Description
Technical Field
[0001] The utility model belongs to the technical field of dynamic balancing of motor rotors, and particularly relates to a device for balancing a motor rotor. Background Art
[0002] Dynamic balancing of a motor rotor is an important link in motor manufacturing and maintenance. The main purpose of dynamic balancing is to reduce the unbalanced force and vibration generated when the motor rotor rotates. When correcting the rotor, it is necessary to determine the position and degree of its imbalance. Then, by adding or removing a certain amount of mass at appropriate positions, the rotor can reach a balanced state.
[0003] When correcting the rotor, if the rotor speed is very high and the centrifugal force is large, and the weight mud is not firmly attached, the weight mud will break away from the high-speed rotating rotor. Due to the action of the centrifugal force, it may fly out at a high speed, which may cause impact injuries to the surrounding personnel. Especially if it hits a critical part, it may cause serious physical injuries. For the surrounding equipment and items, the flying weight mud may damage precision instruments, destroy protective facilities, and even cause failures or damages to other equipment, thus affecting the normal operation of the entire production process or working system.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: including a bottom plate 1, two support plates 11 are installed on the bottom plate 1, a central plate 2 is installed on the support plates 11, two sliding plates 21 are slidably connected to the support plates 11, one side of the sliding plate 21 is slidably connected to a mounting plate 26, two rotating plates 27 are rotatably connected to one side of the mounting plate 26, a mounting ring 28 is snap-connected to the outer wall of the rotating plate 27, four vertical plates 3 are installed on the bottom plate 1, a fixing rod 31 is fixedly connected between every two vertical plates 3, a sliding sleeve 32 is slidably connected to the fixing rod 31, a protective plate 33 is installed between the two sliding sleeves 32, a docking plate 34 is fixedly connected to one end of the protective plate 33, and the inner wall of the docking plate 34 is misaligned with the sliding plate 21 and the mounting ring 28.
[0018] In this implementation: The bottom plate 1 is the carrier of the bearing device. Through the two support plates 11 fixedly connected to the bottom plate 1, the center plate 2 can be supported, enabling the center plate 2 to be at the center of the device, providing an installation surface for the components that can provide rotational force to the motor rotor. The groove formed at the top of the center plate 2 can make way for the motor rotor. When the skateboard 21 slidably connected to the support plate 11 supports the bearing parts at both ends of the motor rotor, the entire part of the motor rotor can be located within the groove formed on the center plate 2, thereby facilitating the adjustment of the motor rotor. The mounting plate 26 slidably connected to one side of the skateboard 21 can mount the rotating plate 27. After the mounting ring 28 is installed on the outer wall of the rotating plate 27, the bearing end of the motor rotor can be supported by the outer walls of two adjacent mounting rings 28. By rotating the rotating plate 27 and the mounting ring 28 on one side of the mounting plate 26, when the motor rotor rotates, the mounting ring 28 can rotate to reduce the friction between it and the motor rotor. After long-term use, when the outer wall of the mounting ring 28 is severely worn, if the mounting ring 28 is continued to be used to detect the dynamic balance of the motor rotor, it will directly affect the accuracy of the dynamic balance detection of the motor rotor. At this time, the mounting ring 28 can be detachably connected to the rotating plate 27. After the mounting ring 28 and the rotating plate 27 are separated, the mounting ring 28 can be quickly replaced. Thus, after replacing the mounting ring 28, it can be ensured that when detecting the dynamic balance of the motor rotor, it can be avoided that the severe wear of the mounting ring 28 causes the motor rotor to shake when being driven to rotate, affecting its normal dynamic balance detection. At the same time, when the device detects the dynamic balance of the motor rotor, since the motor rotor is driven to rotate by the driving component, when detecting the dynamic balance of the motor rotor, the rotor needs to attach the weight mud according to the detection. After the weight mud is attached, the dynamic balance detection needs to be carried out again until the balanced position of the rotor is detected. The weight mud is temporarily installed on the motor rotor. When the rotor rotates for detection, the weight mud is likely to separate from the rotor. At this time, the vertical plate 3 can support the fixed rod 31. The sliding sleeve 32 slidably connected to the fixed rod 31 supports the protection plate 33 at this time. When operating on the motor rotor, the sliding sleeve 32 can slide towards the vertical plate 3, increasing the distance between the two protection plates 33 to make way for the operation on the motor rotor. When the rotor needs to rotate for dynamic balance detection, at this time, the distance between the protection plates 33 can be shortened, enabling one end of the docking plate 34 to be docked, covering the top of the rotor. When the rotor rotates, after the weight mud separates from the rotor at high speed, it can be blocked by the protection plates 33 and the docking plate 34, preventing it from causing great damage to the surrounding staff and precision equipment. Thus, the device is beneficial to the safety work during the detection of the motor rotor.
