[0034] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0035] Reference below Figure 1-Figure 4 A stator coil shaping tool 100 according to an embodiment of the present invention is described.

[0036] Reference Figure 1 and Figure 2 As shown, the shaping tool 100 of the stator coil of the embodiment of the present invention includes: an outer sleeve 10, an inner mold core 20, a base 40, a pressing assembly 50 and a coring assembly 60. The inner mold core 20 is arranged in the outer sleeve 10, and the inner mold core 20 is arranged at a distance from the outer sleeve 10. A receiving space 30 for accommodating the stator is formed between the outer sleeve 10 and the inner mold core 20. The base 40 can be detachably arranged in the receiving space 30, and the base 40 is located at one end of the receiving space 30. The pressing assembly 50 can be detachably arranged in the receiving space 30, and the pressing assembly 50 is located at the other end of the receiving space 30, so that pressure can be applied to the stator coil. The coring assembly 60 can be detachably arranged in the outer sleeve 10, and the coring assembly 60 is selectively connected to the inner mold core 20, so that the inner mold core 20 can be removed from the stator.

[0037] Specifically, traditional stator coils are generally shaped manually, which is not only time-consuming but also fails to meet the size requirements of the stator coils. In addition, the consistency of the size of the coil ends after shaping is poor, which can cause uneven heating of the stator when the motor is running, resulting in local overheating.

[0038] Therefore, it is necessary to optimize the stator coil shaping tool 100. The inner mold core 20 and the outer sleeve 10 in the stator coil shaping tool 100 are arranged at intervals, so that a receiving space 30 can be formed between the inner mold core 20 and the outer sleeve 10, thereby providing a receiving space 30 for the stator. Moreover, the stator is located between the outer sleeve 10 and the inner mold core 20. The outer sleeve 10 and the inner mold core 20 can generate pressure on both sides of the stator, thereby limiting the stator and further improving the consistency of the stator coil size. In addition, the base 40 is detachably arranged in the receiving space 30, so that the installation and removal of the inner mold core 20 can be facilitated.

[0039] Furthermore, the base 40 is located at one end of the accommodating space 30, and the pressing assembly 50 is located at the other end of the accommodating space 30, so that the base 40 and the pressing assembly 50 are arranged relatively spaced apart, and the stator is located between the base 40 and the pressing assembly 50. The base 40 can not only provide support for one end of the stator coil, but also serve as a lower pressure head of the stator. After the base 40 is installed in a predetermined position, it can generate pressure on one end of the stator coil. Only by adjusting the position of the pressing assembly 50 relative to the stator coil, the pressing assembly 50, as the upper pressure head of the stator, can apply pressure to the other end of the stator coil, thereby realizing the shaping of the two ends of the stator coil and improving the consistency of the dimensions of the two ends of the stator coil.

[0040] In addition, the coring assembly 60 can be detachably arranged on the outer sleeve 10, so that the coring assembly 60 and the outer sleeve 10 can be easily installed and removed. The coring assembly 60 is selectively connected to the inner mold core 20, that is, when the stator coil needs to be shaped, the coring assembly 60 is separated from the inner mold core 20. After the stator coil shaping is completed, the pressing assembly 50 is removed, and then the coring assembly 60 is connected to the inner mold core 20, so that the inner mold core 20 can be easily removed and the speed of removing the inner mold core 20 from the stator can be increased.

[0041] Therefore, the stator coil shaping tool 100 can realize the shaping of the two ends of the stator coil, ensure the consistency of the dimensions of the two ends of the stator coil, facilitate the removal of the inner mold core 20, and increase the speed of removing the inner mold core 20 from the stator.

[0042] According to some embodiments of the present invention, Figure 2 As shown, the outer sleeve 10 includes: a first cylinder 11 and a second cylinder 12, the first cylinder 11 and the second cylinder 12 are arranged along the axial direction of the outer sleeve 10, the base 40 is arranged on the first cylinder 11, and the pressing assembly 50 is arranged on the second cylinder 12.

[0043] Among them, the outer sleeve 10 is mainly composed of a first cylinder 11 and a second cylinder 12, and the first cylinder 11 and the second cylinder 12 are arranged along the axial direction of the outer sleeve 10. The first cylinder 11 can provide an installation space for the base 40, and the second cylinder 12 can provide an installation space for the pressing assembly 50, which is not only convenient for disassembly, but also convenient for the installation of the stator coil and the inner mold core 20.

[0044] According to some embodiments of the present invention, Figure 2 As shown, a first stop surface 111 is provided in the first cylinder 11, and a second stop surface 121 is provided in the second cylinder 12. The stator coil shaping tool 100 also includes: a first gasket 70 and a second gasket 80. The first gasket 70 abuts against the first stop surface 111, and the second gasket 80 abuts against the second stop surface 121. The first gasket 70 and the second gasket 80 are respectively clamped at both ends of the stator core 13 of the stator.

