Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Fig. 1 is broaching tool dish structure schematic diagram, and cutter tooth 4 is assemblied on broaching tool disk 5, has skewed slot, cutter tooth 4 to be embedded on broaching tool disk 5
In skewed slot, and it is fixed on broaching tool disk 5 by screw 6, broaching tool disk 5 is equipped with guide post 7,
Fig. 2 is the structural schematic diagram that broaching tool disk is combined into broaching tool, and broaching tool is integrally made of multiple broaching tool disks 5, is drawn herein with six
For cutterhead 5, wherein a, c, e cutterheads are one group, b, d, and f cutterheads are one group.It is provided with thrust bearing 8 between each cutterhead, with
Reduce frictional resistance when rotation,
Fig. 3 is outer locating sleeve structure schematic diagram, and two pairs of guide grooves 91, one pair of which A are machined on the outer positioning sleeve of broaching tool disk 9
Slot is spaced 180 degree.Another pair is B slots, and interval is all 180 degree.It is divided into lead-in groove 92, work nest 93 and export slot 94 per bar groove
