В современном производстве дронов, шарнир шасси, хотя и небольшой по размеру, является важнейшим несущим компонентом.. It absorbs impact during takeoff and landing while connecting the fuselage to the landing system.
With over 15 years of CNC machining process experience, we have seen numerous failure cases caused by insufficient strength, as well as folding mechanism issues resulting from tolerance deviations.
Drone landing gear joints are typically machined from 7075-T6 or 6061 алюминиевые сплавы, requiring a balance between maximum strength and minimum weight.
В этой статье, we provide an in-depth analysis of four key areas:
- Выбор материала
- 5-axis machining strategies
- Deformation control of thin-walled structures
- Обработка поверхности
Выбор материала: Controlling Quality from the Source
Material selection is often underestimated, yet it directly determines the final product performance.
When machining 7075-T6 aluminum, many manufacturers encounter issues such as surface mottling or black spots after anodizing. These defects are not merely cosmetic—they indicate non-uniform internal microstructure.
В Быстроэффективный, we address this at the source:
- We collaborate directly with certified material suppliers
- High-purity aluminum stock is custom-ordered
- Trial anodizing is conducted before full production
This ensures consistent grain structure and stable anodizing performance across batches.
Such strict material control forms the foundation for landing gear joints capable of withstanding thousands of impact cycles.
Thin-Walled Structure Machining: Управление деформацией
To reduce weight and increase flight endurance, landing gear joints often feature complex thin-walled rib structures.
The main challenge lies in stress-release deformation.
Using conventional machining methods, parts may deform by more than 0.05 мм after unclamping—leading to assembly failure.
Our Process Strategy
We implement a controlled process:
- Черновая обработка
- Natural aging or stress-relief treatment
- Финишная обработка
Кроме того, our engineering team provides ДФМ (Дизайн для технологичности) feedback, включая:
- Optimizing internal fillet radii
- Reducing uneven cutting forces
- Improving structural stability
This allows us to maintain tight tolerances within ±0,01 мм.
5-Axis Machining Strategy: Точность и эффективность
Complex geometries such as angled surfaces and irregular holes present significant challenges.
Traditional 3-axis machining requires multiple setups, with each setup introducing cumulative errors of approximately 0.02 мм.
Advanced Machining Approach
By utilizing 3+2 positioning and full 5-axis machining, we can:
- Complete multi-surface machining in a single setup
- Improve efficiency by over 15%
- Ensure coaxiality between mounting holes and pivot holes
For customers, this translates into:
- Smoother folding mechanisms
- Improved durability
- Longer product lifecycle
Our production capability includes:
- 20+ обрабатывающие центры с ЧПУ
- 10+ turn-mill machines
This supports both prototyping and high-volume production.
Tooling Strategy: Maximizing Surface Quality
Tool selection plays a critical role in machining high-strength aluminum alloys.
We avoid standard HSS tools and instead use:
- High-hardness coated carbide tools
- Tools optimized specifically for aluminum machining
Преимущества
- Excellent chip evacuation
- Reduced built-up edge formation
- Surface finish up to Ра 0.8 или лучше
Оптимизация процесса
Our engineers continuously optimize:
- Скорость подачи
- Spindle speed
- Toolpath strategies
The goal is to:
- Reduce cycle time
- Improve yield rate
- Maintain consistent quality
Контроль качества: Process-Based Assurance
Final inspection alone is not sufficient for precision components.
В Быстроэффективный, quality control is integrated throughout the entire process.
IPQC System
- First-piece inspection every 2 часы
- Real-time monitoring of critical dimensions
Inspection Equipment
- ШМ (Координатно-измерительная машина)
- Cylindricity testers
Material Verification
For critical or overseas projects, мы используем:
- Handheld XRF analyzers
This ensures:
- Accurate material composition
- Elimination of material mix-up risks
Обработка поверхности: Managing Critical Tolerances
Surface treatment is the final but crucial step.
Landing gear joints typically require hard anodizing to improve wear resistance.
Key Challenge
Hard anodizing causes dimensional growth of:
- 0.008–0,012 мм
Failure to compensate for this often results in assembly issues.
Our Solution
- Precise anodizing allowance planning
- Collaboration with specialized surface treatment partners
- Controlled finishing processes
Защита поверхности
To prevent damage such as scratches or dents:
- Custom blister trays are used for transportation
- Strict handling procedures are implemented
This ensures parts remain in optimal condition upon delivery.
