The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 9 as can be known, the utility model is the upright dress of cutter tooth, and each cutter tooth on the milling cutter is staggered.
Shown in Figure 1 is that the utility model milling cutter molded lines cutter tooth constitutes total figure, and mark 1 is a milling cutter among the figure, and 2,3,4,5,6,7,8,9,10,11,12,13 is cutter tooth.The present embodiment is that all cutters tooth of this cutter all adopt overlapping mode to connect, and accurately constitutes the used molded lines of processing Nut column inner trapezoidal thread.The milling cutter position corresponding with Nut column inner trapezoidal thread bottom surface sections is made of 2 circular arc angle of throat teeth 10,11; With the corresponding milling cutter of Nut column inner trapezoidal thread angle faces position, constitute by the cutter tooth 2,3,4,5,6,7,8,9 of 8 identical straight land anterior angles, become the main cutting face of milling cutter; For preventing to interfere, the non-main cutting face of milling cutter is made of the cutter tooth 12,13 of 2 identical straight land anterior angles.Requiring milling cutter molded lines tolerance is ± 0.1; Angle tolerance is controlled at ± 2 ', this just needs accurately to arrange each cutter tooth, to guarantee the molded lines precision of milling cutter, guarantees that the molded lines of the Nut column inner trapezoidal thread that processes satisfies user's requirement.The molded lines of strict control milling cutter in the process of design, technology, programming, processing to guarantee the precision of milling cutter, guarantees that the molded lines of the Nut column inner trapezoidal thread that processes satisfies user's requirement.
Milling cutter cutter tooth shown in Figure 2 is arranged corresponding to 2,3,4,5,6,7,8,9,10,11,12,130 two cutters tooth of the mark among Fig. 1, constitute one group of effective tooth, cutter tooth 10,11 is taked angle modification, all the other cutters tooth are taked directly to change relief angle along the cutter tooth cutting edge, thereby guarantee the molded lines precision of milling cutter; Cutter tooth is staggered each other, reduces vibration, makes stable cutting, and milling cutter adopts the positive rake angle design, effectively reduces cutting resistance, and sign 15 is a screw, and each cutter tooth is fixed on the milling cutter 1 with a screw, and cutter tooth clamps by cutting force.
Milling cutter cutter tooth shown in Figure 3 is arranged corresponding to 2,3,4,5,6,7,8,9,10 9 cutters tooth of the mark among Fig. 1, constitutes one group of effective tooth, and cutter tooth is staggered each other, reduces vibration, makes stable cutting.Each cutter tooth is fixed on the milling cutter 1 with a screw 14, and cutter tooth clamps by cutting force.
