[0002] Abrasive brushes are used for grinding and polishing instruments, meters and mechanical parts to improve their accuracy, finish, rust removal and corrosion resistance.

[0003] In the copper processing industry, the grinding machines of the cleaning lines mostly use double-supported brush roller devices to achieve stable operation. The existing brush roller devices install the brush roller, shaft, and bearing seat on the inner and outer disc seats, and are fixed by fixed pull rods to form an integral mechanism.

[0004] According to the grinding brush double back roller cantilever device disclosed in the patent No. CN213616028U, the device reduces the overall manufacturing cost of the equipment and improves the grinding quality; it is more convenient to replace the grinding brush and the back roller; the overall bearing seat structure is easier to manufacture and assemble, and has higher precision. However, when replacing the grinding brush in actual application, it is first necessary to remove the outer disc and then replace the grinding brush. Disassembly of the device is likely to cause damage to the device, and the grinding device used for copper processing is generally large in size, so the size of the grinding brush device used is also relatively large, so it is more time-consuming and laborious to replace the grinding brush; for this reason, we provide a copper processing grinding brush device to solve the above problems.

[0023] As described in the background technology, in actual applications, the outer disc needs to be removed and replaced, which is time-consuming and labor-intensive. For this reason, this embodiment provides a copper processing grinding brush device, which can make it more convenient and quick for workers to replace the grinding brush.

[0025] See also Figures 1 to 4 Because the grinding brush body 3 is heavy, the outer disc frame 1 needs to be made of a material with higher hardness, which can prevent the outer disc frame 1 from breaking due to being unable to bear the weight of the device, and can effectively increase the stability of the device.

[0026] The grinding brush body 3 is an existing device, and the present application does not impose too many restrictions on the model of the grinding brush body 3. The grinding brush body 3 can be used to grind copper processed parts, and the accuracy of the copper processed parts can be higher.

[0027] A bearing 7 is embedded on the left side of the outer disc frame 1, and the inner wall of the bearing 7 is fixedly connected to the outer surface of the rotating shaft 2. The bearing 7 can reduce the friction generated when the rotating shaft 2 rotates, which can effectively increase the service life of the device and make the rotation of the rotating shaft 2 easier.

[0028] The outer surface of the left rotating shaft 2 of the two rotating shafts 2 is fixedly connected with a coupling 8, and the inner wall of the coupling 8 is provided with a thread. The coupling 8 can be used to connect to an external driving mechanism, making the device more convenient when connected to the outside, and can effectively increase the practicality of the device.

[0029] The outer surfaces of the two connecting shafts 4 are fixedly connected with protective plates 9, and the outer surfaces of the protective plates 9 are passivated. The protective plates 9 can protect the grinding brush body 3, effectively prevent the grinding brush body 3 from being hit, and effectively increase the safety of the device.

[0030] Two connecting mechanisms 5 are arranged on the outside of the grinding brush body 3, and the connecting mechanism 5 includes a connecting sleeve 501, and the inner wall of the connecting sleeve 501 is fixedly connected to two fixed boxes 502, and the inner wall of the fixed box 502 is slidably connected to a first telescopic spring 503, and the outer surface of the first telescopic spring 503 is fixedly connected to a sliding column 504, and the other end of the sliding column 504 is fixedly connected to the inner wall of the fixed box 502.

[0031] See also Figure 3 to Figure 4The connecting sleeve 501 can slide on the outer surfaces of the rotating shaft 2 and the connecting shaft 4. The movement of the connecting sleeve 501 can drive the fixed box 502 to move, and then drive the sliding column 504 to deform and shrink. The elastic force generated by the deformation of the sliding column 504 can drive the fixed box 502 to automatically reset, and then drive the connecting sleeve 501 to automatically reset.

[0032] See also Figure 3 to Figure 4 The connecting sleeve 501, the fixing box 502, the sliding column 504 and the sliding column 504 can connect the rotating shaft 2 and the connecting shaft 4, so that the rotating shaft 2 and the connecting shaft 4 can move synchronously, and then the grinding brush body 3 can be driven to rotate by the rotation of the rotating shaft 2.

[0034] See also Figures 1 to 4 When moving the connecting sleeve 501, you first need to pull the moving disk 505. The moving disk 505 can drive the limiting rod 506 to be pulled out from the inside of the fixed box 502 and the sliding column 504, so that the limiting of the connecting sleeve 501 can be released, and then the connecting sleeve 501 can be pulled to move, so that the connection between the rotating shaft 2 and the connecting shaft 4 can be released.

[0035] See also Figures 1 to 4 The elastic force generated by the deformation of the second telescopic spring 507 can drive the movable plate 505 to automatically reset, which can make the operation of the device more convenient and quick. The movable plate 505 can achieve the purpose of limiting the fixed box 502 and the sliding column 504, and can avoid the shaking of the connecting sleeve 501 when the rotating shaft 2 is connected to the connecting shaft 4, which can effectively increase the safety of the device.

[0036] A connecting plate 508 is provided on the outside of the outer disc frame 1, and the two ends of the connecting plate 508 are respectively fixedly connected to the outer surfaces of the two movable discs 505.

Threaded holes 11 are provided at the four corners of the upper surface of the mounting plate 10. The mounting plate 10 can support and fix the device. Because the device is relatively large as a whole, the mounting plate 10 needs to be made of a material with higher hardness, which can effectively avoid damage to the device caused by breakage of the mounting plate 10. The threaded holes 11 can make it more convenient for the staff to install the device.

[0038] The inner wall of the threaded hole 11 is threadedly connected with a bolt 12, and the top of the bolt 12 is fixedly connected with a nut 13.

[0039] A reinforcing rod 15 is arranged above the outer disc frame 1, and the side surfaces of the two outer disc frames 1 that are close to each other are fixedly connected to the left and right ends of the reinforcing rod 15 respectively.

[0040] Working principle: When the device is used, it first needs to be installed on the grinder, and then connected to the external driving mechanism through the coupling 8.

When the grinding brush body 3 needs to be replaced, the pull rod 6 needs to be pulled first, and the pull rod 6 can drive the connecting plate 508 to move, and then the moving plate 505 can be driven to move. With the movement of the moving plate 505, the limit rod 506 can be pulled out from the inside of the fixed box 502 and the sliding column 504, so that the fixed box can be replaced. The purpose of releasing the limit of 502 and the sliding column 504 is that the second telescopic spring 507 can be deformed with the movement of the movable plate 505, and then the connecting sleeve 501 is moved, and the fixed box 502 can be driven to move through the connecting sleeve 501, and the sliding column 504 can be driven to deform with the movement of the fixed box 502. When the fixed box 502 slides out from the inside of the connecting shaft 4, the connection between the rotating shaft 2 and the connecting shaft 4 is released, and then the grinding brush body 3 is disassembled, and then the above operation is reversed to install the grinding brush body 3, and then the grinding brush body 3 can be replaced.
