Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of permanent magnet motors, and in particular to a tooling for embedding rotor magnets of a flat permanent magnet motor. Background Technology
[0002] In the field of motor manufacturing, especially in the assembly process of flat permanent magnet motors, the embedding of rotor magnets is a key process that has a direct impact on assembly accuracy, efficiency and product performance.
[0003] When inserting magnetic poles into a flat permanent magnet motor rotor, tooling is typically required for fixation and must allow for axial rotation. Existing tooling includes two support frames and a rigid rectangular bar fixedly connected to the two support frames. The rotor is supported by the rigid rectangular bar, which is then removed from the rotor's central shaft hole after assembly. However, this method suffers from poor rotor stability and is prone to damaging the central shaft hole due to the change in the rotor's center of gravity after magnet insertion. Furthermore, the rotor can only be assembled and disassembled relative to the horizontal extension of the rigid rectangular bar, hindering efficient assembly and disassembly in conjunction with other equipment. Utility Model Content

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a flat permanent magnet motor rotor magnet embedding fixture, which solves the technical problems in the prior art that the rotor has poor stability during the magnet insertion process due to the lack of a reliable connection structure, and that the rotor can only be disassembled and assembled relative to the horizontal extension direction of the rigid long square material, which is not conducive to the efficient disassembly and assembly of the rotor in conjunction with other equipment.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:
[0008] In a first aspect, this utility model provides a mounting fixture for a flat permanent magnet motor rotor magnet, comprising a frame, a swing arm, and a rotating head; one end of the swing arm is hinged to the frame along a first axis, and the axis of the swing arm in the length direction is perpendicular to the first axis; the other end of the swing arm is connected to the rotating head, and the center hole of the rotor is detachably connected to the rotating head, the rotating head establishing a rotational connection between the rotor and the swing arm along the axis of the swing arm in the length direction; the swing arm can swing along the first axis to enter a horizontal position and a vertical position; in the horizontal position, it can perform indexing and magnet insertion operations on the rotor; in the vertical position, it can assemble and disassemble the rotor relative to the rotating head.
[0009] In one technical solution of this utility model, a swing arm support and a rotor support are formed on the frame; in the horizontal position, the swing arm support can support the weight of the swing arm; in the vertical position, the rotor support can support the weight of the rotor.
[0010] In one technical solution of this utility model, the rotating head includes an inner sleeve and an outer sleeve. The inner sleeve is rotatably connected to the end of the swing arm along the length axis of the swing arm, and the outer sleeve is fixedly connected to the outer periphery of the inner sleeve. A connecting flange is formed on the inner sleeve, and the rotor is detachably connected to the connecting flange. The outer peripheral surface of the outer sleeve forms a contact surface. When the rotor is connected to the rotating head, the contact surface mates with the central hole of the rotor, and the outer peripheral surface of the inner sleeve remains detached from the central hole of the rotor.
[0011] In one technical solution of this utility model, the axial end of the rotor has a connecting hole, which is bolted to the connecting flange.
[0012] In one technical solution of this utility model, a limiting member connected to the frame is also included. The rotor has circumferentially distributed process holes. The limiting member can selectively penetrate the corresponding process holes to restrict the axial rotation of the rotor and the rotating head, thereby realizing rotor indexing during magnetization operation.
[0013] In one technical solution of this utility model, the limiting member includes a limiting rod connected to the frame, which can extend into or out of the process hole.
[0014] In one technical solution of this utility model, the limiting component also includes a sleeve, which is fixedly connected to the frame, and the limiting rod is axially slidably connected inside the sleeve, so that the limiting rod can slide into the process hole or slide out of the process hole.
[0015] In one technical solution of this utility model, the limiting member further includes an elastic member, which stores force when the limiting rod slides out of the process hole, so as to keep the limiting rod in the tendency to slide into the process hole.
[0016] In one technical solution of this utility model, a swing drive component supported on the frame is also included to drive the swing arm to swing and switch between a horizontal position and a vertical position.
[0017] (III) Beneficial Effects
[0018] The beneficial effects of this utility model are as follows: The mounting fixture for the rotor magnet of the flat permanent magnet motor of this utility model has a swing arm that can switch between a horizontal and a vertical position, greatly improving the applicability and work efficiency of the equipment. When the swing arm is in the horizontal position, the rotor is also in a suitable posture for indexing and magnet insertion operations, which makes it easy for operators to accurately embed the magnet into the predetermined position of the rotor, improving assembly accuracy and consistency. When it is necessary to replace or repair the rotor, simply switch the swing arm to the vertical position, and the rotor can be easily disassembled or installed with the help of devices including lifting tools, significantly reducing the difficulty of operation and labor intensity.
