Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a motor rotor balance testing device. Background Technology

[0002] When the motor rotor rotates around its axis, centrifugal force is generated due to the uneven mass distribution relative to the axis. This unbalanced centrifugal force acts on the rotor bearings, causing vibration, affecting the normal operation of the motor, and shortening its service life.

[0003] To test the balance of a motor rotor, a rotor balance testing device is required. However, existing devices require removing the rotor after testing and then placing a new rotor on the support frame for testing, making rotor loading and unloading inconvenient. Therefore, to address these issues, a new motor rotor balance testing device is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a motor rotor balance detection device, including a support frame. A first motor is fixedly connected to the outer side of the support frame, a pulley is rotatably connected to the inner side of the support frame, and a belt is rotatably connected to the outer side of the pulley. One of the pulleys is fixedly connected to the output end of the first motor. A second motor is fixedly connected to the outer side of the support frame, and a first rotating wheel is fixedly connected to the output end of the second motor. A displacement sensor is fixedly connected to the outer side of the support frame. A movable component is slidably connected to the inner side of the support frame. A spring is fixedly connected to one end of the movable component, and one end of the spring is fixedly connected to the support frame. A second rotating wheel is rotatably connected to one end of the movable component. A hydraulic cylinder is fixedly connected to the outer side of the support frame, and a lifting frame is fixedly connected to the output end of the hydraulic cylinder. A belt is rotatably connected to the inner side of the lifting frame. A third rotating wheel is connected. This step involves setting up a displacement sensor, a movable component, a spring, and a second rotating wheel. The rotor is moved close to the lifting frame by the belt rotation. The lifting frame then raises the rotor's shaft, bringing it into contact with the third rotating wheel. The rotor then moves to be close to the first and second rotating wheels. The first rotating wheel drives the rotor's shaft to rotate, and the spring causes the movable component to press down, ensuring that the second rotating wheel remains close to the rotor's shaft. If the rotor experiences centrifugal force due to misalignment, this force will affect the second rotating wheel and be transmitted to the movable component. The displacement sensor monitors the movement of the movable component to ensure the rotor's balance is within acceptable limits. After detection, the rotor is lowered to the upper side of the belt to continue moving. This eliminates the need for additional rotor placement and removal, improving the ease of loading and unloading the device.

[0005] In one embodiment of this utility model, a socket is provided on the outside of the first motor, a movable plate is fixedly connected to the outside of the lifting frame, and a plug is fixedly connected to the outside of the movable plate. By setting the socket, movable plate, and plug, when the first motor is connected to the power supply, the socket can be set on the outside of the first motor, and the movable plate and plug can be set on the outside of the lifting frame. The plug is connected to the power supply through a wire, so that when the lifting frame drives a rotor to rise, it will drive the movable plate and plug to rise, causing the plug to separate from the socket, thereby cutting off the power to the first motor. This makes it difficult for the belt to drive the undetected rotor on the upper side of the belt to continue moving, thus reducing the likelihood of the undetected rotor continuing to move and improving the stability of the device's detection.

[0006] In one embodiment of this utility model, a first gear is fixedly connected to the outer side of one of the pulleys, and a second gear meshes with the outer side of the first gear. The second gear is rotatably connected to the support frame, and a partition plate is fixedly connected to the side of the second gear that is close to each other. This step, by setting the first gear, the second gear, and the partition plate, ensures that when the pulley rotates, it drives the first gear to rotate, which in turn drives the second gear to rotate, which in turn drives the partition plate to rotate. By placing the rotor at different positions inside the partition plate, the rotor can be evenly separated and moved to the upper side of the belt, thereby ensuring that the rotors are evenly distributed and not too scattered or too concentrated, thus improving the stability of the feeding device.

