A kind of reverse chip removal reamer of side water outlet, including cutter hub, the cutter hub front end is circumferentially arranged with one group in cutter hub
Heart line symmetrically preceding blade and the front clearance groove corresponding with preceding blade, circumferentially arranged with one group on cutter hub in the middle part of the cutter hub
Symmetrically rear blade and the rear chip area corresponding with rear blade, the preceding blade and rear blade are each attached to the knife to center line
On body；The front portion of the front clearance groove is equipped with the shred holding up plate radially extended, and the external diameter of the shred holding up plate is less than the preceding knife
The processing external diameter of piece, is provided with chip pocket between the shred holding up plate and corresponding preceding blade, the front clearance trench bottom is provided with groove；
It is provided with a central passage, two front side channels and two back side walkways inside the cutter hub, two front side channels are and center
Passage is connected and symmetrical on central passage, and two back side walkways are connected with central passage and on central passage pair
Claim；The front side channel is set towards shred holding up plate, and the front side channel and the angle of the central passage are 20 ° ~ 50 °；It is described
Back side walkway is set towards extreme direction after cutter hub, and the back side walkway and the angle of the central passage are 55 ° ~ 75 °；In described
On the rear end face of the cutter hub, the outlet of the front side channel and back side walkway is respectively positioned on front clearance groove for the import of heart passage
Side wall on.
The central passage does not run through cutter hub.
The water inlet of the front side channel connects with the front end of the central passage, the water inlet of the back side walkway and institute
State the middle part connection of central passage.
The shred holding up plate flushes with cutter hub front end.
The utility model in the front portion of front clearance groove by being respectively provided with the shred holding up plate radially extended, front side channel and center
The angle of passage is 20 ° ~ 50 °, and the coolant sprayed by front side channel changes flow direction after running into shred holding up plate, changes the cold of flow direction
But liquid carries cutting chip and flowed away backward along front clearance groove, can cool down preceding blade, and can discharges cutting chip in time；Rear side
Passage and the angle of central passage are 55 ° ~ 75 °, and the cooling liquid energy sprayed by back side walkway accelerates the discharge of cutting chip；Before
The groove that chip removal trench bottom is set can increase the capacity of front clearance groove.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is left view of the present utility model.
Embodiment
In conjunction with accompanying drawing, the utility model embodiment is described in detail：
As shown in Figure 1 to Figure 3, the reverse chip removal reamer of a kind of side water outlet, including cutter hub 1, the front end of cutter hub 1 is circumferentially arranged with one
On the center line of cutter hub 1, symmetrically preceding blade 2 and the front clearance groove 4 corresponding with preceding blade 2, the middle part of cutter hub 1 are circumferentially set group
Have one group on the center line of cutter hub 1 symmetrically after blade 3 and the rear chip area corresponding with rear blade 3, preceding blade 2 and rear blade
3 are each attached on cutter hub.The front portion of front clearance groove 4 is equipped with the shred holding up plate 5 radially extended, before the external diameter of shred holding up plate 5 is less than
The processing external diameter of blade 2, shred holding up plate 5 are flushed with the front end of cutter hub 1, and chip pocket 6 is provided between shred holding up plate 5 and corresponding preceding blade 2,
The bottom of front clearance groove 4 is provided with groove 7.The inside of cutter hub 1 is provided with 8, two front side channels 9 of a central passage and two back side walkways
10, two front side channels 9 are connected and symmetrical on central passage 8 with central passage 8, and two back side walkways 10 are and center
Passage 8 is connected and symmetrical on central passage 8.The import of central passage 8 is on the rear end face of cutter hub 1, and central passage 8 is not
Through cutter hub 1.The water inlet of front side channel 9 connects with the front end of central passage 8, the water inlet and central passage of back side walkway 10
8 middle part connection, the outlet of front side channel 9 and back side walkway 10 is respectively positioned in the side wall of front clearance groove 4.The direction of front side channel 9
