[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0034] like Figure 1 and Figure 7 As shown, the present invention is a continuous conveying coating oil spraying device for automobile drive shaft, comprising an oil spray box 1 and a conveying chain 2. The left and right side walls of the oil spray box 1 are both provided with openings for conveying the drive shaft. The conveying chain 2 passes through the openings and is fixed in the oil spray box 1. The drive shaft is conveyed by the conveying chain 2.

[0035] A plurality of oil guide pipes 3 are provided in the fuel injection box 1, and the plurality of oil guide pipes 3 perform rotational motion. A plurality of nozzles 4 are rotatably installed on the oil guide pipes 3. A first oil delivery pipe 5 is connected between the nozzle 4 and the oil guide pipes 3. A movable rod 6 is provided on each oil guide pipe 3, and the movable rod 6 is rotatably connected to the plurality of nozzles 4 on the oil guide pipe 3, and the plurality of nozzles 4 are driven to swing up and down synchronously through the movable rod 6.

[0036] When the oil pump 1 is turned on the oil pump 2, the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 will be turned to the oil pumping station, and the oil pump 1 The oil is sprayed vertically toward the axis of the transmission shaft, so that the oil sprayed by the nozzle 4 is sprayed vertically on the transmission shaft. When the transmission shaft moves to the other side of the spray tank 1, the oil guide pipe 3 is rotated to a fixed angle. At this time, the nozzle 4 performs an inclined spraying operation again, and the directions of the two inclined sprayings of the nozzle 4 are opposite. The transmission shaft continues to rotate during the transportation inside the spray tank 1, so that the oil falls completely on the transmission shaft. Since the nozzle 4 performs two inclined spraying operations, it is convenient to spray oil from two directions into the blind area inside the transmission shaft, avoiding the situation where the nozzle 4 can only spray oil on one side of the blind area inside the transmission shaft when it is tilted in one direction, resulting in a more one-sided oil spraying operation. During the oil spraying process, the nozzle 4 swings up and down synchronously, so that the nozzle 4 performs an inclined oil spraying operation synchronously in the vertical direction, so that the oil is evenly attached to the inside and outside of the transmission shaft, thereby realizing a comprehensive oil spray coating operation on the transmission shaft, and improving the uniformity of the oil film, realizing comprehensive protection of the transmission shaft by the oil film, and improving the oil spraying effect.

[0037] like Figure 2 and Figure 7 As shown, as a preferred embodiment of the above, main shafts 7 are rotatably installed on both sides of the left and right sides of the spray tank 1, transmission chain plates 9 are provided on the upper and lower sides of the spray tank 1, and transmission rollers 8 are provided on the left and right sides of the transmission chain plates 9. The transmission rollers 8 are fixed on the main shaft 7, and a first mounting plate 10 is installed on the outer wall of the transmission chain plate 9. The first mounting plate 10 is rotatably connected to the oil guide pipe 3. A first motor 11 is installed on the top of the spray tank 1, and the output end of the first motor 11 is transmission-connected to a main shaft 7.

[0038] In this embodiment, the first motor 11 drives the main shaft 7, the transmission roller 8, the transmission chain plate 9 and the first mounting plate 10 to rotate synchronously, and the first mounting plate 10 drives the oil guide pipe 3 to rotate, thereby realizing the rotary motion of the oil guide pipe 3, making it convenient for the oil guide pipe 3 to spray oil to the transmission shaft in a continuous conveying state in the injection tank 1.

[0039] like Figure 3 、 Figure 4 and Figure 7 As shown, as a preferred embodiment of the above embodiment, an annular guide groove 12 is provided on the top of the inner wall of the fuel injection tank 1. The middle portion of the annular guide groove 12 on the side close to the conveying chain 2 is configured as a U-shaped portion 13. The middle portion of the annular guide groove 12 on the side away from the conveying chain 2 is configured as a reversing portion 14. One side of the reversing portion 14 is configured as an arc and a tapered mouth, and the other side of the reversing portion 14 is configured as a straight line in an inclined state.

[0040] A connecting plate 15 is installed on the top of the oil guide pipe 3. A sliding post 16 is installed on the outer end of the connecting plate 15. The top of the sliding post 16 slides into the annular guide groove 12. A torsion spring 17 is installed on the outer wall of the oil guide pipe 3. The outer end of the torsion spring 17 is connected to the first mounting plate 10.

