Surface, right side, right lower incline, lower surface and cambered surface afterwards, the right lower incline be located at the right side and the lower surface it
Between, the cambered surface connects left side, rear surface, right side, right lower incline and the lower surface；It is described gear bits block left side and
The left side of the cutter hub is respectively positioned on the right side of the blade left side, and the rear surface of the gear bits block closely connects with the cutter hub
Touch；There is spacing in the gear bits block lower surface, the external diameter of the gear bits block is less than with blade upper surface in the vertical direction
The radius of machining of the blade, the external diameter of the gear bits block are less than or equal to the external diameter of the cutter hub；The inside edge of the cutter hub
Be axially arranged with central passage and wing passage, the corresponding blade of every wing passage, the wing passage connect the central passage with
The chip area, the extended line of the wing passage center line intersect at the cutting of the blade with the upper surface of corresponding blade
Sword.
The right lower incline of the gear bits block and the angle of gear bits block lower surface are 120 ° ~ 150 °, the left end of the gear bits block
Face and the spacing of blade left side vertically be 0.2 ~ 0.5mm, the gear consider to be worth doing block external diameter it is smaller than blade radius of machining by 0.2 ~
0.5mm, the gear bits block lower surface is parallel with blade upper surface and vertical direction on spacing be 1 ~ 1.2mm.
The gear bits block is welded to connect by rear surface with cutter hub, only needs to change to damage when the front end damage of gear bits block
Gear bits block, reduce reamer use cost.
The gear bits block is alloy gear bits block.
The utility model in cutter hub left end by setting gear bits block, and the spacing kept off between bits block and respective blade is smaller,
It can effectively stop that chip enters the bottom of blind hole, avoid the manual cleaning in later stage, improve operating efficiency；Gear bits block welding is existed
On cutter hub, the gear for only needing to change damage when the front end damage of gear bits block considers block to be worth doing, reduces reamer use cost.

Embodiment
In conjunction with accompanying drawing, the utility model embodiment is described in detail：
As shown in Figures 1 to 5, a kind of rear chip removal reamer for being provided with gear bits block, including cutter hub 1, the left end of cutter hub 1 were provided with along week
To the blade 2 and the chip area 3 corresponding with blade 2 being evenly arranged.The left end of chip area 3 is fixed with gear bits block 4, gear bits block 4
Including left side 5, rear surface, right side, right lower incline 6, lower surface 7 and cambered surface 8, right lower incline 6 is located at right side and following table
Between face 7, right lower incline 6 and the angle of lower surface 7 are 145 °, and the connection of cambered surface 8 left side 5, rear surface, right side, bottom right are oblique
Face 6 and lower surface 7.The left side 5 of gear bits block 4 and the left side 9 of cutter hub 1 are respectively positioned on the right side of the left side of blade 2, gear bits block 4
Left side 5 and the spacing L1 of the left side of blade 2 vertically be 0.3mm, the rear surface that gear considers block 4 to be worth doing is in close contact with cutter hub 1.Gear
The bits lower surface 7 of block 4 is parallel with the upper surface of blade 2 and spacing L2 is 1.1mm, and the external diameter of gear bits block 4 is smaller than the radius of machining of blade 2
0.3mm, the external diameter of gear bits block 4 are identical with the external diameter of cutter hub 1.Cutter hub 1 is axially inside provided with central passage 10 and wing passage
11, the corresponding blade 2 of every wing passage 11, wing passage 11 connects central passage 10 and chip area 3, the center line of wing passage 11
The upper surface of extended line and corresponding blade 2 intersects at the cutting edge of blade 2.
Gear bits block 4 is welded to connect by rear surface and cutter hub 1, and gear bits block 4 is alloy gear bits block.When the front end of gear bits block 4
During damage, it is only necessary to change the gear bits 4 of damage, reamer use cost can be reduced.
When specifically used, reamer clamping the rotation of reamer opposite piece, is cut the hole wall of workpiece on lathe；
In working angles, coolant enters in cutter hub 1 from central passage 10, and the coolant sprayed from wing passage 11 directly sprays to blade 2
Cutting edge, the cutting edge of blade 2 is cooled down, takes away cutting heat；The gear bits lower surface of block 4 and the upper table interplanar distance of blade 2 compared with
Small, most of coolant changes flow direction after running into blade 2, is flowed away along the opposite direction of reamer feeding, the coolant of opposite direction flowing
Chip is carry to flow out from chip area 3, only smaller part of coolant by keep off the bits lower surface of block 4 and the upper surface of blade 2 it
Between gap flow into blind hole front end, because crumb size is relatively large, before chip can not enter blind hole with a small amount of coolant
End.Therefore under the barrier effect of gear bits block 4, chip can only flow out backward with coolant along chip area 3, avoid chip inflow
The front end of blind hole, avoid the manual cleaning in later stage.
