Description

Technical Field

[0001] The utility model relates to the technical field of exhaust pipe welding, in particular to a mechanical arm welding tool for an exhaust pipe. Background Art

[0002] The quality requirements for the assembly and welding of stainless steel pipes for automobiles are getting higher and higher, the demand is also increasing, and the requirements for process cost control and product consistency are also getting higher and higher. Therefore, the stainless steel pipe assembly welding process is improved and optimized, such as the attached Figure 5 The parts shown in the figure are used to weld two pipe fittings. The traditional manual positioning process is currently used. Due to manual positioning, the product consistency is not uniform and the processing efficiency is low. The conventional automotive stainless steel pipe assembly welding process adopts manual positioning and argon arc welding. The manual assembly is operated by one person. The conventional product assembly time is about 3-5 minutes, and another professional person manually welds. The welding time is about 3-5 minutes for conventional products. However, the disadvantage of this method is that the relative positions of the product parts are not uniform due to personnel changes. The above two people cooperate in assembly and welding, and the positions of the finished product parts are inconsistent, and the welding effect is inconsistent, which directly leads to a decrease in product quality. The skill requirements of personnel are relatively high, which will lead to increased labor costs, low processing efficiency, reduced customer satisfaction, and reduced market competitiveness of products. With the maturity of automation, combined with the above situation, a robot welding tool is designed and developed, from assembly positioning to welding, the positioning tool cooperates with robot welding to improve processing efficiency, improve product quality and reduce labor costs.
