DETAILED DESCRIPTION

[0019] The utility model discloses as shown in the drawing, a kind of inner diameter adjustable motor cooling shell, it designs the plate type section bar for the original cylinder section bar, by taking different lengths of plate, such asFigure 5 As shown, by pre-designing different lengths of the annular plate 1, and then using a rolling device to achieve the ring rolling forming, motor housings with different inner diameters can be formed.

[0020] like Figure 1 As shown, this type of adjustable inner diameter motor cooling housing includes an annular plate 1, and a flow guiding cavity 5 is provided inside the annular plate 1. The flow guiding cavity 5 is integrally formed with the annular plate, requiring no secondary processing. The flow guiding cavity 5 has high forming precision and high efficiency.

[0021] The annular plate 1 is welded and fixed with an inlet 2 and an outlet 21. After the annular plate 1 is rolled and formed, a welding line 3 is provided at the joint point. This welding line 3 can be formed by argon welding or by friction welding. Under normal circumstances, the inlet 2 and the outlet 21 are respectively set around the welding line 3. The guide cavity 5 at the end of the inlet 2 is connected to the inlet 2 and is used as an inlet guide cavity 51. The outlet 21 is connected to the guide cavity 5 at the other end and is used as an outlet guide cavity 52. With this structural design, since both the inlet guide cavity 51 and the outlet guide cavity 52 are located at the cross-section, the internal tanks on one side of the inlet guide cavity 51 and the outlet guide cavity 52 can be machined by milling. After machining, sealing plates 6 are placed inside the tanks to seal all the guide cavities 5 on the side of the welding line 3 and then welded. At this time, the entire guide cavity 5 system is closed. In this utility model, a through groove 8 is machined by milling on the other side of the welding line 3. The through groove 8 connects two adjacent guide cavities 5 in the area of ​​the welding line 3. The through groove 8 forms a U-shaped through-flow group 81 of the guide cavity. The two U-shaped through-flow groups 81 are connected to each other by a parallel groove 7. A sealing device is provided on the outside of the parallel groove 7.

[0022] In actual processing, the parallel groove 7 is set on the inner or outer side of the annular plate 1. In this embodiment, in order to keep the outer side of the motor housing clean, the parallel groove 7 is processed on the inner side of the annular plate 1. The sealing device is attached to the parallel groove 7 and welded into shape. After welding, it is ground flat. The forming of the parallel groove 7 and the sealing device mentioned above are all realized before the annular structure of the motor housing is formed.

Figure 5The plate body is formed, and then cutting devices are used to cut the plate body into different lengths. Then, motor housings with different inner diameters can be formed by rolling the profile. The motor housing manufacturing cost is reduced, the through hole in the motor housing is formed with the plate body, the processing efficiency is high, the precision is high, and the manufacturing cost is low. The motor housing is integrally formed by welding on the side surface, and no end cover is needed, so the motor housing is more simple.
