[0002] The rotor of an air conditioner motor is an important component of the air conditioner motor. In the motor, the rotor is the rotating part, which is located inside the stator (the fixed part of the motor) and is supported by bearings to ensure smooth rotation.

[0003] During the assembly of air conditioner motor rotors, precise installation is crucial. However, in small-scale production environments, operators often manually ensure the relative alignment of the rotor and stator, then visually inspect or use a ruler to align them. Once aligned, the rotor and stator assembly is assembled by press-fitting. This results in poor alignment accuracy, making it difficult to maintain consistent pressure, leading to poor motor performance after assembly and easily causing rotor deformation or damage.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0023] The present invention will be further described below with reference to the embodiments. Example

[0024] See also Figures 1-4The adjustment component 4 includes a spring A41 fixedly mounted on the upper surface of the workbench 1, and a placement plate A42 fixedly mounted on the upper end of the spring A41. A placement groove A43 is provided on the upper surface of the placement plate A42, and thread grooves 44 are provided on both sides of the placement plate A42. The interior of each set of thread grooves 44 is threadedly connected with a screw 45, and one end of each set of screws 45 is movably sleeved with a bearing, and the outer surface of each set of bearings is fixedly sleeved with an arc clamp 46. A pressure sensor 47 is provided on the upper surface of the placement plate A42, and the pressure sensor 47 is connected to the control panel 21 signal. By adjusting the screw 45 and the arc clamp 46 to fix the rotor, the rotor can be stably fixed to ensure the accuracy of the pressing process, and the pressure sensor 47 can monitor the pressure changes in real time to ensure the pressing quality.

[0025] The press-fitting assembly 3 includes a hydraulic cylinder 31 fixedly mounted on the upper surface of the frame 2, and a hydraulic rod 32 arranged at the bottom of the hydraulic cylinder 31. One end of the hydraulic rod 32 passes through the interior of the frame 2, and a pressing plate 33 is fixedly mounted on the bottom end of the hydraulic rod 32. The hydraulic cylinder 31 is driven so that the hydraulic rod 32 drives the pressing plate 33 to press down, thereby pressing them together.

[0026] A positioning rod 5 is fixedly installed on the upper surface of the placement plate A42, and one end of the positioning rod 5 passes through the interior of the pressure plate 33 and the frame 2. A spring B51 is fixedly installed between the placement plate A42 and the pressure plate 33, and the spring B51 is sleeved on the outer surface of the positioning rod 5 to provide a positioning effect.

[0027] A fixing assembly 6 for fixing the stator is provided on the upper surface of the workbench 1. The fixing assembly 6 includes a fixing seat 61 fixedly installed on the upper surface of the workbench 1, and a double-threaded rod 62 running through the inside of the fixing seat 61. A fixing plate 63 is fixedly installed on the upper surface of the workbench 1. Two groups of fixing plates 63 are symmetrically arranged. Both ends of the double-threaded rod 62 are rotatably connected to one side of the two groups of fixing plates 63. A servo motor 64 is fixedly installed on one side of one group of fixing plates 63. The output end of the servo motor 64 is fixedly connected to one end of the double-threaded rod 62. The outer surfaces of the positive and negative threads of the double-threaded rod 62 are threadedly connected with a clamping block 65 to fix the stator.

[0028] An electric push rod 66 is fixedly installed on the upper surface of the workbench 1, and a placement plate B67 is fixedly installed on the upper surface of the electric push rod 66. A placement groove B671 is provided on the upper surface of the placement plate B67. The position of the placement plate B67 is adjusted by the electric push rod 66 according to the height of the stator.

[0029] A guide rod 68 is fixedly installed between the two sets of fixing plates 63 , and the guide rod 68 passes through the interior of the two sets of clamping blocks 65 , so that the clamping effect is more stable.

[0030] A circular hole 11 is provided at the center of the workbench 1, and the interior of the circular hole 11 is movably connected to the rotating shaft of the rotor. A mounting bracket 7 is provided at the bottom of the workbench 1, and a laser emitter 71 is provided inside the mounting bracket 7. The laser emitter 71 is located directly below the circular hole 11 and is used to assist in checking whether the stator and rotor are correctly aligned.

[0031] Specifically, the stator is first placed in the placement groove B671 on the upper surface of the placement plate B67, and the position of the placement plate B67 is adjusted by the electric push rod 66 according to the height of the stator. Then, the servo motor 64 is driven to make the two sets of clamps 65 move inward at the same time along the thread direction of the positive thread and the negative thread of the double-threaded rod 62, so that the outer surface of the stator can be clamped and fixed. Then, the rotor is placed between the two sets of arc-shaped clamps 46, and the bottom of the rotor contacts the center of the stator. At the same time, the laser emitter 71 is combined and the screw 45 is rotated. Since the inner and outer rings of the bearing can rotate relative to each other, when the screw 45 rotates, the arc-shaped clamp 46 only moves linearly and does not rotate, so that the arc-shaped clamp 46 can clamp the rotor. To further align the rotor and the stator, the hydraulic cylinder 31 is driven again at this time, so that the hydraulic rod 32 drives the pressure plate 33 to press down, thereby pressing them together, and the pressure sensor 47 can monitor the pressure changes in real time and transmit the data to the control panel 21, so that the working state of the hydraulic cylinder 31 can be adjusted to ensure the pressing quality. In addition, since a positioning rod 5 is fixedly installed on the upper surface of the placement plate A42, one end of the positioning rod 5 passes through the interior of the pressure plate 33 and the frame 2, a spring B51 is fixedly installed between the placement plate A42 and the pressure plate 33, and the spring B51 is sleeved on the outer surface of the positioning rod 5, so it will not affect the displacement of the pressure plate 33, and can also provide a stable positioning effect, making the assembly more accurate.
