The detachable chamfering flat-end milling cutter comprises a cutter handle, a cutter neck, a cutter bit and a chamfering cutter, wherein the cutter handle, the cutter neck and the cutter bit are arranged integrally; the peripheral surface of the cutter bit is provided with a milling cutter edge; the outer peripheral surface of the cutter neck is provided with an external thread; the chamfering cutter is provided with a central hole; the inner peripheral surface of the central hole is provided with an internal thread adaptive to the external thread of the cutter neck; the milling cutter and the chamfering cutter are combined integrally, and the chamfering cutter can be detached.

Description

Detachable chamfering flat-end cutter
Technical field
The present invention relates to cutting-tool engineering field, particularly detachable chamfering flat-end cutter.
Background technology
Flat-end cutter is a kind of for Milling Process, the rotary cutter with one or more cutter tooth, and milling cutter operationally each cutter tooth cuts the surplus of workpiece successively off and on, cuts workpiece.In flat-end cutter is mainly used in working on milling machine, cut in the horizontal direction, cut the object on same plane, some can the thin burnishing surface of finish-milling (relative to sheer face) little chamfering, but the function of chamfering is complete not, the chamfering of some sheer face cannot milling, also need to change special rose reamer, just passable, which increase tool change time, service time is more, and production efficiency is lower.
Summary of the invention
The object of this invention is to provide a kind of milling cutter, rose reamer is combined into one, and the dismountable detachable chamfering flat-end cutter of rose reamer.
Realize technical scheme of the present invention as follows: detachable chamfering flat-end cutter, comprise handle of a knife, cutter neck, cutter head and rose reamer, described handle of a knife, cutter neck, cutter head is integrated setting, and described cutter head side face is provided with milling blade, and described cutter neck outer peripheral face is provided with external screw thread, described rose reamer is provided with centre bore, and the inner peripheral surface of centre bore is provided with the internal thread suitable with cutter neck external screw thread.
Described external screw thread radical length is greater than internal thread radical length.
Described external screw thread is provided with the nut with its adaptation.
The invention has the beneficial effects as follows: by cutter neck outer peripheral face is provided with external screw thread, described rose reamer is provided with centre bore, the inner peripheral surface of center sky is provided with the internal thread suitable with cutter neck external screw thread, after milling around workpiece one is enclosed by milling blade, the rose reamer that can also be provided with by cutter neck carries out chamfering to workpiece, carrying out chamfering with regard to not needing to change rose reamer like this, saving tool change time, enhancing productivity; Because external screw thread radical length is greater than internal thread radical length, when the position of chamfering is too high, the height of rose reamer can be regulated by longer external screw thread, realize chamfering; Arrange due to external screw thread with the nut of its adaptation, this nut can adopt upper and lower two, and what realize rose reamer upper and lower position is spacing.
Accompanying drawing explanation
Fig. 1 is the structural representation after the present invention combines;
Fig. 2 is the structural representation that the present invention decomposes rear flat-end cutter;
Fig. 3 is that the present invention decomposes rear rose reamer cross-sectional view;
Fig. 4 is that the present invention decomposes back nut cross-sectional view;
In accompanying drawing, 1 is handle of a knife, and 2 is cutter neck, and 3 is cutter head, and 4 is rose reamer; 5 is edge of milling cutter; 6 is external screw thread, and 7 is internal thread, and centered by 8 hole, and 9 is nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described;
Shown in Figure 1, comprise handle of a knife 1, cutter neck 2, cutter head 3 and rose reamer 4, described handle of a knife, cutter neck, cutter head is integrated setting, and described cutter head side face is provided with milling blade 5, and described cutter neck outer peripheral face is provided with external screw thread 6, described rose reamer is provided with centre bore 8, and the inner peripheral surface of centre bore is provided with the internal thread 7 suitable with cutter neck external screw thread.By this structure after milling around workpiece one is enclosed by milling blade, the rose reamer that can also be provided with by cutter neck carries out chamfering to workpiece, carries out chamfering like this with regard to not needing to change rose reamer.
Be greater than internal thread 7 radical length by external screw thread 6 radical length, when the position of chamfering is too high, the height of rose reamer can be regulated by longer external screw thread, realize chamfering.
External screw thread 6 is provided with the nut 9 with its adaptation, and this nut can adopt upper and lower two, and what realize rose reamer upper and lower position is spacing.
During assembling, first first nut is fixedly connected with cutter neck by external screw thread, regulates first nut to specified altitude assignment; Reinstall rose reamer, regulate height; Reinstall second nut.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
