[0001] This utility model relates to the field of motor core technology, and in particular to an efficient and convenient assembly fixture for inserting motor magnets into stator cores. Background Technology

[0002] The stator core of a motor is a major component of the motor's magnetic circuit. It is typically made of laminated silicon steel sheets and is part of the motor's magnetic circuit. Inserting the motor magnets into the stator core is a crucial step in motor manufacturing. Traditional assembly methods often rely on manual operation, which is not only time-consuming and labor-intensive but also makes it difficult to guarantee assembly accuracy and consistency. Therefore, an efficient and convenient assembly fixture for inserting motor magnets into the stator core is needed.

[0003] The efficient and convenient motor magnet stator core assembly fixture has the advantages of high automation, accurate positioning, simple operation, strong adaptability and improved production efficiency. Traditional fixtures often adopt a fixed structure with fixed size and shape, which cannot adapt to magnet stators of different sizes. Therefore, the previous motor magnet stator core assembly fixtures could not achieve the effect of clamping magnet stators of different sizes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a highly efficient and convenient motor magnet stator core assembly fixture, which aims to improve the problem that previous motor magnet stator core assembly fixtures could not effectively clamp stators of different sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency and convenient assembly fixture for inserting motor magnets into stator cores includes a base. A protective shell is fixedly connected to the upper surface of the base. A limit ring is fixedly connected to the inner top wall of the protective shell. A hydraulic press is fixedly connected inside the base. A connecting block is fixedly connected to the output end of the hydraulic press. An annular frame is rotatably connected to the lower surface of the connecting block. The outer wall of the annular frame is rotatably connected to the inner wall of the limit ring and the outer wall of the base. A first fixed shaft is fixedly connected inside the annular frame. A limit block is rotatably connected to the outer wall of the first fixed shaft. A clamping arm is slidably connected inside the limit block. A second fixed shaft is fixedly connected to the outer wall of the base. The clamping arm is rotatably connected to the outer wall of the second fixed shaft. A support assembly is provided on the lower surface of the base to assist in fixing the base.

[0007] Preferably, the support assembly includes a support plate, the upper surface of which is fixedly connected to the lower surface of the base, and a support column is fixedly connected to the lower surface of the support plate.

[0008] Preferably, a bottom shell is slidably connected to the outer wall of the support column, and a first motor is fixedly connected inside the bottom shell, with a worm gear fixedly installed at the output end of the first motor.

[0009] Preferably, the toothed end of the worm is engaged with a worm wheel, and a connecting rod is fixedly connected inside the worm wheel.

[0010] Preferably, the outer wall of the connecting rod is rotatably connected to the inside of the bottom shell, and a U-shaped frame is fixedly connected to the outer wall of the connecting rod.

[0011] Preferably, a second motor is fixedly connected inside the U-shaped frame, and a first bevel gear is fixedly installed at the output end of the second motor.

[0013] Preferably, the interior of the second bevel gear is fixedly connected to the outer wall of the support column, and the outer wall of the support column is rotatably connected to the interior of the U-shaped frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the hydraulic press drives the annular frame to rotate between the base and the limiting ring through the connecting block. Under the limitation of the first fixed shaft, the annular frame drives the clamping arm to rotate on the second fixed shaft through the limiting block, thereby achieving the effect of clamping magnet stators of different sizes, thus eliminating the need for frequent clamping.

[0016] 2. In this utility model, the first motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. Then, the worm wheel drives the connecting rod to rotate, which in turn drives the support column to slide in the bottom shell through the U-shaped frame.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a high-efficiency and convenient motor magnet stator core assembly fixture, comprising a base 1, a protective shell 2 fixedly connected to the upper surface of the base 1, a limit ring 3 fixedly connected to the inner top wall of the protective shell 2, a hydraulic press 4 fixedly connected inside the base 1, a connecting block 5 fixedly connected to the output end of the hydraulic press 4, an annular frame 6 rotatably connected to the lower surface of the connecting block 5, the outer wall of the annular frame 6 rotatably connected to the inner wall of the limit ring 3, the outer wall of the annular frame 6 rotatably connected to the outer wall of the base 1, a first fixed shaft 7 fixedly connected inside the annular frame 6, a limit block 8 rotatably connected to the outer wall of the first fixed shaft 7, a clamping arm 9 slidably connected inside the limit block 8, a second fixed shaft 10 fixedly connected to the outer wall of the base 1, the clamping arm 9 rotatably connected to the outer wall of the second fixed shaft 10, and a support assembly provided on the lower surface of the base 1 for assisting in fixing the base 1.