[0007] In one embodiment of this utility model, a third motor is fixedly connected to the outer side of the support frame, and a threaded screw is fixedly connected to the output end of the third motor. A clamping plate is threadedly connected to the outer side of the threaded screw, and a sliding rod is fixedly connected to the outer side of the clamping plate. The sliding rod and the support frame are slidably connected. This step, by setting up the third motor, the threaded screw, the clamping plate, and the sliding rod, ensures that when the rotor moves to the upper side of the belt, the third motor drives the threaded screw to rotate, and the threaded screw drives the clamping plate to move closer to each other. Thus, the rotor shaft contacts the clamping plate, and the clamping plate guides the rotor to the center, making its movement more stable and improving the stability of the device.

[0008] In one embodiment of this utility model, a limiting plate is fixedly connected to the outer side of the slide rod, and the limiting plate and the support frame are used in conjunction. By setting the limiting plate, when the clamping plate moves to the extreme position, the support frame is pressed against the limiting plate, thereby restricting the clamping plate. This prevents the clamping plate from getting too close to the belt and coming into contact with it, which would cause the belt to be squeezed and affect the conveying of the device, thus improving the stability of the device.

[0009] In one embodiment of this utility model, a limiting rod is fixedly connected to the outside of the lifting frame, and the limiting rod and the support frame are slidably connected. This step, by setting the limiting rod, allows the support frame to restrict the limiting rod when the lifting frame moves up and down, thereby further restricting the movement trajectory of the lifting frame and improving the stability of the device.

[0010] In one embodiment of this utility model, a mounting plate is fixedly connected to the outside of the support frame, and a mounting groove is provided on the surface of the mounting plate. This step, by setting the mounting plate and the mounting groove, allows the device to be installed and fixed by screwing bolts into the mounting groove and the mounting location before use, thereby making the device more stable in position during use and further improving the stability of the device during use.

[0011] In one embodiment of this utility model, the inner side of the lifting frame is provided with multiple inclined surfaces, and the lifting frame and the belt are used in conjunction. This step, by setting the lifting frame and the multiple inclined surfaces with different orientations on the inner side of the lifting frame, allows the rotor to be guided by the multiple inclined surfaces with different orientations when the rotor moves to the inner inclined surface of the lifting frame, making it easier for the rotor to be centered and positioned, and to be stably aligned with the first and second rotating wheels, thereby improving the stability of the device.

[0012] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0013] The present invention discloses a motor rotor balance detection device. This device comprises a displacement sensor, a movable component, a spring, and a second wheel. A belt rotates, causing the rotor to move close to a lifting frame. The lifting frame then raises the rotor's shaft, bringing it into contact with a third wheel. The rotor then moves to be flush with the first and second wheels. The first wheel rotates the rotor's shaft, and the spring presses down the movable component, ensuring the second wheel remains flush with the rotor shaft. If the rotor experiences centrifugal force due to misalignment, this force affects the second wheel and is transmitted to the movable component. The displacement sensor monitors the movement of the movable component to ensure rotor balance is within acceptable limits. After detection, the rotor is lowered to the top of the belt to continue moving. This eliminates the need for additional rotor placement and removal, improving the ease of loading and unloading.

