Abstract
The application discloses bench drilling machine, including combination formula drilling drill bit, combination formula drilling drill bit includes: counter bore sword and drill bit, counter bore sword tool bit one end is opened along the axial has the mounting hole, the drill bit demountable installation be in in the mounting hole. Technical scheme according to this application embodiment provides through making up counter bore sword and drill bit, can come random combination according to different counter bores in the actual production and the size of following closely the hole, has improved the utilization ratio of drill bit, drill bit and counter bore sword grind simultaneously, have ensured counter bore sword inclination's uniformity, have avoided the production of contained angle circular arc, and the size of having ensured institute's operation product satisfies customer's operation requirement completely.
Description
Technical field
The disclosure relates generally to drilling machine field, more particularly, to bench drill.
Background technology
Need by drilling machine, friction plate to be holed in friction plate produces, and the grinding of friction plate is needed higher
Precision；When being ground using old-fashioned one-piece drill bit, the angle between counterbore and nail easily produces circular arc, thus affecting
The outward appearance in the institute's operation hole and demand of client can not be fully met；And old-fashioned drill bit can only a kind of counterbore of operation or nail
Hole, working performance is relatively low.
Utility model content
In view of drawbacks described above of the prior art or deficiency are it is desirable to provide a kind of bench drill.
In a first aspect, providing a kind of bench drill, including Combined drill drill, described Combined drill drill includes：
Counterbore knife and drill bit, described counterbore knife cutter head one end has installing hole vertically, and described drill bit is removably mounted at described installation
In the hole.
The technical scheme being provided according to the embodiment of the present application, by counterbore knife and drill bit are combined, can be according to reality
The size of border different counterbores and nail in producing, to be optionally combined, improves the utilization rate of drill bit；Drill bit and counterbore knife enter simultaneously
Row grinds it is ensured that the concordance of counterbore tilt rake angle, it is to avoid angle circular arc produce it is ensured that the chi of institute's operation product
The very little use requirement fully meeting client.
Brief description
By reading the detailed description that non-limiting example is made made with reference to the following drawings, other of the application
Feature, objects and advantages will become more apparent upon：
Fig. 1 is Combined drill drill front view in this utility model embodiment；
Fig. 2 is Combined drill drill top view in this utility model embodiment；
Fig. 3 is Combined drill drill right view in this utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples the application is described in further detail.It is understood that this place is retouched
The specific embodiment stated is used only for explaining relevant utility model, rather than the restriction to this utility model.Further need exist for explanation
, for the ease of description, in accompanying drawing, illustrate only the part related to utility model.
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Mutually combine.To describe the application below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Refer to Fig. 1-3, this utility model embodiment provides a kind of bench drill, including Combined drill drill, combine
Formula drill includes：Counterbore knife 2 and drill bit 1, described counterbore knife 2 cutter head one end has installing hole vertically, and described drill bit can
Remove and install in described installation in the hole.
The bench drill that this utility model embodiment provides, can be according to reality by counterbore knife and drill bit combine
In production, the size of different counterbores and nail, to be optionally combined, improves the utilization rate of drill bit；Drill bit is arranged on counterbore knife
Top, counterbore knife and drill bit can be polished simultaneously, generate two holes simultaneously, improve production efficiency and the utilization of drill bit
Rate.
Further, installing hole cross-section center is overlapped with described counterbore knife cross-section center.The axis of counterbore knife and peace
Dress axially bored line overlaps, be therefore arranged on install the drill axis of in the hole also with counterbore knife dead in line it is ensured that in bench drill
Use during drill bit and counterbore knife blade stress uniform, the accuracy to friction plate processing and the use longevity of cutter head
Life.
Installing hole in the present embodiment can be through hole or blind hole；If through hole is then capable of various length
Drill bit installation, if blind hole, then the other end of bench drill relatively has larger intensity.
Further, counterbore knife 2 side has screwed hole 3, and described screwed hole 3 lower end is connected with described installing hole.
Further, screw thread in the hole is removably connected with bolt.Open screwed hole in counterbore knife side, by bolt to drill bit
Carry out tightening fixing it is ensured that its in use without departing from or drop.
Further, drill bit includes drill and knife bar, and described knife bar is arranged on described installation in the hole.
Further, screwed hole and the distance no more than described knife bar of described counterbore knife bit tip are arranged on described installation
The length of in the hole.Drill bit knife bar is arranged on installation in the hole, is fixed by the bolt of screw thread in the hole, therefore knife bar puts in peace
The length of dress in the hole needs the distance more than installing hole and counterbore knife cutter head, just enables the good fixation to drill bit, in polishing
During relatively stable.
Further, bolt is contacted with described knife bar.
Further, counterbore knife is 3-edge surgical knife.Counterbore knife in the present embodiment is 3-edge surgical knife, increased bench drill operation
Balance, decrease jitter phenomenon when counterbore knife is contacted in operation process with product it is ensured that counterbore size stablize one
Cause property；And ensure that the concordance of counterbore tilt rake angle by the combination of counterbore knife and drill bit, it is to avoid angle circular arc
Produce it is ensured that the size of All Jobs product fully meets demand.
The present embodiment provide bench drill by counterbore knife and drill bit are combined, can according in actual production not
Size with counterbore and nail to be optionally combined, and improves the utilization rate of drill bit；Drill bit and counterbore knife be ground simultaneously it is ensured that
The concordance of counterbore tilt rake angle, it is to avoid the generation of angle circular arc is it is ensured that the size of institute's operation product fully meets
The use requirement of client.Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.Ability
Field technique personnel should be appreciated that involved utility model scope in the application however it is not limited to the specific group of above-mentioned technical characteristic
The technical scheme closed, also should cover in the case of without departing from the design of described utility model, by above-mentioned technical characteristic simultaneously
Or other technical schemes that its equivalent feature carries out combination in any and formed.Such as features described above with disclosed herein (but
It is not limited to) there is the technical scheme that the technical characteristic of similar functions is replaced mutually and formed.
