[0034] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are for the purpose of explanation of the present application, and are not to be understood as a limitation of the present application.

[0035] Reference is made to Figures 1-5 A hub motor assembling and disassembling tool according to embodiments of the present application is described below.

[0036] Reference is made to Figure 1 and Figure 2 Embodiments of the present application provide a hub motor assembling and disassembling tool, which comprises a base 10, a rotor support 20 and a stator support 30.

[0037] The base 10 is used to provide a platform to support the rotor support 20 and the stator support 30, facilitating the operation of workers.

[0038] The rotor support 20 is movably mounted on the base 10 along a first horizontal direction, and the rotor support 20 is provided with a rotor flange 24 and a pull claw 25, the axial direction of the rotor flange 24 extends along the first horizontal direction, and the rotor flange 24 and the pull claw 25 are respectively used to connect two ends of the rotor assembly 40 in the axial direction.

[0039] The rotor support 20 is used to provide a supporting force to support the rotor assembly 40, and when the rotor support 20 moves along the first horizontal direction, it can drive the rotor assembly 40 to move along the first horizontal direction. The rotor flange 24 is used to connect with the rotor assembly 40, and the rotor flange 24 can define the installation direction of the rotor assembly 40. By setting the axial direction of the rotor flange 24 to extend along the first horizontal direction, when the rotor assembly 40 is connected with the rotor flange 24, the axis of the rotor assembly 40 also extends along the first horizontal direction, so that when the rotor assembly 40 moves along the first horizontal direction, it also moves along its axial direction. By setting the rotor flange 24 and the pull claw 25 to connect the two ends of the rotor assembly 40 in the axial direction, the stability of the support of the rotor assembly 40 is improved, and the force on the rotor assembly 40 itself is more uniform, and the shell of the rotor assembly 40 is not easy to deform.

[0040] The stator support 30 is movably mounted on the base 10 along a second horizontal direction and is arranged at one side of the rotor support 20 in a first horizontal direction, and the stator support 30 is provided with a stator flange 34 for fixedly connecting with a stator assembly 50, the first horizontal direction and the second horizontal direction are at an angle, and the stator support 30 can be moved along the second horizontal direction to coaxial with the axis of the stator flange 34 and the axis of the rotor flange 24.

[0041] The stator support 30 is used to provide a supporting force for supporting the stator assembly 50, and when the stator support 30 is moved along the second horizontal direction, the stator assembly 50 can be driven to move along the second horizontal direction. By arranging the stator support 30 at one side of the rotor support 20 in the first horizontal direction, the rotor support 20 can be close to and away from the stator support 30 when moving along the first horizontal direction. The stator flange 34 is used to fixedly mount the stator assembly 50 on the rotor support 20, and it can be understood that the stator flange 34 is coaxially connected with the stator assembly 50, so that the axis of the stator flange 34 is the axis of the stator assembly 50. When the stator support 30 is moved along the second horizontal direction to coaxial with the axis of the stator flange 34 and the axis of the rotor flange 24, the rotor assembly 40 mounted on the rotor flange 24 is coaxial with the stator flange 341 mounted on the stator flange 34, so as to facilitate the assembly or disassembly of the rotor assembly 40 and the stator assembly 50.

[0042] Among them, the first horizontal direction and the second horizontal direction are both horizontal directions, and the angle between the first horizontal direction and the second horizontal direction is not limited, which is determined according to the installation requirement, and exemplarily, the first horizontal direction can be perpendicular to the second horizontal direction, so as to facilitate the tooling assembly and the calibration during use.

