Description

Technical Field

[0001] The utility model relates to the technical field of rotor coils, and specifically, to a fixing device for a rotor coil. Background Technique

[0002] A rotor coil refers to the coil on the rotor of an electric motor or a generator, which is used to generate a magnetic field or induce an electromotive force in a magnetic field. Such a coil is usually installed on the rotor. As the rotor rotates, it moves in the magnetic field or generates a magnetic field, thereby realizing the rotation of the motor or the generation of electrical energy by the generator.

[0003] When manufacturing a rotor coil, it is necessary to fix it precisely for processing. However, traditional fixing devices usually require manual disassembly and flipping of the rotor coil for multi-sided processing, which not only consumes time and effort but also reduces production efficiency. In addition, traditional fixing methods also have the risk of easily damaging the rotor, bringing unnecessary trouble to the production process.

[0004] In view of this, there is an urgent need to provide a fixing device for a rotor coil to solve the above problems. Content of the Utility Model

[0005] In order to solve the problems that the existing fixing device for a rotor coil is not easy to flip and is prone to damage the rotor, the utility model provides the following technical solution: A fixing device for a rotor coil, including a rotor assembly, the rotor assembly includes a rotating shaft, and a rotor core is arranged on the rotating shaft.

[0006] Among them, it further includes a bracket and a mounting seat. A slide rail is arranged on the bracket, a chute is opened on the slide rail, and a fixed block assembly is slidably connected in the chute. A first electromagnet is arranged on the mounting seat. The fixed block assembly is used to fix the rotating shaft, and the first electromagnet is used to fix the rotor core. Through the sliding connection design of the slide rail and the fixed block assembly, the fixed block assembly can flexibly move along the arc path of the slide rail, which is beneficial to accurately fixing the rotor assembly at different positions or angles, so as to facilitate the all-round processing operation of the rotor core. At the same time, by using the rotational connection design of the first electromagnet and the mounting rod, while fixing the rotor core, the rotating shaft is allowed to rotate around the mounting rod. This design is convenient for rotating and adjusting the rotor core as needed during the processing. Furthermore, it can effectively solve the problems that the existing fixing device for a rotor coil is not easy to flip and is prone to damage the rotor.

[0007] As a further improvement of this technical solution, the slide rail is of an arc structure.

[0008] As a further improvement of this technical solution, the chute matches the slide rail, and the chute is of a T-shaped structure.

[0009] As a further improvement of the technical solution, the fixed block assembly includes a slider, the slider is slidably connected in the chute, the slider matches the chute and the slider is of a T-shaped structure. There is a movable space between the slider and the chute, and a plurality of balls are rotatably connected to the top end of the slider. The balls are in contact with the chute. The bottom end of the slider extends outside the chute, and a second electromagnet is rotatably connected to the end of the slider outside the chute.

[0010] As a further improvement of the technical solution, an installation rod is provided on the mounting seat, and a first electromagnet is rotatably connected to the installation rod.

[0011] As a further improvement of the technical solution, the height position of the first electromagnet is flush with the position of the rotor core on the rotating shaft after the top end of the rotating shaft is fixed on the second electromagnet;

[0012] And the first electromagnet is arranged adjacent to the center position of the slide rail.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For this fixing device of the rotor coil, through the sliding connection design of the slide rail and the fixed block assembly, the fixed block assembly can flexibly move along the arc path of the slide rail, which is beneficial to accurately fix the rotor assembly at different positions or angles, thus facilitating all-round processing operations on the rotor core. Secondly, the use of a T-shaped chute and a T-shaped slider, equipped with balls to reduce friction, not only ensures the stable sliding of the slider in the chute, but also significantly reduces the resistance and wear during the movement, improving the smoothness of the operation. And the rotation connection of the second electromagnet and the slider enables the rotation of the rotating shaft around the central axis of the slider by rotating the rotor core after the adsorption of the first electromagnet is released. This self-rotation function meets the requirements of the self-rotation of the rotor core in a specific processing process, further enhancing the adaptability and processing ability of the device.

[0015] 2. For this fixing device of the rotor coil, through the rotation connection design of the first electromagnet and the installation rod, while fixing the rotor core, the rotating shaft is allowed to rotate around the installation rod. This design facilitates the rotation adjustment of the rotor core according to needs during the processing, thus improving the processing efficiency and flexibility. The setting of the first electromagnet adjacent to the center position of the slide rail enables the rotor core to be conveniently fixed on the first electromagnet and rotated around it after the rotating shaft is fixed.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "multiple" or "several" is two or more, unless otherwise specifically defined.

