Abstract
The utility model relates to the technical field of cutters and in particular relates to a detachable chamfering flat-end milling cutter. The detachable chamfering flat-end milling cutter comprises a cutter handle, a cutter neck, a cutter head and a chamfering cutter, wherein the cutter handle, the cutter neck and the cutter head are integrally arranged; a milling blade is arranged at the periphery of the cutter head; an external thread is arranged at the periphery of the cutter neck; a central hole is formed in the chamfering cutter; and an inner thread, which is adaptive to the external thread of the cutter neck, is arranged on the inner circumference surface of the central hole. Through the detachable chamfering flat-end milling cutter, the milling cutter and the chamfering cutter are combined integrally; and the chamfering cutter is detachable.
Description
Technical field
The utility model relates to cutting-tool engineering field, particularly detachable chamfering flat-end cutter.
Background technology
Flat-end cutter be a kind of for Milling Process, there is the rotary cutter of one or more cutters tooth, milling cutter each cutter tooth in the time of work cuts the surplus of workpiece successively off and on, and workpiece is cut.In flat-end cutter is mainly used in working on milling machine, along continuous straight runs cuts, object on same plane is cut, and some can the little chamfering of the thin burnishing surface of finish-milling (with respect to sheer face), but the function of chamfering is complete not, the chamfering of some sheer face cannot milling, also need to change special rose reamer, just can, increased like this tool change time, service time is more, and production efficiency is lower.
Utility model content
The purpose of this utility model 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 the technical solution of the utility model 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, on 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 adaptive with it.
The beneficial effects of the utility model are: by being provided with external screw thread on cutter neck outer peripheral face, 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 blade encloses workpiece milling one around, the rose reamer that can also be provided with by cutter neck carries out chamfering to workpiece, carry out chamfering with regard to not needing to change rose reamer like this, saved tool change time, enhanced productivity; Because external screw thread radical length is greater than internal thread radical length, in the time that the position of chamfering is too high, can regulate by longer external screw thread the height of rose reamer, realize chamfering; Due to the nut adaptive with it that external screw thread arranges, this nut can adopt upper and lower two, and realization is spacing to rose reamer upper and lower position.
Accompanying drawing explanation
Fig. 1 is the structural representation after the utility model combination;
Fig. 2 is the structural representation of flat-end cutter after the utility model decomposes;
Fig. 3 is rose reamer cross-sectional view after the utility model decomposes;
Fig. 4 is that the utility model 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.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model 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, on 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 blade encloses workpiece milling one around, the rose reamer that can also be provided with by cutter neck carries out chamfering to workpiece, has carried out chamfering like this with regard to not needing to change rose reamer.
Be greater than internal thread 7 radical lengths by external screw thread 6 radical lengths, in the time that the position of chamfering is too high, can regulate by longer external screw thread the height of rose reamer, realize chamfering.
External screw thread 6 is provided with the nut adaptive with it 9, and this nut can adopt upper and lower two, and realization is spacing to rose reamer upper and lower position.
When 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 utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
