[0040] Reference Figure 1 , Figure 2 The twisting fixture provided in the embodiment of the present application is mainly used in a twisting machine to twist the flat wire terminal 70 in a flat wire motor. The flat wire is made of copper wire that has been stripped, cut, and then coiled. Figure 1 The flat wire terminal 70 is then inserted into the stator of the flat wire motor through a wire insertion process, and then the flat wire terminal 70 is twisted into a shape through a flaring and twisting process. Figure 2 As shown. The flat wire motor has different requirements for the crown height H after the twisting head according to the different motor performance requirements. According to the final crown height H requirement, a stripping portion 71 is reserved at both ends of the flat wire terminal 70 during the stripping and cutting stage, and the length of the stripping portion 71 is L, and the length L of the stripping portion 11 is equal to the crown height H.

[0041] When manufacturing the twisting fixture, different numbers of flat wire terminals 70 are arranged on the motor according to different motor performance requirements. The flat wire terminals 70 can be arranged in two layers, four layers, six layers or eight layers. In this embodiment, the twisting fixture is described by taking the arrangement of six layers of flat wire terminals as an example.

[0042] like Figures 3 to 5In this embodiment, the twisting fixture includes six twisting dies, each of which is cylindrical and is sequentially mounted from outside to inside, namely, the first twisting die 10, the second twisting die 20, the third twisting die 30, the fourth twisting die 40, the fifth twisting die 50 and the sixth twisting die 60. The diameters of the plurality of twisting dies decrease from outside to inside, and the ratio of decrease of two adjacent twisting dies is the same, so as to ensure that the intervals between two adjacent circles of the six circles formed in the end are equal.

[0043] Reference Figure 6 , a plurality of first inner grooves 11 are spaced and evenly distributed at one end of the inner wall of the first twisting head mold 10. The first inner grooves 11 are connected inwardly, but not outwardly, and the first twisting head mold 10 side wall is still provided on the outside, that is, the plurality of first inner grooves 11 are arranged along the inner side of the side wall. Figure 7 The shape and size of the cross section of the first inner wire groove 11 match the shape and size of the cross section of the flat wire terminal 70, and the axial height of the first inner wire groove 11 is consistent with the length of the stripping portion 71 at each end of the flat wire terminal 70, so that the flat wire terminal 70 can be better positioned in the first inner wire groove 11 before twisting. In this embodiment, in order to better insert the flat wire terminal 70, a guide arc surface 80 is provided on one side wall of the first inner wire groove 11. A first connecting portion that can be connected to a first external drive assembly (not shown in the figure) is provided at the bottom of the other end of the first twisting mold 10 away from the first inner wire groove 11. Referring to Figure 5 and Figure 8 Specifically, the first connecting portion includes a first bottom plate 12 arranged at the bottom of the first twisting head mold 10, a first center hole 13 arranged on the first bottom plate 12, and a plurality of first connecting holes 14 evenly arranged around the first center hole 13 for connecting with an external first driving member. The first connecting hole 14 is connected to the external first bearing, and the first bearing is fixed on the first external driving component. In this way, the first twisting head mold 10 can be driven to rotate through the first external driving component.

[0044] Similarly, refer to Figure 6 , multiple first outer grooves 21 are spaced and evenly distributed at one end of the outer wall of the second twisting head mold 20. The first outer grooves 21 are connected outwardly, but not inwardly, and the inner side still has the side wall of the second twisting head mold 20, that is, multiple first outer grooves 21 are arranged along the outer side of the side wall. Figure 7 The cross-sectional shape and size of the first outer wire groove 21 match the cross-sectional shape and size of the flat wire terminal 70, and the axial height of the first outer wire groove 21 is consistent with the length of the stripping portion 71 at each end of the flat wire terminal 70, so that the flat wire terminal 70 can be better positioned in the first outer wire groove 21 before turning. In this embodiment, in order to better insert the flat wire terminal 70, a guide arc surface 80 is also provided on one side wall of the first outer wire groove 21. Figure 5 and Figure 8The second twisting head mold 20 is provided with a second connection part that can be connected to an external second driving member at the bottom of the other end away from the first external line groove 21. The second connection part includes a second bottom plate 22 provided at the bottom of the second twisting head mold 20, a second center hole 23 provided on the second bottom plate 22, and a plurality of second connection holes 24 provided around the second center hole 23 for connecting to an external second driving member. The plurality of second connection holes 24 are used to connect to an external second bearing, and the second bearing is fixed to a second external driving assembly, so that the second twisting head mold 20 can be driven to rotate by the second external driving assembly.

