Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing and processing technology, and in particular to a tire fixing mechanism for tire manufacturing and processing. Background Technology

[0002] In the tire manufacturing industry, securing the tire inner ring is a crucial step in ensuring processing accuracy and efficiency. Existing tire securing mechanisms have several shortcomings when fixing the tire inner ring. Some mechanisms use a single fixing method, making it difficult to adapt to tire inner rings of different radii. When dealing with tires of various sizes, they cannot achieve precise and stable fixing, leading to problems such as tire wobbling and displacement during processing, severely affecting processing quality. Other securing mechanisms have complex structures, making the fixing and disassembly of the tire inner ring cumbersome and requiring significant manpower and time, greatly reducing production efficiency. Therefore, designing a securing mechanism that can effectively clamp the tire inner ring and flexibly adapt to tires of different radii has become an urgent problem to be solved in the tire manufacturing industry. Utility Model Content

[0003] To address the problems mentioned above, this utility model adopts the following technical solution: a tire fixing mechanism for tire production and processing, comprising a circular worktable, two arc-shaped clamps on the top of the circular worktable, a nut seat at the bottom of each arc-shaped clamp, and guide blocks connected to the bottom sides of each arc-shaped clamp. The top of the circular worktable is respectively provided with a through groove for the movement of the nut seat and a guide groove for the sliding of the guide blocks. Bearing seats are installed at both ends of the through grooves at the bottom of the circular worktable, and a bidirectional threaded rod is rotatably connected between the bearing seats. The two nut seats are respectively connected to the bidirectional threaded rod with a left-hand thread and a right-hand thread. A circular support platform is connected to the bottom of the circular worktable, and a forward / reverse motor is installed inside the circular support platform. A pulley is connected to the output end of the forward / reverse motor and one end of the bidirectional threaded rod, and the two pulleys are connected by a belt drive.

[0004] Furthermore, the outer side of the arc-shaped clamp is provided with anti-slip texture.

[0005] Furthermore, the guide block is a cylindrical shape, and a bearing is mounted on the surface of the guide block, which slides within the guide groove.

[0006] Furthermore, the bidirectional threaded rod has a smooth shaft section in the middle, and the diameter of the smooth shaft section is smaller than the diameter of the threaded section.

[0007] Furthermore, the bottom of the circular support platform is provided with shock-absorbing feet.

[0008] The advantages of this invention are as follows: By setting two arc-shaped clamps and coordinating them with the connection structure of the bidirectional threaded rod and the nut seat, the two arc-shaped clamps can expand outward to accurately clamp the inner ring of the tire, providing a stable fixation and effectively preventing tire displacement or shaking during processing, thus significantly improving processing accuracy. The anti-slip texture on the outer side of the arc-shaped clamps further enhances the clamping force on the inner ring of the tire, preventing slippage. The cooperation between the guide block and the guide groove, as well as the bearing on the surface of the guide block, makes the arc-shaped clamps move more smoothly and stably during expansion or contraction, reducing friction and wear between components and extending the service life of the mechanism. The optical shaft section design in the middle of the bidirectional threaded rod optimizes the overall structure and reduces manufacturing costs. The shock-absorbing feet at the bottom of the circular support platform effectively absorb the vibration generated during the operation of the mechanism, reducing noise and improving the stability and reliability of the mechanism. In addition, the expansion degree of the two arc-shaped clamps can be flexibly adjusted according to the different radii of the inner ring of the tire, thereby adapting to various tire specifications and greatly improving the versatility and practicality of the equipment.

[0014] See Figure 1-2 As shown, a tire fixing mechanism for tire production and processing includes a circular worktable 1. Two arc-shaped clamps 2 are provided on the top of the circular worktable 1. Nut seats 3 are provided at the bottom of each of the two arc-shaped clamps 2. Guide blocks 4 are connected to the two sides of the bottom of the arc-shaped clamps 2 respectively. The top of the circular worktable 1 is provided with a through groove 5 for moving the nut seats 3 and a guide groove 6 for sliding the guide blocks 4. Bearing seats 7 are installed at both ends of the through groove 5 at the bottom of the circular worktable 1. A bidirectional threaded rod 8 is rotatably connected between the bearing seats 7. The two nut seats 3 are respectively connected to the bidirectional threaded rod 8 with left-hand thread and right-hand thread. A circular support platform 9 is connected to the bottom of the circular worktable 1. A forward and reverse motor 10 is installed in the circular support platform 9. The output end of the forward and reverse motor 10 and one end of the bidirectional threaded rod 8 are both connected to pulleys 11. The two pulleys 11 are connected by belt drive.

[0015] The outer side of the arc-shaped clamp 2 is provided with anti-slip texture; this effectively increases the friction between the arc-shaped clamp 2 and the inner ring of the tire, so that even if the tire is subjected to external force during processing, the tire can be firmly clamped to prevent it from slipping or shifting.

[0016] The guide block 4 is a cylindrical shape, and a bearing 41 is installed on the surface of the guide block 4. The bearing 41 slides in the guide groove 6, which significantly reduces the frictional resistance of the arc-shaped clamp 2 during the movement process, so that the two arc-shaped clamps 2 can perform expansion or contraction movements more smoothly and steadily under the drive of the bidirectional threaded rod 8.

[0017] The bidirectional threaded rod 8 has a smooth shaft section 81 in the middle. The diameter of the smooth shaft section 81 is smaller than that of the threaded section. This ensures that the bidirectional threaded rod 8 can effectively drive the nut seat 3 to achieve the expansion and contraction function of the arc clamp 2, while preventing the two arc clamps 2 from collapsing when they retract inward at the same time.

[0018] The bottom of the circular support platform 9 is equipped with shock-absorbing feet 91, which can effectively absorb the vibration generated by the fixing mechanism during operation, reduce the impact of vibration on the fixing mechanism itself and surrounding equipment, and reduce the noise during equipment operation.

[0019] Working Principle: When the tire needs to be fixed, the forward and reverse motor 10 inside the circular support platform 9 is activated. The pulley 11 at the output end of the forward and reverse motor 10 drives the pulley 11 at one end of the bidirectional threaded rod 8 to rotate via a belt, thereby causing the bidirectional threaded rod 8 to rotate between the bearing seats 7. Since the two nut seats 3 are respectively connected to the left-hand and right-hand threads of the bidirectional threaded rod 8, when the bidirectional threaded rod 8 rotates, the two nut seats 3 will move in opposite directions along the through groove 5. The nut seats 3 drive the arc-shaped clamp 2 connected to them to move synchronously. The guide blocks 4 on both sides of the bottom of the arc-shaped clamp 2 slide in the guide groove 6. The bearings 41 on the surface of the guide blocks 4 can reduce friction during the sliding process and ensure smooth movement of the arc-shaped clamp 2. As the two arc-shaped clamps 2 continue to expand outward, they gradually extend into the inner ring of the tire and clamp it tightly. When the processing is completed and the tire needs to be released, the forward and reverse motor 10 is activated in reverse, causing the two arc-shaped clamps 2 to move in opposite directions, thereby releasing the tire. Throughout the entire operation, the shock-absorbing feet 91 at the bottom of the circular support platform 9 effectively absorb the vibrations generated by the mechanism's operation, ensuring stable operation. Meanwhile, the anti-slip texture on the outer side of the arc-shaped clamp 2 enhances the clamping effect on the tire's inner ring, and the optical shaft section 81 in the middle of the bidirectional threaded rod 8, while ensuring functionality, prevents the two arc-shaped clamps 2 from collapsing simultaneously as they retract, enabling the mechanism to adapt to the fixing requirements of tire inner rings with different radii.
