Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a stator winding shaping device. Background Art

[0002] New energy vehicle drive motors primarily consist of a stator, rotor, and housing. During stator production, the windings assembled within the stator core slots are often disorganized and severely inconsistent in size. To ensure proper operation and subsequent process steps, the windings assembled within the stator core slots must be shaped. This involves shaping and limiting the winding's inner diameter, height, and outer diameter. This ensures that each energized winding maintains a safe distance from other components, such as the end cap or rotor, during operation, ensuring the motor's electrical insulation performance.

[0003] In the prior art, the shape of the shaping tool is a cylinder with steps. The outer diameter of the larger cylinder is the required inner diameter of the winding, and the smaller cylinder is the inner diameter of the core. The tool is taken and installed through the center opening of the tool.

[0004] In the process of realizing the present utility model, the inventors found that there are at least the following problems in the prior art: when using the existing shaping tooling, the inner diameter of the winding needs to be manually knocked larger so that it can be placed in the tooling, which results in a longer shaping time and a more complicated operation process. Utility Model Content

DETAILED DESCRIPTION

[0036] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0037] Combine Figures 1 to 6 As shown, the present invention provides a stator winding shaping device 100. Stator windings can be categorized as flat wire windings or round wire windings based on the shape of the conductors. Both require shaping. The stator winding shaping device includes a bracket, an expansion ring, a cone sleeve 107, and a drive rod 105.

[0038] The bracket primarily serves as a support, supporting components such as the expansion ring, cone sleeve 107, and drive rod 105. The expansion ring is radially slidably connected to the bracket and arranged circumferentially, allowing radial movement. The outer surface of the expansion ring has a curved surface. When the expansion ring reaches its outward limit, the curved surfaces converge to form a cylindrical surface, the outer diameter of which is configured to match the standard inner diameter of the stator winding. To facilitate insertion of the expansion ring into the inner ring of the stator winding, the expansion ring is provided with a step, which divides the expansion ring into an upper, thicker section and a lower, thinner section. The thinner section has a smaller outer diameter, allowing for easy insertion into the inner ring of the stator winding. The thicker section, after expansion, has an outer diameter that matches the standard inner diameter of the stator winding after shaping. The height of the thicker section should be no less than the height of the stator winding to achieve comprehensive shaping of the stator winding. The number of expansion rings is designed based on actual needs and is not specifically limited. The shapes of the expansion rings can be the same or different. The cone sleeve 107 is provided in the middle of the expansion ring. The outer side surface of the cone sleeve 107 has an outer cone surface, and the inner side surface of the expansion ring also has an inner cone surface. The induction of labor can cause the expansion ring to produce radial movement through its axial movement. Exemplarily, the cone sleeve 107 is in the shape of a truncated cone. The driving rod 105 is connected to the cone sleeve 107. The driving rod 105 and the cone sleeve 107 can be integrally formed, welded, glued or threaded. The driving rod 105 provides a pushing force to the cone sleeve 107. For ease of operation, the upper end of the driving rod 105 extends out of the bracket. The axial movement of the driving rod 105 can be done manually or with a power source. The power source can be an air cylinder, an oil cylinder or an electric cylinder. The use of a power source can reduce the amount of manual labor and is conducive to automation.

[0039] According to the embodiment of the present invention, the stator winding shaping device is provided with an expansion ring, a cone sleeve, and a drive rod. Before the device is expanded, it can be placed in the inner ring of the stator winding. By moving the drive rod to control the axial movement of the cone sleeve, the cone sleeve radially pushes the expansion ring around it. After the expansion ring moves to the outermost limit position, the outer side surface of the expansion ring forms a cylindrical surface that is the standard inner diameter of the stator winding. This makes it convenient and easy to shape the stator winding without having to manually tap the inner diameter of the stator winding to enlarge it. Therefore, the stator winding shaping device according to the embodiment of the present invention has the advantages of high shaping efficiency and simple operation.

[0040] In some embodiments, the bracket includes a cover plate 101 and a base plate 102. The bottom surface of the cover plate 101 is slidably connected to the top end of the expansion ring. The top surface of the base plate 102 is slidably connected to the bottom end of the expansion ring. The cover plate 101 and the expansion ring can be connected in the form of a key and a slot. For example, if the cover plate is provided with a key, the expansion ring can be provided with a corresponding slot, or if the cover plate is provided with a slot, the expansion ring can be provided with a corresponding key. Similarly, the base plate 102 and the expansion ring can be connected in the form of a key and a slot. Multiple sliding rods 106 connect the cover plate 101 and the base plate 102. The sliding rods 106 pass through the tapered sleeve 107 and are slidably connected to the tapered sleeve 107. The multiple sliding rods 106 can limit the cover plate 101 and the base plate 102, thereby limiting the axial position of the expansion ring, while also providing radial positioning for the tapered sleeve 107. After the mounting hole of the tapered sleeve 107 is engaged with the sliding rods 106, the expansion ring can slide axially. The number of sliding rods 106 can be arbitrarily selected according to actual needs. Exemplarily, the number of the sliding rods 106 is four, which are arranged around the driving rod 105, and the limiting effect is good.

