Clamp device for centring test object in balancing machine has at least 3 vertical centring pins displaced radially in synchronism against common spring force

摘要

The clamp device has at least 3 vertical centring pins (12,..14), fitting into a central bore in the test object, supported for radial movement and coupled together for lying along a circle with a common center point in each position. The centring pins are moved radially in synchronism against the force of a spring (19).
