The combination type milling cutter of reparation problem is difficult to after high and abrasion.
The technical scheme is that：
A kind of combination type milling cutter, it is made up of side tool disk, edge bearing, cutter shaft, circular knife, square blade and middle cutterhead；Its feature exists
In：Side tool disk is set with by flat key symmetry shape on cutter shaft；Multiple edge bearings are fitted with each side tool disk in diverging；The one of edge bearing
End extends to side tool disk inner side；Extend to the edge bearing termination on the inside of side tool disk and be fixed with multiple circular knifes；Described side tool disk it
Between be set with multiple middle cutterheads；Multiple cutters tooth are evenly equipped with the periphery of each middle cutterhead；The side's of being fixed with blade on each cutter tooth；
The cross-shaped installation on middle cutterhead of each side's blade；Square blade on each side's blade and adjacent middle cutterhead is in dislocation shape peace
Dress.
Square blade one end on described middle cutterhead extends to cutter tooth outer end；On the square blade other end and same periphery
Adjacent square blade has portion to overlap.
Described each side's blade and the curved projection surfaces of each circular knife is corresponding with work pieces process curved surface.
Described edge bearing is cuboid, and one end of edge bearing is provided with fastening journal stirrup；Edge bearing is by clamping screw through fastening
It is fixedly connected with side tool disk after journal stirrup；The other end of edge bearing is fixed with circular knife by arc installing port；The side of edge bearing is arranged
There is guide groove；Pressing plate is slidably connected in guide groove；Pressing plate is threadedly coupled by hold-down bolt with side tool disk.
It is an advantage of the current invention that：
The combination type milling cutter simple structure, design are ingenious；Employ using the intertwining position shape installation side blade of intermediate knife and use knife
Pad installs the structure design of circular knife；And the curved projection surfaces of each side's blade and each circular knife are corresponding with work pieces process curved surface；Adopt
After with this kind of design, each side's blade and circular knife can mutually stagger and complete machining, disperse cutting stress, and serving prevents
Lathe shakes excessive problem when cutting stress is concentrated.And each side's blade and circular knife and miscellaneous part can individually add
Work, it is individually replaced, and then solves that the cutting vibrations having when carrying out Machining of Curved Surface using existing profile milling cutter are serious, make week
The problem for being difficult to repair after phase length, high cost and abrasion, meets the needs of enterprise's production and application.

Specific embodiment
The combination type milling cutter, it is made up of side tool disk 1, edge bearing 2, cutter shaft 3, circular knife 4, square blade 5 and middle cutterhead 6：
Side tool disk 1 is set with by flat key symmetry shape on cutter shaft 3；Multiple edge bearings 2 are fitted with each side tool disk 1 in diverging；Edge bearing 2 is
Cuboid, one end of edge bearing 2 is provided with fastening journal stirrup 8；Edge bearing 2 by clamping screw 9 through fastening journal stirrup 8 after with side tool disk 1
It is fixedly connected；The other end of edge bearing 2 extends to the inner side of side tool disk 1；The termination of edge bearing 2 for extending to the inner side of side tool disk 1 passes through arc
Installing port 10 is fixed with multiple circular knifes 4.The purpose for being fixedly mounted with circular knife 4 by arc installing port 10 is：Limit circular knife 4
Installation site, qualified cambered surface is cut in order to it in side surface of workpiece.
The side of edge bearing 2 is provided with guide groove 11；Pressing plate 12 is slidably connected in guide groove 11；Pressing plate 12 passes through hold-down bolt 13
It is threadedly coupled with side tool disk 1.After edge bearing 2 is using this kind of design；Side tool can be fixed in from horizontal direction and in the radial direction
