[0025] As Figures 1 to 7 Shown in the figure, a wing-shaped blade combined welding positioning tooling according to an embodiment of the present invention includes a positioning main body 10, which is fixedly connected and formed by a first positioning plate 101, a second positioning plate 103 and a plurality of connecting pieces 102. A first notch 1011 is provided in the upper part of the first positioning plate 101, and a second notch 1031 is provided in the upper part of the second positioning plate 103. The positioning main body 10 restricts the movement of the leeward panel 2, the windward panel 1 and the round steel 4 to be welded in the inner and outer directions through the first notch 1011 and the second notch 1031. The reinforcing rib 3 is arranged between the leeward panel 2 and the windward panel 1; the side baffle 20 is arranged on one side of the first positioning plate 101 to make one side of the leeward panel 2 and the windward panel 1 to be welded abut flush; a limiting piece 30 for restricting the position of the round steel 4 is arranged on the side baffle 20 and / or the first positioning plate 101; the side positioning plate 40 is arranged on the side of the second positioning plate 103 away from the first positioning plate 101 through the adjusting piece 50. A third notch 401 is provided in the upper part of the side positioning plate 40. The distance between the side positioning plate 40 and the second positioning plate 103 is adjustable, so that the third notch 401 positions the side part of the leeward panel 2; there are three connecting pieces 102 and they are arranged in parallel; the limiting piece 30 includes a welding nut 301 fixed on the first positioning plate 101 and a limiting rod 302 screwed with the welding nut 301; the limiting piece 30 further includes a locking nut 303 screwed on the limiting rod 302; there are two side positioning plates 40, and the adjusting piece 50 includes an adjusting screw rod 501 and a plurality of adjusting nuts 502 screwed on the adjusting screw rod 501.

[0026] The scheme can completely restore the outer contour curve of the blade design, can adjust the fitting curved surface of different cross-sections as needed, and the position of the cross-section can also be continuously adjusted manually and steplessly; highly integrated, it can simultaneously meet the positioning of four or five parts together, omitting the scribing positioning operation, greatly improving the production efficiency; reducing the difficulty of the positioning scribing work during manual welding. This positioning tooling is designed, which can not only meet the positioning of each component, improve the accuracy, but also reduce the difficulty of the scribing operation, improve the production efficiency and reduce the defective products.

[0027] During specific use, for the convenience of understanding the present invention, it is described in conjunction with the attached drawings;

[0028] See Figures 5 to 7 Before welding, the positioning body 10 formed by the first positioning plate 101, the second positioning plate 103, and the connecting member 102 plays a supporting role. The side baffle 20 keeps the windward panel 1 and the leeward panel 2 in abutting alignment on one side. The limiting member 30 restricts the position of one end of the round steel 4. The two side positioning plates 40 can restrict the position of the other side of the leeward panel 2 away from the side baffle 20. The reinforcing ribs are arranged between the leeward panel and the windward panel. In this way, the accurate positioning of the windward panel, the leeward panel, the two reinforcing ribs, and a round steel is achieved. After that, first, by means of manual spot welding, a plurality of parts are fixedly connected to form an integral wing-shaped blade. Then, the wing-shaped blade is removed from the positioning tooling for full welding.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
