Clamping fixture for workpiece with outer tooth system

摘要

The workpiece is clamped on the rest surface. A securing device stops it from spinning during processing. The clamp has a component (22) that has at least two teeth that are spaced along a circular arc. It engages with the workpiece's outer tooth system (17) at least two places along the circumference. The component can be mounted allowing swinging motion, with the swinging axis (25) parallel to the axis of the workpiece's hole. Spring pressure can be used to engage the component and the tooth system.
