Multi-directional adjustment welding device for laser-MIG/MAG (metal-inert gas/metal active gas) welding equipment

Abstract

Disclosed is a multi-directional adjustment welding device for laser-MIG / MAG welding equipment. A laser lighting gun and a welding gun of the laser-MIG / MAG welding equipment can be assembled on the multi-directional adjustment welding device, a first driving motor drives a first lead screw to enable a first support to move along two linear flat guide rails in a vertical reciprocating mode in a Z direction, a second driving motor synchronously drives a second lead screw to enable a right-angled seat to move along a positioning cylinder in a horizontal reciprocating mode in an X direction, a third driving motor drives a third lead screw to enable a third support to move along two round guide rails in a horizontal reciprocating mode in a Y direction, and a fourth driving motor drives a clamping seat to move along long-sector guide rails towards the arc surface of a sector in a reciprocating mode. The Z direction, the X direction and the Y direction form a three-dimensional coordinate system and form the four-directional, namely, multi-directional adjustment when combined with the A direction. The welding gun is fixed onto a welding gun clamp and the laser lighting gun is fixed onto the first support. The multi-directional adjustment welding device for the laser-MIG / MAG welding equipment has the advantage of achieving the four-directional position adjustment of the laser lighting gun and the welding gun and being novel and unique in structure.

Description

technical field [0001] The invention belongs to the technical field of laser welding auxiliary devices, in particular to a multidirectional adjustment welding device for laser-MIG / MAG welding equipment. Background technique [0002] Laser-MIG / MAG composite welding equipment is mostly used for various welding in shipbuilding, and usually includes a laser irradiation gun head and a welding torch. Usually, the laser irradiation gun head is vertically aligned with the welding workpiece, and the distance between the welding torch and the laser irradiation gun head not only requires a certain distance Control, and the welding torch should also have a certain angle control relative to the laser irradiation torch head. [0003] The laser-MIG / MAG hybrid welding device developed by Austrian Fronius company mainly has the following shortcomings: [0004] 1. The angle control of the welding torch relative to the laser irradiation torch head is relatively fixed, which is not suitable fo...

AI Technical Summary

Problems solved by technology

[0004] 1. The angle control of the welding torch relative to the laser irradiation torch head is relatively fixed, which is not suitable for welding T-joints in shipbuilding;

[0005] 2. The welding seam tracking system is used to control the distance between the welding gun and the laser irradiation gun head, which leads to the deviation between the robot's TCP point and the welding seam tracking point, and the welding seam tracking system needs to be recalibrated continuously;

[0007] The laser-arc hybrid welding device developed by ESAB is mainly used for the welding of large machine tools. The structure of the hybrid welding device is complex and the size is large, and the distance control and angle control between the welding torch and the laser irradiation gun head are manually adjusted.

[0008] Due to their respective shortcomings, the above two composite welding devices are difficult to meet various welding needs such as shipbuilding
