Abstract

PURPOSE: To control and set easily as you desire by using the non-contact displacement meter for detection of the change of position of edge.
CONSTITUTION: The detection bar 8 equipped with contact probe becomes to be possible to float at the spherical bearing 18 and a part of the bar is inserted in the barrel body 20 equipped with installation arm 21. And, it is pressed in the direction of the shaft by the spring 9. Metallic cylinder type detection body 17 is fixed on the bar 8 and inside this body, the non-contact displacement meters 13, 14 crossed at right angles with each other, are installed at the right angle to the core of the bar 8. This detector 25, moving stands 27, 28 and welding torch 26 are installed on the arm 29 installed on the carriage. At first, the contact probe 3 is inseted in the edge of the weld zone and the control circuit 23 is adjusted. In case the gap of the position is occurred in accordance with the movement of arm 29 due to the transformation of the weld material 2, signal is transmitted from the circuit 23 by the change of the gap between the displacement meters 13, 14 and the detector 17 through the contact probe 3. To set the deviation of the setting value and this to zero, driving correction in horizontal direction 27 of the moving stand is made through the driving circuit 24, and detection and correction are corrected repeatedly. Hight direction can simultaneously be detected.
