High-Precision Automation Positioning Engineering
Multi-step staggered positioning groove profile realizes multi-spec product synchronous clamping and positioning on one fixture block, supporting batch automated feeding and positioning operations. Split double-layer sliding fit structure reserves controlled clearance for linear reciprocating movement, avoiding jamming during high-speed automated cycling. Evenly distributed counterbore mounting holes adopt ultra-tight positional tolerance, enabling fast, repeatable fixture installation on robot platforms and equipment frames.
Integrated thickened main beam structure delivers high bending rigidity, eliminating positioning offset caused by repeated clamping impact during long-term continuous automated production.
Customizable Material Performance for Automation Scenarios
Two mainstream material options match different automation production demands:
- 6061-T6 Aluminum Alloy Variant: Low density reduces overall fixture load for robotic arms; excellent thermal conductivity dissipates friction heat during high-speed sliding; hard anodizing boosts surface wear resistance for light-load automation assembly lines
- S136 Stainless Steel Variant: High hardness and anti-corrosion performance, suitable for heavy-load stamping automation, humid workshop and chemical contact production environments, resisting abrasion from metal workpiece friction Both materials feature superior CNC machinability for complex multi-groove stepped profiles, stable dimensional consistency under frequent temperature fluctuations of automated equipment.
Custom Automation Fixture Engineering Support
- Custom overall length, multi-step positioning groove shape, sliding clearance and mounting hole layout based on customer automation equipment 2D/3D CAD drawings
- Optional surface upgrades: Hard Anodizing, DLC Anti-Friction Coating, Precision Surface Grinding, Passivation
- DFM fixture consultation: positioning tolerance optimization, sliding gap matching, robot load balance design
- Fast prototype fixture sampling and mass batch production delivery for automated line upgrading projects
Key Features & Advantages
- Multi-Groove Multi-Station Design: Integrated staggered positioning grooves support simultaneous clamping of multiple workpieces to improve automated line throughput.
- Split Double-Layer Sliding Structure: Precisely controlled fit clearance ensures smooth reciprocating linear motion without jitter or jamming.
