Abstract
The invention discloses a bench drilling machine which comprises a combined boring bit. The combined boring bit comprises a countersinking cutter and a drill bit. A mounting hole is formed in one end of the cutting head of the countersinking cutter in the axial direction. The drill bit is detachably mounted in the mounting hole. According to the technical scheme provided by the invention, the countersinking cutter can be randomly combined with the drill bit according to the sizes of different counterbores and nail holes in the actual production, so that the utilization rate of the drill bit is improved; and the drill bit and the countersinking cutter are ground synchronously, so that the consistency of the angle of inclination of the countersinking cutter is ensured, included angle circular arcs are prevented from being generated, and the condition that the sizes of all products meet the using requirements of users completely is ensured.
Description
Technical field
The disclosure relates generally to drilling machine field, particularly relates to bench 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 bench drill.
First aspect, it is provided that a kind of bench drill, including Combined drill drill, described combination
Formula drill includes: counterbore cutter and drill bit, and described counterbore jet blade one end has peace vertically
Dress hole, described drill bit is removably mounted in described installing 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
Concordance, 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
By reading retouching in detail with reference to made non-limiting example is made of the following drawings
Stating, 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 bench drill, holes including combination type
Drill bit, Combined drill drill includes: counterbore cutter 2 and drill bit 1, described counterbore cutter 2 cutter head
One end has installing hole vertically, and described drill bit is removably mounted in described installing hole.
The bench drill that the embodiment of the present invention provides, can by counterbore cutter and drill bit being combined
It is optionally combined with the size according to counterbores different in actual production and nail, improves drill bit
Utilization rate；Drill bit is arranged on the top of counterbore cutter, counterbore cutter and drill bit can carry out beating simultaneously
Mill, generates two holes simultaneously, improves 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 cutter blade during the use of bench drill
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 realizing the installation of the drill bit of various length, if blind hole, then the other end of bench drill is relative
There is bigger intensity.
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 bench drill operation, when decreasing that in operation process, counterbore cutter contacts with product
Jitter phenomenon, it is ensured that the stable and consistent of counterbore size；And by counterbore cutter and drill bit
Combination ensure that the concordance of counterbore tilt rake angle, it is to avoid the generation of angle circular arc, really
The size having protected All Jobs product fully meets demand.
The bench drill that the present embodiment provides, can be by by counterbore cutter and drill bit being combined
Size according to counterbores different in actual production and nail is optionally combined, and improves the utilization of drill bit
Rate；Drill bit and counterbore cutter are ground simultaneously, it is ensured that the concordance of counterbore tilt rake angle,
Avoid the generation of angle circular arc, it is ensured that the size of institute's operation product fully meets making of client
With requiring.Above description is only the preferred embodiment of the application and to institute's application technology principle
Explanation.It will be appreciated by those skilled in the art that invention scope involved in the application, not
It is limited to the technical scheme of the particular combination of above-mentioned technical characteristic, also should contain simultaneously and not take off
In the case of described inventive concept, above-mentioned technical characteristic or its equivalent feature carry out any group
Other technical scheme closed and formed.Such as features described above and (but not limited to) disclosed herein
The technical characteristic with similar functions is replaced mutually and the technical scheme that formed.
