Description

Technical Field

[0001] This invention relates to the field of fuel injector head processing, and more particularly to a fuel injector head processing apparatus for marine diesel engines. Background Technology

[0002] Currently, the matrix material of composite fuel injectors for marine diesel engines is H13, and the surface composite layer is a nickel-based alloy, produced using powder metallurgy. However, powder metallurgy suffers from a porous structure, with a maximum density of only 97%, resulting in unstable room-temperature mechanical properties, high-temperature mechanical properties, and high-temperature fatigue performance. Furthermore, the low sintering temperature (approximately 1200℃) of the nickel-based alloy powder metallurgy process leads to poor integration with the H13 matrix, resulting in weak bonding between the nickel-based alloy composite layer and the H13 matrix, and ultimately, inconsistent quality.

[0003] When using other equipment to print composite layers on the surface of fuel engine nozzles using laser cladding, the thickness of the composite layer is affected by the amount of powder output from the laser cladding head during the printing process. Existing laser cladding heads are directly connected to small holes inside through several powder output tubes, resulting in a small deviation in powder output. However, when it is necessary to adjust the thickness of the composite layer according to different specifications of marine oil engine fuel engine nozzles, it is necessary to replace the laser cladding head with a different specification to adjust the powder output, which brings inconvenience to the processing.

[0004] Therefore, it is necessary to provide a new fuel injector head processing device for marine diesel engines to solve the above-mentioned technical problems. Summary of the Invention

[0030] 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.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 2A fuel injector nozzle for a marine diesel engine includes an injector seat 1, a pressure adjusting screw 2, a housing 5, a locking cap 6, an injector body 7, a composite layer 8, a lower spring seat 10, a locking spring 11, an upper spring seat 12, and a needle valve rod 13. The housing 5 is fixedly connected to one side of the injector seat 1. An oil drain hole 3 is provided on the surface of the injector seat 1. An oil inlet pipe connector 4 is provided on the outer side of the injector seat 1. The pressure adjusting screw 2 is installed on one side of the injector seat 1. The injector seat 1 has internal sliding... A spring upper seat 12 is connected, and a spring lower seat 10 is slidably connected inside the outer shell 5. A locking spring 11 is provided between the spring lower seat 10 and the spring upper seat 12. A tightening cap 6 is installed at one end of the outer shell 5, and an injector body 7 is installed at the other end of the tightening cap 6. A needle valve rod 13 is slidably inserted inside the outer shell 5. One end of the needle valve rod 13 is fixedly connected to the spring lower seat 10, and the other end of the needle valve rod 13 passes through the tightening cap 6 and is slidably inserted into the injector body 7. A composite layer 8 is fixedly connected to the outside of the injector body 7.

[0033] It should be noted that: the fuel injector nozzle is used on marine diesel engines. The nozzle body 7 has multiple nozzle holes machined on its head. The high-pressure diesel fuel output by the fuel injection pump enters the high-pressure oil chamber of the housing 5 through the inlet pipe connector 4. When the oil pressure overcomes the preload force of the locking spring 11 and the friction between the needle valve rod 13 and the cap 6, the needle valve rod 13 rises and the high-pressure diesel fuel is sprayed out through the nozzle hole. When the fuel injection pump stops supplying fuel, the needle valve rod 13 closes the nozzle hole under the action of the locking spring 11. A nickel-based alloy composite layer 8 is printed on part of the nozzle body 7 by laser cladding. The composite layer 8 has a dense structure and is firmly bonded to the surface of the fuel injector nozzle, effectively solving the problems of loose structure and fusion between the composite layer 8 and the surface of the fuel injector nozzle caused by the original powder metallurgy process.

[0035] It should be noted that: a rotatable three-jaw chuck 21 is provided on one side of the support base 20. During the processing, the fuel nozzle is clamped and fixed at the center of the three-jaw chuck 21. The metal composite layer 8 is printed on the surface of the continuously rotating fuel nozzle by the laser cladding head 22. During printing, the powder output of the laser cladding head 22 can be adjusted by the adjustment mechanism 9, thereby controlling the thickness of the metal layer printed by laser cladding.

[0036] Please see Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11 The adjusting mechanism 9 includes a rotating rod 91, a driving gear 92, a rotating cylinder 93, a worm gear 94, a worm 95, a driven gear 97, an annular plate 98, a powder feeding pipe 99, a connecting pipe 910, and a movable ring 912. A worm 95 is rotatably connected between the equipment base 17 and the receiving base 24. The rotating rod 91 is slidably inserted inside the sliding cylinder 26. The driving gear 92 is fixedly connected to the bottom end of the rotating rod 91. An annular plate 98 is fixedly connected to the outside of the laser cladding head 22. A movable ring 912 is rotatably connected to the outside of the annular plate 98. A driven gear 97 is fixedly connected to the outside of the movable ring 912. The driving gear 92 and the driven gear 97 are meshed together. A rotating cylinder 93 is rotatably connected between the fixed bases 28, and the rotating cylinder 93 is slidably connected to the outside of the rotating rod 91.

The other end of the powder feeding pipe 99 is connected to the corresponding powder feeding hole 29. A number of guide holes 911 are opened on the surface of the movable ring 912.

[0037] It should be noted that: the worm gear 94 is driven to rotate by the rotating drum 93, which in turn drives the driven gear 97 to rotate, thereby causing the movable ring 912 to rotate. The number of connections between the guide hole 911 and the round hole 913 is adjusted to regulate the amount of powder output from the laser cladding head 22, thereby controlling the thickness of the metal layer printed during laser cladding.

