Abstract
The invention relates to a clamping system for clamping a number of tools wherein said system comprises: a body; an elongated groove arranged in the body for reception of a clamping part of at least one tool; at least one pusher element extendable into the groove for pushing the clamping part of a tool against a wall of the groove; wherein shape imposed displacement means for displacing the at least one pusher element from a first position substantially freeing the groove, enabling insertion of the clamping part of a tool into the groove, towards a second position, in which the at least one pusher element extends into the groove.
Claims11
A clamping system for clamping a number of tools, said system comprising:
- a body;
- an elongated groove arranged in the body for reception of a clamping part of at least one tool;
- at least one pusher element extendable and retractable from the body and into the groove for pushing the clamping part of a tool against a wall of the groove;
- and
- a shape imposed displacement mechanism operatively engaging the at least one pusher element to displace the at least one pusher element from a first position retracted within the body and substantially freeing the groove, enabling insertion of the clamping part of a tool into the groove, towards a second position, in which the at least one pusher element extends from the body into the groove,
- wherein the shape imposed displacement mechanism comprises at least one pair of wedge shaped elements, and wherein the wedge shaped elements shift along each other and are arranged between the body and the at least one pusher element,
- wherein the at least one pusher element comprises a pin extendable into the groove and a first spring arranged between the pin and the at least one pair of wedge shaped elements of the shape imposed displacement mechanism, and
- wherein at least one of the wedge shaped elements directly engages the first spring.
