Abstract
The utility model discloses the composite structures of a kind of drill bit and drill bit installation axle, include drill bit, drill bit installation axle, it is characterised in that: the drill bit includes drill body and drillstock, and side, which is provided with, on the drillstock rises as high as the banks；The drill bit installation axle includes axis body, described axis body one end is equipped with interconnecting piece, drillstock insertion hole is provided with along axial direction in the interconnecting piece, the side of the interconnecting piece is provided with a gap, the briquetting cooperated with gap is equipped in the gap, the bayonet with cooperation of rising as high as the banks on drillstock is equipped on the inside of the briquetting, gap two sides are provided with threaded hole, are also equipped with threaded hole corresponding with gap two sides threaded hole on briquetting.The utility model is risen as high as the banks by being provided on the drillstock of drill bit, it can be by cooperating with the bayonet of drill bit installation axle upper holder block, drill bit can be effectively prevented, slipping phenomenon occurs under the action of high drill thrust, and drill bit is bolted with drill bit installation axle, is convenient for changing.
Description
Technical field
The utility model relates to field of machining, and in particular to a kind of composite structure of drill bit and drill bit installation axle.
Background technique
In machining, carrying out drilling using drilling equipment is common processing method, and existing drill bit generally passes through
It is connected between clamping mechanism, but since some metal works hardness are larger, drill bit is damaged fast speed in use, needs
Periodically drill bit is replaced, existing drill bit connects complex with drilling machine body, is not easy to replace.And it typically now bores
The drillstock of head is circular shaft structure, can only be used in the case where drill thrust is less big, is easy to beat when drill thrust is bigger
It is sliding, influence drilling effect.
Utility model content
Purpose of the utility model is to solve the above problems and provide the composite structures of a kind of drill bit and drill bit installation axle.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of composite structure of drill bit and drill bit installation axle includes drill bit, drill bit installation axle, it is characterised in that: the brill
Head includes drill body and drillstock, and side, which is provided with, on the drillstock rises as high as the banks；The drill bit installation axle includes axis body, and described axis body one end is set
There is interconnecting piece, is provided with drillstock along axial direction in the interconnecting piece and is inserted into hole, the side of the interconnecting piece is provided with a gap, described to slit
It is equipped with the briquetting cooperated with gap in mouthful, the bayonet with cooperation of rising as high as the banks on drillstock is equipped on the inside of the briquetting, gap two sides are provided with
Threaded hole is also equipped with threaded hole corresponding with gap two sides threaded hole on briquetting.
Further, the axis body of the drill bit installation axle is equipped with keyway far from one end of interconnecting piece.
The utility model the utility model has the advantages that the utility model is risen as high as the banks by being provided on the drillstock of drill bit, can by with brill
The bayonet cooperation of head installation axle upper holder block, can be effectively prevented drill bit and slipping phenomenon occurs under the action of high drill thrust, and
Drill bit is bolted with drill bit installation axle, is convenient for changing.
Detailed description of the invention
Fig. 1 is the structural blast schematic diagram of the utility model composite structure；
Fig. 2 is the composite structure scheme of installation of drill bit and drill bit installation axle in the utility model.
Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawing.
As shown in Figs. 1-2, the composite structure of a kind of drill bit of the utility model and drill bit installation axle includes drill bit, drill bit
Installation axle, the drill bit include drill body 1 and drillstock 2, and side, which is provided with, on the drillstock 2 rises as high as the banks 3；The drill bit installation axle includes axis
Body 4, described 4 one end of axis body are equipped with interconnecting piece 5, are provided with drillstock along axial direction in the interconnecting piece 5 and are inserted into hole 6, the interconnecting piece 5
Side is provided with a gap 7, and the briquetting 8 cooperated with gap 7 is equipped in the gap 7, is equipped with and drillstock 2 on the inside of the briquetting 8
On rise as high as the banks the bayonets 9 of 3 cooperations, 7 two sides of gap are provided with threaded hole 10, are also equipped on briquetting 8 corresponding with 7 two sides threaded hole 10 of gap
Threaded hole 11；The axis body 4 of the drill bit installation axle is equipped with keyway 12 far from one end of interconnecting piece.
When the utility model is used, drillstock 2 is inserted into drillstock insertion hole 6, briquetting 8 is then placed on interconnecting piece 5
In gap 7, briquetting 8 is fixed in gap 7 using bolt, what the bayonet 9 on briquetting 8 blocked drillstock 2 rises as high as the banks 3, prevents drillstock 2
Rotation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
