The specific embodiment

With reference to Fig. 1-3, the index plate drilling tool comprises base assembly 1, five equilibrium fluted disc 2 and the scroll chuck 5 that rotates with 2 interlocks of five equilibrium fluted disc; Said five equilibrium fluted disc 2 and the switching of base assembly 1 concentric, said base assembly 1 one sides are provided with the locking device 3 through branch fluted disc 2 rotations such as branch fluted disc 2 teeth groove such as blocking limit.

Base assembly 1 comprises base 10 and is installed on the central shaft 11 on the base 10 that said five equilibrium fluted disc 2 is transferred through bearing 13 concentrics with central shaft 11; Central shaft 11 tops are provided with the dust cap 12 that closely contacts with five equilibrium fluted disc 2 upper surfaces; Base 10 lower surfaces also are connected with base plate 14.

Be provided with the rolling mechanism that branch fluted disc 2 such as is used to keep horizontally rotate between base 10 upper surfaces and five equilibrium fluted disc 2 lower surfaces; Rolling mechanism comprises that the V-ring groove 101 of being located at base 10 upper surfaces, rectangle annular groove 22, the activity of being located on five equilibrium fluted disc 2 lower surfaces are inlaid in the ball 4 between V-ring groove 101 and the rectangle annular groove 22.

Locking device 3 comprises connecting plate 30, fairlead 31, pull bar 32 and fastening screw 33; Connecting plate 30 1 ends are fixed on the base 10; Fairlead 31 is fixed on the connecting plate 30; The switching of pull bar 32 bottoms is at connecting plate 30 other ends; Fastening screw 33 activities are installed in the fairlead 31, and the rear end of fastening screw 33 passes fairlead 31 and is hinged on the pull bar 32, are provided with in the fairlead 31 fastening screw 33 to the reseting pressuring spring 34 that waits branch fluted disc 2 radial elastics to compress.
