Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor assembly technology, and in particular to a magnet assembly fixture for permanent magnet motors. Background Technology

[0002] Currently, permanent magnet motors use permanent magnets to generate the motor's magnetic field, eliminating the need for excitation coils and excitation current. They offer advantages such as simple structure and high efficiency, making them excellent energy-saving motors. With the advent of high-performance permanent magnet materials and the rapid development of control technology, the applications of permanent magnet motors will become even more widespread.

[0003] Currently, the magnet assembly fixtures for permanent magnet motors are fixed at the workstation, and each fixture is only suitable for one size of rotor core. When a rotor core of the same model is replaced with one that is slightly larger or smaller, the current assembly fixture also needs to be replaced. It is not possible to use the current assembly fixture to assist in the installation of magnets on the same model of rotor core. Replacing the fixture is cumbersome and affects the processing efficiency of permanent magnet motors. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a magnet assembly fixture for permanent magnet motors.

[0005] This utility model is achieved using the following technical solution: a magnet assembly fixture for a permanent magnet motor, comprising a base, a rotor core on the top of the base, a plurality of magnet slots for installing magnets on the rotor core, an assembly assembly that can be quickly replaced to accommodate magnets for rotor cores of different sizes on the top of the base, an adjustment assembly that can adjust the position of the magnets installed on the assembly assembly on one side, and a support assembly that supports the rotor core and can be quickly replaced on the bottom of the rotor core. The assembly assembly includes an assembly plate on the top of the base, and a limiting port arranged in a circular array on the assembly plate. A limiting block is slidably installed on each limiting port, and a limiting plate is fixedly installed on one side of each limiting block.

[0006] With the above technical solution, when installing magnets on rotor cores of the same model but different sizes, it is only necessary to move the assembly component to one side of the rotor core, and then use the adjustment component to adjust the position of the magnet insertion port of the assembly component so that the magnet insertion port can be aligned with the magnet slot of the rotor core. This makes it convenient for workers to directly insert the magnet into the inside of the rotor core when inserting the magnet, avoiding friction between the magnet and the surface of the rotor core, which would affect the installation quality.

[0007] As a further improvement to the above solution, each of the limiting plates is provided with a magnet insertion port.

[0008] By aligning the magnet insertion port with the magnet slot, the magnet can be directly inserted into the magnet slot, thus avoiding friction between the magnet and the rotor core.

[0009] As a further improvement to the above solution, a push plate is rotatably mounted on one side of each of the limiting blocks, and a pressing plate is provided on one side of the assembly plate. One end of each push plate is rotatably engaged with the pressing plate.

[0010] With the above technical solution, the extrusion plate moves closer to the assembly plate, which can squeeze the push plate to make the push plate move, thereby allowing the push plate to push the limit block to move, and finally complete the position adjustment of the limit plate.

[0011] As a further improvement to the above solution, the adjustment component includes a threaded post disposed on one side of the extrusion plate. One end of the threaded post is threaded through the extrusion plate and a rubber plate is fixedly installed thereon. The rubber plate is rotatably installed with the assembly plate, and a rotating block is fixedly installed at the other end of the threaded post.

[0012] With the above technical solution, the rotation of the threaded column will cause the extrusion plate to move, and the rubber plate will fit with the assembly plate, thus preventing the threaded column from rotating on its own and causing the position of the extrusion plate to change.

[0013] As a further improvement to the above solution, a sliding groove is provided on the top of the base, a sliding block is slidably installed inside the sliding groove, a limiting half-ring is fixedly installed on the top of the sliding block, a fixing groove is provided on the inner ring surface of the limiting half-ring, and the assembly plate is inserted into the inside of the fixing groove.

[0014] Through the above technical solution, the assembly plate can be removed from the limiting half ring, so that different assembly tools can be replaced according to different models of rotor cores. In addition, the sliding block can bring the assembly plate close to the rotor core, making it convenient to install the magnet after the position of the limiting plate is adjusted.

[0015] As a further improvement to the above solution, the support assembly includes a rubber ring fixedly installed on the top of the base, a support seat is inserted inside the rubber ring, and a limiting groove adapted to the rotor core is opened on the top of the support seat.

