Abstract
The utility model discloses a kind of plane circular arc one-pass molding knives, cutter head including being in cylindrical type, there is arc angling face between the front end surface and cylindrical type outer surface of cutter head, chip space there are four being uniformly arranged in the circumferential direction at the top of cutter head, a cutter groove is provided at the top of each chip space, a blade is mounted in each cutter groove, at least one first blade and at least one second blade in the blade, when cutter head rotates, first cutting edge and the second cutting edge respectively constitute the first cutting face and the second cutting face, the cutting face that first cutting face and the second cutting face are combined into is by the first plane perpendicular to cutter head axis, it is constituted with the first cylindrical surface of cutter head axis coaxle and the fillet surface for connecting the first plane and the first cylindrical surface.The beneficial effects of the utility model are: structure is simple, chip removal is convenient, clamped one time, time processing can complete the processing of hole slot of the slot bottom with chamfering, improve processing efficiency.
Description
Technical field
The utility model relates to be machined to use cutting-tool engineering field, especially a kind of plane circular arc one-pass molding knife.
Background technique
Existing machinery lathe for machining is when processing groove tail band has the hole slot of chamfering, it usually needs cutter or workpiece repeatedly turn over
Dynamic, multiple clamping, repeatedly processing could complete processing, and processing efficiency is low.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provides a kind of plane circular arc one-pass molding knife, and one
Secondary clamping, time processing can complete the processing of hole slot of the slot bottom with chamfering, improve processing efficiency.
The purpose of this utility model is achieved through the following technical solutions: a kind of plane circular arc one-pass molding knife, including is in
The cutter head of cylindrical type has arc angling face between the front end surface and cylindrical type outer surface of cutter head, the top of cutter head is circumferentially
It is uniformly arranged there are four chip space, is provided with a cutter groove at the top of each chip space, is mounted on one in each cutter groove
Blade, at least one first blade and at least one second blade, the first of first blade cut in the blade
It cuts sword to extend from the front end surface of cutter head to the arc angling face of cutter head rear side, and the first cutting edge exceeds the outer surface of cutter head,
Second cutting edge of second blade extends from the arc angling of cutter head towards the cylindrical type outer surface of cutter head, and second cuts
The outer surface that sword exceeds cutter head is cut, when cutter head rotates, the first cutting edge and the second cutting edge respectively constitute the first cutting face and the
Two cutting faces, the first cutting face smoothly connect or partially overlap with the second cutting face, and the first cutting face and the second cutting face group
The cutting face of synthesis be by perpendicular to cutter head axis the first plane, with the first cylindrical surface of cutter head axis coaxle and connect first
The fillet surface on plane and the first cylindrical surface is constituted.
During processing to the utility model, the cutting face that the first blade and the second blade are constituted can be completed at the same time
The processing of the fillet surface of slot bottom, cell wall and link slot bottom and cell wall.
The center of the cutter head has the connecting hole through cutter head.
The rear end of the cutter head has attachment base.
The utility model has the advantage that
The utility model structure is simple, chip removal is convenient, and clamped one time, time processing can complete the hole that slot bottom has chamfering
The processing of slot, improves processing efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic cross-sectional view of the utility model.
In figure, 1- cutter head, 2- arc angling face, 3- chip space, 4- cutter groove, the first blade of 5-, the second blade of 6-, 7- first
Cutting edge, the second cutting edge of 8-, 9- connecting hole, 10- attachment base.
Specific embodiment
The utility model is further described with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of plane circular arc one-pass molding knife, the cutter head 1 including being in cylindrical type, the front end of cutter head 1
There is arc angling face 2 between end face and cylindrical type outer surface, the top of cutter head 1 is uniformly arranged in the circumferential direction there are four chip space 3,
The top of each chip space 3 is provided with a cutter groove 4, is mounted on a blade in each cutter groove 4, in the blade extremely
Rare first blade 5 and at least one second blade 6, the first cutting edge 7 of first blade 5 is before cutter head 1
End end face is to extending on rear side of the arc angling face 2 of cutter head 1, and the first cutting edge 7 exceeds the outer surface of cutter head 1, and described second
Cylindrical type outer surface of second cutting edge 8 of blade 6 from the arc angling face 2 of cutter head 1 to cutter head 1 extends, and the second cutting edge 8
Outer surface beyond cutter head 1, when cutter head 1 rotates, the first cutting edge 7 and the second cutting edge 8 respectively constitute the first cutting face and the
Two cutting faces, the first cutting face smoothly connect or partially overlap with the second cutting face, and the first cutting face and the second cutting face group
The cutting face of synthesis be by perpendicular to 1 axis of cutter head the first plane, with the first cylindrical surface of 1 axis coaxle of cutter head and connect the
The fillet surface on one plane and the first cylindrical surface is constituted.
During processing to the utility model, the cutting face that the first blade 5 and the second blade 6 are constituted can be complete simultaneously
The processing of the fillet surface of grooving bottom, cell wall and link slot bottom and cell wall.
The center of the cutter head 1 has the connecting hole 9 through cutter head 1.
The rear end of the cutter head 1 has attachment base 10.
