Abstract
An automatically focusing structure of laser sculpturing machine, including an electronic probe structure vertically mounted on a blade seat of the laser sculpturing machine. The electronic probe structure includes a circular tube with a certain length. The top section of the probe structure is formed with a flange. An upper and a lower sections of the circular tube are respectively formed with two annular grooves for locating a locating rod of the blade seat. The circular centers of the upper and lower end faces of the circular tube are respectively disposed with openings for a first and a second inner electronic detection bars to outward extend therethrough. An electric working bench is lifted in Z axis direction to make the surface of a work piece contact with the probe. The focus of a lens memorized by a software is calculated and then the working bench is accordingly lowered to the focus face to complete the automatically focusing operation. During working, the electronic probe structure is upward restored so as not to touch the work piece.
