Laser-electric arc composite welding head adjusting device

The invention relates to the field of the laser-electricity arc composite welding, in particular to a laser-electricity arc composite welding head adjusting device. The laser-electricity arc composite welding head adjusting device comprises a laser welding head, an arc-welding gun, an X-axis adjusting mechanism, a Y-axis adjusting mechanism, a Z-axis adjusting mechanism and a connecting flange. The laser-electricity arc composite welding head adjusting device is characterized in that the connecting flange is connected with the laser welding head. The X-axis adjusting mechanism is connected with an angle-adjusting plate. The angle-adjusting plate is provided with two homocentric arc-shaped slot holes. A screw pin I and a screw pin II are arranged in each arc-shaped slot hole. The screw pin I and the screw pin II are respectively connected with the arc-welding gun. The screw pin I and the screw pin II are distributed along the central axis of the arc-welding gun. When the welding gun can be adjusted to correspond to the angle of a laser beam, the welding gun is rotated in a centre of a welding stick tip end. Compared with prior art, the laser-electricity arc composite welding head adjusting device has the advantages of that angles of the welding gun and locations of the welding gun can be adjusted conveniently, wherein the angles correspond to the laser beam and the locations are along an X direction, a Y direction and a Z direction. Finally, good combination of a laser heat source and an arc-welding heat source can be achieved. The laser-electricity arc composite welding head adjusting device has an important significance on guaranteeing composite welding quality and good shaping effects.
