Background In the production process of the corrugated pipe compensator, the welding of the guide cylinder is important, because the core function of the guide cylinder is to provide a smooth flow passage for a medium and protect the corrugated pipe, the aims of scour prevention, flow guide resistance reduction and vibration prevention are achieved, the guide cylinder is sleeved in the corrugated pipe, one end of the guide cylinder is welded with the end part of the corrugated pipe, the welding operation is concentrated on the end part of the corrugated pipe, the corrugated pipe is a movable hose, the integral form of the corrugated pipe is correspondingly changed when the end part is stressed, and the welding of the guide cylinder and the corrugated pipe is required to ensure the stability of the corrugated pipe. In order to meet the stability of the corrugated pipe, if a mode of clamping at two ends is adopted, a welding mechanism at the end part can generate moving interference with a clamping mechanism at the end part, the welding port is circular and is positioned in the corrugated pipe, the corrugated pipe needs to integrally rotate so as to avoid the rotation of the welding mechanism, thereby avoiding the stranded wire of the welding mechanism, if one end is adopted for clamping, and the corrugated pipe is compressed along the axis, the corrugated pipe can be changed into a rigid straight pipe from a hose, still the purpose of fixing the corrugated pipe can be achieved, at the moment, the welding mechanism is arranged on a pressing plate, the end part of the corrugated pipe can rotate along with the rotation of a bearing on the pressing plate, the problems of moving interference and stranded wire can be avoided, but the maximum compression displacement amount of the corrugated pipes with different inner diameters is different, and the axial rigidity of the corrugated pipes is in cube proportion, namelyThis means that the inner diameter is doubled, the rigidity is approximately 8 times that of the original corrugated pipe, the expansion and contraction amount can be reduced to 1/8 of that of the original corrugated pipe under the action of the same force, and if the corrugated pipe is excessively compressed, the corrugated pipe is extremely easy to break, so that the inner diameter of the corrugated pipe needs to be considered while the corrugated pipe is compressed and fixed. Through retrieval, chinese patent application CN118357659A discloses an automatic welding device and a welding method of a metal corrugated pipe compensator, and the automatic welding device is simple to operate and realizes full-automatic production, but the welding of a guide cylinder and a corrugated pipe cannot avoid the problems, and the maximum compression displacement of the corrugated pipe cannot be automatically determined, so that the corrugated pipe is extremely easy to be compressed excessively to damage or is too small to be fully fixed, the welding efficiency is reduced, the welding quality is influenced, the fixing of the corrugated pipe and the determination of the maximum compression displacement cannot be completed simultaneously, and the step operation is time-consuming and labor-consuming.
