The utility model belongs to the field of mechanical tool positioning, and relates to a 2D plane
laser cutting plate positioning tool which comprises a supporting frame, transverse and longitudinal positioning reinforcing ribs, plate supporting sawteeth, a side limiting seat, a
tail end limiting seat and a mounting mechanism of the
tail end limiting seat. The supporting frame is formed by
welding rectangular steel pipes, and transverse and longitudinal reinforcing ribs are arranged in the supporting frame to enhance rigidity. The plate supporting sawteeth are installed on the reinforcing rib grids and used for supporting a to-be-
cut plate. The side limiting seat and the
tail end limiting seat limit transverse and longitudinal movement of a plate respectively, are fixed to the frame through the adjustable mounting mechanism and are provided with strip-shaped adjusting holes so as to improve positioning flexibility. When the
laser cutting device is used, an operator places a plate on the frame, the position of the limiting base is adjusted to achieve accurate positioning, and then the
laser cutting device is started. The plate positioning device is simple in structure, convenient to operate, accurate in positioning and high in efficiency, effectively solves the problem of plate positioning, improves the cutting quality and efficiency, and reduces the production cost and the
rejection rate.
