摘要： The present invention is a tool changer for electrical discharge machine tool (100), in particular for loading and unloading at least one tool electrode holder to be mounted in a chuck of the electrical discharge machine tool for machining a workpiece. The tool changer comprising:
a. a base (2) having a back wall (3c) and two side walls (3a, 3b), wherein on each side wall a linear guide is provided horizontally;
b. a holding plate (7) coupled to the linear guide to allow the displacement of the holding plate on a horizontal plane on the linear guide in its longitudinal direction defined as extending direction;
c. a plurality of forks (9) for receiving the tool electrode holder (41) mounted on the holding plate;
d. a driving unit connected to the holding plate to enable the movement of the holding plate between a retracted position and an extending position, wherein in the retracted position the holding plate is positioned closely to the back wall and in the extending position the holding plate is moved away from the back wall, wherein the driving unit includes a first actuator and a second actuator, the longitudinal axis of each actuator being arranged at a defined angle to the extending direction of the tool changer..
