Centring block for centring a tooling board in a flat bed die-cutting, stripping or blanking machine and centring assembly

A centering block comprising:

• a first clamp and a second clamp which are arranged adjacent to each other creating a reception space for receiving an alignment element, wherein the first clamp and the second clamp are configured to be mounted linearly movable in a first direction and separately movable from each other in a second direction perpendicular to the first direction, and
• at least one biasing means which is configured to bias the first clamp and the second clamp towards an aligning position against the alignment element,
• wherein each of the first clamp and the second clamp comprises a stop portion configured to restrict a movement of the alignment element in an insertion direction and an opposite direction to the insertion direction and to fix the alignment element in a center position,
• wherein the first clamp and the second clamp are fastened to a first slidably moveable shaft and a second slidably movable shaft, respectively,
• wherein each of the first slidably moveable shaft and the second slidably movable shaft include a bearing element, wherein each bearing element provides a contact surface for the biasing means,
• wherein the centering block further comprises an unlocking element which is moveable in a release direction against a biasing force of the biasing means, and
• wherein each bearing element rests on the unlocking element when the first clamp and the second clamp are in the aligning position such that the first clamp and the second clamp are lifted when the unlocking element is moved in the release direction,
• wherein the centering block further comprises a handle which is in operative connection with the unlocking element such that the unlocking element is moved in the release direction when the handle is actuated, and
• wherein the handle and the unlocking element are connected and configured such that a movement of the handle in the first direction results in a movement of the unlocking element in the second direction.
