[0021] As FIG. 1 and FIG. 2As shown, the range hood box body welding tool in the embodiment is used to act on the side plate 102 of the range hood box body 100, and by extruding and deforming the side plate 102 of the range hood box body 100, the gap between the side plate 102 and the front plate 103 of the range hood box body 100 is reduced, which facilitates welding of the two, and good welding effect can be ensured without additional wire welding.
[0022] Specifically, the range hood box body 100 generally includes a rear plate 101, side plates 102 fixed on the left and right sides of the rear plate 101, and a front plate 103 arranged in front of the rear plate 101 and between the two side plates 102, and the left and right sides of the front plate 103 respectively have welding portions corresponding to the two side plates 102. In the case that the gap between the welding portions of the front plate 103 and the two side plates 102 is small, good welding can be achieved without additional wire.
[0023] As shown in FIG. 1 and FIG. 2 FIG. 1 FIG. 2 As shown, the range hood box body welding tool in the embodiment includes a bottom plate 1, a first positioning member 2, and a driving mechanism 3. In use, the range hood box body 100 is placed on the bottom plate 1, and the rear plate 101 of the range hood box body 100 is placed on the upper surface of the bottom plate 1.
