Abstract
The invention discloses a surface roughening method for an engine cylinder hole. The surface roughening method includes the following steps that 1, an engine cylinder is put on a vertical boring machine working table, the diameter of the engine cylinder hole is theta, the engine cylinder hole is formed in the vertical direction, and the bottom of the engine cylinder is an oil bottom shell assembly face and is fixed to the vertical boring machine working table through a positioning hole in the oil bottom shell assembly face; 2, a boring tool is installed on a spindle of a vertical boring machine and extends into the engine cylinder hole to cut the surface of the cylinder hole so that the surface of the cylinder hole can be roughened; 3, iron scraps and cutting fluid inside the engine cylinder hole are cleared off. The surface roughening method for the engine cylinder hole is simple in technology and capable of greatly improving production efficiency.
Description
Technical field
The present invention relates to a kind of engine cylinder-body cylinder holes method for coarsening surface.
Background technology
Roughening before at present engine cylinder-body cylinder holes spraying typically adopts blasting craft, and endoporus sandblasting has a problems with:
(1) remanufacturing cylinder body cylinder holes has oil-bearing layer, needs endoporus is carried out, drying work before sandblasting, needs to increase
Cleaning and drying plant；
(2) complicated, expensive, the residual husky difficult cleaning of domestic at present endoporus abrasive blast equipment scheme；
(3) lead to original size different due to abrasion difference for remanufacturing cylinder body cylinder holes, just need during metal spraying
To measure hole size after sandblasting one by one, calculate coating thickness, change spray parameters, be so unfavorable for industrialization production.
Content 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 cylinder holes surface coarsening side
Method, process is simple, can improve production efficiency,.
For the purpose of the present invention, present invention provide the technical scheme that
A kind of engine cylinder-body cylinder holes method for coarsening surface, comprises the following steps:
(1) engine cylinder-body is placed on vertical boring mill workbench, engine cylinder-body cylinder holes a diameter ofAnd along vertically
Direction is arranged, engine cylinder-body bottom is oil sump fitting surface, is fixed on described vertical by the location hole of oil sump fitting surface
On boring table；
(2) on vertical boring mill main shaft, borer is installed, it is right in described engine cylinder-body cylinder holes that borer is stretched into
Cylinder holes surface carries out machining to realize the roughening on cylinder holes surface；
(3) iron filings in cleaning engine cylinder-body cylinder holes and cutting fluid.
In some embodiments wherein, in described step (2), the diameter of cylinder holes is machined to
Roughness is ra3.2～ra6.3.
In some embodiments wherein, in described step (2), cutting parameter is cutting speed v=40～80m/min,
Feed speed f=0.3～0.1m/min.
With respect to scheme of the prior art, the invention has the advantage that
Using technical scheme, this method of roughening process is simple, equipment investment low cost, solve and start at present
Before the spraying of machine cylinder body cylinder holes, the difficult problem of roughening treatment, improves production efficiency.

A kind of engine cylinder-body cylinder holes method for coarsening surface, with cylinder diameterAs a example the four cylinder cylinder bodies for 65mm, walk including following
Rapid:
(1) engine cylinder-body 4 is placed on vertical boring mill workbench 1, engine cylinder-body cylinder holes 5 is arranged in a vertical direction,
Engine cylinder-body 4 bottom is oil sump fitting surface 6, is fixed on described vertical boring mill work by the location hole 7 of oil sump fitting surface 6
In station 1；
(2) on vertical boring mill main shaft 2, borer 3 is installed, borer 3 is stretched into described engine cylinder-body cylinder holes 5
Interior machining is carried out to realize the roughening on cylinder holes surface to cylinder holes surface, the diameter of cylinder holes is machined to 65.15 ± 0.02mm,
Roughness is ra3.2～ra6.3, and cutting parameter is cutting speed v=40～80m/min, feed speed f=0.3～0.1m/
min；
(3) iron filings in cleaning engine cylinder-body cylinder holes 5 and cutting fluid.
Examples detailed above only technology design to illustrate the invention and feature, its object is to allow one skilled in the art
Will appreciate that present disclosure and implement according to this, can not be limited the scope of the invention with this.All smart according to the present invention
Equivalent transformation or modification that god's essence is done, all should be included within the scope of the present invention.
