Description

Technical Field

[0001] This utility model relates to the field of rotor assembly technology, specifically a tooling fixture for synchronous installation of magnets. Background Technology

[0002] In the field of motor manufacturing, the assembly of magnets and rotor cores is one of the core processes, and its precision and efficiency directly affect the performance, reliability, and production cost of the motor. Traditional magnet installation methods mainly rely on manual operation or simple tooling, which is difficult to meet the high-quality and high-efficiency requirements of modern motor production.

[0003] Existing magnet blocks are small in size and need to be precisely inserted into the magnet slots of the rotor core. When operating manually, operators need to adjust the position of the magnets visually or with simple measuring tools. This can easily lead to magnet tilting, offset, or uneven gaps due to visual fatigue, hand tremors, or insufficient accuracy of the measuring tools. When installing magnets with traditional simple tooling, magnets usually need to be installed one by one. The positioning of each magnet depends on the installation result of the previous one. If there is a slight deviation in the previous magnet, the deviation of the subsequent magnets will be amplified step by step, eventually leading to uneven distribution of magnetic poles in the rotor core, causing quality problems such as motor torque fluctuations, increased noise, and even magnet detachment.

[0004] Meanwhile, manual operation or simple tooling cannot meet the synchronization requirements, that is, multiple magnets need to arrive at the designated position at the same time to avoid interference between magnetic poles caused by sequential installation. Without synchronous constraints on multiple magnets, the magnets may attract or repel each other due to magnetic force during installation, which further aggravates the positioning deviation, resulting in poor installation accuracy and low installation efficiency.

[0005] Therefore, in order to address the above problems, the applicant needs to design a tooling fixture for the synchronous installation of magnets. Utility Model Content

[0006] The purpose of this invention is to provide a tooling fixture for synchronous installation of magnets, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for synchronous installation of magnets, comprising a base plate, wherein the base plate is provided with an installation groove for installing a rotor core, and further comprising a clamping component disposed above the base plate, wherein the clamping component is used to push the magnet blocks into the magnet groove of the rotor core, the clamping component comprising a base connected to the base plate, wherein a rotating disk is rotatably disposed above the base, wherein a guide groove is provided on the rotating disk, wherein a guide rod is disposed in the guide groove, wherein a pusher is rotatably disposed on the guide rod, and wherein the pusher is used to push several magnet blocks to move synchronously, wherein a lower guide plate is disposed above the rotating disk, wherein a lower slot is provided on the lower guide plate, and the lower slot is located outside the guide rod.

[0008] Furthermore, a mounting frame is fixedly installed above the base plate, and a placement groove is provided on the mounting frame, with a magnetic block placed in the placement groove.

[0009] Through the above structural design, the placement slot provides a precise and consistent initial positioning reference for all the magnet blocks to be installed.

[0010] Furthermore, the mounting bracket and the mounting groove are concentric and coaxial.

[0011] The above structural design ensures strict coaxiality between the initial positioning center of the magnet block and the installation center of the rotor core.

[0012] Furthermore, the lower guide plate is provided with an upper guide plate, and the upper guide plate is provided with an upper slot, and the upper slot is the same size as the lower slot.

[0013] Through the above structural design, the upper guide plate and its upper slot are added, which work together with the lower slot of the lower guide plate to form a pair of guide channels of the same size.

[0014] Furthermore, the lower guide plate is provided with a lower groove, and the upper guide plate is provided with an upper groove, and the upper groove and the lower groove cooperate to guide the linear movement of the pusher.

[0015] Through the above structural design, the upper and lower grooves work together to form a linear track that precisely defines the movement path of the pusher.

[0016] Furthermore, the rotating disk is integrally provided with symmetrical extension arms, which are used to drive the rotating disk to rotate.

[0017] Through the above structural design, the symmetrically arranged extension arms provide a stable and balanced force application point for driving the rotary disk to rotate.

[0018] Furthermore, a movable groove is provided between the base and the lower guide plate, and the movable groove is used to limit the range of movement of the extension arm.

[0019] Through the above structural design, the movable groove precisely limits the movement range of the extension arm and defines the maximum and minimum rotation angles of the rotary disk, thereby accurately controlling the final stroke and starting position of the pusher.

[0020] Furthermore, the end of the extension arm is provided with a cylinder for pushing the extension arm to move, and the cylinder is fixedly connected to the base plate.

[0021] Through the above structural design, a cylinder is used as the drive source, and the entire mechanism is driven by pushing the extension arm, thus realizing the automation of the installation process.

[0022] Furthermore, the pusher includes a hollow sleeve that is rotatably connected to the guide rod, and an extension head is slidably disposed inside the hollow sleeve.

