Problems solved by technology
[0003] At present, the engine assembly line basically separates the handle part of the tooling main body from the oil seal guide rod, which cannot ensure the vertical requirements of the oil seal guide rod and the handle part. At the same time, the gap between the oil seal press-fitting surface and the top surface of the valve guide is not easy to control; this phenomenon It is easy to cause the valve oil seal to not be pressed in place, the pressure is biased, and the lip is deformed

Embodiment Construction
[0034] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.
[0035] An overall head-changing valve oil seal frock structure, including the handle part (1) of the main body of the frock, the oil seal guide rod (2) of the frock body, and the head cap (3); the valve oil seal (4) is passed through the guide rod (2) of the frock body ) into the frock head cap (3), and press it into the valve guide (5) of the cylinder head (6) assembly. The handle part (1) of the main body of the tooling and the oil seal guide rod (2) of the main body of the tooling are processed as a whole, collectively referred to as the main body of the tooling; four bolt holes (7) and two observation holes (8) are provided on the tooling head cap (3) ), the frock head cap (3) is fastened and assembled with the frock body (2) through four bolt holes (7). Process the handle part (1) ...

The invention relates to an integral head-changing type valve oil seal tool and a using method thereof. The integral head-changing type valve oil seal tool comprises a tool body, a tool head cap, a valve oil seal, a cylinder cover assembly and a valve guide pipe, wherein the valve guide pipe is arranged on the cylinder cover assembly; the tool body penetrates through the valve oil seal; the valve oil seal is arranged in the tool head cap via the tool body and is mounted on the valve guide pipe in a press-fitting manner; and the tool head cap is used for limiting the press-fitting of the valve oil seal. The tool body comprises a handheld part and an oil seal guide rod, and the handheld part and the oil seal guide rod are integrally machined and formed.
Description
technical field [0001] The invention belongs to the field of engine design, and in particular relates to the design of a valve oil seal integral replacement tool. Background technique [0002] The function of the valve oil seal is to seal the valve stem, and isolate the oil mixture in the crankcase from entering the combustion chamber through the gap between the valve stem and the valve guide hole, causing the whole machine to burn oil; or the mixture in the combustion chamber enters through the gap Valve cover, crankcase, causing positive crankcase pressure. During the assembly process of the valve oil seal, it is easy to appear that the valve oil seal is not pressed properly, the pressure is biased, the lip is deformed, etc. These situations will lead to the failure of the oil seal and the phenomenon of burning oil in the whole machine. A very important part. [0003] At present, the engine assembly line basically separates the handle part of the tooling main body from t...
