As shown in Figure 1 to Figure 3, split type two cylinder head side by side of diesel engine need to clamp installation by cylinder head bolt and cylinder block simultaneously.Existing mounting structure is: first, the end face of a cylinder head 11 offers long semicircle orifice 12 and groove 13 wherein, and long semicircle orifice 22 and groove 23 are set at the end face of another cylinder head 21, be pressed on spherical washer 32 by bolt 31 again, spherical washer 32 is pressed on the conical surface of taper faced washer 33, taper faced washer 33 is pressed in cylinder head 11,21 simultaneously, and bolt 31, through the long semicircle orifice of spherical washer 32, taper faced washer 33 and mutual disjunct cylinder head 11,21, is screwed in the screw 35 of cylinder block 34.
Spherical washer 32 and the taper faced washer 33 of this mounting structure are linear contact lay, structural rigidity spherical washer and taper faced washer being mated coordinate when pretightening force is very large is not enough, support to bolt 31 reliably, when whole fastening system bears the dynamic load along bolt 31 axial direction, bolt 31 is easily loose, finally causes Joint failure.
In addition, the mistake nail of cylinder head 11,21 is long semicircle orifice, and end face fluting, this structure causes the rigidity of support below the corresponding bolt 31 of cylinder head 11,21 poor, support cannot to equally bolt 31 reliably, have impact on the connection reliability of whole fastening system.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of simple and reasonable cylinder head bolt clamping arrangement, this cylinder head bolt clamping arrangement coordinates with the inclined-plane of cylinder head by spherical washer and the linear contact lay of taper faced washer are improved to clamp, improves the rigidity of this clamping arrangement and the connection reliability of whole fastening system.In addition, the long semicircle orifice of original cylinder head is improved to semicircle orifice by this cylinder head bolt clamping arrangement, and eliminates end face fluting, further enhancing the rigidity of connected piece (cylinder head), makes whole fastening system become reliable.
For achieving the above object, the invention provides cylinder head bolt clamping arrangement, it is for fixedly mounting split type the first cylinder head of being arranged side by side and the second cylinder head and cylinder block, this cylinder head bolt clamping arrangement comprises: cylinder head bolt and clamp, first cylinder head and the second cylinder head are corresponding respectively offers the first formation hole, the second formation hole that cylinder head bolt crosses nail, and the end face of the first cylinder head and the second cylinder head is formed with the first inclined-plane, the second inclined-plane respectively; The bottom of clamp is formed and the first cylinder head and the first inclined-plane of the second top surface of cylinder cover, the 3rd inclined-plane of the second inclined-plane adaptation.
Preferably, in technique scheme, the end face of the first cylinder head and the second cylinder head is formed respectively and forms along described first outward extending first inclined-plane of ora terminalis, the second inclined-plane that hole, second forms hole.
Preferably, in technique scheme, first forms hole and the second formation hole is semicircle orifice.
Compared with prior art, the present invention has following beneficial effect: this cylinder head bolt clamping arrangement coordinates with the inclined-plane of cylinder head by spherical washer and the linear contact lay of taper faced washer are improved to clamp, improves the rigidity of this clamping arrangement and the connection reliability of whole fastening system.In addition, the long semicircle orifice of original cylinder head is improved to semicircle orifice by this cylinder head bolt clamping arrangement, and eliminates end face fluting, further enhancing the rigidity of connected piece (cylinder head), makes whole fastening system become reliable.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 4 to 6, be used for split type the first cylinder head 41 of being arranged side by side and the second cylinder head 51 to fixedly mount with cylinder block 61 according to the cylinder head bolt clamping arrangement of the specific embodiment of the invention, its concrete structure comprises: cylinder head bolt 62 and clamp 63, wherein, cylinder head bolt 62 is through the mistake nail of clamp 63 and disjunct first cylinder head 41 and the second cylinder head 51 mutually, be screwed in the screw 64 of cylinder block 61, and then the first cylinder head 41 and the second cylinder head 51 are fixed in cylinder block 61.
Wherein, the first cylinder head 41 and the second cylinder head 51 respectively correspondence offer semicircle orifice 42,52, and the circle that semicircle orifice 42,52 forms the first cylinder head 41 and the second cylinder head 51 relatively crosses nail, for wearing cylinder head bolt 62.The end face of the first cylinder head 41 and the second cylinder head 51 is formed with the outward extending inclined-plane 43,53 of ora terminalis along semicircle orifice 42,52 respectively.
The bottom of clamp 63 is formed with the inclined-plane 65 with inclined-plane 43,53 adaptation of the first cylinder head 41 and the second cylinder head 51 end face, cylinder head bolt 62 through clamp 63 and mutually disjunct first cylinder head 41 and the second cylinder head 51 mistake nail and in the screw 64 being screwed into cylinder block 61 time, the inclined-plane 65 of clamp 63 contacts with inclined-plane 43,53 forming surface of the second cylinder head 51 end face with the first cylinder head 41, further increases the rigidity of this clamping arrangement and the connection reliability of whole fastening system.
To sum up, this cylinder head bolt clamping arrangement coordinates with the inclined-plane of cylinder head by spherical washer and the linear contact lay of taper faced washer are improved to clamp, improves the rigidity of this clamping arrangement and the connection reliability of whole fastening system.In addition, the long semicircle orifice of original cylinder head is improved to semicircle orifice by this cylinder head bolt clamping arrangement, and eliminates end face fluting, further enhancing the rigidity of connected piece (cylinder head), makes whole fastening system become reliable.
