Abstract
The utility model discloses a cylinder cover screw bolt fastening structure, which comprises a cylinder cover screw bolt and a screw bolt gasket. The screw bolt gasket supports the cylinder cover screw bolt, a cylinder cover is provided with an overhead camshaft mounting hole, a cylinder cover screw bolt mounting stepped hole is arranged below the camshaft mounting hole, and the cylinder cover screw bolt mounting stepped hole and the camshaft mounting hole are perpendicularly arranged. The cylinder cover screw bolt is mounted inside the cylinder cover screw bolt mounting stepped hole; after mounting, the head portion of the screw bolt is sunk into the stepped hole; the mounting height of the cylinder cover screw bolt is lower than the camshaft mounting hole. The cylinder cover screw bolt fastening structure has the advantages of optimizing arrangement space of the top surface of the cylinder cover, being favorable for the arrangement of an engine air distribution system, having simplestructure, low manufacturing cost and being widely applied to various overhead camshaft engines.
Description
Technical field
The utility model relates to a kind of bolt fastening structure, specifically, relates to a kind of cylinder head bolt fastening structure.
Background technique
The cylinder head bolt majority of overhead camshaft engine is arranged apart with the camshaft mounting hole at present, in the space of cylinder head end face, also need to arrange distribution device, lubricating oil path, gas channel even also want arranging exhaust air braking system, oil sprayer wire harness etc. that cylinder head bolt end face space is very limited.The present cylinder head bolt hole and the arrangement of camshaft mounting hole take up room bigger, are unfavorable for the layout of other mechanism of cylinder head end face.
The model utility content
The utility model technical issues that need to address are to overcome the defective of prior art, a kind of cylinder head bolt fastening structure is provided, cylinder head bolt mounting hole and camshaft mounting hole are arranged vertically, and can effectively optimize the space of other system layouts such as cylinder head end face distribution device.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of cylinder head bolt fastening structure of the utility model, comprise cylinder head bolt and bolt pad, the bolt pad supports cylinder head bolt, cylinder head is provided with the overhead camshaft mounting hole, camshaft mounting hole below is provided with cylinder head bolt shoulder hole is installed, and cylinder head bolt is installed shoulder hole and is provided with the camshaft mounting hole is vertical, and cylinder head bolt is installed in cylinder head bolt and installs in the shoulder hole, the described bolt head in back is installed is sunk in the shoulder hole, its setting height(from bottom) is lower than described camshaft mounting hole.
In the technique scheme, each cylinder both sides is equipped with camshaft and supports shelves, and described cylinder head bolt is installed shoulder hole and is arranged on the camshaft support shelves, and is positioned at the below of camshaft mounting hole.
Cylinder head bolt fastening structure of the present utility model can be optimized the arrangement space of cylinder head end face, helps the layout of systems such as engines distribution, and simple in structure, easy to process, low cost of manufacture.Can be widely used on the various cammers.

Fig. 2 is the sectional view of the utility model cylinder head bolt fastening structure;
Fig. 3 is the shaft side figure of the utility model cylinder head bolt fastening structure.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-camshaft supports shelves, 2-camshaft mounting hole; The 3-cylinder head bolt is installed shoulder hole; The 4-cylinder head bolt; 5-bolt pad; The 6-cylinder head.
Embodiment
As Figure 1-3, cylinder head bolt fastening structure of the present utility model is used for fixing cylinder head 6, comprises cylinder head bolt 4 and bolt pad 5, and bolt pad 5 is used to support cylinder head bolt 4.The every cylinder of cylinder head both sides are equipped with camshaft and support shelves 1, camshaft supports shelves 1 and is provided with overhead camshaft mounting hole 2, camshaft mounting hole below is provided with cylinder head bolt shoulder hole 3 is installed, cylinder head bolt is installed shoulder hole 3 and the 2 vertical settings of camshaft mounting hole, cylinder head bolt 4 is installed in cylinder head bolt and installs in the shoulder hole 3, the back bolt head is installed is sunk in the shoulder hole 3, do not protrude camshaft mounting hole 2 (being that the bolt setting height(from bottom) is lower than camshaft mounting hole 2).Cylinder head bolt is installed shoulder hole 3 and is arranged in camshaft and supports on the shelves, and be positioned at camshaft mounting hole 2 below.After cylinder head bolt 4 and bolt pad 5 were installed, bolt head sank to cylinder head bolt fully and installs in the shoulder hole 3, can not produce with camshaft or camshaft bush and interfere.
The installation process of cylinder head bolt fastening structure of the present utility model and dependency structure is as follows: as shown in Figure 2, at first cylinder head 6 is installed on the cylinder block, cylinder head bolt 4 and bolt pad 5 are installed, and by the technological requirement make-up torque, and then camshaft bush is installed in the camshaft mounting hole, or camshaft is installed directly.
Cylinder head bolt fastening structure of the present utility model makes cylinder head bolt mounting hole and camshaft mounting hole be arranged vertically, and the bolt after installing can not produce with camshaft or camshaft bush interferes, and can optimize the space of other system layouts such as cylinder head end face distribution device.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