[0024] Specifically, the hydraulic press 4 drives the connecting block 5 to rotate on the outer wall of the annular frame 6, and the connecting block 5 pushes the annular frame 6 to rotate between the base 1 and the limiting ring 3. The limiting ring 3 limits the annular frame 6. The annular frame 6 drives the clamping arm 9 to rotate on the second fixed shaft 10 through the limiting block 8. The limiting block 8 and the second fixed shaft 10 together limit the clamping arm 9, thereby achieving the effect of clamping and fixing the magnet stator.

[0025] Reference Figure 1 and Figure 3 The support assembly includes a support plate 11, the upper surface of which is fixedly connected to the lower surface of the base 1, and a support column 12 is fixedly connected to the lower surface of the support plate 11.

[0026] Specifically, the support plate 11 serves to support and fix the base 1, and the support column 12 serves to support and fix the support plate 11.

[0027] Reference Figure 1 and Figure 3 A base shell 13 is slidably connected to the outer wall of the support column 12. A first motor 14 is fixedly connected inside the base shell 13. A worm gear 15 is fixedly installed at the output end of the first motor 14. A worm wheel 16 is meshed with the tooth end of the worm gear 15. A connecting rod 17 is fixedly connected inside the worm wheel 16. The outer wall of the connecting rod 17 is rotatably connected to the inside of the base shell 13. A U-shaped frame 18 is fixedly connected to the outer wall of the connecting rod 17. A second motor 19 is fixedly connected inside the U-shaped frame 18. A first bevel gear 20 is fixedly installed at the output end of the second motor 19. A second bevel gear 21 is meshed with the tooth end of the first bevel gear 20. The second bevel gear 21 is fixedly connected to the outer wall of the support column 12. The outer wall of the support column 12 is rotatably connected to the inside of the U-shaped frame 18.

[0028] Specifically, the first motor 14 drives the worm gear 15 to rotate, which in turn drives the worm wheel 16 to rotate the connecting rod 17. The connecting rod 17, through the U-shaped frame 18, drives the support column 12 to slide within the base shell 13. The second motor 19 drives the first bevel gear 20 to rotate, which in turn drives the support column 12 to rotate within the U-shaped frame 18. This allows the angle of the base 1 to be adjusted via the support plate 11.

[0029] Working principle: When this fixture is needed, first place the magnet stator to be assembled in the base 1, then start the hydraulic press 4. The hydraulic press 4 drives the connecting block 5 to rotate on the outer wall of the annular frame 6, and then the connecting block 5 pushes the annular frame 6 to rotate between the base 1 and the limiting ring 3. The annular frame 6 drives the clamping arm 9 to rotate on the second fixed shaft 10 through the limiting block 8, thereby clamping and fixing the magnet stator. The first motor 14 drives the worm gear 15 to rotate, and the worm gear 15 drives the worm wheel 16 to drive the connecting rod 17 to rotate. The connecting rod 17 drives the support column 12 on the base through the U-shaped frame 18. The first bevel gear 20 rotates through the second motor 19, which in turn drives the support column 12 to rotate within the U-shaped frame 18. The angle of the base 1 can then be adjusted via the support plate 11. This fixture not only achieves the effect of clamping stators of different sizes of magnets without the need for frequent fixture changes, thus reducing production preparation time and costs, but also allows for on-demand angle adjustment of the clamped stators. This ensures that the magnets are accurately positioned within the stator core and that each stator exhibits consistent performance after assembly, thereby improving the overall performance of the motor.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
