[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, an internal transmission oil spraying device includes a worktable, an oil spraying assembly 2, a rotating assembly 4, and a changing assembly 5. The worktable (not shown in the figure) is provided with a fixture 1 for positioning the workpiece. The oil spraying assembly 2 is located on the changing assembly 5 and can extend into the workpiece to spray oil onto the workpiece's transmission component 2. The rotating assembly 4 is located directly below the fixture 1 and is used to drive the transmission component 2 to rotate during oil spraying. The changing assembly 5 is located behind the fixture 1 and is mounted on the worktable. It is used to drive the oil spraying assembly 2 to move and position the oil spraying assembly 2 on the worktable to adapt to oil spraying of different types of workpieces.

[0025] Among them, such as Figure 1 , 3 As shown, the fuel injection assembly 2 includes a fuel injection support 21, a screw pump 22, a lifting seat 23, a propulsion cylinder 24, a propulsion seat 25, a shifting cylinder 26, a fuel injection valve 27, and a fuel injection pipe 28. The screw pump 22 is fixed on the fuel injection support 21 and connected to the fuel injection valve 27. The top of the fuel injection support 21 is also equipped with a pressure stabilizing system 29 connected to the screw pump 22. The pressure stabilizing system ensures stable and uniform fuel injection. The lifting seat 23 is located on the front side of the fuel injection support 21 and is connected to a linear moving assembly on the fuel injection support 21. The component is slidably connected to the oil injection support 21. In this embodiment, the linear movement component is a moving component consisting of a slide rail and a lead screw. The lifting seat 23 is provided with an inclined propulsion cylinder 24. The inclination direction of the propulsion cylinder 24 is the same as the direction of the oil injection inlet and outlet on the workpiece. The output end of the propulsion cylinder 24 is provided with a propulsion seat 25. The propulsion seat 25 is provided with a shifting cylinder 26 that is perpendicular to the propulsion cylinder 24. The output end of the shifting cylinder 26 is provided with an oil injection valve 27. The outlet end of the oil injection valve 27 is provided with an oil injection pipe 28. During oil spraying, the lifting seat 23 descends, the propulsion cylinder 24 is activated to push the oil spray pipe 28 into the workpiece's oil spray port, and then the oil cylinder pump 22 and the oil spray valve 27 are activated to spray oil onto the transmission component two. At the same time, the rotating assembly 4 is activated, driving the transmission component two to rotate while spraying oil. After completing one revolution of oil spraying, the shifting cylinder 26 is activated, driving the oil spray pipe 28 to move a distance along the axis of the transmission component two. The transmission component two rotates one more revolution, and the oil spray pipe sprays again. This allows the transmission component two to be sprayed at a certain height, covering the upper and lower ends or the entire transmission component two, avoiding incomplete spraying. In addition, it should be noted that the number of revolutions of the rotating assembly 4 can be set according to the actual situation. In this embodiment, the upper and lower parts each rotate one revolution.

[0026] In the above structure, such as Figure 3 As shown, the lifting seat 23 is also provided with an adjustment component 31 for adjusting the tilt angle of the propulsion cylinder 24, thereby adjusting the angle at which the oil injection pipe 28 is inserted into the workpiece.

[0027] In addition, such as Figure 3 As shown, the fuel injection pipe 28 is rotatably connected to the fuel injection valve 37 via a rotating head 32. The rotating head has a handle, and a detection sensor for detecting the rotation angle of the rotating head is located on its rear side to prevent errors. The fuel injection pipe 518 has a fuel injection direction. The fuel injection angle is adjusted by rotating the fuel injection pipe 518 via the handle 522, adapting to the fuel injection angles of different types of workpieces, offering good flexibility. Simultaneously, the detection sensor 523 detects the corresponding fuel injection angle of the workpiece to ensure accurate fuel injection direction.

[0028] Example 2

[0029] Based on the structure of Example 1, such as Figure 1-3As shown, the form-changing assembly 5 includes an oil injection base 51, a form-changing cylinder 52, slide rails, and a standard rod 53. The oil injection base 51 is fixed on the worktable, and the form-changing cylinder 52 is fixed above the oil injection base 51, with its output end connected to the oil injection support 21. Two slide rails are provided, arranged parallel to the form-changing cylinder. The bottom of the oil injection support 21 has a slider that slides along the slide rails. A standard rod 53 is provided between the two slide rails, and the standard rod 53 is fixed on the oil injection base 41, limiting the stroke of the form-changing cylinder 52. One end of the standard rod 53 abuts against the oil injection support 21, and the other end has a fault-prevention detection sensor 54. During form-changing, the standard rod 43 corresponding to the workpiece to be oiled is installed. The fault-prevention detection sensor 54 detects whether the type of the standard rod 53 corresponds to the workpiece to be oiled. Then, the form-changing cylinder 52 is activated, pushing the oil injection support 21 towards the standard rod 53. It stops when it abuts against the standard rod 53, thus accelerating the form-changing speed. The position of the oil spray support 21 can be adjusted by changing the position of the oil spray component 5, so as to adapt to oil spraying of different types of workpieces, which is flexible and has a wide range of applications.

[0030] Among them, such as Figure 1 , 2 As shown in Figure 4, the rotating assembly 4 includes a mounting box 41, a servo motor 42, a coupling, a connecting rod 43, a pneumatic valve ring 44, and a gripper cylinder 45. The servo motor 42 is fixed below the mounting box 41, and its output end is connected to one end of the connecting rod 43 through the coupling. The other end of the connecting rod 43 is connected to the gripper cylinder 45. The gripper cylinder 45 is fixed on the pneumatic valve ring 44, and its output end is provided with a gripper for holding the first transmission component.

[0031] In the above structure, such as Figure 1 , 2 As shown, the mounting box 41 is also adjustablely connected to the worktable via an adjusting component. The adjusting component includes an adjusting seat 46 and a slide rail. The adjusting seat 46 is fixedly connected to the worktable and has a slide rail on its front side. The mounting box 41 is provided with a slider that is slidably connected to the slide rail. The mounting box 41 also has multiple adjusting holes 411 on both sides along the length of the slide rail. The mounting box 41 is fixedly connected to the adjusting seat 46 via a knob plunger installed on the adjusting hole 411, which can accommodate different types of workpieces.

[0032] This invention features automatic oil spraying, which rotates the transmission component to be sprayed during the process and simultaneously drives the oil spray pipe to move axially along the transmission component, ensuring uniform spraying and preventing incomplete spraying, thus improving spraying efficiency and quality. Furthermore, this invention can adapt to oil spraying on different types of steering gears and other transmission components, offering good flexibility and a wide range of applications.
