[0090] The following further describes the present utility model with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0091] This embodiment discloses a lubricating oil coating device for the surface of an aluminum alloy casting, including an oil pot 1, a pot lid 2 is arranged at the top end of the oil pot 1, a sprayer nozzle pipe 3 is vertically penetrated through the inner side of the pot lid 2, and an auxiliary structure 4 is arranged inside the oil pot 1;

[0092] A converging structure 5 is arranged at the bottom end of the sprayer nozzle pipe 3.

[0093] Refer to Figures 1 to 9 , in one aspect of this embodiment, the auxiliary structure 4 includes a first oil filling notch 401, a second oil filling notch 402 and an oil groove 403. The first oil filling notch 401 is arranged at the upper end inside the oil pot 1, the other side of the first oil filling notch 401 is provided with the second oil filling notch 402, the bottom end of the second oil filling notch 402 is provided with the oil groove 403, the inner structure of the first oil filling notch 401 is cylindrical, and the lubricating oil liquid is injected into the interior of the oil pot 1 through the second oil filling notch 402. At this time, the liquid flows into the interior of the oil pot 1 along the oil groove 403. When the lubricating oil liquid reaches the lowest end of the inner notch of the first oil filling notch 401, the injection of the lubricating oil liquid is stopped.

[0094] Among them, the design of the auxiliary structure 4, through the combination of the first oil filling notch 401, the second oil filling notch 402 and the oil groove 403, makes the injection and control process of the lubricating oil more efficient and precise, bringing the following effects:

[0095] Precise control of the oil injection volume: The setting of the first oil filling notch 401 forms a clear indication of the highest liquid level of the oil in the oil pot 1. When the lubricating oil liquid reaches the lowest end of the inner notch of the first oil filling notch 401, the injection will automatically stop, preventing over-injection. This design ensures the appropriate liquid level of the oil in the oil pot 1 and avoids overflow and waste.

[0096] Convenient oil injection operation: The second oil filling notch 402 is directly connected to the oil groove 403, so that the lubricating oil can be smoothly injected into the interior of the oil pot 1 through the second oil filling notch 402. The design of the oil groove 403 enables the oil liquid to be guided into the interior of the oil pot 1, simplifies the oil injection process, and reduces the difficulty and time of manual operation.

[0097] Prevent oil leakage and spillage: The intelligent oil tank 403 and oil filling notch design ensure stable introduction of lubricating oil, making it less likely to leak or spill, protecting the cleanliness of the environment around the equipment, and reducing the cleaning workload.

[0098] Uniform oil distribution: The setting of the oil tank 403 enables the lubricating oil to be evenly distributed inside the oil pot 1, ensuring that the lubricating oil does not concentrate in a certain area, promoting uniform lubrication of the internal parts of the equipment, and reducing local wear and heat accumulation.

[0099] Reduce maintenance costs: Precise control of the oil filling volume and efficient oil filling process reduce the waste of excess lubricating oil and lower the consumption cost of lubricating oil. At the same time, the uniform and good lubrication state reduces the wear and failure frequency of the equipment, further reducing the maintenance and replacement costs.

[0100] Reduce the burden on operators: The simple structure of the oil filling notch design and the oil guiding path of the oil tank 403 make the oil filling process more intuitive and convenient, reducing the work burden and technical requirements of operators and improving work efficiency.

[0101] Improve lubrication effect: By precisely controlling the lubricating oil level and optimizing the oil distribution, the working state of the lubricated components is optimized, improving the stability and efficiency of equipment operation and extending the service life of the equipment.

[0102] Comprehensively improve equipment reliability: Preventing overfilling and uniform oil distribution effectively reduce heat accumulation and frictional losses during equipment operation, improving the overall reliability and working performance of the equipment. The design of the auxiliary structure 4, through the combination of the first oil filling notch 401, the second oil filling notch 402, and the oil tank 403, realizes the high efficiency and precision of the lubricating oil injection process, bringing optimization effects in terms of convenient operation, preventing spillage, reducing waste, optimizing lubrication effect, and improving equipment reliability.

[0103] Refer to Figures 1 to 9 , in one aspect of this embodiment, the converging structure 5 includes a drainage pipe 501, an oil collecting tray 502, and a suction cup 503. The bottom end of the spray nozzle pipe 3 is provided with a drainage pipe 501. The bottom end of the drainage pipe 501 is provided with an oil collecting tray 502. A suction cup 503 is provided at the middle of the inner side of the oil collecting tray 502. The oil collecting tray 502 and the suction cup 503 are fixedly connected. The oil collecting tray 502 and the suction cup 503 introduce the lubricating oil inside the oil pot 1 into the inside of the drainage pipe 501. Since the area of the upper part of the oil collecting tray 502 is larger than the area of the lower part of the oil collecting tray 502, the upper end inside the oil collecting tray 502 allows the lubricating oil liquid within the unit range to enter the inside of the suction cup 503. And since the upper area of the suction cup 503 is smaller than the lower area of the suction cup 503, the suction cup 503 can evenly suck the lubricating oil liquid into the inside of the drainage pipe 501.