[0045] The inner wall of the first cylinder 11 is provided with a step groove, which can facilitate the formation of the first stop surface 111 . Correspondingly, the inner wall of the second cylinder 12 is also provided with a step groove, which can facilitate the formation of the second stop surface 121 .

[0046] In addition, a first gasket 70 is provided at the lower end of the stator core 13 of the stator, and a second gasket 80 is provided at the upper end of the stator core 13. The first gasket 70 and the second gasket 80 are respectively clamped at the two ends of the stator core 13 of the stator, so that the stator coil can be prevented from rubbing against the first cylinder 11 and the second cylinder 12, and damage to the stator coil can also be avoided.

[0047] Furthermore, a first stop surface 111 is provided in the first cylinder 11 , which not only allows the first cylinder 11 and the stator to be limited by the first gasket 70 , but also facilitates the positioning and installation of the first cylinder 11 and the stator by the first gasket 70 .

[0048] Similarly, a second stop surface 121 is provided in the second cylinder 12 , which not only allows the second cylinder 12 and the stator to be limited by the second gasket 80 , but also facilitates the positioning and installation of the second cylinder 12 and the stator by the second gasket 80 .

[0049] According to a specific embodiment of the present invention, Figure 2 As shown, the first gasket 70 and the second gasket 80 are both annular, and both the first gasket 70 and the second gasket 80 include: a plurality of arc-shaped pieces, and the plurality of arc-shaped pieces are sequentially arranged along the circumference of the first gasket 70 or the second gasket 80 .

[0050] Specifically, the first gasket 70 is annular, so that the first gasket 70 can be conveniently disposed between the stator core 13 and the first cylinder 11. Similarly, the second gasket 80 is annular, so that the second gasket 80 can be conveniently disposed between the stator core 13 and the second cylinder 12.

[0051] In addition, the first gasket 70 and the second gasket 80 both include: a plurality of arc-shaped pieces, for example, the first gasket 70 can be composed of two semicircular pieces, and the second gasket 80 can also be composed of two semicircular pieces. During the installation process, the first gasket 70 can be directly clamped on one end of the stator core 13, and the second gasket 80 can be clamped on the other end of the stator core 13, and the first gasket 70 and the second gasket 80 cannot exceed the maximum outer circle of the stator, and then the stator core 13 with the first gasket 70 and the second gasket 80 installed is installed into the outer sleeve 10.

[0052] According to some embodiments of the present invention, Figure 2 As shown, the pressing component 50 includes: a fixing member 51, a pressing member 52 and a first operating member 53. The pressing member 52 is arranged on the fixing member 51. The pressing member 52 can be detachably arranged in the accommodating space 30. The first operating member 53 is arranged on the fixing member 51, so that the pressing member 52 can be installed and disassembled by the fixing member 51.

[0053] The pressing member 52 can be detachably arranged in the accommodating space 30 , so that it is convenient to install the pressing member 52 in the accommodating space 30 and also convenient to take the pressing member 52 out of the accommodating space 30 .

[0054] In addition, a first operating member 53 is arranged on the fixing member 51. Through the first operating member 53, the fixing member 51 can drive the pressing member 52 to shape the end of the stator coil, which has the advantage of saving labor and can also facilitate the removal of the pressing member 52 through the first operating member 53, thereby facilitating the installation and disassembly of the pressing member 52.

[0055] According to some embodiments of the present invention, the pressing member 52 can be detachably arranged on the fixing member 51, so that the pressing members 52 of different heights can be replaced, or the pressing assembly 50 also includes: an adjusting member, which is connected between the fixing member 51 and the pressing member 52, and the adjusting member adjusts the position of the pressing member 52 by adjusting its length between the fixing member 51 and the pressing member 52.

[0056] Among them, the pressing piece 52 can be detachably arranged on the fixing piece 51, and the fixing piece 51 can be provided with a countersunk hole to facilitate the insertion of the bolt. The pressing piece 52 is provided with a threaded hole, and the bolt passes through the countersunk hole of the fixing piece 51 and is threadedly matched with the threaded hole of the pressing piece 52, thereby facilitating the installation and disassembly of the pressing piece 52 and the fixing piece 51.

[0057] Moreover, the pressing piece 52 can be detachably arranged on the fixing piece 51, so that the pressing pieces 52 of different heights can be replaced to shape the stator coil. By replacing the pressing pieces 52 of different heights, a graded pressing method is formed, thereby ensuring that the stator coil does not rebound after shaping.

[0058] Alternatively, a slide rail is provided in the fixing member 51, and a slide groove is provided in the pressing member 52. The fixing member 51 and the pressing member 52 can slide together through the slide rail and the slide groove to facilitate adjusting the distance between the fixing member 51 and the pressing member 52, so that the pressing assembly 50 can form different heights.

[0059] Alternatively, the pressing component 50 also includes: an adjusting member, which is connected between the fixing member 51 and the pressing member 52, and the adjusting member can change the length between the fixing member 51 and the pressing member 52, that is, change the distance between the fixing member 51 and the pressing member 52, so that pressing members 52 of different heights can be formed.