[0043] In actual implementation, when assembling the wheel hub motor, the rotor assembly 40 is installed on the rotor support 20, and the stator assembly 50 is installed on the stator support 30. In the process of installing the rotor assembly 40 and the stator assembly 50 on the tooling, the stator support 30 can be aligned with the rotor support 20 in the first horizontal direction or can be misaligned with the rotor support 20, so as to facilitate multi-station operation in actual operation, improve production efficiency, control the stator support 30 to move along the second horizontal direction until the stator assembly 50 on the stator support 30 is coaxial with the rotor assembly 40, and keep the stator support 30 fixed, control the rotor support 20 to move towards the stator support 30 until the stator assembly 50 enters the rotor assembly 40, and then fixedly connect the stator assembly 50 and the rotor assembly 40, so as to complete the assembly of the wheel hub motor. When disassembling the wheel hub motor, the stator assembly 50 of the wheel hub motor can be fixedly connected with the stator flange 34 first, the stator support 30 is moved along the second horizontal direction to the position corresponding to the rotor support 20, the rotor assembly 40 is connected with the rotor flange 24 and the pull claw 25, at this time, the rotor assembly 40 and the stator assembly 50 are relatively fixed, the connecting bolts 252 on the rotor assembly 40 and the stator assembly 50 are disassembled, and then the rotor support 20 is controlled to move away from the stator support 30 along the first horizontal direction, so that the rotor assembly 40 and the stator assembly 50 are separated. Under the constraint of the rotor support 20 and the stator support 30, the rotor assembly 40 and the stator assembly 50 are not easy to interfere with each other when assembling or disassembling, the interference amount is reduced, the product quality is improved, and the corresponding position can be adjusted by moving the rotor support 20 and the stator, the assembly precision can be ensured, and the operation is simple.

[0044] According to the wheel hub motor assembly and disassembly tooling provided in the embodiments of the present application, the movable rotor support 20 and the movable stator support 30 are arranged, the rotor assembly 40 is fixed on the rotor support 20 through the rotor flange 24 and the pull claw 25, the multi-point fixing has high stability and is not easy to deform, the stator assembly 50 is fixed on the stator support 30 through the stator flange 34, and the assembly or disassembly of the rotor assembly 40 and the stator assembly 50 is realized by moving the rotor support 20 and the stator support 30. The structure is simple, the cost is low, the operation difficulty is low, the operation stability is high, the probability of wear and deformation of the rotor assembly 40 during assembly is reduced, and the stability of the stator assembly 50 and the rotor assembly 40 during installation and disassembly can be improved.

[0045] In some embodiments, in order to improve the efficiency of the rotor flange 24 and the stator flange 34 pair and reduce the centering difficulty, the movement stroke of the stator support 30 in the second horizontal direction can be limited. When the stator support 30 moves to one end of the movement stroke, the stator flange 34 is coaxial with the rotor flange 24, the operation is simple, and the efficiency is high.

[0046] Please refer to Figure 1 andFigure 2 According to some embodiments of the present application, the rotor support 20 can include a rotor support plate 21, which can be perpendicular to the first horizontal direction, and the rotor flange 24 and the claw 25 can be connected to one side of the rotor support plate 21 facing the stator support 30; the stator support 30 can include a stator support plate 31, which can be arranged parallel to the rotor support plate 21, and the stator flange 34 can be connected to one side of the stator support plate 31 facing the rotor support plate 21.

Moreover, even if the stator support plate 31 moves along the second horizontal direction, because the stator support plate 31 remains parallel to the rotor support plate 21, the stator flange 34 is conveniently centered with the rotor flange 24.

[0048] Please refer to Figure 2 and Figure 3 According to some embodiments of the present application, the rotor flange 24 can include a limiting shaft 242 and a rotor flange 241 coaxially connected to one end of the limiting shaft 242, the rotor flange 241 can be connected to the rotor support plate 21, and the end of the limiting shaft 242 away from the rotor flange 241 can be used to limit the cooperation with the shoulder of the rotor assembly 40 close to one end of the rotor support plate 21.

[0049] The rotor flange 241 is connected to one end of the limiting shaft 242, and the rotor flange 241 can be integrally arranged with the limiting shaft 242. The rotor flange 241 can be fixedly connected to the rotor support plate 21 by bolts, so that the limiting shaft 242 is fixedly connected to the rotor support plate 21, so as to ensure that the limiting shaft 242 can provide sufficient support force. Wherein, the shell of the rotor assembly 40 is generally recessed to one side in the direction along its axis, and the bottom of the recess and the open edge of the recess constitute two end faces of the rotor assembly 40 along its axis, wherein the bottom of the recess is generally provided with an opening for the shaft to pass through, and the opening position is provided with a shoulder, and the end of the limiting shaft 242 away from the rotor flange 241 can be limited in cooperation with the shoulder, wherein the limiting shaft 242 can also limit the rotor in the radial direction when cooperating with the shoulder, thereby realizing the positioning of the axis of the rotor assembly 40 and the limiting in the axial direction through the limiting shaft 242.

