Description

Technical Field

[0001] This utility model relates to the field of motor rotor assembly technology, specifically to a motor rotor assembly pressing device. Background Technology

[0002] In the assembly of motor rotors, the iron core and the shaft of the motor rotor need to be pressed together to achieve the connection between the iron core and the shaft. A pressing device is required to press them together during assembly.

[0003] A search revealed that the Chinese patent with publication number CN216959607U discloses a motor rotor assembly and pressing device. Its key technical point is that it solves the problem that the existing pressing devices mostly rely on manual operation for feeding the shaft and iron core, resulting in low work efficiency and poor fixing effect on the iron core, which is not conducive to the precise pressing of the shaft and iron core, leading to poor overall work efficiency in the assembly and pressing of the two.

[0004] However, in the above-mentioned solutions and existing technologies, it has been found that when assembling and pressing the iron core and the shaft, a mold is required to hold the iron core. However, in the above-mentioned solutions and existing technologies, the mold cannot be changed, which makes it unusable when clamping iron cores of different sizes and models, requiring mold replacement and resulting in low applicability. In order to solve the problem of the existing technology where the clamping size of the mold cannot be changed and it cannot clamp iron cores of different sizes and models, resulting in low applicability, this application proposes to set an adjustable centering clamping component, thereby changing the clamping range of the mold to achieve the effect of clamping iron cores of different sizes and models, improving the applicability of the mold. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has the shortcomings and defects of being unable to clamp and press iron cores of different sizes and models, resulting in low applicability.

[0006] This utility model discloses a motor rotor assembly and pressing device, including a mold. A bevel gear 1 is rotatably connected to the inner wall of the mold. A bevel gear ring meshes with the outer surface of the bevel gear 1. A bevel gear 2 arranged at equal intervals meshes with the outer surface of the bevel gear ring. A threaded rod is threadedly connected to the inner wall of each bevel gear 2. A centering component is fixedly connected to the end of each threaded rod that is close to each other. A guide rod is slidably connected to the inner wall of each threaded rod. A limit frame is fixedly connected to the end of each guide rod that is far from each other. The outer surface of each limit frame is fixedly connected to the outer surface of the mold.

[0007] Furthermore, a limiting ring is fixedly connected to the inner bottom wall of the mold, and the outer surface of the limiting ring is rotatably connected to the inner wall of the bevel gear ring.

[0008] Furthermore, a mounting frame is fixedly connected to the bottom surface of the mold, a mounting bracket is fixedly connected to the bottom surface of the mounting frame, and a mounting plate is fixedly installed on the left side of the mounting bracket.

[0009] Furthermore, a mounting block is fixedly connected to the left side of the mounting bracket, and a sliding groove is provided on the left side of the mounting block.

[0010] Furthermore, the inner wall of the sliding groove is slidably connected to two sliding blocks, and each sliding block has a clamping component fixedly installed on its outer surface.

[0011] Furthermore, the inner wall of the mounting block is rotatably connected to a bidirectional screw, and the inner wall of each sliding block is threadedly connected to the outer surface of the bidirectional screw.

[0012] Furthermore, a telescopic rod is fixedly installed on the inner wall of the mounting plate, and a clamping block is fixedly connected to the output end of the telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as bevel gear one, bevel gear ring, bevel gear two, threaded rod, centering component, and guide rod, places the iron core inside the mold. At this time, rotating bevel gear one causes the bevel gear ring to rotate, which in turn drives the corresponding bevel gear two to rotate. Bevel gear two connects to the corresponding threaded rod. By setting up a limit frame and guide rod, the threaded rod is limited to prevent it from rotating. Under the rotation of bevel gear two, multiple threaded rods can move relative to each other, thereby enabling the threaded rods to drive the corresponding centering component to move relative to each other. This facilitates the centering and clamping of iron cores of different sizes and models, improving the applicability of the device.

[0015] 2. This utility model includes components such as an installation block, a sliding block, a clamping assembly, a bidirectional screw, a telescopic rod, and a pressing block. The installation block is installed on the left side of the mounting bracket. A sliding groove is provided, and the sliding block is installed inside the sliding groove. When the iron core is placed inside the mold, the two sliding blocks move relative to each other by rotating the bidirectional screw, which in turn drives the two clamping assemblies to clamp the iron core. This allows for clamping of iron cores of different sizes and models. In conjunction with the centering assembly inside the mold, the stability of the iron core when pressed against the rotating shaft is ensured. The telescopic rod and pressing block facilitate pressing the rotating shaft against the inner wall of the iron core, achieving a pressing and closing effect. Attached Figure Description

When the bevel tooth ring 3 rotates, the synchronous rotation effect of the four bevel gears 4 can be achieved.

