Description
Technical field
This utility model belongs to drilling tool technical field, refers in particular to a kind of removable drill bit of cutter head.
Background technology
Drill bit needs constantly to external chip discharging during work, just can ensure that the smooth and easy of drilling, not so gives up
Bits are stayed in hole, tend to interfere with bit operation, but also the precision of workpiece can be produced impact, so drill bit
On be designed with chip area, and be helical form, facilitate drill bit chip removal under rotation, but current chip area
Bigger with the angle of drill bit axis so that the cincture number of turns of chip area is too much, not only add manufacture difficulty
Degree, the ability of chip removal simultaneously is affected；The most in the course of the work, can produce relatively between drill bit and workpiece
High temperature, if lowered the temperature not in time, can affect the life-span of drill bit and the quality of product.
Summary of the invention
The purpose of this utility model is to provide the removable brill of cutter head that a kind of chip removal is smooth and easy, carry cooling effect
Head.
The purpose of this utility model is achieved in that the removable drill bit of cutter head, and the outer wall of drill bit is arranged
Having chip area, chip area uses the production technology of traditional fully grinding fluted drill to be made, and grinding technology is protected
Stay fluted drill traditional advantage in chip removal, maintained the smooth and easy of chip removal, making has used emery wheel grind,
Greatly reducing the production cycle, compare more traditional machining center milling technique, the use reducing instrument becomes
This, described chip area is internally provided with pod apertures, wherein, described drill bit is provided with ring flange, described method
Blue dish side is installation portion, and opposite side is drilling portion, and described chip area is arranged in described drilling portion, in spiral shell
Rotation shape, and the angle formed with the axis of drill bit is less than 20 °, decreases chip area spiral in drilling portion
The number of turns, convenient manufacture, improve chip removal ability simultaneously；Described pod apertures extends to from the bottom of installation portion
The end in described drilling portion, the end face in described drilling portion is provided with two spray holes, two described spray hole phases
The most symmetrical, described spray hole is obliquely installed, and connects with described pod apertures, and described spray hole can be with workpiece
Machined surface close contact, it is fastest to use liquid, and sphere of action is more accurate.
The removable drill bit of cutter head mentioned above, wherein, described pod apertures is positioned at the axis of described drill bit
On.
The removable drill bit of cutter head mentioned above, wherein, the inlet of described pod apertures is provided with cone tank,
Convenient when installing, it is possible to the feed tube rapid abutting joint of equipment, and to prevent leakage.
The removable drill bit of cutter head mentioned above, wherein, the afterbody of described installation portion is provided with slot,
Drill bit is made to install more convenient, faster.
This utility model is prominent compared to existing technology and useful having the technical effect that chip area can quickly be arranged
Bits, and are prevented from scrap and are blocked in work surface, improve work efficiency, and the pod apertures energy of self
Enough machined surfaces that drilling liquid is transported to workpiece accurately, eliminate high temperature produced by drilling timely, and
Contribute to the discharge of scrap, improve machining accuracy.

Machining center milling technique, reduces the use cost of instrument, and described chip area 13 is internally provided with pod apertures
14, described pod apertures 14 is positioned on the axis of described drill bit, and the inlet of described pod apertures 14 is provided with
Cone tank 16, convenient when installing, it is possible to the feed tube rapid abutting joint of equipment, and to prevent leakage, wherein,
Being provided with ring flange 12 on described drill bit, described ring flange 12 side is installation portion 11, described installation portion 11
Afterbody be provided with slot 17, make drill bit install more convenient, faster, opposite side is drilling portion 10, institute
State chip area 13 to be arranged in described drilling portion 10, in the shape of a spiral, and the folder of the axis formation with drill bit
Angle is less than 20 °, decreases chip area 13 number of turns of spiral in drilling portion 10, convenient manufacture, carries simultaneously
High chip removal ability；Described pod apertures 14 extends to the end in described drilling portion 10 from the bottom of installation portion 11,
The end face in described drilling portion 10 is provided with two spray holes 15, and two described spray holes 15 are symmetrical, institute
State spray hole 15 to be obliquely installed, connect with described pod apertures 14, form y-type structure, described spray hole 15
Can be with the machined surface close contact of workpiece, it is fastest to use liquid, and sphere of action is more accurate, Er Qieneng
Enough formation repulsions on machined surface, spray scrap, beneficially chip removal.
Above-described embodiment is only preferred embodiment of the present utility model, limits guarantor of the present utility model the most according to this
Protect scope, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should contain
