The rotor is composed of a rotating shaft, an iron core sleeved on the rotating shaft and a winding wound on the iron core. When the iron core is sleeved on the rotating shaft, assembly tooling is required to assist in the operation.

The rotor assembly tool for the air-conditioning motor has the following advantages over the traditional technology: through the cooperation among the frame, the hydraulic cylinder, the pressure plate and the mounting frame, the rotor core is placed at the center position of the inner bottom end of the slot plate, and then the rotor is inserted into the interior of the square plate. At this time, the centers of the rotor and the rotor core are both located on the same horizontal vertical line, and the rotor core and the rotor can be positioned relatively quickly to reduce the time for calibrating the concentricity of the rotor and the rotor core, which is beneficial to improving work efficiency. Through the cooperation among the frame, the hydraulic cylinder, the pressure plate, the mounting frame and the fine-tuning frame, the installation stability of the rotor and the rotor core is significantly improved, which can provide convenience for the assembly of the air-conditioning motor rotor.

[0004] The above-mentioned and prior art technologies have the following defects: during the process of assembling the air conditioner motor rotor, when the staff takes and places the rotor assembly, the staff's hands will extend under the pressure plate, which may easily cause the pressure plate to crush the staff's hands, posing certain safety hazards.

[0005] Therefore, a rotor assembly tool for an air-conditioning motor is proposed. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rotor assembly tool for an air-conditioning motor, comprising a workbench and a plurality of molds, the upper surface of the workbench is fixedly connected with an electric push rod, the output end of the electric push rod is fixedly connected with a top plate, the inner wall of the mold is clamped and connected with an iron core and a rotating shaft, the surface of the workbench is provided with an adjustment structure, the adjustment structure comprises a rotating rod, the rotating rod is rotatably connected to the workbench, the upper end of the rotating rod is fixedly connected with a rotating plate, the mold is detachably mounted on the upper surface of the rotating plate, the lower end of the rotating rod is fixedly connected with a first gear, the lower surface of the workbench is fixedly connected with a stepping motor, the output end of the stepping motor is fixedly connected with a second gear, and the first gear and the second gear are meshed.

[0008] The effect achieved by the above components is: by setting up the adjustment structure, when assembling the rotor of the air-conditioning motor, the rotating plate that can rotate is used to drive the rotating shaft and the iron core to move, and then the rotating shaft is squeezed with the help of the top plate, so that the rotating shaft is inserted into the iron core along the inner wall of the mold, thereby completing the purpose of assembling the rotor. In this process, the staff's hands do not need to extend between the top plate and the mold, thereby avoiding the situation where the staff's hands are crushed, thereby eliminating safety hazards.

[0012] The effect achieved by the above-mentioned components is: when the first gear and the second gear need to be maintained, pour the lubricating oil into the square box. At this time, the sponge cover will absorb the lubricating oil and make the lubricating oil flow upward along the sponge cover under the influence of capillary effect. Then, slide the connecting plate into the inner wall of the fixed plate. The square box will move with the connecting plate to drive the rotating frame to move. The movement of the rotating frame will drive the sponge cover to move, so that the sponge cover contacts with the teeth of the first gear.

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] like Figure 1-Figure 5 As shown, the utility model provides a rotor assembly tool for an air-conditioning motor, including a workbench 1 and a plurality of molds 4, an upper surface of the workbench 1 is fixedly connected with an electric push rod 2, an output end of the electric push rod 2 is fixedly connected with a top plate 3, an inner wall of the mold 4 is clamped and connected with an iron core 5 and a rotating shaft 6, an adjustment structure 7 is provided on the surface of the workbench 1, and a support structure 8 is provided on the surface of the mold 4.

[0033] The specific settings and functions of the adjustment structure 7 and the support structure 8 are described in detail below.

[0034] like Figure 2-Figure 4As shown, the adjustment structure 7 includes a rotating rod 701, which is rotatably connected to the workbench 1, and the upper end of the rotating rod 701 is fixedly connected to a rotating plate 702. The mold 4 is detachably mounted on the upper surface of the rotating plate 702. The lower end of the rotating rod 701 is fixedly connected to a first gear 703. The lower surface of the workbench 1 is fixedly connected to a stepper motor 704. The output end of the stepper motor 704 is fixedly connected to a second gear 705. The first gear 703 and the second gear 705 are meshed. The lower surface of the rotating plate 702 is rotatably connected to a plurality of balls 706, and the balls 706 are against the upper surface of the workbench 1. The ball bearing 706 can support the rotating plate 702, thereby improving the stability of the rotating plate 702 during operation. The lower surface of the workbench 1 is fixedly connected with a fixed plate 707, and the inner wall of the fixed plate 707 is slidably connected with a connecting plate 708. The surface of the connecting plate 708 is fixedly connected with a square box 709, and the inner wall of the square box 709 is rotatably connected with a rotating frame 710. The surface of the rotating frame 710 is slidably covered with a sponge cover 711, and the sponge cover 711 is against the tooth surface of the first gear 703. When the first gear 703 and the second gear 705 need to be maintained, pour lubricating oil into the square box 70 9, at this time, the sponge cover 711 will absorb the lubricating oil and make the lubricating oil flow upward along the sponge cover 711 under the influence of the capillary effect, and then the connecting plate 708 is slid into the inner wall of the fixed plate 707, and the square box 709 moves with the connecting plate 708 to drive the rotating frame 710 to move, and the movement of the rotating frame 710 will drive the sponge cover 711 to move, so that the sponge cover 711 contacts the teeth of the first gear 703. When the first gear 703 rotates, the lubricating oil in the sponge cover 711 will adhere to the tooth surface of the first gear 703. When the teeth of the first gear 703 with the lubricating oil adhered to When contacting with the teeth of the second gear 705, the lubricating oil will adhere to the tooth surface of the second gear 705, thereby completing the lubrication of the first gear 703 and the second gear 705, and then lubricating the first gear 703 and the second gear 705, extending the service life of the first gear 703 and the second gear 705. The internal thread of the fixing plate 707 is connected with a bolt 712. When the bolt 712 is turned, the bolt 712 will move with the help of the thread and press against the surface of the connecting plate 708. The bolt 712 reaches the position of limiting the connecting plate 708, thereby limiting the position of the square box 709.

