Method and device for controlling the position of a tool holder in the tool support of a tool-changing device and for cleaning the coupling surfaces between the tool support and the tool holder

摘要

The invention relates to a method for checking the position of a tool carrier in the tool holder of a tool changing device and for cleaning the coupling surfaces between the tool holder and the tool carrier and a device for performing this method. The conical mounting hole of the tool holder is supplied with compressed air via a system of holes and milled holes in the tool holder so that it is distributed in a ring shape in the mounting hole and cleans the mounting hole and the entire area of the fit between the tool holder and tool holder when installing the conical clamping pin . The compressed air flowing in creates a dynamic pressure after clamping the tool, which the machine tool registers as a control signal for the release or blocking of the next operation.
