[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] A wheel alignment device is designed with the core goal of improving wheel alignment accuracy and ease of operation. The design philosophy of this device is to ensure efficient and accurate wheel alignment through precise engineering and carefully selected materials. The device consists of several key components, each with a specific function, working together to achieve precise wheel alignment.

[0020] As the core component of the device, guide rail 2 plays a crucial role. Mounted directly on base 1, it provides a precise guide path for wheel alignment. Guide rail 2 must be precisely designed to ensure the wheel moves smoothly and stably along the intended trajectory during alignment. This requires not only sufficient strength to support the weight of the wheel but also sufficient durability to withstand the various forces generated during alignment, such as friction and pressure. The surface treatment of guide rail 2 is also crucial to ensure a low coefficient of friction and a long service life.

[0021] The material selection for the guide rail 2 requires consideration of rigidity, wear resistance, and deformation resistance. High-strength steel or alloy steel is typically chosen, as these materials provide the required rigidity and durability while also withstanding the stresses that may occur during repeated use. Furthermore, the surface of the guide rail 2 can be treated with special treatments, such as chrome plating or application of a wear-resistant coating, to further enhance its wear and corrosion resistance.

[0022] To ensure precise guidance of the guide rail 2, the design of the base 1 is also crucial. It needs to have sufficient stability and load-bearing capacity to support the weight of the guide rail 2 and the wheel. The base 1 is typically constructed of sturdy cast iron or heavy-duty steel, which not only provides the necessary rigidity and stability but also withstands the vibrations and shocks generated during the wheel alignment process.

[0023] Beneath base 1, a pressure cylinder 12 is located. Its function is to apply the necessary pressure during the alignment process to ensure close contact between the wheel and the device. The design of pressure cylinder 12 must take into account the required pressure range and stability to ensure consistent pressure output under different operating conditions.

[0024] The fixed block 11 is located inside the base 1. Its function is to connect and support other components, such as the upper hold-down guide bearing 10 and the side hold-down guide bearing 9. The design of these bearings must take into account the stability and pressure they need to provide during the alignment process. The upper hold-down guide bearing 10 is connected to the inner side of the fixed block 11, which is closer to the rack 5, while the side hold-down guide bearing 9 is connected to the side of the fixed block 11. The material selection of these bearings must take into account wear resistance and pressure resistance to ensure that they can maintain good performance during long-term use.

[0025] The guide rail 2 is also equipped with a slider 13, which can slide freely on the guide rail to accommodate the centering movement of the wheel. The design of the slider 13 needs to take into account the smoothness of sliding and wear resistance to ensure that accurate alignment is maintained during long-term use. A fixed seat 4 is connected above the slider 13. This fixed seat is used to fix the slider and ensure its stable sliding on the guide rail. The design of the fixed seat 4 needs to take into account the coordination with the slider 13 to ensure stability and accuracy during the sliding process.

[0026] Positioning column 3 is a crucial component of the wheel alignment system. It is strategically placed within the gap between the rollers. This placement allows for direct contact between the column and the wheel, providing a necessary positioning reference. During the alignment process, positioning column 3 helps precisely position the wheel in the center of the assembly line, which is crucial for ensuring accurate wheel stacking and handling in subsequent operations.

[0027] The design of the locating stud (3) requires careful consideration to ensure it perfectly matches the wheel's geometry and dimensions. This typically involves precise measurement and analysis of the wheel's dimensions to design the appropriate locating stud (3) size and shape. The diameter, length, and surface treatment of the locating stud (3) all need to account for the contact area and force with the wheel to ensure the wheel does not slip or deflect during alignment.

[0028] The surface treatment of the locating post 3 is also an important consideration. To reduce friction and wear, the surface of the locating post 3 may be hardened or coated with a special lubricant. Furthermore, the surface of the locating post 3 can be designed with a specific texture or pattern to increase friction with the wheel and prevent slippage during alignment.

[0029] Mounting bracket 4 provides a secure support for locating column 3, ensuring its stability during the alignment process. The design of mounting bracket 4 requires consideration of its connection to locating column 3 and the precise placement of locating column 3 within the gap in the assembly line. Mounting bracket 4 may employ a rigid structural design to ensure it does not deform due to pressure during wheel alignment.

