Technical field
The utility model relates to cutting-tool engineering fields, and in particular to a kind of left-right rotary combination rose reamer.
Background technique
Rose reamer, the more common a kind of machining tool arrived of field of machining at present, be assemblied in milling machine, drilling machine, planer,
For 60 degree of workpieces processing or 90 degree of chamferings and taper hole, reverse mould corner angle cutter on the lathes such as beveler, belong to slotting cutter.
Rose reamer is also chamfering device, and rose reamer is applied widely, is suitble to the chamfering of standard machinery workpiece, can be with rounding hole and the abnormity that falls
Side.Single-blade rose reamer, three sword rose reamers and circular hole rose reamer can be divided into according to sword number；60 degree, 90 can be divided into according to degree
Degree and 120 degree of rose reamers.
The shortcomings that conventional rose reamer, is: chamfering at top surface edge, milling lower surface can only be processed after work piece clamping
Shi Chongxin tool changing processing；It needs to bias certain angle, machining accuracy and processing efficiency to workpiece or by rose reamer if not tool changing
It is greatly affected.Conventional rose reamer, because CNC process tool under normal conditions fix by vertical clamping, cutting-tool angle, if to workpiece
It will affect machining accuracy and speed with tool offset angle；Therefore problem above can be generated.
Dovetail knife is similar to one kind of T-type knife, and the advantage compared to conventional rose reamer is not clamping workpiece again, can be right
Workpiece lower surface is processed.But dovetail knife also has its disadvantage: can only process at lower surface edge after a work piece clamping
Chamfering, tool changing is processed again when milling upper surface；It is needed if not tool changing to workpiece or dovetail knife is biased into certain angle or is incited somebody to action
Workpiece clamping again, is easy to produce the manufacturing deficiencies such as burr, machining accuracy and processing efficiency are greatly affected.Dovetail knife exists
CNC machining center is also vertical clamping, and since dovetail nose angle degree is fixed, design structure limitation leads to not simultaneously to falling up and down
Angle is processed.

In place with time processing, reduce the time of cutter tool changing, reduce the loss of significance repeated to knife.In addition, also compensating for repetition
The defect of clamping cutter bring dimensional accuracy loss, guarantees small size, high-precision, high efficiency, best bright finish chamfer machining.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of left-right rotary combination rose reamer, including the first cutting edge, empty avoiding portion, the second cutting edge and knife handle, described first
Cutting edge is connect by the empty avoiding portion with second cutting edge, and the knife handle is connect with second cutting edge, and described
One cutting edge and second cutting edge are helical structure, and their hand of spiral is opposite.
As a kind of improvement of left-right rotary described in the utility model combination rose reamer, first cutting edge is provided with the
One chip pocket, second cutting edge are provided with the second chip pocket, and first chip pocket is L shape straight trough, and described second holds
Bits slot is helicla flute.
As a kind of improvement of left-right rotary described in the utility model combination rose reamer, first cutting edge is provided with four
The end face of a end face sword, four end face swords is in a plane.
As a kind of improvement of left-right rotary described in the utility model combination rose reamer, first cutting edge is left-hand screw
Structure, second cutting edge are right-hand screw structure.
As a kind of improvement of left-right rotary described in the utility model combination rose reamer, first cutting edge and described the
The diameter of one cutting edge is all larger than the diameter in the empty avoiding portion.
The utility model has the beneficial effects that: the utility model include the first cutting edge, empty avoiding portion, the second cutting edge and
Knife handle, first cutting edge are connect by the empty avoiding portion with second cutting edge, the knife handle and second cutting
Sword connection, first cutting edge and second cutting edge are helical structure, and their hand of spiral is opposite.Due to upper
The setting of structure is stated, so that the rose reamer of the utility model, which compensates for existing cutter once, can only process lacking for a workpiece surface
It falls into, the time of cutter tool changing can be reduced with time processing in place when the multiple edges of workpiece need to process, reduce and repeat to knife
Loss of significance.In addition, also compensating for the defect of repeated clamping cutter bring dimensional accuracy loss, guarantee small size, high-precision
Degree, high efficiency, best bright finish chamfer machining.
