As shown in Figure 10, in pivotal process, there is certain superposition amount in positive chamfering blade 5, rough milling cutter blade 6, anti-chamfering blade 7; Because the inwall length of workpiece is much larger than blade lengths, so need three rough milling cutter blades about 6 to superpose use, superposition amount is 0.5mm, and the angle of positive chamfering blade 5 and anti-chamfering blade 7 is all identical with the chamfer angle of workpiece, is respectively 30 ° and 15 °.
The using method of the compound tool as described in embodiment two, compound tool described in embodiment two is arranged on numerical control machining center by blind rivet 1, cutter hub axis 14 is perpendicular to the ground, after workpiece to be processed is located and is clamped, start lathe, then lathe carry its tools rotates always, then cutter moves according to the numerical control program of artificial setting, processing action starts, the degree of depth that in process, cutter is downward reduces successively, by the motion in level and vertical both direction, by workpiece machined surface completion of processing, workpiece size is made to reach product figure drawing dimensional requirement.Its process is divided into four work steps, it is important to note that become in Finished product processThe from blank because of workpiece inner wall, allowance comparatively large (monolateral surplus is about 5mm), then complete processing successively by four work steps, specifically describe as follows:
Work step one: the outer face 10 of milling spindle cover installing hole 9, as shown in figure 11, in same depth plane, movement locus is circular, and see the direction of arrow, the blade of use is face-milling insert 8; Outer face completion of processing.
Work step two: the inwall 11 rough milling axle sleeve installing hole 9, as shown in figure 12, movement locus is straight line, and the direction of motion is always downward, and see the direction of arrow, the blade of use is face-milling insert 8; Irregular for inwall black skin is machined away, but still remains most allowance.
Work step three: the inwall 11 of milling spindle cover installing hole 9, positive chamfering 12 and instead angle 13, as shown in figure 13, in same depth plane, movement locus is circular, see the direction of arrow, the blade of positive chamfering blade 5, rough milling cutter blade 6, anti-chamfering blade 7 correspondence moves simultaneously and cuts; The inwall 11 of axle sleeve installing hole 9 is removed the processing capacity of a part, but still leave a small amount of allowance (0.25mm) to postorder; By positive chamfering 12 and instead angle 13 completion of processing while milling inwall 11.In order to be beneficial to understanding, show processing effect, Figure 14 is defined after rough milling cutter blade 6 and anti-chamfering blade 7 being rotated, and in order to show positive chamfering blade 5, rough milling cutter blade 6, the angle of anti-chamfering blade 7 on gyratory directions, define Figure 15, the angle on gyratory directions shown in Figure 15 is identical with the angle of several blade in orthographic projection.
Work step four: the inwall 11 of right boring axle sleeve installing hole 9, as shown in figure 16, movement locus is straight line, sees the direction of arrow, and the blade of use is right boring blade 3.Inwall is remained allowance all machine away, make inwall reach final size.
After four work step completion of processing, lathe carry its tools upwards exits workpiece, and cutter stops operating, and whole course of action is complete.
The technical scheme advantage of this compound tool is just, is namely achieved the processing of axle sleeve installing hole 9 all sites to knuckle, instead of in original scheme the mode utilizing four cutters to process one by one by a cutter; And by the special construction of blade installation site, make positive chamfering 12, instead angle 13, the processing of inwall 11 completes in a movement locus, greatly reduce number of cutters, substantially increase production efficiency.
Rough estimate, a set of knuckle axle sleeve installing hole use four is 240 seconds the machining time of cutter, and be often 10 seconds the tool change time of cutter, utilize the compound tool in the present embodiment can reduce by 3 exchanging knives processes, namely reducing tool change time is 10 × 3=30 second, such machining time becomes 240-30=210 second, and production efficiency improves 14.3%;
In addition, due to the reduction of tool category and quantity, the quantity backing up cutter is also reduced, like this, just greatly reduces purchase cost and maintaining cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
