Abstract
The utility model relates to an internal combustion engine cylinder pore structure comprising an internal combustion engine cylinder block and a cylinder bore spigot plane, wherein the contact area of the cylinder bore spigot plane and the spigot with the check tool is larger than 80 percent. The processing tool of the internal combustion engine cylinder pore structure is a disk structure grinding tool made of cast iron; the lower end surface of the disk structure is a grinding end surface; and the flatness of the grinding end surface is less than 0.01. Through grinding the cylinder bore spigot plane, the internal combustion engine cylinder pore structure improves the roughness and flatness of the spigot plane, ensures the contact between a cylinder sleeve and the cylinder bore spigot to be more tight, and solves the leakage problem due to poor sealing caused by the large height difference of the cylinder sleeve protruding out of the cylinder bore.
Description
Technical field
The utility model relates to a kind of internal combustion (IC) engine cylinder hole structure and this internal combustion (IC) engine cylinder hole structure machining tool.
Technical background
Internal-combustion engine for the dress cylinder sleeve, it is a very important size that cylinder sleeve protrudes the cylinder block apical side height, the cylinder sleeve protrusion height directly is subjected to the influence of the quality of processing on seam plane, cylinder hole, if protrusion height is not controlled, can reduce the sealability of sealing gasket between the cylinder block and head, cause the cylinder hole to leak, influence the normal use of internal-combustion engine.
IC engine cylinder bore seam plane directly processes with cutter at present, and the roughness on seam plane is more than Ra1.6, and the planeness of seam is generally more than 0.05.Behind the dress cylinder sleeve, the area of contact of cylinder sleeve and seam is generally below 65%, and the cylinder sleeve protrusion height can change behind the internal combustion engine, influences the sealing of cylinder block and head, causes cylinder hole water leakage ratio height, and engine failure is frequent.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of internal combustion (IC) engine cylinder hole structure that improves cylinder block and cylinder head sealing effect, and a kind of machining tool of processing this internal combustion (IC) engine cylinder hole structure is provided simultaneously.
The utility model internal combustion (IC) engine cylinder hole structure comprises internal combustion engine cylinders and seam plane, cylinder hole, and seam plane, cylinder hole contacts the area of contact of cubing greater than 80% with the seam area of contact.
The utility model internal combustion (IC) engine cylinder hole structure machining tool is castiron disc structure abrasive tool, and the lower end surface of disc structure is a face machined flat, and the planeness of face machined flat is less than 0.01.
The cylinder hole seam plane lapping technology of the utility model internal combustion (IC) engine cylinder hole structure is: wipe clean the foreign matters such as iron filings on seam plane and the abrasive tool before the grinding, on abrasive tool and seam plane, coat grinding paste, abrasive tool is put seam plane, cylinder hole, on abrasive tool, apply the pressure of 20～30N, rotate abrasive tool 5～10 circles.Wipe clean the grinding paste on the seam plane then, on seam area of contact contact cubing, be coated with the area of contact that red lead powder is checked seam plane and cubing, area of contact greater than 80% need not grinding, otherwise continue as stated above to grind, up to area of contact greater than 80%.
Description of drawings
Fig. 1 is the utility model internal combustion (IC) engine cylinder hole structure and cylinder sleeve assembly structure schematic representation;
Fig. 2 is this usefulness internal combustion engine cylinder hole structure machining tool structural representation.
Among the figure: the 1-cylinder sleeve; 2-seam plane; The 3-cylinder body; The 4-abrasive tool; The 5-face machined flat.
Embodiment
Further specify the utility model structure and processing method below in conjunction with accompanying drawing.
The utility model internal combustion (IC) engine cylinder hole structure comprises internal combustion engine cylinders 3 and seam plane, cylinder hole 2, seam plane, cylinder hole, and cylinder sleeve 1 is installed in the cylinder body 3 and contacts with seam plane, cylinder hole 2.
The utility model internal combustion (IC) engine cylinder hole structure machining tool is castiron disc structure abrasive tool 4, and the lower end surface of disc structure is a face machined flat 5, and the planeness of face machined flat is less than 0.01.
Before the grinding, wipe clean seam plane 2 and face machined flat 5, and on seam plane 2 and face machined flat 5, coat grinding paste, then abrasive tool 4 is put on the cylinder hole, seam plane 2 and face machined flat 5 are adjacent to, apply the power of 20-30N to abrasive tool 4 by hand, rotate abrasive tool 5～10 circles, wipe clean seam plane 2 then, evenly coat red lead powder with seam area of contact cubing, whether the area of contact of checking seam plane 2 and inspection is greater than 80%, if can load onto cylinder sleeve 1 by the subsequent technique requirement greater than 80%, otherwise continue to grind as stated above, up to area of contact greater than 80%.
The utility model internal combustion (IC) engine cylinder hole structure and machining tool, can effectively improve the area of contact of seam plane and cylinder sleeve, guarantee cylinder sleeve protrusion height H, and protrusion height variation in cylinder hole is very little after the assurance engine operation, effectively solves internal-combustion engine because cylinder sleeve protrudes the bad seepy question that causes of sealing that cylinder hole height difference causes greatly.
Claims (2)
