Abstract
The utility model belongs to the field of cutting tools, in particular to a thread milling cutter. The thread milling cutter comprises a tool handle, a tool neck and a tool head. Two ends of the tool neck are respectively connected with the tool handle and the tool head, threaded blades are arranged on the circumferential face of the tool head, and the tool handle, the tool neck and the tool head are arranged integrally. A cooling liquid channel is arranged inside the center of the tool handle, the tool neck and the tool head, and a cooling liquid discharge hole is formed in the tool head and is connected with the cooling liquid channel. The thread milling cutter has the advantages that due to the cooling liquid channel arranged in the center of the tool handle, the tool neck and the tool head, and the cooling liquid discharge hole, the thread milling cutter is capable of performing the cooling function in time during the process of milling a thread hole, and prolonging the service life of a thread milling cutter.
Description
Technical field
The utility model belongs to the cutting tool field, specifically a kind of screw cutter.
Background technology
The structure of various cutters all is comprised of clamping part and working portion.Clamping part and the working portion of overall structure cutter all are made on the cutter hub; The working portion of inserted structure cutter (cutter tooth or blade) then is installed on the cutter hub.The clamping of cutter partly has with holes and band handle two classes.Rely on inner hole sleeve to be contained on the main shaft or axle of lathe with spot facing cutter, transmit torsional moment by axial bond or straight end-face key, such as cylindrical milling cutter, facing-type cutter etc.With the cutter of handle three kinds of rectangular shank, cylindrical handle and circular cone handles are arranged usually.Lathe tool, planing tool etc. are generally rectangular shank; The circular cone handle leans on the tapering bearing axial pushing force, and by the frictional force transmitting torque; Cylindrical handle generally is applicable to the cutters such as less fluted drill, slotting cutter, and the frictional force that produces when clamping during cutting is transmitted torsional moment.Much make with low-alloy steel with the shank of the cutter of handle, working portion then forms two parts butt welding with high-speed steel.The working portion of cutter is exactly the part that produces and process smear metal, comprises blade, makes smear metal structure, chip removal or appearance disconnected broken or that wind up store up the space of smear metal, the structural elements such as passage of cutting fluid.The working portion of the cutter that has is exactly cutting tip, such as lathe tool, planing tool, boring cutter and milling cutter etc.; The working portion of the cutter that has then comprises cutting tip and calibrated section, such as drill bit, reamer, reamer, inner surface broaching tool and screw tap etc.The effect of cutting tip is to excise smear metal with blade, and the effect of calibrated section is finished surface and the guiding cutter that smoothing has been cut.
Summary of the invention
The purpose of this utility model provides a kind of screw cutter for machining internal thread.
The utility model provides following technical scheme:
Screw cutter, it comprises handle of a knife, cutter neck and cutter head, cutter neck two ends connect respectively handle of a knife and cutter head, described cutter head side face is provided with the screw thread sword, handle of a knife, cutter neck, cutter head are integrated setting, and they are provided with cooling passage in the center, and cutter head is provided with cooling fluid and portals and be connected with cooling passage.
