Abstract
The invention discloses a kind of engine cylinder-body spindle hole restorative procedure, comprise the following steps: (1) boring spindle hole for the first time, unify engine cylinder-body spindle hole size by machining；(2) spraying, by coating coating to engine spindle hole；(3) boring spindle hole for the second time, repairs spindle hole by machining.The engine cylinder-body spindle hole restorative procedure that the present invention provides, technique is simple, easy to operate, recovers the original size of engine cylinder-body spindle hole, cost-effective and raw material in the case of not changing structure.
Description
Technical field
The present invention relates to a kind of engine cylinder-body spindle hole restorative procedure.
Background technology
The big spindle hole of boring is typically taked in engine cylinder hole reparation at present, manufactures and carries out assembling mode with outer ring thickening bearing shell.
This reparation means have a problems with:
(1) change the original design of cylinder body spindle hole and structure, spindle hole will be affected to the bearing capacity of bent axle and master
The structural strength of axis hole；
(2) the bearing shell buying difficulty of specific customization, cost is high；
(3) having several specification due to the big spindle hole of boring, during assembling, the hidden danger of the useful mistake of bearing shell, affects overall performance；
(4) bearing shell size can not quickly be identified during repair and replacement, it is impossible to be quickly found out the new bearing shell for changing,
Have influence on maintenance efficiency.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of engine cylinder-body spindle hole restorative procedure,
Technique is simple, recovers the original size of engine cylinder-body spindle hole, cost-effective and raw material in the case of not changing structure.
For the purpose of the present invention, present invention provide the technical scheme that
A kind of engine cylinder-body spindle hole restorative procedure, comprises the following steps:
(1) boring spindle hole for the first time, unifies engine cylinder-body spindle hole size by machining；
(2) spraying, by coating coating to engine spindle hole；
(3) boring spindle hole for the second time, repairs spindle hole by machining.
In some embodiments wherein, in described step (1), the first boring spindle hole comprises the following steps:
A () cylinder body clamping, assembles dowel hole as positioning datum with engine cylinder-body cylinder holes or cylinder cap, is fixed on by cylinder body
On the support column of mechanical processing worktable；
B () benchmark adjusts, by height and the position of cylinder body of regulation support column, make five spindle hole axial lines of cylinder body
With table surface depth of parallelism ＜ 0.05mm；
C () stationary housing, fixes cylinder body on the table；
D () boring spindle hole, is machined to spindle hole diameter For spindle hole aperture, roughness Ra
3.2～6.3, spindle hole cylindricity ＜ 0.03mm.
In some embodiments wherein, in described step (2), spraying coating process uses plasma spraying, uses iron-based material
Material sprays.
In some embodiments wherein, the diameter of engine cylinder hole is sprayed in (2) by described step
In some embodiments wherein, the diameter of engine cylinder hole is machined in (3) by described stepRecover spindle hole roughness, axiality and circularity.
Relative to scheme of the prior art, the invention have the advantage that
Using technical scheme, this engine cylinder-body spindle hole restorative procedure technique is simple, and operation is implemented convenient,
Need not repair cylinder holes by assembling bearing shell, engine cylinder pore structure need not be changed, save material, reduce production cost.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are for illustrating
The present invention and be not limited to limit the scope of the present invention.The implementation condition used in embodiment can be done according to the condition of concrete producer
Adjusting further, not marked implementation condition is usually the condition in normal experiment.
A kind of engine cylinder-body spindle hole restorative procedure, as a example by 465 cylinder body repairs, spindle hole diameterFor 55+0.02/
0mm, cylinder body length 400mm, comprise the following steps:
(1) boring spindle hole for the first time, unifies engine cylinder-body spindle hole size by machining, comprises the following steps:
A () cylinder body clamping, assembles dowel hole as positioning datum with engine cylinder-body cylinder holes or cylinder cap, is fixed on by cylinder body
On the support column of mechanical processing worktable；
B () benchmark adjusts, by height and the position of cylinder body of regulation support column, make five spindle hole axial lines of cylinder body
With table surface depth of parallelism ＜ 0.05mm；
C () stationary housing, fixes cylinder body on the table；
D () boring spindle hole, is machined to 55.3 ± 0.03mm by spindle hole diameter,For spindle hole aperture, roughness Ra
3.2～6.3, spindle hole cylindricity ＜ 0.03mm.；
(2) plasma spraying, uses iron by coating coating in engine spindle hole, straight by engine cylinder hole
Footpath is sprayed into 54.8 ± 0.03mm；
(3) boring spindle hole for the second time, is machined to 55 (+0.02/0) mm by machining by the diameter of engine cylinder hole,
Recover spindle hole roughness, axiality and circularity to production requirement.
Examples detailed above, only for technology design and the feature of the explanation present invention, its object is to allow one skilled in the art
Will appreciate that present disclosure and implement according to this, can not limit the scope of the invention with this.All according to present invention essence
God's equivalent transformation of being done of essence or modification, all should contain within protection scope of the present invention.
