Zusammenfassung:The invention provides a suction clamp for clamping an object. The suction clamp comprises a base structure comprising a base and a connection area, and a first pad for receiving the object. The suction clamp further comprises a resilient member connecting the first pad to the connection area of the base structure such that the first pad is moveable relative to the base between a receiving position for receiving the object and a clamping position for clamping the object, wherein the resilient member is adapted to bias the first pad to the receiving position. The suction clamp further comprises a suction opening arranged in the base and adapted to be connected to a suction device for providing a suction force for clamping the object on the first pad.