[0019] The rotor is rotatably connected to the swing arm via a rotating head. Therefore, even if the rotor's center of mass changes after magnetization, the rotor's stability can be effectively guaranteed compared to the simple plug-in structure in existing technologies, and damage to the rotor's central hole due to uneven force can be avoided.
[0020] This technical solution, through the adjustable angle of the swing arm, enables rapid switching of the rotor between different operating states, improving production efficiency. Furthermore, the solution boasts a simple and reliable structure, low maintenance costs, and strong adaptability, suitable for assembling various specifications of flat permanent magnet motor rotors. Simultaneously, leveraging the rotational capability of the rotating head, the rotor angle can be flexibly adjusted during magnet insertion, further enhancing assembly quality and process level. Overall, this tooling not only simplifies the assembly process but also enhances operational safety and convenience, possessing significant potential for widespread application.

[0033] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-6 The present invention will be described in detail through specific embodiments.
[0034] Example 1:
[0035] Reference Figures 1-6 This utility model provides an inlay fixture for a flat permanent magnet motor rotor magnet, including a frame 1, a swing arm 2, and a rotating head 3. One end of the swing arm 2 is hinged to the frame 1 along a first axis, and the length axis of the swing arm 2 is perpendicular to the first axis. The other end of the swing arm 2 is connected to the rotating head 3. The center hole of the rotor 100 is detachably connected to the rotating head 3. The rotating head 3 establishes a rotational connection between the rotor 100 and the swing arm 2 along the length axis of the swing arm 2. The swing arm 2 can swing along the first axis to enter a horizontal position and a vertical position. In the horizontal position, it can perform indexing and magnet insertion operations on the rotor 100. In the vertical position, it can detach and install the rotor 100 relative to the rotating head 3.
[0036] In this embodiment, one end of the swing arm 2 is hinged to the frame 1 along the first axis, ensuring that it can swing flexibly. At the same time, the axis of the swing arm 2 itself remains perpendicular to the first axis, thus providing a stable spatial motion basis for the entire device. The rotor 100 can rotate freely around the axis of the swing arm 2 to meet the needs of different angle adjustments.
[0037] The swing arm 2 can switch between horizontal and vertical positions, greatly improving the applicability and work efficiency of the equipment. When the swing arm 2 is in the horizontal position, the rotor 100 is also in a suitable posture for indexing and magnet insertion operations, which makes it easy for operators to accurately embed the magnet into the predetermined position of the rotor 100, improving assembly accuracy and consistency. When it is necessary to replace or repair the rotor 100, simply switch the swing arm 2 to the vertical position, and the rotor 100 can be easily disassembled or installed with the help of devices including lifting tools, which significantly reduces the difficulty of operation and labor intensity.
[0038] The rotor 100 is rotatably connected to the swing arm 2 via the rotating head 3. Therefore, even if the center of mass of the rotor 100 changes after magnetization, compared with the simple plug-in structure in the prior art, the stability of the rotor 100 can be effectively guaranteed, and the central hole of the rotor 100 can be prevented from being damaged due to uneven force.
[0039] This technical solution, through the angle adjustment function of the swing arm 2, enables rapid switching of the rotor 100 in different working states, improving production efficiency. Furthermore, the solution features a simple and reliable structure, low maintenance costs, and strong adaptability, suitable for assembling various specifications of flat permanent magnet motor rotors 100. Simultaneously, utilizing the rotational capability of the rotating head 3, the rotor 100 angle can be flexibly adjusted during magnet insertion, further enhancing assembly quality and process level. Overall, this tooling not only simplifies the assembly process but also enhances operational safety and convenience, possessing significant potential for widespread application.
[0040] Specifically, the rotor's 100-point rotation process can be manually operated by the worker. When it is necessary to switch the position of the swing arm 2, a lifting device can be used to lift the swing arm 2 to achieve the angle switch of the swing arm 2, thereby enabling it to switch between horizontal and vertical positions and reducing the workload.
