Technical Field

[0001] The utility model relates to the technical field of winding fixtures, and more specifically, to a winding fixture for an elongated stator core. Background Art

[0002] The stator core is an important part of the magnetic circuit of an electric motor. Together with the rotor core and the air gap between the stator and the rotor, it forms a complete magnetic circuit of the electric motor. The stator winding fixture is a tool used to assist in winding the stator, and its main function is to provide support and positioning for the stator winding to ensure the accuracy, consistency, and efficiency of the winding.

[0003] Regarding the existing technology, the following problems exist:

[0004] In the existing technology, when the winding fixture positions the stator core, it often can only perform positioning restrictions according to workpieces of a single size model. When processing workpieces of different sizes, the positioning tool needs to be replaced separately. This process is time-consuming, and the disassembly and assembly steps are rather cumbersome, making it inconvenient for people to operate. Summary of the Utility Model

[0005] In view of the problems in the related art, the present utility model proposes a winding fixture for an elongated stator core to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To this end, the specific technical solution adopted by the present utility model is as follows:

[0007] A winding fixture for an elongated stator core includes an outer protection component and a support plate. The outer protection component and the support plate are fixedly connected to each other. A placement groove is formed at the center of the surface of the support plate. Positioning components are arranged on both sides of the placement groove. The positioning components include rectangular blocks. A return spring is arranged on the surface of the rectangular block. The top end of the return spring is fixedly connected to a fixed clamping block. The number of the fixed clamping blocks is four groups, and they are distributed in a circumferential array on the outer wall of the rectangular block. The four groups of fixed clamping blocks are designed in a "V" shape, and the "V" opening sizes of the four groups of fixed clamping blocks are different.

[0008] Preferably, the other end of the return spring is fixedly connected to a docking plug. A docking hole is formed on the surface of the rectangular block. An anti-slip sleeve is arranged on the inner wall of the docking hole. By arranging the docking plug and inserting it into the docking hole, the fixed clamping block can be quickly docked and assembled with the rectangular block. When disassembling, it can be directly pulled out, which simplifies the disassembly and replacement work of positioning the workpiece.

[0009] Preferably, a damping rotating shaft is provided at the bottom of the rectangular block, and the bottom of the damping rotating shaft is connected to the top of the support plate.

[0024] According to an embodiment of the present invention, a long and slender stator core winding jig is provided.

[0025] Embodiment 1;

[0026] As Figures 1-4As shown in the figure, the slender stator core winding fixture according to the embodiment of the present utility model includes an outer protection component 1 and a support plate 2. The outer protection component 1 and the support plate 2 are fixedly connected to each other. A placement groove 3 is provided at the center of the surface of the support plate 2. Positioning components 4 are arranged on both sides of the placement groove 3. The positioning component 4 includes a rectangular block 401. A return spring 403 is arranged on the surface of the rectangular block 401. The top end of the return spring 403 is fixedly connected to a fixed clamping block 404. The number of the fixed clamping blocks 404 is four groups, and they are arranged in a circumferential array on the outer wall of the rectangular block 401. The four groups of fixed clamping blocks 404 are designed in a "V" shape, and the sizes of the "V" - shaped openings of the four groups of fixed clamping blocks 404 are different.

[0027] In this embodiment, the other end of the return spring 403 is fixedly connected to a docking plug 405. A docking hole 402 is provided on the surface of the rectangular block 401. An anti - slip sleeve is arranged on the inner wall of the docking hole 402. By arranging the docking plug 405 and inserting it into the docking hole 402, the fixed clamping block 404 can be quickly docked and assembled with the rectangular block 401. When disassembling, it can be directly pulled out, which simplifies the disassembly, installation and replacement work of the positioning workpiece.

[0028] In this embodiment, a damping rotating shaft 406 is arranged at the bottom of the rectangular block 401. The bottom of the damping rotating shaft 406 is connected to the top of the support plate 2. The rectangular block 401 and the support plate 2 form a rotatable structure through the damping rotating shaft 406. By arranging the damping rotating shaft 406, the rectangular block 401 can be driven to rotate on the support plate 2, so as to quickly adjust and use fixed clamping blocks 404 of different sizes according to the size of the stator core workpiece during the stator winding process.

