Embodiment Construction

[0011] 1. Choose a reasonable process flow and processing method

[0012] The machining of the inner hole of the cylinder liner is completed by rough boring, fine boring and honing. The rough boring process mainly removes large machining allowances to provide reliable machining guarantee for subsequent fine boring. The fine boring process not only removes most of the machining allowance and ensures the uniformity and accuracy of the honing allowance, but more importantly, ensures the position accuracy of the inner hole of the cylinder liner and the shape tolerance such as the cylindricity of the inner hole, providing a good processing basis for the honing process .

[0013] The honing process is divided into three stages: rough honing, semi-finish honing and fine honing. In order to fully expose the graphite, the inner hole of the cylinder liner is processed in alternating directions of rotation. The boring tool rotates right when boring, the grinding head rotates left durin...

Abstract

The invention relates to an alternating direction of rotation honing cylinder jacket platform cob webbing technique that is used to facilitate the oil storage and lubrication feature of the engine friction, extend durability, reduce engine oil consumption, improve engine tail gas emission quality, for the benefit of environment protection and human health. Through alternating direction rotation honing cylinder jacket platform cob webbing, it can expose the graphite sufficiently, timely release lubrication oil to the friction system. This technique has acquired international standard parameter, allowing the inner wall of the cylinder jacket acquiring small platform and deep slot, increase bearing area of the small platform, with the deep slot storing oil better, improving sealing capacity, reducing oil consumption, allowing the engine tail gas emission reaching Euro III standard for the benefit of environment protection and health of mankind.

Description

technical field [0001] The invention relates to a technology for honing cylinder liner platform reticulation in alternate rotation directions, which helps to enhance the oil storage and lubrication performance of engine friction pairs, prolongs the service life of the engine, significantly reduces engine oil consumption, improves the quality of engine exhaust emissions, and is beneficial to environmental protection and human health. Background technique [0002] At present, the country's automobile industry is developing rapidly, and the number of automobiles is increasing day by day, but the pollution of the natural environment by the harmful pollutants emitted by the engine exhaust is increasing day by day. Especially the pollution to the city is more prominent. The traditional cylinder liner texture manufacturing technology cannot effectively achieve the performance of oil storage and auxiliary lubrication, and the oil consumption is high, which cannot meet the current hi...
