Abstract
Description
Technical Field
[0001] This application relates to the field of electromagnetic coil processing equipment, and more specifically to a winding fixture. Background Technology
[0002] The electromagnetic coil is a crucial component of a solenoid valve, typically made of wound wire. The winding process requires precise control, especially in specialized industries such as coal mining, where the coils are small and the wires used are usually thin, making the winding process more complex and challenging. The winding machine, as a vital piece of equipment for winding electromagnetic coils, plays a crucial role in achieving precise wire winding and improving production efficiency. The winding machine uses mechanical means to evenly wind enameled wire onto a core, completing the fabrication of the electromagnetic coil.
[0003] In existing technologies, during the initial winding of an electromagnetic coil, operators need to manually wind the enameled wire onto the core, ensuring the initial section of the wire is fixed and tensioned. However, due to the instability of manual operation, it is often difficult to guarantee that the tension of the initial section remains consistent. Especially in the early stages of winding, workers may cause the initial section of the enameled wire to loosen due to uneven manual adjustments to the force applied and speed, resulting in changes in the wire tension. Loosening of the initial section leads to uneven distribution of the enameled wire during subsequent winding, potentially causing problems such as scattered wire arrangement and irregular coil shape, affecting the quality of the final product. Utility Model Content
[0004] Therefore, this application provides a winding fixture to solve the problem of unstable initial tension during manual winding in the prior art, which leads to loose wire and uneven winding.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] A winding fixture includes a connecting shaft for connection to a winding machine, a fixture shaft connected to the other end of the connecting shaft for mounting a winding core, a first ring plate connected to one end of the fixture shaft near the connecting shaft, a second ring plate detachably connected to the other end of the fixture shaft for engaging with the first ring plate, and a fixing assembly connected to the connecting shaft for fixing an initial segment of an enameled wire wound on the winding core. A winding core groove is formed between the first ring plate and the second ring plate so that both ends of the winding core abut against the first ring plate and the second ring plate, respectively.
[0007] Optionally, the fixing assembly includes a limiting ring integrally formed on one end of the connecting shaft near the first ring plate and a clamping ring slidably sleeved on the outer wall of the limiting ring. A winding ring groove for winding the initial segment of the enameled wire of the winding core is formed between the limiting ring and the first ring plate. The winding core has a plurality of wire-passing holes for cooperating with the enameled wire along its circumferential direction. The first ring plate has a limiting groove that connects the winding ring groove and the winding core ring groove, so that the initial segment of the enameled wire wound around the winding core passes through the limiting groove from the winding ring groove and winds around the wire-passing holes of the winding core. The clamping ring is used to slide against the groove wall of the winding ring groove near the first ring plate to constrain the enameled wire wound in the winding ring groove. A damping element is connected between the clamping ring and the limiting ring.
[0008] Optionally, the limiting ring has a limiting blind hole, and the damping element includes a spring and a limiting ball disposed in the limiting blind hole. One end of the spring abuts against the bottom wall of the limiting blind hole, and the other end abuts against the limiting ball, so that the limiting ball abuts against the inner ring of the clamping ring.
[0009] Optionally, the central axis of the connecting shaft, the central axis of the tooling shaft, the central axis of the limiting ring, and the central axis of the clamping ring are all collinear, and the annular groove wall of the winding ring groove is connected to a limiting post for winding enameled wire near the limiting groove, and the central axis of the limiting post is perpendicular to the central axis of the connecting shaft.
[0010] Optionally, the first ring plate has a first limiting protrusion formed on the side near the core winding groove for abutting against the core, and the second ring plate has a second limiting protrusion formed on the side near the core winding groove for abutting against the core.
[0011] Optionally, the tooling shaft has a threaded blind hole at one end away from the first ring plate, and the second ring plate is connected to a screw for threaded engagement with the threaded blind hole.
[0012] Optionally, the outer peripheral wall of the second ring plate is formed with anti-slip texture.
