Problems solved by technology

[0004] The shortcoming that the above-mentioned diesel engine cylinder block immersion oil antirust method exists is: the antirust oil is filled in the blind hole of the cylinder head bolt of the diesel engine cylinder block top surface, for the storage of large quantities, the waste that causes is very considerable; The weight of the finished heavy-duty diesel engine cylinder block is generally more than 200kg. If you want to pour out the oil in the blind hole of the cylinder head bolt, the only way is to design and manufacture special diesel engine cylinder block oil pouring and turning mechanical power equipment, add a process, and increase site and operators, which is uneconomical and creates new waste

Embodiment Construction

[0018] Further description will be made below in conjunction with the accompanying drawings and the oil-immersed rust prevention method for diesel engine cylinder blocks that can reduce oil-immersion waste according to the present invention.

[0019] see figure 1 , figure 2 , image 3 As shown, it includes a diesel engine cylinder block 1, a cylinder head bolt blind hole 2, a first positioning hole 3, a second positioning hole 31, a cylinder pin 4, a plastic mold 5, a first positioning pin 6, and a second positioning pin 61.

[0020] The oil immersion antirust method of the diesel engine cylinder block that can reduce the oil immersion waste of the present invention comprises the following steps:

[0021] 1. Pour the anti-rust oil just enough to submerge the cylinder block 1 of the diesel engine into the fuel tank;

[0022] 2. Insert cylindrical pins 4 that fit in clearance with cylinder head bolt blind holes 2 into the cylinder head bolt blind holes 2 on the top surface o...

Abstract

The invention relates to a diesel engine cylinder oil immersion antirust method capable of reducing oil immersion waste. The method comprises the following steps: pouring antirust oil for immersing a diesel engine cylinder into a fuel tank; respectively inserting cylindrical pins in clearance fit with cylinder head bolt blind holes into the cylinder head bolt blind holes on the top of the diesel engine cylinder; making positioning holes on the diesel engine cylinder; arranging positioning pins matched with the positioning holes on the cylindrical pins and respectively inserting the cylindrical pins into corresponding cylinder head bolt blind holes; and when the diesel engine cylinder is completely immersed in the fuel tank, lifting the diesel engine cylinder out, packaging by using a plastic bag, and storing in a warehouse for a long time. After the diesel engine cylinder is immersed in oil, the oil is only attached to the inner surfaces of the cylinder head bolt blind holes and is not filled in the whole cylinder head bolt blind holes, so that the aim of reducing the cost is fulfilled, and the method is economic, practical and high-efficiency and meets the requirement for volume production.

Description

technical field [0001] The invention relates to an oil immersion antirust method for a diesel engine cylinder body, in particular to an oil immersion antirust method for a diesel engine cylinder body capable of reducing oil immersion waste, and belongs to the technical field of mechanical equipment. Background technique [0002] There are 26 blind holes for cylinder head bolts on the top surface of the six-cylinder diesel engine cylinder block. At present, the diesel engine cylinder block manufacturers, for the finished diesel engine cylinder blocks that are not directly installed, must be dipped in oil to prevent rust before being stored in the warehouse after machining. deal with. [0003] The currently commonly used diesel engine cylinder block immersion oil rust prevention method includes the following steps: ⑴ Pour into the fuel tank just enough antirust oil to immerse the diesel engine cylinder block; ⑵ Fully immerse the diesel engine cylinder block in the fuel tank; ...
