Description

Technical Field

[0001] This invention relates to the field of motor stator technology, specifically to a dust removal fixture for motor stators that eliminates dead angles. Background Technology

[0002] The stator is an important component of motors such as generators and starters. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current. During the assembly process, the stator will accumulate dust on its surface due to prolonged outdoor exposure.

[0003] However, existing motor stator dust removal devices have some problems in use. The existing dust removal effect is insufficient. During the dust removal process, there may be blind spots, resulting in incomplete dust cleaning. During the dust removal process, dust will float in the air, which may affect the working environment of the operators. At the same time, it is not easy to adapt to the dust removal of motor stators of different sizes, which will reduce the dust removal effect of the device. Moreover, if there are small stones or debris in the motor stator, simple brush cleaning cannot remove the small stones or debris from the motor stator. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, the purpose of this invention is to provide a dust removal fixture for motor stators that eliminates blind spots, facilitating dust removal from the surface of motor stators and achieving a dust removal effect with minimal blind spots. It can adapt to motor stators of different sizes, making it easy to remove small stones or debris from the motor stators, and also provides a certain degree of dust prevention.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention, through the cooperation of structures such as the connecting arc plate, horizontal plate, blower, and transparent frame, allows the motor stator to be placed inside the device. First, the blower is activated, and it blows air from bottom to top to remove dust from the surface of the motor stator. After the dust removal is completed, the elastic support plate is placed inside the connecting arc plate. The connecting U-shaped plate can limit the elastic support plate. At this time, the operator rotates the horizontal plate, which drives the motor stator to rotate. Small stones or debris in the motor stator will gradually be thrown out from inside the motor stator during rotation, thus saving the operator from having to visually observe and remove them.

[0014] By coordinating the components such as the moving plate, brush plate, elastic rope, and circular frame, the system can first adjust the moving plate, which then moves the adjacent transparent frame to place the motor stator inside the circular frame. This allows the blower to clean the surface of the motor stator by blowing air. The operator can then pull the elastic rope, which moves the brush plate closer to the motor stator. The front elastic rope pulls the brush plate forward, while the rear elastic rope pulls it backward, ensuring cleaning efficiency. Simultaneously, the motor drives a cam to rotate 180 degrees, repeatedly moving the brush plate closer to the motor stator for dust removal. Furthermore, the position of the blower or the device itself can be changed, allowing the device to clean dust from both bottom to top and top to bottom. Attached Figure Description

The side of the connecting arc-shaped plates 5 away from the horizontal plate 1 has a first arc-shaped groove, and sliding grooves are formed on both the left and right sides of the first arc-shaped groove. The groove and the inner cavity of the arc groove are provided with elastic support plates 6. The left and right sides of the elastic support plates 6 are fixedly connected to the top of the sliders 17. The sliders 17 are movably connected to the inner cavity of the adjacent groove. The outer edge of the connecting arc plate 5 is fitted with a connecting U-shaped plate 15 near the bottom. The side of the connecting arc plate 5 away from the center of the horizontal plate 1 is fixedly connected to three connecting springs 16 near the bottom. The ends of the three adjacent connecting springs 16 away from the connecting arc plate 5 are fixedly connected to the inner cavity side wall of the adjacent connecting U-shaped plate 15. The top and bottom of the horizontal plate 1 are provided with adjustment mechanisms.

[0032] T-shaped rods 20 are fixedly connected to the center of both the front and rear sides of the horizontal plate 1. Blind holes are provided at the top and bottom of each T-shaped rod 20. Vertical rods 19 are provided within the lower blind holes. Limiting L-shaped rods 18 are fixedly connected to the bottom of each vertical rod 19.

Several adjusting grooves are provided at the bottom of the circular frame 11. First threaded holes are provided on both the front and rear sides of the T-shaped rods 20 near the top and bottom. Second threaded holes are provided within the cavities of the vertical rods 19. Threaded rods 21 are threadedly connected to the cavities of the first threaded holes.

Limiting U-shaped plates 22 are fixedly connected to the ends of the adjusting rods 40 away from the U-shaped blocks 39. The center of the movable plate 26... Located within the inner cavity of the adjacent limiting U-shaped plate 22, a blower 8 is provided at the bottom of the circular frame 11. Connecting L-shaped rods 9 are fixedly connected to the front and rear sides of the blower 8 near the top. A circular ring 10 is fixedly connected to the end of the connecting L-shaped rod 9 away from the blower 8. The circular ring 10 is fitted onto the outer edge of the adjacent limiting L-shaped rod 18. A transparent frame 3 is provided at the top of the two upper movable plates 4. Two slots are opened on the corresponding side of the two transparent frames 3. Magnets 42 are fixedly connected to the inner cavity of the slots. The two adjacent magnets 42 are magnetically attracted to each other. A fixing plate 12 is fixedly connected to the bottom side of the transparent frame 3 away from the center of the horizontal plate 1. A third threaded hole is opened on the side of the movable plate 4 away from the horizontal plate 1. A fourth threaded hole is opened in the inner cavity of the fixing plate 12. A bolt 13 is threadedly connected to the inner cavity of the fourth threaded hole. The bottom end of the bolt 13 is threadedly connected to the inner cavity of the adjacent third threaded hole.

