Abstract
The invention discloses a countersink tool. A mounting hole is formed in one end of a countersink tool bit in the axial direction, and the mounting hole is used for detachably mounting a drilling bit. A threaded hole is formed in the side face of the countersink tool. The lower end of the threaded hole is connected with the mounting hole. According to the technical scheme, the mounting hole and the threaded hole are formed in the countersink tool and combine the countersink tool with the drilling bit, the countersink tool and the drilling bit 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 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 cutter field, particularly relates to counterbore cutter.
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 counterbore cutter.
First aspect, it is provided that a kind of counterbore cutter, described counterbore jet blade one end has peace vertically
Dress hole, described installing hole is for detachably installing drill bit；
Described counterbore cutter side has screwed hole, and described screwed hole lower end is connected with described installing hole
Connect.
The technical scheme provided according to the embodiment of the present application, by arranging installing hole on counterbore cutter
And screwed hole, counterbore cutter and drill bit are combined, can be according to counterbores different in actual production
It is optionally combined with the size of nail, improves the utilization rate of drill bit；Drill bit and counterbore cutter are simultaneously
It is ground, it is ensured that the concordance of counterbore tilt rake angle, it is to avoid the generation of angle circular arc,
Ensure that the size of institute's operation product fully meets the use requirement of 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.
The embodiment of the present invention provides a kind of counterbore cutter, and described counterbore cutter 2 cutter head one end is opened vertically
Having installing hole, described installing hole installs drill bit 1 for detachable；
Described counterbore cutter 2 side has screwed hole 3, described screwed hole 3 lower end and described installation
Hole is connected.
The technical scheme that the embodiment of the present invention provides, by arranging installing hole and spiral shell on counterbore cutter
Pit, combines counterbore cutter and drill bit, as Figure 1-3, and can be according to actual production
The size of middle different counterbore and nail is optionally combined, and improves the utilization rate of drill bit；Drill bit and
Counterbore cutter is ground simultaneously, it is ensured that the concordance of counterbore tilt rake angle, it is to avoid angle
The generation of circular arc, it is ensured that the size of institute's operation product fully meets the use requirement of client.
Further, installing hole cross-section center overlaps with described counterbore cutter cross-section center.
The axis of counterbore cutter and installing hole dead in line, be therefore arranged on the drill bit shaft in installing hole
Line also with counterbore cutter dead in line, it is ensured that drill bit during the use of Combined drill drill
Uniform with counterbore cutter blade stress, accuracy and the use longevity of cutter head to friction plate processing
Life.
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 concordance 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 by counterbore cutter and drill bit are combined, can according in actual production not
It is optionally combined with the size of counterbore and nail, improves the utilization rate of drill bit；Drill bit and counterbore
Cutter is ground simultaneously, it is ensured that the concordance of counterbore tilt rake angle, it is to avoid angle circular arc
Generation, 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.
It will be appreciated by those skilled in the art that invention scope involved in the application, however it is not limited on
State the technical scheme of the particular combination of technical characteristic, also should contain without departing from described simultaneously
In the case of inventive concept, above-mentioned technical characteristic or its equivalent feature carry out combination in any and shape
Other technical scheme become.Such as features described above has with (but not limited to) disclosed herein
The technical scheme that the technical characteristic of similar functions is replaced mutually and formed.
