Abstract
The utility model discloses a kind of cylinder block sub-assemblies, include starter mounting hole and starter mounting surface, the starter mounting hole avoids technique groove in the knife bar close to the oriented starter mounting screw through-hole direction protrusion in the position of starter mounting screw through-hole.The starter mounting surface of the utility model may be used "T"-shaped knife and be processed, and the technological equipment that can be obtained very high processing efficiency, and use is then common cutter, greatly reduces the cost of charp tool and processing cost.
Description
Technical field
The utility model is related to a kind of component of engine, especially a kind of cylinder block sub-assembly of automobile engine.
Background technology
Starter mounting hole and face are provided on the cylinder block sub-assembly of engine, mounting surface is the face parallel with rear end face,
Positioned at the back side of aft end flange, starter mounting surface has to be machined out, parallel between flatness and face to ensure
Degree.Starter mounting surface is one and is similar to round plane, and circle and the starter mounting hole decentraction of starter mounting surface are rising
The periphery processing capacity of motivation mounting hole is simultaneously unequal, thus its processing is quite inconvenient, is particularly away from the portion of starter mounting hole
Position, it is in irregular shape.Processing currently for starter mounting surface is placed downwards using cylinder body bottom surface, using 90 ° of angle
Head is processed from side feed；The program needs dedicated angle head, the cost of charp tool higher；And it has to large-scale lathe
It can processing.
Purpose of the utility model is to solve deficiencies in the prior art, provide a kind of cylinder block portion of engine
Part, starter mounting surface are easy to process.
Invention content
In order to achieve the above object, the solution of the utility model is：A kind of cylinder block sub-assembly includes starter peace
Hole and starter mounting surface are filled, the starter mounting hole is located at the rear end of cylinder block sub-assembly, the starter mounting surface
The back side positioned at the rear end of cylinder block sub-assembly, there are two starter mounting screw through-hole on the starter mounting surface, two
Starter mounting screw through-hole is distributed in the upper and lower sides of the starter mounting hole；It is characterized in that：The starter peace
It fills hole and avoids work in the knife bar close to the oriented starter mounting screw through-hole direction protrusion in the position of starter mounting screw through-hole
Skill groove.
Further, foregoing cylinder block sub-assembly, it is characterised in that：The starter mounting surface and upside with
There is an inclined groove in the main part junction of cylinder block sub-assembly, the starter mounting surface and lower edge have it is horizontal
Groove.
The utility model in terms of existing technologies, has the following advantages：On the starter mounting hole of the utility model
To starter mounting screw through-hole direction protrude knife bar avoid technique groove, during processing, may be used "T"-shaped knife into
Row processing, when "T"-shaped knife enters groove location, can be worked into the outer ledge of starter mounting surface, starter mounting surface
Rest part ensure that starter is equipped with enough contact surfaces.It is processed using "T"-shaped knife, very high processing can be obtained
Efficiency, and the technological equipment used is then common cutter, greatly reduces the cost of charp tool and processing cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further described with embodiment below in conjunction with the accompanying drawings
As shown in Figure 1, a kind of cylinder block sub-assembly 1, includes starter mounting hole 3 and starter mounting surface 4, described rises
Motivation mounting hole 3 is located at the rear end face 2 of cylinder block sub-assembly, and the starter mounting surface 4 is located at the rear end of cylinder block sub-assembly 1
The back side, there are two starter mounting screw through-holes 5, two starter mounting screw through-holes 5 to divide on the starter mounting surface 4
Upper and lower sides of the cloth in the starter mounting hole 3；It is characterized in that：The starter mounting hole 3 is pacified close to starter
The knife bar evacuation technique groove 6 of oriented 5 direction of the starter mounting screw through-hole protrusion in position of cartridge screw through-hole 5.
The knife bar evacuation technique groove 6 is arc-shaped, and arc diameter is more than straight for the knife bar of the T shape knives of processing
Diameter；Center of arc position offsets out the endpoint come in 4 inner arc of starter mounting surface to 3 direction of starter mounting hole
On.
There is inclined groove 7 in the main part junction of the starter mounting surface 4 and cylinder block sub-assembly 1, and described inclines
Oblique groove is arc-shaped；It is circular arc that the lower edge of the starter mounting surface, which has horizontal groove 8, the horizontal groove,
Shape.The recessed step surface 9 in 2 direction of rear end face of the oriented cylinder block sub-assembly of outer side edges of starter mounting surface 4.Starter mounting surface
4 upper side has inclined groove 7, which may be used milling cutter and be processed from side, the downside of starter mounting surface
There is horizontal groove 8 in face, which may be used milling cutter and be processed from side, ensure that starter installation when and cylinder
Body component 1 does not have interference, while having enough contact surfaces.
The part of the utility model during processing, may be used "T"-shaped knife and be processed, the cross of the T shape knives
There are blade, the front cutting edge of "T"-shaped knife to carry out the Boring of starter mounting hole to portion front and back end, boring continues traveling downwardly after wearing,
The processing for carrying out starter mounting surface with the rear knife edge of "T"-shaped knife again, makees circular motion in the horizontal plane, and "T"-shaped knife enters recessed
When groove location, it can be worked into the outer ledge of starter mounting surface, to ensure the flatness of starter mounting surface.
The cylinder block sub-assembly of the utility model has opened up knife bar evacuation groove on starter mounting hole, may be used " T "
Shape knife reduces the requirement to technological equipment into the processing of start of line machine side, while having very high processing efficiency, greatly reduces
Equipment investment, the cost of charp tool and processing cost.
