This invention discloses a laser cutting machine for precision workpiece machining, capable of automatically positioning the workpiece. It relates to the field of precision workpiece machining technology and includes a worktable and a positioning assembly. A support roller is rotatably connected to the center of the worktable, and a waste bin is located below the worktable. A three-axis slide module is installed at the rear of the worktable, and the output end of the three-axis slide module is connected to a laser cutting head. During positioning, the drive motor first drives the two slide blocks to move synchronously towards each other via positive and negative threaded screws. A buffer spring pushes the roller frame and its rollers to contact the workpiece. The buffer spring, with its low elastic coefficient, ensures a gentle contact force. After initial positioning, the slide blocks continue to move, compressing the buffer spring. The drive slotted plate, through rollers, drives the positioning seat and positioning plate to complete the final rigid clamping. This process of first guiding and then locking can complete high-precision automatic centering within seconds, resulting in high positioning accuracy.
