Design and Operating Principle
Toggle-lever kinematics multiply force near the closed position, giving a high clamping force at the moment of gripping. That makes radial grippers strong relative to their size.
Adjusting the opening angle lets users limit the swing to what the application needs, reducing cycle time and interference while keeping the option of a full 180° opening.
Radial grippers move the fingers on an arc; finger design should account for the closing path.
Integration and Selection
Set the opening angle for the application and design fingers for the closed geometry. Check gripping force at the actual finger length.
Add end-position sensing and plan clearance for the swinging fingers.
