[0002] A rotary conductive device is often used in the rotary welding process. The rotary conductive device realizes continuous rotary power supply and signal transmission: it allows the equipment to stably transmit power and signals when rotating 360 degrees, ensuring transmission stability.

[0003] However, the existing rotary conductive device has the following disadvantages: First, mechanical wear: The conductive ring will produce friction and wear during long-term use. It is necessary to replace the conductive ring and other wearing parts regularly, otherwise it will affect the conductive performance and even cause failure.

[0004] Second, the cost is high: the existing conductive rings have a complex structure, including precision conductive rings, brushes, bearings and other components, and have high requirements on materials, processing accuracy and assembly technology, so the manufacturing cost is high, resulting in an increase in equipment procurement costs.

[0005] Third, high maintenance requirements: To ensure performance and life, regular inspection, cleaning, lubrication and replacement of wearing parts and other maintenance work are required, and high professional skills are required for maintenance personnel, which increases the cost and difficulty of equipment maintenance.

[0006] The present invention designs a rotary conductive device for a roller sleeve welding positioner to solve the above problems. Summary of the invention

[0007] Based on this, it is necessary to provide a roller sleeve welding positioner rotary conductive device to address the problems existing in the current rotary conductive device. By designing an adjustable arc pressure plate, after the conductive shell and the arc pressure plate are damaged due to friction, the gear ring will squeeze the mounting slider through the first extrusion surface and the second extrusion surface, so that the arc pressure plate installed on the mounting slider can automatically adhere to the inner wall surface of the conductive shell. There is no need for maintenance and replacement of the ring, and the service life is relatively long. In addition, the rotary conductive device designed by the present invention has a simple structure, low cost, and is easy to maintain.

[0008] The above purpose is achieved through the following technical solutions: A rotary conductive device for a roller sleeve welding positioner, comprising: The conductive rod is rotatably mounted on a fixed disk of a fixed sleeve.

[0009] A rotary conductive component is fixedly mounted on a mounting base; the rotary conductive component comprises a conductive shell, a gear ring, a mounting ring, a mounting slider, and an arc-shaped pressure plate, wherein the conductive shell is fixedly mounted on the back of the mounting base, a mounting ring is rotatably mounted inside the conductive shell, a plurality of mounting sliders are circumferentially uniformly mounted on the mounting ring for sliding, and an arc-shaped pressure plate is fixedly mounted on one end of each mounting slider close to the inner wall of the conductive ring; the arc-shaped pressure plate cooperates with the inner wall of the wire shell; the arc-shaped pressure plate and the mounting slider are both made of conductive materials; a gear ring is detachably mounted on the conductive rod, and the gear ring is made of conductive material; the teeth on the gear ring correspond one-to-one with the mounting slider mounted on the mounting ring and are in extrusion contact and fit.

[0010] In one of the embodiments, a connecting rod is fixedly installed on the outer circular surface of the conductive shell, an L-shaped fixing plate is fixedly installed on the lower end of the connecting rod, and the fixing plate is fixedly installed on the back of the mounting base by bolts; the connecting rod and the fixing plate are both made of non-conductive materials.

[0011] In one of the embodiments, a power connection plate is fixedly mounted on the outer circumferential surface of the conductive shell, and the external conductive wire is connected to the power connection plate by bolts.

[0012] In one of the embodiments, an annular guide groove is formed on the inner wall of the conductive shell, an annular guide block is fixedly mounted on one side of the mounting ring, and the mounting ring is rotatably mounted in the conductive shell through the cooperation between the annular guide block and the annular guide groove.

[0014] In one embodiment, the end of the mounting slider that is not fixed with the arc pressure plate has a second extrusion surface, and the teeth of the gear ring have a first extrusion surface; the first extrusion surface on the gear ring is in contact and extrusion fit with the second extrusion surface on the corresponding mounting slider.

