According to the publication, a clamp member operated by a cylinder is provided in a machine frame into which a screw member can be inserted, and when the socket of the nut runner is rotated at a slow speed and fitted to the head of the screw member in phase, the clamp member operates. It is known that the rotation of the screw member is restricted by pinching the shaft portion of the screw member to prevent the screw member from rotating together before the socket is fitted into the head.

The socket contacts the head of the screw member, pushing the screw member in the axial direction, and this pressing force causes both clamp pieces to swing toward the closing side via the lever portion, thereby gripping the shaft portion of the screw member. In this case, the rotation of the screw member is restricted, the socket rotates relative to the head of the screw member, and the socket is fitted into the head when the phase is aligned with the head.

A semi-cylindrical chuck portion 5a is formed at the upper end of each clamp piece 5, as shown in FIG. By swinging the pieces 5, 5 toward the closing side, the shaft portion _a1 of the bolt a can be gripped between the chuck portions 5a, 5a. Further, lever portions 5b, 5b are protrudingly provided at the lower ends of one clamp piece 5 and the other clamp piece 5 to receive the shaft end of the bolt a by shifting their positions to one side and the other side, and Lever parts 5b, 5

る。 After setting the workpiece in the setting jig, the bolt a is inserted into the machine frame 1 through the bolt insertion hole 3a of the upper plate 3. In this case, the shaft part _a1 of the bolt a is the tick part 5a of the pair of clamp pieces 5, 5 in the open position,
It is inserted between levers 5b and 5a, and its shaft end is inserted between levers 5b and 5a.
Bolt a is stopped when seated on the upper surface of bolt b.

ソケツト９が頭部a₂に嵌合する。 Next, when receiving the workpiece W into the assembly device, the socket 9 of the nut runner is lowered while rotating at a slow speed, and the socket 9 is fitted into the head _a2 of the bolt a. In this case, the bolt a is first pushed by the socket 9. When lowered, both clamp pieces 5, 5 are attached to the lever part 5.
The pressing force acting on the bolts b and 5b causes them to swing toward the closing side against the spring 7, and the shaft portion _a1 of the bolt a is sandwiched between the chuck portions 5a and 5a, thereby restricting the rotation of the bolt a, and the socket 9 is rotated relative to the head _a2 of the bolt a, and when the phase is aligned with the head _a2 , the socket 9 is fitted into the head _a2 .

解かれる。 Then, with the head _a2 held in the socket 9 by attraction by a built-in magnet (not shown), the socket 9 is raised to pull up the bolt a. At this time, both the clamp pieces 5, 5 are connected to the lever portions 5b, 5.
Since no downward force is applied to b, it swings toward the opening side due to the biasing force of spring 7, and bolt a is released from its grip.
