Specifically, the web bonding area comprises a windward web bonding area and a leeward web bonding area, and the webs are bonded at the windward web bonding area and the leeward web bonding area by adopting the method, so that the operation time is saved, and the operation efficiency is improved.
The preset position is the position of the outer side edge of the blade main beam or the position of the outer side edge of the blade mould. In some examples, when the first connecting member 112 and the second connecting member 122 are of an integral structure, the outer edge of one of the first positioning member 111 and the second positioning member 121, that is, the second side b of one of the first positioning member 111 and the second positioning member 121, is aligned with the position of the outer edge of the main beam of the blade or the outer edge of the blade mold for bonding and positioning, and the other one is automatically positioned due to the limitation of the lengths of the first connecting member 112 and the second connecting member 122, so that secondary measurement and positioning are not needed, and the whole process is measured by only referring to one coordinate system, so that the problems of repeated labor and accumulated amplification of positioning errors caused by bonding in times can be solved. In other examples, when the first connecting member 112 and the second connecting member 122 are of a split structure, the outer edge of one of the first positioning member 111 or the second positioning member 121 is set according to a predetermined distance by taking the position of the outer edge of the blade main beam or the outer edge of the blade mold as a reference, so as to perform bonding positioning, and the other one accurately determines the distance between the first positioning member 111 and the second positioning member 121 according to the distance between the webs and through a corresponding scale table on the first connecting member 112 or the second connecting member 122, wherein the process reference coordinate system is consistent with the coordinate system of the first positioning member 111 or the second positioning member 121 bonded first, so that the problems of repeated labor and accumulated amplification of positioning errors caused by fractional bonding can be solved.
S130: the first connecting member 112 and the second connecting member 122 are laid on the bonding area of the web, so that the first positioning member 111 and the second positioning member 121 are spaced apart by a predetermined distance.
In particular, the predetermined distance is the spacing of the outboard edge of one web flange from the outboard edge of another web flange adjacent thereto or the width of a single web flange. The embodiment of the invention is suitable for a multi-web structure blade or a single-web structure blade, correspondingly, when a plurality of webs are connected, the preset distance is the distance between the outer side edge of one web flange and the outer side edge of another web flange which is adjacent to the outer side edge of the web flange, and the preset distance can also be the width of one web flange, the distance between two web flanges and the width of the other web flange; when joining a single web, the predetermined distance is the width of the single web flange.
Further, after the first connecting member 112 and the second connecting member 122 are laid on the web bonding area, the outer edge of the web flange is aligned with the inner edge of the first positioning member 111 or the second positioning member 121, that is, the outer edge of the web flange is aligned with the first side surface a of the first positioning member 111 or the second positioning member 121 having a radian, so as to eliminate the problems of bonding errors and rework caused by recognition errors of an operator.
S140: the web is bonded to the web bonding area such that the web flange is positioned between the first positioning member 111 and the second positioning member 121.
According to the web assembling method provided by the embodiment of the invention, in the process of connecting and forming the web and the blade shell, only one of the first positioning piece 111 and the second positioning piece 121 needs to be measured and positioned once, and the other one can be automatically positioned according to the first connecting piece 112 with the preset length, so that the web assembling precision is improved, the web assembling time is greatly shortened, and the working efficiency is improved.
