Abstract
The invention relates to an inner bore grooving cutter which is an integrally formed structure. The inner bore grooving cutter comprises a cylindrical cutter handle, wherein a clamping plane is arranged on the cutter handle; an arc surface is milled on the front end of the cutter handle; the arc surface is crossed with an extending surface of a circular arc outside the cutter handle to form a transitional cutter bar with a similar oval sectional form; a cutting plane parallel to an axis of the cutter bar is milled on the front end of the transitional cutter bar; the cutting plane and an inclined section of the transitional cutter bar are enclosed to form a chip groove of the grooving cutter; a cutting edge is arranged on the top end of the transitional cutter bar; the front surface of the cutting edge is arranged on the cutting plane of the transitional cutter bar. The inner bore grooving cutter occupies little machining space and removes chips smoothly, and can machine inner threads with various thread pitches from 0.2mm to 10 mm or more; a relief angle of the threads is modified according to a spiral lifting angle for machining the threads, so that the cutter is ensured to be cut smoothly.
Description
Technical field
The present invention relates to a kind of internal thread cutter, particularly a kind of interior hole slot cutter.
Background technology
The common cutter that is used to process the nut inner groove is whole hard alloy screw cutter and frame blade type screw cutter, has 5-7 serrated knife point screw thread, can process at one time screw thread.The general work flow of multiple tooth screw cutter is; Be covered with screw thread processing tooth on the cutting edge of screw cutter; Three-shaft linkage through Digit Control Machine Tool; Utilize formed threading tool to carry out the spiral interpolation and form screw thread, cutter is processed along helix can accomplish screw thread processing a week, also can rotate more and reach the screw thread requirement degree of depth several weeks.Its shortcoming is that it is many that multiple tooth screw cutter takies processing space, and chip removal has some setbacks, and causes the wearing and tearing of cutter easily, reduces the service life of cutter, has also reduced the efficient of cutter machining screw simultaneously.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the object of the present invention is to provide a kind of chip removal and high interior hole slot cutter of working (machining) efficiency of making things convenient for.
The technical scheme that the present invention is adopted for the technical solution problem is following:
Hole slot cutter in a kind of, the structure that is formed in one, it has a cylinder handle of a knife; Handle of a knife is provided with one and adds fair face; Front end at handle of a knife is milled with a cambered surface, and the extended surface of said cambered surface and handle of a knife external arc intersects, and surrounding a section configuration is the transition knife bar of approximate ellipsoidal; The front end of transition knife bar be milled with one with the cutting plane of cutter spindle line parallel; The oblique section of said cutting plane and transition knife bar surrounds the chip area of groove cutter, and transition knife bar top is provided with a cutting edge, and the rake face of said cutting edge is on the cutting plane of transition knife bar.
Beneficial effect of the present invention is:
It is few that the monodentate screwer takies processing space, and chip removal is smooth and easy;
Monodentate screwer between cog pitch is fixing, can process from 0.2mm to 10mm more than the internal thread of various pitch, the relief angle according to the lead angle correction screw thread of machining screw guarantees that Tool in Cutting is smooth.
Description of drawings
Fig. 1 is the stereogram of hole slot cutter in the present invention.
Fig. 2 is the front view of hole slot cutter in the present invention.
Fig. 3 is the right view of hole slot cutter in the present invention.
The specific embodiment
Embodiment, by Fig. 1, Fig. 2, shown in Figure 3:
The interior hole slot cutter of present embodiment, the structure that is formed in one, it has a cylinder handle of a knife 1, mills out one on the handle of a knife 1 and adds the face 2 that maintains an equal level, so that adding that cutter can be more stable is held on the knife rest; Front end at handle of a knife is milled with a cambered surface 3; The extended surface 4 of said cambered surface and handle of a knife external arc intersects, and surrounding a section configuration is the transition knife bar of approximate ellipsoidal (opal shape), and the transition knife bar is thinner than handle of a knife; During operations; Knife bar gos deep in the hole, and the gap between itself and hole wall is bigger, so that the cutting chip is discharged smoothly; The front end of transition knife bar be milled with one with the cutting plane 5 of cutter spindle line parallel, the oblique section 6 of said cutting plane and transition knife bar surrounds the chip area of groove cutter, transition knife bar top is provided with a cutting edge 7, the rake face 8 of said cutting edge is on the cutting plane of transition knife bar.
It is few that the interior hole slot cutter of present embodiment takies processing space, and chip removal is smooth and easy, can process from 0.2mm to 10mm more than the internal thread of various pitch, the relief angle according to the lead angle correction screw thread of machining screw guarantees that Tool in Cutting is smooth.
