Embodiment Construction

[0030] Hereinafter, the invention will be further described in conjunction with the drawings and specific embodiments.

[0031] How it works: by figure 1 with 2 As shown in the schematic diagram of the device, the whole protection device is fixed on the laser head by two mounting studs, forming a side blowing protective airflow field during welding. Each stud is provided with two nuts respectively, and two nuts are used to fix the height. The adjustment plate and the horizontal distance between the nozzle outlet and the laser optical axis; a chute is arranged in the middle of the height adjustment plate, and the chute is used to fix the adjustment plate and adjust the height of the shielding gas nozzle.

[0032] Specifically, the laser flexible welding weld gas protection device includes: a mounting stud 1, a height adjustment plate 2, a fixing nut 3, a shielding gas nozzle 4, and a nozzle fixing member 6;

[0033] The height adjustment plate 2 is provided with a chute in the middle;...

Abstract

The invention provides a gas protection device for a welded joint formed by laser flexible welding. Two fixing bolts are mounted on a welding head; a protection gas nozzle is connected to a height adjustment plate; a sliding chute is formed in the height adjustment plate, so that the height adjustment plate can be used for adjusting the height of the protection gas nozzle and a transverse distance between the protection gas nozzle and the welding head; a fixed angle is formed at the lower end of the height adjustment plate; the gas nozzle is always in an optimal protection gas lateral blowing angle; the section of a protection gas spraying opening is an elliptical section. By the chute in the height adjustment plate, nuts on the fixing bolts and the fixed angle at the lower end of the height adjustment plate, the upper and lower distance and the left and right distance of the protection gas nozzle can be adjusted, and the angle of the protection gas nozzle can be fixed; therefore, the welded joint can be always well protected by protection gas, a welding defect, caused by poor protection, of the welded joint is avoided, and the welding quality is guaranteed.

Description

Technical field [0001] The invention relates to a gas protection device during laser welding, in particular to a gas protection device for welding seams during laser flexible welding. It belongs to the field of laser welding technology. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy density laser beam as a source for welding. Because of its advantages such as high energy density, deep penetration, high precision, and strong adaptability, it has been valued by developed countries. Laser welding plays a very important role in the welding of some special materials and structures. This welding method is more and more widely used in high-tech fields such as aerospace, electronics, automobile manufacturing, and nuclear power. [0003] Welding robots are advanced welding equipment developed on the basis of industrial robots and are robot production units specialized in welding. Since the welding robot has many advantages s...