[0030] In practice, the position and angle of the locating column 3 may require fine-tuning to accommodate minor variations in the production line and the specific characteristics of different wheels. This fine-tuning capability is a key feature of the device design, ensuring that it can flexibly adapt to different operating conditions and maintain efficient alignment performance.

[0031] In summary, the locating column 3 is a crucial component of the wheel alignment system. Its design and placement are crucial to ensuring precise wheel alignment on the assembly line. Through careful design and manufacturing, the locating column 3 can improve the overall performance of the wheel alignment system, meet the requirements of high-precision wheel alignment, and ensure accurate wheel handling in subsequent processes.

[0032] The guide rails 2 are symmetrically placed on the base 1. This design helps ensure balance and stability during the wheel alignment process. The symmetrical design also helps to distribute the forces the device is subjected to during operation, thereby improving the durability of the device.

[0033] Connecting bases 8 are provided on both sides below the base 1 for fixing the device to the ground or other supporting structures. The design of the connecting bases 8 needs to take into account the compatibility with the ground or other supporting structures to ensure the stability of the device during use.

[0034] The base 1 serves as the supporting structure for the wheel alignment system. It must be robust enough to support the weight of the system and the forces generated during operation. It is typically constructed from high-strength materials such as cast iron or steel, known for their excellent load-bearing capacity and durability. The structural design of the base 1 must take into account weight distribution, contact area, and mechanical principles to ensure it withstands heavy pressure and impact without deformation or damage.

[0035] The base 1 is provided with slotted fixing holes 7 on either side. These slotted holes are a key feature of the device's design. They not only secure the device but also allow for adjustment of its position as needed. This adjustability allows the device to accommodate wheels of varying sizes, enhancing its versatility and flexibility. The slotted fixing holes 7 require precise design to ensure stability and repeatable positioning during adjustments.

[0036] The pressure cylinder 12 is another key component of the device and is located below the base 1. The main function of the pressure cylinder 12 is to apply the necessary pressure during the alignment process to ensure close contact between the wheel and the device. This close contact is crucial to improving alignment accuracy, as any slippage or looseness can lead to inaccurate alignment and affect the quality of wheel positioning. The design of the pressure cylinder 12 needs to take into account the required pressure range, stability, and durability to ensure consistent pressure output under different operating conditions. The pressure cylinder can be a pneumatic or hydraulic device.

[0037] The fixing block 11 is located inside the base 1. Its primary function is to connect and support other components, such as the upper pressure guide bearing 10 and the side pressure guide bearing 9. The design of the fixing block 11 must take into account its load-bearing capacity and stability to ensure the stability of the entire device during operation. The fixing block 11 is typically made of a sturdy material to ensure that it can withstand the forces from the pressure cylinder 12 and other components. In addition, the surface of the fixing block 11 may undergo special treatment, such as plating or coating, to improve its corrosion and wear resistance.

[0038] The geometry and dimensions of the fixing block 11 must be precisely calculated based on the size and weight of the components it supports. It must provide sufficient contact area to distribute forces, reducing localized stress concentrations and thus improving the durability and reliability of the entire device. The fixing block 11 may also contain grooves or threaded holes for positioning and securing other components. These features must be precisely manufactured to ensure proper installation and alignment of the components.

[0039] The upper clamping guide bearing 10 and the side clamping guide bearing 9 are key components in the wheel centering device. They are responsible for providing the necessary pressure during the centering process to ensure the stability and precise positioning of the wheel. The upper clamping guide bearing 10 is mounted on the fixed block 11 and is specifically designed to be connected to the inner side of the fixed block 11 toward the rack 5. This design enables the upper clamping guide bearing 10 to directly apply pressure to the upper part of the rack 5 to achieve stable and precise positioning. The precise position and structural design of the upper clamping guide bearing 10 are crucial to ensure that the rack does not move unnecessarily during the centering process.

[0040] The side pressure guide bearing 9 is also mounted on the fixed block 11, but it is connected to one side of the fixed block 11 and is used to apply horizontal pressure to the outside of the rack 5. The design of the side pressure guide bearing 9 needs to take into account the lateral forces it will need to withstand during the alignment process, so it must be sufficiently strong to resist possible deviation or deformation. The side pressure guide bearing 9 is used to ensure the horizontal centering of the rack and works in conjunction with the upper pressure guide bearing 10 to improve the alignment accuracy of the entire device.

