For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium.

[0020] In the description of this specification, the descriptions referring to terms such as "embodiment", "one embodiment", "some implementation manners", "exemplarily", and "one implementation manner" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or implementation manner are included in at least one embodiment or implementation manner of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or implementation manner. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or implementation manners in a suitable manner.

[0021] The terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. In this way, the features defined with "first" and "second" can explicitly or implicitly include at least one of such features.

[0022] An embodiment of the present invention provides a wire polishing and processing device, including: a machine tool 1; a plurality of inner polishing wheel assemblies 2 arranged circumferentially along the machine tool 1; a plurality of outer polishing wheel assemblies 3 arranged circumferentially along the machine tool 1. A plurality of outer polishing wheel assemblies 3 are all located on the periphery of a plurality of inner polishing wheel assemblies 2. The outer polishing wheel assemblies 3 and the inner polishing wheel assemblies 2 are arranged at intervals. The plurality of inner polishing wheel assemblies 2 and the plurality of outer polishing wheel assemblies 3 can rotate synchronously, and the rotation directions of adjacent inner polishing wheel assemblies 2 and outer polishing wheel assemblies 3 are opposite.

[0023] Specifically, Figure 1 and Figure 2 is a schematic top view of the machine tool 1, and Figure 1 and Figure 2 the arrows beside the wire 100 in represent the traveling direction of the wire 100, and the arrows in the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 represent the rotation directions of the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3.

[0024] In this alternative embodiment, in combination with Figure 1 and Figure 2 as shown, by arranging a plurality of inner polishing wheel assemblies 2 and outer polishing wheel assemblies 3 on the machine tool 1, the plurality of outer polishing wheel assemblies 3 are all located on the periphery of the plurality of inner polishing wheel assemblies 2, and the outer polishing wheel assemblies 3 and the inner polishing wheel assemblies 2 are arranged at intervals. In this way, the wire 100 can bypass between the inner polishing wheel assemblies 2 and the outer polishing wheel assemblies 3 multiple times in sequence, so that one side circumferential surface of the wire 100 can repeatedly pass through the plurality of inner polishing wheel assemblies 2, and the other side circumferential surface of the wire 100 can repeatedly pass through the plurality of outer polishing wheel assemblies 3, realizing a comprehensive and repeated polishing process of the circumferential surface of the wire 100, thereby improving the polishing quality. At the same time, the plurality of inner polishing wheel assemblies 2 and the plurality of outer polishing wheel assemblies 3 can rotate synchronously, and the rotation directions of adjacent inner polishing wheel assemblies 2 and outer polishing wheel assemblies 3 are opposite. As Figure 1 shown, the inner polishing wheel assembly 2 rotates counterclockwise, and the outer polishing wheel assembly 3 rotates clockwise. The relative movement directions between the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 and the wire 100 are opposite, increasing the relative speed between the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 and the wire 100, so that the cutting effect of the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 on the wire 100 is stronger, which helps to quickly remove a relatively thick oxide layer or a relatively rough surface. As Figure 2 shown, the inner polishing wheel assembly 2 rotates clockwise, and the outer polishing wheel assembly 3 rotates counterclockwise. At this time, the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 rotate along the traveling direction of the wire 100, making the relative movement between the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 and the wire 100 smoother, and being able to more evenly remove the minute unevenness on the surface of the wire 100, improving the surface finish of the wire 100. By intermittently changing the rotation directions of the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3, the polishing quality of the surface of the wire 100 can be comprehensively improved.

[0025] Furthermore, the plurality of inner polishing wheel assemblies 2 are evenly arranged on the first circular track, and the plurality of outer polishing wheel assemblies 3 are evenly arranged on the second circular track. The radius of the second circular track is greater than the radius of the first circular track, and the second circular track and the first circular track are concentric circles.

[0026] In this alternative embodiment, in combination with Figure 1 andFigure 2 As shown, the second annular track and the first annular track are set as concentric circles, and the radius of the second annular track is greater than that of the first annular track, so that all the outer polishing wheel assemblies 3 are located outside all the inner polishing wheel assemblies 2.

