Description

Technical Field

[0001] The invention belongs to the technical field of rotor core processing, and more specifically, particularly relates to a rotor core winding device. Background Art

[0002] The "rotor core" is an important component of the motor, usually referring to the iron core installed on the rotor shaft, which can enhance the magnetic field strength of the motor. The rotor core winding equipment is a mechanical equipment specially designed for winding coils on the rotor core. It usually includes motor drive, wire supply, winding mechanism, control system and other parts. However, the current rotor core winding equipment is generally divided into fully automatic or semi-automatic equipment. Fully automatic equipment can automatically complete the winding and fixing of the coil, greatly improving the production efficiency and the quality of the coil, while semi-automatic equipment requires manual participation in some operations. Although the production efficiency and coil quality are slightly lower than those of fully automatic equipment, the cost is lower and it is suitable for small-scale production. Different types of equipment can be selected according to actual production needs to achieve the best production effect and economic benefits.

[0003] When the existing rotor core frame is winding copper wire, due to the different materials of some copper wires, the required tension is also different. Otherwise, the copper wire of the rotor core frame will not be tightly wound when winding the copper wire, which is easy to affect the overall structural strength of the rotor and may also have an adverse effect on the electromagnetic performance. However, at present, the existing equipment cannot provide tension for the copper wire in the winding area of ​​the winding equipment, and often provides additional tension during the transmission process of the copper wire. Therefore, the copper wire tension is easily uneven in the diffraction area between the copper wire and the rotor core frame, especially in the area with a large diffraction angle or a complex diffraction path, which is prone to loose problems. The practicality is insufficient and needs to be improved.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a winding device for a rotor core is provided, in order to achieve a more practical purpose. Summary of the invention

A winding unit 24 is fixedly installed on the side wall of the slip ring 23. By setting the slide groove 13 and the annular groove 22, when the staff adjusts the position of the roller unit 17 on the square sliding seat 15 and the winding unit 24 rotates, the square sliding seat 15 will drive the square groove 12 and the slide groove 13 to slide respectively through the slider 14, and the winding unit 24 drives the slip ring 23 to slide inside the annular groove 22, so as to provide additional limit and increase stability. By rotating the threaded rod 16, the threaded rod 16 and the square sliding seat 15 are threadedly driven, so that the square The square sliding seat 15 drives the slider 14 to slide in the square groove 12 and the slide groove 13 respectively.

Between the guide blocks 29, the second U-shaped block 31 is fixedly installed with the guide blocks 29, and the side walls of the second U-shaped block 31 are symmetrically provided with fasteners 32. The second U-shaped block 31 is placed between the through grooves 27 according to the characteristics of the copper wire on the copper wire roller 33, and a position that can maintain a suitable tension with the rotor core winding frame 18 is selected to slide the second U-shaped block 31 inside the guide groove 28. At this time, the second U-shaped block 31 will drive the guide block 29 to slide inside the guide groove 28. When it moves to a position that can maintain a suitable tension with the rotor core winding frame 18, the staff can pick up the connecting rod 37 and insert the pin 36 into the first slot 34 on the first U-shaped block 26, so as to preliminarily adjust the tension of the copper wire roller 33 wrapped around the rotor core winding frame 18, thereby improving the winding tension and increasing practicality.

[0038] A copper wire roller 33 is rotatably installed between the two fasteners 32, each first slot 34 is opened in the first U-shaped block 26, each first slot 34 is communicated with the through slot 27, each second slot 35 is opened in the guide block 29, each second slot 35 is adapted to the first slot 34, a bayonet 36 is located in the first slot 34 and the second slot 35, the bayonet 36 is engaged with the first slot 34 and the second slot 35, each bayonet 36 is partially exposed above the first U-shaped block 26, a connecting rod 37 is fixedly installed between the two bayonet pins 36, and the bayonet pins 36 are arranged to be inserted into the first slot 34 on the first U-shaped block 26 and the second slot 35 of the guide block 29, so that the staff can disassemble the second U-shaped block 31 as a whole after use, and replace the copper wire roller 33 as a whole of different models, thereby further improving portability.

