Description

Technical Field

[0001] This utility model relates to the field of rotor core slab handling technology, and more specifically, to a tooling for handling cast aluminum rotor core slabs. Background Technology

[0002] In the field of traditional induction motor rotor core production, rotor core manufacturing, through the coordination of mold design and equipment, can achieve overall material cutting according to customer requirements, demonstrating high production efficiency and automation.

[0003] However, the existing rotor core lamination tooling has the following problems when in use:

[0004] To meet customers' specific requirements for rotor skewness and adapt to subsequent aluminum casting processes, most rotor cores still rely on manual, single-piece cutting. This process not only requires a significant amount of manpower to separate the rotor cores one by one but also to precisely align them in the same direction. Due to this inefficient single-piece cutting method, a large amount of manual labor is required in the rotor core sorting process, making subsequent processes in the entire production flow cumbersome and complex, and significantly increasing labor costs. This not only limits the improvement of production efficiency but also imposes a heavy economic burden on enterprises.

[0005] This invention can replace manual single-piece separation and alignment of the rotor core in one direction, reducing manpower requirements while significantly improving production efficiency. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a tooling for arranging cast aluminum rotor core plates.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tooling for arranging cast aluminum rotor core laminations, comprising: a base plate, a motor fixedly mounted on one side above the base plate, a rotating shaft rotatably mounted above the base plate, a fixed shaft fixedly mounted in front of the rotating shaft, a side plate fixedly mounted on the upper end of the base plate, a motor plate fixedly mounted in the middle of the outer end face of the side plate, the motor fixedly mounted on the upper end of the motor plate, the fixed shaft fixedly mounted on the side plate, and the rotating shaft located behind the fixed shaft and passing through the side plate and fixedly connected to the motor.

[0008] A further preferred embodiment: the upper right side of the base plate and the middle of the side plate are provided with screw holes, the base plate is fixedly connected to the side plate by bolts passing through the screw holes, and the middle of the side plate is fixedly connected to the motor plate by bolts passing through the screw holes.

[0009] A further preferred embodiment: a through hole is provided on the side plate, the through hole is matched with the rotating shaft, and the rotating shaft passes through the through hole and is fixedly connected to the motor.

[0010] A further preferred embodiment: a coupling is fixedly installed at the output end of the motor, and the other end of the coupling is fixedly connected to the rotating shaft.

[0011] A further preferred embodiment: the centers of the rotating shaft and the fixed shaft are at the same plane height.

[0012] A further preferred embodiment: a self-lubricating bearing is provided at the contact point between the rotating shaft and the through hole on the side plate, wherein the inner ring of the self-lubricating bearing is tightly fitted with the rotating shaft, and the outer ring is tightly fitted with the through hole.

[0013] Beneficial effects:

[0014] 1. By setting up a rotating shaft and a fixed shaft, with the centers of the rotating shaft and the fixed shaft at the same plane height, the center of gravity of the tooling is evenly distributed, reducing tilting and shaking, enhancing operational stability, and ensuring accurate and reliable wafer sorting operation. During the wafer sorting process, this design makes the relative movement of the rotor core and the two shafts smoother, avoiding abnormal friction and wear caused by height differences, extending the service life of the fixed shaft, rotating shaft, and rotor core, and reducing tooling maintenance costs. The rotation of the rotating shaft drives the cast aluminum rotor core sleeved on the fixed shaft to sort, making the arrangement of each core more neat.

[0015] 2. Equipped with a motor and coupling, the motor serves as the core power source, providing driving force for the rotation of the rotating shaft, which in turn drives the cast aluminum rotor core to assemble. Its stable operation ensures continuous and efficient wafer assembling. One end of the coupling is connected to the motor output, and the other end is connected to the rotating shaft. It can effectively buffer the strong impact generated when the motor starts and stops, protecting the precision components inside the motor and the rotating shaft from damage by instantaneous impact force, and extending the service life of both. At the same time, the coupling can compensate for the coaxiality error between the motor output shaft and the rotating shaft. Even if there are slight deviations between the two shafts during installation or operation, it can ensure smooth and unobstructed power transmission, avoiding jamming and vibration caused by coaxiality problems, making the tooling operation more stable and reliable, and greatly improving work efficiency and wafer assembling quality.

