Bowl-shaped plug assembly tool and application method thereof

Abstract

The invention discloses a bowl-shaped plug assembly tool. The bowl-shaped plug assembly tool is used for plugging an oblique oil channel of a cylinder body. Threaded holes are formed in the peripheryof the oblique oil channel of the cylinder body. The bowl-shaped plug assembly tool comprises a push rod assembly, a pressing plate and a locating seat. According to the structure of the push rod assembly, a rod tail is located at one end of the push rod assembly and is provided with a thread; a limiting ring is provided with an internal thread; a punch head is located at the other end of the pushrod assembly and used for pushing and sleeving a bowl-shaped plug. A big-end-up pressing plate oblique stepped hole is formed in the middle position of the pressing plate. The inner diameter of the small end of the pressing plate oblique stepped hole is less than the outer diameter of the limiting ring. A big-end-down locating seat oblique stepped hole is formed in the middle position of the locating seat. The push rod assembly with the rod tail upwards first penetrates through the locating seat oblique stepped hole, then penetrates through the pressing plate oblique stepped hole and finallylocks and fixes the limiting ring onto the rod tail. The inclination of the pressing plate oblique stepped hole and the locating seat oblique stepped hole is the same as the inclination of the obliqueoil channel. The bowl-shaped plug assembly tool is simple in structure, convenient to operate and capable of improving the installation efficiency and quality of the bowl-shaped plug.

Description

technical field [0001] The invention relates to the technical field of assembly technology of internal combustion engines, in particular to a bowl-shaped plugging assembly tool for blocking inclined oil passages of a cylinder block and a use method thereof. Background technique [0002] Due to the layout requirements of the lubrication system of the internal combustion engine, various oil passages are often arranged on the cylinder block, and of course the design of inclined oil passages is inevitable. The machined orifices of these passages require assembly plugs to seal. [0003] Bowl-shaped plug is one of the most commonly used standard parts in the field of mechanical design. Because of its simple structure, excellent sealing performance and low cost, it is often used for sealing the lubricating oil passage of internal combustion engines. When the bowl-shaped plug is used, in order to ensure good sealing performance, the bowl-shaped plug and the plug hole are designed a...

AI Technical Summary

Problems solved by technology

[0005] The traditional method of assembling the inclined oil channel bowl plug has the following disadvantages: 1. The installation efficiency is low; 2. Due to the uncertainty of the workers’ assembly and tapping direction, the bowl plug is very easy to knock, and the installation position cannot be guaranteed to be completely consistent with the plug hole. If the orientation is consistent, it is prone to poor sealing and even the failure of the bowl-shaped plug to fall off, which will bring major safety hazards to the internal combustion engine
