[0022] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1As shown, this application proposes an engine valve body oil injection device, which includes a machine base 1, a loading module 2, an oil injection module 3, an unloading module 4, and a transfer module 5 mounted on the machine base 1. The loading module 2 is used for loading and conveying the valve body to be injected, the oil injection module 3 is used for spraying oil around the valve body, the unloading module 4 is used for stacking and unloading the oil-injected valve body, and the transfer module 5 is used for transferring and transporting the valve body between the modules.

[0024] like Figure 1-3 As shown, the oil injection module 3 includes an oil reservoir 31, which is configured as a cavity structure to store oil. A loading component 32 for housing the valve body is provided within the cavity structure. An oil injection component 33 is circumferentially arranged on the loading component 32. The oil injection component 33 is connected to the oil in the oil reservoir via an oil pipe (not shown) to spray the oil from the cavity structure onto the circumference of the valve body on the loading component 32. Excess oil can flow back within the cavity structure for reuse, reducing oil waste and lowering costs.

[0025] like Figure 1-3 As shown, the material carrier 32 includes a material carrier bracket 321. A positioning boss 322 is provided on the upper end surface of the material carrier bracket 321. The positioning boss 322 is adapted to the central through hole of the valve body and is configured as a circular boss. The valve body is placed on the upper end surface of the material carrier bracket 321, and the material through hole is sleeved on the positioning boss 322 to limit the horizontal displacement of the valve body and maintain the stability of the valve body during the oil injection process.

[0026] like Figure 1-3 As shown, the oil spraying component 33 includes a plurality of oil injectors 331 arranged around the circumference of the material carrier 32. The spraying ends of the oil injectors 331 face the material carrier 32 and are aligned with the valve body on the material carrier 32. The oil injectors 331 are connected to an external air source through an air pipe (not shown) and atomize the oil through the siphon principle. Preferably, the oil injectors 331 are evenly distributed at equal intervals around the circumference of the material carrier 32 to improve the uniformity of oil spraying. In this specific embodiment, the oil spraying component 33 includes two sets of oil injectors 331, which are located on opposite sides of the material carrier 32.

[0027] Among them, the injector that achieves atomized oil spraying through the siphon principle is the existing technology in this field, so its structure will not be described in detail here.

[0028] like Figure 1-3 As shown, the upper end of the oil storage tank 31 is provided with a discharge port 311 and a sealing member 34 for opening or closing the discharge port 311. When the discharge port 311 is in the open state, the valve body performs the feeding and discharging action; after the sealing member 34 closes the discharge port 311, the oil spraying member 33 performs the oil spraying action. Preferably, the discharge port 311 is located directly above the material carrier 32.

[0029] like Figure 1-3 As shown, in a further embodiment, the sealing member 34 includes a transverse cylinder 341 and a sealing plate 342. The transverse cylinder 341 drives the sealing plate 342 to move to open or close the discharge port 311. The area of ​​the sealing plate 342 is larger than the area of ​​the discharge port 311 to ensure that the sealing plate 342 can completely cover the discharge port 311 and close it.

[0030] like Figure 1-3 As shown, specifically, limit plates 343 are parallel to each other on opposite sides of the discharge port 311 along the first direction. The limit plates 343 extend horizontally along the second direction, which is perpendicular to the first direction. Each set of limit plates 343 has a sliding groove extending horizontally along the second direction on the side near the discharge port 311. The opposite sides of the sealing plate 342 are fitted into the sliding groove, allowing the sealing plate 342 to slide along the groove. Preferably, the sliding groove is formed between the limit plates 343 and the upper surface of the oil tank 31, causing the sealing plate 342 to slide back and forth against the upper surface of the oil tank 31, preventing oil and gas from overflowing from the gap between the sealing plate 342 and the oil tank 31.

[0031] like Figure 1-2 As shown, preferably, the bottom of the oil storage tank 31 is connected to an oil supply pipe 35 for supplying oil to the interior of the cavity structure. Furthermore, in one embodiment, the oil storage tank 31 may be equipped with an oil filtration and circulation system to recycle excess oil and reduce waste.

[0032] In a specific embodiment, the transfer module 5 can employ pneumatic grippers in conjunction with a robotic arm or a rapid transport mechanism. The pneumatic grippers are used to grasp the valve body to achieve precise positioning and efficient transfer of the valve body; their specific structure is not limited. Preferably, the robotic arm end can be equipped with two sets of pneumatic grippers: one set for loading the valve body to be injected, and the other set for unloading the completed valve body, effectively accelerating the work cycle and improving work efficiency.

[0033] like Figure 1-3 As shown, in this embodiment, the loading module 2 includes a transfer carrier 21 and a displacement drive module 22 that drives the transfer carrier 21 to move horizontally. The displacement drive module 22 drives the transfer carrier 21 to reciprocate between the loading end and the unloading end, with the unloading end located on one side of the oil spraying module. The transfer carrier 21 receives the valve body to be sprayed from the external processing machine tool at the loading end, and then drives the valve body to move to the unloading end, so that the transfer module 5 can unload and transfer the valve body into the oil spraying module 3 for the valve body spraying process. Specifically, the structure of the transfer carrier 21 is the same as that of the loading component 32.

[0034] like Figure 1As shown, in this embodiment, the feeding module 4 includes a material tray 41 and a material tray stacker 42. The transfer module 5 sequentially places the valve bodies that have completed oil spraying into the material tray 41. After the material tray 41 is full, the full-load material trays are sequentially stacked into the material tray stacker. The material tray stacker is a conventional technical means in this field and will not be described in detail here.

[0035] Working principle:

[0036] Feeding module: The transfer carrier 21 receives the valve body at the feeding end, and the displacement drive module 22 drives the transfer carrier 21 and the valve body to move to the unloading end;

[0037] Transfer module: The valve body is gripped by a pneumatic gripper and transferred to the loading component 32 of the oil injection module 3 by a robotic arm;

[0038] Oil injection module: The transverse cylinder 341 pushes the sealing plate 342 to close the discharge port 311 to prevent oil mist from overflowing; the oil injector 331 is connected to compressed air through the air pipe, and uses the siphon effect to atomize the oil and spray it onto the valve body surface; after the oil injection is completed, the sealing plate 342 opens.

[0039] Transfer module: The robotic arm grabs the valve body that has been sprayed with oil on the loading component 32 and transfers it to the material tray 41 of the unloading module;

[0040] Material feeding module: The material palletizer 42 is used to neatly stack the full material pallets.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
