In the same figure, 11 and 12 are nut runners 13
The double walls 14 and 15 constituting the housing (not shown) in which the double walls 11 and 12 are housed are fixed sockets that are rotatably supported by bearings 16 and 17 and protrude horizontally from the double walls 11 and 12, respectively. In the movable socket, both sockets 14 and 15 are alternately arranged at equal positions on the circumference as shown in FIG. 2, and one fixed socket 14 and one movable socket 15 form a pair.
The fixed socket 14 and movable socket 15 are
Nut fitting parts 18 and 19 with different inner diameter dimensions at the tips
It also has driven gears 20 and 21 at its rear end, respectively. Furthermore, the movable socket 15 is configured to be extendable and retractable by slidably spline fitting a cylindrical portion 23 having a flange 22 approximately in the center onto a rotating shaft portion 24, and to adjust the reference working position of the fixed socket 14. It is possible to protrude and retract by a predetermined distance with respect to a. Reference numeral 25 denotes a nut runner body housed in a housing in correspondence with a pair of sockets 14 and 15. An end of this nut runner body 25 is fixed to the inner wall 12, and a shaft portion 27 having a drive gear 26 is attached to the outer wall. 11 via a bearing 28, and the drive gear 26 is meshed with the driven gears 20, 21 of the fixed socket 14 and movable socket 15, respectively, and one nut runner body 25 Rotational force is applied to the pair of fixed sockets 14 and movable sockets 15 at the same time. Reference numeral 29 denotes a driving means for expanding and contracting the movable socket 15 in the axial direction.
A hydraulic cylinder 31 for moving the socket is attached and fixed to the socket 2 via a bracket 30, and a push rod 33 spline-fitted to the outer wall 11 is attached to the tip of the rod 32 of the hydraulic cylinder 31. A disk 35 having gripping claws 34 is mounted at equidistant positions on the circumference. Then, the gripping claws 34 of the disk 35 are fitted into the flanges 22 of each movable socket 15, and the movable sockets 15 are expanded and contracted all at once by the protruding and retracting motion of the rod 32 of the fluid pressure cylinder 31.
