[0002] After engine connecting rods are processed and assembled into finished products, they need to be cleaned and oiled before being packaged. This cleaning and oiling process typically involves a reduction motor and chain drive assembly driving the drive chain. A hanger is then attached to the chain, and the finished connecting rods are manually placed on the hanger in the loading area. The connecting rods first enter an ultrasonic cleaning area for cleaning, and then enter the oiling process. Specifically, the oiling process involves the drive chain lowering the connecting rods into an anti-rust oil tank positioned directly below for immersion oiling. However, this process can be challenging: a significant amount of residual anti-rust oil remains on the connecting rod surface, making it difficult to color-code the sides of the connecting rods during unpacking by the OEM. This also results in high anti-rust oil consumption and high costs. Utility Model Content

DETAILED DESCRIPTION

[0021] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0022] Example

[0023] An engine connecting rod oiling device, such as Figure 1-4 The apparatus shown in the figure comprises a frame 1, a drive chain 2 that circulates through the upper portion of the frame 1, and an oil storage tank 3. A fuel injection pipe 7 is fixedly mounted on the inner wall of the frame 1. The fuel injection pipe 7 consists of a U-shaped portion and an inclined portion connected to the upper portions of the U-shaped portion on both sides. Several fuel injection pipes 7 are connected by connecting pipes 19. A circulating pump 4 is mounted on the outlet pipe of the oil storage tank 3, and the circulating pump 4 is connected to the connecting pipe 19 via an oil inlet pipe 5. Several atomizing nozzles 8 are mounted on the inner side of the fuel injection pipe 7. Also fixedly mounted on the inner wall of the frame 1 are several air injection pipes 11. These air injection pipes 11 have the same shape as the air injection pipes 7. Air nozzles 6 are mounted on the inner walls of each air injection pipe 11. Each air injection pipe 11 is connected to the outlet pipe of a high-pressure air pump 10 via a pipe. The reduction motor used to drive the drive chain and other components of the chain drive assembly are not shown and represent prior art.

[0024] In the above-mentioned engine connecting rod oiling equipment, the transmission chain 2 drives the hanger and parts to gradually move. After cleaning, they enter the oil spraying area in the frame 1. The circulating pump 4 draws the rust-proof oil in the oil storage tank 3 through the oil inlet pipe 5 to the connecting pipe 19, and then enters several oil spray pipes 7. Finally, the rust-proof oil is sprayed and atomized through the atomizing nozzle 8 and sprayed onto the surface of the parts. The parts continue to move forward and enter the oil blowing area. Using the high-pressure air pump 10 as the air source, the high-pressure gas enters the air jet pipe 11 and is finally ejected from the air jet nozzle 6. The ejected gas blows towards the parts, forming an air knife, blowing off the excess rust-proof oil on the surface of the parts, making the oil film on the surface of the parts more uniform, which can effectively reduce the consumption of rust-proof oil and save production costs. The oil film on the surface of the parts is evenly adhered, without leaking or dripping oil.

[0025] Specifically, the air injection pipe 11 and the oil injection pipe 7 are both fixedly mounted on the inner wall of the frame 1 through the fixing frame 9 .

[0026] Specifically, the system also includes an oil mist collector 13; the air inlet of the oil mist collector 13 is connected to a mist suction pipe 12; the other end of the mist suction pipe 12 extends to the top of the inner cavity of the frame 1. In this embodiment, the oil mist collector 13 is an electrostatic oil mist collector. The mist suction pipe 12 has three connections to the inner cavity of the frame 1, located at both ends and in the middle. The oil mist collector 13 draws the oil mist floating in the inner cavity of the frame 1 into the oil mist collector 13, where it is filtered, accumulated, and collected. After purification, the clean air is directly discharged into the workshop, and the collected anti-rust oil flows into its oil sump.

[0027] Specifically, in order to facilitate the recovery of the anti-rust oil collected by the oil mist recoverer 13 , the oil collecting tank inside the oil mist recoverer 13 is connected to the oil storage tank 3 through the oil collecting pipe 14 .

[0028] Specifically, a one-way valve 20 is installed on the oil collecting pipe 14 .

[0029] Specifically, in order to collect the anti-rust oil, an oil storage tank 17 is placed at the bottom of the inner cavity of the frame 1.

[0030] Specifically, in order to more conveniently recycle the anti-rust oil collected in the oil storage tank 17 , the oil storage tank 17 is connected to the oil storage tank 3 through a circulation pipe, and a pneumatic diaphragm pump 15 and a one-way valve 20 are installed on the circulation pipe.

[0031] Specifically, a filter 16 is installed on the circulation pipe. The filter 16 is used to filter impurities such as dust and flying chips in the rust-proof oil.

[0032] Specifically, the inner cavity of the oil storage tank 3 is equipped with an insulation layer and a liquid level sensor. When the temperature is low, the rust-proof oil needs to be heated to increase its fluidity. The insulation layer provides the oil storage tank with a heat-insulating function. The liquid level sensor monitors the liquid level within the oil storage tank and, when the liquid level drops to a certain value, promptly replenishes the oil storage tank with rust-proof oil.

[0033] The working principle of this utility model:

[0034] During operation, the transmission chain 2 drives the hanger and parts to gradually move. After cleaning, they enter the oil spraying area in the frame 1. The circulating pump 4 draws the anti-rust oil in the oil storage tank 3 through the oil inlet pipe 5 to the connecting pipe 19, and then enters several oil spray pipes 7. Finally, the anti-rust oil is sprayed and atomized through the atomizing nozzle 8 and sprayed onto the surface of the part. The part continues to move forward and enters the oil blowing area. Using the high-pressure air pump 10 as the air source, the high-pressure gas enters the air jet pipe 11 and is finally ejected from the air jet nozzle 6. The ejected gas blows towards the part, forming an air knife, blowing off the excess anti-rust oil on the part surface, making the oil film on the part surface more uniform, which can effectively reduce the consumption of anti-rust oil and save production costs. The oil film on the part surface is evenly adhered, without leaking or dripping oil.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
