Description

Technical Field

[0001] This utility model relates to the technical field of tire installation, and in particular to an auxiliary device for installing all-steel radial tires with a tire bead. Background Technology

[0002] Tire installation is a crucial step in automobile manufacturing and repair, and its quality directly affects tire lifespan and driving safety. During the installation of all-steel radial tires, the installation of the bead is particularly difficult due to the tire's large size and heavy weight. Therefore, auxiliary devices are used to assist in the installation, thereby improving efficiency and accuracy.

[0003] When using auxiliary devices to install the bead on all-steel radial tires, traditional devices often lack an effective cushioning mechanism. This results in the bead being subjected to significant impact during the opening process, which can easily damage the internal structure of the bead and affect the overall performance and lifespan of the tire. Therefore, most methods involve manually controlling the auxiliary device to slowly open the bead. However, this method is inefficient and makes it difficult to ensure the uniformity and stability of the bead opening, thus affecting the quality of tire installation. Utility Model Content

[0019] 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 embodiments described 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4 As shown, the present invention proposes an auxiliary device for installing tire bead on all-steel radial tires, comprising an auxiliary device 1 and a buffer mechanism 2.

[0021] The buffer mechanism 2 includes a spring 21, a guide block 23, a buffer head 24, a rubber buffer head 25, and a flexible protective sleeve 26. The spring 21 is disposed inside the auxiliary device 1, and one end of the spring 21 is connected to the auxiliary device 1. The guide block 23 is connected to the other end of the spring 21. The buffer head 24 is disposed on the outer wall of the guide block 23. The rubber buffer head 25 is disposed on the auxiliary device 1. The flexible protective sleeve 26 is disposed on the outer wall of the auxiliary device 1.

[0022] When installing the tire bead, first place the tire bead onto the four clamps 14, then start the motor 12. The motor 12's shaft drives the double-acting screw 13 to rotate, which in turn moves the clamps 14 outward. The four clamps 14 expand outward simultaneously, smoothly opening the tire bead to the predetermined diameter, ensuring the concentricity of the tire bead and the rim. During the opening process, the buffer head 24 first contacts the tire bead, providing initial cushioning to prevent damage to the internal structure due to excessive instantaneous force. Simultaneously, the spring 21 pushes the buffer head 24 towards the tire bead through the guide block 23, further cushioning and protecting the tire bead. The flexible protective sleeve 26 wraps around the outer wall of the positioning rod 16, preventing damage when the wheel hub is installed on the positioning rod 16. During the installation process, the edge of the wheel hub collides hard with the positioning rod 16, causing damage. After the tire bead is stretched to the predetermined diameter, the wheel hub is placed on the positioning rod 16. When the control motor 12 rotates in the opposite direction, the bidirectional lead screw 13 rotates in the opposite direction, driving the four grippers 14 to retract inward synchronously, so that the tire bead is stably placed on the tire bead seat of the wheel hub. At this time, the first cylinder 17 is activated. The output end of the first cylinder 17 pushes the rubber buffer head 25 to push out the installed tire assembly as a whole, making it easy for the operator to remove and complete the subsequent installation process. The rubber buffer head 25 is designed to prevent the output end of the first cylinder 17 from directly colliding with the wheel hub, further ensuring the safety of the installation process and avoiding unnecessary damage to the wheel hub and tire bead.

[0023] In one embodiment of this application, such as Figure 4 As shown, the auxiliary device 1 is equipped with a cleaning assembly 3. The cleaning assembly 3 includes a mounting plate 31, an electric slide 32, a second cylinder 33, a rotary cylinder 34, a connecting plate 35, an air gun 36, a connecting pipe 37, and an air pump 38. The mounting plate 31 is mounted on the auxiliary device 1, the electric slide 32 is mounted on the mounting plate 31, the second cylinder 33 is mounted on the electric slide 32, the rotary cylinder 34 is connected to the output end of the second cylinder 33, the connecting plate 35 is mounted on the output end of the rotary cylinder 34, the air gun 36 is mounted on the outer wall of the connecting plate 35, one end of the connecting pipe 37 is connected to the air gun 36, and the output end of the air pump 38 is connected to the other end of the connecting pipe 37.

[0024] Once the tire bead is placed on the clamp 14, the cleaning assembly 3 is activated. The electric slide 32 drives the second cylinder 33 to move towards the inside of the tire bead. Subsequently, the second cylinder 33 is activated, and its output pushes the rotary cylinder 34 and the air gun 36 closer to the inner wall of the tire bead. When the air gun 36 reaches the designated cleaning position, it is precisely aligned with the inside of the tire bead. At this time, the rotary cylinder 34 is activated, driving the connecting plate 35 and the air gun 36 to rotate. At this time, the air pump 38 works, delivering compressed air to the air gun 36 through the connecting pipe 37. The air gun 36 sprays high-pressure airflow to thoroughly clean the dust and impurities adhering to the inner wall of the tire bead, ensuring that the inner wall of the tire bead is clean and free of debris. This prevents foreign objects from affecting the installation quality and tire performance during subsequent installation.

