Description
Technical field
The utility model relates to workpiece processing technology more particularly to a kind of cutters of workpieces processing.
Background technique
Currently, being usually that the surface roughness of workpiece is made to meet minimum requirements when being processed using cutter to workpiece.
But the assembly chamfer surface in some workpiece, such as workpiece 01 as shown in Figure 1, to meet matching requirements, the workpiece 01
The roughness in assembly chamfer face 011 must be within the scope of Rz6~Rz20.And existing process tool 02 as shown in Figure 2 is just
Rough surface RZ0.8~the Rz3.2 often processed, and there are big drift angles for the side knife surface of rose reamer 021 in process tool 02, therefore,
When being processed using process tool 02 to the assembly chamfer face 011 on workpiece 01, both it is bad control assembly chamfer face ruler
It is very little, there are the roughness requirements for being unable to satisfy assembly chamfer face.In addition, the point of a knife of the rose reamer of process tool 02 is excessively sharp, it is easy to wear,
And then cause the service life of process tool 02 short.
Utility model content
The processing request of the surface roughness in the assembly chamfer face of workpiece is unable to satisfy for the existing process tool of solution, this
Utility model proposes a kind of cutter, which includes knife bar and knife handle, and the knife bar is collinearly connect with the knife handle, the knife bar
Free end on be provided with drill, the side knife surface chamfering parallel with the center line axis of the knife bar is provided in the middle part of the knife bar
Knife and burnishing-in rose reamer, and burnishing-in sword is provided on the side knife surface of the burnishing-in rose reamer.Using the utility model cutter pair
When assembly chamfer face on workpiece is processed, guarantees the size in the assembly chamfer face that processing is formed using rose reamer, avoid
There is deviation in the size in assembly chamfer face, influences to assemble effect；Assembly chamfer face is controlled using the burnishing-in sword on laser rose reamer
Surface roughness, make processing formed assembly chamfer face surface roughness be in assembly needed for range in, with meet dress
With demand.
Preferably, the extending direction of the burnishing-in sword is vertical with the rake face of the burnishing-in rose reamer.Further, described
Two blade surface angle αs of burnishing-in sword are 120 °.In this way, being carried out using the utility model cutter to the assembly chamfer face on workpiece
When processing, it can avoid cutter and easily worn because the drift angle of rose reamer and burnishing-in rose reamer is excessive, to extend the use longevity of cutter
Life.
Preferably, there are two the rose reamer and two burnishing-in rose reamers for the middle part setting of the knife bar.Further
Ground, the rose reamer and the burnishing-in rose reamer are interspersed on the same circumference of the knife bar.It is further preferred that two
The rose reamer is symmetrical set, and two burnishing-in rose reamers are symmetrical set.In this way, can further improve the assembly of workpiece
The stability of the processing dimension of fillet surface and the stability of surface roughness.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of workpiece to be processed；
Fig. 2 is the structural schematic diagram of existing process tool；
Fig. 3 is the structural schematic diagram of the utility model cutter；
Fig. 4 is the structural schematic diagram of the burnishing-in rose reamer in Fig. 3.
Specific embodiment
In the following, the utility model cutter is described in detail in conjunction with Fig. 3 and 4.
As shown in figure 3, the utility model cutter includes knife bar 1 and knife handle 2, wherein knife bar 1 is collinearly connect with knife handle 2, knife
Drill 11 is provided on the free end of bar 1, the middle part of knife bar 1 is provided with rose reamer 12 and burnishing-in rose reamer 13, and rose reamer 12
Side knife surface 121 and burnishing-in rose reamer 13 side knife surface 131 it is parallel with the center line axis of knife bar 1, and burnishing-in rose reamer 13
Burnishing-in sword 132 is provided on side knife surface 131.Preferably, rose reamer 12 and burnishing-in rose reamer 13 are close to the free end of knife bar 1.It is excellent
Selection of land, as shown in figure 4, the extending direction of burnishing-in sword 132 is vertical with the rake face 133 of burnishing-in rose reamer 13.Preferably, burnishing-in sword
Blade surface angle α between 132 two blade surfaces 1321 is 120 °.In this way, in use the utility model cutter to the dress on workpiece
When being processed with fillet surface, it can avoid cutter and easily worn because the drift angle of rose reamer and burnishing-in rose reamer is excessive, to extend
Cutting-tool's used life.Preferably, rose reamer 12 and two burnishing-in rose reamers 13 there are two the middle part settings of knife bar 1, and chamfering
Knife 12 and burnishing-in rose reamer 13 are interspersed on the same circumference of knife bar 1.Preferably, two rose reamers 12 are symmetrical set,
Two burnishing-in rose reamers 13 are symmetrical set, and adjacent rose reamer 12 and burnishing-in rose reamer 13.In this way, can further improve work
The stability of the processing dimension in the assembly chamfer face of part and the stability of surface roughness.
When processing the assembly chamfer face on workpiece using the utility model cutter, guarantee to add using rose reamer
The size in the assembly chamfer face that work is formed, avoids the size in assembly chamfer face from deviation occur, influences to assemble effect；It is fallen using laser
The surface roughness in the burnishing-in sword control assembly chamfer face on the knife of angle, makes to process at the surface roughness in the assembly chamfer face formed
In range needed for assembly, to meet assembly demand.
