この弁明はエアモータで駆動軸を回転させるナツトラン
ナに関する。DETAILED DESCRIPTION OF THE INVENTION This defense relates to a nut runner whose drive shaft is rotated by an air motor.
従来、この種のナツトランナとしては、駆動軸の締付ト

定時間経過後、エアモータの駆動ヲ゛停止するようにし
たものが知られている。Conventionally, this type of nut runner is equipped with a torque sensor that detects the tightening torque of the drive shaft, and when the tightening torque exceeds a predetermined value, the air motor is stopped or the tightening torque is increased. It is known that the air motor stops driving after a certain period of time has passed after reaching a predetermined value.
しかしながら、上記従来のナツトランナでは、ヌナッグ
トルクを経過して後の締付角度の検出・制御ができない
ため、どうしても熊駄な時間が生じ、作業能率を向上さ
せることができず、またナラ１−の精確な締付作業もで
きないという欠点がめる。However, with the above-mentioned conventional nut runner, it is not possible to detect and control the tightening angle after the nunag torque has passed, so there is an unavoidable waste of time, making it impossible to improve work efficiency, and the accuracy of the nut runner. The disadvantage is that it is not possible to perform proper tightening work.
そこで、この発明の目的は、締付トルクと締付角度の検

るようにしたことを特徴としている。In order to achieve the above object, the nut runner of the present invention is equipped with a torque sensor that detects the tightening torque of a drive shaft driven by an air motor, and a rotation angle sensor that detects the rotation angle of the drive shaft.1. It is characterized by being able to detect and control the tightening torque and tightening angle.

５’に張シ付けている。The internal gear 1 of the planetary gear mechanism 5 is mounted on a frame 12.
The torsion tube 13 is formed at the other end of the torsion tube 13 with one end fixed to the torsion tube 13 by the reaction force of the tightening torque.
I'm trying to twist it. In the torsion tube 13, there is a 1-rain gauge 1' as an example of a torque sensor.
Tension is attached to 5'.

m 18 which fixes the rotary disk 17 and sandwiches the rotating disk 17.
f: The Ia air sensor 19 is fixed to the housing 20 via a mounting plate 22. This rotating disk 17 and the magnetic sensor J9 constitute a rotation angle sensor 21.

なる。According to the nut runner configured as described above, the tightening torque can be detected by the torque sensor 15, and $1 can be outputted by the wide-angle sensor 21 when the drive shaft 7 rotates and reclines. Therefore, after the tightening torque reaches the snug torque according to the output of the torque sensor 15, a trigger signal is output, and the rotation angle sensor 15 outputs a trigger signal.
It becomes possible to detect and control the tightening angle after the snug torque has passed by detecting the rotation angle and the rotation angle.
したがって、無駄な時間をなくして、作業能率を向上で
さ、ナツトの精確な締付作業を行なうことができる。Therefore, wasted time is eliminated, work efficiency is improved, and nuts can be tightened accurately.