[0016] With the above technical solution, when the size of the rotor core changes, it is only necessary to remove the support from the rubber ring and insert a suitable support to support the current rotor core.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting up an assembly component, an adjustment component, and a support component, allows for the installation of magnets on rotor cores of the same model but different sizes. Simply move the assembly component to one side of the rotor core, and then use the adjustment component to adjust the position of the magnet insertion port on the assembly component. This ensures the magnet insertion port aligns with the magnet slot of the rotor core, allowing workers to directly insert the magnet into the rotor core and preventing friction between the magnet and the rotor core surface, which could affect the installation quality.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 This embodiment of a permanent magnet motor magnet assembly fixture includes a base 1, a rotor core 2 on the top of the base 1, a plurality of magnet slots for installing magnets on the rotor core 2, an assembly assembly that can be quickly replaced to accommodate magnets of different sizes on the rotor core 2 on the top of the base 1, an adjustment assembly that can adjust the position of the magnets installed on the assembly assembly on one side, and a support assembly that supports the rotor core 2 and can be quickly replaced on the bottom of the rotor core 2. The assembly assembly includes an assembly plate 301 on the top of the base 1, a limiting port 302 arranged in a ring array on the assembly plate 301, a limiting block 303 slidably installed on each limiting port 302, a limiting plate 304 fixedly installed on one side of each limiting block 303, and a magnet insertion port 6 on each limiting plate 304.

[0026] When installing magnets on rotor cores 2 of the same model but different sizes, simply move the assembly assembly to one side of the rotor core 2, and then use the adjustment assembly to adjust the position of the magnet insertion port of the assembly assembly so that the magnet insertion port can be aligned with the magnet slot of the rotor core 2. This makes it convenient for workers to directly insert the magnet into the interior of the rotor core 2, avoiding friction between the magnet and the surface of the rotor core 2, which would affect the installation quality.

[0027] Aligning the magnet insertion port 6 with the magnet slot allows the magnet to be directly inserted into the magnet slot, preventing the magnet from rubbing against the rotor core 2.

[0028] Each limit block 303 has a push plate 7 rotatably mounted on one side, and an extrusion plate 8 is provided on one side of the assembly plate 301. One end of each push plate 7 is rotatably engaged with the extrusion plate 8. The adjustment assembly includes a threaded post 401 provided on one side of the extrusion plate 8. One end of the threaded post 401 is threaded through the extrusion plate 8 and a rubber plate 402 is fixedly mounted thereon. The rubber plate 402 is rotatably mounted with the assembly plate 301, and a rotating block is fixedly mounted on the other end of the threaded post 401.

[0029] The rotation of the threaded column 401 will cause the extrusion plate 8 to move. The extrusion plate 8 moves closer to the assembly plate 301, which can squeeze the push plate 7 and cause the push plate 7 to move. This push plate 7 pushes the limit block 303 to move, and finally completes the position adjustment of the limit plate 304.

[0030] The rubber plate 402 will fit against the assembly plate 301 to prevent the threaded column 401 from rotating on its own and causing the position of the extrusion plate 8 to change.

[0031] The top of the base 1 has a sliding groove, and a sliding block 9 is slidably installed inside the sliding groove. A limiting half ring 10 is fixedly installed on the top of the sliding block 9. A fixing groove is opened on the inner ring surface of the limiting half ring 10, and the assembly plate 301 is inserted into the inside of the fixing groove.

[0032] The assembly plate 301 can be removed from the limiting half ring 10 so that different assembly tools can be replaced according to different models of rotor core 2. The sliding block 9 can bring the assembly plate 301 close to the rotor core 2, so that the magnet can be installed after the position of the limiting plate 304 is adjusted.

[0033] The support assembly includes a rubber ring 501 fixedly installed on the top of the base 1. A support seat 502 is inserted into the inside of the rubber ring 501. The top of the support seat 502 is provided with a limiting groove that is adapted to the rotor core 2.

[0034] When the size of the rotor core 2 changes, simply remove the support seat 502 from the rubber ring 501 and insert a suitable support seat 502 to support the current rotor core 2.

[0035] The implementation principle of a permanent magnet motor magnet assembly fixture in this application embodiment is as follows: when assisting in the assembly of magnets for rotor cores 2 of the same model but different sizes, it is only necessary to pull the support seat 502 out from inside the rubber ring 501, and then insert the appropriate support seat 502 to support the current rotor core 2.

[0036] Next, move the sliding block 9 to bring the limiting half-ring 10, along with the assembly plate 301, closer to the rotor core 2. Then, rotate the threaded column 401 to move the extrusion plate 8. When the extrusion plate 8 moves toward the assembly plate 301, it will push multiple push plates 7. This will cause the multiple push plates 7 to move and push the adjacent limiting block 303. The limiting block 303 slides on the limiting port 302, which can adjust the position of the limiting plate 304, so that the magnet insertion port 6 of the limiting plate 304 is aligned with the magnet slot of the rotor core 2. Finally, the magnet can be directly inserted into the magnet insertion port 6 and then into the magnet slot. This can prevent the magnet from colliding with the rotor core 2 and causing scratches when the operator inserts the magnet.

[0037] When the rotor core 2 changes not only in size but also in model, the assembly plate 301 can be removed from the limiting half ring 10, a suitable assembly tooling can be selected, and the assembly plate 301 can be inserted into the fixing groove of the limiting half ring 10 to complete the quick replacement of the assembly tooling. This setting can improve the tooling replacement speed and increase the processing efficiency of the permanent magnet motor.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
