Description
Technical field
The invention belongs to a kind of precision cast structure, and in particular to a kind of automobile cylinder cover casting heating stalk structure.
Background technology
Automobile engine is made up of cylinder block and cylinder cover two large divisions, is inter-connected via a bolt joint.
Cylinder cap is arranged on above cylinder body, from top seal cylinder and forms combustion chamber.It is often and high-temperature high-pressure fuel gas
It is in contact, therefore bears very big thermic load and mechanical load.Cooling jacket, cylinder cap are formed with inside the cylinder head of water-cooled engine
The cooling water hole of lower surface communicates with the cooling water hole of cylinder body.The high-temperature parts such as combustion chamber are cooled down using recirculated water.
It is also equipped with Valve seat on cylinder cap, valve guide hole, for being installed into, exhaust valve, also inlet channel and row
Gas passage etc..The hole of installation spark plug is machined with the cylinder head of gasoline engine, and installation spray is machined with the cylinder head of diesel engine
The hole of oily device.Cam shaft bearing bore is also machined with the cylinder head of cammer, to install camshaft.
Cylinder cap is typically cast using gray cast iron or alloy cast iron, and the thermal conductivity of aluminium alloy is good, is advantageous to improve compression ratio, institute
It is used more and more with aluminium alloy cylinder lid in recent years.
But aluminum alloy cylinder cover there is also some problems in casting process.
The content of the invention
The present invention proposes that the purpose is to provide a kind of automobile cylinder cover casting and use to add to solve the problems, such as that prior art is present
Hot stalk structure.
The technical scheme is that：A kind of automobile cylinder cover casting heating stalk structure, including stalk, the liter
I extra set, II extra set, sleeve are cased with outside liquid pipe successively, No. I chamber is formed between the I extra set, II extra set, it is described
No. II chamber is formed between II extra set, sleeve, the II extra set is mutually fixed with bearing, and No. II chamber is provided with winding
Coil on No. II outer casing outer wall.
The stalk upper end forms department of assembly, and the I extra set upper side forms the shoulder hole for accommodating department of assembly.
The I extra set includes the upper snap ring of upper end and the lower snap ring of lower end, and the lower snap ring external diameter is less than outside upper snap ring
Footpath.
The II extra set includes the ladder mounting ring of upper end and the retainer ring of lower end, No. II outer casing internal diameter and lower card
Ring external diameter is identical, and the shoulder hole of the ladder mounting ring is identical with upper snap ring external diameter.
No. I outer casing outer wall, upper snap ring lower surface, lower snap ring upper surface, No. II outer casing inner wall enclose to form No. I chamber
Room.
No. II outer casing outer wall, ladder mounting ring lower surface, retainer ring upper surface, sleeve lining enclose to form No. II chamber
Room.
The retainer ring end face forms through hole, and screw is mutually fixed through above-mentioned through hole with bearing.
The upper snap ring, ladder mounting ring are fixed by radial bolts, the sleeve and ladder mounting ring outer wall it
Between for interference fit.
The present invention reduces heat loss by No. I chamber between I extra set, II extra set, the coil in No. II chamber
Effectively stalk can be avoided to block, avoid casting flaw, present invention reduces energy consumption, improves production efficiency, carries
The high service life of stalk, is applicable in various air injection machines.
Brief description of the drawings
Fig. 1 is the front view of the present invention；
Wherein：
The extra set of 1 stalk 2 I
22 times snap rings of snap ring on 21
3 II extra sets
The retainer ring of 31 ladder mounting ring 32
4 chambers of sleeve 5 I
6 No. II coils of chamber 7.
Embodiment
Hereinafter, referring to the drawings and embodiment the present invention is described in detail：
As shown in figure 1, a kind of automobile cylinder cover casting heating stalk structure, including stalk 1, outside the stalk 1 successively
It is cased with I extra and covers 2, II extra set 3, sleeve 4, I extra, which covers, forms No. I chamber 5 between 2, II extra covers 3, described No. II
No. II chamber 6 is formed between overcoat 3, sleeve 4, the II extra set 3 is mutually fixed with bearing, and No. II chamber 6, which is provided with, to be twined
The coil 7 being wound on II extra, 3 outer walls of set.
The upper end of stalk 1 forms department of assembly, and I extra covers 2 upper ends and forms the shoulder hole for accommodating department of assembly.
The I extra set 2 includes the upper snap ring 21 of upper end and the lower snap ring 22 of lower end, and the lower external diameter of snap ring 22 is less than upper
The external diameter of snap ring 21.
The II extra set 3 includes the ladder mounting ring 31 of upper end and the retainer ring 32 of lower end, and II extra covers 3 internal diameters
Identical with the lower external diameter of snap ring 22, the shoulder hole of the ladder mounting ring 31 is identical with the upper external diameter of snap ring 21.
The I extra set, 2 outer walls, the lower surface of upper snap ring 21, the upper surface of lower snap ring 22, II extra cover 3 inwalls and enclose to form I
Number chamber 5.
The II extra set, 3 outer walls, the lower surface of ladder mounting ring 31, the upper surface of retainer ring 32, the inwall of sleeve 4 enclose to be formed