[0016] 3. By incorporating through holes and self-lubricating bearings, the through holes on the side plate are matched with the rotating shaft, providing precise installation and positioning for the rotating shaft. This ensures good alignment after installation, preventing abnormal rotation due to installation deviations. Simultaneously, the through holes effectively guide the rotating shaft during tooling operation, making its trajectory more stable and preventing radial runout or axial movement during rotation. This ensures uniform force on the cast aluminum rotor core during lamination, improving lamination quality. The inner ring of the self-lubricating bearing fits tightly with the rotating shaft, while the outer ring is tightly connected to the through hole. During shaft rotation, this significantly reduces friction between the rotating shaft and the through hole, making the motor drive the rotating shaft more smoothly, reducing motor energy consumption and operating costs. Furthermore, the self-lubricating bearings possess excellent wear resistance and corrosion resistance, adapting to complex working environments, reducing component damage caused by friction and corrosion, extending tooling lifespan, reducing maintenance frequency and costs, and ensuring long-term stable operation of the tooling.

[0017] 4. In summary, this type of cast aluminum rotor core lamination fixture, through the inclusion of a motor, coupling, rotating shaft, fixed shaft, through hole, and self-lubricating bearing, provides the core power for the entire fixture's operation. The coupling buffers the impact of motor start-up and stop, compensates for coaxiality errors between shafts, and ensures smooth power transmission. The coordinated operation of the rotating and fixed shafts ensures that the cast aluminum rotor core can be stably placed during the lamination process, while also achieving efficient lamination through the rotation of the rotating shaft. Furthermore, since the centers of the two shafts are at the same plane height, the fixture's operational stability is improved, and component wear is reduced. The through hole creates conditions for precise installation and stable rotation of the rotating shaft, while the addition of the self-lubricating bearing further reduces rotational friction and improves motor drive efficiency. Simultaneously, its excellent wear resistance and corrosion resistance significantly extend the fixture's service life and reduce maintenance costs. Attached Figure Description

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-3 In this embodiment of the present invention, a tooling for arranging cast aluminum rotor core laminations includes: a base plate 1; a motor 2 fixedly mounted on one side above the base plate 1; a rotating shaft 3 rotatably mounted above the base plate 1; a fixed shaft 4 fixedly mounted in front of the rotating shaft 3; a side plate 101 fixedly mounted on the upper end of the base plate 1; a motor plate 102 fixedly mounted on the middle of the outer end face of the side plate 101; the motor 2 fixedly mounted on the upper end of the motor plate 102; the fixed shaft 4 fixedly mounted on the side plate 101; and the rotating shaft 3 located behind the fixed shaft 4 and passing through the side plate 101 to connect with the motor. 2. Fixed connection: Screw holes 103 are provided on the upper right side of the base plate 1 and in the middle of the side plate 101. The base plate 1 is fixedly connected to the side plate 101 by bolts 104 passing through the screw holes 103. The middle of the side plate 101 is fixedly connected to the motor plate 102 by bolts 104 passing through the screw holes 103. A through hole 105 is provided on the side plate 101, which is matched with the rotating shaft 3. The rotating shaft 3 passes through the through hole 105 and is fixedly connected to the motor 2. A coupling 201 is fixedly installed at the output end of the motor 2, and the other end of the coupling 201 is connected to the rotating shaft 3. The cast aluminum rotor cores are sequentially fitted onto the fixed shaft 4. Since the centers of the rotating shaft 3 and the fixed shaft 4 are at the same plane height, the cast aluminum rotor cores can be smoothly arranged during the chip sorting process, and the stability of subsequent operations is good. When the power supply of the motor 2 is turned on, the motor 2 starts to run. The power of the motor 2 is transmitted to the rotating shaft 3 through the coupling 201, causing the rotating shaft 3 to start rotating. The coupling 201 can effectively buffer the impact generated when the motor 2 starts and stops, protecting the motor 2 and the rotating shaft 3 from damage. At the same time, it can also compensate for the coaxiality error between the rotating shaft 3 and the output shaft of the motor 2, ensuring the smooth transmission of power and improving the service life and working reliability of the tooling. The rotating shaft 3 passes through the through hole 105 on the side plate 101. Since the through hole 105 is matched with the rotating shaft 3, it can ensure the stability of the rotation of the rotating shaft 3. The rotation of the rotating shaft 3 drives the cast aluminum rotor cores fitted onto the fixed shaft 4 to be sorted. Under the action of the rotating shaft 3, the cast aluminum rotor cores will gradually adjust their positions, making the arrangement of each cast aluminum rotor core more neat.

