Technical Field

[0001] The invention relates to the technical field of engine cylinder heads, in particular to a device and a method for oiling bolts of an engine cylinder head. Background Art

[0002] Most engines in the prior art use a gray cast iron cylinder head with one cylinder and one head, and each cylinder head is fixed to the engine crankcase by four cylinder head bolts. Before the cylinder head bolts are installed, it is necessary to apply engine oil to the bolt threaded part.

[0003] The existing method of oiling cylinder head bolts is to manually oil the cylinder head bolts one by one with a brush, and then manually place the cylinder head bolts one by one on a plastic pad. The same steps need to be repeated dozens of times to complete the oiling of the cylinder head bolts for an engine. This oiling method is time-consuming and labor-intensive, has the problems of large oiling amount, oil leakage risk, low oiling efficiency, and high labor intensity for operators. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a device and method for oiling engine cylinder head bolts, which uses a pneumatic spray gun and a mobile trolley to spray a small amount of engine oil evenly onto the threaded parts of the cylinder head bolts. The oiling of the cylinder head bolts for an engine can be completed with only one operation.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: A device for oiling engine cylinder head bolts comprises a pneumatic spray gun for spraying engine oil and a mobile trolley for placing cylinder head bolts; a filter is arranged at the upper end of the mobile trolley, an oil receiving pan arranged parallel to the filter is arranged at the lower end of the mobile trolley, and cylinder head bolts are placed on the upper surface of the cylinder head bolts.

[0006] A further improvement of the technical solution of the present invention is that the mobile vehicle also includes a frame of a frame structure and wheels arranged at the bottom end of the frame.

[0007] A further improvement of the technical solution of the present invention is that four wheels are provided.

[0008] A further improvement of the technical solution of the present invention is that a handle is provided on an upper end of one side of the mobile vehicle.

[0009] A method for lubricating an engine cylinder head bolt, comprising the following steps: Step 1, prepare the pneumatic spray gun filled with engine oil and adjust the injection parameters; Step 2, move the mobile cart to a convenient position for oiling; Step 3, place all cylinder head bolts that need to be oiled for one engine on the filter screen of the mobile cart and arrange them evenly; Step 4: Use a pneumatic spray gun to evenly spray a small amount of engine oil onto the threaded surface of the cylinder head bolts. During the oil spraying process, excess engine oil flows through the filter into the oil receiving pan; Step 5: Recycle the engine oil in the oil pan.

[0010] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is: 1. In the present invention, the cylinder head bolts are evenly placed on the filter screen of the oiling device, and a small amount of engine oil is evenly sprayed onto the threaded surface of the cylinder head bolts through a pneumatic spray gun. The oiling of the cylinder head bolts for one engine can be completed in one operation, which can greatly improve efficiency, reduce labor intensity, and eliminate the hidden danger of engine oil leakage.

[0011] 2. The cylinder head bolt oiling method of the present invention adopts a pneumatic spray gun to spray oil, which can not only spray oil on the cylinder head bolts of an engine at the same time, but also ensure that the cylinder head bolts are oiled quickly, evenly and in small amounts. At the same time, the oiling angle and oiling amount can be accurately controlled to adapt to different oiling requirements.

[0012] 3. The oiling device of the present invention adopts a filter structure, which can remove excess oil while spraying oil.

[0013] 4. The oil coating device of the present invention adopts an oil receiving pan structure, which can recover excess oil while spraying oil.

[0014] 5. The oiling device of the present invention adopts a handlebar and wheel structure design, which is convenient for moving the oiling device. BRIEF DESCRIPTION OF THE DRAWINGS
