Description

Technical Field

[0001] This utility model relates to the field of brush plate technology, and more specifically, to a durable welding machine brush plate. Background Technology

[0002] Chinese Utility Model Patent Application No. CN202122603919.8 discloses a long-life rotating brush plate, comprising: a brush plate body, the brush plate body being circular, a long brush body fixedly installed at the inner end of the brush plate body, a short brush body disposed on the right side of the long brush body, the right end of the short brush body being fixedly installed at the inner end of the brush plate body, a first mounting hole, the first mounting hole being opened at the left end of the brush plate body, a friction particle being fixedly installed at the inner end of the first mounting hole, and a first heat dissipation hole, the first heat dissipation hole being opened at the left end of the long brush body, the first heat dissipation hole being located on the right side of the first mounting hole. This long-life rotating brush plate is designed and manufactured using an isotropic curve, and multi-line friction is applied to the rotating ring during rotation, increasing the lifespan of the rotating connector by 3-5 times. It solves the problem of the influence of human factors on the rotation angle, enhances heat dissipation, increases the friction of the mounting part, and makes the installation more stable.

[0003] The aforementioned patent increases the service life of the rotary connector by providing a long brush body and a short brush body on the inner circumference of the brush body, which causes multi-line friction on the rotating ring during rotation. However, the brush body will wear down during the friction process. After a certain period of wear, the rotating ring and the brush body will have poor contact, resulting in welding abnormalities and no current in the welding machine.

[0004] Therefore, we have made improvements to this and proposed a durable welding machine brush plate. Utility Model Content

[0005] The purpose of this invention is to address the issue that the brush body will wear down during the friction process, and after a certain period of wear, the rotating ring will not make good contact with the brush body, which will lead to abnormal welding and no current in the welding machine.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A durable welding machine brush plate to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] The brush body includes a brush plate body. Both sides of the inner ring of the brush plate body are slidably fitted with elastic arc-shaped brush bodies. The brush plate body has multiple mounting holes on the side near the outer ring and multiple heat dissipation holes on the side near the inner ring. Each of the two elastic arc-shaped brush bodies is equipped with a connecting block on one side. At least one spring is installed on one side of the connecting block. A moving block is installed on the other end of the spring. A pressure adjustment component is provided between the two moving blocks and the interior of the brush plate body.

[0010] Friction occurs through the contact between the elastic arc-shaped brush bodies on both sides of the inner diameter of the brush plate and the rotating ring. The elastic arc-shaped brush bodies on both sides are always electrically connected to the brush plate body through the connecting blocks. The moving blocks on both sides are positioned by the pressure adjustment component. When the elastic arc-shaped brush bodies on both sides rub and wear, they will move towards the central axis by the action of the spring, ensuring that the elastic arc-shaped brush bodies on both sides are always in contact with the rotating ring for friction.

[0011] As a preferred embodiment of the durable welding machine brush plate provided by this utility model, the elastic arc-shaped brush body, the connecting block and the brush plate body are all electrically connected. Multiple friction particles are installed on the inner periphery of the mounting hole. An annular groove is opened inside the brush plate body. First limiting grooves are opened on both the upper and lower sides of the annular groove.

[0012] As a preferred embodiment of the durable welding machine brush plate provided by this utility model, a second limiting groove is provided on the right side of the annular groove, and a threaded hole is provided on one side wall of the annular groove. The central axis of the threaded hole and the transverse axis of the second limiting groove are located on the same horizontal plane.

[0013] In a preferred embodiment of the durable welding machine brush plate provided by this utility model, the upper and lower sides of the connecting block are equipped with first limiting blocks, and the upper and lower sides of the moving block are equipped with second limiting blocks. The first limiting blocks and the second limiting blocks are slidably engaged in the first limiting groove.

[0014] As a preferred embodiment of the durable welding machine brush plate provided by this utility model, the pressure regulating component includes a movable frame that slides in an annular groove, and third limiting blocks are installed on both the upper and lower sides of the movable frame. The third limiting blocks slide in a second limiting groove, and two connecting frames are provided between the movable frame and the movable blocks on the opposite sides.

[0015] As a preferred embodiment of the durable welding machine brush plate provided by this utility model, a first connecting post is installed on one side of each of the two moving blocks, and a second connecting post is installed on the opposite sides of the moving frame. A connecting groove is opened on the opposite sides of the connecting frame. The first connecting post is rotatably engaged in one of the connecting grooves, and the second connecting post is rotatably engaged in the other connecting groove.

[0016] In a preferred embodiment of the durable welding machine brush plate provided by this utility model, a first threaded rod is rotatably fitted on one side of the movable frame, and the first threaded rod is threadedly fitted in a threaded hole.

[0017] In a preferred embodiment of the durable welding machine brush plate provided by this utility model, a threaded rod is rotatably fitted on one side of the movable frame, and the threaded rod is threaded into a threaded hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the elastic arc-shaped brushes on both sides of the inner diameter of the brush body rub against the rotating ring. The elastic arc-shaped brushes on both sides are always electrically connected to the brush body through the connecting blocks. The moving blocks on both sides are positioned by the pressure adjustment component. When the elastic arc-shaped brushes on both sides wear due to friction, they will move towards the central axis through the action of the spring, ensuring that the elastic arc-shaped brushes on both sides are always in contact with the rotating ring for friction. This reduces the possibility of poor contact between the rotating ring and the brush body after a certain period of wear, which can lead to welding abnormalities and no current in the welding machine.

