[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impeller structure that is more conducive to welding, including a rear disc, one side of which is sequentially provided with a front disc, a middle disc and blades connected thereto, and a rear disc connecting device is provided at the rear end of the rear disc away from the front disc.

[0006] In a further optimization, the blades are connected to the center disk by plug-in.

[0007] For further optimization, the front and rear ends of the middle disk are respectively fixedly connected to the front disk and the rear disk, and the height of the middle disk is consistent with the height of the blades.

[0008] For further optimization, the front disc and the rear disc are both connected to the blades by spot welding.

[0009] For further optimization, a plurality of inner holes are provided on the rear disc and the front disc.

[0010] For further optimization, the plurality of inner holes are arranged correspondingly in upper and lower parts, and the inner holes are through holes.

[0011] For further optimization, one end of the rear disc connecting device is respectively inserted into the rear disc and the blade.

[0012] Beneficial Effects

[0013] The utility model provides an impeller structure that is more conducive to welding. An automatic welding robot can extend through the inner holes of the rear plate and the front plate to the middle of the blades for welding, thereby reducing the labor production cost and making the impeller more beautiful.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1-2 As shown, an impeller structure more conducive to welding includes a rear disc 4, one side of which is provided with a front disc 1, a middle disc 3 and blades 2 connected thereto in sequence, and a rear disc connecting device 5 is provided at the rear end of the rear disc 4 away from the front disc 1.

[0021] In this embodiment, the blades 2 are plug-connected to the middle disc 3, which facilitates the subsequent connection with the rear disc and the front disc.

[0022] The front and rear ends of the middle plate 3 are fixedly connected to the front plate 1 and the rear plate 4 respectively, and the height of the middle plate 3 is consistent with the height of the blade 2. After the blade 2 is inserted into the middle plate 3, the stability of the blade assembly is achieved and the blade 2 is protected.

[0023] The front disc 1 and the rear disc 4 are both connected to the blade 2 by spot welding. The welding is completed at a high speed through a spot welding process, and has the characteristics of small welding points and good overall connectivity.

[0024] The rear plate 4 and the front plate 1 have the same diameter, and a plurality of inner holes 6 are provided on the rear plate 4 and the front plate 1. The plurality of inner holes 6 are arranged correspondingly up and down, and the inner holes 6 are through holes. The inner holes 6 on the rear plate 4 and the front plate 1 are connected up and down, and the welding robot is inserted into the inner hole 6 to realize precise positioning of spot welding.

[0025] One end of the rear disk connecting device 5 is inserted into the rear disk 4 and the blade 2 respectively, and the rear disk 4 and the blade 2 are connected through the rear disk connecting device 5. Before spot welding, the rear disk connecting device is used to facilitate the welding robot to reach into the impeller for welding.

[0026] Insert the blades into the middle disk, connect the blades to the front disk by spot welding, and then connect them to the rear disk by spot welding. The rear disk and the rear disk connecting device are not connected temporarily. The automatic welding robot reaches into the inner holes of the rear disk and the front disk, welds the blades in the middle, and when the welding is completed, welds them to the rear disk connecting device.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the utility model content within the protection scope of the utility model.