[0041] Both bearings need to be selected and designed with wear resistance and durability in mind to ensure they maintain their performance over time and repeated use. The bearings may be made of high-strength steel or alloys that provide the required strength and durability while also withstanding the continuous pressure generated by the alignment process.

[0042] Slider 13 is another important component in the system. It is mounted on guide rail 2 and can slide freely on it to accommodate the wheel centering movement. The design of slider 13 needs to take into account smooth sliding and wear resistance, which are key factors in ensuring accurate alignment during long-term use. Slider 13 may be made of low-friction materials such as bronze or special plastics. These materials can reduce friction with guide rail 2 while maintaining strength.

[0043] To further enhance the wear resistance and stability of the slider 13, its surface may undergo special treatment, such as plating or application of a wear-resistant coating. Furthermore, the structural design of the slider 13 must ensure smooth movement on the guide rail 2, maintaining consistent performance regardless of operating conditions. The size and shape of the slider 13 must also precisely match the guide rail 2 to ensure that it does not become stuck or deviate from the intended trajectory during alignment.

[0044] Correct positioning of the slider 13 on the guide rail 2 is crucial to the entire wheel alignment process. It not only needs to slide freely on the guide rail 2 but also provide stable support during wheel alignment. The slider 13 must be precisely designed and manufactured to ensure smooth and accurate movement on the guide rail 2, which is crucial for achieving precise wheel alignment.

[0045] The fixed seat 4 is a key component in the device, located above the slider 13. Its design is crucial because its primary function is to secure the slider 13 and ensure its stable sliding on the guide rail 2. The fixed seat 4 must provide sufficient support to prevent the slider 13 from vibrating or shifting during movement. To achieve this goal, the design of the fixed seat 4 requires careful consideration of its fit with the slider 13, including their contact area, alignment, and fixing method. This fit must be precise to ensure stability and accuracy during sliding, thereby ensuring the accuracy of the wheel alignment process.

[0046] The fixing base 4 is typically made of a high-strength material to ensure it can withstand the forces generated by the movement of the slider 13. Furthermore, the surface of the fixing base 4 may be specially treated, such as with a plating or coating, to enhance its wear and corrosion resistance. The structural design of the fixing base 4 also needs to consider ease of installation and maintenance, so that the slider 13 can be quickly replaced or adjusted when necessary.

[0047] Positioning column 3, located above mounting base 4, provides an additional reference for positioning during wheel alignment. The design of positioning column 3 must be tailored to the wheel's position to ensure accurate positioning during alignment. Positioning column 3 is adjustable to accommodate wheels of varying sizes, ensuring precise positioning during alignment. The material selection for positioning column 3 also needs to consider wear resistance and strength to ensure accuracy and reliability over extended use.

[0048] The symmetrical placement of the guide rails 2 on the base 1 is an innovative feature of the device's design, helping to ensure balance and stability during wheel alignment. This symmetrical design means the guide rails 2 are evenly distributed across the base 1, ensuring uniform forces applied to the wheel during alignment, thereby improving the stability and accuracy of the process. Furthermore, the symmetrical design helps to distribute the forces experienced by the device during operation, reducing stress concentrations on individual components and thereby increasing the durability and service life of the device.

[0049] The design and manufacture of the guide rails 2 require precision and rigidity to ensure they remain stable under the weight of the sliders 13 and wheels. The guide rails 2 may be constructed from high-strength steel or alloys, which not only provide the required strength and rigidity but also withstand repeated use over time. The surface of the guide rails 2 may be precision machined to ensure smooth movement of the sliders 13, minimizing friction and wear.

[0050] In summary, the fixing base 4, locating column 3, and guide rail 2 are key components of the wheel alignment system. Their design and manufacture require comprehensive consideration of material selection, mechanical properties, machining accuracy, and surface treatment. Through careful design and manufacturing, these components can enhance the overall performance of the wheel alignment system, meet the requirements of high-precision wheel alignment, and ensure long-term, reliable operation under various operating conditions.

[0051] The connection base 8 is located on both sides below the base 1 and is used to fix the device to the ground or other supporting structures. The design of the connection base 8 needs to take into account the compatibility with the ground or other supporting structures to ensure the stability of the device during use.
