Description
Technical field
The utility model is related to a kind of cylinder head, more particularly to a kind of cylinder head, is mainly used in automobile hair
Motivation field.
Background technology
Aluminum alloy cylinder cover is the kernel component of automobile engine assembly, and cylinder cap is arranged on above cylinder body, with cylinder body
Partial cylinders constitute combustion chamber.Cylinder head is the part of combustion chamber, the shape of combustion chamber to the performance impact of engine very
Greatly, entering and exhaust channel constitutes a stable combustion system with the combustion chamber in cylinder head.If the inlet and outlet road technology of cylinder head
Index any one is undesirable, it will cause significant impact to engine, it may be said that the performance of cylinder head is largely
Dependent on the two technical conditions.Current cylinder cap is individual layer air flue, and combustion-chamber shape and requirement for height are also relatively easy, with
Automobile industry is continued to develop, to meet national emission request, and air cylinder head structure is also constantly being innovated, and present many cylinder caps are equal
Exhaust duct above and below being, and combustion chamber requirement for height and shape need are high.
Traditional mould structure mode is difficult the performance requirement for meeting complicated cylinder cap, and upper and lower exhaust duct is difficult positioning,
Deviation is also easy to produce during assembling, it is easy to occur that air flue Tumble and swirl is unqualified, the technical problem such as combustion chamber volume is overproof.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of cylinder head, the cylinder head can not only ensure upper and lower
The position accuracy of exhaust duct；It can also farthest reduce the volume deviation of combustion chamber simultaneously.
To solve above technical problem, the utility model adopts the technical scheme that a kind of cylinder head, including and base and
The combustion chamber on base is installed on, epithelium healing, downtake are provided with above combustion chamber, it is characterised in that described downtake two ends
Alignment pin is respectively equipped with, in the pin-and-hole on its lower end alignment pin insertion locating piece, determining in its upper end alignment pin insertion epithelium healing
In the hole of position；Described locating piece is fixedly connected with base.
Further, described locating piece be provided with downtake section phase and locating slot, described downtake one end is put
It is fixed in the pin-and-hole that locating piece is inserted in locating slot and by alignment pin.
Further, fixing hole is provided with the corresponding position of the base, mounting hole is provided with locating piece and is passed through
Pin two ends are inserted respectively to be fixedly connected in mounting hole and fixing hole with base.
Further, described combustion chamber is installed on base, and adjusting gasket and regulating bolt are provided with the bottom of combustion chamber,
The adjustment section bolt is connected through base with pad.
The beneficial effects of the utility model are, by setting locating piece and alignment pin, mutually to consolidate with base first with locating piece
It is fixed, then the uniformity of epithelium healing and downtake holding position is made by alignment pin, so can farthest be easy to epithelium healing with
The location and installation of downtake, it is ensured that the performance of engine.
Brief description of the drawings
Fig. 1 is a kind of detonation configuration figure of cylinder head in the present embodiment
Fig. 2 is a kind of combustion chamber section view assembling figure of cylinder head in the present embodiment
Fig. 3 is combustion chamber and epithelium healing and the three-dimensional structure diagram of downtake in the present embodiment
Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As Figure 1-3, a kind of cylinder head of the utility model, including and base 1 and the combustion chamber 2 that is installed on base 1,
Epithelium healing 3, downtake 4 are provided with the top of combustion chamber 2, the described two ends of downtake 4 are respectively equipped with alignment pin 5, the positioning of its lower end
In pin-and-hole on the insertion locating piece 6 of pin 5, in the positioning hole in its upper end alignment pin 5 insertion epithelium healing 3；Described locating piece 6 with
Base 1 is fixedly connected；By setting locating piece 6 and alignment pin 5, mutually fixed with base 1 first with locating piece 6, then pass through positioning
Pin 5 makes the uniformity of epithelium healing 3 and the holding position of downtake 4, so can farthest be easy to epithelium healing 3 and downtake 4
Location and installation, it is ensured that the performance of engine.
In the present embodiment, in order to ensure the degree of accuracy positioned, described locating piece 6 is provided with and the section phase of downtake 4
With locating slot 7, described one end of downtake 4, which is placed in locating slot 7 and passes through alignment pin 5, inserts solid in the pin-and-hole of locating piece 6
It is fixed.By setting locating slot 7, further it can be so accurately positioned using locating slot 7 by the position of downtake 4, with determining
Position pin 5 is engaged, and can be carried out double definition to downtake 4, be effectively improved the positional precision of downtake 4 and epithelium healing 3.
In the present embodiment, fixing hole is provided with the corresponding position of the base 1, provided with installation on locating piece 6
Hole and being inserted respectively in mounting hole and fixing hole by the two ends of pin 8 is fixedly connected with base 1.
In the present embodiment, for the ease of the volume deviation of reduction combustion chamber 2, described combustion chamber 2 is installed on base 1
On, adjusting gasket 8 and regulating bolt 9 are provided with the bottom of combustion chamber 2, the regulating bolt is connected through base 1 with pad 8.
Above-described embodiment is not construed as to limitation of the present utility model, but any made based on spirit of the present utility model
Improve, all should be within protection domain of the present utility model.