[0028] Please refer to Figures 1 - 4 As shown, the purpose of this embodiment is to provide a fixing device for a rotor coil, which includes a rotor assembly 2. The rotor assembly 2 includes a rotating shaft 22, and a rotor core 21 is arranged on the rotating shaft 22.

[0029] Furthermore, it also includes a bracket 1 and a mounting base 3. A slide rail 5 is arranged on the bracket 1, a chute 8 is formed on the slide rail 5, a fixed block assembly 6 is slidably connected in the chute 8, a first electromagnet 4 is arranged on the mounting base 3, the fixed block assembly 6 is used to fix the rotating shaft 22, and the first electromagnet 4 is used to fix the rotor core 21.

[0030] First, the specific structure of the slide rail 5 is disclosed. The slide rail 5 is an arc-shaped structure, the chute 8 matches the slide rail 5, and the chute 8 is a T-shaped structure.

[0031] According to the above disclosure of the specific structure of the fixed block assembly 6, the fixed block assembly 6 includes a slider 61. The slider 61 is slidably connected in the chute 8. The slider 61 matches the chute 8 and the slider 61 is a T-shaped structure. There is a movable space between the slider 61 and the chute 8, and a number of balls are rotatably connected to the top end of the slider 61. The balls are in contact with the chute 8. The bottom end of the slider 61 extends outside the chute 8, and a second electromagnet 62 is rotatably connected to the end of the slider 61 located outside the chute 8; the second electromagnet 62 is rotatably connected to the slider 61. In this way, after the first electromagnet 4 releases the fixation on the rotor core 21, the rotor core 21 can be rotated to drive the rotating shaft 22 to rotate around the central axis of the slider 61; in addition, the plug-in fit of the T-shaped chute 8 and the slider 61 can ensure that the slider 61 moves stably along the extension direction of the chute 8. Coupled with a number of balls at the top end of the slider 61, it is used to reduce the friction between the slider 61 and the chute 8 when moving the slider 61.

[0032] According to the above disclosure of the specific structure of the mounting base 3, a mounting rod 7 is arranged on the mounting base 3, and the first electromagnet 4 is rotatably connected to the mounting rod 7.

[0033] According to the above disclosure of the specific positions of the first electromagnet 4 and the fixed block assembly 6, after the height position of the first electromagnet 4 is fixed on the second electromagnet 62 at the top end of the rotating shaft 22, the position of the first electromagnet 4 is flush with the rotor core 21 on the rotating shaft 22;

[0034] And the first electromagnet 4 is arranged adjacent to the center position of the slide rail 5. The reason for this arrangement is that after the rotating shaft 22 is fixed on the second electromagnet 62, the rotor core 21 thereon can be fixed on the first electromagnet 4. Since the first electromagnet 4 is adjacent to the center position of the slide rail 5, when operating such as winding the rotor core 21, the rotating shaft 22 can be rotated so that it can rotate around the first electromagnet 4 through the chute 8.

[0035] The specific working principle is as follows:

[0036] During specific operation, the top end of the rotating shaft 22 of the rotor assembly 2 is fixed to the bottom end of the second electromagnet 62. Start the second electromagnet 62 to fix the rotating shaft 22 on the second electromagnet 62. At this time, the rotor iron core 21 is opposite to the position of the first electromagnet 4. Start the first electromagnet 4 to fix the rotor iron core 21;

[0037] After fixation, operations such as winding the rotor iron core 21 can be carried out. If it is necessary to rotate the rotating shaft 22, only need to push the rotating shaft 22. Because the first electromagnet 4 is rotatably connected to the mounting rod 7, the rotating shaft 22 will drive the rotor iron core 21 to rotate around the mounting rod 7, so as to meet the rotation requirements of the rotating shaft 22 and the rotor iron core 21; If it is necessary to rotate the rotor iron core 21 after operating on one surface of the rotor iron core 21, that is, when the rotor iron core 21 needs to rotate itself, it is necessary to release the adsorption force of the first electromagnet 4, and then rotate the rotor iron core 21 to make it rotate itself, thereby driving the rotating shaft 22 to rotate around the central axis of the slider 61 through the second electromagnet 62, meeting the worker's requirement for the rotor iron core 21 to rotate itself; Furthermore, it effectively solves the problems that the existing rotor coil fixing device is not easy to flip and is easy to damage the rotor.
