Description
Technical field
It the utility model is related to Crankshaft Machining technical field, and in particular to one kind processing special sand of automobile engine crankshaft
Wheel.
Background technology
In the process of engine crankshaft, after thick, finishing processing is carried out to the trunnion of bent axle and rod journal,
Often also need to polish to it, make its any surface finish, smooth.So as to ensure the dynamic balancing of bent axle and reduce rod journal with
Frictional force when connecting rod connects.Effect of the abrasive particle to workpiece includes swiping, delineation and cutting, and most of mills during grinding
Grain is negative rake and small relief angle, so in whole grinding process, can produce substantial amounts of grinding heat, make the transient temperature of grinding area
Up to 1000 DEG C or so.So high temperature can make the metallographic structure of workpiece surface layer change, and cause grinding burn.Grinding
Burn can destroy the metallographic structure of crankshaft thrust face top layer, reduce coating metal intensity and hardness, and be produced with residual stress,
Even there is microfissure, and deteriorate workpiece surface quality, have a strong impact on the wearability and service life of crankshaft thrust face.This
Kind grinding burn can not remove in abrasive band polishing, it is therefore necessary to avoid grinding burn.Meanwhile during grinding along with
Substantial amounts of chip produces, and substantial amounts of fine grained chip will cause tremendous influence to the environment of workshop.
The content of the invention
The purpose of this utility model is to be directed to above technical problem, there is provided one kind processing special sand of automobile engine crankshaft
Wheel, can effectively be controlled the temperature of Working position, while is had to machining chips and collected function.
To achieve the above object, the technical solution adopted in the utility model is：One kind processing automobile engine crankshaft is special
Emery wheel, including the metallic matrix positioned at center and the emery wheel main body positioned at metallic matrix periphery.Set and wear on the metallic matrix
Shaft through-hole and multiple bolts hole, the center worn shaft through-hole and be located at metallic matrix, the bolt hole is centered on wearing shaft through-hole
It is uniformly distributed in a ring.
The groove of one ring shape is set on the side face of the emery wheel main body along side face, and the two sides of emery wheel main body are set respectively
The gib block of more arcs, the gib block is radial centered on metallic matrix to be uniformly distributed.The thickness of the emery wheel main body
Degree from side face to gradually increasing at center.Scrap collecting passage is formed between adjacent two gib block.
Preferably, the metallic matrix is aluminum substrate.
Preferably, the groove is located at the center of emery wheel body peripheral face.
The utility model has the advantages that：
1. the utility model is when in use, is connected by the rotating shaft for wearing shaft through-hole and bolt hole and grinding machine, utilize emery wheel master
The week of body is polished in face of the axle journal of bent axle, during polishing can into groove spray water or other coolants, avoid
Occur the state dry grinded during polishing, be easy to the control to workpiece temperature, improve the effect of processing.
2. forming scrap collecting passage between two adjacent gib blocks of the utility model, scrap collecting passage is close to emery wheel
The one end open of body peripheral face is big, and another end opening is small, and during emery wheel body rotation, scrap collecting access portal is big
Chip can be caught and be oriented to chip to the small one end of opening by one end.
3. the thickness of the utility model emery wheel main body is to gradually increasing at center, on the one hand compensate for due to recessed at side face
The deficiency of structural strength, on the other hand easily facilitates one of chip from scrap collecting passage close to metallic matrix caused by groove is set
End convergence discharge, it is only necessary to which water spray is oriented to metallic matrix can reduce dust, very easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 right view；
Fig. 3 is the G-G direction views of structure shown in Fig. 1.
Embodiment
A kind of processing automobile engine crankshaft special grinding wheel with reference to shown in Fig. 1-3, as shown in figure 1, including being located at center
Metallic matrix 1 and the emery wheel main body 2 positioned at the periphery of metallic matrix 1.Metallic matrix 1 of the present utility model can be aluminum substrate,
Alloy matrix aluminum etc..Set on the metallic matrix 1 and wear shaft through-hole 3 and multiple bolts hole 4, it is described to wear shaft through-hole 3 and bolt hole 4
It is used to be connected with grinding machine.The center worn shaft through-hole 3 and be located at metallic matrix 1, during the bolt hole 4 is to wear shaft through-hole 3
The heart is uniformly distributed in a ring.
The groove 5 of one ring shape is set on the side face of the emery wheel main body 2 along side face, and the depth of the groove 5 generally exists
Between 2-15mm, certainly, according to the actual size of emery wheel main body 2, it can also adjust accordingly.The groove 5 is normally at
The center of the side face of emery wheel main body 2.As shown in Fig. 2 namely the center of the side face of emery wheel main body 2 is divided into two parts by groove 5,
So easily facilitate the position of control polishing.The two sides of emery wheel main body 2 set the gib block 6 of more arcs respectively, are led in Fig. 1
It it is 8 to the quantity of bar 6,8 gib blocks 6 are radial centered on metallic matrix 1 to be uniformly distributed.The emery wheel main body 2
Thickness is to gradually increasing at center, that is, the thickness of emery wheel main body 2 is gradually thickening from outer rim to inner edge at side face.Adjacent two
Scrap collecting passage 7 is formed between gib block 6, that is to say, that also there are 8 scrap collectings in Fig. 1 to 7.It should be noted that
The utility model is arranged on when on grinding machine, it is necessary to keep the direction of larger one end of opening of scrap collecting passage 7 to turn with grinding machine
The rotation direction of axle is consistent, that is, the utility model rotates in the direction of the clock in Fig. 1.
The utility model when in use, is connected with the rotating shaft of grinding machine by wearing shaft through-hole 3 and bolt hole 4, utilizes emery wheel master
The week of body 2 is polished in face of the axle journal of bent axle, during polishing can into groove 5 spray water or other coolants, avoid
There is the state dry grinded in polishing, be easy to the control to workpiece temperature, improve the effect of processing.Two adjacent gib blocks
Scrap collecting passage 7 is formed between 6, scrap collecting passage 7 is big close to the one end open of the side face of emery wheel main body 2, another end opening
Small, during emery wheel main body 2 rotates, the big one end that is open of scrap collecting passage 7 can catch chip and by chip to opening
The small one end of mouth is oriented to.Meanwhile the thickness of emery wheel main body 2 to gradually increasing at center, on the one hand compensate at side face due to
The deficiency of structural strength, on the other hand easily facilitates chip from scrap collecting passage 7 close to metallic matrix caused by groove 5 is set
1 one end convergence discharge, it is only necessary to which water spray is oriented to metallic matrix 1 can reduce dust, very easy to use.
