[0002] With new energy automobile, tank and unmanned aerial vehicle etc. field motor to stator slot full rate requirement is higher and higher, adopt previous winding, offline process has been unable to meet the requirements;

[0003] To improve stator offline slot full rate, the application of block type stator core structure is more and more extensive, and the slot full rate of this kind of stator winding is as high as 75-80%, which can well meet the problem that motor requires high slot full rate. Main features are: using automatic winding machine to concentrate winding on single block tooth core, then splicing single tooth core with winding into a whole circle;The disadvantage of this structure is that single tooth core needs to be spliced into a whole circle, and the splicing accuracy is difficult to control, especially when the outer diameter of the stator exceeds 300mm, the splicing accuracy is low, which is difficult to meet the design requirements. The device has high roundness accuracy, which can effectively solve the problem of low splicing accuracy of block type core.

[0004] Moreover, the device can also realize the function of rotating and drying after stator dip paint. In the past, after stator core dip paint, it was placed flat in the oven for drying and curing. During the curing process, the paint on the upper half of the stator would flow down, and the amount of paint hanging on the upper half of the stator was very small. The lower part hung too much paint, forming a paint tumor, which was difficult to handle and had an impact on the insulation performance of the motor. The rotating and drying process can rotate and dry the stator at the same time, making the paint hanging on the stator uniform and enhancing the electrical performance of the motor. SUMMARY

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0015] As Figure 1As shown, a device for both forming a segmented toothed iron core into a circle and for rotating and drying a stator after impregnation includes a base 1, a pad 2, an outer hoop 3, an inner circle fixing block 5, an inner circle push block 6, and a mandrel 8. The pad 2 and the mandrel 8 are positioned on the base 1 by pins and locked with screws. The outer hoop 3 is pre-tightened to the base 1 with screws. A segmented stator 4 coated with glue is placed on the inner circle step of the outer hoop 3. The inner circle fixing block 5 is installed on the inner side of the segmented stator 4 and the outer side of the mandrel 8. The inner circle push block 6 is positioned by the mandrel 8 and pre-tightened to the base 1 with screws. The inner circle push block 6 is pressed downward by the locking screws, thereby pushing the inner circle fixing block 5 outward until the outer circle of the inner circle fixing block 5 is in close contact with the inner stop of the base 1. Then the outer hoop 3 is locked. A roller 7 is selectively installed on the top of the mandrel 8 by screws.

The structural arrangement of the inner circle fixing block 5 and the inner circle push block 6 can provide support force inside the segmented stator 4, while also facilitating installation and improving the roundness accuracy.

[0017] Furthermore, such as Figure 2 As shown, the outer diameter of the roller 7 is set to be equal to the outer diameter of the base 1, which can ensure that the device of this utility model can be placed on the rotating shaft of the drying oven for rotation and drying.

[0018] The implementation method for forming a segmented stator: First, install the pad 2 and mandrel 8 on the base 1 using pins and tighten them with screws; then, pre-tighten the outer hoop 3 on the base 1 with screws, and place the segmented stator 4, coated with glue, onto the inner circular step of the outer hoop 3; then, place the inner circular fixing block 5 inside the segmented stator 4 and outside the mandrel 8, hoist in the inner circular push block 6, align the inner hole of the inner circular push block 6 with the outer circle of the mandrel 8, position it, and then slowly lower it. Press the inner circular push block 6 downward with the locking screws, thereby pushing the inner circular fixing block 5 outward until the outer circle of the inner circular fixing block 5 is flush with the inner stop of the base 1, thus completing the installation. Finally, tighten the outer hoop 3. After forming the stator, place it in an oven to dry and cure; finally, loosen the inner circular push block 6 and the outer hoop 3, remove the stator, and the forming process is complete.

[0019] Implementation method of rotating drying after stator impregnation: Reassemble the circular device according to the above steps, then hoist the impregnated stator core into the outer hoop 3, install the inner circle fixing block 5 and the inner circle push block 6, lock the outer hoop 3, and then lock the roller 7 onto the mandrel 8; finally, hoist the circular device together with the stator into the rotary drying oven, turn on the rotary drying function, and take out the stator after drying to complete the stator rotary drying work.
