Detailed description of the invention:
Embodiment: the following embodiment that utility model is described by particular specific embodiment, those skilled in the art can understand other advantages of the present utility model and effect easily by content disclosed in the present specification.
Indexable rack milling cutter dish is made up of cutter hub 1, outer shroud teeth cutter blade 2, inner circular tooth blade 3, center tooth blade 4 and pushing broach screw 5.Cutter hub 1 has ten middle level cutting teeths 105 and ten non-middle level cutting teeths 104, non-middle level cutting teeth 104 has the equal insert groove of two sizes, be respectively outer shroud serrated knife film trap and inner circular tooth insert groove, outer shroud teeth cutter blade slot is in tooth bar top, inner circular tooth insert groove is positioned at tooth bar root, respectively outer shroud teeth cutter blade 2 and inner circular tooth blade 3 are installed, two blades are LNE434-02 type blade, two blade plane are that 15 ° of inclinations angle are staggered, middle level cutting teeth 105 is opened larger-size center tooth insert groove and center tooth blade 4 is installed, the radius of center tooth blade 4 is between inner circular tooth blade 3 and outer shroud teeth cutter blade 2 radius, center tooth blade 4 is LNE446R01 type blade, three blade plane tilt staggered mutually, three blades are fixed by the M5 pushing broach screw 5 of specification of the same race, cutter hub 1 center has the centre bore installing turning cylinder, centre bore has the M6 screw that screwed hole 101 is arranged on fixation cutter head on tumbler up and down.
As shown in Figure 1, as the quenching degree that the material require high strength of cutter hub 1, high tenacity are become reconciled, and 42CrMo can meet above-mentioned requirements well, 42CrMo material is without obvious temper brittleness, and after fine finishining nitrogen treatment, have higher fatigue limit and anti-this impact capacities many, low-temperature impact toughness is good, is the material of outstanding rack milling cutter.
As shown in Figure 1, cutter hub 1 milling cutter card circumference has four little fabrication holes 102 and four large fabrication holes 103, and opening fabrication hole, to effectively reduce the quality of cutter hub 1 cost-saving, and eight fabrication holes are distributed on milling cutter card respectively, and technique angle of spot hole E is 90 °.
As shown in Figure 3 and Figure 4, the cutting teeth limit that outer shroud teeth cutter blade 2, inner circular tooth blade 3 and center tooth blade 4 are installed all has deep-slotted chip breaker, this is the chip area designed to ensure cutting swarf to discharge smoothly, the non-middle level cutting teeth 104 of cutter hub 1 is provided with outer shroud teeth cutter blade 2 and inner circular tooth blade 3, and and contiguous center tooth blade 4 interval nearer, the cutting swarf stayed after three's processing is discharged smoothly through respective chip area, can not influence each other.
As shown in Figure 1, outer shroud teeth cutter blade 2, inner circular tooth blade 3 and the interlaced arrangement of center tooth blade 4, but not have no to occur simultaneously, when manufacturing gear strip groove, outer shroud teeth cutter blade 2 pairs of tooth bar workpiece are rough milled for the first time, inner circular tooth blade 3 and center tooth blade 4 carry out secondary and rough mill, and namely have certain amount of lap between three, overlap joint is of a size of 1.2 ~ 2.5mm.
As shown in Figure 3 and Figure 4, the cutting angle F of outer shroud teeth cutter blade 2 is 8 °, and the cutting angle G of center tooth blade 4 is 8 °, and the equal and opposite in direction of the cutting angle of inner circular tooth blade 3 and the cutting angle F of outer shroud teeth cutter blade 2 is also 8 °.Large cutting angle can make blade bear less operating pressure, but too small cutting angle then may cause unstable machine cuts, in addition, when cutting speed is higher, the process heat produced can not be discharged from blade fully, cutter thus can be subject to very large thermal force.Take cutting angle to be that the cutter of 8 ° can reach best cutting effect, namely cutting force is little, and cutting edge is stablized, and weares and teares little.
Described embodiment in order to illustrative the utility model, but not for limiting the utility model.Any those skilled in the art all without prejudice under spirit of the present utility model and category, can modify to described embodiment, therefore rights protection scope of the present utility model, should listed by claim of the present utility model.
