AUTOMATIC WELDING MACHINE

摘要

This automatic welding machine (W) is provided with a link operating device (1) in which a distal end side link hub (3) is coupled by way of three or more sets of link mechanisms (4) to a base end side link hub (2), and which is capable of freely changing the attitude of the distal end side link hub (3) relative to the base end side link hub (2). The automatic welding machine (W) is provided with linear actuators (60, 61) in one or more axes, which cause the base end side link hub (2) of the link operating device (1) to move forward or backward relative to a stand (50), and a welding torch (52) is attached to the distal end side link hub (3). The automatic welding machine (W) is also provided with a movement mechanism (53) on which peripheral devices (54, 55) connected to the welding torch (52) by means of cables (56, 57) are mounted in such a way as to be capable of moving in at least one axial direction.
