Description

Technical Field

[0001] This utility model relates to the field of tire processing, specifically a tire fixing mechanism for tire production and processing. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance.

[0003] After production, tires need to be processed, such as installing vent holes. This requires quick clamping and positioning of the tires. Common tire fixing methods often rely on manual operation or motor-driven clamping devices. Manual fixing is inefficient, inconsistent, and labor-intensive. While electric or pneumatic clamping mechanisms can improve efficiency, they are complex in structure, require multiple drive units, and have high system costs. Furthermore, they require position debugging and system initialization before each use, making the operation process cumbersome and difficult to adapt to the needs of high-efficiency and flexible production. Based on this, this utility model proposes a tire fixing mechanism for tire production and processing that is simple in structure, easy to operate, requires no external power, and can achieve rapid positioning and locking.

[0009] As a further improvement of this utility model: the inner side of the extrusion groove matches the outer wall of the clamping rod, and the inner side of the guide groove is formed with a sliding groove for the clamping rod to slide axially.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting up a transmission mechanism, when it is necessary to clamp and fix the tire, the tire can be placed between three limiting rods. After manually applying an outward pulling force to the movable rod, the turntable rotates circumferentially along the outer wall of the fixed plate's shaft.

[0013] 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.

[0014] Please see Figures 1-3 In this embodiment of the present invention, a tire fixing mechanism for tire production and processing includes a fixing disk 2 fixed by a shaft, a turntable 1 rotatably connected to the outer wall of the shaft of the fixing disk 2, a clamping rod 3 axially slidably installed on the inner side of the fixing disk 2, the clamping rod 3 being used to clamp and fix the tire, and a transmission mechanism 4 provided on the turntable 1 and the fixing disk 2 for guiding the clamping of the tire. Transmission mechanism 4 includes a guide unit and a transmission unit; The guide unit is used to guide the clamping rods 3 to move closer together; The transmission unit is used to provide power for the movement of the clamping rod 3; The guiding unit includes an extrusion groove 401 and a guide groove 402; Three extrusion grooves 401 are equidistantly distributed circumferentially on the outer wall of the turntable 1, and three guide grooves 402 are equidistantly distributed circumferentially on the outer wall of the fixed plate 2. The outer wall of the extrusion grooves 401 is generally arc-shaped. The transmission unit includes a limiting groove 403, a movable rod 404, a limiting rod 405, and a spring 406; The limiting groove 403 is formed on the outer wall of the fixed plate 2. Multiple limiting grooves 403 are distributed at a 45-degree angle. The movable rod 404 is axially slidably installed on the inner wall of the turntable 1 and extends to the outside of the turntable 1. The limiting rod 405 is fixed on the outer wall of the movable rod 404 and extends to the inner side of a limiting groove 403. The limiting rod 405 is used to cooperate with the movable rod 404 to limit the rotation of the turntable 1. The two ends of the spring 406 are respectively connected to the inside of the turntable 1 and the outside of the movable rod 404. The spring 406 is used to always provide the spring 406 with a return force.

[0015] In this embodiment: when the tire needs to be processed, the tire to be processed is placed between the three clamping rods 3. By applying an outward pulling force to the movable rod 404, the movable rod 404 will simultaneously drive the limiting rod 405 to move outward and apply a compressive force to the spring 406. The limiting rod 405 will also move out from the inside of the limiting groove 403. At this time, the movable rod 404 can provide rotational power to the turntable 1, causing the turntable 1 to drive the extrusion groove 401 to rotate circumferentially. The extrusion groove 401, in its arc shape, applies a compressive force to the clamping rods 3. The clamping rods 3 inside the extrusion groove 401 move axially along the inner side of the guide groove 402. The three clamping rods 3 move closer to each other to clamp the tire. After clamping, the tension on the movable rod 404 can be released, and the movable rod 404 is reset under the action of the spring 406. The reset spring 406 will be inserted into the inner side of a limiting groove 403 to limit the rotation of the turntable 1, thus achieving the purpose of quickly clamping the tire. This eliminates the preparation time for connecting pipelines, checking pressure, and starting the equipment, and further improves work efficiency.

[0016] Please refer to this carefully. Figures 1-3The outer wall of the limiting rod 405 matches the inner side of the limiting groove 403, and the outer wall of the movable rod 404 has an overall "T" shaped structure.

[0017] In this embodiment: this structure allows the movable rod 404 to be subjected to force when it moves, and the protruding part at one end of the movable rod 404 will apply a compressive force to the spring 406.

[0018] Please refer to this carefully. Figures 1-3 The inner side of the extrusion groove 401 matches the outer wall of the clamping rod 3, and the inner side of the guide groove 402 is formed with a sliding groove for the clamping rod 3 to slide axially.

[0019] In this embodiment, this structure provides guidance for the axial movement of the clamping rod 3.