[0033] After placing the motor stator inside the device, start the blower 8. The blower 8 will blow air from bottom to top to remove dust from the surface of the motor stator. After the dust removal of the motor stator is completed, place the elastic support plate 6 inside the connecting arc plate 5. The connecting U-shaped plate 15 can limit the elastic support plate 6. At this time, the operator can rotate the horizontal plate 1, which will drive the motor stator to rotate. Small stones or debris in the motor stator will be gradually thrown out from the inside of the motor stator during rotation, thus saving the operator from having to observe and remove them by eye.

[0034] Further, please refer to Figure 1-2 , Figure 8-12 , Figure 14 The adjustment mechanism includes four movable plates 4, which are symmetrically arranged in pairs, one above the other. A circular groove is formed at the center of the top of the horizontal plate 1. Through grooves are formed on the front and rear sides of the top of the horizontal plate 1 near the left and right sides. Support columns 43 penetrate the inner cavities of these through grooves. The top and bottom ends of the support columns 43 are fixedly connected to one side of the adjacent movable plate 4. A second arc-shaped groove is formed on the side of each movable plate 4 near the center of the horizontal plate 1. A through hole is formed on the side of each movable plate 4 away from the center of the horizontal plate 1. The through hole and the second arc-shaped groove are interconnected. A movable rod 31 penetrates the inner cavity of each second through hole. A brush plate 30 is provided at the end of each movable rod 31 near the center of the horizontal plate 1. An arc-shaped T-groove is formed on the side of each brush plate 30 near the movable plate 4. A T-shaped block 41 is movably connected to the inner cavity of each arc-shaped T-groove. The T-shaped block 41 is located away from the brush plate 30. Each side is fixedly connected to one end of the adjacent movable rod 31. The front and rear sides of the movable plate 4 are provided with connection holes on the side near the center of the horizontal plate 1. The front and rear sides of the brush plate 30 are fixedly connected with elastic ropes 28. The front and rear sides of the movable plate 4 are fixedly connected with two fixed tubes 29. The end of the elastic rope 28 away from the brush plate 30 passes through the two adjacent fixed tubes 29 and is fixedly connected with an adjustment plate 27. The outer edges of the two adjacent elastic ropes 28 are fitted with movable plates 26. The side of the adjacent upper and lower movable plates 4 away from the center of the horizontal plate 1 is fixedly connected with two U-shaped rods 23. The side of the U-shaped rod 23 is fixedly connected with a limiting arc plate 24. The side of the limiting arc plate 24 near the horizontal plate 1 is fixedly connected with a limiting spring 25. The end of the limiting spring 25 away from the limiting arc plate 24 is fixedly connected to the side of the horizontal plate 1.

[0035] The end of the movable rod 31 away from the brush plate 30 is fixedly connected to a connecting plate 35. The side of the connecting plate 35 away from the movable plate 4 is fixedly connected to two fixing springs 34. The ends of the two adjacent fixing springs 34 away from the connecting plate 35 are jointly fixedly connected to a vertical plate 32. One side of the vertical plate 32 is fixedly connected to the top and bottom of the horizontal plate 1. The outer edges of the adjacent vertical plates 32 and the connecting plate 35 are jointly fixedly connected to two elastic plates 33. The top and bottom of the horizontal plate 1 are fixedly connected to motors 36 near the left and right sides. The power output shaft of the motor 36 is fixedly connected to a transmission rod 37. The end of the transmission rod 37 away from the motor 36 is fixedly connected to a cam 38. The cam 38 is located between the adjacent connecting plate 35 and the vertical plate 32.

[0036] First, adjust the moving plate 4. The moving plate 4 moves the adjacent transparent frame 3 to place the motor stator inside the circular frame 11, making it convenient for the blower 8 to blow dust off the surface of the motor stator. Then, the operator can pull the elastic rope 28. The elastic rope 28 moves the brush plate 30 closer to the motor stator. The front elastic rope 28 pulls the brush plate 30 to rotate forward, and the rear elastic rope 28 pulls the brush plate 30 to rotate backward, thus ensuring cleaning efficiency. At the same time, the motor 36 drives the cam 38 to rotate 180 degrees. The cam 38 can repeatedly move the brush plate 30 closer to the motor stator for dust removal. Moreover, the position of the blower 8 or the device itself can be changed, so that the device can blow dust from bottom to top or from top to bottom.