[0041] In some embodiments, combined Figure 3 and Figure 6 As shown, the bottom surface of the cover plate 101 is provided with several radially arranged strip grooves 1011, and the top surface of the base plate 102 is provided with an annular groove 1021. The length of the strip grooves 1011 and the width of the annular groove 1021 limit the radial movement range of the expansion ring. The cover plate 101 also has a first mounting hole 1012 and a second mounting hole 1013. The first mounting hole 1012 is used to mount the sliding rod 106, and the second mounting hole 1013 is used to mount the driving rod 105. To save space, the first mounting hole 1012 can intersect with the strip grooves 1011. If the expansion rings are of the same shape, gaps will form between them after expansion. Some scattered enameled wires of the round winding may be squeezed into the expansion rings during expansion. When the expansion rings retract, the gaps may cause compression damage to the enameled wires. To solve this problem, the expansion rings include a plurality of outer expansion rings 103 and inner expansion rings 104, which are spaced apart from each other. The outer expansion ring 103 and the inner expansion ring 104 have different shapes. The outer expansion ring 103 and the inner expansion ring 104 always keep in contact with each other during the expansion or contraction process without generating any gap.

[0042] The top of the outer expansion ring 103 is provided with a first key 1031 adapted to the strip groove 1011, and the top of the inner expansion ring 104 is provided with a second key 1041 adapted to the strip groove 1011. The arrangement direction of the first key 1031 and the second key 1041 is consistent with the direction of the strip groove 1011.

[0043] The outer expansion ring 103 has a first support portion 1034 on the side near the tapered sleeve 107. The lower side of the first support portion 1034 has an inner conical surface that matches the conical surface of the tapered sleeve 107. A first arcuate groove 1036 is provided at the bottom of the outer expansion ring 103. The inner expansion ring 104 has a second support portion 1046 on the side near the tapered sleeve 107. The lower side of the second support portion 1046 has an inner conical surface that matches the conical surface of the tapered sleeve 107. A second arcuate groove 1042 is provided at the bottom of the inner expansion ring 104. Both the first arcuate groove 1036 and the second arcuate groove 1042 are plugged into the annular groove 1021 to limit the radial displacement of the expansion ring.

[0044] Specifically, the inner and outer sides of the first arcuate groove 1036 are respectively formed by the first outer expansion ring wall plate 1032 and the second outer expansion ring wall plate 1033. The length of the second outer expansion ring wall plate 1033 is shorter than that of the first outer expansion ring wall plate 1032. The inner and outer sides of the second arcuate groove 1042 are respectively formed by the first inner expansion ring wall plate 1043 and the second inner expansion ring wall plate 1044. The first outer expansion ring wall plate 1032 and the first inner expansion ring wall plate 1043 are located within the annular groove 1021. The inner and outer sides of the annular groove 1021 are respectively formed by the first annular groove wall plate 1022 and the second annular groove wall plate 1023. The first support portion 1034 and the second support portion 1046 both contact the cone sleeve 107, transmitting the radial movement force to the expansion ring. The side surfaces of the first outer expansion ring wall plate 1032, the second outer expansion ring wall plate 1033, the first inner expansion ring wall plate 1043, the second inner expansion ring wall plate 1044, the first annular groove wall plate 1022, and the second annular groove wall plate 1023 are all arcuate surfaces, and the centers of these arcuate surfaces are concentric. It should be noted that the first support portion 1034 and the second support portion 1046 are separated after the expansion ring is expanded, and after the expansion ring is contracted, the first support portion 1034 and the second support portion 1046 can be separated or in contact.

[0045] In some embodiments, the outer expansion ring 103 has inner walls 1035 on both sides of the first support portion 1034. The sidewalls of the inner expansion ring 104 include a first sidewall 1045 and a second sidewall 1047, which are connected. The first sidewall 1045 and the second sidewall 1047 are arranged at an angle, and the first sidewall 1045 contacts the inner wall 1035. Whether the expansion ring is retracted or expanded, the first sidewall 1045 and the inner wall 1035 maintain seamless contact. This prevents scattered enameled wire from the round winding from being squeezed in during the expansion of the expansion ring, thereby preventing scratches and compression of the enameled wire.

[0046] The stator winding shaping device also includes an elastic member 108. The drive rod 105 passes through the tapered sleeve 107, which is threadedly connected to the drive rod 105. One end of the elastic member 108 abuts the cover plate 101, and the other end of the elastic member 108 abuts the tapered sleeve 107. The function of the elastic member 108 is to force the tapered sleeve 107 away from the cover plate 101 when the outer diameters of the inner expansion ring 104 and the outer expansion ring 103 are reduced, preventing the tapered sleeve 107 from slipping and rotating with the drive rod 105. The elastic member 108 can be installed at any position between the cover plate 101 and the tapered sleeve 107. The elastic member 108 can be a spring, an elastic washer, an elastic pin, or the like. In one example, the elastic member 108 is a spring that is mounted within the drive rod 105 and effectively prevents the tapered sleeve from slipping and rotating.

[0047] like Figure 7 As shown, the stator winding shaping device 100 of the above embodiment operates as follows: the inner and outer expansion rings in the shaping device can be radially contracted. In the retracted state, the outer diameter of the working surface formed by their side surfaces is reduced. Since the outer diameter of the expansion rings is significantly smaller than the inner diameter of the stator winding 201 and the stator core 202, the shaping device can be easily and smoothly inserted into the stator winding 201 to be shaped. After the shaping device is inserted, the driving rod 105 is simply rotated again, causing the cone sleeve 107 to expand the inner and outer expansion rings 104, 103, and expand and maintain the inner diameter of the stator winding 201, completing the stator winding shaping function.
