Description
Technical field
The utility model relates to mechanical drilling techniques fields, and in particular to cold drilling reamer in one kind.
Background technique
In field of machining, when processing inner hole, usually all it is first to carry out the roughing operation such as drill, reuses reamer
Fraising finishing, such procedure of processing are carried out to the hole being drilled, the hole surface mass deviation that conventional drill processes can not
Meet the processing of high requirement, so will increase this technique of reamer if necessary, not only increases the cost of charp tool, and increase
Process time needs frequent replacement cutters, and working efficiency is lower, lavishes labor on, the time, and again to knife calibration
Error can be generated in the process, influence the precision for processing inner hole.
Utility model content
The purpose of this utility model is that aiming at the shortcomings in the prior art, and cold drilling reamer in one kind is provided, have
The characteristics of drilling quality is high, low in cost and long service life.
The purpose of this utility model is achieved through the following technical solutions:
Cold drilling reamer in one kind, including cutter hub and knife handle, one end of knife handle are equipped with a rake, and rake connects cutter hub,
Cutter hub and knife handle are coaxially disposed；Cutter hub is equipped with spiral and drills and reams portion, and the spiral portion of drilling and reaming includes main cutting edge and is set to the master and cuts
Cut the ream portion on the outside of sword；Interior cold drilling reamer is additionally provided with interior cold hole, and cutter hub and knife handle are run through in interior cold hole.
Wherein, the cutter hub that spiral drills and reams between portion and the knife handle is additionally provided with the shaft shoulder.
Wherein, there are two interior cold holes.
Wherein, the diameter of main cutting edge is 4.1mm to 4.3mm.
Wherein, spiral drill and ream portion apex angle be 100 degree to 150 degree.
Wherein, the inclination angle of rake is 30 degree to 60 degree.
Wherein, the diameter of knife handle is 7mm to 9mm.
Wherein, the cylindricity of knife handle is 0.005.
The utility model has the beneficial effects that
Cold drilling reamer in one kind of the utility model, cutter hub and knife handle are coaxially disposed；Cutter hub is equipped with spiral and drills and reams portion；It is interior cold
Drilling reamer is additionally provided with interior cold hole, and cutter hub and knife handle are run through in interior cold hole, and knife handle is set to cutter hub for installing the interior cold drilling reamer
The spiral portion of drilling and reaming carries out bore operation, since rotary drill hinge portion includes main cutting edge and the ream portion that is set on the outside of main cutting edge,
While main cutting edge carries out bore expanded hole, hole wall is further processed in ream portion, increases the surface smoothness in hole.It passes through
The interior cold hole for wearing cutter hub and knife handle is passed through for compressed air, oil or cutting fluid, plays cooling cutter and workpiece, and wash away chip,
Lubricating action can also be played, reduces cutting frictional force, particularly suitable for deep hole machining.
Detailed description of the invention
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1 is the overall structure diagram of cold drilling reamer in one kind of the utility model.
Fig. 2 is the structural schematic diagram of the cutter hub of cold drilling reamer in one kind of the utility model.
Fig. 3 is the schematic diagram in the end sword section of cold drilling reamer in one kind of the utility model.
Appended drawing reference of the Fig. 1 into Fig. 3:
Cutter hub 1, main cutting edge 11, ream portion 12, the shaft shoulder 13；
Knife handle 2；
Rake 3；
Interior cold hole 4.
Specific embodiment
The utility model is further described with the following Examples.
Cold drilling reamer in one kind of the utility model, as shown in Figure 1, including cutter hub 1 and knife handle 2, one end of knife handle 2 is equipped with
The rake 3 that one inclination angle is 40 degree, rake 3 connect cutter hub 1, and cutter hub 1 and knife handle 2 are coaxially disposed；Cutter hub 1 is equipped with auger
Hinge portion, the spiral portion of drilling and reaming include main cutting edge 11 and the ream portion 12 for being set to the outside of main cutting edge 11, main cutting edge 11 into
While row bore expanded hole, ream portion 12 device to hole can carry out further ream while main cutting edge 11 drills, and improve
The finish of internal surface of hole；Cutter hub 1 is additionally provided with the shaft shoulder 13, and the shaft shoulder 13 is located at spiral and drills and reams between portion and knife handle 2, and the one of the shaft shoulder 13
End connection rake 3, other end connection spiral drill and ream portion, and the diameter of the shaft shoulder 13 is slightly less than spiral and drills and reams portion, make from knife handle 2
Transition to cutter hub 1 is more smooth, also increases the rigidity of cutter hub 1, prevents the spiral portion of drilling and reaming from twisting when rotated vibration；
Interior cold drilling reamer is additionally provided with two interior cold holes 4 for running through cutter hub 1 and knife handle 2, and interior cold hole 4 is worn for compressed air, oil or cutting fluid
It crosses, plays cooling cutter and workpiece, and wash away chip, moreover it is possible to lubricating action is played, cutting frictional force is reduced, particularly suitable for
Deep hole machining.
Wherein, the diameter of main cutting edge 11 is 4.2mm, and the drill and ream apex angle in portion of spiral is 140 degree, and the diameter of knife handle 2 is
8mm, the cylindricity of knife handle 2 are 0.005.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