[0039] Working principle:

[0040] The first step is that when in use, the staff can first load the copper wire roller 33 adapted to the winding bracket 19 into the inner side of the second U-shaped block 31 using the fastener 32, and then the staff can put the second U-shaped block 31 between the through grooves 27 according to the characteristics of the copper wire on the copper wire roller 33, and select a position that can maintain a suitable tension with the rotor core winding frame 18 to slide the second U-shaped block 31 inside the guide groove 28. At this time, the second U-shaped block 31 will drive the guide block 29 to slide inside the guide groove 28. When it moves to a position that can maintain a suitable tension with the rotor core winding frame 18, the staff can pick up the connecting rod 37 and insert the bayonet 36 into the first bayonet groove 34 on the first U-shaped block 26. Then the bayonet pin 36 may not be directly inserted into the second bayonet groove 35 of the guide block 29 inside the guide groove 28. At this time, the staff can slightly adjust and move the second U-shaped block 31 until the bayonet pin 36 can be inserted into the first bayonet groove 34 and the second bayonet groove 35.

[0041] By placing the second U-shaped block 31 between the through grooves 27 according to the characteristics of the copper wire on the copper wire roller 33, and selecting a position that can maintain appropriate tension with the rotor core winding frame 18 to slide the second U-shaped block 31 inside the guide groove 28, the second U-shaped block 31 will drive the guide block 29 to slide inside the guide groove 28. When it moves to a position that can maintain appropriate tension with the rotor core winding frame 18, the staff can pick up the connecting rod 37 and insert the pin 36 into the first slot 34 on the first U-shaped block 26, so as to preliminarily adjust the tension of the copper wire roller 33 wrapped around the rotor core winding frame 18, thereby improving the winding tension and increasing practicality.

[0042] In the second step, the staff can then put the rotor core winding frame 18 between the roller units 17, and manually pre-wind the copper wire on the copper wire roller 33 with the rotor core winding frame 18. After the winding is completed, the staff can find that the copper wire and the rotor core winding frame 18 are relatively loose. At this time, the staff can rotate the threaded rod 16 to make the threaded rod 16 and the square sliding seat 15 have threaded transmission, so that the square sliding seat 15 drives the slider 14 to slide in the square groove 12 and the slide groove 13 respectively. At this time, the movement of the square sliding seat 15 will drive the roller unit 17 and the rotor core winding frame 18 to move together. When the copper wire connected to the rotor core winding frame 18 is tightened, the staff can stop rotating the threaded rod 16;

[0043] By rotating the threaded rod 16, the threaded rod 16 and the square sliding seat 15 are threadedly transmitted, so that the square sliding seat 15 drives the slider 14 to slide in the square groove 12 and the sliding groove 13 respectively. At this time, the movement of the square sliding seat 15 will drive the roller unit 17 and the rotor core winding frame 18 to move together. When the copper wire connected to the rotor core winding frame 18 is tightened, the staff can stop rotating the threaded rod 16 at this time, thereby avoiding insufficient tension of the copper wire roller 33 winding around the rotor core winding frame 18 due to the small tension adjustment space inside the C-shaped ring 25, thereby completing further adjustment and improving practicality.

[0044] In the third step, the staff can then turn on the winding drive unit 21 and the roller unit 17, so that the gear on the winding drive unit 21 is meshed with the rack of the winding unit 24, so that the winding unit 24 drives the slip ring 23 to slide inside the ring groove 22, and at the same time, the rotation of the winding unit 24 will drive the C-shaped ring 25 and the first U-shaped block 26 and the second U-shaped block 31 on the C-shaped ring 25 to rotate, and at the same time, the copper wire on the copper wire roller 33 will circle around the rotor core winding frame 18, so that the copper wire is wound on the rotor core winding frame 18, and at the same time, the opening of the roller unit 17 will drive one of the roller units 17 to rotate, and then drive the rotor core winding frame 18 to rotate, so that each position on the rotor core winding frame 18 can fully diffract with the copper wire;

[0045] By setting the slide groove 13 and the ring groove 22, when the staff adjusts the position of the roller unit 17 on the square sliding seat 15 and rotates the winding unit 24, the square sliding seat 15 will drive the square groove 12 and the slide groove 13 to slide respectively through the slider 14, and the winding unit 24 will drive the slip ring 23 to slide inside the ring groove 22, thereby providing additional limiting and increasing stability.

[0046] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
