面で不利であつた。(b) Conventional technology Conventionally, as a device for tightening a nut onto a shaft to be screwed, a probe (probe) protruding from the center of a tightening wrench head is used to pull up the nut from a pedestal, and the probe is then used to tighten the nut onto a shaft to be screwed. It has been proposed that the nut is applied to the end face of the shaft, and then the spanner head is rotated and advanced to screw the nut onto the shaft to be screwed. This is the one described in Japanese Patent Publication No. 50-21021. In this device, after hooking the nut with the probe, the pedestal is shifted upward so that the spanner head can reach the shaft to be screwed without being obstructed by the pedestal. However, a complicated mechanism consisting of an eccentric cam and a crank is used at the top and bottom of the pedestal, which is disadvantageous in terms of cost and adjustment effort.

る。(f) Example In the figure, 1 is the base of the device of the present invention.
Reference numeral 2 denotes a horizontally supported shaft to be screwed, into which a component 3 is fitted into a male threaded portion 2a at the tip and is ready for screwing with a nut. Reference numeral 4 denotes a reciprocating table which is linearly slidably supported on the base 1 so as to move forward and backward in the axial direction of the screwed shaft 2, and has a bearing mount 5 on the upper surface. The bearing mount 5 rotatably supports the shaft portion of the spanner head 8 by a pair of radial bearings 6 and a pair of thrust bearings 7. Spanner head 8
is the motor 9 (fourth motor) also supported on the carriage 4.
(shown in the figure) via a joint 10, and a tightening torque can be applied to it. The shaft portion of the spanner head 8 is hollow, and a probe 11 having a retaining flange at its base and a compression coil spring 12 are inserted therein.
The probe 11 is forced to protrude forward from the center of the spanner head 8 by the biasing force of a spring 12.
The spanner head 8 is supported in parallel with the shaft 2 to be screwed and so as to face the end face of the shaft.

る。 Reference numeral 13 denotes a nut holder placed between the screwed shaft 2 and the carriage 4. The pedestal 13 is vertically movably supported by a pair of guide pins 14 installed upright on the base 1, and is pushed upward by a compression coil spring 15 (shown in FIGS. 5 and 6) inserted between the pedestal 13 and the base 1. It's been raised. The head of the guide pin 14 is the pedestal 1
It acts as a stopper to restrict the rise of 3. A recessed fitting part 17 is formed on the upper surface of the pedestal 13 to hold the nut 16 at a height such that its center hole faces the probe 11. The front and back of the recessed fitting portion 17 are cut-outs 18 through which the probe 11 passes. Numeral 19 is a nut feeder placed above the pedestal 13, and as shown in FIGS. 5 and 6, the vertical chute 20
The nuts 16 that are sent in an aligned state are separated one by one by a slider 21 and dropped into the recessed fitting part 17 of the pedestal 13. Therefore, as the carriage 4 moves forward, the carriage 4 and the pedestal 13 are attached to each other.
A cam device 22 for lowering the cam 3 is provided. In the embodiment, a wedge-shaped plate cam 23 fixed to the carriage 4 and a roller-like cam follower 24 pivotally supported on the side surface of the pedestal 13 constitute the cam device 22 .

付作業に備えるものである。 Next, the action will be explained. When the carriage 4 starts moving forward toward the screwed shaft 2 from the state shown in FIG. 1, the probe 11 is first inserted into the center hole of the nut 16. This is the situation shown in FIG. The cam 23 then begins to come into contact with the cam follower 24, which push down the pedestal 13 against the spring 15 and open the path for the spanner head 8. The probe 11 moves forward while hooking the nut 16, and stops there when it hits the screwed shaft 2. Since the spanner head 8 is still moving forward, the probe 11 is drawn into the spanner head 8 against the force of the spring 12. This is the state shown in FIG. The spanner head 8, which moves forward while being rotated by the electric motor 9, finally catches the nut 16 and screws it onto the shaft 2, as shown in FIG. When the tightening torque of the nut 16 reaches a predetermined value, the electric motor 9 stops, and the carriage 4
is moved backward to prepare for the nut tightening work for the new shaft 2 to be screwed.

Therefore, the cost is low, the design and assembly adjustment are easy, and the reliability is improved.
