End-Effector Mounting Plate

Product Specifications

Technical details and manufacturing context for End-Effector Mounting Plate

Definition

The End-Effector Mounting Plate is a critical component within a Robotic Arm Assembly, serving as the standardized mechanical and electrical interface between the robot's final axis (wrist) and the attached end-effector, such as grippers, welders, or sensors. It ensures precise alignment, secure attachment, and reliable transmission of power and signals. The plate is typically made of aluminum alloy (e.g., 6061-T6) or steel (e.g., AISI 1045), with an anodized surface treatment for corrosion resistance. It features a bolt circle diameter of 50 mm conforming to ISO 9409-1, with a center hole of 20 mm for cable routing or alignment. The thickness ranges from 10 to 20 mm, and the weight is between 0.5 and 1.5 kg. The plate is designed to operate in temperatures from -40°C to 85°C and has an IP54 rating for protection against dust and water splashes. It can handle a maximum static load of 500 N, with dynamic loads being lower. The flatness and parallelism are specified at 0.05 mm per ISO 1101, and the surface roughness is Ra 1.6 per ISO 4287. The interface size is ISO 9409-1-50-4-M6, defining the mounting hole pattern. This component ensures repeatable positioning through alignment pins or dowels, and integrated pass-through channels allow for pneumatic lines, electrical cables, or data connections. For procurement, verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges for typical configurations.

Working Principle

The plate is rigidly bolted to the robot's wrist flange. It provides a flat, machined surface with a precise pattern of threaded holes (e.g., conforming to ISO 9409-1 or other standards) for mounting the end-effector. Alignment pins or dowels ensure repeatable positioning. Integrated pass-through channels may allow for pneumatic lines, electrical cables, or data connections to route from the robot arm into the end-effector.

Frequently Asked Questions

What is the standard interface size for this mounting plate?

The interface size is ISO 9409-1-50-4-M6, which defines the bolt circle diameter of 50 mm and the mounting hole pattern. Always verify the exact standard with the manufacturer for your specific robot model.

What materials are available for the mounting plate?

The plate can be made of aluminum alloy (e.g., 6061-T6) or steel (e.g., AISI 1045). The choice affects weight and stiffness. Confirm the material grade with the supplier for your application.

Can the plate handle high loads?

The maximum static load is 500 N, but dynamic loads are lower. The actual capacity depends on the plate size, thickness, and material. Always consult the manufacturer for load ratings.

What is the operating temperature range?

The operating temperature range is -40°C to 85°C for anodized aluminum. Verify that this range meets your environmental requirements with the supplier.