[0024] In this embodiment of the invention, the centers of the rotating shaft 3 and the fixed shaft 4 are at the same plane height. This makes the overall center of gravity distribution of the tooling more uniform during operation, reducing the tilting or shaking of the tooling caused by the inconsistency in the height of the two shafts, enhancing the stability of the tooling during operation, and further ensuring the accuracy and reliability of the sheet handling operation. During the process of the rotating shaft 3 driving the sheet handling to be arranged around the fixed shaft 4, the same plane height makes the relative movement between the rotor core and the fixed shaft 4 and the rotating shaft 3 smoother, avoiding abnormal friction and wear caused by height difference, extending the service life of the fixed shaft 4, the rotating shaft 3 and the rotor core itself, and reducing the tooling maintenance cost.

[0025] In this embodiment of the present invention, a self-lubricating bearing is provided at the contact point between the rotating shaft 3 and the through hole 105 on the side plate 101. The inner ring of the self-lubricating bearing is tightly fitted with the rotating shaft 3, and the outer ring is tightly fitted with the through hole 105. The self-lubricating bearing can automatically provide lubrication during the rotation of the rotating shaft 3, reducing the friction between the rotating shaft 3 and the through hole 105. This makes the rotation of the rotating shaft 3 by the motor 2 smoother, reduces the load on the motor 2, and improves the working efficiency of the tooling. At the same time, the smooth rotation also helps to ensure the sorting effect of the cast aluminum rotor core laminations, improves the quality of the laminations, and can also effectively limit the radial and axial displacement of the rotating shaft 3, enhancing the stability of the rotation of the rotating shaft 3. During the lamination process, the stable rotation of the rotating shaft 3 can ensure that the laminations are subjected to uniform force, avoiding the situation where the laminations are not neatly arranged due to the shaking of the rotating shaft.

[0026] Working principle: The cast aluminum rotor core is sequentially fitted onto the fixed shaft 4. Since the centers of the rotating shaft 3 and the fixed shaft 4 are at the same plane height, the casting aluminum rotor core is fitted smoothly during the process, providing a stable foundation for subsequent sheet handling. When the power to the motor 2 is turned on, the motor 2 starts running. The power of the motor 2 is transmitted to the rotating shaft 3 through the coupling 201. The coupling 201 effectively buffers the impact generated when the motor 2 starts, protecting the motor 2 and the rotating shaft 3 from damage. It also compensates for the coaxiality error between the rotating shaft 3 and the output shaft of the motor 2, ensuring smooth power transmission. The rotating shaft 3 passes through the through hole 105 on the side plate 101. The self-lubricating bearing, which is matched with the rotating shaft 3 and is in contact with the through hole 105, can automatically provide lubrication, reducing the friction between the rotating shaft 3 and the through hole 105, making the rotating shaft 3 rotate more smoothly, reducing the load on the motor 2. The self-lubricating bearing can also limit the radial and axial displacement of the rotating shaft 3, enhancing the stability of the rotating shaft 3. The stable rotation of the rotating shaft 3 drives the cast aluminum rotor core sleeved on the fixed shaft 4 to be aligned. Under the action of the rotating shaft 3, the cast aluminum rotor core gradually adjusts its position, and the arrangement between each cast aluminum rotor core is more neat. After the cast aluminum rotor core is aligned, the power of the motor 2 is turned off, and the rotation of the rotating shaft 3 is stopped.
