[0018] 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.

[0019] Please see Figure 1 An embodiment of this utility model provides a hydraulic cylinder barrel inner wall repair device, including: a support platform 1.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, a rodless cylinder 7 is installed on the top of the support platform 1. A movable cylinder 9 is installed on the rodless cylinder 7 via a slider 8. A connecting rod 16 is installed at one end of the movable cylinder 9 via a bearing. A ring plate 10 is threaded to one side of the connecting rod 16. A grinding brush 11 is provided on the outer wall of the ring plate 10. The rodless cylinder 7 can drive the slider 8 to move the movable cylinder 9 along the slide rail, thereby facilitating the grinding brush 11 to move and grind along the inner wall of the hydraulic cylinder.

[0021] Among them, such as Figures 1-3 As shown, a motor 4 is installed on the top of the support platform 1. A rotating rod 6 is installed on the rotating shaft of the motor 4. The outer wall of the rotating rod 6 is provided with key teeth 12. The inside of the connecting rod 16 is provided with a keyway 18. The key teeth 12 and the keyway 18 are keyed together. A limit block 17 is fixedly connected to the end of the rotating rod 6 away from the motor 4. When the motor 4 is started, the rotating rod 6 is driven to rotate. The key teeth 12 on the outer wall of the rotating rod 6 mesh with the keyway 18 inside the connecting rod 16, thereby causing the connecting rod 16, the annular plate 10 and the grinding brush 11 to rotate. Under the drive of the rodless cylinder 7, the grinding brush 11 rotates and grinds while moving.

[0022] It should be noted that the rotating shaft of motor 4 is connected to one end of rotating rod 6 via coupling 5.

[0023] To facilitate the clamping and installation of the hydraulic cylinder barrel, a first arc plate 2 is fixedly connected to the top of the support platform 1, and a second arc plate 3 is provided on the top of the first arc plate 2. The cylinder barrel 15 is provided inside the first arc plate 2 and the second arc plate 3. A cylindrical tube clamp structure is formed between the first arc plate 2 and the second arc plate 3 to facilitate the clamping of the cylinder barrel 15.

[0024] like Figures 1-4 As shown, multiple adjusting bolts 19 are equidistantly arranged on the adjacent surfaces of the first arc plate 2 and the second arc plate 3. By rotating the adjusting bolts 19, the clamping force between the first arc plate 2 and the second arc plate 3 can be increased, further stabilizing the cylinder 15.

[0025] Specifically, a bracket 13 is installed at the bottom of the support platform 1, which can provide support and stability for the support platform 1.

[0026] Based on the above technical solution, the working steps of this solution are summarized as follows: When this utility model is used, the starting motor 4 drives the rotating rod 6 to rotate. The key teeth 12 on the outer wall of the rotating rod 6 mesh with the keyway 18 inside the connecting rod 16, thereby causing the connecting rod 16, the annular plate 10 and the grinding brush 11 to rotate. The connecting rod 16 is connected to the movable cylinder 9 through the bearing. The rodless cylinder 7 can drive the slider 8 to move the movable cylinder 9 along the slide rail, thereby facilitating the grinding brush 11 to move and grind along the inner wall of the hydraulic cylinder, uniformly repairing the inner wall of the cylinder, restoring the smoothness and performance of the cylinder, without the need to rotate the cylinder body, and the grinding effect is stable.
