Precision 6061 Dual-Adjustable Locating Fixture with Black Anodizing for 3C Automation

We manufactured a precision 6061 aluminum dual-adjustable locating fixture for a 3C electronics automation assembly line. This fixture features two independent adjustable slides with screw-driven mechanisms that control travel distance and parallelism — enabling precise dual-side datum positioning for component alignment in automated assembly. The fixture design combines high structural rigidity with fine adjustment capability, critical for maintaining repeatable positioning accuracy in 3C production environments.

The manufacturing process integrated precision milling, sub-assembly fabrication, and final assembly with functional verification. Each slide wAs Machined to tight tolerances with guide surfaces held to specified flatness and parallelism. Adjustment screws were precision-threaded with controlled pitch to achieve the required resolution for stroke adjustment. All components were black anodized (MIL-A-8625 Type II) for wear resistance and a professional uniform appearance. Post-assembly verification confirmed travel range, parallelism between slides, and positioning repeatability within specified limits.

Project Overview

Key Technical Highlights

• Dual-Slide Independent Adjustment: Two independent slides with screw-driven mechanisms enable individual travel and parallelism adjustment — providing flexible datum positioning for varying component geometries in 3C assembly.
• Precision Guide Surface Machining: Slide guide surfaces and locating datums machined to specified flatness and parallelism tolerances — ensuring smooth slide movement and consistent positioning accuracy.
• Threaded Adjustment Precision: Adjustment screws machined with controlled thread pitch to achieve the required stroke resolution, with locking mechanisms to maintain set positions during operation.
• Black Anodized Finish: Type II black anodizing provides uniform wear resistance, corrosion protection, and non-reflective surface — suitable for automated production environments.

Quality Verification

CMM inspection verified locating surface dimensional accuracy (±0.02mm) and guide feature flatness. Slide travel range and parallelism verified through functional testing with measurement tools. Thread engagement and adjustment resolution confirmed per specification. Anodized coating inspected for uniformity and coverage.

Industry Applications

Ideal for 3C automation assembly fixtures, dual-side locating systems, adjustable component positioning tooling, and precision production line alignment applications.
