectory of all components and the duration of each step.
