Description

Technical Field

[0001] This utility model relates to the field of tire changing machine technology, specifically to a tire changing mechanism for a tire changing machine. Background Technology

[0002] Currently, some repair shops use tire removal devices to pull the outer tire out of the rim. The tire removal mechanism mainly consists of a mechanism for fixing the inner ring of the rim, a tire removal mechanism for pulling the outer tire out of the rim, and an auxiliary mechanism. After the tire removal is completed, the outer tire will be pressed on the tire removal arm.

[0003] Existing tire changers have a simple adjustment structure for their tire-changing mechanisms. The main components, such as the tire-changing clamps, are mostly connected by fixed or limited movement. They can usually only move on simple straight tracks or rely on manual rotation of joints for fine adjustments. This structure makes it difficult to quickly and accurately adjust the tire-changing clamps to the appropriate position and angle when changing tires of different sizes and specifications. For example, when dealing with off-road tires with thick sidewalls and large rim diameters versus passenger car tires with thin sidewalls and small rim diameters, existing tire-changing clamps cannot quickly switch working postures. Operators need to repeatedly disassemble and reassemble the tire-changing clamps and manually calibrate their position and angle, which consumes a lot of time for manual adjustments and greatly reduces tire-changing efficiency.

[0005] Therefore, the purpose of this utility model is to provide a tire-changing mechanism for a tire changer, which solves the problem that the main components such as the tire-changing clamps in the existing tire-changing mechanism are not easy to adjust and move flexibly to adapt to tires of different specifications and sizes for tire-changing operations.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a tire-changing mechanism for a tire-changing machine.

[0027] This utility model provides, for example Figure 1-4 The tire-changing mechanism of the tire-changing machine shown includes a base 1. A motor 2 is fixedly connected to the cavity of the base 1 through a pushing mechanism. A worktable 3 is rotatably connected to the top of the motor 2. A positioning threaded port 4 is opened on the top of the worktable 3, and a threaded limiting pressure plate device 5 is threadedly connected to it. Lifting chambers 6 are fixedly connected to both side walls of the base 1. An adjusting support device 7 is fixedly connected to the cavity of the lifting chambers 6 through an adjusting mechanism. A rotary chuck device 8 and a tire-changing clamp 9 are fixedly connected to the other end of the adjusting support device 7, respectively.

[0028] Both ends of the adjustable support device 7 include a connecting chamber 10. A U-shaped plate 11 is fixedly connected to one end of the connecting chamber 10. A rotating arm 12 is rotatably connected between the two ends of the U-shaped plate 11. The side walls of the rotating arms 12 are fixedly connected to one end of the rotating chuck device 8 and the tire-changing clamp 9, respectively. A slide rail 13 is fixedly connected to the side walls of the rotating arms 12. A first hydraulic cylinder 14 is fixedly connected inside the cavity of the connecting chamber 10. The other end of the first hydraulic cylinder 14 passes through the side wall of the connecting chamber 10 and is fixedly connected to a limiting sleeve 15. The limiting sleeve 15 is slidably connected to the slide rail 13. The propulsion mechanism drives the motor 2 and the worktable 3 to move, and the position of the worktable 3 can be flexibly adjusted to adapt to the tire-changing needs of different tire sizes. The motor 2 can drive the worktable 3 to rotate, which facilitates precise multi-angle tire operation. The threaded limiting pressure plate device 5 is connected to the worktable 3 through the positioning thread 4, which can stabilize the tire. The system securely clamps the tire, effectively preventing tire displacement during tire removal. The lifting chamber 6, in conjunction with the adjustment mechanism, precisely controls the position of the adjustment support device 7, thereby flexibly adjusting the height and angle of the rotating chuck device 8 and the tire-removing clamp 9. This significantly improves the applicability to tires of different specifications. The first hydraulic cylinder 14 drives the limiting sleeve 15 to slide on the slide rail 13, causing the rotating arm 12 to rotate flexibly between the U-shaped plates 11. This allows for precise angle adjustment of the rotating chuck device 8 and the tire-removing clamp 9. This structure enables the rotating chuck device 8 and the tire-removing clamp 9 to quickly adjust their posture, closely conforming to the tread contours of tires of different specifications, greatly improving the efficiency and success rate of tire removal operations. Simultaneously, it reduces the risk of tire damage due to improper posture adjustment, thus solving the problem that the main components of existing tire-removing machines, such as the tire-removing clamp, are not easily adjustable and movable to adapt to tires of different specifications and sizes.

