Abstract
Description
Technical Field
[0001] This utility model relates to an assembly device, specifically a precision assembly device for an axial magnetic field motor rotor, belonging to the field of axial magnetic field motor technology. Background Technology
[0002] The rotor structure of an axial field motor mainly consists of a rotor core, magnets (permanent magnets), and a rotor support. Its function is to generate a constant magnetic field through the magnets, which interacts with the rotating magnetic field generated by the stator windings to drive the rotor to rotate and thus output mechanical torque. The precision of the axial field motor rotor has a significant impact on the motor's performance. Insufficient rotor precision (such as magnet positioning deviation, core machining dimensional errors, and poor rotor dynamic balance) will lead to uneven magnetic field distribution, causing problems such as increased torque fluctuations, decreased power factor, and distortion of the back electromotive force waveform, resulting in decreased motor output efficiency and increased energy consumption.
[0003] Currently, the installation of magnets in axial magnetic field motor rotors generally employs an adhesive bonding process, firmly fixing the magnets to the surface of the rotor disc. However, the lack of efficient positioning of the rotor disc during assembly is a significant drawback. As the foundation for magnet installation, the positioning accuracy of the rotor disc is crucial. Any deviation in the rotor disc's positioning directly affects the installation accuracy of the magnets, leading to misalignment between the magnets and the rotor disc, disrupting the uniformity of the magnetic field distribution within the motor, and impacting the overall performance of the motor. Therefore, a precision assembly device for axial magnetic field motor rotors is proposed. Utility Model Content
[0004] In view of this, the present invention provides a precision assembly device for an axial magnetic field motor rotor to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.
[0005] The technical solution of this utility model embodiment is implemented as follows: an axial magnetic field motor rotor precision assembly equipment includes a worktable, and a positioning component is provided in the worktable. The positioning component includes a turntable, an arc-shaped locking block, a drive rod, a drive disk, an arc-shaped groove, a positioning gear ring, a positioning gear, a drive motor, a drive gear, a servo motor, and a transmission gear ring.
[0006] The upper surface of the turntable has three sliding grooves. The drive rod is fixedly connected to the lower surface of the arc-shaped locking block. The bottom of the arc-shaped locking block is slidably connected to the inner wall of the sliding groove. The arc-shaped groove is opened inside the drive disk. The drive rod is slidably connected to the inner wall of the arc-shaped groove. The positioning gear ring is fixedly connected to the lower surface of the drive disk. The positioning gear is fixedly connected to the output shaft of the drive motor. The transmission gear ring is fixedly connected to the outer wall of the turntable. The drive gear is fixedly connected to the output shaft of the servo motor.
[0007] More preferably, the turntable is rotatably connected to the interior of the worktable, and the drive disk is rotatably connected to the lower surface of the turntable.
[0008] More preferably, the drive motor is mounted on the lower surface of the turntable via an L-shaped plate, and the outer side wall of the positioning gear is meshed with the outer side wall of the positioning gear ring.
[0009] More preferably, the servo motor is installed inside the worktable, and the outer wall of the drive gear is meshed with the outer wall of the transmission gear ring.
[0010] More preferably, a positioning post is fixedly connected inside the slide groove, and the arc-shaped locking block is slidably connected to the outer wall of the positioning post.
[0011] More preferably, the upper surface of the turntable is fitted with a rotor disk, and the inner wall of the arc-shaped locking block is fitted with the outer wall of the rotor disk.
[0012] More preferably, a material box is installed on the upper surface of the workbench, and a robotic arm is also installed on the upper surface of the workbench.
[0013] More preferably, the robotic arm is equipped with a mounting plate, an assembly cylinder is mounted on the upper surface of the mounting plate, and an assembly suction cup is mounted on the bottom end of the cylinder shaft of the assembly cylinder.
[0014] The present invention has the following advantages due to the adoption of the above technical solution:
[0015] This invention uses a drive motor to rotate a positioning gear, causing three arc-shaped locking blocks to move synchronously, thereby locking and limiting the rotor disc. At this time, the robotic arm drives the assembly cylinder to pick up the magnets in the material box, and then moves them to the designated assembly position. The assembly cylinder then pushes the magnets downward, thus assembling the magnets onto the rotor disc. Compared with the prior art, this invention can achieve locking and limiting the rotor disc through the cooperation of the drive motor, positioning gear, positioning gear ring, drive disc, and other structures. Because the three arc-shaped locking blocks move synchronously, the rotor can always be located in the center position of the turntable when locking and limiting the rotor, without any positional deviation, thus ensuring the installation accuracy of the magnets.

Detailed Implementation
[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0025] like Figures 1-4 As shown, this utility model embodiment provides a precision assembly equipment for an axial magnetic field motor rotor, including a worktable 31. A positioning component 101 is provided in the worktable 31. The positioning component 101 includes a turntable 11, an arc-shaped locking block 14, a drive rod 16, a drive disk 17, an arc-shaped groove 18, a positioning gear ring 19, a positioning gear 20, a drive motor 21, a drive gear 22, a servo motor 23, and a transmission gear ring 24.