[0027] Optionally, the number of the inner polishing wheel assemblies 2 is one more than that of the outer polishing wheel assemblies 3.

[0028] In this optional embodiment, combined with Figure 1 and Figure 2 As shown, the number of the inner polishing wheel assemblies 2 is four, and the number of the outer polishing wheel assemblies 3 is three. In this way, the inner polishing wheel assembly 2 at the lower right corner and the inner polishing wheel assembly 2 at the lower left corner can serve as the feeding side and the discharging side of the wire 100. It should be noted that when the wire 100 is fed into the machine tool 1 or discharged from the machine tool 1, guide wheels can be arranged on the feeding path and the discharging path of the wire 100 to guide the wire 100.

[0029] Furthermore, the inner polishing wheel assembly 2 includes a first polishing wheel 21, a first sleeve 22, a first rotating shaft 23 and a first bearing 24.

The structural composition of the inner polishing wheel assembly 2 will be described below. A perforation for the first rotating shaft 23 to penetrate is provided on the machine tool 1, so that both ends of the first rotating shaft 23 extend out of the upper surface and the lower surface of the machine tool 1 respectively. The second polishing wheel 31 is detachably sleeved on the upper end of the first rotating shaft 23. The inner ring of the first bearing 24 is sleeved on the lower end of the first rotating shaft 23, and the first rotating shaft 23 can be installed on the lower surface of the machine tool 1 through a bearing seat. The first sleeve 22 is sleeved on the first rotating shaft 23 between the first bearing 24 and the lower surface of the machine tool 1. In this way, an installation space can be provided for the subsequent transmission assembly 4.

[0032] Further, the wire polishing device further includes a transmission assembly 4, and the transmission assembly 4 is disposed between adjacent inner polishing wheel assemblies 2 and outer polishing wheel assemblies 3, so that the rotation directions of adjacent inner polishing wheel assemblies 2 and outer polishing wheel assemblies 3 are opposite.

[0034] Further, a first spiral groove 222 is provided on the outer peripheral surface of the first sleeve 22.

A first clamping hole 221 is provided on the first spiral groove 222, and the first clamping hole 221 can also be integrally formed. A second spiral groove 322 is provided on the outer peripheral surface of the second sleeve 32. The second spiral groove 322 can be integrally formed on the outer peripheral surface of the second sleeve 32. A second clamping hole 321 is provided on the second spiral groove 322, and the second clamping hole 321 can also be integrally formed. Both ends of the first steel wire rope 41 are respectively connected to the corresponding first clamping hole 221 and second clamping hole 321, and the first steel wire rope 41 is respectively wound on the first spiral groove 222 and the second spiral groove 322. Both ends of the second steel wire rope 42 are respectively connected to the corresponding first clamping hole 221 and second clamping hole 321, and the first steel wire rope 41 is respectively wound on the first spiral groove 222 and the second spiral groove 322. Among them, the ends of the first steel wire rope 41 and the second steel wire rope 42 can be fixed with wire clips with slightly larger diameters and then clamped in the first clamping hole 221 and the second clamping hole 321. The first steel wire rope 41 and the second steel wire rope 42 are arranged one above the other. After the first steel wire rope 41 and the second steel wire rope 42 are wound around the first spiral groove 222 for several turns, they are wound on the second spiral groove 322. The winding methods of the first steel wire rope 41 and the second steel wire rope 42 are the same. The first sleeve 22 rotates clockwise, and the second sleeve 32 rotates counterclockwise, as Figure 2 shown, or the first sleeve 22 rotates counterclockwise, and the second sleeve 32 rotates clockwise, as Figure 1 shown. The states of the first steel wire rope 41 and the second steel wire rope 42 during rotation are: the first steel wire rope 41 takes in the rope, and the second steel wire rope 42 pays out the rope, or the first steel wire rope 41 pays out the rope, and the second steel wire rope 42 takes in the rope.