[0037] Working principle: When the device starts working, the operator first adjusts the moving plate 4 left and right. The moving plate 4 moves the support column 43, which in turn moves the U-shaped rod 23. The U-shaped rod 23 is stretched by the limiting arc plate 24 and the limiting spring 25. At the same time, the moving plate 4 moves the adjacent transparent frame 3 through the bolt 13 and the fixing plate 12, thus exposing the center of the horizontal plate 1. The operator can then pass the motor stator through the center of the horizontal plate 1, with the bottom of the motor stator contacting the inside of the circular frame 11 and the top of the motor stator passing through the inner cavity of the horizontal plate 1. Then, the moving plate 4 is released, and the moving plate 4 returns to its initial position due to the elasticity of the limiting spring 25. Position: The transparent frame 3 covers the motor stator, allowing the operator to see through it. The operator then activates the blower 8, which blows air from bottom to top through the circular frame 11 to the motor stator, dispersing any dust on its surface. The transparent frame 3 provides some dust protection. If further dust removal is needed, the operator can use two methods: one is external motor cleaning, and the other is manual cleaning. To further explain the first method: starting the motor 36 via an external power supply. Motor 36 is a servo motor. [The text then repeats the steps for setting motor 36.] The motor 36 rotates 180 degrees back and forth, driving the transmission rod 37 to rotate 180 degrees. The transmission rod 37 then drives the cam 38 to rotate 180 degrees. The cam 38 repeatedly drives the connecting plate 35 to move left and right. Each time the cam 38 rotates 180 degrees, it stretches the elastic plate 33. When the connecting plate 35 moves, it stretches the fixed spring 34. The elastic plate 33 restricts the movement of the connecting plate 35 and compresses the fixed spring 34. When the connecting plate 35 moves left and right, it drives the movable rod 31 to move. The movable rod 31 drives the brush plate 30 to move left and right through the T-block 41. As the brush plate 30 moves, it repeatedly approaches and contacts the motor stator, thus removing dust from the surface of the motor stator. Secondly, two operators stand on the front and back sides of the horizontal plate 1, each holding a limiting U-shaped plate 22. When the operator on the front rotates the right limiting U-shaped plate 22 forward, the limiting U-shaped plate 22 causes the adjusting rod 40 to rotate inside the U-shaped block 39. At this time, the operator on the back will not move the limiting U-shaped plate 22 on their left side, but will start rotating the limiting U-shaped plate 22 on their right side, while the operator on the front will not move the limiting U-shaped plate 22 on their left side.This process begins with repeated pulling: the front side is pulled while the back side remains stationary, and vice versa. During pulling, the limiting U-shaped plate 22, via the movable plate 26 and adjusting disc 27, stretches the elastic rope 28. The elastic rope 28 then rotates the adjacent brush plate 30 in the pulling direction. This operation allows the brush plate 30 to rotate back and forth on the motor stator surface, effectively removing dust. After dust removal, if small stones or debris remain in the motor stator, the operator first moves the elastic support plate 6, placing it inside the connecting arc plate 5. The elastic support plate 6 can be moved via the slider 17, and then the connecting U-shaped plate is moved left and right. 15. The connecting U-shaped plate 15 stretches the connecting spring 16, facilitating the placement of the elastic support plate 6 inside the connecting arc-shaped plate 5. Then, the connecting U-shaped plate 15 is released, limiting the elastic support plate 6. Before this, the elastic support plate 6 supports and balances the horizontal plate 1. After the elastic support plate 6 is retracted, the horizontal plate 1 can be easily rotated. The operator rotates the horizontal plate 1, which, through the moving plate 4, transparent frame 3, and circular frame 11, drives the motor stator to rotate. During rotation, some small stones or debris inside the motor stator will be expelled, saving the operator the trouble of visually inspecting and removing them. If it is necessary to blow air from top to bottom onto the motor stator, two methods can be used. One method is to change the vertical position of the transparent frame 3 and the blower 8. Rotate the lower threaded rod 21 to remove the vertical rod 19 from the blind hole below the T-shaped rod 20, thus removing the round frame 11 and the blower 8. Then, rotate the bolt 13 to remove it from the fixing plate 12, remove the transparent frame 3 from the top of the upper movable plate 4, place the transparent frame 3 at the bottom of the two lower movable plates 4, and limit the transparent frame 3 with the bolt 13 and the fixing plate 12. Then, rotate the position of the motor stator so that the top of the original motor stator is placed at the bottom of the inner cavity of the two transparent frames 3, and the bottom of the original motor stator is placed on top. Then, the hair dryer 8 and the circular frame 11 are placed on top of the upper movable plate 4. One end of the vertical rod 19 is placed in the blind hole at the top of the T-shaped rod 20 and limited by the threaded rod 21. The hair dryer 8 is then started, and it blows air from top to bottom. This process is achieved by the elastic support plate 6 supporting and balancing the horizontal plate 1. Secondly, the position of the motor stator itself is changed by adjusting the movable plate 4. The movable plate 4 moves the transparent frame 3, swapping the upper and lower positions of the motor stator inside the horizontal plate 1. Then, the hair dryer 8 is started, and it blows air from top to bottom. This process is achieved after the elastic support plate 6 is stored, and the hair dryer 8 rotates to the top as the horizontal plate 1 rotates.