[0050] Exemplarily, the limiting shaft 242 can be a hollow shaft, which ensures the structural strength while facilitating cooperation with the shoulder.

[0051] The claw portion 251 of the pull claw 25 is arranged at one end of the pull claw 25 away from the rotor support plate 21, and is movable in the first horizontal direction, and is used to abut and limit the end surface of the rotor assembly 40 away from the rotor support plate 21.

[0052] One end of the pull claw 25 is connected to the rotor support plate 21 and is arranged on one side in the radial direction of the rotor flange 24, so that the pull claw 25 can be connected to the end surface of the rotor assembly 40 away from the rotor support plate 21, wherein the claw portion 251 of the pull claw 25 is movable in the first horizontal direction, so that the pull claw 25 can be clamped at both ends in the axial direction of the rotor assembly 40 in cooperation with the limiting shaft 242, thereby fixing the rotor assembly 40.

[0053] Exemplarily, the pull claw 25 can include an extension rod extending in the first horizontal direction, one end of the extension rod is connected to the rotor support plate 21, and the claw portion 251 is arranged at the other end of the extension rod, and the claw portion 251 is moved in the first horizontal direction through the extension and contraction action of the extension rod, wherein a locking screw can be arranged on the extension rod, and the extension rod is locked by tightening the locking screw, thereby fixing the claw portion 251, and the extension rod is unlocked by loosening the locking screw, and can be extended and contracted.

[0054] It should be noted that the shape of the claw portion 251 of the pull claw 25 is not specifically limited, and is matched according to the shape of the shell of the rotor assembly 40, and the cross-sectional shape of the extension rod is also not limited, which can be circular, rectangular or other shapes.

[0055] Please refer to Figure 2 and Figure 3 According to some embodiments of the present application, the pull claw 25 can be provided in plurality, and the plurality of pull claws 25 can be distributed in the circumferential direction of the rotor flange 24, and the pull claw 25 can be movably arranged in the radial direction of the rotor flange 24.

[0056] The plurality of pull claws 25 are arranged to improve the connection strength of the rotor assembly 40 and improve stability, and the plurality of pull claws 25 can be uniformly distributed in the circumferential direction of the rotor flange 24 to ensure that the rotor assembly 40 is uniformly stressed. The number of pull claws 25 is not specifically limited and can be determined according to design requirements, which can be two, three, four or more, exemplarily, in Figure 3 and Figure 4 The pull claw 25 is provided with four.

[0057] The claw 25 can move along the radial direction of the rotor flange 24. By adjusting the position of the claw 25 on the rotor support plate 21, the diameter enclosed by the plurality of claws 25 can be changed, so that the claw 25 can be adapted to different models and different sizes of the rotor assembly 40. The rotor flange 24 can also be provided with a plurality of sizes, because the rotor flange 24 is connected to the rotor support plate 21 through the rotor flange 241, and it is relatively convenient to replace. When adapting to different models and different sizes of the rotor assembly 40, the corresponding size of the rotor flange 24 can be selected, so that the hub motor assembly and disassembly tool of the present application can adapt to different models and different sizes of the hub motor.

[0058] Please refer to Figure 3 and Figure 4 According to some embodiments of the present application, a plurality of through grooves 211 can be provided on the rotor support plate 21 and extend in the first horizontal direction. The plurality of through grooves 211 can be distributed along the circumferential direction of the rotor flange 24 and extend in the radial direction of the rotor flange 24. The end of the claw 25 can be fixedly connected to the rotor support plate 21 through the connecting bolt 252 penetrating the through groove 211.

[0059] The through groove 211 can be arranged in the rotor support plate 21 or extend to the edge of the rotor support plate 21. The radial dimension of the claw 25 is greater than the width of the through groove 211, so that the claw 25 cannot enter the through groove 211, ensuring that the claw 25 abuts against the surface of the rotor support plate 21. The connecting bolt 252 penetrates the through groove 211 from the side of the rotor support plate 21 away from the claw 25 and is threadedly connected to the claw 25. The nut of the connecting bolt 252 abuts against the surface of the rotor support plate 21 away from the claw 25. The claw 25 is relatively fixed to the rotor support plate 21 by tightening the connecting bolt 252. When it is necessary to adjust the position of the claw 25, the connecting bolt 252 is loosened and driven to move along the through groove 211.