[0025] In one embodiment of this application, such as Figure 1 As shown, the auxiliary device 1 includes a mounting rod 11, a motor 12, a bidirectional lead screw 13, a gripper 14, a fixing plate 15, a positioning rod 16, and a first cylinder 17. The motor 12 is mounted on the outer wall of the mounting rod 11. One end of the bidirectional lead screw 13 is connected to the rotating shaft of the motor 12, and the other end of the bidirectional lead screw 13 is connected to the mounting rod 11. The gripper 14 is mounted on the outer wall of the bidirectional lead screw 13. The fixing plate 15 is mounted on the outer wall of the mounting rod 11. The positioning rod 16 is mounted on the outer wall of the fixing plate 15. The first cylinder 17 is mounted on the outer wall of the fixing plate 15.

[0026] Mounting rod 11 serves as the basic support structure for the entire auxiliary device 1, ensuring it can withstand various forces generated during installation. Motor 12 is a high-performance servo motor with precise speed control and powerful torque output, capable of stably driving the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 has a special thread structure, which, when rotating, drives the grippers 14 on its outer wall to move synchronously in opposite directions. The surface of the grippers 14 is specially treated to have a high coefficient of friction, enabling them to firmly grip the tire bead and prevent it from slipping during the unfolding process. Fixing plate 15 serves to fix and support positioning rod 16 and first cylinder 17. The size of positioning rod 16 matches the size of the positioning hole of the wheel hub, accurately positioning the wheel hub and ensuring that the tire bead can be accurately fitted onto the tire bead seat of the wheel hub. First cylinder 17 uses standard pneumatic components, and its output force can be adjusted according to actual needs, enabling it to smoothly push out the installed tire assembly as a whole.

[0027] In one embodiment of this application, such as Figure 3As shown, a limiting post 22 is provided inside the spring 21, with one end of the limiting post 22 connected to the gripper 14 and the other end connected to the guide block 23. The limiting post 22 effectively limits the compression and extension range of the spring 21, preventing excessive deformation or displacement of the spring 21 during the force application process, thereby ensuring the stability and reliability of the buffer mechanism 2. When the gripper 14 expands outward or contracts inward, the limiting post 22 moves accordingly and always remains connected to the guide block 23. This allows the elastic force of the spring 21 to be accurately transmitted to the buffer head 24, achieving precise buffer protection for the tire bead. At the same time, the limiting post 22 also serves as a guide, guiding the guide block 23 to move along a predetermined trajectory, avoiding jamming or displacement, and further improving the working efficiency of the buffer mechanism 2.

[0028] In one embodiment of this application, such as Figure 4 As shown, heat dissipation fins 39 are provided on the outer wall of the air pump 38. The heat dissipation fins 39 effectively increase the heat dissipation area of ​​the outer surface of the air pump 38, accelerate the heat dissipation rate, and enable the air pump 38 to maintain a relatively stable temperature during operation. This ensures that the air pump 38 can continuously and stably provide compressed air to the air gun 36, guarantee the normal operation of the cleaning component 3, and improve the reliability and stability of the entire auxiliary device 1.

[0029] In one embodiment of this application, such as Figure 2 As shown, a first fixing bolt 4 is provided on the outer wall of the fixing plate 15, and the first fixing bolt 4 passes through the fixing plate 15 and is connected to the mounting rod 11. The setting of the first fixing bolt 4 can enhance the connection strength and stability between the fixing plate 15 and the mounting rod 11. During the operation of the auxiliary device 1, the fixing plate 15 needs to withstand various forces generated by components such as the positioning rod 16 and the first cylinder 17. By firmly fixing the fixing plate 15 to the mounting rod 11 with the first fixing bolt 4, it can effectively prevent the fixing plate 15 from loosening or displacing, ensuring the structural stability and operational reliability of the entire auxiliary device 1. At the same time, the installation and removal of the first fixing bolt 4 are relatively convenient, facilitating the maintenance and repair of the auxiliary device 1.

[0030] In one embodiment of this application, such as Figure 2As shown, a connecting block 5 is provided on the outer wall of the mounting rod 11, and a second fixing bolt 6 is provided on the outer wall of the connecting block 5. The second fixing bolt 6 passes through the connecting block 5 and is connected to the mounting rod 11. Another second fixing bolt 6 passes through the connecting block 5 and is connected to another mounting rod 11. The cooperation between the connecting block 5 and the second fixing bolt 6 can further enhance the connection stability between the mounting rods 11. When the auxiliary device 1 is working, each mounting rod 11 needs to jointly bear the force generated by the motor 12, the double-acting screw 13, and other components. By connecting adjacent mounting rods 11 together through the connecting block 5 and fastening them with the second fixing bolt 6, relative displacement or loosening between the mounting rods 11 can be effectively avoided, thereby ensuring the structural integrity of the entire auxiliary device 1 during operation. At the same time, this connection method also facilitates the disassembly and replacement of the mounting rods 11 when needed, improving the maintenance efficiency of the device.

[0031] In summary, the tire bead auxiliary device for all-steel radial tire installation described in this utility model, through the setting of the buffer mechanism 2, the buffer pressure head 24 and the spring 21 during the tire bead opening process, can effectively reduce the impact force on the tire bead, avoid damage to the internal structure of the tire bead due to excessive instantaneous force, and improve the stability and safety of tire bead installation. At the same time, the setting of the flexible protective sleeve 26 further protects the wheel hub from damage during installation, extends the service life of the wheel hub, and improves the overall quality of tire installation. In addition, the setting of the rubber buffer head 4 effectively avoids direct hard collision between the output end of the first cylinder 17 and the wheel hub when the installed tire assembly is ejected, reducing the risk of wheel hub damage and ensuring the safety of the installation process.
