Description

Engine valve oil seal mounting tool
Technical Field
The utility model belongs to the technical field of the engine oil blanket installation, especially, relate to an engine valve oil blanket mounting tool.
Background
The valve oil seal is one kind of oil seal, generally by outer frame and fluororubber common vulcanization form, and self-tightening spring or steel wire are installed to oil blanket footpath oral area for the sealed of engine valve guide arm, and the valve oil seal can prevent that machine oil from getting into the admission and exhaust pipe, avoids machine oil to run off, prevents that the mist and the exhaust gas of petrol and air from leaking, prevents that engine machine oil from getting into the combustion chamber. Since a valve oil seal is one of important parts of an engine valve assembly and comes into contact with gasoline and engine oil at high temperatures, it is necessary to use a material having excellent heat resistance and oil resistance, and it is generally made of fluororubber.
When the engine valve oil seal is installed, the lubricating oil sealing washer is easy to be damaged due to uneven stress or collision with threads of the valve rod and the shaft end, and the working efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
To the above circumstances, for overcoming prior art's defect, the utility model provides an engine valve oil blanket mounting tool makes things convenient for lubricating oil seal ring's installation, and its simple structure, preparation convenience, and the problem in the background art has been solved in the facilitate promotion application.
The utility model adopts the technical scheme as follows: the utility model provides an engine valve oil seal mounting tool, includes oil blanket mounting tool main part, oil blanket mounting tool main part upper end is conical, the lower extreme of oil blanket mounting tool main part is cylindric, oil blanket mounting tool main part upper end is the oil blanket and gets into the end, the lower extreme and the axle head threaded connection of oil blanket mounting tool main part, the lower extreme opening part of the cylindric part of oil blanket mounting tool main part is equipped with the chamfer contact surface with axle head chamfer assorted.
Further, the opening at the lower end of the main body of the oil seal installation tool is in a shape of a flat and smooth ring.
Further, the oil seal is connected with the oil seal installation tool main body through a shaft end and a thread and is pushed to the oil seal entering end.
Furthermore, the chamfer of the shaft end is mutually attached to the chamfer contact surface of the oil seal mounting tool body.
After the structure is adopted, the utility model discloses beneficial effect as follows: the utility model provides a pair of engine valve oil blanket mounting tool makes things convenient for the installation of lubricating oil seal ring, avoids having improved work efficiency because of the uneven damage that causes of colliding with the screw thread of valve rod, axle head of lubricating oil seal ring atress. The structure is simple, the manufacture is convenient, and the popularization and the application are convenient.
