Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
Shown in referring to figures 1-3, the utility model provides a kind of cutting edge uneven distribution formula reamer, including knife bar 1
With cutter head 2, the cutter head 2 is connected to the head of knife bar 1；Cutter head 2 can be cylindrical or stepped.The cutter head 2 is equipped with
The cutting edge of six dextrorotation is followed successively by the first cutting edge 201, the second cutting edge 202, the along the circumferencial direction distribution of cutter head 2
Three cutting edges 203, the 4th cutting edge 204, the 5th cutting edge 205 and the 6th cutting edge 206；Wherein the first cutting edge 201, third
Cutting edge 203, the 4th cutting edge 204, the 5th cutting edge 205 include the first arc edge A and oblique blade B, the first circular arc
Cutting edge A and oblique blade B is continuously, for the inner hole refine to being processed；Second cutting edge 202 and the 6th cutting edge
206 be the second arc edge C, is used for workpieces processing inner hole.And second arc edge C and the first arc edge A be located at
On the circumference of same circle, the radian of the second arc edge C is greater than the radian of the first arc edge A, i.e. the second circular arc cutting
The central angle g of sword C is greater than the central angle i of the first arc edge A.
Using above technical scheme, six cutting edges of the cutter head 2, second cutting edge 202 and the 6th cutting edge
206 be the second arc edge C, the radius of the two the second arc edge C is identical as the internal bore radius of workpiece, for processing
