Description
Technical field
The utility model belongs to machining technology field, is related to a kind of cast iron cylinder cover.
Background technology
Cylinder jacket is divided into wet type and dry type, and existing wet type and dry cylinder generally first carry out roughing work when being enclosed on processing
Sequence, then carries out finishing step again.The specific processing technology of wet liner is：Cut two ends, turning → heavy boring endoporus (or
Heavy boring endoporus → cut two ends, turning) → half fine turning outer circle → right boring (or finish reaming) → smart car support shoulder and water channel → cuts supporting
Shoulder breadth degree → cut the water sealed tank → upper and lower waistband of corase grind endoporus → smart car → fine grinding endoporus.The specific processing technology of dry liner
It is：Cut two ends, turning → heavy boring endoporus (or heavy boring endoporus → cut two ends, turning) → half fine turning outer circle → right boring (or essence
Hinge) → fine turning outer circle → smart car support shoulder width → corase grind endoporus → thick centreless grinding → fine grinding → essence centreless grinding.
The something in common of wet type and dry liner is：It is cylindrical for positioning datum with cylinder jacket when processing endoporus；Outside car
Using cylinder cover inner hole as positioning datum when circle or support shoulder.It is this alternately and repeatedly, the process route of locating and machining benchmark each other, meeting
Make the endoporus after endoporus that initial roughing process is processed or outer circular shape error, particularly roughing, ground no
In the case of, the error of endoporus is bigger, then causes the error of ensuing turning and car support shoulder to increase, surface to be machined enters
Row is replicated repeatedly, and the form error that result in the inside and outside circle of cylinder jacket is replicated and is superimposed repeatedly, forms final products form error
It is bad or overproof.