[0041] Example 2:
[0042] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0043] The frame 1 has a swing arm support 1a and a rotor support 1b. In the horizontal position, the swing arm support 1a can support the weight of the swing arm 2. In the vertical position, the rotor support 1b can support the weight of the rotor 100.
[0044] In this embodiment, when the swing arm 2 is switched to the horizontal position for indexing and magnetization, the swing arm support 1a can effectively bear its own weight, avoiding structural fatigue or displacement caused by long-term suspension, thereby ensuring accuracy and stability during operation.
[0045] When the swing arm 2 is adjusted to a vertical position for disassembly or installation of the rotor 100, the rotor support 1b can bear the weight of the rotor 100 itself. This not only reduces the load pressure on the rotating head 3 and the connecting parts, but also further ensures the safety of operators during loading and unloading, preventing risks such as accidental detachment. This design fully considers the rationality of the force distribution in actual use, so that the entire tooling maintains good mechanical performance and durability even when frequently switching working conditions.
[0046] By setting up a dedicated support structure, the overall service life of the tooling is extended and the frequency of daily maintenance is reduced. This not only improves operational safety and convenience but also increases assembly efficiency, especially in mass production, where it helps to achieve fast and continuous operation.
[0047] Example 3:
[0048] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0049] The rotating head 3 includes an inner sleeve 31 and an outer sleeve 32. The inner sleeve 31 is rotatably connected to the end of the swing arm 2 along the length axis of the swing arm 2. The outer sleeve 32 is fixedly connected to the outer periphery of the inner sleeve 31. A connecting flange 31a extends from the end face of the inner sleeve 31 away from the frame 1. The rotor 100 is detachably connected to the connecting flange 31a. The outer peripheral surface of the outer sleeve 32 forms a contact surface 32a. When the rotor 100 is connected to the rotating head 3, the contact surface 32a mates with the center hole of the rotor 100, and the outer peripheral surface of the inner sleeve 31 remains detached from the center hole of the rotor 100.
[0050] In this embodiment, the inner sleeve 31 is rotatably connected to the end of the swing arm 2, allowing the rotating head 3 to rotate flexibly around the axis of the swing arm 2. The two are connected by bearings. The outer sleeve 32 is fixedly installed on the outer periphery of the inner sleeve 31, forming an integral support structure to support the center hole of the rotor 100. A connecting flange 31a is formed on the inner sleeve 31. For example, the end of the inner sleeve 31 away from the frame 1 extends outward to form a connecting flange 31a, which is used for detachable connection with the rotor 100, facilitating quick clamping and replacement of rotors 100 of different specifications.
[0051] Specifically, the outer sleeve 32 is made of a non-rigid material, such as nylon, to reduce its impact on the accuracy of the center hole. The contact surface 32a can achieve a tight fit with the center hole of the rotor 100, thereby providing auxiliary support and radial restraint for the rotor 100 during magnet insertion, preventing positional displacement caused by vibration or external forces, and ensuring the accuracy and consistency of the magnet insertion position. At the same time, the outer peripheral surface of the inner sleeve 31 remains detached from the center hole of the rotor 100, avoiding unnecessary friction and interference, and thus preventing the inner sleeve 31 from damaging the accuracy of the center hole of the rotor 100.
[0052] Example 4:
[0053] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0054] The rotor 100 has a connecting hole 100a on its axial end, which is bolted to the connecting flange 31a. This connecting hole 100a is the original hole position on the rotor 100, which is used to fix the rotor 100 to other components during the assembly process. This tooling reuses this hole position as the connecting hole 100a position between the rotor 100 and the rotating head 3, realizing multiple uses for one hole, and avoiding the problem of setting additional connection structures on the rotor 100, which would damage the original structure of the rotor 100.
[0055] Bolted connections are not only simple in structure and easy to operate, but also have good repeatability, facilitating consistent assembly quality in multiple batches or continuous production. Furthermore, since the connecting flange 31a extends from the inner sleeve 31, it has high overall strength and good torsional resistance, making it less prone to deformation or loosening when transmitting torque, thus ensuring the stability and reliability of the rotor 100 during the indexing and magnetizing process.
[0056] The connecting flange 31a can be detachably connected to the inner sleeve 31. By replacing the connecting flange 31a with different specifications or adjusting the bolt arrangement, it can be adapted to various models of rotor 100 structures, expanding the application range of the tooling. Combined with the auxiliary support of the outer sleeve 32 contact surface 32a for the center hole of the rotor 100, the entire connection system provides a firm axial fixation while effectively avoiding radial offset and shaking during rotation.