[0045] When the second twisting head mold 20 is sleeved on the first twisting head mold 10, the first inner wire groove 11 and the first outer wire groove 21 are arranged oppositely, and the second connection holes of the second twisting head mold 20 are exposed at the first center hole 13 of the first twisting head mold 10, so that the connection between the second twisting head mold 20 and the external second bearing is not hindered. When plugging in the wires, the outer flat wire terminal 70 is inserted into the first inner wire groove 11, and the second outer flat wire terminal 70 is inserted into the first outer wire groove 21.

[0046] Refer again Figure 8 Among the third twist head mold 30, the fourth twist head mold 40, the fifth twist head mold 50 and the sixth twist head mold 60 which are arranged from the outside to the inside, the third twist head mold 30 and the fifth twist head mold 50 have the same structure as the first twist head mold 10, and the fourth twist head mold 40 and the sixth twist head mold 60 have the same structure as the second twist head mold 20, except that the diameters of the twist head molds are different and the sizes of the center holes of the connecting parts are different. Therefore, the structures of each twist head mold are not described again.

[0047] In this embodiment, when the six twisting head molds are stacked in sequence, the center holes of the bottom connecting parts of the six twisting head molds are reduced in size from the outside to the inside, and the connecting holes of the inner twisting head mold are exposed at the center holes of the outer twisting head mold. Therefore, the six twisting head molds are connected to the external bearings through the corresponding connecting holes without interfering with each other, and the six twisting head molds are driven to rotate by different driving parts.

[0048] Reference Figure 4 When the six twisting dies are assembled, six layers of wire grooves are formed on the top, and the flat wire motor stator 90 with the wires inserted can be placed on it. The stripped parts 71 of the flat wire terminals 70 with the wires inserted on the stator are correspondingly inserted into different wire grooves. The flat wire motor stator 90 with the twisted head is as shown in FIG. Fig. 9 shown.

[0049] The embodiment of the present application also provides a twisting machine (not shown in the figure), including a frame, a twisting fixture arranged on the frame, and a driving component for driving the twisting fixture to rotate to twist the flat wire terminal 70. The twisting fixture is the aforementioned structure. The twisting dies in the twisting fixture may be two, four, six or eight, or more. The number of driving components is consistent with the number of twisting dies in the twisting fixture. The output ends of the multiple driving members are all connected to bearings. The multiple bearings are stacked in sequence and are respectively connected to the connecting parts of each twisting die. The rotation directions of the driving components of two adjacent twisting dies are opposite. The multiple twisting dies are driven to rotate from the outside to the inside in sequence by the corresponding driving components. Specifically for this embodiment, the six layers of coils of the flat wire motor stator are respectively inserted into the six twisted six-slot wire slots. When the first twisting die 10 rotates clockwise by a predetermined angle, the second twisting die 20 rotates counterclockwise by a predetermined angle, and then the third twisting die 30 rotates clockwise by a predetermined angle, the fourth twisting die 40 rotates counterclockwise by a predetermined angle, the fifth twisting die 50 rotates clockwise by a predetermined angle, and finally the sixth twisting die 60 rotates counterclockwise by a predetermined angle, thereby completing the coil twisting of the entire flat wire motor stator. Since the height of each wire slot is consistent with the length of the stripping portion 71 at both ends of the flat wire terminal 70, when each twisting die rotates, the stripping portion 71 of the flat wire terminal 70 in the wire slot is driven to rotate to form a twisted shape, and the final formed crown also reaches a predetermined height H (such as Figure 2 As shown in the figure, the subsequent head cutting process is omitted, which not only saves the cost of head cutting equipment, but also avoids the waste of shearing coils, improves production efficiency and greatly reduces production costs.

[0050] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