[0035] like Figure 5As shown, the supporting structure 8 includes a rectangular frame 81, which is slidably connected to the mold 4. A support plate 82 is fixedly connected to the surface of the rectangular frame 81, and the support plate 82 is in contact with the rotating shaft 6. A spring 83 is fixedly connected to the inner wall of the rectangular frame 81, and one end of the spring 83 is fixedly connected to the mold 4. When the spring 83 contracts, the rectangular frame 81 will slide and reset with the help of the pulling force of the spring 83. A friction plate 84 is fixedly connected to the upper surface of the rotating plate 702, and the friction plate 84 is slidably connected to the rectangular frame 81. Since the rectangular frame 81 is in contact with the friction plate 84, the friction force between the rectangular frame 81 and the friction plate 84 will slow down the sliding speed of the rectangular frame 81, thereby avoiding the contact between the support plate 82 and the top plate 3 during the resetting process of the top plate 3.

[0036] The overall working principle is that when assembling the rotor of the air-conditioning motor, the rotating shaft 6 and the iron core 5 are placed in the mold 4. At this time, the rotating shaft 6 will contact the supporting plate 82, and the supporting plate 82 will support the rotating shaft 6 to prevent the rotating shaft 6 from falling out of the mold 4 due to its own weight, thereby facilitating the subsequent insertion of the rotating shaft 6 into the iron core 5, and then start the stepper motor 704. The rotation of the output end of the stepper motor 704 will drive the second gear 705 to rotate, and the first gear 703 will follow the rotation of the second gear 705 to drive the rotating rod 701 to rotate. The rotation of the rotating rod 701 will drive the rotating plate 702 to rotate. The rotation of the rotating plate 702 will drive the mold 4 to rotate. The rotation of the mold 4 will drive the iron core 5 and the rotating shaft 6 to rotate. When the iron core 5 and the rotating shaft 6 rotate to the top plate 3, open The electric push rod 2, the extension of the output end of the electric push rod 2 will drive the top plate 3 to move, the movement of the top plate 3 will squeeze the shaft 6, and the shaft 6 will be inserted into the iron core 5 along the inner wall of the mold 4, thereby completing the purpose of assembling the rotor. In this process, the staff's hands do not need to extend between the top plate 3 and the mold 4, thereby avoiding the situation where the staff's hands are crushed, thereby eliminating the safety hazard. The movement of the top plate 3 will contact the support plate 82, and the support plate 82 will drive the rectangular frame 81 to slide along the mold 4. The sliding of the rectangular frame 81 will stretch the spring 83. After the assembly is completed, the output end of the electric push rod 2 is controlled to shrink. At this time, the top plate 3 will be out of contact with the support plate 82, so the spring 83 begins to shrink, and the rectangular frame 81 will slide with the help of the pulling force of the spring 83, but because the rectangular frame 81 and the friction The plate 84 contacts, and the friction force between the rectangular frame 81 and the friction plate 84 will slow down the sliding speed of the rectangular frame 81, thereby avoiding the contact between the support plate 82 and the top plate 3 during the resetting process of the top plate 3. Therefore, at this time, the output end of the servo motor can be immediately controlled to continue to rotate, thereby saving the time of waiting for the top plate 3 to be out of contact with the support plate 82, and improving the processing efficiency. During the rotation of the rotating plate 702, the ball 706 can support the rotating plate 702, thereby improving the stability of the rotating plate 702 during operation. When the first gear 703 and the second gear 705 need to be maintained, the lubricating oil is poured into the square box 709. At this time, the sponge cover 711 will absorb the lubricating oil and make the lubricating oil flow upward along the sponge cover 711 under the influence of the capillary effect. Then, the connecting plate 708 is slid into the inner wall of the fixed plate 707. The square box 709 moves with the connecting plate 708 to drive the rotating frame 710 to move. The movement of the rotating frame 710 drives the sponge cover 711 to move. When the sponge cover 711 contacts the teeth of the first gear 703, the bolt 712 is turned. The bolt 712 is moved by the thread and pressed against the surface of the connecting plate 708. The bolt 712 limits the position of the connecting plate 708, thereby limiting the position of the square box 709. When the first gear 703 rotates, the lubricating oil in the sponge cover 711 will adhere to the tooth surface of the first gear 703. When the teeth of the first gear 703 with the lubricating oil attached to them contact the teeth of the second gear 705, the lubricating oil will adhere to the tooth surface of the second gear 705.Thus, the lubrication work of the first gear 703 and the second gear 705 is completed, and the first gear 703 and the second gear 705 are lubricated, thereby extending the service life of the first gear 703 and the second gear 705.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