[0015] In one embodiment, the inner walls of the arc-shaped pressure plate and the conductive ring are provided with a wear-resistant layer.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0033] like Figure 1 -like Fig.10 As shown, a rotary conductive device of a roller sleeve welding positioner comprises a conductive rod 8, which is rotatably mounted on a fixed plate 4 of a fixed sleeve 5; a rotary conductive component 9, which is fixedly mounted on a mounting base 3; Figure 4 , 5 6, the rotary conductive component 9 includes a conductive shell 904, a gear ring 907, a mounting ring 906, a mounting slider 909, and an arc-shaped pressing plate 908, wherein the conductive shell 904 is fixedly mounted on the back of the mounting base 3, and the mounting ring 906 is rotatably mounted in the conductive shell 904, as shown in FIG. Figure 8As shown, a plurality of mounting slide blocks 909 are uniformly mounted on the mounting ring 906 for sliding movement in the circumferential direction, and an arc-shaped pressing plate 908 is fixedly mounted on one end of each mounting slide block 909 close to the inner wall surface of the conductive ring; the arc-shaped pressing plate 908 cooperates with the inner wall surface of the wire housing; the arc-shaped pressing plate 908 and the mounting slide block 909 are both made of conductive materials; Figure 7 As shown, a toothed ring 907 is detachably mounted on the conductive rod 8, and the toothed ring 907 is made of conductive material; the teeth on the toothed ring 907 correspond one-to-one with the mounting slider 909 mounted on the mounting ring 906 and are in extrusion contact fit.

[0034] like Figure 1 , 2 As shown in Figure 3, a main control box 1 and a mounting base 3 are fixedly installed on the upper side of the base, and a fixed disk 4 is rotatably installed on the front side of the mounting base 3; a power component capable of driving the fixed disk 4 to rotate circumferentially is installed in the mounting base 3; a fixed square shaft 6 is fixedly installed on the front side of the mounting base 3, and a conductive rod 8 is installed in the fixed square shaft 6; a processed sleeve 5 is installed on the fixed disk 4 through a fixing component 7; a welding device 2 is installed on one side of the main control box 1, and the welding device 2 is located obliquely above the sleeve 5.

[0035] In the present invention, the conductive shell 904 is fixed on the back of the mounting base 3 and is relatively stationary. When the fixed disk 4 is driven to rotate by the power component installed in the mounting base 3, the fixed disk 4 will drive the fixed square shaft 6, the conductive rod 8, the fixed component 7 and the processed sleeve 5 to rotate together; the rotation of the conductive rod 8 drives the gear ring 907 to rotate, and the rotation of the gear ring 907 will first squeeze the mounting slider 909, so that the mounting slider 909 slides toward the inner wall of the conductive shell 904, and the sliding of the mounting slider 909 drives the mounting The arc-shaped pressing plate 908 on it slides, so that the arc-shaped pressing plate 908 is tightly pressed against the inner wall of the conductive shell 904. When the arc-shaped pressing plate 908 is in close contact with the inner wall of the conductive shell 904, the rotation of the gear ring 907 will drive the mounting slider 909 to rotate circumferentially together, and the rotation of the mounting slider 909 will drive the arc-shaped pressing plate 908 to rotate circumferentially relative to the conductive shell 904; during the rotation process, the arc-shaped pressing plate 908 will be close to the inner wall of the conductive shell 904, and the conductive shell 904 will pass electricity through the arc-shaped pressing plate 908 after being energized. The pressing plate 908 and the mounting slide block 909 transmit electricity to the gear ring 907, and the gear ring 907 transmits electricity to the conductive rod 8, and the conductive rod 8 transmits electricity to the processed sleeve 5, ensuring that the sleeve 5 can be smoothly welded by the welding device 2; as for the electrical connection between the conductive rod 8 and the sleeve 5, it is the prior art; when the present invention is used, the arc-shaped pressing plate 908 can be controlled to be pressed tightly against the inner wall of the conductive shell 904 before power is applied, so as to prevent the arc-shaped pressing plate 908 from being in contact with the inner wall of the conductive shell 904. An arc is generated when they touch, which affects the conductive effect of the conductive shell 904 and the arc pressure plate 908. In addition, during the circumferential rotation of the arc pressure plate 908, the present invention will always be subjected to the extrusion pressure of the gear ring 907 toward the inner wall of the guide shell, and the extrusion pressure can ensure that the arc pressure plate 908 and the conductive shell 904 have a high contact, thereby ensuring the conductive effect. After being relatively stable, the gear ring 907 and the mounting slider 909 are in a relatively static state, and the wear is almost zero, so there will be no power outage between the two.