[0057] Example 5:
[0058] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0059] It also includes a limiting member 4 connected to the frame 1. The rotor 100 has circumferentially distributed process holes 100b. The limiting member 4 can selectively penetrate the corresponding process holes 100b to restrict the axial rotation of the rotor 100 and the rotating head 3, thereby realizing the indexing of the rotor 100 during the magnetization operation.
[0060] The limiting component 4 makes the indexing control of the rotor 100 more precise and the operation more convenient during magnetization. The limiting component 4 is fixedly connected to the frame 1. Its function is to restrict the axial rotation between the rotor 100 and the rotating head 3 by cooperating with the existing circumferentially distributed process holes 100b on the rotor 100, thereby ensuring reliable positioning at different indexing positions and improving the stability of the rotor 100 during magnetization.
[0061] Specifically, when the rotor 100 is installed on the rotating head 3 and is in a horizontal working position, the operator can align the limiting member 4 and insert it into the process hole 100b on the rotor 100 corresponding to the position of the limiting member 4, according to the required insertion angle, so that the rotor 100 is mechanically locked at the preset angle position. Since these process holes 100b are evenly distributed along the circumference of the rotor 100, they can serve as ideal indexing reference points, eliminating the need for additional dedicated positioning structures, simplifying tooling design and improving adaptation efficiency.
[0062] With the detachable connection of the limiting component 4 to the rotor 100, the support of the outer sleeve 32 contact surface 32a, and the multi-angle adjustment of the swing arm 2, this tooling has strong versatility and is particularly suitable for high-precision, large-volume production of permanent magnet motors. It has good practical application value and promotion prospects.
[0063] Specifically, the first plane is a plane passing through the axis of the swing arm 2 and perpendicular to the first axis. This first plane is also the plane of symmetry of the rotor 100. During magnet insertion, the operation is always performed on the side of the rotor 100 corresponding to this first plane. Therefore, after the magnetic pole is inserted, the rotor 100 will rotate under gravity, allowing the limiting member 4 to restrict the rotation angle of the rotor 100. Thus, the gap between the limiting rod 41 of the limiting member 4 and the process hole 100b can be very large; it is only necessary to restrict the downward rotation of the rotor 100.
[0064] Example 6:
[0065] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0066] The limiting component 4 includes a limiting rod 41 connected to the frame 1, which can extend into or out of the process hole 100b. The limiting component 4 also includes a sleeve 42, which is fixedly connected to the frame 1. The limiting rod 41 is axially slidably connected to the sleeve 42, so that the limiting rod 41 can slide into or out of the process hole 100b.
[0067] In this embodiment, the sliding connection design allows the limiting rod 41 to flexibly adjust its position relative to the rotor 100. When the rotor 100 needs to be adjusted in angle, the operator or automated device pulls the limiting rod 41 out of the process hole 100b to release the lock. After the angle adjustment is completed, the limiting rod 41 is reinserted into the corresponding process hole 100b, so that the rotor 100 is reliably fixed at the current indexing position. Since the process hole 100b itself is uniformly distributed in the circumferential direction of the rotor 100, it can serve as an ideal indexing reference point, ensuring that the angle of the rotor 100 after each limiting action meets the design requirements.
[0068] Furthermore, this limiting structure also possesses excellent guiding properties and motion stability. The sliding path of the limiting rod 41 within the sleeve 42 is precisely constrained, preventing skewing or jamming and improving the overall smoothness of operation. Simultaneously, the exposed length of the limiting rod 41 can be reasonably set according to actual needs, ensuring sufficient insertion depth to provide reliable limiting force without affecting other operational processes such as rotor 100 loading / unloading and swing arm 2 position switching.
[0069] By cooperating with the limiting rod 41 and the process hole 100b, the indexing position of the rotor 100 is quickly and accurately locked, which significantly improves the consistency and assembly accuracy of the magnet insertion operation. Using the existing process hole 100b as the limiting reference, there is no need to process a special positioning structure, which simplifies the manufacturing process and reduces costs. The sliding connection between the limiting rod 41 and the sleeve 42 is simple in structure, easy to maintain, and highly adaptable, which can meet the limiting requirements of different models of rotor 100 and improve the versatility and flexibility of the tooling.