[0014] The present invention discloses a motor rotor balance detection device. By setting up a socket, a movable plate, and a plug, when the first motor is connected to the power supply, the socket can be set on the outside of the first motor, and the movable plate and plug can be set on the outside of the lifting frame. The plug is connected to the power supply through a wire. Thus, when the lifting frame drives a rotor to rise, it will drive the movable plate and plug to rise, causing the plug to separate from the socket, thereby cutting off the power to the first motor. This makes it difficult for the belt to drive the undetected rotor on the belt to continue moving, thus reducing the phenomenon of undetected rotors continuing to move and improving the stability of the device's detection.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0024] Reference Figures 1 to 6 As shown, this utility model discloses a motor rotor balance detection device, comprising a support frame 1. A first motor 2 is fixedly connected to the outer side of the support frame 1. A pulley 3 is rotatably connected to the inner side of the support frame 1. A belt 4 is rotatably connected to the outer side of the pulley 3. One pulley 3 is fixedly connected to the output end of the first motor 2. A second motor 5 is fixedly connected to the outer side of the support frame 1. A first rotating wheel 6 is fixedly connected to the output end of the second motor 5. A displacement sensor 7 is fixedly connected to the outer side of the support frame 1. A movable component 8 is slidably connected to the inner side of the support frame 1. A spring 9 is fixedly connected to one end of the movable component 8. One end of the spring 9 is fixedly connected to the support frame 1. A second rotating wheel 10 is rotatably connected to one end of the movable component 8. A hydraulic cylinder 11 is fixedly connected to the outer side of the support frame 1. A lifting frame 12 is fixedly connected to the output end of the hydraulic cylinder 11. A first rotating wheel 10 is rotatably connected to the inner side of the lifting frame 12. The three-wheeled wheel 13; this step involves setting up a displacement sensor 7, a movable component 8, a spring 9, and a second wheel 10. The rotor is moved close to the lifting frame 12 by the rotation of the belt 4. The lifting frame 12 causes the rotor shaft to rise, so that the rotor shaft contacts the third wheel 13 and moves to be close to the first wheel 6 and the second wheel 10. The first wheel 6 drives the rotor shaft to rotate, and the spring 9 causes the movable component 8 to press down, so that the second wheel 10 can always be close to the rotor shaft. Once the rotor experiences centrifugal force due to deviation, the centrifugal force will affect the second wheel 10 and be transmitted to the movable component 8. The displacement sensor 7 monitors the movement of the movable component 8 to ensure that the rotor balance is qualified. After detection, the rotor is moved down to the upper side of the belt 4 to continue moving. There is no need to place and remove the rotor separately, which improves the convenience of loading and unloading the device.

[0025] Reference Figure 1 As shown, a socket 14 is provided on the outside of the first motor 2, and a movable plate 15 is fixedly connected to the outside of the lifting frame 12. A plug 16 is fixedly connected to the outside of the movable plate 15. This step, by setting up the socket 14, the movable plate 15, and the plug 16, allows the first motor 2 to be connected to the power supply. The socket 14 can be set on the outside of the first motor 2, and the movable plate 15 and the plug 16 can be set on the outside of the lifting frame 12. The plug 16 is connected to the power supply through a wire. This allows the movable plate 15 and the plug 16 to be raised when the lifting frame 12 drives a rotor to rise, causing the plug 16 to separate from the socket 14, thereby cutting off the power to the first motor 2. This makes it difficult for the belt 4 to drive the undetected rotor on the upper side of the belt 4 to continue moving, thus reducing the likelihood of the undetected rotor continuing to move and improving the stability of the device's detection.

[0026] Reference Figure 1 and Figure 5As shown, a first gear 17 is fixedly connected to the outer side of one of the pulleys 3. A second gear 18 meshes with the outer side of the first gear 17. The second gear 18 is rotatably connected to the support frame 1. A partition plate 19 is fixedly connected to the side of the second gear 18 that is close to each other. This step, by setting the first gear 17, the second gear 18 and the partition plate 19, ensures that when the pulley 3 rotates, it drives the first gear 17 to rotate. The first gear 17 drives the second gear 18 to rotate. The second gear 18 drives the partition plate 19 to rotate. By placing the rotor at different positions inside the partition plate 19, the rotor can be evenly separated and moved to the upper side of the belt 4, so that the rotors can be evenly distributed and less likely to be too scattered or too concentrated, thus improving the stability of the feeding device.