[0013] Compared with the prior art, this application has at least the following beneficial effects:
[0014] First, connect the connecting shaft to the winding machine. Then, place the winding core onto the tooling shaft. The first and second ring plates position the winding core, ensuring its stability during the winding process. Next, connect the initial section of enameled wire from the winding machine to the fixing assembly. The fixing assembly secures and tensions the initial section of enameled wire, ensuring it is tightly wound around the winding core and preventing loosening or misalignment.
[0015] After the winding machine is started, the enameled wire begins to gradually wind along the core. The fixing component continuously applies tension to the initial section of the enameled wire to ensure stable tension during the winding process. After the winding is completed, the second ring plate can be removed and a new core can be replaced to continue the next winding operation.
[0016] Compared with the manual winding process commonly used in the prior art, the winding fixture provided in this application can effectively ensure the stability and tension of the initial segment of the enameled wire, avoiding winding quality problems caused by improper manual operation. By controlling the fixing and tension of the initial segment, the winding fixture involved in this application can improve the accuracy and consistency of winding, increase production efficiency, and reduce rework and losses caused by unstable winding quality.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0029] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).
[0030] refer to Figure 1-8 This application discloses a winding fixture, including a connecting shaft 1 for connecting to a winding machine, a fixture shaft 2 connected to the other end of the connecting shaft 1 for sleeved winding core 4, a first ring plate 21 connected to one end of the fixture shaft 2 near the connecting shaft 1, a second ring plate 22 detachably connected to the other end of the fixture shaft 2 for cooperating with the first ring plate 21, and a fixing assembly 3 connected to the connecting shaft 1 for fixing the initial segment of the enameled wire 5 wound on the winding core 4. A winding core 4 annular groove is formed between the first ring plate 21 and the second ring plate 22 to sleeve the winding core 4, so that the two ends of the winding core 4 abut against the first ring plate 21 and the second ring plate 22 respectively.
[0031] First, connect the connecting shaft 1 to the winding machine. Then, place the winding core 4 onto the tooling shaft 2. The first ring plate 21 and the second ring plate 22 position the winding core 4 to ensure its stability during the winding process. Next, connect the initial segment of the enameled wire 5 on the winding machine to the fixing component 3. The fixing component 3 fixes and tensions the initial segment of the enameled wire 5, ensuring that it is tightly wound around the winding core 4 to prevent loosening or misalignment.
[0032] After the winding machine is started, the enameled wire 5 begins to gradually wind along the core 4. The fixing component 3 continuously applies tension to the initial section of the enameled wire 5 to ensure stable tension during the winding process. After the winding is completed, the second ring plate 22 can be removed and a new core 4 can be replaced to continue the next winding operation.
[0033] Compared with the manual winding process commonly used in the prior art, the winding fixture provided in this application can effectively ensure the stability and tension of the initial segment of the enameled wire 5, avoiding winding quality problems caused by improper manual operation. By controlling the fixing and tension of the initial segment, the winding fixture involved in this application can improve the accuracy and consistency of winding, increase production efficiency, and reduce rework and losses caused by unstable winding quality.
[0034] It should be noted that the winding machine, the winding core 4, and the enameled wire 5 are existing technologies and will not be described in detail in this application; in addition, the winding core 4 is also called a skeleton or support, which is mainly used to support the winding of the enameled wire 5 and maintain the shape of the coil.
[0035] The fixing component 3 includes a limiting ring 31 integrally formed on one end of the connecting shaft 1 near the first ring plate 21 and a clamping ring 32 slidably sleeved on the outer wall of the limiting ring 31. A winding ring groove 11 is formed between the limiting ring 31 and the first ring plate 21 for winding the initial segment of the enameled wire 5 of the core 4. The core 4 has a plurality of wire-passing holes 41 that cooperate with the enameled wire 5 along its circumferential direction. The first ring plate 21 has a limiting groove 211 that connects the winding ring groove 11 and the core 4 ring groove, so that the initial segment of the enameled wire 5 winding the core 4 passes through the limiting groove 211 from the winding ring groove 11 and winds around the wire-passing holes 41 of the core 4. The clamping ring 32 is used to slide against the groove wall of the winding ring groove 11 near the first ring plate 21 to constrain the enameled wire 5 wound in the winding ring groove 11. A damping element 6 is connected between the clamping ring 32 and the limiting ring 31.
