The utility model has the advantages of novel in design, simple structure reduce the tool changing time, put forward high pressure heater work efficiency rate, increase the cylindricity of hole.
Description
Technical field
The utility model is related to cutting-tool engineering field, more particularly to a kind of drilling reamer.
Background technology
Generally all it is first to carry out the roughing operation such as drill when endoporus is processed in field of machining, reuses reamer
Hole to being drilled carries out fraising finishing, and such procedure of processing needs frequently to change cutter, and operating efficiency is relatively low, wastes
Labour, time, and error can be produced during calibrating to knife again, affect the precision of processing endoporus.
Utility model content
The purpose of this utility model is to provide a kind of drilling reamer for the deficiencies in the prior art, and the drilling reamer design is new
Grain husk, simple structure, reduce tool change time, improve working (machining) efficiency, increase the cylindricity of endoporus.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions.
A kind of drilling reamer, includes handle of a knife, and cutter head is provided with handle of a knife one end, and cutter head upper end is provided with drill bit and reamer
Head, bit upper end is provided with two drill bit swords and corresponding and spiral drill bit side edge, and reamer head upper end is provided with two
Individual reamer end sword and corresponding and spiral reamer side edge, reamer head is provided with support sword with drill bit junction.
Wherein, the handle of a knife is provided with chamfering a for 20 ° with cutter head junction.
Wherein, the angle b between the drill bit sword is 118 °.
Wherein, the angle c between the sword of the reamer end is 90 °.
The beneficial effects of the utility model are：A kind of drilling reamer described in the utility model, includes handle of a knife, handle of a knife one end
On be provided with cutter head, cutter head upper end is provided with drill bit and reamer head, bit upper end be provided with two drill bit swords and it is corresponding simultaneously
Spiral drill bit side edge, reamer head upper end is provided with two reamer end swords and corresponding and spiral reamer side edge,
Reamer head is provided with support sword with drill bit junction.The utility model has novel in design, simple structure, reduces tool change time,
Working (machining) efficiency is improved, increases the advantage of the cylindricity of endoporus.
Description of the drawings
The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing do not constitute it is right
Any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation that the utility model cutter head amplifies；.
Include in Fig. 1-2：
1 --- handle of a knife 2 --- cutter head
21 --- drill bit 211 --- drill bit swords
212 --- drill bit side edge 22 --- reamer heads
221 --- reamer end sword 222 --- reamer side edges
223 --- support sword.
Specific embodiment
The utility model is illustrated with reference to specific embodiment.
As shown in Figure 1-2, a kind of drilling reamer, includes handle of a knife 1, and cutter head 2 is provided with the one end of handle of a knife 1, and the upper end of cutter head 2 sets
Drill bit 21 and reamer head 22 are equipped with, the upper end of drill bit 21 is provided with two drill bit swords 211 and corresponding and spiral drill bit
Side edge 212, the upper end of reamer head 22 is provided with two reamer end swords 221 and corresponding and spiral reamer side edge 222, reamer
22 are provided with support sword 223 with the junction of drill bit 21.
Further, the handle of a knife 1 is provided with chamfering a for 20 ° with the junction of cutter head 2.
Further, the angle b between the drill bit sword 211 is 118 °.
Further, the angle c between reamer end sword 221 is 90 °.
Need to further explain, together with the utility model is combined using drill bit 21 with reamer head 22, reduce tool change time,
Improve working (machining) efficiency；The design for supporting sword 223 is provided with using reamer head 22 and the junction of drill bit 21, increases the cylinder of endoporus
Degree, therefore novel in design, simple structure, reduce tool change time, improve working (machining) efficiency, increase the advantage of the cylindricity of endoporus.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, will change in specific embodiments and applications, this specification content should not be construed as
To restriction of the present utility model.
