Laser-electric arc composite welding head adjusting device

Abstract

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.

Description

technical field [0001] The invention relates to the field of laser-arc compound welding, in particular to a laser-arc compound welding head adjusting device. Background technique [0002] Laser-arc hybrid welding technology was first proposed by British scholar W.steen in the late 1970s. The main idea is to use the arc energy to obtain greater welding penetration under the condition of smaller laser power, and at the same time improve the adaptability of the laser welding seam gap to achieve high-efficiency and high-quality welding. In production, the angle and coordinates of the welding torch relative to the laser beam can be adjusted conveniently, which can ensure that the laser welding head and welding torch are in a suitable relative position, and ensure the quality of composite welding and good forming effect.

Problems solved by technology

[0003] Patent CN102380730A discloses a laser composite welding head adjustment mechanism, which is characterized in that a spiral sleeve is installed in the hole of the aluminum alloy plate, the laser head is installed on the spiral sleeve, the sleeve seat is fixed on the aluminum alloy plate by screws, and the guide post The rack and rack are installed in the sleeve of the sleeve seat, the gear is embedded on the knob, the jacket is connected with the guide post through the first wing nut, the welding torch is installed on the jacket, and fixed by the second wing nut. The advantages are: Adjustable light - wire spacing and welding torch angle, the disadvantage is that the three-dimensional coordinates of the welding torch relative to the laser beam cannot be adjusted

Its advantage is to realize the synchronous movement of the welding torch and the laser welding head, so that the relative position of the arc and the laser is stable, convenient, adjustable and accurately positioned during the composite welding process; its disadvantage is that the angle of the laser welding torch relative to the arc welding torch is fixed and cannot be adjusted. The adjustment mechanism is large

Its shortcoming is that it can only realize two-dimensional position adjustment, and the angle of the laser welding torch relative to the arc welding torch is also fixed and cannot be adjusted.
