THREE-DIMENSIONAL FIVE-AXIS CUTTING HEAD AND CONTROL METHOD THEREOF

The present invention relates to the field of laser processing and specifically provides a three-dimensional five-axis cutting head and a control method thereof. The three-dimensional five-axis cutting head includes a nozzle, where a left height sensor is disposed on a left side of the nozzle, a right height sensor is disposed on a right side, and a middle height sensor is disposed between the left side and the right side; and the nozzle is provided with a follow-up assembly, the follow-up assembly is connected to a swing shaft, the swing shaft is connected to a rotation shaft, and the rotation shaft is connected to a power assembly. Compared with the prior art, in the present invention, the height sensor is used to detect a height distance from the nozzle to a non-metal workpiece in real time, a vertical distance is obtained through calculation, and then a follow-up assembly of the three-dimensional five-axis cutting head is adjusted according to the vertical distance and a set height distance, so that the height from the nozzle to the non-metal workpiece is always kept at the set height.
