Because the layout positions of the two motor hanging seat plates 203 on the beam pipe 201 are close, and the layout postures have relative position relation requirements and precision requirements at the same time, even if the two are positioned by adopting the conventional universal fixture with high-density compact layout, the fixtures still conflict and interfere with each other, reasonable arrangement cannot be realized, the excessive conventional positioning fixtures also occupy and obstruct the operating space of the welding manipulator, the welding process of the welding manipulator needs to be stopped and adjusted for many times midway, and all operations cannot be finished continuously.
On the other hand, even if the positioning and welding of the two on the cross beam pipe 201 are temporarily realized according to the correct positioning posture, if the positioning is realized only by the self structure of the welding position and the relative position between the two and the cross beam pipe 201 cannot be continuously maintained, the positioning postures of the two will be significantly changed again under the influence of the subsequent welding thermal shrinkage deformation, so that not only the positioning accuracy cannot be effectively guaranteed, but also the cross beam pipe 201 is subjected to a large drawing effect, so that the cross beam pipe 201 is subjected to distortion deformation, the mechanical structure strength is reduced, and the heavy subsequent remedial work is required to correct the distortion, so that extra manpower and material resources are wasted, the production takt is prolonged, the production efficiency is reduced, the manufacturing cost is increased, and the economic benefit is reduced.
