Technical Field

[0001] This utility model relates to the technical field, and in particular to an adjustable electromagnetic coil winding pivot and a winding device. Background Technology

[0002] When manufacturing electromagnetic brakes, coils of different diameters need to be manufactured according to the different sizes of the electromagnetic brakes. Currently, the coils are mainly wound onto winding hubs using a winding machine, and then the coils are removed and installed inside the electromagnetic brake. As mentioned above, since different electromagnetic coils require different coil diameters, different diameter coil winding hubs need to be provided during manufacturing. This results in the need to store a large number of winding hubs of different models. On the one hand, this occupies storage space and requires frequent replacement of winding hubs; on the other hand, it increases costs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable electromagnetic coil winding pivot and a winder. The adjustable electromagnetic coil winding pivot can quickly adjust its diameter to suit the manufacture of electromagnetic coils of different diameters.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] In a first aspect, this application discloses an adjustable electromagnetic coil winding pivot, comprising: a first chuck and a second chuck disposed opposite to each other, with a space defined between the first chuck and the second chuck, and a plurality of sector blocks disposed within the space, the sector blocks being sequentially spliced ​​together along the circumference to form a disk; a connecting member is provided between the first chuck and the second chuck, the connecting member causing the disk surfaces pressed by the first chuck and the second chuck to be tightly attached to the disk surface of the disk.

[0006] Its beneficial effect is that the sector-shaped block positioned between the first and second chucks can be adjusted in position according to actual needs to form disks of different diameters. This allows for the winding of coils of different diameters during the fabrication of electromagnetic coils to accommodate electromagnetic brakes of different sizes. Of course, the sector-shaped block can be fixed to the first and second chucks in different ways, such as by simply pressing it together or by using bolts.

[0007] Furthermore, the first chuck has one or more first through holes at its center, and the second chuck has second through holes corresponding to the number and position of the first through holes; the disk defines a third through hole at its center, and the projections of the first and second through holes are located within the projection range of the third through hole in the thickness direction of the disk; the connector is a bolt, and the bolt passes through the first, second, and third through holes.

[0009] Furthermore, the positioning hole group includes a first hole group and a second hole group; the circumferential diameter of the first hole group is smaller than the circumferential diameter of the second hole group; when the first hole group is paired with each of the corresponding positioning holes, each of the sector blocks is in close contact with each other.

[0010] Furthermore, the first chuck is provided with a plurality of guide grooves extending from the circumferential edge of the first chuck toward the center of the first chuck; each of the sector blocks extends a protrusion along the thickness direction toward one side wall of the first chuck, and the periphery of the protrusion fits against the inner side wall of the guide groove.

[0011] Furthermore, each of the sector blocks is provided with a protrusion, which is located on one side of the straight edge of the sector surface of the sector block.

[0012] Furthermore, it also includes a collar, which includes a first C-shaped ring and a second C-shaped ring. The open ends of the first C-shaped ring and the second C-shaped ring are matched to form a circular ring structure.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1-6 This invention discloses an adjustable electromagnetic coil winding pivot 100 and a winding device.

[0030] refer to Figure 1 and Figure 2 According to an embodiment of this application, an adjustable electromagnetic coil winding pivot 100 includes a first chuck 110 and a second chuck 120 disposed opposite to each other. A space is defined between the first chuck 110 and the second chuck 120, and a plurality of sector-shaped blocks 130 are disposed within the space. The sector-shaped blocks 130 are sequentially spliced ​​along the circumference to form a disk. A bolt (not shown in the figure) passes through the first chuck 110 and the second chuck 120 to press the disk surfaces of the first chuck 110 and the second chuck 120 tightly against the two sides of the disk. In use, an electromagnetic coil can be wound onto the disk formed by the splicing of the aforementioned sector-shaped blocks 130.

[0031] Understandably, the sector block 130, positioned between the first chuck 110 and the second chuck 120, can be adjusted in position according to actual needs to form disks of different diameters. This allows for the winding of coils of different diameters during the fabrication of electromagnetic coils to accommodate electromagnetic brakes of different sizes. Of course, the sector block 130 can be fixed to the first chuck 110 and the second chuck 120 using different fixing methods, such as by simply clamping it in place, or by using bolts.

[0032] Specifically, the first chuck 110 has three first through holes 111 at its center, and the corresponding second chuck 120 has three second through holes 121. The positions of the first through holes 111 and the second through holes 121 correspond to each other for the passage of the aforementioned bolts. Furthermore, as... Figure 3 As shown, the narrow sides of each sector block 130 are formed into an arc shape, and each sector block 130 defines a third through hole 11 at the center of the aforementioned disk. In the thickness direction of the disk, the projections of the first through hole 111 and the second through hole 121 are located within the projection range of the third through hole 11, so as to ensure that the bolt can pass through the third through hole 11 and simultaneously pass through the first through hole 111 and the second through hole 121, thereby connecting the first chuck 110 and the second chuck, and pressing and fixing the first chuck 110, the second chuck and the disk by the nut and bolt cap of the bolt.

