The utility model relates to the technical field of
laser cutting, and discloses a
cutting device which comprises a supporting table, a mounting plate, a rotating shaft, a
thumb cylinder, an electric push rod, a first moving plate, a first rack, a first gear, a
laser cutting head and a linear moving module. During use, the
thumb cylinder is controlled to work, and plates to be
cut can be clamped and fixed. And then, the driving piece is controlled to work, and the
laser cutting head can move in the width, length and height directions of the supporting table. The function that the cutting head freely moves in a three-dimensional space is achieved, and therefore different shapes can be
cut on the sheet
metal part. And moreover, the electric push rod is controlled to work, and the first moving plate can drive the first rack to move. Under the meshing effect between teeth, the first gear can drive the rotating shaft to rotate, then the
thumb air cylinder is driven to rotate, and finally the angle adjusting function of the sheet
metal part is achieved. Therefore, the multiple faces of the sheet
metal part can be
cut through one-time clamping. Time and labor are saved, and cutting efficiency is improved.
