Abstract
The invention relates to the technical field of machining tools, in particular to a chamfering drill bit. The chamfering bit comprises a drill handle, a drill body and a drill bit body. Cutting blades used for cutting are arranged at the front end of the drill bit body. Rotating tracks of the two cutting blades are arranged on the drill body. A chip discharge groove is formed between the rotating tracks of the two cutting blades. A conical chamfering disc is detachably fixed to the drill bit body, and a plurality of chamfering blades are arranged on a chamfering disc conical surface. According to the chamfering drill bit provided by the invention, the chamfering disc on the drill bit body can be used for directly chamfering drilled holes after drilling is completed through the drill bit body, operation is completed in one step, the structure is simple, operation is easy, and the efficiency is at least doubled. Threaded holes used for fixing the chamfering disc are formed between the chamfering blades, screws are screwed in the threaded holes, the chamfering disc is fixed to the drill bit body through the screws, it is guaranteed that the screwheads of the screws are lower than the surface of the chamfering disc after the chamfering disc is fixed through the screws, and smooth operation of chamfering is guaranteed.
Description
Technical field
The present invention relates to machining tool technical field, especially a kind of chmfer bit.
Background technology
Drill bit is to go out through hole or blind hole to the drilling on solid material, 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
General apex point before this is contacted with solid material, is then gradually advanced again, is completed drilling, is then changed the bigger drill bit of diameter again,
Bore edges to boring carry out chamfered, troublesome poeration, and efficiency comparison is low.
The content of the invention
The technical problem to be solved in the present invention is：In order to solve existing drill bit in drilling and chamfering, need step by step
Complete, troublesome poeration, and the low problem of efficiency comparison, the invention provides a kind of chmfer bit, after drill bit completes drilling,
Chamfering disk on drill bit can directly carry out chamfering to the hole bored, and a step is completed, simple structure, easily operate, and efficiency is carried
It is high at least one times.
The technical solution adopted for the present invention to solve the technical problems is：A kind of chmfer bit, including drillstock, brill body and brill
Head, chisel edge are provided with the cutting blade for cutting, bore the rotational trajectory that body is provided with cutting blade, the rotation of two cutting blades
Chip area is formed between track, chamfering disk on the drill bit, is removably fixed with, the chamfering disk is tapered, the chamfering
Discone antenna surface is provided with some chamfered cutting edges.
The height of chamfering disk can be adjusted according to the depth for being drilled, reduces can stroke of the drill bit in drilling,
Efficiency is improved to a certain extent can.
Specifically, it is provided between the chamfered cutting edge for fixing the screwed hole of chamfering disk.Screw in screwed hole screw,
And chamfering disk is fixed on drill bit by screw, after screw is by the fixation of 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 fixed 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 is used to be arranged the hole of drill bit with one, and two raised, projections are arranged with hole
Match with chip area.
Specifically, the drillstock is externally provided with frosted layer.
The invention has the beneficial effects as follows：A kind of chmfer bit that the present invention is provided, after drill bit completes drilling, on drill bit
Chamfering disk can directly carry out chamfering to the hole bored, and a step is completed, simple structure, easily operate, and efficiency is improve at least
One times；It is provided between chamfered cutting edge for fixing the screwed hole of chamfering disk, screw of screwing in screwed hole, and will be fallen by screw
Angle disk is fixed on drill bit, and after screw is by the fixation of chamfering disk, head of screw will ensure the surface less than chamfering disk, it is ensured that chamfering
Be smoothed out；Bit track is provided with shrinkage pool corresponding with screwed hole, further ensures consolidating for chamfering disk and drill bit
Determine fastness.
