[0036] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a motor rotor balancing correction device, which includes a clamping assembly 100, a lifting assembly 200 and a cutting assembly 300.

[0037] Among them, the clamping assembly 100 can clamp the motor rotor; the clamping assembly 100 clamps the motor rotor to prevent it from falling off, and the motor rotor can rotate relative to the clamping assembly 100. After the motor rotor is clamped by the clamping assembly 100, it can be connected to the rotating shaft of the motor rotor through an external drive setting, and the rotation of the motor rotor can be controlled by the external drive setting.

[0038] The lifting assembly 200 includes a base 201 and a screw rod 202 arranged on the base 201, wherein a plurality of supporting legs are also arranged at the bottom of the base 201, and the supporting legs support the base 201 so that the surface of the base 201 is stable, the screw rod 202 is connected to the clamping assembly 100, the screw rod 202 passes through the clamping assembly 100, and the two are connected by a thread, the screw rod 202 can control the lifting and lowering of the clamping assembly 100, wherein the screw rod 202 is rotatably arranged on the base 201, and a motor is arranged on the screw rod 202, and the motor can drive the screw rod 202 to rotate, thereby controlling the lifting and lowering of the clamping assembly 100 threadedly connected to the screw rod 202, wherein the clamping assembly 100 and the base 201 are limited by a limit rod, and when the screw rod 202 rotates, the clamping assembly 100 can slide along the limit rod.

[0039] The cutting assembly 300 includes a mounting frame 301 disposed on the base 201, and a cutter 302 disposed in the mounting frame 301; the cutter 302 cuts the motor rotor, wherein the clamping assembly 100 clamps the motor rotor to prevent it from falling off.

[0040] During use, the motor rotor is clamped by the clamping assembly 100, and then the motor controls the lead screw 202 to rotate, so that the clamping assembly 100 can be raised and lowered, thereby controlling the motor rotor to be raised and lowered, so that it is close to the scraper, and the distance between the motor rotor and the scraper is adjusted. Then, the motor rotor is controlled to rotate by an external drive device, so that the scraper cuts and trims the motor rotor, thereby removing the unbalanced part to achieve the purpose of balancing and correcting the motor rotor.

[0041] Example 2, reference Figure 2 and Figure 3 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the clamping assembly 100 includes two movable sleeves 101, and a clamping portion 102 is arranged on the top of the movable sleeve 101, and the two clamping portions 102 can clamp and fix the rotating shaft of the motor rotor;

[0042] There are two screw rods 202, which are respectively connected to the two movable sleeves 101; the two clamping parts 102 can clamp and limit the rotating shaft at both ends of the motor rotor, and the two movable sleeves 101 and the two clamping parts 102 form a lifting whole with the motor rotor. At the same time, the two movable sleeves 101 are respectively connected to the two screw rods 202, which can move the lifting whole. The simultaneous rotation of the two screw rods 202 can improve the stability and efficiency of the lifting.

[0043] Furthermore, the clamping portion 102 includes a lower sleeve 102a disposed on the movable sleeve plate 101, and an upper sleeve 102b connected to the lower sleeve 102a. The upper sleeve 102b and the lower sleeve 102a can clamp and limit the rotating shaft of the motor rotor.

[0045] The middle part of the upper sleeve 102b and the lower sleeve 102a clamps the shaft of the motor rotor, and the two ends are fixed by bolts. After the upper sleeve 102b and the lower sleeve 102a are fixed together by bolts, the middle part is circular, which can clamp and limit the shaft of the motor rotor. At the same time, the motor rotor can rotate with the upper sleeve 102b and the lower sleeve 102a. When working, first remove the upper sleeve 102b, then put the motor rotor in the two lower sleeves 102a, and finally fix the upper sleeve 102b and the lower sleeve 102a to complete the clamping and limiting of the motor rotor.

[0046] A driving part 203 is provided on the two screw rods 202, wherein the driving part 203 includes a driving motor 203a arranged in the base 201 and connected to one of the screw rods 202, a gear 203b arranged on the two screw rods 202, and a chain 203c sleeved on the two gears 203b. One of the screw rods 202 is driven to rotate by the driving motor 203a, and then the other screw rod 202 is driven to rotate synchronously through the rotation of the chain 203c and the gear 203b, thereby controlling the two movable sleeves 101 to be lifted and lowered synchronously.

[0047] Furthermore, a receiving groove 201a is provided in the base 201, and a concave dust accumulation groove 201b is provided on the surface of the base 201;

[0049] The dust accumulation groove 201b is located below the motor rotor. When the electronic rotor is cut and trimmed, the debris falls into the dust accumulation groove 201b and gathers in the dust accumulation groove 201b, which is convenient for subsequent cleaning.

[0050] The remaining structures are the same as those of Example 1.

[0051] During use, the two clamping parts 102 are used to clamp and limit the motor rotor, and then the two lead screws 202 are controlled to rotate synchronously by driving the motor 203a to drive the two movable sleeves 101 to rise, thereby controlling the motor rotor to approach the scraper, adjusting the distance between the scraper and the motor rotor, and then controlling the motor rotor to rotate and contact the scraper, and the scraper cuts off the excess part to achieve the purpose of balancing the motor rotor.

[0052] Example 3, reference Figure 3 and Figure 4 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the mounting frame 301 includes two support rods 301a and a mounting plate 301b arranged on the top of the support rods 301a; the two support rods 301a are staggered with the movable sleeve 101, and will not interfere with the support rods 301a when the movable sleeve 101 is raised or lowered.

[0053] A telescopic portion 301c is provided between the mounting plate 301b and the cutter 302, wherein the telescopic portion 301c can control the movement of the scraper. The telescopic portion 301c is made of an electric telescopic rod or a cylinder. When the motor rotor is raised or lowered to approach the scraper, coarse adjustment can be made by raising or lowering the motor rotor, and then the scraper can be controlled by the telescopic portion 301c for fine adjustment. The telescopic portion 301c controls the scraper and can accurately control the distance between the scraper and the motor rotor, thereby improving the ability of the motor rotor to balance and correct.

[0054] Furthermore, it also includes a dust accumulation component 400 arranged in the dust accumulation groove 201b; the dust accumulation component 400 includes a dust receiving bin 401, and a roller 402 arranged at the bottom of the dust receiving bin 401. The dust accumulation bin is placed in the dust accumulation groove 201b to collect the removed impurities, and the setting of the roller 402 can better control the dust accumulation bin.

[0055] The remaining structure is the same as that of Example 2.

[0056] During use: use the two clamping parts 102 to clamp and limit the motor rotor, then drive the motor 203a to rotate and control the two screw rods 202 to rotate synchronously, drive the two movable sleeves 101 to rise, thereby controlling the motor rotor to approach the scraper, and then control the telescopic part 301c to control the precise distance between the scraper and the motor rotor, realize coarse adjustment first and then fine adjustment, and finally control the motor rotor to rotate and contact the scraper, and use the scraper to cut off the excess part to achieve the purpose of balancing the motor rotor, and the fallen debris is collected and discharged by the ash storage bin.
