However, for the thin-wall long cylinder body welding external small parts, the dislocation of the welded external small parts and the deformation of the cylinder body are difficult to reach relevant manufacturability indexes. The main reasons for this manufacturability problem are: 1) When the matching relation between the positioning element for the thin-wall long cylinder and the cylinder in the process device is clearance matching, a system positioning error is generated; 2) Because the weight of the process device is limited, the rigidity of the positioning element of the external small part is insufficient, so that the external small part cannot be positioned accurately; 3) When the external small part compressing mechanism is designed into a manual compressing mode, the compressing force of all external small parts received by the cylinder is different in sequence, and the compressing force is uncontrollable, so that the cylinder is stressed unevenly in the circumferential direction, the cylinder deflects, and the external parts are misplaced; 4) Welding external small parts on the thin-wall cylinder belongs to local welding, and the welding part of the cylinder is heated to deform. In addition, due to the structural limitation of the thin-wall cylinder, the designed welding process device is large in weight, and when manual clamping and welding are carried out, the labor intensity of workers is high, so that the welding processing efficiency is reduced.