[0026] The upper surface of the turntable 11 is provided with three sliding grooves 12. The drive rod 16 is fixedly connected to the lower surface of the arc-shaped locking block 14. The bottom of the arc-shaped locking block 14 is slidably connected to the inner wall of the sliding groove 12. The arc-shaped groove 18 is opened inside the drive disk 17. The drive rod 16 is slidably connected to the inner wall of the arc-shaped groove 18. When the drive disk 17 rotates, the drive rod 16 slides in the arc-shaped groove 18 under the drive of the arc-shaped groove 18. The drive rod 16 drives the arc-shaped locking block 14, so that the three arc-shaped locking blocks 14 can move synchronously, thereby realizing the locking and limiting of the rotor. Since the three arc-shaped locking blocks 14 move synchronously, when locking and limiting the rotor, the rotor can always be located in the center position of the turntable 11 without positional deviation, thus ensuring the installation accuracy of the magnet.
[0027] The drive motor 21 is mounted on the lower surface of the turntable 11 via an L-shaped plate. The outer side wall of the positioning gear 20 is meshed with the outer side wall of the positioning gear ring 19. The drive disk 17 is rotatably connected to the lower surface of the turntable 11. The drive motor 21 drives the positioning gear 20 to rotate. The positioning gear 20 drives the positioning gear ring 19 through its teeth. The positioning gear ring 19 drives the drive disk 17 to rotate, thereby achieving automatic locking and limiting of the rotor.
[0028] The positioning gear ring 19 is fixedly connected to the lower surface of the drive disk 17, the positioning gear 20 is fixedly connected to the output shaft of the drive motor 21, the transmission gear ring 24 is fixedly connected to the outer side wall of the turntable 11, and the drive gear 22 is fixedly connected to the output shaft of the servo motor 23. The servo motor 23 is installed inside the worktable 31, and the outer side wall of the drive gear 22 is meshed with the outer side wall of the transmission gear ring 24. The turntable 11 is rotatably connected to the inside of the worktable 31. The servo motor 23 drives the drive gear 22 to rotate, and the drive gear 22 drives the transmission gear ring 24 through its teeth. The transmission gear ring 24 drives the turntable 11, thereby adjusting the position of the rotor so that the magnets can be assembled at different positions on the rotor.
[0029] In one embodiment, a positioning post 13 is fixedly connected inside the slide groove 12, and an arc-shaped locking block 14 is slidably connected to the outer wall of the positioning post 13. Through the cooperation of the slide groove 12 and the positioning post 13, the position of the arc-shaped locking block 14 can be limited, so that the arc-shaped locking block 14 can slide along the positioning post 13.
[0030] In one embodiment, the upper surface of the turntable 11 is attached to the rotor disk 25, and the inner sidewall of the arc-shaped locking block 14 is attached to the outer sidewall of the rotor disk 25. Thus, with the cooperation of the three arc-shaped locking blocks 14, the position of the rotor disk 25 can be defined. When assembling the magnets onto the rotor disk 25, adhesive is applied to the rotor disk 25 in advance.
[0031] In one embodiment, a material box 33 is mounted on the upper surface of the workbench 31, and a robotic arm 32 is also mounted on the upper surface of the workbench 31. An assembly plate 34 is mounted on the robotic arm 32, and an assembly cylinder 35 is mounted on the upper surface of the mounting plate 34. An assembly suction cup 36 is mounted at the bottom end of the cylinder shaft of the assembly cylinder 35. The robotic arm 32 is connected to an external control system. The robotic arm 32 can drive the assembly cylinder 35 to move to a designated position. Under the drive of the robotic arm 32, the assembly cylinder 35 can move axially in the X, Y, and Z directions. The assembly cylinder 35 drives the assembly suction cup 36 to pick up the magnet in the material box 33. After moving to the designated position, the assembly cylinder 35 pushes the magnet downward to assemble the magnet. After deflating the assembly suction cup 36, the magnet at the next position can be assembled.
[0032] In operation, the rotor disk 25 is placed on the surface of the turntable 11. The drive motor 21 drives the positioning gear 20 to rotate. The positioning gear 20 drives the positioning gear ring 19 through its teeth. The positioning gear ring 19 drives the drive disk 17 to rotate. Under the drive of the arc groove 18, the drive rod 16 drives the arc locking block 14, which can make the three arc locking blocks 14 move synchronously, thereby achieving locking and limiting of the rotor disk 25. At this time, the robotic arm 32 drives the assembly cylinder 35 to pick up the magnet in the material box 33. After moving to the designated assembly position, the assembly cylinder 35 pushes the magnet downward, thereby assembling the magnet on the rotor disk 25. When the assembly suction cup 36 is deflated, the assembly cylinder 35 picks up a new magnet again. At the same time, the servo motor 23 drives the drive gear 22 to rotate. The drive gear 22 drives the transmission gear ring 24 through its teeth. The transmission gear ring 24 drives the turntable 11. The turntable 11 adjusts the position of the rotor disk 25 so that the magnet can be assembled at different positions on the rotor disk 25.
[0033] Compared with the prior art, this utility model can lock and limit the rotor disk 25 by cooperating with the drive motor 21, positioning gear 20, positioning gear ring 19, drive disk 17 and other structures. Since the three arc-shaped locking blocks 14 move synchronously, the rotor can always be located in the center position of the turntable 11 when locking and limiting the rotor, without any positional deviation, thus ensuring the installation accuracy of the magnet.
[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
