Abstract
The utility model discloses an aluminium engine body, which includes a main body and an outer cover, wherein a plurality of threaded holes are arranged on the end surface of the main body. The aluminium engine body is characterized in that stainless steel cylindrical sleeves with external threads are screwed in the threaded holes. As the stainless steel cylindrical sleeves has high hardness, strength and abrasion resistance, during the actual use, possibility of abrading the internal threads of the stainless steel cylindrical sleeves is low, so that the connecting reliability of the main body and the outer cover is greatly improved. The aluminium engine body belongs to the technical field of automobile parts.
Description
Technical field
The utility model belongs to the auto parts machinery technical field, especially relates to a kind of aluminium engine body.
Background technique
In order to alleviate the automobile overall weight, the most of aluminium material that adopts of existing automobile engine body is made, and mainly comprises body and enclosing cover, and the body end face is provided with a plurality of tapped holes, links to each other with enclosing cover through bolt.It is not enough below the aluminium engine body of said structure exists; Because aluminium material is more broken, wear-resisting property is relatively poor, and body and enclosing cover are after bolt has cooperated often; Tapped hole on the body and the bolt place of matching take place loosening; And the screw thread in the tapped hole is prone to polished, and it is insecure to cause bolt to be connected with tapped hole, causes enclosing cover to be connected weak effect with body.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of body end face tapped hole internal thread nonabradable aluminium engine body.
The technological scheme that the utility model is taked is: a kind of aluminium engine body, comprise body and enclosing cover, and the body end face is provided with a plurality of tapped holes, is combined with the stainless steel cylindrical sleeve of band internal and external threads in the tapped hole.
The beneficial effect of the utility model is: the stainless steel cylindrical sleeve that is combined with the band internal and external threads in the tapped hole of the utility model aluminium engine body body end face; Through the stainless steel cylindrical sleeve with outside the bolt that covers link to each other because stainless steel hardness is big, intensity is high; Wear-resisting property is good; Therefore in the middle of actual the use, the stainless steel internal thread is not easy to wear, has improved the reliability that is connected of body with enclosing cover widely.
Description of drawings
Fig. 1 is the utility model body plan view.
Fig. 2 is the utility model stainless steel sleeve plan view.
Among the figure, 1, body, 1.1, tapped hole, 2, the stainless steel cylindrical sleeve.
Embodiment
Below be the utility model preferred embodiment, but therefore do not limit the protection domain of the utility model.
Shown in seeing figures.1.and.2, a kind of aluminium engine body of the utility model comprises body 1 and enclosing cover, and body 1 end face is provided with a plurality of tapped holes 1.1, is combined with the stainless steel cylindrical sleeve 2 of band internal and external threads in the tapped hole 1.1.
Be combined with the stainless steel cylindrical sleeve 2 of band internal and external threads in the tapped hole of the utility model aluminium engine body body end face; Promptly the external thread rotary through stainless steel cylindrical sleeve 2 is combined in the tapped hole 1.1 of body 1; When enclosing cover and body 1 cover after bolt screws in the endoporus of stainless steel cylindrical sleeve 2, body 1 and enclosing cover are linked into an integrated entity.
Because it is big that stainless steel cylindrical sleeve 2 is compared aluminium hardness, intensity is high, and wear-resisting property is good, and in the middle of therefore actual the use, the internal thread of stainless steel cylindrical sleeve 2 is not easy to wear, has improved the be connected reliability of body 1 with enclosing cover widely.
The utility model is the same with the engine body working principle of existing technology, repeats no more here.
Claims (1)
