Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic positioning tooling, and in particular to an orthopedic positioning tooling and method for automobile tailgate side decorations. Background Art

[0002] In the automotive body manufacturing industry, tailgate side trims, as a key component of the vehicle's exterior, fulfill multiple functions. They not only form a crucial visual transition zone between the body side and tailgate, directly impacting the overall vehicle's appearance and gap uniformity, but also serve practical functions such as protecting the internal structure and diverting rainwater. These trims are typically made of composite materials or sheet metal, and their manufacturing and assembly quality directly impact key quality indicators such as gap uniformity, step consistency, and streamlined appearance in the tailgate area. However, in the actual automotive manufacturing process, tailgate side trims face a number of manufacturing challenges. First, at the material level, the composite inner panel and metal frame are prone to residual stress release during the injection molding or stamping process, leading to deformation later in the process. Second, during transportation and storage, the trims often warp irregularly due to stacking pressure or temperature fluctuations. Finally, during assembly, the trims must be aligned with the tailgate sheet metal and side panel structure to millimeter-level precision. Any slight shape deviation will result in cosmetic defects such as uneven gaps and excessive step differences. If these deformation problems are not corrected before assembly, they will directly cause defects in the appearance quality of the entire vehicle and may cause functional failures such as wind noise and water leakage.

[0003] Currently, existing orthopedic positioning devices suffer from unstable clamping when clamping tailgate trims. Due to their irrational structural design, they are unable to effectively adapt to the shape and size changes of tailgate trims. This results in insufficient or uneven clamping force during the orthopedic process, making the trims prone to displacement or deformation when subjected to force, affecting the orthopedic effect. Summary of the Invention

[0004] The object of the present invention is to provide a corrective positioning tool and method for a car tailgate side trim, aiming to solve the problem of unstable clamping of the existing corrective positioning device when clamping the car tailgate side trim.
