た。(Problem to be solved by the invention) In the conventional device as described above, even if the bolt is automatically supplied to the socket part of the nut runner, the Y-shaped chuck is fixed in only one fixed position. Therefore, when the nut runner is operated to bring the bolt close to the workpiece and tighten it, the Y-shaped chuck does not follow the downward movement of the nut runner. In other words, the socket of the nut runner is
The bolts supplied to the Y-shaped chuck are caught and moved down toward the workpiece, which is an independent operation, and there is a problem with stability, such as falling bolts and diagonal tightening. .

きは、作用せずたるんでいる。 Reference numeral 11 denotes hanging rods erected on both sides of one end of the support plate 9, which correspond to guide cases 13 provided on both sides of the lower end base 12 of the nut runner unit 1.
A stopper 14 is provided at the upper end. Therefore, as shown in FIG. 1, when the apparatus is being lifted, the Y-type chuck unit 8 is maintained at a constant distance from the nut runner unit 1 with the hanging rod 11 being lowered. Reference numeral 15 denotes a Y-shaped chuck unit lifting cylinder provided on both sides of one end of the mounting plate 6, and a wire (or chain) is connected between the rod end and the upper end of the suspension rod 11.
It is connected by 16. By the way, the above wire 16
The length of the Y-shaped chuck unit 8 is determined to determine the proximity position of the Y-type chuck unit 8 to the workpiece, and when the device is in the raised position as shown in FIG. 1, it does not function and is slack.

操作にそなえ待機する。 The present invention has a structure as described in the embodiments above, and when tightening bolts, first the lifting cylinder 7 is operated to simultaneously lower the nut runner unit 1 and the Y-type chuck unit 8 while maintaining a predetermined relative distance. During the descent, the wire 16 is fully extended, and at this point the Y-shaped chuck unit 8 stops falling, and its lower end is held at an optimal position close to the bolt hole of the workpiece A, as shown in FIG. When the nut runner 1 is further lowered, the socket 1a catches and pushes the bolt in the Y-type chuck unit 8, aligning the bolt with the bolt hole of the workpiece A and making it possible to tighten it, and then begins the tightening operation. However, just before the completion of tightening, cylinder 1

Since it has a function of simultaneously lowering the bolt by a certain amount together with the runner unit and first stabilizing the bolt in close proximity to the workpiece, then the tightening operation is started, so that reliable bolt tightening can be achieved. In addition, since the Y-shaped chuck unit is pulled up just before the completion of tightening, there is no problem with the work at the completion of tightening. If an abnormality occurs in the bolt supply device, it is possible to stop the supply of bolts and perform the tightening operation as a normal nut runner (temporarily tightening the bolts to the workpiece).