[0036] In the present invention, because there are multiple arc-shaped pressure plates 908, even if one of them is disconnected from the inner wall of the conductive shell 904, there are still other arc-shaped pressure plates 908 in close contact with the conductive shell 904, and the probability of all being disconnected is relatively small, so in this case, power outages will not easily occur; if traditional rings are matched, when the two rings are misaligned, it is possible to cause power outages.

[0037] The present invention designs an adjustable arc pressure plate 908. After the conductive shell 904 and the arc pressure plate 908 are damaged due to friction, the gear ring 907 will squeeze the mounting slider 909 through the first extrusion surface 910 and the second extrusion surface 911, so that the arc pressure plate 908 installed on the mounting slider 909 can automatically adhere to the inner wall surface of the conductive shell 904, without the need for maintenance and replacement of the ring, and has a relatively long service life. In addition, the rotary conductive device designed by the present invention has a simple structure, low cost, and is easy to maintain.

[0038] In a further embodiment, Figure 4 , 5 As shown, a connecting rod 903 is fixedly installed on the outer circumferential surface of the conductive shell 904, and an L-shaped fixing plate 902 is fixedly installed on the lower end of the connecting rod 903. The fixing plate 902 is fixedly installed on the back of the mounting base 3 by bolts; the connecting rod 903 and the fixing plate 902 are both made of non-conductive materials.

[0039] In a further embodiment, Fig. 9 As shown, a power connection piece 901 is fixedly mounted on the outer circumferential surface of the conductive shell 904 , and the external conductive wire is connected to the power connection piece 901 by bolts.

[0040] In a further embodiment, Figure 8 , 9 As shown in FIG. 10 , an annular guide groove 913 is formed on the inner wall of the conductive shell 904 , and an annular guide block 912 is fixedly mounted on one side of the mounting ring 906 . The mounting ring 906 is rotatably mounted in the conductive shell 904 through the cooperation between the annular guide block 912 and the annular guide groove 913 .

[0041] In a further embodiment, the mounting ring 906 is made of conductive material, an annular guide groove 913 is opened on the inner wall of the conductive shell 904, an annular guide block 912 is fixedly installed on one side of the mounting ring 906, and the mounting ring 906 is rotatably installed in the conductive shell 904 through the cooperation between the annular guide block 912 and the annular guide groove 913.

[0042] During use, even if the arc pressure plate 908 is disconnected from the conductive shell 904, the cooperation between the annular guide block 912 and the annular guide groove 913 can enable the conductive shell 904 to transfer electricity to the gear ring 907 through the mounting ring 906, and then to the conductive rod 8; that is, by designing the mounting ring 906 to be a conductive material, an additional layer of protection can be provided to prevent the conductive rod 8 from being powered off.

[0043] In a further embodiment, Figure 7 , 8 As shown, the end of the mounting slider 909 on which the arc pressure plate 908 is not fixed has a second extrusion surface 911, and the teeth of the gear ring 907 have a first extrusion surface 910; the first extrusion surface 910 on the gear ring 907 is in contact and extruded with the second extrusion surface 911 on the corresponding mounting slider 909.

[0044] In a further embodiment, the arc-shaped pressure plate 908 and the inner wall of the conductive ring have a wear-resistant layer.

[0045] In a further embodiment, Figure 7 As shown, the conductive rod 8 and the gear ring 907 are connected via a keyway and a key transmission.

[0046] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
