PURPOSE:To reduce the weight of a whole device and improve the continuity of each operation by arranging an outer shaft and an inner shaft in parallel to a countershaft and connecting the aforesaid shafts to one another via a plurality of cam mechanisms. CONSTITUTION:An outer shaft 47 of pipe shape is passed through a box 40 in parallel to a countershaft 45 and supported in such a way as to be free to turn and slide in an axial direction. The forward end of the shaft 47 is fitted with a chucking unit 41 and an inner shaft 48 is so inserted in the shaft 47 as to be free to turn and in such a way that both ends thereof project from the shaft 47. Also, cam mechanisms 49 and 50 are provided between shafts 45 and 47, and another cam mechanism 51 provided between shafts 45 and 48. The shaft 47 advances and retreats in an axial direction, thereby causing the shift of a unit 41 in a tool mounting and dismounting direction and the intermittent turn of the shaft 47. As a result, the unit 41 reverses between a machine tool and a tool magazine. Furthermore, the turn of the shaft 48 causes the advance and retreat of the finger of the unit 41 for the machine tool and the tool magazine. |
