Abstract
The invention relates to a repeated cylinder sleeve pressing technology of a cylinder block, which comprises the steps of cylinder sleeve pressing, cylinder hole boring, repeated cylinder sleeve pressing, cylinder hole honing, top surface milling, cylinder sleeve pressing, cylinder hole boring, repeated cylinder sleeve pressing, top surface milling and cylinder hole honing. By adopting the repeated cylinder sleeve pressing technology of the cylinder block, clearances generated between faying surfaces of the cylinder sleeve and the cylinder block during processing a cylinder hole are eliminated, and faults such as engine overheat, and the like, which occur in outer fields and are caused by the sinking of the cylinder sleeve of the cylinder block of a gasoline engine, are thoroughly solved.
Description
Technical field
The present invention relates to a kind of processing technology of inlaying the engine cylinder-body of cylinder sleeve.
Background technology
At present; The cylinder sleeve of cylinder block adopts the technology that once press-fits, and cylinder hole process is prone to cause cylinder sleeve rise phenomenon, is prone to produce the gap between cylinder sleeve and cylinder junction surface; The cylinder sleeve of cylinder block is prone to sinkage in the course of work under the effect of cylinder cap pressure, causes faults such as engine overheat.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology, provide a kind of and eliminated cylinder hole between cylinder sleeve and cylinder junction surface and add the cylinder block that produces the gap and repeat Device for pressing cylinder liner technology.
In order to achieve the above object, the technical scheme that adopts of the present invention is: press-fit cylinder sleeve-boring cylinder hole-repetition Device for pressing cylinder liner-honing cylinder hole-mill end face-press-fit cylinder sleeve-boring cylinder hole-repetition Device for pressing cylinder liner-mill end face-honing cylinder hole.
The pressure 5-12bar that press-fits cylinder sleeve of the present invention repeats the pressure 3-8 ton of Device for pressing cylinder liner, press-fits the pressure 5-12bar of cylinder sleeve, repeats the pressure 3-8 ton of Device for pressing cylinder liner.
Advantage of the present invention is:
The present invention has eliminated the gap that cylinder hole between cylinder sleeve and cylinder junction surface adds generation, has thoroughly solved the faults such as engine overheat that cylinder of petrol engine cylinder sleeve that the outfield occurs sinks to cause.
The former technological process of the present invention for once press-fits cylinder sleeve, improves the back technological process behind the part processing content of accomplishing the cylinder hole, and creativeness has increased repetition Device for pressing cylinder liner technology.Promptly adopt more optimal processing process, behind boring cylinder hole, increased the operation that repeats Device for pressing cylinder liner.Adopt forcing press to carry out exerting pressure of one or many again from the top to press-fiting good cylinder sleeve, push back the cylinder hole rise amount that causes because of bore hole through aids such as pressure heads.This repetition Device for pressing cylinder liner technological process has been applied to the processing of 471 serial cylinder bodies, thoroughly solved the faults such as engine overheat that cylinder of petrol engine cylinder sleeve that the outfield occurs sinks to causing
The specific embodiment
Below in conjunction with embodiments of the invention are described in further detail.
Embodiment 1,