[0019] There are two fixing plates 12 installed on the bottom plate 1, and the driving ends of the two fixing plates 12 are respectively threadedly connected to the sliding plate 21; the two fixing plates 12 installed on the bottom plate 1 can provide an installation surface for the rotating machine 13, so that the driving end of the rotating machine 13 can correspond to the bottom of the sliding plate 21, and the driving end of the rotating machine 13 can be threadedly connected to the sliding plate 21. Driven by the rotating machine 13, the position of the sliding plate 21 can be adjusted to ensure that the mounting ring 28 can support the rotor bearing according to the rotor model.
[0020] A supporting plate 22 is installed on the outside of the sliding plate 21. A push rod 23 is provided on the supporting plate 22. A support frame 24 is slidably connected to the push rod 23. A tapered groove plate 25 is rotatably connected to the inner wall of the support frame 24; the supporting plate 22 installed on the outside of the sliding plate 21 can support the push rod 23, and the height of the push rod 23 can be adjusted, so that the height of the support frame 24 slidably connected to the push rod 23 can be adjusted to a position corresponding to one end of the motor bearing. Through the tapered groove formed on one side of the tapered groove plate 25 rotatably connected inside the support frame 24, after the tapered groove plate 25 supports one end of the motor rotor, and the tapered groove plate 25 limits one end of the rotor, the tapered groove plate 25 can rotate when the rotor rotates to reduce friction.
[0021] A connecting block 281 is fixedly connected to the mounting ring 28. Corresponding connecting holes 282 are provided on the rotating plate 27 and the connecting block 281; the connecting block 281 fixedly connected to the mounting ring 28 can, after the mounting ring 28 is connected to the rotating plate 27, make the connecting hole 282 provided on the connecting block 281 correspond to the connecting hole 282 provided on the rotating plate 27, so that the connecting holes 282 can be temporarily fixed to the mounting ring 28 under the connection of connecting parts such as clamping blocks.
[0022] The mounting plate 26 is connected to the center plate 2 through a threaded rod, and one end of the push rod 23 is connected to the supporting plate 22 through a threaded rod; the mounting plate 26 is connected to the center plate 2 through a threaded rod, so that the height of the mounting plate 26 can be adjusted by rotating the threaded rod, and similarly, the height of the push rod 23 can be connected to the supporting plate 22 through a threaded rod to adjust its height.
[0023] Working principle and usage process of the present utility model: The motor rotor is mounted on the mounting ring 28. When the outer wall of the mounting ring 28 is severely worn, if the mounting ring 28 is continued to be used for the dynamic balance detection of the motor rotor, it will directly affect the accuracy of the dynamic balance detection of the motor rotor. At this time, the mounting ring 28 and the rotating plate 27 can be detachably connected. After the mounting ring 28 and the rotating plate 27 are separated, the mounting ring 28 can be quickly replaced. After the weight-increasing mud is attached, the sliding sleeve 32 can be pushed to shorten the distance between the two protective plates 33, so that one end of the docking plate 34 is docked, and it is covered on the top of the rotor. When the rotor rotates, after the weight-increasing mud is separated from the rotor under high-speed rotation, it can be blocked by the protective plate 33 and the docking plate 34, preventing it from causing great damage to the surrounding staff and precision equipment, so that the device is beneficial to the safety work during the detection of the motor rotor.
