The present invention relates to a workpiece support plate for a laser cutting machine, which includes a plate part having at least one insertion hole formed on one side of an upper part and a supporting pin having a lower part being inserted into the insertion hole and one side of an upper part supporting a bottom of a workpiece. The plate part has a first plate having a first groove part formed on one side of an upper part, and a second plate having a second groove part which corresponds to the first groove part and is formed on one side of an upper part. The first plate and the second plate are combined with each other. The insertion hole is formed as the first groove part faces the second groove part. By this, the present invention has the effect of improving work efficiency by shortening replacement work time, by being able to replace a supporting pin fused with dross, in case the dross is fused on the support plate and degrades flatness of the supported workpiece. Also, the present invention can prevent the workpiece from being damaged, by preventing a laser beam passing through the workpiece from being reflected to the bottom of the workpiece through the support plate during laser cutting processing, by arranging the bottom of the workpiece to be separated from the upper part of the support plate sufficiently due to a space formed between the supporting pin and a supporting protruded part. |
