By effectively fixing the material, the fixture can reduce waste caused by misoperation or material displacement, reducing production costs.
[0003] Traditional fixture design is complex and has high operating costs, and is prone to falling off when clamping the tire. UTILITY MODEL CONTENTS
[0004] Therefore, the utility model provides a fixture for tire production equipment, which can solve the problems of complex design, high operating cost and easy falling off when clamping the tire of the traditional fixture.
[0005] The utility model is implemented as follows:
[0006] The utility model provides a fixture for tire production equipment, which comprises a base, a clamping arm, a clamping jaw and a triangular support frame. Three clamping arms are fixed to one side of the base. The clamping arms are fixedly connected to the base, and form an equilateral triangle structure on the base. A clamping groove is provided at the middle position of each clamping arm. The triangular support frame is fixed in the clamping groove to fix the angle of the clamping arms and prevent them from rotating. A clamping jaw is fixed to the side of each clamping arm away from the base. The clamping jaw is used to contact and clamp the tire. Three clamping jaws are fixed to different positions of the tire, and the projections of adjacent clamping jaws on the horizontal plane are separated by 120 degrees.
[0007] On the basis of the above technical scheme, the clamp for tire production equipment can be further improved as follows:
[0008] The clamping arm comprises a fixed arm and a rotating arm, one end of the fixed arm is fixed on the top of the base, and the other end is rotatably connected with the rotating arm through a spherical part.
[0009] Further, the spherical part comprises a spherical groove and a spherical roller, the spherical groove is arranged on the side of the fixed arm away from the base, the size of the port position of the spherical groove is smaller than the size of the internal hollow, one end of the spherical of the spherical roller is fixed in the internal of the spherical groove, and the other end is fixed in the internal of the side of the rotating arm close to the fixed arm.
[0010] Further, the size of the spherical of the spherical roller is smaller than the size of the internal hollow of the spherical groove and larger than the size of the port position of the spherical groove.
[0011] Further, the fixed arm and the rotating arm are arranged at an angle, and the size between the three clamping jaws is adjusted by rotating the rotating arm to clamp tires of different sizes.
[0012] Further, the side of the fixed arm and the rotating arm arranged at an acute angle is fixed with a tension spring, and the tension spring is used to fix the position and angle of the rotating arm after the clamping jaw clamps the tire.
[0013] Further, each clamping jaw comprises a three-jaw structure, the end position of the three-jaw structure is provided with an elastic element, the elastic element is bent inward to form a hook structure to fix the tire.
[0014] Further, the side of the clamping jaw in contact with the tire is provided with a friction pattern for increasing the friction force when the clamping jaw contacts the tire to prevent sliding.
[0015] Further, the side wall of the rotating arm is provided with a plurality of clamping grooves, and the triangular support frame is clamped in different clamping grooves according to the size and shape of the clamped tire to fix the position of the rotating arm.
[0016] Further, the size of the triangular support frame is selected according to the size and angle of the clamped tire.
[0017] The beneficial effects of the above improvement scheme are that the base provides stability and support as the basis of the entire clamp, so that the clamping arm can reliably fix and bear the weight of the tire.
[0018] The clamping arm, through a combination of a fixed arm and a rotating arm, allows for flexible adjustment of the distance between the grippers, thus accommodating tires of different sizes. The rotation of the rotating arm easily enables the clamping and release of the tire.
[0019] The grippers are responsible for direct contact with the tire to ensure clamping force. The three-jaw structure and elastic element design enhance the clamping effect, and the friction grooves increase friction when in contact with the tire, preventing slippage.
[0020] The triangular support frame, through its slotted engagement with the clamping arm, prevents the clamping arm from rotating during clamping, ensuring that the clamp remains at the required angle, thereby improving the accuracy and stability of clamping.
[0021] Compared with the prior art, the advantages of the fixture for tire production equipment provided by this utility model are:
[0022] The base is the foundation of the entire clamp, providing the necessary stability to ensure that the clamp does not move or tilt during operation. The base is typically designed using robust materials (such as steel or aluminum alloy) to support the weight of the clamp and the held tire. Three clamping arms are fixed to one side of the base, forming an equilateral triangle structure, which allows the clamp to distribute force evenly when holding the tire, reducing stress concentration. The structural design of the base ensures a secure connection between the clamping arms, preventing the clamp from easily loosening during operation.
[0023] The clamping arm consists of a fixed arm and a rotating arm, allowing for adjustment of the jaw distance via rotation to accommodate tires of different sizes, thus enhancing the clamp's versatility. Through a spherical connector, the clamping arm can rotate freely, allowing for fine-tuning during operation and improving clamping accuracy. The clamping arm's material design requires good strength and durability, capable of withstanding the forces applied when clamping the tire without deformation. A slot is located in the middle of the clamping arm, which can be combined with a triangular support frame to ensure a stable clamping angle and prevent rotation during clamping.
[0024] The grippers are used to directly contact the tire, clamping it by generating friction with the tire surface to ensure the tire does not slip during processing. Each gripper has a three-jaw structure with elastic elements at its ends, forming a hook structure to increase the reliability and safety of clamping. Friction grooves are provided on the side of the gripper that contacts the tire, increasing the friction between the gripper and the tire and ensuring stability during clamping. The projection interval between adjacent grippers on the horizontal plane is 120°, allowing the clamp to apply force evenly when holding the tire and avoiding localized stress concentration.
[0025] The triangular support bracket is fixed in the slot of the clamping arm, ensuring the angle of the clamping arm is stable and preventing rotation during clamping, thus maintaining the overall stability of the clamp. The size and angle of the triangular support bracket can be selected according to the size and shape of the tire being clamped, enhancing the flexibility and adaptability of the clamp. Multiple slots are provided on the side wall of the rotating arm, allowing users to adjust the installation position of the triangular support bracket according to the specific tire conditions to optimize the clamping effect.
[0026] The spherical component between the fixed arm and the rotating arm provides greater rotational freedom, enhancing the flexibility of the clamp.
[0027] The tension spring is used to fix the position and angle of the rotating arm after the gripper clamps the tire, ensuring a stable and reliable clamping state.
[0028] The elastic elements and friction texture design on the grippers not only improve the gripping effect, but also make the tire more secure and reduce the risk of slippage. Attached Figure Description

