Description
Technical field
The utility model is related to machining tool technical field, especially a kind of chmfer bit.
Background technology
Drill bit is to be used to the drilling on solid material to go out through hole or blind hole, and can be to the cutter of existing hole reaming.Drill bit
In drilling, mainly workpiece is cut by bit tip, chip is discharged by chip area.Drill bit is when work
Typically apex point is contacted with solid material before this, is then gradually promoted again, completes drilling, the bigger drill bit of diameter is then changed again,
Chamfered, troublesome poeration are carried out to the bore edges of brill, and efficiency comparison is low.
Utility model content
The technical problems to be solved in the utility model is：In order to solve existing drill bit in drilling and chamfering, it is necessary to divide
The problem of step completion, troublesome poeration, and efficiency comparison are low, the utility model provides a kind of chmfer bit, complete in drill bit
Into after drilling, the chamfering disk on drill bit can directly carry out chamfering to the hole of brill, and a step is completed, simple in construction, easily operation, and
Efficiency is improved at least one times.
The utility model solves the technical scheme that its technical problem used：A kind of chmfer bit, including drillstock, brill body
And drill bit, chisel edge, which is provided with, is used for the cutting blade of cutting, bores the rotational trajectory that body is provided with cutting blade, two cutting blades
It is formed between rotational trajectory on chip area, the drill bit and is removably fixed with chamfering disk, the chamfering disk is described to be tapered
Chamfering discone antenna surface is provided with some chamfered cutting edges.
The height of chamfering disk can be adjusted according to the depth drilled, can reduce stroke of the drill bit in drilling,
Efficiency can be improved to a certain extent.
Specifically, the screwed hole for being used for fixing chamfering disk is provided between the chamfered cutting edge.Screw is screwed in screwed hole,
And chamfering disk is fixed on drill bit by screw, after screw fixes chamfering disk, head of screw will ensure less than chamfering disk
Surface, it is ensured that chamfering is smoothed out.
In order to be further ensured that the fixation fastness of chamfering disk and drill bit, the bit track is provided with and screwed hole pair
The shrinkage pool answered.
Specifically, the chamfering disk, which has in a hole for being used to be arranged drill bit, hole, is arranged with two projections, the projection
Match with chip area.
Specifically, the drillstock is externally provided with frosted layer.
The beneficial effects of the utility model are：A kind of chmfer bit that the utility model is provided, after drill bit completes drilling,
Chamfering disk on drill bit can directly carry out chamfering to the hole of brill, and a step is completed, simple in construction, easily operation, and efficiency is carried
It is high at least one times；The screwed hole for being used for fixing chamfering disk is provided between chamfered cutting edge, screw is screwed in screwed hole, and pass through
Chamfering disk is fixed on drill bit by screw, after screw fixes chamfering disk, and head of screw will ensure the surface less than chamfering disk, is protected
Being smoothed out for chamfering is demonstrate,proved；Bit track be provided with shrinkage pool corresponding with screwed hole, further ensure chamfering disk and
The fixation fastness of drill bit.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of chmfer bit of the present utility model；
Fig. 2 is the sectional view of chamfering disk of the present utility model.
In figure：1. drillstock, 2. brill bodies, 3. drill bits, 4. cutting blades, 5. rotational trajectories, 6. chip areas, 7. chamfering disks, 8.
Chamfered cutting edge, 9. screwed holes, 10. shrinkage pools, 11. holes, 12. is raised, 13. frosted layers.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in Figure 1 and Figure 2, a kind of chmfer bit, including drillstock 1, brill body 2 and drill bit 3, the front end of drill bit 3, which is provided with, to be used to cut
The cutting blade 4 cut, bores and is formed between the rotational trajectory 5 that body 2 is provided with cutting blade 4, the rotational trajectory 5 of two cutting blades 4
Chamfering disk 7 is removably fixed with chip area 6, drill bit 3, chamfering disk 7 is tapered, and the conical surface of chamfering disk 7 is provided with some chamferings
The screwed hole 9 for being used for fixing chamfering disk 7 is provided between blade 8, chamfered cutting edge 8.
In a kind of embodiment, the rotational trajectory 5 of drill bit 3 is provided with shrinkage pool 10 corresponding with screwed hole 9.
Preferably, chamfering disk 7, which has in a hole 11 for being used to be arranged drill bit 3, hole 11, is arranged with two projections 12, it is convex
Play 12 with chip area 6 to match, so ensure that the job stability of chamfering disk 7.
Preferably, drillstock 1 is externally provided with frosted layer 13.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
