The utility model discloses a kind of machine folder counterbore combination drill, comprise drill bit and cutter hub, it is characterized in that: also comprise annular knurl overcoat, blade, hold out against screw and pad, in cutter hub, be provided with articulation hole, described drill bit loads in cutter hub articulation hole, and cutter hub and drill bit are provided with fluting, described blade loads in fluting, the endoporus of described annular knurl overcoat matches with cutter hub, and the described annular knurl overcoat cylindrical screwed hole that drills and reams holds out against screw for installing, described in hold out against screw and hold out against blade by pad.The utility model solves normal drill bit fluting in prior art and adopts flush type combination with alloy blade, cost is higher, working (machining) efficiency is low, maintenance difficult, and the unmanageable problem of end tooth relief angle, provide a kind of structure simple, easy to use, with low cost, rotary head and blade unit more reasonable, not easily burn cutter, the machine folder counterbore combination drill of cutting speed and working (machining) efficiency can be improved.
Description
Technical field
The utility model relates to a kind of drill bit, particularly relates to a kind of machine folder counterbore combination drill.
Background technology
The counterbore processing of various bolt and screw, be all subdrilling bottom outlet and then with broad complete counterbore processing, this needs to use arrangement gang tool, the entire combination cost of charp tool is higher, cutting ability is poor, and very difficult in the processing of end-tooth coupling part, generally take to cut out escape aft-loaded airfoil end tooth relief angle, such tool strength reduces greatly.
Utility model content
Flush type combination is adopted with alloy blade in order to solve normal drill bit fluting in prior art, cost is higher, working (machining) efficiency is low, maintenance difficult, and the unmanageable problem of end tooth relief angle, it is simple that the utility model provides a kind of structure, easy to use, with low cost, rotary head and blade unit more reasonable, not easily burn cutter, the machine folder counterbore combination drill of cutting speed and working (machining) efficiency can be improved.
In order to solve the problem, technical solution adopted in the utility model is:
A kind of machine folder counterbore combination drill, comprise drill bit and cutter hub, it is characterized in that: also comprise annular knurl overcoat, blade, hold out against screw and pad, in cutter hub, be provided with articulation hole, described drill bit loads in cutter hub articulation hole, and cutter hub and drill bit are provided with fluting, described blade loads in fluting, the endoporus of described annular knurl overcoat matches with cutter hub, and the described annular knurl overcoat cylindrical screwed hole that drills and reams holds out against screw for installing, described in hold out against screw and hold out against blade by pad.
Aforesaid a kind of machine folder counterbore combination drill, is characterized in that: also comprise drill bit adjustment thread spindle, be provided with the drill bit be connected with drill bit and adjust thread spindle in described cutter hub.
Aforesaid a kind of machine folder counterbore combination drill, is characterized in that: described blade adopts alloy blade.
Aforesaid a kind of machine folder counterbore combination drill, it is characterized in that: cutter hub front end is provided with cylinder pillow block, described annular knurl overcoat endoporus matches with cutter hub cylinder pillow block
Aforesaid a kind of machine folder counterbore combination drill, is characterized in that: on cutter hub and drill bit, be axially provided with symmetrical grooving.
Aforesaid a kind of machine folder counterbore combination drill, is characterized in that: described cutter hub adopts stainless steel material to make.
The beneficial effect that the utility model reaches: the utility model machine folder counterbore combination drill, described annular knurl overcoat cylindrical drill and ream screwed hole for install hold out against screw, the described screw that holds out against holds out against blade by pad, and such blade can be installed by quick-replaceable, uses more flexible, be convenient to maintenance, whole tool sharpening is also more simple simultaneously, and cost is lower, and the utility model drill bit and the distribution of blade unit linear velocity are rationally, not easily burn cutter, cutting speed and working (machining) efficiency can be improved.The utility model can once be holed, expand counterbore is shaped, and decreases tool change time, improves effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As Figure 1-3, a kind of machine folder counterbore combination drill, comprise drill bit 1, annular knurl overcoat 2, cutter hub 3, drill bit adjustment thread spindle 4, blade 5, hold out against screw 6 and pad 7, described cutter hub 3 adopts stainless steel material to make, articulation hole is provided with in cutter hub 3, described drill bit 1 loads in cutter hub 3 articulation hole, is provided with the drill bit be connected with drill bit 1 and adjusts thread spindle 4 in described cutter hub 3.
Cutter hub 3 and drill bit 1 are axially provided with symmetrical grooving, described blade 5 loads in fluting, described blade 5 adopts alloy blade, cutter hub 3 front end is provided with cylinder pillow block, described annular knurl overcoat 2 endoporus matches with cutter hub 3 cylinder pillow block, the described annular knurl overcoat 2 cylindrical screwed hole that drills and reams holds out against screw 6 for installing, described in hold out against screw 6 and hold out against blade 5 by pad 7.
The utility model machine folder counterbore combination drill in sum, described annular knurl overcoat 2 cylindrical drill and ream screwed hole for install hold out against screw 6, the described screw 6 that holds out against holds out against blade 5 by pad 7, and such blade 5 can be installed by quick-replaceable, uses more flexible, be convenient to maintenance, simultaneously whole tool sharpening is also more simple, and cost is lower, the utility model drill bit 1 and blade 5 assemble line VELOCITY DISTRIBUTION reasonable, not easily burn cutter, cutting speed and working (machining) efficiency can be improved.The utility model can once be holed, expand counterbore is shaped, and decreases tool change time, improves effect.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