In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0031] As described in the background art, the brush body will be worn during the friction process. When the contact between the rotating ring and the brush body becomes poor after a certain period of wear, abnormal welding and no current situation will occur in the electric welding machine.

[0032] To solve this technical problem, this utility model provides a durable welding machine brush plate.

[0033] For details, please refer to Figure 1-4 The durable welding machine brush plate specifically includes: a brush plate body 1, with elastic arc-shaped brush bodies 2 slidingly fitted on both sides of the inner ring of the brush plate body 1, multiple mounting holes 3 on the side of the brush plate body 1 near the outer ring, multiple heat dissipation holes 4 on the side of the brush plate body 1 near the inner ring, a connecting block 7 on one side of each of the two elastic arc-shaped brush bodies 2, at least one spring 8 on one side of the connecting block 7, a moving block 9 on the other end of the spring 8, and a pressure adjustment component between the two moving blocks 9 and the interior of the brush plate body 1.

[0034] Friction occurs between the elastic arc-shaped brush bodies 2 on both sides of the inner diameter of the brush body 1 and the rotating ring. The elastic arc-shaped brush bodies 2 on both sides are always electrically connected to the brush body 1 through the connecting block 7. The moving blocks 9 on both sides are positioned by the pressure adjustment component. When the elastic arc-shaped brush bodies 2 on both sides rub and wear, they will move towards the central axis by the force of the spring 8 to ensure that the elastic arc-shaped brush bodies 2 on both sides are always in contact with the rotating ring and rub against it. This reduces the occurrence of wear. After a certain period of time, poor contact between the rotating ring and the brush body will occur, resulting in welding abnormalities and no current in the welding machine.

[0038] Example 1

[0039] Please refer to Figure 1-4A durable welding machine brush plate includes: a brush plate body 1, with elastic arc-shaped brush bodies 2 slidably fitted on both sides of the inner ring of the brush plate body 1; multiple mounting holes 3 are provided on the side of the brush plate body 1 near the outer ring; multiple heat dissipation holes 4 are provided on the side of the brush plate body 1 near the inner ring; connecting blocks 7 are installed on one side of each of the two elastic arc-shaped brush bodies 2; at least one spring 8 is installed on one side of the connecting block 7; a moving block 9 is installed on the other end of the spring 8; and a pressure regulating component is provided between the two moving blocks 9 and the interior of the brush plate body 1. The elastic arc-shaped brush bodies 2, connecting blocks 7, and brush plate body 1 are electrically connected. Multiple friction particles 6 are installed on the inner periphery of the mounting holes 3. An annular groove 5 is provided inside the brush plate body 1; first limiting grooves 14 are provided on both the upper and lower sides of the annular groove 5; a second limiting groove 16 is provided on the right side of the annular groove 5; and a threaded hole 12 is provided on one side wall of the annular groove 5, with the central axis of the threaded hole 12 and the transverse axis of the second limiting groove 16 located on the same horizontal plane. The connecting block 7 is equipped with a first limiting block 15 on both the upper and lower sides, and the moving block 9 is equipped with a second limiting block 17 on both the upper and lower sides. The first limiting block 15 and the second limiting block 17 are slidably engaged in the first limiting groove 14.

[0040] Implementation process: By opening multiple heat dissipation holes 4 on the side of the brush body 1 near the inner ring, the heat generated by the elastic arc-shaped brush body 2 during friction can be dissipated faster. The elastic arc-shaped brush body 2 on both sides of the inner diameter of the brush body 1 comes into contact with the rotating ring and rubs. After wear occurs due to friction, it will move towards the central axis by the force of the spring 8, ensuring that the elastic arc-shaped brush body 2 on both sides is always in contact with the rotating ring and continues to rub.

[0041] Benefits of implementation: By setting up an elastic arc-shaped brush body 2 that can move elastically, the service life of the brush body 1 is improved.

[0042] Example 2

[0043] The pressure regulating assembly includes a movable frame 10 that slides within an annular groove 5. Third limiting blocks 22 are mounted on both the upper and lower sides of the movable frame 10, and these third limiting blocks 22 slide within second limiting grooves 16. Two connecting frames 11 are provided between the movable frame 10 and the movable blocks 9 on opposite sides. A first connecting post 18 is mounted on one side of each of the two movable blocks 9, and a second connecting post 20 is mounted on opposite sides of the movable frame 10. Connecting grooves 19 are formed on opposite sides of each connecting frame 11. The first connecting post 18 rotatably engages within one connecting groove 19, and the second connecting post 20 rotatably engages within the other connecting groove 19. A threaded rod 13 rotatably engages on one side of the movable frame 10, and the threaded rod 13 is threaded into a threaded hole 12. One end of the threaded rod 13 has an "I"-shaped groove 21.

[0044] Implementation process: The threaded rod 13 can be rotated using a flathead screwdriver. The threaded rod 13 is threaded into the threaded hole 12, which allows the movable frame 10 to move within the annular groove 5. Within the sliding annular groove 5, the connecting frames 11 on both sides can drive the movable blocks 9 on both sides to slide towards the axis of the brush body 1, thereby squeezing the spring 8 and the connecting block 7. Rotating the threaded rod 13 in the opposite direction can loosen it. Improper adjustment of the existing brush contact pressure can also lead to increased brush wear. Therefore, the pressure of the elastic arc-shaped brush body 2 in contact with the rotating ring can be adjusted.

[0045] Benefits of implementation: The pressure of the adjustable elastic arc-shaped brush body 2 in contact with the rotating ring is increased, thereby increasing the service life of the adjustable elastic arc-shaped brush body 2.

[0046] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