[0029] In this embodiment, the outer protection component 1 includes a box body 101. The top of the box body 101 is hinged with a cover plate 102 through a hinge. By arranging the outer protection component 1, after the winding fixture is used, it can be put into it, which can play a good protection role for it, and avoid the winding fixture from being worn due to external forces or the external environment when not in use.

[0030] In this embodiment, a support rod is fixedly connected to the bottom of the box body 101. The bottom of the support rod is fixedly connected to a bottom support block 104. The bottom area of the bottom support block 104 is larger than its top. By arranging the bottom support block 104 with a special shape, the contact area between the box body 101 and the ground is increased, and the placement stability of the box body 101 is increased. Because the winding fixture is connected to the outer protection component 1, the stability of the stator core winding process is also increased at the same time.

[0031] Embodiment Two;

[0032] On the basis of Embodiment One, the preferred embodiment of the slender stator core winding fixture provided by the present utility model is as Figures 1 to 4 shown:

[0033] In this embodiment, an anti-slip floor mat 105 is adhesively bonded to the bottom of the bottom support block 104. The anti-slip floor mat 105 is made of flexible rubber material. By providing the anti-slip floor mat 105, the placement stability of the box body 101 is further improved. Since it is made of rubber material, it can reduce the shaking during the wire winding process and further improve the stability of the wire winding process.

[0034] In this embodiment, a limiting hole is opened inside the box body 101, and a telescopic rod 103 is fixedly connected inside the limiting hole. The top of the telescopic rod 103 is connected to the bottom of the support plate 2. Holding handles are fixedly installed on both sides of the support plate 2. By providing the telescopic rod 103, the support plate 2 can be driven to lift and adjust the use position, facilitating the operation of workers of different heights. With the cooperation of the holding handles for auxiliary operation, people can conveniently pull out the wire winding jig from the box body 101 quickly.

[0035] In order to facilitate the understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0036] In actual application, when the wire winding jig needs to be used, open the cover plate 102, grab the holding handles on both sides of the support plate 2 and lift upwards. The support plate 2 will continuously rise under the action of the telescopic rod 103. After adjusting to the appropriate position, place the stator core into the placement groove 3, and then dial the fixed clamping block 404 backward. After the reset spring 403 contracts and deforms, the fixed clamping block 404 clamps and positions the stator core from both sides. Then, the stator core is wound by an external manipulator. Since the number of the fixed clamping blocks 404 is four groups and their sizes are different, they can be flexibly adjusted according to the size of the stator core workpiece placed by driving the rectangular block 401 to rotate through the damping rotating shaft 406, with strong adaptability. The fixed clamping block 404 is installed by inserting the docking plug 405 at the end of the reset spring 403 into the docking hole 402 on the surface of the rectangular block 401. The disassembly and assembly are convenient and can be quickly replaced, facilitating people's operation. The setting of the bottom support block 104 with a special shape increases the contact area between the box body 101 and the ground. With the anti-slip floor mat 105 at its bottom, the placement stability of the box body 101 is effectively increased. Because the wire winding jig is connected to the outer protection component 1, the stability of the stator core wire winding process is also increased simultaneously. After the wire winding work is completed, the wire winding jig is retracted into the box body 101 by the contraction of the telescopic rod 103. After covering the cover plate 102, a closed space is formed, so that the wire winding jig can be well protected, avoiding being knocked, scratched by external forces or worn due to the influence of the external environment when not in use.

[0037] In summary, by means of the above technical solution of the present utility model, through the provided positioning component 4, different-sized fixing blocks 404 can be quickly adjusted and used according to the size of the stator core workpiece during the winding process of the stator core, with strong applicability. At the same time, the fixing blocks 404 are convenient to disassemble and assemble, can be quickly replaced, and facilitate people's operations. Through the provided outer protection component 1, after the winding fixture is used, it is stored in the box body 101, which can play a good protective role, avoiding the winding fixture from being knocked, scratched or worn due to external forces or the influence of the external environment when not in use.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
