Abstract
The utility model relates to a kind of spark plug lining, comprises bush body, and the outer wall of bush body is metal level, and the corresponding end that bush body coordinates with cylinder head is layers of copper, and the cooperation place of layers of copper and cylinder head forms sealing surface.The beneficial effects of the utility model: spark plug lining bulk strength is high, pressurized is not yielding, and good airproof performance, processing and manufacturing is simple, low cost of manufacture.
Description
Technical field
The utility model relates to a kind of spark plug lining.
Background technology
Existing spark plug lagging material is brass, and brass material plasticity is good, is easy to distortion, finally can makes poorly sealed between lining and cylinder cap and cause cylinder head to be leaked after it is pressed into cylinder head.
Another kind of spark plug lagging material is stainless steel, and stainless steel lining hardness height is not yielding, but to the machining accuracy of cylinder head and lining mating surface and Geometrical Tolerance Principle very high, otherwise cannot reach seal request, processing cost is higher.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of spark plug lining, exists use the technical problem that sealing is poor and processing request is high with the spark plug lining solving existing use.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of spark plug lining, comprises bush body, and the outer wall of described bush body is metal level, the corresponding end that described bush body coordinates with cylinder head is layers of copper, and the cooperation place of described layers of copper and described cylinder head forms sealing surface.
As improving further, described metal level is stainless steel layer.
As improving further, the thickness of described layers of copper is 0.3mm-0.5mm.
After have employed technique scheme, the beneficial effects of the utility model are:
Because spark plug lining is the bush body be made up of stainless steel and brass integral type, namely spark plug liner body material is stainless steel layer, lining and cylinder head mating surface place material are layer of brass, and stainless steel layer makes spark plug lining bulk strength high as material of main part, and pressurized is not yielding; Because the plasticity of brass is good, compressive deformation can well form the sealing with cylinder head cooperation place, and therefore processing is simple, and cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure, 1, bush body, 2, stainless steel layer, 3, layers of copper.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in fig. 1, a kind of spark plug lining, comprises bush body 1, the outer wall of bush body 1 is metal level, the corresponding end that bush body 1 coordinates with cylinder head is layers of copper 3, and the thickness of layers of copper 3 is 0.3mm-0.5mm, and layers of copper 3 forms sealing surface with the cooperation place of cylinder head.
Metal level can adopt stainless steel layer 2.Stainless steel layer 2, as the material of main part of bush body 1, also can adopt other satisfactory metal materials certainly.
Spark plug bush body as shown in Figure 1 can be made according to following manufacturing process: the utility model is first processed and obtained roughing spark plug lining, copper water pouring basin is processed below roughing spark plug lining, utilize the fusing point of copper this physical characteristic lower than stainless steel fusing point, copper water is filled above-mentioned pouring basin, treat that copper water cooling is shaped, processing obtains fine finishining spark plug lining further on this basis, after fine finishining, spark plug liner body is the stainless steel layer 2 that stainless steel material is made, below retains the thick copper product of 0.3-0.5mm and forms layers of copper 3, the physical characteristic utilizing copper plasticity good with this ensures the sealing between spark plug lining and cylinder head.
Spark plug lining of the present utility model is through experimental verification, and sealing works very well, assembles rear water-tight, air tight with cylinder head, and overall low cost of manufacture.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
Claims (3)
