Description
Technical field
The utility model is related to machining tool technical field, especially a kind of interior chip-removal drill 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 drilling when, by
Rotated in the high speed of drill bit, certain chip can be caused to splash, huge potential safety hazard is there is to operator.
Utility model content
The technical problems to be solved in the utility model is：In order to solve existing drill bit in drilling, due to the height of drill bit
Speed rotation, can cause certain chip to splash, and the problem of huge potential safety hazard is there is to operator, the utility model is provided
A kind of interior chip-removal drill bit, in drilling, the chip of cutting blade cutting moves, is received into brill body upwards along interior chip area
Interior, after drilling terminates, Action of Gravity Field is automatically drained out, it is entirely avoided occur the phenomenon to external chip discharging, structure in boring procedure
Simply, it is safe and reliable.
The utility model solves the technical scheme that its technical problem used：A kind of interior chip-removal drill bit, including drillstock, brill
Body and drill bit, chisel edge are provided with the cutting blade for cutting, and the brill is as core drill body, and the brill body is interior provided with cutting
Interior chip area is formed between the rotational trajectory of blade, the rotational trajectory of cutting blade.
Specifically, the rotational trajectory bored provided with 4 groups of cutting blades in body.
Preferably, the brill body is provided with the chip removal mouth for being easy to bore chip discharge inside body.Boring the chip in body
When excessive, it can be discharged by chip removal mouth, while chip removal mouth can also overflow as an observation window when there is chip in chip removal mouth
Go out, drilling can be stopped, the chip in body is bored in cleaning.
Specifically, the drillstock is externally provided with frosted layer.
The beneficial effects of the utility model are：The utility model provides a kind of interior chip-removal drill bit, in drilling, bite
The chip of sword cutting, is moved upwards along interior chip area, is received into brill body, after drilling terminates, Action of Gravity Field is automatically drained out, complete
The phenomenon occurred in boring procedure to external chip discharging is avoided entirely, it is simple in construction, it is safe and reliable；Bore body and be provided with and be easy to bore body
The chip removal mouth of internal chip discharge, when the chip in brill body is excessive, can be discharged, while chip removal mouth can also by chip removal mouth
As an observation window, when there is chip spilling in chip removal mouth, drilling can be stopped, the chip in body is bored in cleaning, simple in construction, real
It is strong with property.
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 interior chip-removal drill bit of the present utility model；
Fig. 2 is a kind of partial cross-sectional perspective view of interior chip-removal drill bit of the present utility model.
In figure：1. bodies are bored drillstock, 2., 3. drill bits, 4. cutting blades, 5. rotational trajectories, chip area in 6., 7. chip removal mouths,
8. frosted layer.
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 interior chip-removal drill bit 3, including drillstock 1, brill body 2 and drill bit 3, the front end of drill bit 3 is provided with use
In the cutting blade 4 of cutting,：Brill body 2 is core drill body, bores the rotational trajectory 5 that cutting blade 4 is provided with body 2, cutting blade 4
Rotational trajectory 5 between be formed with interior chip area 6.
In this specific embodiment, the rotational trajectory 5 provided with 4 groups of cutting blades 4 in body 2 is bored.
In a kind of embodiment, bore the top of body 2 and be provided with the chip removal mouth 7 for being easy to bore the inside chip discharge of body 2.Boring
When chip in body 2 is excessive, it can be discharged by chip removal mouth 7, while chip removal mouth 7 can also work as chip removal as an observation window
There is chip spilling in mouth 7, drilling can be stopped, the chip in body 2 is bored in cleaning.
Preferably, drillstock 1 is externally provided with frosted layer 8.
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.