[0060] The plurality of through grooves 211 can be uniformly distributed along the circumferential direction of the rotor flange 24, so that the claws 25 are uniformly distributed and have higher stability. It can be understood that the through groove 211 is spaced apart from the mounting position of the rotor flange 24 to ensure the structural strength of the rotor support plate 21.

[0061] In another embodiment, a plurality of extension rods extending in the radial direction of the rotor flange 24 can be arranged on the circumferential side of the rotor support plate 21. The plurality of extension rods are uniformly distributed along the circumferential direction of the rotor support plate 21. One end of the claw 25 close to the rotor support plate 21 can be provided with a through hole, and the through hole is arranged outside the extension rod, so that the claw 25 can move along the extension rod to adjust the position of the claw 25. The connecting bolt 252 extending into the through hole is arranged on the claw 25, so that the connecting bolt 252 can abut against and limit the extension rod to fix the claw 25.

[0062] Referring to Figure 2 and Figure 4 According to some embodiments of the present application, the stator flange 34 can include a connecting shaft 342, a stator flange 341 coaxially connected with two ends of the connecting shaft 342, and a mounting flange 343 connected with a side of the stator support plate 31 facing the rotor support 20. The stator flange 341 can be used to connect with the stator assembly 50.

[0063] The connecting shaft 342, the stator flange 341, and the mounting flange 343 can be integrally formed by welding or casting. The mounting flange 343 can be fixedly connected with the stator support plate 31 by bolts, so that the connecting shaft 342 and the stator flange 341 are fixed relative to the stator support plate 31. The stator flange 341 can be matched with studs of the stator assembly 50 and locked and fixed by nuts, so that the stator assembly 50 is fixed on the stator support plate 31.

[0064] In this way, the stator flange 34 is connected with the stator support plate 31 through the flange, which is simple to connect and disassemble. The stator flange 34 can also be provided in multiple sizes, so that different sizes of the stator flange 34 can be used when corresponding to different sizes and different models of the stator assembly 50, so that the wheel hub motor assembly and disassembly tool can be adapted to multiple models of the wheel hub motor.

[0065] Referring to Figure 2 According to some embodiments of the present application, the connecting shaft 342 can be hollow, and an inner spline can be arranged at one end of the connecting shaft 342 close to the stator support plate 31. A spline shaft 35 that can rotate can be arranged on a side of the stator support plate 31 close to the rotor support 20, and the spline shaft 35 can be connected with the inner spline.

[0066] The spline shaft 35 is arranged to facilitate the axial positioning of the stator flange 34. In addition, the spline shaft 35 that can rotate is arranged, so that the stator flange 34 can rotate relative to the stator support plate 31, thereby driving the stator assembly 50 to rotate. During assembly or disassembly, the stator flange 34 can be adjusted to a suitable position by rotating, so as to facilitate the assembly and disassembly of the wheel hub motor, and the practicability is higher. It can be understood that when the stator flange 34 rotates, the mounting flange 343 is not connected with the stator support plate 31. When the angle of the stator flange 34 is determined, the mounting flange 343 and the stator support plate 31 are connected by bolts. In order to facilitate the connection with the mounting flange 343, a plurality of connection holes can be arranged on the stator support plate 31, so as to adapt to mounting flanges 343 of different angles or different sizes.

[0067] The spline shaft 35 and the stator support plate can be provided with a bearing 36 therebetween, so as to improve the stability of the rotation of the spline shaft 35.

[0069] The part of the spline shaft 35 located on the side of the stator support plate 31 away from the rotor support 20 can be provided with a through hole, and the small shaft 37 can be installed in the through hole, so that the worker can hold the small shaft 37 to control the rotation of the spline shaft 35, thereby facilitating the adjustment of the angle of the stator assembly 50.

[0071] The number of the first support legs 22 and the second support legs 32 is not limited herein and can be two or more, for example, the first support legs 22 and the second support legs 32 can each be provided with two.

[0072] The two first support legs 22 are respectively arranged on both sides in the width direction of the rotor support plate 21 to improve the stability of the rotor support plate 21, wherein the two ends of the first support leg 22 can be respectively located on both sides of the rotor support plate 21 in the first horizontal direction, and the first inclined strut 23 can be connected between the end of the first support leg 22 and the surface of the rotor support plate 21 to strengthen the structural strength of the rotor support plate 21, thereby improving the stability of supporting the rotor assembly 40.
