Description

Technical Field

[0001] This utility model relates to the field of orthopedic positioning tooling technology, and in particular to an orthopedic positioning tooling for a side trim piece of a car tailgate. Background Technology

[0002] In the automotive body manufacturing industry, the tailgate side trim, as a key component of the vehicle's exterior, serves multiple functions: it not only constitutes an important visual transition area between the side panel and the tailgate, directly affecting the overall appearance and gap uniformity, but also has practical functions such as protecting the internal structure and guiding rainwater. These trim pieces are typically made of composite materials or sheet metal, and their manufacturing and assembly quality directly determines 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 trim faces a series of manufacturing challenges: First, at the material level, the composite inner panel and metal frame are prone to residual stress release during injection molding or stamping, leading to deformation later; second, during transportation and storage, the trim often warps irregularly due to stacking pressure or temperature changes; finally, in the assembly stage, the trim needs to achieve millimeter-level precision matching with the tailgate sheet metal and side panel structure, and any slight shape deviation will lead to appearance defects such as uneven gaps and excessive step deviations. If these deformation issues are not corrected before assembly, they will directly cause defects in the overall vehicle appearance quality and may lead to functional failures such as wind noise and water leakage.

[0003] Currently, existing orthopedic positioning devices suffer from unstable clamping when holding automotive tailgate side trim pieces. Due to their unreasonable structural design, they cannot effectively adapt to changes in the shape and size of automotive tailgate side trim pieces, resulting in insufficient or uneven clamping force during the orthopedic process. This makes the trim pieces prone to displacement or deformation under stress, affecting the orthopedic effect. Utility Model Content

[0004] The purpose of this utility model is to provide a corrective positioning fixture for the side trim of a car tailgate, which aims to solve the problem of unstable clamping of the existing corrective positioning device when clamping the side trim of the car tailgate.