[0070] Furthermore, since the radial positions of the process holes 100b of different models of rotors 100 are inconsistent, in order to better adapt the limiting member 4 to different models of rotors 100, the position of the limiting member 4 can be set to an adjustable form, such as the limiting member 4 being vertically slidably connected to the frame 1 through a limitable slide rail assembly.
[0071] Example 7:
[0072] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0073] The limiting member 4 also includes an elastic member 43, which stores force when the limiting rod 41 slides out of the process hole 100b, so that the limiting rod 41 maintains its tendency to slide into the process hole 100b. Specifically, a contact portion can be radially extended on the limiting member 4, and the elastic member 43 can be set as a compression spring sleeved on the limiting member 4, with the two ends of the compression spring abutting against the contact portion and the axial end of the sleeve 42, respectively.
[0074] In this embodiment, the elastic element 43 enables the limiting rod 41 to have an automatic reset function, thereby significantly improving the convenience of operation and the reliability of positioning. When the operator or automated device pulls the limiting rod 41 out of the process hole 100b to release the locking of the rotor 100, the elastic element 43 is in a compressed state and continuously applies a restoring force. Once the external force is removed, the elastic element 43 pushes the limiting rod 41 to automatically reset, allowing it to quickly re-insert into the nearest process hole 100b, completing the repositioning of the rotor 100. This design effectively avoids the problems of operational omissions or inaccurate positioning that may occur in the manual reset method, improving the consistency and efficiency of the indexing and magnetizing operation.
[0075] The presence of the elastic element 43 further enhances the stability and response speed of the limiting action. Since the limiting rod 41 always tends to move into the process hole 100b, even slight vibrations or external disturbances during equipment operation ensure that the limiting rod 41 remains stably embedded in the hole, preventing angular displacement due to loosening and thus guaranteeing magnetic insertion accuracy. Simultaneously, this self-resetting structure reduces manual intervention steps, simplifies the operation process, and is particularly suitable for assembly scenarios requiring frequent switching of indexing angles.
[0076] Example 8:
[0077] Reference Figures 1-6 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:
[0078] It also includes a swing drive unit supported on the frame 1 to drive the swing arm 2 to swing and switch between horizontal and vertical positions.
[0079] In this embodiment, the swing drive is used to smoothly switch the swing arm 2 between horizontal and vertical positions, thereby achieving automated or semi-automated control of the assembly operation. Specifically, the swing drive is mounted on the frame 1 and forms a transmission connection with the swing arm 2. It can provide power output according to operational needs, driving the swing arm 2 to rotate around a first axis, allowing it to flexibly switch between a horizontal insertion position and a vertical loading / unloading position. This design effectively replaces the method of manually moving or using auxiliary tools to adjust the angle of the swing arm 2, which not only improves the operating efficiency of the equipment but also enhances the accuracy and consistency of the movements. The swing drive can adopt a structure such as a cylinder, hydraulic cylinder, or electric push rod, and the selection and configuration are based on the actual production environment and automation requirements. Its output end can achieve stable transmission with the swing arm 2 through a connecting rod, hinge, or other linkage mechanism, ensuring that the swing arm 2 runs smoothly and is accurately positioned during the switching process.

The mounting fixture for the rotor magnet of the flat permanent magnet motor as described in claim 5, characterized in that: The limiting member (4) includes a limiting rod (41) connected to the frame (1), the limiting rod (41) being able to extend into the process hole (100b) or exit the process hole (100b).
7. The mounting fixture for the rotor magnet of the flat permanent magnet motor as described in claim 6, characterized in that: The limiting member (4) also includes a sleeve (42), which is fixedly connected to the frame (1). The limiting rod (41) is axially slidably connected to the sleeve (42) so that the limiting rod (41) can slide into the process hole (100b) or slide out of the process hole (100b).
8. The mounting fixture for the rotor magnet of the flat permanent magnet motor as described in claim 7, characterized in that: The limiting member (4) also includes an elastic member (43), which stores force when the limiting rod (41) slides out of the process hole (100b) so that the limiting rod (41) maintains the tendency to slide into the process hole (100b).
9. The mounting fixture for the rotor magnet of a flat permanent magnet motor as described in any one of claims 1-8, characterized in that: It also includes a swing drive supported on the frame (1) to drive the swing arm (2) to swing and switch between the horizontal and vertical positions.
