[0051] Please refer to Figure 8 In this embodiment of the present invention, optionally, the gear assembly 7.3 includes: a gear 7.3.1 and a rack frame 7.3.2, the gear 7.3.1 is connected to the shaft assembly 7.2, and the rack frame 7.3.2 is connected to the fourth hydraulic cylinder 7.4; the rack on the rack frame 7.3.2 and the gear 7.3.1 are meshed together.

[0052] In this embodiment of the invention, a stable support platform is formed by setting up a frame structure 1, which effectively supports other components and ensures the stability and durability of the overall structure. The tire trolley 11 set on the frame base plate 1.1 carries the tire to be disassembled, improving the stability of the structure. The chuck arm component 2 is used to fix the wheel hub with the tire to be disassembled. The cooperation between the hydraulic power system 3 and the hydraulic control system 5 enables precise control of the operation of the tire disassembly head structure 7 and provides strong disassembly and assembly force, ensuring the safety and accuracy of the tire disassembly and assembly process and avoiding errors caused by human operation. The precise control of the tire disassembly head structure 7 is achieved through the cooperation of the first cylinder 4 and the second cylinder 6. The tire disassembly head structure 7 is installed on the guide rail 1.6, which enables it to have good guidance and range of motion in the tire disassembly operation, improving the accuracy and efficiency of tire disassembly. The tire trolley 11 is connected to the tire disassembly head structure 7 to facilitate the handling and replacement of tires. Through mechanization and hydraulic drive, the physical labor in the manual disassembly and assembly process is greatly reduced, the work efficiency is improved, the labor intensity of the operators is reduced, and the work comfort is improved.

[0053] The specific working process is as follows: The operator places the tire to be removed onto the tire trolley 11, and uses the chuck rotating arm component 2 to fix the tire to be removed in a suitable position through the control of the hydraulic system. Through the control panel of the hydraulic control system 5, the hydraulic power system 3 is activated. The first oil cylinder 4 and the second oil cylinder 6 cooperate with each other to drive the tire removal head structure 7 to contact the tire to be removed and complete the tire removal process by pressing down and rotating.

[0054] In this embodiment of the invention, the tire removal head assembly 7.1 includes a tire pressure plate and a tire removal hook, which are connected to the shaft assembly 7.2. The tire pressure plate is primarily used to firmly press the tire down during removal and installation, ensuring the contact surface between the tire and the rim is fixed, thereby preventing the tire from slipping or shifting during removal and installation, increasing the accuracy and safety of the process. Furthermore, during tire removal, the tire pressure plate provides a stable force application surface. When the tire removal hook pries the tire away from the rim, the pressure applied by the tire pressure plate helps guide the tire's detachment, reducing damage to the tire and its materials. Effective clamping shortens tire removal and assembly time, reduces the extra force required by operators, and makes the process easier and more efficient. The tire removal hook is primarily used to pry open the connection between the tire and rim, aiding in tire separation. Its shape allows it to effectively embed into the tire-rim seam, facilitating easy tire removal. The hook provides better grip and control, allowing operators to more flexibly adjust the angle and force of the removal, enhancing the overall controllability of the tire removal operation. The connection between the tire clamping plate and the tire removal hook to the axle assembly 7.2 enables them to work together. As the tire clamping plate presses down, the tire removal hook can quickly insert, forming a well-defined removal strategy that ensures the coordination and smoothness of the entire process.

[0055] In this embodiment of the utility model, the gear assembly 7.3 is connected to the rack and gear 7.3.1 on the rack frame 7.3.2 through meshing, so as to realize a simple rotation action to change the working direction of the pressure plate and the tire removal hook, so that the operator does not need to manually fine adjust the position of the pressure plate and the tire removal hook, thus improving work efficiency.

[0056] In this embodiment of the utility model, optionally, it also includes:

[0057] The frame structure also includes a first bushing 1.7 and a second bushing 1.8; the first support 1.2 includes a vertical frame and a horizontal frame;

[0058] The first bushing 1.7 is mounted on the upright of the first bracket 1.2, and the chuck rotating arm component 2 is fitted onto the upright of the first bracket 1.2 via the first pin 8 and the first bushing; the second bushing is mounted on the crossbar of the first bracket 1.2, and the second end of the first oil cylinder 4 is fitted onto the crossbar of the first bracket 1.2 via the third pin 10 and the second bushing.