[0060] For example, the adjusting member can be a screw, which passes through the fixing member 51 and the pressing member 52. Threaded holes are provided inside the fixing member 51 and the pressing member 52. In this way, the distance between the fixing member 51 and the pressing member 52 can be adjusted, thereby changing the height of the pressing assembly 50.

[0061] According to some embodiments of the present invention, Figure 2 As shown, the inner mold core 20 includes: a first mold core 21, a second mold core 22 and a fastener 90. The first mold core 21 and the second mold core 22 are stacked along the axial direction of the inner mold core 20. The fastener 90 passes through the first mold core 21 and the second mold core 22, so that the first mold core 21 and the second mold core 22 can be detachably connected.

[0062] The first mold core 21 and the second mold core 22 are stacked along the axial direction of the inner mold core 20, so that the axial direction of the stator can be limited. The fastener 90 passes through the first mold core 21 and the second mold core 22, which can facilitate the installation and removal of the first mold core 21 and the second mold core 22.

[0063] According to some embodiments of the present invention, the coring assembly 60 includes: a coring cap 61, a threaded disassembly member 62 and a second operating member 63. The coring cap 61 can be detachably disposed on the outer sleeve 10, the threaded disassembly member 62 can be rotatably disposed on the coring cap 61, the threaded disassembly member 62 is suitable for being threadedly connected to one of the first core mold 21 and the second core mold 22 after the fastener 90 is separated from the first core mold 21 and the second core mold 22 respectively, and the second operating member 63 is connected to the threaded disassembly member 62.

[0064] Specifically, since a high-tonnage hydraulic press is required to operate during the shaping process, the stator coil is tightly fitted to the inner mold core 20 and is not easy to remove, so a core removal assembly 60 is provided.

[0065] The coring cap 61 can be detachably arranged on the outer sleeve 10. When the first core mold 21 needs to be removed, the pressing assembly 50 is first taken out, and then the coring assembly 60 is installed into the outer sleeve 10. The coring assembly 60 is installed at the upper end of the stator coil. By continuously rotating the second operating member 63, the threaded removal member 62 is screwed into the threaded hole of the first core mold 21 until the first core mold 21 is taken out, and then the whole is turned over, and the second core mold 22 at the other end of the stator coil is taken out in the same way.

[0066] According to some embodiments of the present invention, Figure 2 As shown, the coring assembly 60 further includes a bearing 64 , the bearing 64 is penetrated by a threaded disassembly member 62 , and the bearing 64 is located between the coring cap 61 and the second operating member 63 .

[0067] The bearing 64 is passed through the threaded disassembly member 62 . When the second operating member 63 rotates the threaded disassembly member 62 , the second operating member 63 can save more effort during the rotation due to the arrangement of the bearing 64 .

[0068] According to a specific embodiment of the present invention, Figure 2 and Figure 3As shown, the first mold core 21 is formed with a first through hole 23, and the second mold core 22 is formed with a second through hole 24, the end of the first mold core 21 away from the second mold core 22 is formed with a first countersunk groove 25, and the end of the second mold core 22 away from the first mold core 21 is formed with a second countersunk groove 26, and the fastener 90 includes: a screw rod 91 and a nut 92, the rod portion of the screw rod 91 is penetrated by the first through hole 23 and the second through hole 24, the head of the screw rod 91 is located in the first countersunk groove 25, the nut 92 is threadedly matched with the rod portion of the screw rod 91, and the nut 92 is located in the second countersunk groove 26.

[0069] Specifically, the first mold core 21 is formed with a first through hole 23, and the second mold core 22 is formed with a second through hole 24, which can facilitate the screw 91 to penetrate the first through hole 23 and the second through hole 24, so that the first mold core 21 and the second mold core 22 can form a whole.

[0070] Furthermore, the head of the screw 91 is located in the first groove 25, and the first groove 25 can limit the head of the screw 91. When the screw 91 is installed in place, the nut 92 is threadedly engaged with the rod of the screw 91, so that the connection between the first mold core 21 and the second mold core 22 can be made more stable and firm, and the installation and disassembly of the first mold core 21 and the second mold core 22 can also be facilitated.

[0071] Also, the specific installation steps are as follows:

[0072] First, place the first cylinder 11 on the working platform, install the base 40 into the first cylinder 11, and install the first gasket 70 and the second gasket 80 to the two ends of the stator core 13 respectively;

[0073] The stator core 13 of the assembled first gasket 70 and the second gasket 80 is installed into the first cylinder 11, the lower end of the stator contacts the base 40, and then the second cylinder 12 is installed. At this time, the assembled tooling is placed horizontally, the first mold core 21 and the second mold core 22 are installed from both ends respectively, and fixed with screws 91 and nuts 92, and then the assembly with the inner mold core 20 is placed vertically, and then the pressing assembly 50 is installed into the second cylinder 12 at the upper end, and finally, it is transferred to the press for shaping and pressing. After the pressing is completed, the pressing assembly 50 is removed and the core removal assembly 60 is installed, so that the first mold core 21 and the second mold core 22 can be disassembled.
