The utility model discloses simple structure, easy installation for processing tooth form top be the circular arc, and the bottom be sharp helicitic texture, the workable straight line of the root of thread cutting blade thread root that appears, and the workable convex top of thread of crest cutting blade, the increase cutting edge is used for constituting crest cutting blade's circular structure.
Description
[technical field]
The utility model relates to special lathe tool, particularly a kind of circular arc crest threading tool.
[background technology]
The tooth form top of regular screw threads is the flat-top not with circular arc, and the lathe tool processing these regular screw threads only has a cutting edge usually.And some specials are needed in some manufacture field, the crest as screw thread is other shapes such as circular arc, gradient, and above-mentioned regular screw threads lathe tool can not realize.
[utility model content]
The purpose of this utility model is to provide a kind of circular arc crest threading tool, and be circular arc for processing tooth form top, bottom is the helicitic texture of straight line.
For this reason, the utility model is by the following technical solutions:
A kind of circular arc crest threading tool, comprise cutter hub, cutter hub center is provided with installing hole, and described cutter hub side is provided with working face, it is characterized in that: described working face comprises cutting blade at the bottom of the tooth of a flat-top, the increase blade of the crest cutting blade of a circular arc and a circular arc.
Further, at the bottom of described tooth, the flat-top width of cutting blade is 0.131 ± 0.005mm, and tooth form cutting level is 0.474 ± 0.005mm, and tooth form cutting angle is 60 °; The radius of rounded crest of crest cutting blade is 0.1 ± 0.005mm, and crest arc angle is 60 °, and the horizontal range at the flat-top center of cutting blade at the bottom of crest center of arc to tooth is 0.397 ± 0.005mm; Increasing the top arc radius of blade is 0.1mm, and the top arc increasing blade is 0.12mm to the vertical range of crest circular arc, and the top arc center of increase blade is 0.18mm to the horizontal range of crest center of arc.
Further, the flat-top of cutting blade at the bottom of described tooth is 1.2mm to the maximum normal distance of the right cutting edge increasing blade, at the bottom of the flat-top center of cutting blade at the bottom of tooth to tooth, the maximum horizontal range of the left cutting edge of cutting blade is 0.60mm, and the flat-top center of cutting blade at the bottom of tooth is 1.13mm to the maximum horizontal range of the right cutting edge increasing blade.
Further, the relief angles of described working face is 5 °.
Further, described cutter hub is equilateral triangle straight cylinder.
Further, the thickness of described cutter hub is 3.2mm.
The utility model structure is simple, easily installs, and cutting blade at the bottom of tooth can processing linear shape Bottom of Thread, and crest cutting blade can Machining Arc shape thread crest, and increase blade for forming the arc structure of crest cutting blade, triangle cutter hub intensity is high.
