Description
Technical field
The utility model relates to the Machining Technology field, specifically is a kind of cutter that is used to process inside tapered thread.
Background technology
At mechanical processing industry, conventional inside tapered thread processing is that (a kind of cutter of processing inside tapered thread has many row's screw-type blades to employing typing screw tap, has multiple tracks chip removal groove vertically.This cutter also is the screw thread screw tap, and a kind of specification can only be processed a kind of screw thread) carry out tapping.Screw tap of the prior art is various in style; Different; But be columniform tubulose multiple tooth (screw thread) structure Design mostly; Not enough below the screw tap of this structure exists: 1, the screw tap of multiple tooth structure is the screw thread knife-edge and arranges in the shape of a spiral, adds to bear the radially effect of torsion and axial compressive force man-hour, and this requirement of strength to the screw tap cone material is quite high.2, the range accuracy of the screw tap of multiple tooth structure between the height that adds each tooth in man-hour and each tooth is directly connected to the dimensional accuracy of work piece, and this causes the manufacturing forming process difficulty of screw tap bigger.3, the peripheral inwall with processing parts of the cylindrical tube structure of screw tap its blade when carrying out tapping closely offsets; The scrap that produces during tapping can only be discharged through chip area on the screw tap cone; And the design of chip area has a lot of restrictions; The too wide or too dark intensity that all can have influence on screw tap also has the radian design also to be worthy of careful study very much, and this causes the design of screw tap and the difficulty of manufacturing further to strengthen.In sum, the multiple tooth screw tap of the cylindrical tube under the prior art is because of complex design, and difficulty of processing is big, and is high to the requirement of strength of screw tap itself, causes this screw tap to cost an arm and a leg, particularly the import screw tap; At the same time, screw tap adds extruding, the friction that receives smear metal man-hour, and fall short of service life, further improved the screw thread processing cost.The useful internal screw cutting tool of internal thread to big specification in the prior art directly carries out inner screw thread milling processing, but receives the structural limitations and the processing method relative complex of lathe tool, and production efficiency is not high, and part quality is unstable.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of cost low, simple in structure, the adaptable cutter that is used to process inside tapered thread.
For solving the problems of the technologies described above; The technical scheme that the utility model provides is: a kind of cutter that is used to process inside tapered thread; It comprises handle of a knife and cutter head; Cutter head is fixed on the handle of a knife, and cutter head is provided with a working cutting edge (being cutter head has only a cutting edge and part generation milling to be processed to move) when work, the tool point angle of said working cutting edge identical with form of thread angle to be processed (identical here be meant that above-mentioned two cross sectional shapes of angle on normal direction are identical).
After adopting above structure; The utlity model has following advantage: have only a cutting edge and part generation milling to be processed action on the cutter head, the creationary cutter that makes has become the monodentate cutter head of monodentate structure by the screw tap of traditional multiple tooth structure, and this monodentate cutter head is when work; Because it is identical that the tool point angle of said cutting edge and the normal direction at form of thread angle to be processed are cut shape; Accurate control through the machining center lathe can process standard compliant screw thread again, and to the inside tapered thread part of some foreign standard; Like NPTF inside tapered thread of Unite States Standard etc. excellent adaptability is arranged; And this monodentate cutter (carbide chip) can process high duty metal, and programming is simple, and most of enterprises of mechanical industry can be competent fully.In sum; The utility model relates to, and to be used to process the cutter intensity of inside tapered thread high, with low cost, simple to operate; Simultaneously because have only a cutting edge and part generation stock removal action to be processed; Whole cutter has happy burr and chip clearance all the time when milling and between the hole to be processed of part, easily chip removal, and mechanical loss is few, the friction of smear metal and part is few; Simultaneously, change through program parameter, a kind of cutter can be processed the plurality of specifications screw thread.Therefore the utility model method and cutter of being used for machining internal thread has that cutter structure is simple, processing cost is low and adaptable characteristics.
As preferably; Said cutter head is removable the connection with handle of a knife, also is provided with a plurality of subsequent use cutting edges on the cutter head, a plurality of backup cutting swords of this preference; Can be after the working cutting edge wearing and tearing be bad; Cutter head pulled down switch to the backup cutting sword then and work on, further improved operating efficiency, optimized production cost.
As preferably, the front end of handle of a knife is provided with the groove that is used to install cutter head, and the handle of a knife in the groove is provided with screwed hole, and cutter head is provided with through hole, and screw is locked in cutter head in the groove through through hole and screwed hole; This preference selects for use common carbon constructional quality steel to make handle of a knife, further reduces production costs; Simultaneously the front end of handle of a knife is provided with the detent that is used to install cutter head, and the position-limiting action of groove can prevent that cutter head from rotating, the stability the during work that improved cutter.