[0041] The opening direction of the cone opening on the reversing portion 14 is opposite to the sliding direction of the sliding post 16 in the annular guide groove 12 .

[0042] When the oil pump 15 is in the working state, the oil pump 15 is in the working state, and the oil pump 15 is in the working state. When the oil pipe 3 is tilted to the other side, the U-shaped part 13 can achieve the purpose of reversing the oil pipe 3, and the torsion spring 17 is in an elastically deformed state. When the nozzle 4 is tilted twice, it always faces the direction of the transmission shaft. When the slide post 16 slides to the rear side of the annular guide groove 12 and enters the reversing part 14 through the tapered opening of the reversing part 14, due to the slide post 16 being in a moving state, the torsion spring 17 is in an elastically deformed state, and the opening of the reversing part 14 is tapered, thereby causing the torsion spring 17 to push the oil pipe 3 to rotate, and the oil pipe 3 drives the slide post 16 to swing through the connecting plate 15. The slide post 16 is subjected to the inertia force and elastic thrust and swings from one side of the oil pipe 3 to the other side of the oil pipe 3. The slide post 16 swings to the linear area on the reversing part 14. At this time, the slide post 16 is converted from the pulling movement state of the oil pipe 3 to the pushing movement state of the oil pipe 3. The oil pipe 3 pushes the slide post 16 to continue sliding in the annular guide groove 12, and the reversing part 14 can achieve the purpose of reversing the oil pipe 3.

[0043] In this embodiment, by setting one side of the reversing portion 14 to be tapered, sufficient space can be provided for the swinging of the sliding column 16 to avoid obstruction to the sliding column 16.

[0044] like Figure 5 and Figure 6 As shown, as a preferred embodiment of the above embodiment, it also includes a moving ring 18, which is located in the spray tank 1, and a plurality of first sliders 19 are slidingly set on the outer wall of the moving ring 18, and a first push-pull plate 20 is installed on the first slider 19. The first push-pull plate 20 is slidably installed on the first mounting plate 10 on the transmission chain plate 9 on the lower side of the main shaft 7, and a second push-pull plate 21 is installed on the top of the first push-pull plate 20 for tilting and rotation. The outer end of the second push-pull plate 21 is rotatably provided with an arc guide rail 22, and the arc guide rail 22 remains in a horizontal state. A second slider 23 is slidingly set on the arc guide rail 22, and the second slider 23 is fixedly connected to the bottom of the moving rod 6.

[0045] In this embodiment, when the oil guide pipe 3 performs a rotational motion, the oil guide pipe 3 drives the first slider 19 to slide on the movable ring 18. When the oil guide pipe 3 swings and performs a reversing operation, the oil guide pipe 3 drives the second slider 23 to slide on the arc guide rail 22 through the movable rod 6, pushing the movable ring 18 to move up and down. The movable ring 18 pushes the arc guide rail 22 to move up and down through the first slider 19, the first push-pull plate 20 and the second push-pull plate 21. The arc guide rail 22 pushes the movable rod 6 to move up and down through the second slider 23, so that the nozzle 4 is in an up and down swinging state in the vertical direction. The first push-pull plate 20 can slide on the first mounting plate 10. By setting the movable ring 18, it is convenient to keep multiple nozzles 4 on each oil guide pipe 3 in a synchronous up and down swinging motion state.

[0046] like Figure 1 As shown, as a preferred embodiment of the above, a plurality of slide rods 24 are installed at the bottom of the movable ring 18, and the bottom of the slide rod 24 passes through the spray tank 1 and is slidably connected. A movable platform 25 is provided under the spray tank 1, and the bottom of the slide rod 24 is fixed on the movable platform 25. A rotating shaft 26 is provided between the movable platform 25 and the spray tank 1, and a second mounting plate 27 is provided at both ends of the rotating shaft 26, and the rotating shaft 26 is rotatably connected to the second mounting plate 27.

[0047] In this embodiment, the second motor 31 drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the push-pull ring 29 to move eccentrically through the eccentric wheel 28. The push-pull ring 29 drives the mobile platform 25 to move up and down through the third push-pull plate 30. The mobile platform 25 drives the moving ring 18 to move up and down through the slide rod 24. At the same time, the slide rod 24 can guide and support the mobile platform 25.

[0048] like Figure 5 and Figure 8 As shown, as a preferred embodiment of the above, a fixed plate 32 is installed at the bottom of the inner wall of the fuel injection tank 1, and an arc-shaped groove 33 is formed in the fixed plate 32.