[0036] like Figs. 1-3The image shows an embodiment of a clamp for tire production equipment provided by this utility model.

Three clamping arms 20 are fixed to one side of the base 10, and the three clamping arms 20 are fixedly connected to the base 10, forming an equilateral triangle structure on the base 10. The middle position of each clamping arm 20 is provided with a slot, and the triangular support frame 40 is fixed in the slot to fix the angle of the three clamping arms 20 to prevent them from rotating.

The three grippers 30 are fixed at different positions on the tire, and the projection interval between adjacent grippers 30 on the horizontal plane is 120°.
[0037] In the above technical solution, the clamping arm 20 includes a fixed arm 21 and a rotating arm 22. One end of the fixed arm 21 is fixed to the top of the base 10, and the other end is rotatably connected to the rotating arm 22 through a spherical component.
[0038] Furthermore, in the above technical solution, the spherical component includes a spherical groove and a spherical roller. The spherical groove is located on the side of the fixed arm 21 away from the base 10, and the size of its port position is smaller than the size of the internal hollow. One spherical end of the spherical roller is fixed inside the spherical groove, and the other end is fixed inside the side of the rotating arm 22 close to the fixed arm 21.
[0039] Furthermore, in the above technical solution, the spherical size of the spherical roller is smaller than the internal hollow size of the spherical groove, but larger than the size of the port position of the spherical groove.
[0040] Furthermore, in the above technical solution, the fixed arm 21 and the rotating arm 22 are set at an angle, and the size between the three grippers 30 is adjusted by rotating the rotating arm 22 to clamp tires of different sizes.
[0041] Furthermore, in the above technical solution, a tension spring is fixed on the side where the fixed arm 21 and the rotating arm 22 are set at an acute angle. The tension spring is used to fix the position and angle of the rotating arm 22 after the gripper 30 clamps the tire.

[0046] The clamp applies mechanical pressure to the tire through its jaws, using friction to ensure the tire is firmly fixed and prevent slippage during processing.
[0047] The clamping arm is designed as a lever structure. By adjusting the rotation of the arm, the clamping force and clamping angle can be effectively changed to adapt to tires of different sizes.
[0048] The triangular support frame forms a stable geometry, distributing the force applied to the clamp and ensuring that the force is evenly distributed during clamping, thus reducing stress concentration.
[0049] The spherical connection between the clamping arm and the base allows for free rotation, enabling the clamp to be finely adjusted during clamping, thus improving clamping accuracy and flexibility.
[0050] The elastic element on the gripper can provide a certain amount of elasticity, enabling the clamp to adapt to slight changes in the tire surface during clamping and enhancing the reliability of clamping.
[0051] Specifically, the principle of this utility model is as follows: During use, ensure the clamp and tire are clean, and check that all parts of the clamp are intact. Adjust the position of the clamping arms and jaws according to the size and shape of the tire. Place the clamp on the tire production equipment, ensuring the base is firmly fixed. Adjust the position of the triangular support frame as needed to ensure the contact angle between the clamping arms and the tire is appropriate. Manually operate the clamping arms, gradually moving them closer to the tire, ensuring the jaws contact the tire surface. Continue adjusting the clamping arms until the jaws completely secure the tire. Ensure the contact between the jaws and the tire is tight and even, preventing slippage. Check that the clamp is secure and there is no looseness before starting the tire production equipment for the corresponding processing operations. During processing, periodically check the clamping status of the clamp to ensure safety. After production is complete, gradually loosen the clamping arms and gently separate the jaws from the tire. Carefully remove the tire, ensuring that all parts of the clamp are not damaged.