[0023] Through the above structural design, adjusting the position of the extension head will control the total length of the pusher, thus making it easy to adapt to rotor cores of various specifications or magnet blocks of different thicknesses.

[0024] Furthermore, the hollow sleeve is provided with a slot, and a limit rod is slidably arranged in the slot. The limit rod is fixedly connected to the extension head. Both ends of the limit rod are provided with movable plates, and screws are threaded on the movable plates.

[0025] With the above structural design, the extension head can be moved easily by the limiting rod. After the extension head is moved to the target position, the position of the limiting rod can be secured by screws, thereby fixing the extension head.

[0026] Compared with the prior art, the beneficial effects of this utility model are: the tooling fixture for synchronous installation of magnets achieves high-precision and completely synchronous installation of multiple magnets in one go through pre-positioning, synchronous driving and rigid guiding mechanisms, thereby improving assembly efficiency and assembly accuracy. The specific details are as follows:

[0027] When in use, the tooling fixture for synchronous installation of magnets uses a cylinder to push the symmetrical extension arms on the rotating disk, causing the rotating disk to rotate smoothly. The guide groove on the rotating disk drives the guide rod to move radially. The pushers, which are embedded in the lower groove of the lower guide disk and the upper groove of the upper guide disk, are constrained by the rigid linear track formed by the upper and lower slots, forcing the circumferential motion of the rotating disk into linear displacement without offset. All pushers move synchronously, overcoming magnetic interference, and push multiple magnets into the rotor core magnet slots simultaneously, equidistantly, and linearly with a completely consistent radial stroke. The extension arms are physically limited in the movable groove between the base and the lower guide disk, precisely controlling the stroke of the pushers and ensuring that all magnets are inserted to the same depth. This ultimately achieves high-precision, synchronous, automated installation without cumulative deviation. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] First embodiment:

[0038] like Figures 1-6 As shown, this utility model discloses a tooling fixture for synchronous installation of magnets, including a base plate 1 with an installation groove 10 for installing a rotor core. It also includes a clamping component 2 positioned above the base plate 1, which pushes magnet blocks into the magnet slots of the rotor core. The clamping component 2 includes a base 20 connected to the base plate 1, and a rotating disk 21 rotatably mounted above the base 20. The rotating disk 21 has a guide groove 210, and a guide rod 211 is positioned within the guide groove 210. A pusher 212 rotatably mounts the guide rod 211, and the pusher 212 pushes several magnet blocks to move synchronously. A lower guide disk 22 is positioned above the rotating disk 21, and a lower slot 221 is positioned on the lower guide disk 22, located outside the guide rod 211.

[0039] A mounting bracket 11 is fixedly installed above the base plate 1. The mounting bracket 11 is provided with a placement slot 12, and a magnet block is placed in the placement slot 12. The placement slot 12 provides a precise and consistent initial positioning reference for all magnet blocks to be installed. Before the installation operation begins, all magnet blocks are pre-placed accurately in their respective placement slots 12 to ensure that their starting positions relative to the rotor core and the subsequent driving mechanism are uniform and correct, thereby improving the initial accuracy and consistency of the installation and laying a reliable foundation for subsequent synchronous driving.

[0040] The mounting bracket 11 and the mounting slot 10 are concentric and coaxial. This feature ensures the strict coaxiality between the initial positioning center of the magnet block and the mounting center of the rotor core, so that the magnets are eventually evenly and symmetrically distributed on the rotor core. This effectively avoids the problem of uneven distribution of the magnetic poles caused by the initial positioning center not coinciding with the rotor center, and improves the accuracy of the final assembly.

[0041] The lower guide plate 22 is provided with an upper guide plate 23, which is provided with an upper slot 231. The upper slot 231 is the same size as the lower slot 221. The addition of the upper guide plate 23 and its upper slot 231, together with the lower slot 221 of the lower guide plate 22, forms a pair of guide channels of the same size, which enhances the constraint and guiding ability of the pusher 212 and the pushing magnet. The upper and lower clamping guide can more effectively prevent the pusher 121 from swaying, shaking or tilting during the pushing process. In particular, when overcoming the magnetic interference that may exist between magnets or between magnets and the groove wall, it can provide a stable motion trajectory, improve the straightness, stability and anti-interference ability of the magnet insertion process, thereby improving the installation accuracy and reliability.

[0042] The lower guide plate 22 is provided with a lower groove 220, and the upper guide plate 23 is provided with an upper groove 230. The upper groove 230 and the lower groove 220 cooperate to guide the linear movement of the pusher 212. The upper groove 220 and the lower groove 230 cooperate to form a linear track that precisely defines the movement path of the pusher 212, forcing the pusher 212 to move only along the preset, straight radial path. This completely eliminates the rotational freedom or radial offset that may occur during the pusher 212's pushing process, ensuring that the movement trajectories of all pusher 212 rods are strictly parallel and point towards the rotor center. This is the core guarantee for achieving absolute synchronization and deviation-free linear insertion of multiple magnets, thereby achieving high-precision synchronous installation.

