Problems solved by technology

[0004] The existing welding methods for the engine room platform mostly use manual welding. During welding, the various parts are spliced ​​according to the requirements, and then the workers hold the parts with their hands while performing manual welding. However, this welding method is extremely unstable. It is easy to move and dislocate during welding, resulting in low welding accuracy

The key point of the technical solution is a welding method for a fan nacelle platform, which includes the following steps: S1, placing the bottom plate; S2, installing the first pillar and the second Strut; S3, install the locking block; S4, place the bottom frame, connecting plate, fixing plate and abutting plate as required; S5, position the connecting plate, fixing plate and abutting plate; S6, install the side plate and Plate positioning; S7, positioning the abutting plate and connecting plate close to the notch; S8, positioning the rear plate, connecting plate and connecting plate, so as to improve the welding accuracy.

Description

technical field [0001] The invention relates to the technical field of welding methods, in particular to a welding method for a fan nacelle platform. Background technique [0002] As the energy crisis continues to intensify, clean wind energy is currently a relatively popular energy source. Wind energy is often used in wind power generators, and wind power generators include engine room platforms. [0003] Such as figure 1 As shown, the engine room platform includes a bottom plate 1, and a circular upper ladder hole 11 is opened on the bottom plate 1. The upper ladder hole 11 is used to send the straight ladder into the cabin. The bottom plate 1 is a special-shaped plate, and one side of the bottom plate 1 is irregular. Arc-shaped, the base plate 1 is cut and provided with a notch 14 on the side adjacent to the arc segment, the notch 14 runs through the base plate 1 in a direction away from the arc segment, and the base plate 1 is provided with a connecting groove 1231 on t...
