A screw turner is a key checking fixture in automotive manufacturing and quality control, primarily used to quickly and accurately inspect the size, position, and fit of various body-in-white (BIW) components, ensuring production consistency and improving product quality.
It is used to verify that critical dimensions of stamped and welded parts meet design requirements, preventing assembly problems caused by dimensional deviations. It can be used to inspect the hole position and contour dimensions of panels such as doors, hoods, and bumpers.
In automotive manufacturing, the gap and flush of various components (such as doors and bodies, front and rear bumpers and fenders) must comply with DTS (Dimensional Technical Specification) standards.
PCF checking fixtures simulate actual assembly conditions, quickly verifying the fit between components and preventing uneven gaps or interference after assembly.
