Description
Technical field
The utility model belongs to the machining tool field of " C " type stop block structure automobile hub unit inner flange, more particularly to
A kind of compound emery wheel of automobile hub unit inner flange.
Background technology
The automobile hub unit category third generation product of " C " type stop block structure, inner flange and existing for processing inner flange
Grinding wheel it is as shown in Fig. 3, grinding wheel is modified using integral type machine-shaping and using emery wheel, to inner flange work
When part is processed, inner flange workpiece tilts 5 to 15 degree beats, and grinding wheel high-speed rotation is ground inner flange.Though existing grinding wheel
It can so accomplish that high-precision is processed to inner flange, but since during grinding, some grain abrasives in grinding wheel can fall off
And cut with metal and to form cutting mud, cutting mud is stained in the grinding surface of grinding wheel, and abrasive grain cannot be cut liquid band and walk and can scratch in time
Inner flange simultaneously reduces machining accuracy, causes the fraction defective of inner flange high.
Therefore, existing grinding wheel has the shortcomings that fraction defective is high for inner flange processing.
Utility model content
The purpose of the utility model is to provide a kind of compound emery wheels of automobile hub unit inner flange.The utility model is used
Have the advantages that fraction defective is low in inner flange processing.
The technical solution of the utility model：A kind of compound emery wheel of automobile hub unit inner flange, including ontology, ontology are axial
It is equipped with fixed hole, the side of fixed hole is equipped with the water channel through ontology, and water channel is the axis of arc and middle part close to ontology
The peripheral surface of line, ontology is equipped with rhone, and the bottom of rhone is equipped with multiple osculums being connected to water channel.
In the compound emery wheel of automobile hub unit inner flange above-mentioned, the side wall of the rhone is equipped with outward oblique
Degree.
In the compound emery wheel of automobile hub unit inner flange above-mentioned, the quantity of the rhone has three, circumferential uniform point
Cloth is on the peripheral surface of ontology.
In the compound emery wheel of automobile hub unit inner flange above-mentioned, the diameter that the diameter at the water channel both ends is big, intermediate is small,
The osculum is speaker hole, and the big end of osculum is connect with water channel.
Compared with prior art, when the utility model is processed for inner flange, a cutting mud part is arranged from rhone both ends
Go out, another part is discharged from osculum through water channel in time, and to the abrasion of inner flange and processing is improved so as to avoid cutting mud
Precision.Since water channel is arc and middle part close to ontology, it is located at the cutting mud at water channel both ends under the influence of centrifugal force to acceleration
It discharges, cutting mud can be effectively prevent to be blocked in inside water channel.
Further, the side wall of rhone is equipped with outward gradient, and the utility model squeezes grinding inner flange
When, the cutting mud in rhone can be extruded the high pressure to be formed into osculum, and cutting mud more easily enters draining
Hole, reducing inner flange surface tear caused by cutting mud escapes and machining accuracy reduces.By limit rhone quantity and
Arrangement mode ensure that the dynamic balancing of grinding wheel, in turn ensure the quick discharge of cutting mud.It is special due to water channel and osculum
Shape, when cutting mud and blocking water channel and osculum, worker, which can be relatively easy to, to unclog the channel and osculum, i.e., from stifled
The minor diameter side for filling in point is released by abrasive grain to major diameter side.
Therefore, the utility model has the advantages that fraction defective is low for inner flange processing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of water channel.
Fig. 3 is the structural schematic diagram that existing grinding wheel is processed inner flange.
Label in attached drawing be：1- ontologies, 2- fixed holes, 3- water channels, 4- rhones, 5- osculums, the existing sand of 6-
Wheel, 7- inner flanges.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of compound emery wheel of automobile hub unit inner flange, as depicted in figs. 1 and 2, including ontology 1, ontology 1
Axial direction is equipped with fixed hole 2, and the side of fixed hole 2 is equipped with the water channel 3 through ontology 1, and water channel 3 is arc and middle part is close
The peripheral surface of the axis of ontology 1, ontology 1 is equipped with rhone 4, and the bottom of rhone 4 is equipped with multiple drainings being connected to water channel 3
Hole 5.
The side wall of the rhone 4 is equipped with outward gradient.
The quantity of the rhone 4 has three, is circumferentially evenly distributed on the peripheral surface of ontology 1.
Big, the intermediate diameter of the diameter at 3 both ends of the water channel is small, and the osculum 5 is speaker hole, the big end of osculum 5
It is connect with water channel 3.
Operation principle：The main shaft of lathe passes through the fixed hole 2 of the utility model to clamp the utility model for internal
The processing of flange 7, cutting fluid is aided in process, and generate a cutting mud part in grinding process arranges from the both ends of rhone
Go out, another part is discharged from osculum through water channel in time, and to the abrasion of inner flange and processing is improved so as to avoid cutting mud
Precision.
Therefore, the utility model has the advantages that fraction defective is low for inner flange processing.