[0036] Before winding the electromagnetic coil, the enameled wire 5 on the winding machine is first passed through the wire hole 41 on the winding core 4, and then the enameled wire 5 enters the winding ring groove 11 along the limiting groove 211. Next, the enameled wire 5 is wound several times around the ring wall of the winding ring groove 11 to ensure that the initial segment of the enameled wire 5 is correctly guided and fixed. Then, the sliding clamping ring 32 is slid to abut against the groove wall of the winding ring groove 11 near the first ring plate 21, and the clamping ring 32 contacts the groove wall of the winding ring groove 11, thereby clamping the initial segment of the enameled wire 5. In this way, the clamping action between the clamping ring 32 and the first ring plate 21 ensures that the initial segment of the enameled wire 5 maintains a certain tension before winding, ensuring that the initial segment is stable and does not loosen during the winding process, providing a stable foundation for subsequent winding operations.
[0037] The damping element 6 effectively limits the sliding of the clamping ring 32 on the limiting ring 31, preventing it from accidentally loosening or displacing due to external forces or vibrations. The damping element 6 ensures that the clamping ring 32 is always kept in the set position, improving the stability during the winding process.
[0038] In some embodiments, the clamping ring 32 can be threadedly connected to the limiting ring 31. Rotating the clamping ring 32 can cause the clamping ring 32 to move along the length extension direction of the limiting ring 31.
[0039] In some embodiments, the outer diameter of the clamping ring 32 is the same as the outer diameter of the first ring plate 21.
[0040] The limiting ring 31 has a limiting blind hole. The damping element 6 includes a spring 61 and a limiting ball 62 disposed within the limiting blind hole. One end of the spring 61 abuts against the bottom wall of the limiting blind hole, and the other end abuts against the limiting ball 62, so that the limiting ball 62 abuts against the inner ring of the clamping ring 32. Through the elastic force of the spring 61, the limiting ball 62 applies appropriate resistance, preventing the clamping ring 32 from undergoing excessive displacement during sliding, thereby providing appropriate damping force to ensure that the clamping ring 32 can be stably maintained in the predetermined position during winding.
[0041] In some embodiments, the central axis of the connecting shaft 1, the central axis of the tooling shaft 2, the central axis of the limiting ring 31, and the central axis of the clamping ring 32 are all collinear. The annular groove wall of the winding annular groove 11 is connected to a limiting post 12 for winding the enameled wire 5 near the limiting groove 211. The central axis of the limiting post 12 is perpendicular to the central axis of the connecting shaft 1.
[0042] During the winding process, the enameled wire 5 first wraps around the wall of the winding groove 11 several times, and then passes through the limiting post 12 in sequence. After passing the limiting post 12, the enameled wire 5 exits from the limiting groove 211 and enters the wire hole 41, finally winding onto the core 4. Through the action of the limiting post 12, the initial section of the enameled wire 5 is more strongly constrained, further preventing loosening or misalignment during the winding process and ensuring stable tension in the initial section.
[0043] The first ring plate 21 has a first limiting protrusion 212 formed on the side near the annular groove of the core 4 for abutting against the core 4, and the second ring plate 22 has a second limiting protrusion 221 formed on the side near the annular groove of the core 4 for abutting against the core 4.
[0044] During the winding process, both ends of the winding core 4 abut against the first limiting protrusion 212 and the second limiting protrusion 221, respectively, to ensure that the winding core 4 is stably positioned during the winding process. A gap is formed between the winding core 4 and the first ring plate 21, which makes it easy for the operator to manually adjust the position of the winding core 4 so that the wire hole 41 is aligned with the limiting groove 211, and also makes it easy to remove the winding core 4 from the tooling shaft 2.
[0045] The tooling shaft 2 has a threaded blind hole at one end away from the first ring plate 21, and the second ring plate 22 is connected to a screw 222 for threaded engagement with the threaded blind hole.
[0046] The outer peripheral wall of the second ring plate 22 has anti-slip texture.
[0047] In some embodiments, the outer wall of the clamping ring 32 is also formed with anti-slip texture.
[0048] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
[0049] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
