Abstract
An interface between two parts of a tool system is proposed, in particular of a metalworking tool (1), having a holder (3) with a recess (31) and a replaceable head (5) disposed in axial continuation to the holder (3) including an extension (33) which can be inserted into the recess (31), and having a clamping device (19) to attach the replaceable head (5) to the holder (3). The clamping device is characterized by the clamping device (19) having a pull stud (41) and an eccentric cam (21) which displaces same in the axial direction, where the eccentric cam (21) can be actuated by way of a peripheral surface (17) of the metalworking tool (1).
Claims13
Interface between two parts of a tool system, especially of a metal-cutting tool, with a retainer comprising a recess, and an exchangeable head, comprising an appendix, which can be inserted into the recess, the exchangeable head is arranged in axial prolongation to the retainer, and with a fixture to fix the exchangeable head on the retainer, characterized in that the fixture comprises a tension-bolt and an in axial direction displacing eccentric element, wherein the eccentric element is operable over a peripheral area of the metal-cutting tool, and that the tension-bolt comprises a stud, which can be inserted into the eccentric, comprising a first clamping surface, and that the eccentric element comprises a second clamping surface, wherein the distance between the second clamping surface to a rotary axis of the eccentric element is different, wherein the first clamping surface of the tension-bolt is formed convex and the second clamping surface of the eccentric element is formed concave.
