Body Fixture / Carrier for Motor Vehicle Manufacturing

Product Specifications

Technical details and manufacturing context for Body Fixture / Carrier

Definition

A Body Fixture / Carrier is a precision-engineered component used in motor vehicle manufacturing to securely hold and position vehicle body shells or frames at interior assembly stations. It provides stable support and precise alignment for installing interior components such as seats, dashboards, trim panels, wiring harnesses, and other interior elements, ensuring proper fit and assembly quality. The fixture/carrier typically uses mechanical clamps, vacuum systems, or hydraulic/pneumatic actuators to grip the vehicle body at designated structural points. It may include adjustable positioning mechanisms to accommodate different vehicle models or configurations. The carrier often moves along assembly lines or rotates to provide optimal access for assembly workers or robots to install interior components efficiently. Key parameters include load capacity (500–2000 kg), positioning accuracy (±0.1–±0.5 mm per ISO 230-2), repeatability (±0.05–±0.2 mm per ISO 230-2), operating temperature (-10–60 °C), operating pressure (0.4–0.8 MPa), electrical supply (24 V DC ±10% per IEC 61131-2), ingress protection (IP54–IP65 per IEC 60529), material grade (Q235–Q345 per GB/T 700), surface treatment (zinc plating 8–12 μm per ASTM B633), and weight (300–1500 kg). Materials on file include high-strength steel and aluminum alloy. These values are reference ranges; verify model-specific specifications with the legal manufacturer or supplier before procurement.

Working Principle

The fixture/carrier secures the vehicle body using mechanical clamps, vacuum systems, or hydraulic/pneumatic actuators at designated structural points. Adjustable positioning mechanisms allow accommodation of different vehicle models. The carrier may move along assembly lines or rotate to provide optimal access for workers or robots. This ensures stable support and precise alignment for interior component installation, maintaining assembly quality and efficiency.