[0043] The rotating disk 21 is integrally provided with symmetrical extension arms 213, which are used to drive the rotating disk 21 to rotate. The symmetrically arranged extension arms 213 provide a stable and balanced force point for driving the rotating disk 21 to rotate. The smooth rotational motion is the basis for the guide groove 210 to accurately convert the circular motion into the synchronous radial linear motion of all guide rods 211, ultimately ensuring the coordination and synchronicity of all magnet pushing actions.

[0044] A movable groove 200 is provided between the base 20 and the lower guide plate 22. The movable groove 200 is used to limit the movement range of the extension arm 213. The movable groove 200 provides precise physical limitation on the movement range of the extension arm 213, and limits the maximum and minimum rotation angle of the rotating plate 21. This precisely controls the final stroke and starting position of the pusher 212, ensuring that all magnets can be pushed to the exact same predetermined position in each installation operation. This achieves precise consistency in installation depth and avoids problems such as magnets being inserted too deeply, too shallowly, or in inconsistent positions due to inaccurate stroke control, thereby improving installation accuracy and product consistency.

[0045] The end of the extension arm 213 is equipped with a cylinder 13 for pushing the extension arm 213 to move. The cylinder 13 is fixedly connected to the base plate 1. Using the cylinder 13 as the drive source, the entire mechanism is driven by pushing the extension arm 213, which realizes the automation of the installation process. The cylinder 13 can provide a stable, controllable and sufficiently large driving force to ensure that even in the case of strong magnetic interference between magnets, synchronous pushing action can be reliably completed. The automated drive not only improves the installation efficiency, but also eliminates the unstable factors that may be caused by manual operation, further ensuring the speed, consistency and reliability of the action.

[0046] Second embodiment:

[0047] like Figure 7As shown, the pusher 212 includes a hollow sleeve 2120 rotatably connected to the guide rod 211, and an extension head 2121 is slidably disposed within the hollow sleeve 2120. A slot 2122 is provided on the hollow sleeve 2120, and a limit rod 2123 is slidably disposed within the slot 2122. The limit rod 2123 is fixedly connected to the extension head 2121. Moving plates 2124 are provided at both ends of the limit rod 2123, and screws 2125 are threaded onto the moving plates 2124. Through the sliding fit structure between the hollow sleeve 2120 and the extension head 2121, combined with the guiding of the limit rod 2123 within the slot 2122... The screw 2125 of the tension and moving plate 2124 has a fine-tuning function, which realizes the adaptive adjustment of the length of the pusher 212 and precise stroke control. The extension head 2121 can retract and slide relative to the hollow sleeve 2120, effectively buffering the installation impact and compensating for the depth tolerance of the magnet slot. At the same time, by turning the screw 2125 to adjust the position of the moving plate 2124, the maximum extension of the extension head 2121 can be precisely set, ensuring that all magnet blocks can fit tightly against the bottom of the slot and be evenly stressed during synchronous pushing. This completely eliminates the problems of magnet misalignment, tilting or local overload caused by part size deviation or uneven assembly resistance, and improves installation accuracy and product reliability.

[0048] Working principle: When using the tooling fixture for synchronous installation of magnets, the rotor core is first fixed in the mounting groove 10 of the base plate 1. All magnet blocks are precisely pre-positioned in the mounting bracket 11 placement groove 12, which is concentric and coaxial with the mounting groove 10, to ensure accurate initial positioning. At the same time, the position of the extension head 2121 is adjusted according to the specifications of the rotor core and magnet parts. After adjustment, the cylinder 13 is started. The cylinder 13 pushes the symmetrical extension arm 213 on the rotating disk 21, causing the rotating disk 21 to rotate smoothly. The guide groove 210 on the rotating disk 21 drives the guide rod 211 to move radially, while the groove 211 embedded in the lower guide disk 22... The pushers 212 in the grooves 230 of the upper guide plate 20 and the upper guide plate 23, under the constraint of the rigid linear track formed by the upper and lower slots, force the circular motion of the rotating plate 21 into a linear displacement without offset. All pushers 212 move synchronously, overcome magnetic interference, and push multiple magnets into the rotor core magnet slots simultaneously, equidistantly, and linearly with a completely consistent radial stroke. The extension arm 213 is physically limited in the movable groove 200 between the base 20 and the lower guide plate 22, precisely controlling the stroke of the pushers to ensure that all magnets are inserted to the same depth, ultimately achieving high-precision, synchronous, automated installation of the magnets without cumulative deviation.

[0049] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
