Description

Counterbore knife

Technical field

The disclosure relates generally to cutter field, more particularly to counterbore knife.

Background technology

Need to drill to friction plate by drilling machine in friction plate production, and it is higher to the grinding needs of friction plate Precision；Angle when being ground using old-fashioned one-piece drill bit between counterbore and nail easily produces circular arc, so as to influence The outward appearance in institute's operation hole and the demand of client can not be fully met；And old-fashioned drill bit can only a kind of counterbore of operation or nail Hole, operating efficiency is relatively low.

Utility model content

In view of drawbacks described above of the prior art or deficiency, expect to provide a kind of counterbore knife.

First aspect is provided with mounting hole, the mounting hole vertically there is provided a kind of counterbore knife, described counterbore knife cutter head one end For detachably installing drill bit；

The counterbore knife side is provided with screwed hole, and the screwed hole lower end is connected with the mounting hole.

The technical scheme provided according to the embodiment of the present application, will be heavy by setting mounting hole and screwed hole on counterbore knife Hole knife and drill bit combine, and can be optionally combined according to the size of different counterbores and nail in actual production, improve brill The utilization rate of head；Drill bit and counterbore knife are ground simultaneously, it is ensured that the uniformity of counterbore tilt rake angle, it is to avoid angle circle The generation of arc, it is ensured that the size of institute's operation product fully meets the use requirement of client.

Brief description of the drawings

By reading the detailed description made to non-limiting example made with reference to the following drawings, the application's is other Feature, objects and advantages will become more apparent upon：

Fig. 1 is Combined drill drill front view in the utility model embodiment；

Fig. 2 is Combined drill drill top view in the utility model embodiment；

Fig. 3 is Combined drill drill right view in the utility model embodiment.

Embodiment

The application is described in further detail with reference to the accompanying drawings and examples.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 the utility model.Further need exist for explanation , for the ease of description, the part related to utility model is illustrate only in accompanying drawing.

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The utility model embodiment provides a kind of counterbore knife, and described cutter head one end of counterbore knife 2 is provided with mounting hole vertically, institute Stating mounting hole is used to detachably install drill bit 1；

The side of counterbore knife 2 is provided with screwed hole 3, and the lower end of screwed hole 3 is connected with the mounting hole.

The technical scheme that the utility model embodiment is provided, will be heavy by setting mounting hole and screwed hole on counterbore knife Hole knife and drill bit combine, as Figure 1-3, can come random group according to the size of different counterbores and nail in actual production Close, improve the utilization rate of drill bit；Drill bit and counterbore knife are ground simultaneously, it is ensured that the uniformity 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 the use requirement of client.

Further, mounting hole cross-section center is overlapped with the counterbore knife cross-section center.

The axis of counterbore knife with install axially bored line overlaps, therefore be arranged on mounting hole in drill axis also with counterbore cutter shaft Line is overlapped, it is ensured that drill bit and counterbore knife blade stress is uniform during the use of Combined drill drill, to friction plate The accuracy of processing and the service life of cutter head.

Further, it is removably connected with bolt in screwed hole.Screwed hole is opened in counterbore knife side, by bolt to drill bit Fixation is tightened in progress, it is ensured that its in use without departing from or drop.

Further, drill bit includes drill and knife bar, and the knife bar is arranged in the mounting hole.

Further, screwed hole is not more than the knife bar with the distance of the counterbore knife bit tip and installed installed in described Length in hole.Drill bit knife bar is arranged in mounting hole, is fixed by the bolt in screwed hole, therefore knife bar puts in peace Length in dress hole needs to be more than the distance of mounting hole and counterbore knife cutter head, the good fixation to drill bit could be realized, in polishing During it is relatively stable.

Further, bolt is in contact with the knife bar.

Further, counterbore knife is 3-edge surgical knife.Counterbore knife in the present embodiment is 3-edge surgical knife, adds Combined drill hole drill The balance of head operation, reduces jitter phenomenon when counterbore knife is contacted with product in operation process, it is ensured that counterbore size Stable and consistent；And it ensure that the uniformity of counterbore tilt rake angle by the combination of counterbore knife and drill bit, it is to avoid angle The generation of circular arc, it is ensured that the size of all operation products fully meets demand.

The present embodiment, can be according to different counterbore in actual production and nail by the way that counterbore knife and drill bit are combined Size is optionally combined, and improves the utilization rate of drill bit；Drill bit and counterbore knife are ground simultaneously, it is ensured that counterbore tilt oblique angle The uniformity of degree, it is to avoid the generation of angle circular arc, 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.People in the art Member should be appreciated that utility model scope involved in the application, however it is not limited to the particular combination of above-mentioned technical characteristic Technical scheme, while should also cover in the case where not departing from utility model design, by above-mentioned technical characteristic or its be equal Feature be combined formed by other technical schemes.Such as features described above has with (but not limited to) disclosed herein The technical characteristic for having similar functions carries out technical scheme formed by replacement mutually.
