ARRANGEMENT FOR DETECTING THE LOAD OF A CHISEL OF CUTTING MACHINES

摘要

The invention relates to a device for detecting the load of a chisel of cutting machines, wherein the chisel is accommodated in a chisel retainer fixed on a rotatably supported tool carrier, a chisel bushing being received between the chisel and the chisel retainer, wherein the chisel bushing is fixed in the chisel retainer at the end area facing the chisel retainer, for example by means of a press fit, a gap is formed between the chisel bushing (4) and the chisel retainer (1) in the area adjacent to the end area fixed in the chisel retainer (1) in the direction of the chisel tip (3), wherein the gap extends to the end of the chisel retainer (1) facing the chisel tip (3) and measuring elements for measuring bending and axial forces on the chisel bushing (4) are arranged in the gap.
