Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seam welding tooling, in particular to a seam welding tooling for an engine tail nozzle. Background Art
[0002] The seam welding tool is a device used to limit and stabilize parts during the processing. For example, in the production and processing of the tail nozzle, due to the large size of the product, thin-walled hollow, poor overall rigidity and strength, welding and cutting processes are prone to cause processing deformation and other problems. The traditional seam welding method is carried out by two workers, one holding the part and the other operating the seam welding machine. Not only is the processing efficiency low, but the workers have to adjust the working angle and rotation speed of the parts during welding, which can easily cause unstable weld quality and high labor intensity, which seriously restricts the production progress of the parts. Therefore, seam welding tooling is used to limit the parts to improve the welding effect.
[0003] When using traditional seam welding tooling, the two parts of the tail nozzle parts are fitted together, and the inner walls of the two parts are installed and fixed on the main fixed head of the cantilever, and then the two ends of the auxiliary fixing frame on the cantilever are respectively fixedly connected to the air outlets of the two parts, and then the gap of the parts is welded. At this time, the support rod on the base of the seam welding tooling will support the stable rotation of the cantilever, and the rotation will drive the cantilever to rotate, so as to weld the various parts of the parts, and the screw adjustment frame of the seam welding tooling will adjust the height of the parts. At this time, the processing and welding of the tail nozzle parts will be more efficient, and the quality will be further improved. However, it is found in actual use that when the tail nozzle parts are just started to be welded and the weld has not yet been formed, the mutual connectivity of the two parts is poor, and stable mutual contact and extrusion is not formed, which leads to a larger weld during welding, reduces the forming effect of the parts, and reduces the practicality of the seam welding tooling.