[0033] like Figure 1 and Figure 2 The first chuck 110 and the second chuck are constructed with a plurality of positioning holes 12, forming multiple sets of positioning holes 12 arranged circumferentially with different diameters on the first chuck 110 or the second chuck. (Reference) Figure 3 Each of the sector blocks 130 is provided with a fixing hole 132 corresponding to the positioning hole 12. In this way, each positioning hole 12 in each group of positioning holes 12 with a circumferential diameter can be set with a corresponding sector block 130, so that after each sector block 130 is fixed to the corresponding positioning hole 12, a disk with a fixed diameter is formed; that is, the user can match the fixing hole 132 with different groups of positioning holes 12 according to their needs, so as to be suitable for manufacturing coils of different diameters.

[0034] It is understandable that the position of the positioning hole 12 is fixed. When the user adjusts the position of the sector block 130, the position of the aforementioned positioning hole 12 can be preset according to the model of the electromagnetic coil produced. Then the user can quickly position the sector block 130 by matching the position of the positioning hole 12 with the position of the fixed hole 132, so that the disk forms the corresponding circumferential diameter.

[0035] For example, the positioning hole group 12 includes a first hole group and a second hole group; the circumferential diameter of the first hole group is smaller than the circumferential diameter of the second hole group; reference Figure 1 and Figure 2As shown, when the first group of holes is paired with the corresponding positioning holes 12, the sector blocks 130 are in close contact with each other. At this time, the arc-shaped surfaces of the sector blocks 130 away from the third through hole 11 are continuously engaged, and the electromagnetic coil is wound around and closely attached to the continuous annular surface, thus obtaining a coil of the corresponding diameter. Of course, those skilled in the art can conceive of three or more groups of coils based on the two groups of positioning holes 12 disclosed in this application, but details are not elaborated here.

[0036] To facilitate user adjustment of the positions of each sector block 130, in some embodiments, the first chuck 110 is provided with a plurality of guide grooves 112, which extend from the circumferential edge of the first chuck 110 toward the center of the first chuck 110. (See also...) Figure 1 Understandably, each of the sector blocks 130 extends a protrusion 131 along its thickness direction toward one side wall of the first chuck 110, and the periphery of the protrusion 131 fits against the inner side wall of the guide groove 112. Specifically, the protrusion 131 has a cross-section in which one side of the rectangle is set as an arc, and this arc segment mates with the arc segment at the bottom of the groove in the guide groove 112.

[0037] As mentioned earlier, the sector block 130 is located within the space defined by the first chuck 110 and the second chuck, making it difficult to operate when adjusting the disc diameter. In this embodiment, the user can adjust the diameter by moving the protrusion 131 located in the guide groove 112. The protrusion 131 can protrude from the disc surface of the first chuck 110 to facilitate adjustment. This can bring at least two benefits: first, the user can quickly and conveniently adjust the position of the sector block 130 through the protrusion 131; second, through the guiding action of the guide groove 112, the sector block 130 can be accurately positioned along a predetermined trajectory to the corresponding positioning hole 12.

[0038] For details, please refer to the following: Figure 4 As shown, each of the sector blocks 130 is provided with a protrusion 131, which is located on one side of the straight edge in the sector surface of the sector block 130, and each protrusion 131 is correspondingly provided in a guide groove 112.

[0039] Furthermore, since the shape of the sector blocks 130 remains unchanged, after each sector block 130 switches from the position of the aforementioned first positioning hole group 12 (where all sector blocks 130 are closely attached) to a position where they are far apart from each other, that is, after moving along the guide groove 112 in a direction away from the third through hole 11, there will be a certain gap between each sector block 130. This will cause the coil wound on it to become taut in the gap area between two adjacent sector blocks 130, and the actual diameter of the coil wound on each sector block 130 will be slightly smaller than the preset diameter.

[0040] Therefore, in some embodiments, the winding pivot 100 further includes a collar 140, as referenced. Figure 5 and Figure 6 As shown, the collar 140 includes a first C-shaped ring 141 and a second C-shaped ring 142. The open ends of the first C-shaped ring 141 and the second C-shaped ring 142 mate to form a circular structure. Furthermore, when the fixing hole 132 mates with the positioning hole 12 of the second hole group, the arc surface of each of the sector blocks 130 away from the third through hole 11 fits against the inner wall of the collar 140. In this way, the collar 140 located on the outer periphery can be used to wind a coil to manufacture a coil of the corresponding diameter. Of course, the circumference after increasing the thickness of the collar 140 (i.e., increasing the diameter) should be the predetermined circumference diameter required for the electromagnetic coil.

[0041] More specifically, the first C-ring 141 and the second C-ring 142 are constructed as magnets at least at their openings, and the magnetic poles of the first C-ring 141 and the second C-ring 142 are opposite. During use, the user can quickly position the sector block 130 into the second positioning hole set 12, and then magnetically attract the first C-ring 141 and the second C-ring 142 to adjust the diameter. The operation is quick and convenient.

[0042] A winding device according to an embodiment of this application includes: a drive unit and an electromagnetic coil winding pivot 100 as described in the foregoing embodiments. The drive unit is provided with an output shaft; the center of the electromagnetic coil winding pivot 100 is connected to the output shaft. The output shaft drives the winding pivot 100 to wind copper wire into a coil.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
