Technical Field

[0001] This utility model relates to the technical field of motor assembly and disassembly, and more specifically, it relates to a device for assembling and separating motor stators and rotors. Background Technology

[0002] With the continuous development of electric vehicles, the power density of electric vehicle motors is also increasing. Compared with round wire motors, flat wire motors have a higher slot fill factor. The increased slot fill factor means that more copper wire can be filled with the same amount of space, generating a stronger magnetic field and further improving the power density. The assembly and separation of the stator and rotor is a crucial process step in the prototyping of flat wire motors. Because the rotor contains a large number of permanent magnets, the stator and rotor attract, rub against each other during assembly, causing the stator to warp, affecting the motor assembly quality and reducing production efficiency.

Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0028] Example: A device for assembling and separating the stator and rotor of an electric motor, see attached document. Figure 1 - Appendix Figure 4 The device includes a base 1, a lifting seat 3, and a clamping device 4. The base 1 is supported on the top of the motor rear cover, and the stator of the motor is located inside the motor rear cover. The base 1 is provided with a vertical mounting hole 11 that penetrates the base 1. The rotor is inserted into the stator by passing vertically through the mounting hole 11 from the top of the base 1. The lifting seat 3 is located above the base 1 and can slide in the vertical direction. The clamping device 4 is located at the bottom of the lifting seat 3 and is used to clamp the top of the rotor.

[0029] The base 1 is fixed to the top of the motor rear cover to position the stator through the base 1. Then, the rotor is clamped by the clamping device 4 to position the rotor. Then, the rotor is installed and removed by the up and down movement of the lifting seat 3. And because the lifting seat 3 moves in the vertical direction, it is not easy for the rotor to rub against the stator when entering and leaving the stator.

[0030] Specifically, this embodiment also includes a tray 2, which is disposed above the base 1. The tray 2 is provided with a support part for supporting the rotor. One end of the tray 2 is rotatably connected to the top of the base 1 via a vertical rod. The tray 2 can rotate to move the support part above the stator and to the outside of the base 1 by rotation.

[0031] When installing the rotor, rotate the support of tray 2 to the outside of base 1 to facilitate placing the rotor on the support of tray 2. Then rotate the rotor so that the support rotates above the corresponding stator, so that the clamping device 4 can clamp the rotor. When disassembling the rotor, when the clamping device 4 drives the rotor upward to detach from the stator and moves it to a position where the bottom of the rotor is higher than tray 2, rotate the support of tray 2 to the bottom of the rotor. Then, lower the lifting seat 3 to place the stator on the support of tray 2. After that, rotate tray 2 to rotate the support and the stator on the support to the outside of base 1, so that the rotor on the support can be removed.

[0032] Specifically, the clamping device 4 includes a sliding seat 41 and a clamping member 42. There are two sliding seats 41, which slide horizontally on the lifting seat 3 to move closer to each other and further away from each other. Each sliding seat 41 is fixedly connected to a clamping member 42 located below the lifting seat 3. The side of the two clamping members 42 that are close to each other is set in an arc shape so that the two clamping members 42 can move closer to each other to clamp the rotor.

[0033] Specifically, there are two clamping devices 4, and correspondingly, the base 1 is supported on the top of the rear cover of the two motors at the same time; the four sliding seats 41 of the two clamping devices 4 slide along the same horizontal straight line.

[0034] Specifically, this embodiment also includes a clamping rod 5, which is rotatably connected to the top of the sliding seat 41. The length direction of the clamping rod 5 is set along the sliding direction of the sliding seat 41, and the clamping rod 5 passes through the four sliding seats 41 along its own length direction. The connection between the clamping rod 5 and the sliding seat 41 is provided with an external thread that engages with the threaded sliding seat 41. The helical directions of the external threads that engage with the two sliding seats 41 of the same clamping device 4 are opposite.

[0035] By rotating the clamping rod 5, the two clamping devices 4 can clamp and release the rotor.

[0036] Specifically, two vertically arranged guide rods 12 are fixedly connected to the top of the base 1. The guide rods 12 pass through the lifting seat 3 in a vertical direction, and the lifting seat 3 slides vertically on the guide rods 12.

[0037] Specifically, a vertically oriented lead screw 13 is rotatably connected to the top of the base 1, and the lead screw 13 vertically passes through the lifting seat 3. A nut is rotatably connected to the lifting seat 3 and sleeved on the lead screw 13. The nut is threadedly engaged with the lead screw 13. There are two lead screws 13 and nuts. A lifting rod 14 is rotatably connected to the top of the lifting seat 3. The axis of the lifting rod 14 is horizontal. Two bevel gears are provided on the outside of the lifting rod 14. The two bevel gears mesh with two bevel gears on the outside of the two nuts respectively so that the rotation of the lifting rod 14 drives the two nuts to rotate. A handle is provided at one end of the lifting rod 14 to drive the lifting rod 14 to rotate.

[0038] Rotating the lifting rod 14 by the handle can simultaneously rotate the two nuts, thereby causing the lifting seat 3 to slide vertically on the two lead screws 13.

[0039] Specifically, a positioning pin 15 is provided on the base 1, which extends vertically through the base 1 and can be inserted into a threaded hole on the motor rear cover. The positioning pin 15 facilitates the positioning between the base 1 and the motor rear cover.
