The invention relates to the technical field of
laser cutting machines, and discloses a low-pressure
oxygen cabin body
laser cutting machine which comprises a multi-degree-of-freedom platform and a
welding frame connected with the multi-degree-of-freedom platform and further comprises a calibration plate, a vertical
moving frame, a horizontal
moving frame and a main shaft rotationally connected to the
welding frame. The output shaft end of the
servo motor is in transmission connection with the main shaft through a synchronous belt, a vertical transmission module for driving the vertical
moving frame to move up and down in a reciprocating mode is installed on the
welding frame, a
horizontal transmission module for driving the horizontal moving frame to move left and right in a reciprocating mode is installed between the horizontal moving frame and the vertical moving frame, and the reciprocating displacement strokes of the horizontal moving frame and the vertical moving frame are adjustable. Through a bidirectional adjustable reciprocating vibration mechanism of the vertical moving frame and the horizontal moving frame and in combination with a dynamic
stroke adjusting function, high-frequency micro-amplitude vibration is generated when a
laser beam acts on a material, so that the
molten material is efficiently discharged, the smoothness of a
cutting surface is improved by more than 40%, and the
slag adhering rate is reduced to be less than 15% of that of traditional equipment.
