Description

Technical Field

[0001] This utility model relates to the field of conductive slip ring technology, specifically an integrated conductive slip ring. Background Technology

[0002] In the processing of metal products such as copper tubes and copper busbars, a coiling mill is required. The coiling mill is connected to a station switching frame, such as... Figure 1 As shown, the upper part of the workstation switching frame has an upper rotating frame 100. The upper rotating frame 100 is equipped with 2-4 large arms 200 according to the number of subsequent workstations. Hanging rods 300 are vertically installed on the large arms 200. After the metal products are rolled into coils, they are wound onto the hanging rods 300. There are multiple motors on the workstation switching frame that correspond one-to-one with the subsequent workstations. In order to ensure the circuit connection of the motors, conductive slip rings 400 are installed on the upper rotating frame 100. However, in the prior art, the insulating plate 18 on which the carbon brush 22 is installed is connected to the upper rotating frame 100 or the large arms 200. When the metal products are wound onto the hanging rods 300, due to the excessive weight, the large arms 200 will bend downward and the upper rotating frame 100 will be tilted towards the intermediate product direction. This causes the carbon brush 22 to detach from the working unit 4 of the conductive slip ring 400 and become misaligned, resulting in poor carbon brush contact, jamming, displacement, and even short circuits and carbon brush breakage. Utility Model Content

[0003] The technical problem to be solved by this invention is to overcome the existing defects and provide an integrated conductive slip ring, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model discloses an integrated conductive slip ring. The technical solution includes a body with a body base and an upper base. The upper base is connected to the body base. Multiple working units are stacked on the body base, and each working unit has a conductive unit. An insulating layer separates adjacent conductive units. The system also includes an insulating plate with carbon brushes mounted on it. The carbon brushes slide in contact with the conductive units. The body is mounted on a lower base. Both the lower and upper bases are equipped with bearings, each bearing having an end cap. A connecting bracket is installed between two bearing end caps. The insulating plate is mounted on the connecting bracket. The conductive units on each working unit are conductive blocks, and there are multiple conductive blocks with insulating blocks between adjacent blocks. By mounting the insulating plate on the connecting bracket and connecting the connecting bracket to the conductive slip ring via the bearing end plate and bearings, the carbon brushes can be effectively prevented from disengaging from the conductive units due to the offset of the upper arm and upper rotating frame, ensuring stable circuit connection. Furthermore, the conductive slip ring is no longer subjected to downward gravity, thus improving its service life.

[0005] In a preferred embodiment of this invention, the connecting bracket connects to the insulating plate via a bracket plate. The bracket plate has a slotted connecting hole, and the insulating plate has a first bolt hole through which a connecting bolt passes. The connecting bolt, after passing through the connecting hole, engages with a connecting nut. The slotted connecting hole allows adjustment of the distance between the insulating plate and the working unit, ensuring stable and sufficient contact between the carbon brush and the conductive block.

[0006] As a preferred embodiment of this utility model, the insulating plate is provided with a fixing hole, which corresponds to the position of the working unit. It also includes a carbon brush holder, on which a fixing bolt is connected. The fixing bolt passes through the fixing hole and is connected with a fixing nut.

[0007] As a preferred embodiment of this utility model, both the conductive block and the insulating block are fan-shaped structures, and in each working unit, the conductive block and the insulating block are staggered. When the carbon brush is in contact with the insulating block, the electrical connection is cut off, and when the carbon brush is in contact with the conductive block, the circuit is connected.

[0008] In a preferred embodiment of this invention, the working unit includes an insulating base, the bottom plate of which is the insulating layer. Multiple receiving slots are formed on the insulating base, and an insulating block is located between adjacent receiving slots. A conductive block is located within each receiving slot. The insulating layer and the insulating block can be manufactured as a single unit, reducing costs.