[0104] Among them, the design of the oil concentrating structure 5 realizes the efficient aggregation and introduction of lubricating oil liquid through the combination of the drainage pipe 501, the oil collecting tray 502 and the suction cup 503. The drainage process is smoother and more uniform, and specifically brings the following effects:

[0105] Optimize oil liquid aggregation: The design of the oil collecting tray 502 makes its upper area larger than the lower area, which can effectively aggregate the lubricating oil liquid within a unit range and increase the efficiency of oil liquid aggregation. This design helps to quickly collect the oil liquid and guide it to the suction cup 503.

[0106] Uniformly introduce oil liquid: The design feature of the suction cup 503 is that its upper area is smaller than the lower area, which means that the suction cup 503 can gradually and uniformly suck in the lubricating oil liquid. This design ensures that the oil liquid can be evenly distributed before entering the drainage pipe 501, avoiding over - quantity or retention, and maintaining the consistency and smoothness of the introduction process.

[0107] Efficient drainage: The drainage pipe 501 creates a direct and efficient oil liquid introduction path by connecting the oil collecting tray 502 and the suction cup 503. This design enables the lubricating oil to quickly and smoothly enter the drainage pipe 501 from the oil collecting tray 502 through the suction cup 503, reducing the friction and resistance during the introduction process and improving the efficiency of the entire drainage process.

[0108] Prevent oil liquid leakage: Due to the fixed connection relationship between various components such as the oil collecting tray 502 and the suction cup 503, the sealing and stability of the entire structure are ensured. This avoids the possibility of lubricating oil leakage or overflow during the introduction process, ensuring the utilization efficiency and cleanliness of the lubricating oil.

[0109] Guarantee equipment lubrication: The efficient and uniform drainage structure ensures that the lubricating oil inside the oil pot 1 can be timely and appropriately delivered to the parts that need lubrication, maintaining a good lubrication state of the internal parts of the equipment, and reducing the risk of wear and failures caused by wear.

[0110] Reduce manual operation: The automatic drainage function of the oil concentrating structure 5 makes the lubricating oil delivery process more automated and simple, reducing the dependence on manual operation, improving work efficiency, and reducing labor costs and the risk of operation errors.

[0111] Prolong the service life of the equipment: The stable and continuous lubrication state reduces the friction loss between mechanical parts, prolongs the service life of the equipment and parts, and improves the stability and reliability of equipment operation.

[0112] Improve the overall system performance: Through efficient drainage and uniform lubrication, the running stability and efficiency of the whole system are improved, reducing maintenance and downtime, bringing continuous high-efficiency operation and stable production capacity. The flow-accumulating structure 5 realizes the efficient accumulation and uniform introduction of lubricating oil liquid through the reasonable design and configuration of the drainage pipe 501, the oil-accumulating pan 502 and the suction cup 503, bringing effects and advantages in many aspects such as efficient drainage, uniform lubrication, leakage prevention, reduction of manual operation and extension of equipment life.

[0113] In this solution, all electrical equipment is powered by an external power supply.

[0114] Working principle: When in use, the staff injects the lubricating oil liquid into the interior of the oil pot 1 through the second oil injection notch 402. At this time, the liquid flows into the interior of the oil pot 1 along the oil groove 403. When the lubricating oil liquid reaches the lowest end of the inner notch of the first oil injection notch 401, stop injecting the lubricating oil liquid, and then cover the spray nozzle tube 3 and the pot lid 2 on the top of the oil pot 1. At this time, the oil-accumulating pan 502 and the suction cup 503 introduce the lubricating oil inside the oil pot 1 into the interior of the drainage pipe 501. Since the area of the upper part of the oil-accumulating pan 502 is larger than the area of the lower part of the oil-accumulating pan 502, the upper end inside the oil-accumulating pan 502 allows the lubricating oil liquid within the unit range to enter the interior of the suction cup 503, and the upper area of the suction cup 503 is smaller than the lower area of the suction cup 503. Therefore, the suction cup 503 can evenly suck the lubricating oil liquid into the interior of the drainage pipe 501.

[0115] The above is only the preferred implementation mode of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
