Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of rotor pre-loading technology, and more specifically, to a rotor core loading machine. Background Technology
[0002] The motor rotor is the core component of an electric motor; it refers to the rotating part of the motor used to convert electrical energy into mechanical energy and vice versa. An electric motor consists of two parts: the rotor and the stator, with the stator being the stationary part. Depending on the application, motor rotors can be divided into electric motor rotors and generator rotors. Their main function is to convert electrical energy into mechanical energy, or, in a generator, to convert mechanical energy into electrical energy. The working principle of an electric motor rotor is primarily based on electromagnetic induction. When a conductor on the rotor enters an electric field, the free electrons in the conductor are moved by the electromagnetic force, thus generating an electromotive force and current in the conductor. When the current flows through the conductor, it generates a magnetic field. The magnetic field causes the conductor to move due to the electromagnetic force, thereby achieving rotor rotation.
[0003] On the automated rotor assembly line, the transfer and positioning of the rotor core is a crucial step. Currently, the core is first connected to the rotor shaft by the equipment before proceeding to the next process. However, this process is not continuous, requiring the rotor shaft to be installed before the next process can begin, which creates a drawback in the process connection.
[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rotor core feeding machine, which solves the technical problem that the processing method in the prior art is not continuous, which requires loading and installing the rotor shaft in the middle before loading the next process, resulting in drawbacks in process connection.

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0033] like Figures 1-4 As shown, it illustrates a rotor core feeder according to an embodiment of the present disclosure, comprising:
[0034] A base 1 and a side frame 2, wherein the side frame 2 is fixed to one side of the base 1;
[0035] Feeding insertion assembly 4, which is disposed on the base 1;
[0036] The conveyor belt 3 and the unloading assembly 5 are provided. The conveyor belt 3 is disposed inside the side frame 2, and the unloading assembly 5 is disposed on the base frame and the side frame 2.
[0037] The feeding insertion assembly 4 includes an arc-shaped groove 4-1, which is formed on the surface of the base 1. A feeding rack 4-2 is provided on one side of the base 1, located on one side of the arc-shaped groove 4-1. A discharge rack 4-3 is fixed on the top of the base 1, with circular openings 4-4 at both ends of the discharge rack 4-3. A telescopic hydraulic cylinder 4-5 is fixedly connected to the base 1, and a push rod 4-6 is provided at the output end of the telescopic hydraulic cylinder 4-5. One end of the push rod 4-6 is movably fitted into the circular opening 4-4. The base 1 A first sleeve 4-7 is provided on the side surface, and a second sleeve 4-8 is fixed on the surface of the base 1. Both the first sleeve 4-7 and the second sleeve 4-8 have notches 4-9 at their tops. A telescopic cylinder 4-10 is provided on the side surface of the base 1, and a fixed column 4-11 is provided on the side surface of the base 1. A limit frame 4-12 is movably connected to the fixed column 4-11. The limit frame 4-12 is connected to the output end of the telescopic cylinder 4-10, and the limit frame 4-12 is located between the first sleeve 4-7 and the second sleeve 4-8.
[0038] In some examples, to achieve the effect of quickly inserting the rotor shaft into the iron core, a feeding insertion assembly 4 is designed. An arc-shaped groove 4-1 is opened on the top of the base 1, and a feeding rack 4-2 is set on one side. The iron core can be placed into the feeding rack 4-2 and rolled into the arc-shaped groove 4-1. A discharge rack 4-3 is fixed on the top of the base 1 for placing the rotor shaft. Circular openings 4-4 are opened at both ends. A telescopic cylinder 4-10 and a push rod 4-6 are fixed on the base 1. One end of the push rod 4-6 is located at the circular opening. When extended, the rotor shaft can be inserted into the iron core by pushing the rod 4-6. A first sleeve 4-7 and a second sleeve 4-8 are provided on one side of the base 1. A limit frame 4-12 is provided between the first sleeve 4-7 and the second sleeve 4-8. The limit frame 4-12 is connected to the fixed column 4-11 by the telescopic cylinder 4-10. The telescopic cylinder 4-10 can control the limit frame 4-12 to move up and down. The limit frame 4-12 is used to hold the iron core, so that the rotor shaft can be stably inserted into the iron core.
[0039] like Figures 1-4 As shown, this embodiment proposes the feeding assembly 5, which includes a rolling frame 5-1. The rolling frame 5-1 is fixed on the surface of the base 1 and is located on one side of the second sleeve 4-8. A baffle 5-2 is provided on the side frame 2 and is located at the upper end of the conveyor belt 3. A drive motor 5-3 is fixed on the base 1 and a swing rod 5-4 is provided at the output end of the drive motor 5-3.
[0040] In some examples, in order to achieve the effect of feeding materials into continuous automated equipment, a feeding component 5 is designed. A drive motor 5-3 and a swing rod 5-4 are set on the base 1. When the swing rod 5-4 rotates around the output end of the drive motor 5-3, it can push the iron core in the first sleeve 4-7 to the outside. A rolling frame 5-1 is set on one side of the second sleeve 4-8, which can roll the pushed iron core onto the conveyor belt 3. A baffle 5-2 is set on the top of the conveyor belt 3 to block the iron core and keep it on the conveyor belt 3. The conveyor belt 3 can transport the iron core outward into the next process equipment, thus achieving the feeding effect.
[0041] For example, such as Figure 4 As shown, the thickness of the swing rod 5-4 is smaller than the opening size of the notch 4-9.
[0042] In some examples, by reducing the thickness of the swing arm 5-4, the swing arm 5-4 can pass through the notch 4-9 without obstruction.
[0043] For example, such as Figure 1 As shown, both the feed rack 4-2 and the rolling rack 5-1 are inclined structures.
[0044] In some examples, a tilted structure allows the iron core to roll autonomously without the need for power to push it.
[0045] For example, such as Figure 4 As shown, the upper end of the limiting frame 4-12 has a U-shaped opening structure, and the internal dimensions of the discharge frame 4-3 match the diameter of the rotor shaft.
[0046] In some examples, the U-shaped opening structure facilitates the passage of the swing rod 5-4 and the rotor shaft.
[0047] When processing and feeding are required, the iron core is placed into the feeding rack 4-2 and rolled into the arc groove 4-1. The rotor shaft is placed into the feeding rack 4-2. The telescopic hydraulic cylinder 4-5 is activated, and the bottom rotor shaft is pushed outward and inserted into the iron core by the push rod 4-6. Then, the telescopic air cylinder 4-10 is activated to control the limit frame 4-12 to descend. After descending, the drive motor 5-3 is activated, and the swing rod 5-4 passes through the notch 4-9 to push the iron core into the rolling frame 5-1. The iron core rolls into the conveyor belt 3 and passes through the baffle 5-2 assembly. Finally, the conveyor belt 3 is activated to transport the iron core and drop it into the next process to achieve the feeding effect.
