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 new automobile cylinder cap casting to solve the problems, such as that prior art is present
With heating stalk structure.
The technical scheme is that：A kind of new automobile cylinder cap casting heating stalk structure, including stalk, institute
To state and be cased with I extra set, II extra set outside stalk successively, the I extra set, II extra cover is cased with III extra set outside, and described III
Extra set is outer to be cased with sleeve, and No. I chamber, the II extra set and III extra set are formed between the I extra set and III extra set
Between form No. II chamber, No. III chamber is formed between III extra set and sleeve, winding is provided with No. III chamber
Coil on No. III 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 include the upper connection ring of upper end and the lower support ring of lower end, the upper connection ring, lower support ring, lower card
Ring external diameter is identical.
The III extra set includes the ladder mounting ring of upper end and the retainer ring of lower end, No. III 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.
Enclose to form No. I between No. I outer casing outer wall, upper snap ring lower surface, lower snap ring upper surface, No. III outer casing inner wall
Chamber, enclose to be formed between No. II outer casing outer wall, upper connection ring lower surface, lower support ring upper surface, No. III outer casing inner wall
No. II chamber.
No. III outer casing outer wall, ladder mounting ring lower surface, retainer ring upper surface, sleeve lining enclose to form No. III 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 waste by No. I chamber between I extra set, II extra set and III extra set, No. II chamber
Lose, No. III chamber midline circle effectively can avoid stalk from blocking, avoid casting flaw, reduce energy consumption, improve
Production efficiency, casting flaw is avoided, improve the service life of stalk.
