Wherein, 1-connecting rod, 2-cutter head, 4-front cutting edge; The right blade of 5-, 6-left side blade, 7-boss, the cutting edge of the right blade of 8-; The cutting edge of 9-left side blade, the plane that the cutting edge of the right blade of 10-keeps left, the plane that the cutting edge of 11-left side blade is kept right, the plane after the cutting edge of 12-front cutting edge leans on; The 13-workpiece, 14-fore-and-aft direction groove, 15-left and right directions groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like Fig. 1-Fig. 5; In practical application; With the utility model is the two ends that cutter head 2 is installed in connecting rod 1; Cutter head 2 is provided with three blades, is respectively the front cutting edge 4, left blade 6 that is arranged in cutter head 2 lefts (below of Fig. 2 and Fig. 3) and the right blade 5 that is arranged in cutter head 2 right-hand (tops of Fig. 2 and Fig. 3) that are arranged in cutter head 2 the place aheads (left of Fig. 2 and Fig. 3); If the common plane of forming of the cutting edge of said three blades is the D plane of horizontal direction; Plane 12 after the cutting edge of front cutting edge 4 leans on is by the preceding angle that then is 20 ° with the D plane; The plane 11 that the cutting edge 9 of left side blade 6 is kept right is right by a left side to be 20 ° angle with the D plane; The plane 10 that the cutting edge 8 of right blade 5 keeps left is 20 ° angle, other angle beyond above-mentioned 20 degree angles also can be 20 ° between 10 °-30 ° by right and left and D plane.
As shown in Figure 3, the cutting edge 9 of left blade 6 and the cutting edge 8 of right blade 5 then all are 1.5 ° angle with positive fore-and-aft direction by preceding, also can be other angle between 1 °-2 ° beyond 1.5 °.
Like Fig. 3 and shown in Figure 4, be provided with the boss 7 of fore-and-aft direction between left blade 6 and the right blade 5, the cross section of boss 7 is the middle part near D plane, the left and right sides circular arc away from the D plane; The Plane intersects that the cutting edge 9 of the left side of boss 7 and left blade 6 is kept right forms first intersecting lens; The Plane intersects that the cutting edge 8 of the right side of boss 7 and right blade 5 keeps left forms second intersecting lens, and said first intersecting lens and plane, said second intersecting lens place are the bottom surface of boss 7; Distance between the bottom surface of boss 7 and boss 7 middle parts is the height of boss 7, and the distance between boss 7 middle parts and the D plane is the high by 1/2 of boss 7, also can be other ratio between the 1/3-2/3 except that 1/2.
