基于CLOOS焊接机器人对液压支架结构件坡口焊接工艺研究

Research on Groove Welding Process of Hydraulic Support Structural Parts Based on CLOOS Welding Robot

机器人采用坡口立放横焊焊接支架顶梁、底座、掩护梁等结构件时,枪姿态、焊接参数等不宜控制、熔深不够,导致焊接时施工难度大。针对CLOOS焊接机器人对液压支架结构件顶梁、底座、掩护梁、连杆、主肋与贴板圆弧处坡口立放横焊接进行参数优化。重点对盖板、主肋和贴板圆弧处18 mm×40°、18 mm×45°单边V形坡口立放横焊机器人焊接参数进行分析研究。在保证焊接接头性能的前提下,显著提升机器人焊接工作效率,提高结构件的外观质量,节约生产成本,减轻工人劳动强度。

When the robot adopts groove vertical horizontal welding bracket top beam,base,cover beam and other structural parts,the gun attitude,welding parameters,etc.are not suitable for control,and the penetration depth is not enough,resulting in difficult construction during welding.Optimized the parameters of CLOOS welding robot on the top beam,base,cover beam,connecting rod and other main reinforcement and veneer arc of hydraulic support structural parts,and groove vertical and horizontal welding.The welding parameters of the 18 mm×40°and 18 mm×45°single-sided V groove vertical horizontal welding robot at the arc of the cover plate,main bar and veneer were analyzed and studied.Under the premise of ensuring the performance of welding joints,it significantly improves the efficiency of robot welding,improves the appearance quality of structural parts,saves production costs,and reduces the labor intensity of workers.
