[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 As shown, the utility model is a positioning tool for blade welding, comprising a first workbench 10, a rotating table 11 arranged on the first workbench 10, a plurality of support plates 12 arranged on the circumference of the rotating table 11 and distributed at equal intervals and with the same inclination angle, and a plurality of cover plates 13. The first workbench 10 is fixed on a first bracket 30.

[0027] Combination Figure 3 and Figure 6 As shown, the rotating platform 11 has a housing cavity 14 for accommodating the motor housing 9. The upper end of the housing cavity 14 is open 141. A plurality of notches 142 are evenly distributed on the upper edge of the rotating platform to match the bending angle of the blades 8. The number of the notches 142 is equal to the number of the support plates 12.

[0028] There are five support plates 12. The support plates 12 are arc-shaped plates, and the curvature of the support plates 12 matches the curvature of the blades 8. A cylindrical plug 121 extending outward is provided at the root 123 of the support plate 12, and a plurality of sockets 122 are provided on the upper circumference of the rotating table 11. The plug 121 of each support plate 12 is inserted into the corresponding socket 122. During assembly, the plugs 121 of all support plates 12 are inserted into the corresponding sockets 122, and all support plates 12 are fixed to the outer surface of the rotating table 11 by welding. The inclination angle of the support plate 12 on the rotating table 11 makes the air volume and air pressure effect of the blades 8 welded to the motor housing best.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown, in addition, the bottom surface of the rotating table 11 has a rotating shaft 111 extending downward. An axial hole 101 is opened in the center of the first workbench 10. The rotating shaft 111 of the rotating table 11 is inserted into the axial hole 101. In this way, during the welding operation, the operator can rotate the rotating table 11 according to actual needs to adjust the position to be welded.

[0030] like Figure 1 and Figure 4 As shown, the cover plate 13 is a U-shaped plate, which is composed of a top plate 131 and side plates 132 located on both sides of the top plate 131. The opening width of the cover plate 13 is adapted to the width of the support plate 12, and the length of the cover plate 13 is less than the length of the support plate 12. With this structure, the cover plate 13 is covered on the support plate 12, and the blades to be welded can be pressed to prevent the blades 8 from being displaced during the welding process. In addition, the length of the cover plate 13 is less than the length of the support plate 12, so that when the cover plate 13 is covered on the free end of the support plate 12, there is a gap between the end of the cover plate 13 and the outer side surface of the rotating table 11, thereby avoiding interference with the welding of the welding surface between the blade 8 and the motor housing 9.

[0031] The top plate 131 is an arc-shaped plate, and the curvature of the top plate 131 is adapted to the curvature of the blade 8. In this way, the cover plate 13 can better press the blade 8.

[0032] A handle 133 is mounted on the top surface of the cover plate 13 .

[0033] Combination Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the second workbench 20 is also included. The second workbench 20 has a hollow cylindrical inner fixing portion 21 and an outer fixing portion 22. The inner fixing portion 21 is arranged inside the outer fixing portion 22. The second workbench 20 is fixed to the second bracket 31. When in use, the inner fixing portion 21 is sleeved on the outer edge of the rotating shaft 7 on the motor housing 9. The outer fixing portion 22 is sleeved on the outer edge of the upper part of the motor housing 9. There is a gap between the root 801 of the blade 8 and the upper edge of the outer fixing portion 22.

[0034] The above is the positioning tooling for blade welding, and its working method is as follows:

[0035] First, place the top of the motor housing 9 in the accommodating cavity 14. The blades 8 are placed on the corresponding support plates 12, and the root 801 of each blade 8 passes through the corresponding notch 142. The cylindrical protrusion 802 of the root 801 of the blade 8 is inserted into the corresponding circular hole 803 on the motor housing 9. The rear end face of the blade 8 is fitted with the outer side of the motor housing 9 to form two positive and negative welding surfaces. Subsequently, all the cover plates 13 are respectively covered on the corresponding support plates 12 to press the blades 8, and then the positive welding surfaces are welded one by one. After that, the motor housing 9 is taken out, and the rotating shaft 7 of the motor housing 9 is inserted into the inner fixing part 21 of the second workbench 20, and the bottom of the motor housing is inserted into the outer fixing part 22. Subsequently, the negative welding surfaces are welded one by one to complete the welding operation.

[0036] In summary, the utility model can quickly position the blades and prevent blade displacement by closing the cover plate on the support plate; during the welding process, the operator can rotate the rotating table to adjust the welding position according to actual needs, thereby reducing labor intensity, improving work efficiency and welding quality, and thus realizing unified production standardization.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