[0027] Reference Figure 1 and Figure 6 As shown, a third motor 20 is fixedly connected to the outer side of the support frame 1. A threaded screw 21 is fixedly connected to the output end of the third motor 20. A clamping plate 22 is threadedly connected to the outer side of the threaded screw 21. A sliding rod 23 is fixedly connected to the outer side of the clamping plate 22. The sliding rod 23 and the support frame 1 are slidably connected. This step, by setting up the third motor 20, the threaded screw 21, the clamping plate 22, and the sliding rod 23, ensures that when the rotor moves to the upper side of the belt 4, the third motor 20 drives the threaded screw 21 to rotate. The threaded screw 21 drives the clamping plate 22 to move closer to each other, so that the rotor shaft contacts the clamping plate 22. The clamping plate 22 then guides the rotor to the center, making its movement more stable and improving the stability of the device.

[0028] Reference Figure 1 and Figure 6 As shown, a limiting plate 24 is fixedly connected to the outer side of the slide bar 23. The limiting plate 24 and the support frame 1 are used together. By setting the limiting plate 24, when the clamping plate 22 moves to the limit position, the support frame 1 is pressed against the limiting plate 24 to restrict the clamping plate 22. This prevents the clamping plate 22 from getting too close to the belt 4 and causing the belt 4 to be squeezed, which would affect the conveying of the device. This improves the stability of the device.

[0029] Reference Figure 2 and Figure 3 As shown, a limiting rod 25 is fixedly connected to the outside of the lifting frame 12, and the limiting rod 25 is slidably connected to the support frame 1. This step, by setting the limiting rod 25, allows the support frame 1 to restrict the limiting rod 25 when the lifting frame 12 moves up and down, thereby further restricting the movement trajectory of the lifting frame 12 and improving the stability of the device.

[0030] Reference Figure 1As shown, a mounting plate 26 is fixedly connected to the outside of the support frame 1, and a mounting groove 27 is provided on the surface of the mounting plate 26. This step, by setting the mounting plate 26 and the mounting groove 27, allows the device to be installed and fixed by screwing bolts into the mounting groove 27 and the mounting location before use, making the device more stable in use and further improving the stability of the device.

[0031] Reference Figure 3 As shown, the inner side of the lifting frame 12 is provided with multiple inclined surfaces, and the lifting frame 12 and the belt 4 are used in conjunction. This step, by setting the lifting frame 12 and the multiple inclined surfaces with different orientations on the inner side of the lifting frame 12, allows the rotor to be guided by the multiple inclined surfaces with different orientations when the rotor moves to the inner inclined surface of the lifting frame 12, making it easier for the rotor to be centered and positioned, and to be stably aligned with the first rotating wheel 6 and the second rotating wheel 10, thereby improving the stability of the device.

[0032] Working principle: The first motor 2 drives the pulley 3 to rotate, which in turn drives the belt 4 to rotate. The belt 4 then drives the other pulley 3 to rotate, which in turn drives the first gear 17 of the other pulley 3 to rotate. The first gear 17 drives the second gear 18 to rotate, which in turn drives the partition plate 19 to rotate. By placing the rotor at different positions inside the partition plate 19, the rotor can be evenly separated and moved to the upper side of the belt 4. The rotation of the belt 4 drives the rotor to move closer to the lifting frame 12. The hydraulic cylinder 11 drives the lifting frame 12 to rise, which in turn drives the rotor's shaft and the rotor to rise, so that the rotor's shaft connects with the third wheel 13 inside the lifting frame 12. The rotor is moved to be close to the first rotating wheel 6 and the second rotating wheel 10. The four third rotating wheels 13 at both ends work together with the two first rotating wheels 6 at both ends to rotate the rotor shaft. The second motor 5 drives the first rotating wheel 6 to rotate, and the first rotating wheel 6 drives the rotor shaft to rotate. The spring 9 drives the movable component 8 to press down, so that the second rotating wheel 10 can always be close to the rotor shaft. Once the rotor is deviated and centrifugal force occurs, the centrifugal force will affect the second rotating wheel 10 and be transmitted to the movable component 8. The displacement sensor 7 monitors the movement of the movable component 8 to ensure that the rotor balance is qualified. After detection, the rotor is moved down to the upper side of the belt 4 to continue moving.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
