AUXILIARY DEVICE FOR TOOL CHANGE IN TOOL HOLDER OF CNC MILLING MACHINE

摘要

The present invention relates to an auxiliary device for tool change in a tool holder of a CNC milling machine. The auxiliary device can separate a tool by force from a main shaft at a cutting tool changing point, and comprises: a main shaft installed in a CNC milling machine and equipped with a clamping device inside; a plurality of tool holding devices installed in a tool magazine of the CNC milling machine in a circulation method; and a detection device installed in the CNC milling machine and also allowing picking up the tool or changing motion to be linked in the tool holding device. Regarding changing the tool, the detection device linked with the tool holding device sends a signal immediately when the tool holding device touches the tool, the CNC milling machine performs cutting at the most accurate tool changing point and then discharges the tool at a proper time.;COPYRIGHT KIPO 2014