[0038] Please see Figure 10 and Figure 11 The equipment base 17 is rotatably connected to a rotating shaft 38, and a drive gear 39 is fixedly connected to the outside of the rotating shaft 38. A knob 33 is provided on one side of the equipment base 17. One end of the rotating shaft 38 is fixedly connected to the knob 33. A pinion 40 is fixedly connected to the outside of one end of the worm gear 95. The drive gear 39 and the pinion 40 are meshed together.

[0039] It should be noted that the knob 33 can be connected to the laser power control system of the laser cladding head 22 so that when the knob 33 adjusts the laser power of the laser cladding head 22, the powder output can also be adjusted. By rotating the knob 33, the drive gear 39 on the outside of the rotating shaft 38 is driven to rotate, thereby causing the pinion 40 to drive the worm gear 95 to rotate.

[0040] Please see Figure 5 and Figure 10 A motor base 32 is fixedly connected to one side of the equipment base 17. A second motor 31 is installed inside the motor base 32. A slide rail 34 is symmetrically fixedly connected to one side of the equipment base 17. A movable seat 35 is symmetrically provided on one side of the equipment base 17.

[0041] It should be noted that: driven by the second motor 31, the threaded rod 36 rotates, thereby causing the two sides of the movable seat 35 to slide on the corresponding slide rail 34, so as to adjust the lifting and lowering of the laser cladding head 22 inside the sleeve 23;

[0042] Please see Figure 5 and Figure 10 A baffle plate 96 is fixedly connected to the bottom end of the rotating rod 91;

[0043] It should be noted that the baffle 96 can prevent the rotating rod 91 from separating from the rotating drum 93 during the sliding process;

[0044] Please see Figure 3 and Figure 4 A robotic arm 16 is mounted on the top of the processing table 14, and the output end of the robotic arm 16 is fixedly connected to the equipment base 17.

[0045] It should be noted that the position adjustment of the equipment base 17 is achieved through the robotic arm 16.

[0046] Please see Figure 3 and Figure 4 A dual-axis moving assembly 18 is installed on the top of the processing table 14, and the output end of the dual-axis moving assembly 18 is fixedly connected to the moving platform 19.

[0047] It should be noted that the moving platform 19 is adjusted by driving the dual-axis moving component 18;

[0048] Please see Figure 3 and Figure 4 A first motor 25 is installed on one side of the support base 20, and the output end of the first motor 25 is fixedly connected to the three-jaw chuck 21.

[0049] It should be noted that the rotation of the three-jaw chuck 21 is controlled by the first motor 25 so that the surface of the fuel injector head being held can be laser coated.

[0050] Please see Figure 3 and Figure 4 The bottom four corners of the processing table 14 are all fixedly connected with support legs 15;

[0051] It should be noted that the support feet 15 support the four bottom corners of the processing table 14, which facilitates the adjustment of the flatness of the processing table 14.

[0052] The working principle of the fuel injector head processing device for marine diesel engines provided by this invention is as follows: A rotatable three-jaw chuck 21 is provided on one side of the support base 20. During the processing, the fuel injector head is clamped and fixed at the center of the three-jaw chuck 21. A metal composite layer 8 is printed on the surface of the continuously rotating fuel injector head by the laser cladding head 22. During printing, the threaded rod 36 is rotated by the drive of the second motor 31, thereby driving the two sides of the movable base 35 to slide on the corresponding slide rails 34, so as to adjust the height of the laser cladding head 22 in the sleeve 23. When the appropriate height is adjusted, the rotation of the three-jaw chuck 21 is controlled by the first motor 25 so that the clamped fuel injector head can rotate continuously. The metal powder conveyed by the connecting pipe 910 enters the powder feeding pipe 99 through the round hole 913 and the guide hole 911, and then passes through the laser cladding head 22. The powder feeding hole 29 sprays onto the surface of the fuel injector nozzle. The laser melts the metal powder, and as the fuel injector nozzle rotates and moves, a composite layer 8 is printed on the fuel injector nozzle. When it is necessary to adjust the powder output, the knob 33 is turned. The knob 33 can be connected to the laser power control system of the laser cladding head 22 so that when the laser power of the laser cladding head 22 is adjusted by the knob 33, the powder output can also be adjusted. By rotating the knob 33, the drive gear 39 on the outside of the rotating shaft 38 is driven to rotate, thereby causing the pinion 40 to drive the worm 95 to rotate. The worm wheel 94 is driven to rotate through the rotating cylinder 93, which further causes the drive gear 92 to drive the driven gear 97 to rotate, thereby causing the movable ring 912 to rotate. The powder output of the laser cladding head 22 is adjusted by adjusting the number of connections between the guide hole 911 and the round hole 913, thereby controlling the thickness of the metal layer printed during laser cladding.

[0053] There are eighteen guide holes 911, which are distributed at equal intervals in the order of one, two, and three. There are nine round holes 913. The diameter of the guide holes 911 is the same as the inner diameter of the powder feeding pipe 99 and the connecting pipe 910. The distance between the center points of adjacent guide holes 911 is one-quarter or three-quarters of the distance between the center points of two adjacent round holes 913. Thus, when the movable ring 912 rotates ten degrees or more around the center point of the sleeve 23, the amount of communication between the guide holes 911 and the round holes 913 can be switched between nine, six, three, and zero, thereby controlling the amount of powder output.

[0054] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
