Abstract
The invention discloses a combined drilling bit. The combined drilling bit comprises a countersink tool and a drilling bit body. A mounting hole is formed in one end of a countersink tool bit in the axial direction, and the drilling bit body is detachably mounted in the mounting hole. According to the technical scheme, the countersink tool and the drilling bit body are combined and can be freely combined according to the sizes of different countersinks and nail holes in actual production, and the utilization rate of the drilling bit is increased; the drilling bit body and the countersink tool conduct grinding at the same time, the consistency of the inclination angle of the countersink tool is guaranteed, generation of an included-angle circular arc is avoided, and it is guaranteed that the sizes of all work products completely meet the use requirements of customers.
Description
Technical field
The disclosure relates generally to bench drill field, is specifically related to for processing the desk-top of friction plate
Drilling machine, particularly relates to Combined drill drill.
Background technology
Need by drilling machine, friction plate to be holed in friction plate produces, and to friction plate
Grind and need higher precision；Counterbore and nail when using old-fashioned one-piece drill bit to be ground
Between angle easily produce circular arc, thus affect the outward appearance in institute's operation hole and can not expire completely
The demand of foot client；And old-fashioned drill bit can only operation one counterbore or nail, operation imitate
Rate is relatively low.
Summary of the invention
In view of drawbacks described above of the prior art or deficiency, it is desirable to provide a kind of Combined drill hole drill
Head.
First aspect, it is provided that a kind of Combined drill drill, including: counterbore cutter and drill bit, institute
Stating counterbore jet blade one end and have installing hole vertically, described drill bit is removably mounted at described peace
In dress hole.
The technical scheme provided according to the embodiment of the present application, by combining counterbore cutter and drill bit
Come, can be optionally combined according to the size of counterbores different in actual production and nail, improve
The utilization rate of drill bit；Drill bit and counterbore cutter are ground simultaneously, it is ensured that counterbore tilt rake angle
Uniformity, it is to avoid the generation of angle circular arc, it is ensured that the size of institute's operation product is the fullest
The use requirement of foot client.
Accompanying drawing explanation
The detailed description that non-limiting example is made made with reference to the following drawings by reading,
Other features, purpose and advantage will become more apparent upon:
Fig. 1 is Combined drill drill front view in the embodiment of the present invention；
Fig. 2 is Combined drill drill top view in the embodiment of the present invention；
Fig. 3 is Combined drill drill right view in the embodiment of the present invention.
Detailed description of the invention
With embodiment, the application is described in further detail below in conjunction with the accompanying drawings.It is appreciated that
, specific embodiment described herein is used only for explaining related invention, rather than to this
Bright restriction.It also should be noted that, for the ease of describe, accompanying drawing illustrate only with
The part that invention is relevant.
It should be noted that in the case of not conflicting, the embodiment in the application and embodiment
In feature can be mutually combined.Describe this below with reference to the accompanying drawings and in conjunction with the embodiments in detail
Application.
Refer to Fig. 1-3, the embodiment of the present invention provides a kind of Combined drill drill, including: heavy
Hole cutter 2 and drill bit 1, described counterbore cutter 2 cutter head one end has installing hole, described brill vertically
Head is removably mounted in described installing hole.
The Combined drill drill that the embodiment of the present invention provides is by combining counterbore cutter and drill bit
Come, can be optionally combined according to the size of counterbores different in actual production and nail, improve
The utilization rate of drill bit；Drill bit is arranged on the top of counterbore cutter, counterbore cutter and drill bit can be simultaneously
Polish, generate two holes simultaneously, improve the utilization rate of production efficiency and drill bit.
Further, installing hole cross-section center overlaps with described counterbore cutter cross-section center.Heavy
The axis of hole cutter and installing hole dead in line, be therefore arranged on the drill axis in installing hole also with
Counterbore cutter dead in line, it is ensured that drill bit and counterbore during the use of Combined drill drill
Cutter blade stress uniform, accuracy and the service life of cutter head to friction plate processing.
Installing hole in the present embodiment can be through hole, it is also possible to for blind hole；If through hole then can
Enough realize the installation of the drill bit of various length, if blind hole, then another of Combined drill drill
End has bigger intensity relatively.
Further, counterbore cutter 2 side has screwed hole 3, described screwed hole 3 lower end and institute
State installing hole to be connected.
Further, it is removably connected with bolt in screwed hole.At counterbore cutter side opening screwed hole,
Drill bit is tightened fixing by bolt, it is ensured that its in use without departing from or fall
Fall.
Further, drill bit includes that drill and knife bar, described knife bar are arranged in described installing hole.
Further, screwed hole is not more than described knife bar with the distance on described counterbore jet blade top
It is arranged on the length in described installing hole.Drill bit knife bar is arranged in installing hole, passes through screw thread
Bolt in hole is fixed, and the length in therefore knife bar puts in installing hole needs more than installing hole
With the distance of counterbore jet blade, could realize the good of drill bit is fixed, in bruting process relatively
It is stable.
Further, bolt contacts with described knife bar.
Further, counterbore cutter is 3-edge surgical knife.Counterbore cutter in the present embodiment is 3-edge surgical knife, increases
Add the balance of Combined drill drill operation, decrease counterbore cutter and product in operation process
Jitter phenomenon during contact, it is ensured that the stable and consistent of counterbore size；And by counterbore cutter
Combination with drill bit ensure that the uniformity of counterbore tilt rake angle, it is to avoid the product of angle circular arc
Raw, it is ensured that the size of All Jobs product fully meets demand.
The present embodiment provide Combined drill drill by counterbore cutter and drill bit are combined,
Can be optionally combined according to the size of counterbores different in actual production and nail, improve drill bit
Utilization rate；Drill bit and counterbore cutter are ground simultaneously, it is ensured that the one of counterbore tilt rake angle
Cause property, it is to avoid the generation of angle circular arc, it is ensured that the size of institute's operation product fully meets visitor
The use requirement at family.
The preferred embodiment of the application and the explanation to institute's application technology principle.Art technology
Personnel should be appreciated that invention scope involved in the application, however it is not limited to above-mentioned technical characteristic
The technical scheme of particular combination, also should contain without departing from described inventive concept simultaneously
In the case of, above-mentioned technical characteristic or its equivalent feature carry out being combined and other skill of being formed
Art scheme.Such as features described above and (but not limited to) disclosed herein have similar functions
The technical scheme that technical characteristic is replaced mutually and formed.
