Tool holder for a machine with a positioning system

Abstract

A tool holder for a machine includes a frame including at least one hook-shaped cut-out for receiving a first bracket pin of a tool and a least one partial cut-out for receiving a second bracket pin of the tool; an actuator connected with one end to the frame, the actuator including an actuator housing arranged movable compared to the frame upon activation of said actuator, the actuator housing further including lock fingers designed to change the shape of the at least one partial cut-out so that second bracket pin of the tool can be locked in the tool holder and the at least one partial cut out, respectively; and an actuator positioning system including a pattern, a sweep sensor, a processor and a computer readable memory. The sweep sensor is arranged on the frame and the pattern is arranged on the actuator housing, whereby the pattern is designed so that the sweep sensor can detect the pattern and generate a corresponding signal, which can be analysed using the processor and the computer readable memory for providing information relating to the actuator.
