Description

Technical Field

[0001] This utility model relates to the field of door panel processing fixtures, and in particular to a door panel assembly fixture. Background Technology

[0002] As a crucial component of automotive interiors, the processing quality and efficiency of T28 door trim panels directly impact the overall vehicle quality and production costs. TOM (Total Material Manufacturing) technology, or 3D surface decoration technology, is an advanced out-of-mold decoration technique. Through heating and vacuum pressurization, a thin film of interior trim is wrapped around the surface of a 3D-shaped component. This technology can achieve various appearance effects such as wood grain, electroplating, high gloss, carbon fiber, and aluminum imitations, significantly enhancing the aesthetics and texture of automotive interiors. Door trim panels are generally divided into front door trim panels and rear door trim panels, such as... Figure 1 The image shows the rear door trim panel, which has a protrusion on one side for mounting and positioning. The front door trim panel is similar but has a different shape.

[0003] In the processing of T28 door trim panels, jigs play a crucial role. They are auxiliary tools used to position and support the workpiece during processing, ensuring machining accuracy and quality. For TOM machine forming, jig design must meet the requirements of high precision, high stability, and ease of operation. However, most T28 door trim panel processing jigs widely used in the market currently adopt an integral design, which cannot be flexibly spliced ​​into segments. This design limits the adaptability and flexibility of the jig, making it impossible to quickly adjust and optimize it according to different door trim panel models. Furthermore, the complex structure and high processing difficulty of integral jigs significantly increase CNC machining time, which not only increases production costs but also reduces production efficiency. Moreover, existing jigs cannot be used in multiple machine models; if the machine is occupied by other projects, it will lead to production stoppage, affecting the execution of production plans and potentially causing delivery delays.

[0004] Therefore, it is necessary to propose a door panel assembly fixture to solve the above problems. Utility Model Content
