The mobility and performance of special robots heavily rely on the precision of their key components - like the swing arm suspension axle. Acting as the robot's "motion joint", this suspension axle, machined from high-quality aluminum alloy via precision CNC machining, ensures stable and reliable operation in demanding environments such as explosion-proof, rescue, and aerospace applications.
Its core value lies in providing robots with extremely high motion accuracy, exceptional load capacity, and outstanding environmental adaptability, making it an indispensable key component in high-end equipment manufacturing.
Product Description
This Swing Arm Suspension Axle is a core motion component specifically designed for special robots (including explosion-proof, rescue, aerospace, etc.).
It is manufactured from high-strength 7075 aluminum alloy, precisely milled by 5-axis CNC machining centers, and undergoes T6 heat treatment and hard anodizing. Finally, it is strictly inspected by a CMM (Coordinate Measuring Machine) to ensure high dimensional stability, excellent wear and corrosion resistance, and superior fatigue strength.
This component is primarily used to achieve flexible swinging motion and precise positioning for the robot body, effectively absorbing shocks and vibrations from complex terrains. It is key to enhancing the robot's environmental adaptability and motion reliability.
Features
- Extreme Environment Adaptability: The material and surface treatment allow it to perform well in harsh conditions like high/low temperatures, humidity, corrosion, and minor impacts, meeting the stringent requirements of explosion-proof, rescue, and aerospace applications.
- High Load Capacity & Lightweight: Based on 7075 aerospace aluminum and an optimized structural design, it achieves high load capacity (Static Load ≥ 500 kg) while ensuring lightweight, contributing to improved robot endurance and movement efficiency.
- Precision Motion & Low Noise: High machining precision (key dimension tolerance ±0.01mm) and excellent surface finish (Ra ≤ 0.8μm) ensure smooth, precise transmission and very low operating noise.
- High Integration & Reliability: The design considers interfaces with components like servo motors and harmonic drives for easy integration. The monolithic forming process reduces assembly errors and significantly enhances the overall structure's rigidity and reliability.
- Long Life & Low Maintenance: Excellent wear resistance and fatigue resistance grant it a super long service life, reducing the equipment's total lifecycle maintenance costs.