[0009] As a preferred technical solution of this utility model, the stacked working units are covered with a pressure cover, and both the pressure cover and the working units are provided with through holes. An insulating sleeve is inserted into the through hole, and a locking bolt is in the insulating sleeve. The main body base is provided with a locking threaded hole, and the locking bolt is engaged in the locking threaded hole.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: By connecting the insulating plate for mounting the carbon brush holder to the conductive slip ring body through bearings and bearing end caps, this utility model ensures the stability and smoothness of the connection between the carbon brush and the conductive block. This ensures that the carbon brush rotates only under lateral pushing force, and the insulating plate is no longer warped due to the tilt of the boom and upper rotating frame, thus improving the service life of the carbon brush. Furthermore, in the working unit, the conductive blocks and insulating blocks are staggered. By designing appropriate dimensions for the conductive and insulating blocks according to production needs, the power supply to the rotary motor can be effectively and accurately controlled, ensuring smooth production.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 2 to 6As shown, this embodiment discloses the first implementation of the present invention. The technical solution adopted includes a main body base 2, on which an upper base 10 is connected. The upper base 10 is a tubular structure and is perpendicularly connected to the main body base 2. An insulating layer 3 and a working unit 4 are fitted on the upper base 10. The insulating layer 3 is made of epoxy resin. The insulating layer 3 and the working unit 4 are stacked alternately on top of the main body base 2, as shown. Figure 6 As shown, the working unit 4 includes a conductive block 7 and an insulating block 8. The conductive block 7 is a copper block, and the insulating block 8 is an epoxy resin block. Both are fan-shaped structures, which are staggered to form a complete ring. The stacked structure composed of the insulating layer 3 and the working unit 4 has insulating layers 3 at both ends. A pressure cap 6 is also provided above the uppermost insulating layer 3. In order to position the conductive block 7 and the insulating block 8, two through holes are opened on the insulating layer 3, the conductive block 7, the insulating block 8, and the pressure cap 6. An insulating sleeve 5 is inserted through the through holes. A locking threaded hole corresponding to the position of the insulating sleeve 5 is opened on the main body base 2. A locking bolt 25 is inserted into the insulating sleeve 5 and engaged in the locking threaded hole. The countersunk head of the locking bolt 25 presses the pressure cap 6.

[0022] The main body base 2 has a mounting hole 19 and also includes a lower base 1. The lower base 1 has a mounting threaded hole. A mounting bolt is passed through the mounting hole 19 and engaged in the mounting threaded hole to mount the conductive slip ring body onto the lower base 1. A lower bearing 13 is fitted onto the lower base 1, and an upper bearing 12 is mounted on the upper base 10. A second bearing end cap 11 and a first bearing end cap 9 are respectively mounted on the upper bearing 12 and the lower bearing 13. The inner ring of the lower bearing 13 is press-fitted with the lower base 1, the outer ring of the lower bearing 13 is press-fitted with the first bearing end cap 9, the inner ring of the upper bearing 12 is press-fitted with the upper base 10, and the outer ring of the upper bearing 12 is press-fitted with the second bearing end cap 11. The first bearing end cover 9 and the second bearing end cover 11 are connected by a C-shaped connecting bracket 15. The connecting bracket 15 is welded to the end face of the second bearing end cover 11 and is bolted to the mounting surface 14 of the first bearing end cover 9. There are four sets of connecting brackets 15, which are arranged in a ring array on the first bearing end cover 9 and the second bearing end cover 11. A bracket plate 17 is mounted on the connecting bracket 15. A transverse waist-shaped connecting hole 16 is opened on the bracket plate 17. An insulating plate 18 is connected to the bracket plate 17. A first bolt hole is opened at one end of the insulating plate 18, and a stamp-shaped fixing hole 21 is opened at the other end. A connecting bolt 24 is inserted into the first bolt hole. After the connecting bolt 24 passes through the connecting hole 16, it is locked with a connecting nut to fix the insulating plate 18 to the bracket plate 17. A carbon brush holder 20 is mounted on the insulating plate 18. A second bolt hole is provided on the carbon brush holder 20. After the fixing bolt 23 passes through the second bolt hole and the fixing hole 21, it is locked with a fixing nut. A carbon brush 22 is mounted on the carbon brush holder 20. The carbon brush 22 slides in contact with the outer curved surface of the conductive block 7 and the insulating block 8.

[0023] Working principle: The carbon brush 22 is electrically connected to the motor, and the connecting bracket 15 is connected to the upper rotating frame 100. When the upper rotating frame 100 rotates, it drives the connecting bracket 15 to drive the second bearing end cover 11, the first bearing end cover 9 and the carbon brush 22 to rotate. The carbon brush 22 connected to the motor corresponding to the working position is connected to the conductive block 7, and the motor is powered on and running. When the carbon brush 22 connected to the motor corresponding to the waiting position is connected to the insulating block 8, the motor is powered off and in standby mode. Due to the support of the bearing, the connecting bracket 15 and the insulating plate 18 will not warp, thereby ensuring stable contact between the carbon brush 22 and the working unit 4 and extending the service life of the carbon brush 22. Example 2

[0024] like Figure 7 , Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the insulating layer 3 and the insulating block 8 are integrally formed to form the insulating base 41, and there is a receiving groove 42 between two adjacent insulating blocks 8, in which the conductive block 7 is installed.
