Abstract
The present invention provides a kind of cylinder jacket machining process, first carries out roughing process, then carries out rough honing inner hole, then carry out finishing step.The present invention moves to rough honing inner hole after roughing process, namely before finishing step, it right boring or finish reams again and carries out rough honing inner hole after process, make the inner hole of the bistrique of rough honing process honing cylinder jacket under low harmomegathus pressure, to achieve the purpose that remove cylinder jacket inner bore surface surplus and correct inner surface configuration error, it is higher by the inner hole precision of rough honing, error has greatly reduced, so that the error for the fine turning outer circle or smart car support shoulder on the basis of inner hole that finishing step carries out also greatly reduces, substantially situation is superimposed from the error that source has cut off finishing step, to improve in cylinder jacket, the precision of outer circle, comply with standard final cylinder jacket.
Description
Technical field
The invention belongs to technical fields of mechanical processing, are related to a kind of cylinder jacket machining process.
Background technique
Cylinder jacket is divided into wet type and dry type, and existing wet type and dry liner generally first carry out roughing work in processing
Then sequence carries out finishing step again.The specific processing technology of wet liner is: cut both ends, turning → heavy boring inner hole (or
Heavy boring inner hole → cut both ends, turning) → half fine turning outer circle → right boring (or finish reaming) → smart car support shoulder and water channel → cuts bearing
Shoulder breadth degree → cut the water sealed tank → upper and lower waistband of rough honing inner hole → smart car → microhoning inner hole.The specific processing of dry liner
Technique is: cutting both ends, turning → heavy boring inner hole (or heavy boring inner hole → cut both ends, turning) → half fine turning outer circle → right boring
(or finish reaming) → fine turning outer circle → smart car support shoulder width → rough honing inner hole → thick centreless grinding → microhoning → essence centreless grinding.
The something in common of wet type and dry liner are as follows: when processing inner hole, using cylinder jacket outer circle as positioning datum；Outside vehicle
Using cylinder cover inner hole as positioning datum when round or support shoulder.This process route for processing positioning datum alternately and repeatedly, each other, meeting
Inner hole after the inner hole for processing initial roughing process or outer circular shape error, especially roughing, in no carry out top gem of a girdle-pendant
In the case where mill, the error of inner hole is bigger, then causes the error of next turning and vehicle support shoulder to increase, surface to be machined
It is replicated repeatedly, the form error for resulting in the inside and outside circle of cylinder jacket is replicated and is superimposed repeatedly, is formed final products shape and is missed
Difference is bad or overproof.
Summary of the invention
The object of the present invention is to provide a kind of cylinder jacket machining process that can obviously reduce error.
To achieve the above object, the invention adopts the following technical scheme: a kind of cylinder jacket machining process, first carries out thick
Then manufacturing procedure carries out rough honing inner hole, then carries out finishing step.
The cylinder jacket is wet liner.
The roughing process are as follows: cut turning behind liner blank both ends, then carry out heavy boring inner hole, or first to cylinder jacket
Blank heavy boring inner hole, then cut both ends, turning；Then half fine turning outer circle is carried out, or is finish reamed.
The finishing step are as follows: then first smart car support shoulder and water channel carry out cutting support shoulder width again and cut water sealed tank,
Finally carry out the upper and lower waistband of smart car and microhoning inner hole.
The cylinder jacket is dry liner.
The roughing process are as follows: cut turning behind liner blank both ends, then carry out heavy boring inner hole, or first to cylinder jacket
Blank heavy boring inner hole, then cut both ends, turning；Then half fine turning outer circle is carried out again, or is finish reamed.
The finishing step is first to carry out fine turning outer circle, then carries out smart car support shoulder width and thick centreless grinding again, most
Microhoning and smart centreless grinding are carried out afterwards.
After rough honing inner hole is moved to roughing process by the present invention, that is, before finishing step, then right boring or essence
It cuts with scissors process and carries out rough honing inner hole later, make the inner hole of the bistrique of rough honing process honing cylinder jacket under low harmomegathus pressure,
With achieve the purpose that remove cylinder jacket inner bore surface surplus and correct inner surface configuration error, by rough honing inner hole precision compared with
Height, error have greatly reduced, so that the mistake for the fine turning outer circle or smart car support shoulder on the basis of inner hole that finishing step carries out
Difference also greatly reduces, and substantially situation is superimposed from the error that source has cut off finishing step, so that it is inside and outside to improve cylinder jacket
Round precision complies with standard final cylinder jacket.
Specific embodiment
Embodiment 1: the mechanical processing technique of wet liner: turning behind liner blank both ends is cut, then carries out heavy boring

Embodiment 2: the mechanical processing technique of wet liner: first to liner blank heavy boring inner hole, then both ends are cut, outside vehicle
Circle, then carries out half fine turning outer circle, finish reams；Then rough honing inner hole, then smart car support shoulder and water channel carry out cutting bearing shoulder breadth again
Water sealed tank is spent and cut, the upper and lower waistband of smart car and microhoning inner hole is finally carried out, obtains cylinder jacket finished product.
Embodiment 3: the mechanical processing technique of dry liner: turning behind liner blank both ends is cut, then carries out heavy boring
Then inner hole carries out half fine turning outer circle, right boring again；Rough honing inner hole, then fine turning outer circle is carried out, smart car support shoulder is then carried out again
Width and thick centreless grinding finally carry out microhoning and smart centreless grinding, obtain cylinder jacket finished product.
Embodiment 4: the mechanical processing technique of dry liner: first to liner blank heavy boring inner hole, then both ends are cut, outside vehicle
Circle, then carries out half fine turning outer circle again, finish reams；Rough honing inner hole, then fine turning outer circle is carried out, smart car bearing shoulder breadth is then carried out again
Degree and thick centreless grinding finally carry out microhoning and smart centreless grinding, obtain cylinder jacket finished product.
Certainly, the above description is not a limitation of the present invention, and the present invention is also not limited to the example above, the art
