Articulated Joints for Manipulator Arms

Q: What is the typical load capacity of articulated joints?

The rated load capacity for articulated joints in this directory ranges from 50 to 500 kg, depending on the model and application. This value must be confirmed with the manufacturer for the specific joint.

Q: What rotation angles are available?

Articulated joints typically allow rotation angles from ±90° to ±180°, limited by mechanical stops and hose routing. The exact angle depends on the joint design and should be verified with the supplier.

Q: What standards apply to articulated joints?

Relevant standards include ISO 9283 for positioning repeatability, and applicable standards for operating pressure and leakage, IEC 60529 for protection class, and ISO 9409-1 for mounting interface. These standards serve as references for verification, not as proof of compliance.

Q: How do I choose the right material for an articulated joint?

Material selection depends on factors like strength, corrosion resistance, and weight. Common materials are alloy steel, stainless steel, and aluminum alloy. For example, 6061-T6 aluminum and 304 stainless steel are listed as reference grades. Consult the manufacturer for application-specific recommendations.

Technical details and manufacturing context for Articulated Joints

Definition

Articulated joints are pivotal mechanical components used in manipulator arms to enable controlled rotational movement between arm segments. They provide the flexibility and range of motion necessary for precise positioning and manipulation tasks in industrial applications. These joints typically consist of a rotating mechanism, such as bearings, bushings, or direct shaft connections, that allows rotation around one or more axes while maintaining structural integrity and load-bearing capacity. The design of an articulated joint must balance strength, stiffness, and weight to meet the demands of specific applications. Common materials include alloy steel, stainless steel, and aluminum alloy, each offering different trade-offs in strength, corrosion resistance, and weight. Key parameters to consider when selecting an articulated joint include rated load capacity (50–500 kg), rotation angle (±90° to ±180°), positioning repeatability (±0.05–±0.1 mm per ISO 9283), operating pressure (1.0–1.6 MPa), operating temperature (-40°C to 85°C), protection class (IP54–IP65 per IEC 60529), material grade (e.g., 6061-T6 aluminum or 304 stainless steel per ASTM B211/ASTM A276), weight (2.5–15 kg), bearing type (crossed roller or ball per ISO 76), leakage rate (<0.05 mL/min), mounting interface (ISO 9409-1-50-4-M6), and maximum torque (100–1000 N·m). These values are reference ranges and must be verified for the specific model and application. Standards listed serve as procurement and verification references, not as proof of certification or compliance. Always consult the legal manufacturer or supplier to confirm model-specific specifications and applicable standards.

Working Principle

Articulated joints connect two arm segments with a rotating mechanism, typically using bearings, bushings, or direct shaft connections. This allows controlled rotation around one or more axes while maintaining structural integrity and load-bearing capacity. The joint's design ensures smooth movement and precise positioning, with mechanical stops and hose routing limiting the rotation angle. Lubrication and sealing are critical for reliable operation and to prevent leakage, especially in hydraulic or pneumatic applications. The joint must be selected based on load, speed, and environmental conditions to ensure safe and efficient operation.
