Abstract
The utility model relates to a tapping tool bit of a car-coupler tapered-thread sleeve. The tapping tool bit is characterized in that the outer lateral side of the tapered-thread sleeve and a tapered positioning hole are clamped and positioned together; the tapping tool bit of the car-coupler tapered-thread sleeve comprises a fixing section and a machining section, three filing discharging grooves with the circumferential intervals of 120 degrees are formed in the positions, on the upper portion of the machining section, of the cutting blade portion of the machining section, and the lower portion of the machining section is tapered; double-edge openings vertically arrayed are formed in the bottom three cutting blades; the machining section is provided with twelve to eighteen cutting blades in the longitudinal direction. The tapping tool bit special for the car-coupler tapered-thread sleeve is designed, and a shell of the car-coupler tapered-thread sleeve is tapered and arranged in a tapered hole for firm and accurate positioning; because the three filing discharging grooves are formed in the machining section of the too bit, filings can be more smoothly discharged; because the number of the cutting blades is increased, the feeding speed can be easily increased, and machining efficiency is improved; the bottom three cutting blades are automatically repaired in the reverse receding process, and therefore machining efficiency is further improved.
Description
Technical field
The utility model relates to a kind of tapping cutter head, specifically, is a kind of automobile tow hook tapered thread cover tapping cutter head, belongs to machine tool technical field.
Background technology
On the vehicle body of automobile front/rear collision bumper inner side, generally need towing hook thread bush of each fixed installation, the effect of this towing hook thread bush is in the time of running car, to break down cannot continue to travel time, need trailer to draw it, now, trailer hitch is installed and coordinated with thread bush, realize trailer and the effect for the treatment of that towing motorcar is connected.
The general structure of car puller hook thread bush comprises an assembling binding face, and tapered cover body, has screwed hole, for installation provision in it.
In prior art, this tapered thread cover is carried out to tapping and add man-hour, Milling Speed is slow, and efficiency is lower; Cutting face is more coarse, easily scratches surface of the work; Stability is low, and chip removal has some setbacks; The cutter head life-span is short, and single workpiece processing cost is high.
Summary of the invention
The utility model technical issues that need to address are: in prior art, this tapered thread cover is carried out to tapping and add man-hour, Milling Speed is slow, and efficiency is lower; Cutting face is more coarse, easily scratches surface of the work; Stability is low, and chip removal has some setbacks; The cutter head life-span is short, and single workpiece processing cost is high.
The utility model is taked following technical scheme:
A kind of automobile tow hook tapered thread cover tapping cutter head, lateral surface and the taper locating hole clamping and positioning of described tapered thread cover; Described automobile tow hook tapered thread cover tapping cutter head comprises canned paragraph and processing sections, and the cutting edge position of described processing sections and top thereof are provided with three chip areas 1, and described chip area 1 is circumferentially separated by 120 °; The bottom of described processing sections is tapered; Three cutting edges of described processing sections foot have double blade setting up and down; Described processing sections is longitudinally provided with 12-18 bar cutting edge; Described processing sections has hard metal coating.
The feature of the technical program is: for automobile tow hook tapered thread Analysis of Nested Design special tapping cutter head, the shell of Automotive Drawbar tapered thread cover is tapered, be arranged in bellmouth and position, contrast locating firmly, accurately, on the processing sections of cutter head, offer three chip areas, chip removal is more smooth and easy; Thereby increase cutting edge quantity and can easily improve feed speed, improved working (machining) efficiency; When reversion withdrawing, three cutting edges of foot are realized and automatically being repaired a die, improved working (machining) efficiency.
Described processing sections is longitudinally provided with 15 cutting edges.
The cutting edge partial-length of described processing sections is 37.8mm.
Described automobile tow hook tapered thread cover tapping cutter head total length is 96.79mm.
The beneficial effects of the utility model are:
1) processing high efficiency.In large batch of screw thread processing, due to the lower cutting speed restriction of screw tap and at the reversion withdrawing processing after screw thread, want to improve working (machining) efficiency very difficult.But this screw tap, not only Milling Speed itself is just very high for it, thereby and the design of its multitool groove increased cutting edge number and can easily improve feed speed, so just can significantly improve working (machining) efficiency.
2) excellent surface quality and dimensional accuracy.Add man-hour with this screw tap, very high cutting speed, less cutting force makes cutting face very smooth; The smear metal in small, broken bits liquid that can be cooled is easily gone out workpiece and can not scratched machined surface.
3) good stability, safe and reliable.
Ambassador's screw tap is not through fractureing in part for cutting force, and chip removal is smooth and easy.Smear metal can not be wound around screw tap or stop up aperture.Even just in case there is breaking, can not damage frock yet.
4) processing cost is low.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further illustrated.
Referring to Fig. 1-5, a kind of automobile tow hook tapered thread cover tapping cutter head, lateral surface and the taper locating hole clamping and positioning of described tapered thread cover; Described automobile tow hook tapered thread cover tapping cutter head comprises canned paragraph and processing sections, and the cutting edge position of described processing sections and top thereof are provided with three chip areas 1, and described chip area 1 is circumferentially separated by 120 °; The bottom of described processing sections is tapered; Three cutting edges of described processing sections foot have double blade setting up and down; Described processing sections is longitudinally provided with 12-18 bar cutting edge; Described processing sections has hard metal coating.
Described processing sections is longitudinally provided with 15 cutting edges.
The cutting edge partial-length of described processing sections is 37.8mm.
