Description
Technical field
The present invention relates to engine assembly manufacturing technology field, in particular to a kind of high accuracy install pore structure.
Background technique
In engine assembly manufacturing field, engine cylinder block or cylinder head etc. need to assemble other precision components or need
The part of cooperation sealing, such as cylinder block lubricating oil pump mounting hole or idle gear shaft mounting hole etc., aperture are carried out with installation part
It is lubricating oil pump mounting hole to face, same lubricating oil pump is needed to have degree of precision cooperation, hole bottom surface is sealing surface, needs to seal high-pressure oil
Therefore empty bottom surface needs to form sealing with lubricating oil pump, and there are the processing request of degree of precision in the sagittal plane in hole and bottom surface.It is processing
When be difficult to guarantee the precision of hole bottom surface and hole sagittal plane simultaneously because two faces are that separate machined forms, it is difficult to guarantee verticality
It is required with roughness etc..Such as Chinese patent CN107780992A, the lubricating oil pump oil-returning structure of disclosed engine is mentioned in the structure
And to lubricating oil pump mounting groove is integrated in the cylinder block, the lubricating oil pump is installed in the lubricating oil pump mounting groove, machine oil
The sealing bottom surface face and mounting surface for pumping mounting groove are directly to contact, and are difficult to guarantee simultaneously hole bottom surface and hole sagittal plane when processing
Precision, it is difficult to guarantee the requirement such as verticality and roughness.
In the prior art, it in lubricating oil pump structure of mounting hole, due to lubricating oil pump sealing surface while needing to be formed with lubricating oil pump close
The envelope band sealing up to high-pressure oil of 0.8MPa, therefore the roughness of lubricating oil pump sealing surface, flatness and lubricating oil pump mounting surface
Relative tolerance, such as verticality require to have higher requirements, and basically two faces are to be obtained respectively with different processes, at present also
There is equipment that can guarantee the process equipment in two faces simultaneously.Traditional way is, according to shown in Fig. 1, in the position of two faces handover
Do a R1 fillet.Or doing a height as shown in Figure 2 is H, angle is the oblique angle of θ to connect two faces, but no matter is adopted
Which kind of structure all can form the handover trace of uncertain height in two faces with, if will lead on band it is poorly sealed, such as
Fruit will lead to lubricating oil pump assembly difficulty or stuck on sagittal plane, it is therefore desirable to the height of control handover trace.
Summary of the invention
The present invention provides a kind of high accuracy install pore structure, sagittal plane and the separation of bottom hole face interval, and when processing was both able to satisfy
The required precision of sagittal plane and hole bottom surface, and it is avoided that the processing residual handover trace in two faces influences assembly.
Technical scheme is as follows: a kind of high accuracy install pore structure, is arranged in cylinder block, for installing cylinder
Shape component, the mounting surface including with cylindrical parts outer ring surface cooperation being in internal spherical surface structure, positioned at the inner end of mounting surface
The sealing plane of side, the sealing plane is for sealing the front end for cooperating the cylindrical parts, the mounting surface inner side edge
Edge is provided with the first chamfering, and the sealing plane edge is provided with the second chamfering, and first chamfering and second chamfering connect
It connects, first chamfering and second chamfering junction are in shoulder structure.
The present invention will use a shoulder to separate between the mounting surface and the sealing plane, i.e., the described first chamfering institute
The second chamfering is stated in ladder, forms a shoulder, the mounting surface and the sealing plane are separately positioned, add respectively respective
Work bottom surface processes the first chamfering and the second chamfering, can control the range of respective processing handover trace and the depth of control handover trace respectively
Degree；
It realizes the mounting surface and the sealing plane and processes respectively and guarantee to be unlikely to make to hand over again while relative accuracy
The function of lapping defect influence lubricating oil pump.Handover trace after being processed respectively due to the mounting surface and the sealing plane is distinguished
It is under control, is not in the case where handover trace influences each other, the processing of the mounting surface and the sealing plane is not mutual
It influences, therefore, not only can guarantee that the outer ring surface mounting position degree of cylindrical parts was accurate, but also can guarantee the processing essence of sealing plane
Degree, avoiding the occurrence of bottom surface can not seal or the problem of sagittal plane can not assemble.
Preferably, the high accuracy install pore structure further includes between first chamfering and second chamfering
Third chamfering, the third chamfering is more than one, one or more shoulders can be formed, so that the mounting surface and described close
The distance for sealing plane is farther, preferably controls the handover trace height of the interface of the mounting surface and the sealing plane.
Preferably, first chamfering is one of fillet or oblique angle, and second chamfering is in fillet or oblique angle
One kind, using structure easy to process, the processing is simple, at low cost.
Preferably, the front end of the cylindrical parts is provided with lead-in angle.Cylindrical parts front end lead-in angle, the importing
The shoulder that angle can avoid first chamfering and second chamfering structure is formed, avoids the generation of interference, makes cylinder
Component is not in the phenomenon that withstanding the high accuracy install pore structure, to be easily installed simultaneously.
Preferably, the cylindrical parts are lubricating oil pump, after lubricating oil pump is packed into the high accuracy install pore structure, Ji Yaobao
The position degree for demonstrate,proving lubricating oil pump is accurate, prevents oil pump gear and its meshed gears gear clearance are excessive to generate larger make an uproar again
Sound, while the radial accuracy of lubricating oil pump mounting hole, such as roughness, verticality, cylindricity, position degree, all have higher requirements, no
So be difficult to ensure that lubricating oil pump assembles demand, therefore lubricating oil pump is highly suitable for the high accuracy install pore structure, installation effect compared with
It is good.
Preferably, the high accuracy install pore structure, which is integrally formed, is arranged in cylinder block, and structure is simple, directly in cylinder
The structure is processed on body, saves installation steps, and structural strength is preferable, compact-sized.
The beneficial effects of the present invention are:
1, the present invention will be separated between the mounting surface and the sealing plane using shoulder, can control respective add respectively
The range of industry and traffic lapping defect and the depth of control handover trace, not only can guarantee that the outer ring surface mounting position degree of cylindrical parts was accurate, but also
Can guarantee that the machining accuracy of sealing plane, two face relative accuracys are also guaranteed, avoid the occurrence of bottom surface can not seal or
The problem of sagittal plane can not assemble.
2, the present invention will be separated between the mounting surface and the sealing plane using shoulder, is not directly connected, the peace
Behind dress face and the sealing plane separate machined, without considering further that the height of handover trace of the two controls, processing efficiency is improved.
3, structure is simple, and first chamfering and second chamfering are fillet or oblique angle structure, can form machine table
Shoulder, the processing is simple, at low cost.
