PURPOSE:To obtain many indexings by providing multiple trains of the second indexing gears facing multiple trains of the first indexing gears on the lower side of an indexing table and positioning coupling members and controlling so that the other second indexing gears are lowered when one of the second indexing gears is lifted. CONSTITUTION:Indexing gears 10 and 11 with teeth numbers 96 and 60, for example, are concentrically fitted on the lower side of an indexing table 2, positioning coupling members 12 with the same teeth are fixed to a frame 1 at three uniformly divided positions on the outside of the indexing gear 10, likewise positioning coupling members 13 are fixed to the frame 1 on the inside of the indexing gear 11. An indexing gear 14 with the teeth number 96 is fixed to a circular piston 20 in the circular cylinder 18 of an indexing lifting/lowering device 16 to face the indexing gear 10 and the coupling member 12, and it is fixed to the circular piston 21 in a circular cylinder 19 to face the indexing gear 11 and the coupling member 13. The indexing gears 14 and 15 can be lifted or lowered and have the teeth numbers 96 and 60, 17 kinds of indexings in total can be used including 11 kinds for the teeth number 96 and 11 kinds for the teeth number 60 except the same kind. |
