Description

Technical Field

[0002] In the field of motor manufacturing, the coil, as the core component for electromagnetic conversion in a motor, directly affects the motor's energy efficiency, operational stability, and service life. During coil winding, the stable control of the tension on the conductor is a key factor in ensuring coil quality. Appropriate tension ensures tight conductor arrangement and uniform winding, reduces stress concentration within the coil, and improves the overall performance of the motor. As motors develop towards higher efficiency, miniaturization, and precision, the precision requirements for coil winding are increasing, especially in high-end fields such as new energy vehicle motors and industrial servo motors, where strict control of coil tension within a minimal fluctuation range is necessary. Currently, the industry has developed various motor coil tension adjustment technologies, covering mechanical friction adjustment, pneumatic control, and electromagnetic braking. These technologies achieve dynamic adjustment of conductor tension through different mechanical principles and are widely used in various motor production scenarios, providing technical support for the stable mass production of motor coils.

At the same time, some high-precision devices often adopt complex structural designs to achieve fine adjustment, resulting in high manufacturing costs and making it difficult to popularize in small and medium-scale production scenarios. There is an urgent need for a solution that balances stability and economy. Utility Model Content

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a motor coil tension adjustment device, including a support rod 1, a buffer 2, a main frame 3, a slider 5, a spring 202, and a guide wheel 601. Two sets of circular holes are provided in a square groove on one side of the main frame 3. Two sets of circular heads are provided at the tail of the support rod 1, and the tail of the support rod 1 is rotatably connected to the square groove on one side of the main frame 3 via the circular heads. Two sets of connecting plates are provided on one side of the main frame 3. A set of circular heads is provided on each side of the tail of the buffer 2, and the tail of the buffer 2 is rotatably connected to the connecting plate on one side of the main frame 3 via the circular heads. Three sets of square through grooves are provided on the main frame 3, and a set of T-shaped sliding grooves are provided on each side of the square through grooves on the main frame 3. A set of T-shaped blocks are provided on each side of the slider 5, and the slider 5 is slidably connected to the square through grooves on the main frame 3 on both sides. A set of threaded circular holes is provided at the lower part of the main frame 3. A set of threaded circular heads is provided on one side of the guide 6, and the guide 6 is fastened to the lower part of the main frame 3 on one side. A set of circular holes is provided on each side of the lower part of the main frame 3, and the guide 6 is rotatably connected to the lower part of the main frame 3.

[0028] The main frame 3 has a set of threaded circular holes on the upper part of the square groove inside, and a set of threaded rods 4 are rotatably connected to each of the threaded circular holes on the upper part of the square groove inside the main frame 3. The top of the slider 5 has a set of circular grooves, and the top circular groove of the slider 5 is rotatably connected to the bottom of the threaded rods 4. When the threaded rods 4 are rotated, their bottoms rotate in the top circular groove of the slider 5, which drives the slider 5 to slide smoothly along the T-shaped slide groove of the main frame 3, accurately changing the position of the damping wheel 502, realizing fine adjustment of the coil tension, and ensuring adjustment stability.

[0029] The slider 5 has four sets of square locking blocks on its outer side, and a cover plate 501 is attached to the square locking blocks on its outer side. Both the slider 5 and the cover plate 501 have a set of circular holes, and a damping wheel 502 is rotatably connected to the circular holes on the slider 5 and the cover plate 501. The square locking blocks allow the cover plate 501 to be quickly locked and fixed, and it is convenient to disassemble and install for maintenance of the damping wheel 502. The circular holes of both support the damping wheel 502 to rotate stably, ensuring that the coil wire is subjected to uniform force when in contact, and improving the tension adjustment accuracy.

[0030] The main frame 3 has two sets of T-slots on one side, and each T-slot on the main frame 3 is fitted with a measuring rod 7. The T-slots allow the measuring rod 7 to be securely fitted and easy to adjust its position. The measuring rod 7 can be used to visually monitor the offset of the coil wire, correct the wire direction in time, avoid abnormal tension due to position deviation, and ensure winding accuracy.

[0031] The support rod 1 has a set of circular holes at its head, and a wire wheel 101 is rotatably connected to the circular holes at the head of the support rod 1. A set of connecting rods 102 is welded in the middle of the wire wheel 101. The circular holes allow the wire wheel 101 to rotate flexibly, reducing friction damage to the wire. The connecting rods 102 link the wire wheel 101 with the buffer 2. When the wire tension changes, the buffer 2 is driven to work, realizing instant buffering of tension fluctuations and ensuring tension stability.

[0032] The buffer 2 has a set of circular grooves inside, and a set of telescopic rods 201 are telescopically connected inside the circular grooves of the buffer 2. A spring 202 is movably connected inside the buffer 2 and at the bottom of the telescopic rods 201. The spring 202 undergoes elastic deformation as the telescopic rods 201 extend and retract, which can absorb the energy of instantaneous tension fluctuations. In conjunction with the extension and retraction of the telescopic rods 201, it effectively buffers the tension impact of the conductor and maintains tension stability.

[0033] The main frame 3 has two sets of connecting slots on one side and two sets of cross connecting slots at the bottom. The two sets of connecting slots can be flexibly equipped with auxiliary components to expand the function of the device. The bottom cross connecting slot can be quickly fixed to the workbench to ensure that the device is stable and does not shake during operation, providing a stable foundation for coil tension adjustment and improving the overall working reliability.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, the device is fixed to the workbench via the cross-shaped connecting groove at the bottom of the main frame 3, ensuring overall stability. The coil wire is sequentially wound around the wire wheel 101 at the head of the support rod 1, the damping wheel 502 between the slider 5 and the cover plate 501, and the guide wheel 601 on the guide 6 to form a complete wire path. When tension needs to be adjusted, the threaded rod 4 at the top of the square groove of the main frame 3 is rotated, and its bottom drives the slider 5 to slide along the T-shaped groove in the square through groove of the main frame 3, changing the relative position of the damping wheel 502 with the wire wheel 101 and the guide wheel 601, thereby adjusting the tension on the wire. During the winding process, if the wire tension fluctuates, the support rod 1 will link the buffer 2 through the connecting rod 102 in the middle of the wire wheel 101, causing the telescopic rod 201 in the buffer 2 to extend and retract in the circular groove, which, together with the spring 202, buffers the tension impact and reduces the impact of instantaneous tension changes on the coil. The measuring rod 7 on one side of the main frame 3 allows for direct observation of the wire position deviation, facilitating timely correction. The cover plate 501 is fixed by the square clip on the outside of the slider 5, providing protection for the damping wheel 502. The connecting slot on one side of the main frame 3 can be expanded with additional components as needed, enhancing the applicability of the device and enabling stable adjustment and convenient operation of the coil tension.
