Mini Compliance Device (MCD124) Overview

The Mini Compliance Device (MCD124) is designed for small grippers, providing precise compliance in the X-Y plane and angular compliance around the α axis, while maintaining rigidity in the Z direction. It is equipped with pneumatic controls to manage positioning and locking.

Key Specifications

• Weight: 204 grams
• Maximum Radial Compliance (X-Y): ±1 mm
• Maximum Angular Compliance (α): 10°
• Locking Force in Central Position: 200 N at 6 bar pressure (F2)
• Locking Force in Off-Centre Position: 20 N at 6 bar pressure (F3)

Functional Features

• Compliance: Allows movement in X-Y directions and angular adjustment around α, enabling precise alignment and compensation during gripping operations.
• Rigidity: The device is rigid along the Z-axis, ensuring stability in vertical direction.
• Pneumatic Control: One air channel maintains the central zero position, while a second air channel locks the device in any offset position, providing flexibility and secure positioning.

Mechanical and Dimensional Details

The device includes multiple mounting points with M3 screws and precision holes (Ø5 H7 +0.012, Ø3 F7) for accurate assembly. Dimensional tolerances are tight, with positional accuracy of ±0.02 mm on key features. The device has a radius of 25 mm and an angular range of 25° with a 7.75° step or related parameter.

Applications and Usage Recommendations

The MCD124 is ideal for integration with small grippers in robotic or automated handling systems where precise compliance and locking are required. Its pneumatic locking system allows quick switching between free compliance and fixed positions, enhancing operational flexibility.

Summary of Critical Parameters

Best Practices

• Ensure pneumatic supply is regulated to 6 bar for optimal locking force.
• Use the central air lead to maintain zero position during operations requiring precise alignment.
• Engage the offset locking air lead only when fixed positioning away from zero is necessary.
• Verify mounting tolerances and screw torque to maintain device accuracy and repeatability.
