Description
Technical field
The utility model relates to engine art, particularly a kind of loss of weight cylinder block of diesel engine.
Background technique
The cylinder block of motor generally passes through casting, for traditional cylinder block, as shown in Figures 1 to 4, for convenience of model, Design of Dies, the front-end face 10 of cylinder block, ear end face 30, bottom surface 50 and bearing support bi-side 60 custom make a large processing plane, and the suppending hole system of left side 20, right side 40 also connects into a processing plane.
For above-mentioned cylinder block, its front-end face 10, ear end face 30, bottom surface 50 and bearing support bi-side 60 are unnecessary makes large processing plane, in fact, only need to ensure that sealing surface (part faying surface) is that a plane is just enough, the waste that working surface can cause blank material, processing is made in unwanted regions outside sealing surface, and finished weight is also heavier.And the suppending hole system of left side 20, right side 40 also connects into a processing plane, there is the waste of material and processing, the increase of pts wt in design that neither be completely necessary equally.In addition, left side 20, the right side 40 of cylinder block are not designed with cylinder holes conformal, and between cylinder, material local accumulation also causes waste, and this also makes cylinder block overweight, and manufacturing process performance is also poor.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, 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.
Model utility content
The purpose of this utility model is the loss of weight cylinder block providing a kind of diesel engine, process by only installing faying surface to the part of the front-end face of cylinder block, ear end face and bottom surface, other inessential machining areas are recessed installs faying surface in part, make the weight saving of cylinder block, reduce amount of finish, cost-saving, raise the efficiency.
For achieving the above object, the utility model provides a kind of loss of weight cylinder block of diesel engine, comprise: leading flank, trailing flank and bottom side, leading flank, trailing flank and bottom side have part and install faying surface, other regions leading flank, trailing flank and bottom side removing part installation faying surface are recessed in part installation faying surface; And left surface and right flank, left surface and right flank have suppending hole system, and the hole wall of suppending hole system is linked together by stiffening rib.
Preferably, also comprise bearing support bi-side, these bearing support bi-side are hollowed out.
Preferably, suppending hole cording has attachment face, and other regions and the cylinder holes conformal that left surface and right flank remove attachment face are arranged.
Compared with prior art, the utility model has following beneficial effect: installing faying surface (sealing surface) by the part of the leading flank of only retained gas cylinder body, trailing flank and bottom side is processing plane, non-working surface is made in region outside sealing surface, adopt stiffening rib to be connected with the suppending hole system of right flank cylinder block left surface simultaneously, and left surface and right flank adopt and design with cylinder holes conformal, between cylinder, material does not have local accumulation, greatly alleviate blank, finished weight, reduce amount of finish, save material, provide the manufacturing process performance of cylinder block.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model 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 Fig. 5 to Fig. 8, according to the loss of weight cylinder block of a kind of diesel engine of the utility model embodiment, comprise leading flank 1, trailing flank 3, left surface 2, right flank 4 and bottom side 5, wherein at leading flank 1, trailing flank 3 and bottom side 5 has part installation faying surface (unmarked in figure), at leading flank 1, trailing flank 3 and bottom side 5 remove part and install that other regions of faying surface are recessed installs faying surface in part, as long as namely ensure that installing faying surface to part processes, when the Design of Dies of cylinder block casting, other regions are recessed becomes inessential machining area in these parts installation faying surface, the region of these depressions needs the wall thickness ensureing about 5mm, certainly, regional area can add stiffening rib 7, the intensity of whole cylinder block is not reduced.For the suppending hole system that left surface 2 and right flank 4 have, suppending hole cording is guaranteed has attachment face, other regions and the cylinder holes conformal that left surface 2 and right flank 4 remove attachment face are arranged (part being labeled as A in figure), and the hole wall of suppending hole system can be linked together by stiffening rib 8.
In addition, for the bearing support bi-side 6 of cylinder block, it carries out local according to CAE intensive analysis and hollows out, and then reaches the object of loss of weight.
In a word, as long as this loss of weight cylinder block ensures at leading flank 1, faying surface (sealing surface) installed by the part of trailing flank 3 and bottom side 5 is that a plane is just enough, non-working surface is made in region outside sealing surface, cancel original cylinder block left surface 2 simultaneously, the processing plane that the suppending hole system of right flank 4 connects into, change the hole wall that stiffening rib connects suppending hole system into, and left surface 2 and right flank 4 adopt and design with cylinder holes conformal, between cylinder, material does not have local accumulation, in addition local is carried out to bearing support bi-side 6 and hollow out design, greatly alleviate blank, finished weight, reduce amount of finish, save material, the manufacturing process performance of cylinder block is provided.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