[0059] Please refer to Figure 2 In this embodiment of the invention, the connection strength between the chuck arm component 2 and the first bracket 1.2 is enhanced by setting the first bushing 1.7 and the second bushing 1.8. This allows the load and vibration of the chuck arm component 2 during operation to be effectively dispersed, reducing the risk of structural damage and ensuring the stability and safety of tire removal operations. The first bushing 1.7, mounted on the upright of the first bracket 1.2, allows the chuck arm component 2 to rotate and move flexibly via the first pin 8, enabling precise position adjustment during tire removal to accommodate different tire sizes and improve the flexibility and efficiency of tire removal and installation. Furthermore, the second bushing 1.8, located on the crossbar of the first bracket 1.2, provides additional support and connection points for the second end of the first cylinder 4. Assembled via the third pin 10, it ensures the cylinder maintains a stable position during operation, enhancing its force transmission effect during the pushing and pulling process, thereby improving the overall working efficiency of the hydraulic system.

The claw assembly 2.1 is connected to the chuck assembly 2.2, allowing it to open and close flexibly, thereby efficiently gripping and releasing the tire and ensuring rapid adaptation to different tire shapes and sizes during assembly and disassembly. Please refer to... Figure 5The connection between the chuck assembly 2.2 and the external gear 2.6 and internal gear 2.7 forms a good power transmission system. The hydraulic motor 2.3 drives the external gear 2.6 to rotate, which in turn drives the internal gear 2.7 to rotate, realizing fine adjustment and synchronous movement between the gears. The meshing connection improves the rotational accuracy and increases the efficiency of tire removal operations. The connection between the external gear 2.7 and the hydraulic motor 2.3 ensures that the power output of the motor can be transmitted to the claw assembly 2.1 through the gear system, providing smooth and powerful rotational power. The robotic arm 2.4 is assembled with the first support 1.2 of the frame through the first pin 8, providing a stable support base. During the disassembly and assembly process, the robotic arm can provide accurate positioning and height adjustment to adapt to different tire disassembly requirements. The third hydraulic cylinder 2.5 passes through the chuck assembly 2.2 and the claw assembly 2.1, so that the cylinder can not only be used for horizontal movement, but also realize the control of vertical movement, enhancing the stability and accuracy of the gripping process, helping to prevent the tire from slipping during the disassembly and assembly process, and improving the safety and efficiency of the disassembly and assembly process.

The connecting plate 2.1.2 is hinged between the jaw 2.1.1 and the chuck assembly 2.2 by a pin, realizing flexible linkage between the jaw and the chuck, allowing the jaw to open and close freely, improving operational flexibility. The connection between the third end of the connecting plate 2.1.2 and the roller shaft 2.1.4, which is assembled in the chuck assembly 2.2, provides a stable motion platform for the jaw 2.1.1, giving the jaw good support and positioning capabilities when opening and closing. The pull rod 2.1.3 is set inside the two connecting plates 2.1.2, optimizing the force transmission structure. The first end of the pull rod is connected to the jaw 2.1.1, and the second end is connected to the chuck assembly 2.2, ensuring that the action and force can be efficiently transmitted from the hydraulic system or other drive source to the jaw 2.1.1 during operation, improving overall work efficiency.

[0070] Please refer to Figure 6 In this embodiment of the present invention, the chuck assembly optionally includes: a chuck base 2.2.1, a cross disc 2.2.2, a nut 2.2.3, and a pusher 2.2.4;

Figure 9 The grooved assembly design between the slider 7.12 and the guide rail 1.6 ensures smooth sliding of the tire removal head during movement, providing good guiding ability and making the entire disassembly and assembly process more precise and stable.

[0074] In this embodiment of the utility model, the specific usage process of the car tire changing and mounting machine is as follows:

[0075] First, the operator uses a forklift or other equipment to place the tire to be removed on the tire trolley 11, which is then operated through the hydraulic control system 5.

[0076] Oil is introduced into the right end of the second cylinder 6 to control the tire to be removed on the tire trolley 11 to move to a suitable position near the chuck arm component 2 to ensure docking accuracy.

[0077] Oil is introduced into the rear end of the third cylinder 2.5 to open the chuck 2.1.1 and support it on the inner circumference of the wheel hub, ensuring that the tire will not move or slip during the following operation; then oil is introduced into the lower end of the first cylinder 4 to raise the tire to be removed to a suitable height.

[0078] Oil is introduced into the left end of the fourth cylinder 7.4, causing the disassembly head assembly 7.1 to rotate 180 degrees around the axial direction of the shaft assembly 7.2, so that the pressure plate of the disassembly head assembly 7.1 is turned towards the tire bead, in preparation for subsequent disassembly.
