A kind of high efficiency, high life drilling reamer structure, comprise overall cylindrical cutter hub and the knife bar of drilling and reaming, the described cutter hub that drills and reams comprises the Rhizoma Sparganii blade arranged vertically for a pair, described Rhizoma Sparganii blade comprises drill bit segment, changeover portion, the section of finish reaming, the diameter of described drill bit segment is less than the diameter of changeover portion, the diameter of described changeover portion is less than the diameter of the section of finish reaming, described in the diameter of the section of finish reaming be less than the diameter of knife bar.
Be provided with chip area between Rhizoma Sparganii blade described in the utility model, described chip area is straight trough.
Rhizoma Sparganii blade described in the utility model is tapered in drill bit segment, and described cone point angle is 140 °.
Drill bit segment described in the utility model with between changeover portion for circular arc chamfering is connected.
Changeover portion described in the utility model with between the section of finish reaming for circular arc chamfering is connected.
The section of finish reaming described in the utility model with between knife bar for chamfering is connected.
There is the conical bore of diameter 3mm at knife bar tail end face center described in the utility model.
The utility model discloses a kind of high efficiency, high life drilling reamer structure, its multi-segment structure makes drilling reamer need not tool changing when processing through hole, reduce the usage quantity of cutter, avoid the tool changing of much knives tool and add the error produced by the factor such as lathe, handle of a knife man-hour, improve the precision of machining hole, improve the quality of product; Simultaneously because cutter structure improves cutter life, put into production, effectively improve production efficiency.Relative to other Tool Design, the utility model possesses following advantage:
1, when tool dimension is qualified, start to obtaining qualified products the time minimum shortening 150%-200% produced from production debugging;
2, start production when tool dimension is qualified, improve more than production capacity 150%-200%.
The utility model can be used for for aluminum hardware processing through hole.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is front view of the present utility model;
Fig. 2 is the partial sectional view of changeover portion of the present utility model;
Fig. 3 is the partial sectional view of the section of finish reaming of the present utility model.
Detailed description of the invention
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characteristic in the utility model creation, can combination of interactions under the prerequisite of not conflicting conflict.
As shown in Figures 1 to 3, a kind of high efficiency, high life drilling reamer structure, comprise overall cylindrical cutter hub 1 and the knife bar 2 of drilling and reaming, the described cutter hub 1 that drills and reams comprises the Rhizoma Sparganii blade arranged vertically for a pair, described Rhizoma Sparganii blade comprises drill bit segment 11, changeover portion 12, the section of finish reaming 13, the diameter of described drill bit segment 11 is less than the diameter of changeover portion 12, and the diameter of described changeover portion 12 is less than the diameter of the section of finish reaming 13, described in the diameter of the section of finish reaming 13 be less than the diameter of knife bar 2.Described drill bit segment 11, changeover portion 12, the section of finish reaming 13 are progressive, thus make in process without the need to tool changing, can directly time processing realize boring, reaming, finish ream shaping, avoid repeatedly tool changing to waste debug time, also there will not be because the difference tool axis that drills and reams is not aimed at and the problem such as cutter, breaking of shaking simultaneously.