[0024] like Figure 4As shown, each bevel gear 4 has a threaded rod 5 threadedly connected to its inner wall. The threaded rod 5 is installed on the inner wall of the bevel gear 4 and is set as a threaded connection. When the bevel gear 4 rotates, the threaded rod 5 moves through the threaded connection with the threaded rod 5. A centering component 6 is fixedly connected to the end of each threaded rod 5 that is close to each other. The centering component 6 is installed at the end of the threaded rod 5 that is close to each other.

[0025] In this embodiment, a guide rod 8 is slidably connected to the inner wall of each threaded rod 5. The guide rod 8 is installed on the inner wall of the threaded rod 5 and is set as a sliding connection.

The outer surface of the limiting ring 9 is rotatably connected to the inner wall of the bevel tooth ring 3. The limiting ring 9 and the bevel tooth ring 3 are connected and set as a rotatable connection to achieve the limiting effect of the bevel tooth ring 3.

[0027] In a preferred embodiment, a mounting bracket 10 is fixedly connected to the bottom surface of the mold 1, and the mounting bracket 10 is fixed to the bottom surface of the mold 1 to provide support for the mold 1.

A mounting plate 17 is fixedly installed on the left side of the mounting support 11, and the mounting plate 17 is fixed to the left side of the mounting support 11 to provide support for the mounting plate 17.

[0028] In this embodiment, a mounting block 12 is fixedly connected to the left side of the mounting bracket 11. The mounting block 12 is fixed to the left side of the mounting bracket 11 to achieve positioning of the mounting block 12. A sliding groove 13 is provided on the left side of the mounting block 12. The sliding groove 13 is provided on the left side of the mounting block 12 to achieve positioning of the sliding groove 13.

[0029] like Figure 3As shown, two sliding blocks 14 are slidably connected to the inner wall of the sliding groove 13. The sliding blocks 14 are installed on the inner wall of the sliding groove 13 and are set as a sliding connection. The contour of the sliding groove 13 can achieve the limiting effect of the sliding blocks 14. A clamping component 15 is fixedly installed on the outer surface of each sliding block 14. The clamping component 15 is installed on the outer surface of the sliding block 14 and is set as a fixed component. When the sliding blocks 14 move relative to each other, the relative movement effect of the sliding blocks 14 can be achieved by the clamping component 15.

[0030] In a preferred embodiment, a bidirectional screw 16 is rotatably connected to the inner wall of the mounting block 12. The bidirectional screw 16 is mounted on the inner wall of the mounting block 12 and configured as a rotatable connection to achieve a limiting effect on the bidirectional screw 16. The inner wall of each sliding block 14 is threadedly connected to the outer surface of the bidirectional screw 16. By connecting the sliding block 14 to the bidirectional screw 16, the relative movement of the sliding block 14 can be achieved by rotating the bidirectional screw 16, thereby achieving the relative movement of the clamping assembly 15, which facilitates clamping the iron core and ensures stability during pressing.

The telescopic rod 18 is hydraulically driven, and a pressing block 19 is fixedly connected to the output end of the telescopic rod 18. The pressing block 19 is installed on the output end of the telescopic rod 18. When the telescopic rod 18 extends, the pressing block 19 can be lowered; conversely, when it extends, the pressing block 19 can be raised, which facilitates pressing the rotating shaft against the inner wall of the iron core.

[0032] The implementation principle is as follows: The iron core is placed inside the mold 1. The bevel gear 2 is rotated to make the bevel ring 3 rotate. The bevel ring 3 drives the corresponding bevel gear 4 to rotate. The bevel gear 4 is connected to the corresponding threaded rod 5. The threaded rod 5 is limited by the setting of the limit frame 7 and the guide rod 8. Under the rotation of the bevel gear 4, multiple threaded rods 5 move relative to each other, thereby achieving the effect of relative movement of the centering component 6. It can center and clamp iron cores of different sizes and models. At this time, the bidirectional screw 16 is rotated to achieve the relative movement of the two sliding blocks 14, thereby driving the two clamping components 15 to clamp the iron core. It can clamp iron cores of different sizes and models. With the centering components inside the mold 1, the stability of the iron core and the rotating shaft can be ensured when they are pressed together. The telescopic rod 18 and the pressing block 19 are set to make it easy to press the rotating shaft against the inner wall of the iron core to achieve the pressing and closing effect.
