Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0030] Referring to Figure 1 - Figure 3 An embodiment provided by the present application: a motor winding stator core, comprising a shell 1 used to support the overall device, the inner wall of the shell 1 is inserted with a plurality of groups of sheet bodies 2 used to compose the stator core, the front surface of the sheet body 2 is provided with a positioning assembly 4 used to assist the manufacturer to stack the sheet body 2, the positioning assembly 4 comprises a through slot 41, the through slot 41 is arranged on the upper surface of the sheet body 2 and the number is four groups, the through slot 41 is a rectangular slot, the through slot 41 penetrates the upper and lower surfaces of the sheet body 2, the inner wall of two groups of through slots 41 is fixedly connected with a first positioning plate 42 used to assist positioning, the left and right ends of the first positioning plate 42 are both fixedly connected with a wing plate 43 used to limit the top space of the first positioning plate 42, the inner wall of the other two groups of through slots 41 is fixedly connected with a second positioning plate 44 used to cooperate with the first positioning plate 42 to realize positioning, the first positioning plate 42, the wing plate 43, the second positioning plate 44 and the sheet body 2 are all made of the same piece of material, compared with the prior art, more materials are not needed to be consumed.
[0031] Referring to Figure 2 - Figure 4, multiple groups of through grooves 41 are arranged in a rotating array with the center line of the sheet body 2 as the rotating axis, two groups of first positioning plates 42 are symmetrically arranged with the center line of the sheet body 2 as the symmetry axis, and the arrangement can ensure that the overall quality of the sheet body 2 is uniformly distributed when stacking. Two groups of wing plates 43 are arranged in an inclined manner, two groups of wing plates 43 are arranged in a V shape, and the inclination angles are the same. The total height of the wing plate 43 is designed, and when the two groups of sheet bodies 2 are attached, the upper surface of the wing plate 43 is flush with the upper surface of the upper sheet body 2. The upper surface of the first positioning plate 42 and the upper surface of the two groups of wing plates 43 together form a trapezoidal inclined surface, which can be used to position the second positioning plate 44. The second positioning plate 44 is arranged in a trapezoidal shape, and the second positioning plate 44 is matched with the trapezoidal inclined surface. Multiple groups of sheet bodies 2 are stacked in a 90° rotating staggered manner. When stacking, the upper sheet body 2 needs to be rotated by 90° and then inserted into the top end of the lower sheet body 2. In this way, the second positioning plate 44 of the upper sheet body 2 can be inserted into the trapezoidal inclined surface of the lower sheet body 2.
[0032] Referring to Figure 2 Figure 4 , the top end of the sheet body 2 is provided with multiple groups of wire through grooves 5 for the power line to pass through, and the multiple groups of wire through grooves 5 are arranged in a rotating array with the center line of the sheet body 2 as the rotating axis. The top end of the sheet body 2 is provided with a containing groove 46 for containing copper wire. The center position of the sheet body 2 is provided with a rotor groove 47 for the rotation of the rotor. The outer wall of the sheet body 2 is provided with a fixing groove 45 for positioning the shell 1 and the sheet body 2. The inner wall of the shell 1 is provided with a fixing column 3. When installing the sheet body 2, the fixing groove 45 needs to be aligned with the fixing column 3. In this way, after installation is completed, the stator core can be prevented from rotating inside the shell 1.
[0033] Working principle: when stacking, a group of sheet bodies 2 is first placed on the workbench, then a group of sheet bodies 2 is taken and rotated by 90°, so that the second positioning plate 44 of the upper sheet body 2 is aligned with the through groove 41 of the lower sheet body 2, and then the upper sheet body 2 and the lower sheet body 2 are inserted. In this way, one stacking is completed. After stacking is completed, the first positioning plate 42 inside the upper sheet body 2 can provide positioning for the stacking of the next group of sheet bodies 2. When stacking, if the upper and lower sheet bodies 2 are not aligned when stacking, the second positioning plate 44 of the upper sheet body 2 cannot be completely inserted into the inside of the first positioning plate 42 of the lower sheet body 2. At this time, the operator can rotate the upper sheet body 2 to align the upper sheet body 2 with the lower sheet body 2 to ensure that the second positioning plate 44 and the first positioning plate 42 of the lower sheet body 2 can be correctly attached.