[0029] In order to adjust the position of workbench 3, such as Figure 1-3 The propulsion mechanism includes a first limiting slide 16, a first limiting slider 17, a sliding support seat 18, and an electric push rod 19. The top of the base 1 has a first limiting slide 16 and a first limiting slider 17 is slidably connected thereto. The top of the first limiting slider 17 is fixedly connected to the sliding support seat 18. The motor 2 is fixedly connected inside the cavity of the sliding support seat 18. The bottom of the worktable 3 is rotatably connected to the top of the sliding support seat 18. One end of the cavity of the base 1 is fixedly connected to the electric push rod 19. One end of the electric push rod 19 is fixedly connected to the side wall of the first limiting slider 17. The electric push rod 19 drives the first limiting slider 17 to slide within the first limiting slide 16, thereby moving the sliding support seat 18 and the motor 2. This allows for adjustment of the position of the worktable 3, quickly adapting to the tire changing station requirements of different tire sizes and improving the equipment's versatility.

[0030] In order to adjust the height and horizontal position of the adjusting support device 7, such as Figure 1-4The adjustment mechanism includes a second limiting slide 20, a second limiting slider 21, a second hydraulic rod 22, and a third hydraulic rod 23. The side walls of both lifting chambers 6 have second limiting slides 20, and each is slidably connected to a second limiting slider 21. The cavities of the second limiting sliders 21 at both ends are fixedly connected to the second hydraulic rods 22. The other ends of the second hydraulic rods 22 at both ends are fixedly connected to the side walls of the corresponding adjustment support device 7. The cavities of the lifting chambers 6 at both ends are fixedly connected to the third hydraulic rods 23, and the other ends of the third hydraulic rods 23 at both ends are fixedly connected to the bottom of the corresponding second limiting slider 21. Using the adjustment mechanism composed of the second limiting slide 20, second limiting slider 21, second hydraulic rod 22, and third hydraulic rod 23, the third hydraulic rod 23 drives the second limiting slider 21 to slide up and down within the second limiting slide 20, thereby adjusting the height of the adjustment support device 7. The second hydraulic rod 22, through extension and retraction, can push the support device 7 to adjust its horizontal position, enabling precise positioning of the rotating chuck device 8 and the tire clamp 9.

[0031] To secure the tire firmly and prevent it from slipping during tire removal, such as Figure 1-3 As shown, the threaded limiting pressure plate device 5 includes a threaded shaft 24, with a rubber anti-slip pressure plate 25 fixedly connected to the top of the threaded shaft 24. A rotating seat 26 is fixedly connected to the top of the rubber anti-slip pressure plate 25. By rotating the rotating seat 26, the threaded shaft 24 at the bottom of the rubber anti-slip pressure plate 25 is driven to rotate in and out of the positioning threaded opening 4, thus adjusting the clamping force of the rubber anti-slip pressure plate 25. The rubber anti-slip pressure plate 25 increases the friction with the tire surface, which can firmly fix the tire, prevent the tire from slipping when removing the tire, and improve the safety of operation.

[0032] To facilitate the insertion of the tire clamps 9, such as Figure 1 and 2 As shown, the rotating chuck device 8 includes a second motor 27, one end of which is fixedly connected to a disassembly chuck 28. The disassembly chuck 28 is driven to rotate by the second motor 27, which can quickly insert a tire during the rotation process, loosening and separating the tire from the rim, making it easier to insert the tire-removing clamps 9.

[0033] To prevent tire slippage and ensure a smooth and efficient tire removal process, such as... Figure 1 , 2 As shown in Figure 4, an anti-slip tooth block 29 is fixedly connected to one side wall of the tire-removing clamp 9. The anti-slip tooth block 29 increases the friction between the tire-removing clamp 9 and the tire tread, allowing the tire-removing clamp 9 to hold the tire more firmly during the tire removal process, effectively preventing the tire from slipping, ensuring a smooth and efficient tire removal operation, and improving the adaptability of the tire removal mechanism to tires with different tread materials.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
