Plate and profile laser cutting all-in-one machine

The invention discloses a plate and profile laser cutting all-in-one machine which comprises a cutting machine body, a plate cutting mechanism and a profile cutting mechanism and is characterized in that the profile cutting mechanism comprises a profile cutting guide rail installed on the side portion of the cutting machine body and at least two sets of chucks located on the profile cutting guide rail. The sectional material cutting guide rail is installed on the side portion of the cutting machine body, the sectional material cutting guide rail and the plate cutting mechanism share the cutting platform, so that the structure is compact and can be manufactured together, meanwhile, the mode that two sets of three-dimensional coordinate systems are adopted in the past is changed into the mode that only one set of three-dimensional coordinate systems is needed, and the cutting precision is high; besides, the sectional material can be not limited by the bottom (except the ground), the bottom of the workpiece can
